My mom had a mark on her arm that was pretty normal, it really only looked like a mole. My dog would sniff at it for upwards of a minute every time she saw her so I told her to get the spot looked at. She just got it biopsied and the results came back yesterday. She has Melanoma and is going to a cancer specialist next week. She's cancer free guys! Has been for a while now. I get pinged on this post every once in a while, you guys are so sweet.
@@tomgvaughan she's getting a surgery next month... we think we caught it early! It's really all thanks to my dog, the spot looked super normal to us. If all goes well she'll be cancer free by Christmas. Thanks for asking :D
Was slightly surprised to not see this mentioned.. I recently saw a video online of a spider caught in a cup, and a pair of girls were trying to take a video of it with their smartphone. When they would tap on the table the spider wouldn't flinch, but every time they tried to focus on the spider by tapping their phone screen where the spider was, the spider would flinch as if it was responding to the tap directly. It was discovered that the spider was responding to the lidar or infrared signal being emitted from the phone every time it sent out a beam to focus. Apparently spiders and some other animals like deer can see this spectrum, but humans can not.
Radio waves, and any form of light that way can be seen. Our eyes are nothing more than visual-wavelength radio dishes. Its very possible if we find alien life, they could see completely different spectrums. Maybe only AM, maybe only Microwaves, maybe only Gamma waves. Assuming they see at all of course. Basically if it can be picked up through a radio dish, it can be seen by an animal with eyes tuned correctly. And also that all radio dishes are effectively man-made eyes, more so than cameras weirdly.
In the summer of 1992, my wife and I took a trip to the Florida keys. One of the events was a day at the Dolphin Research Center in Marathon Key. It was one of the most amazing experiences of my entire life (for many reasons that I won't go into here). But the most incredible thing happened when we were finally allowed to get in the water with the dolphins. They were not captive; but instead free-swim mammals that could leave out to open ocean anytime they wanted - they just liked to hang around and work with the Marine Biologists (and the visitors!). I climbed down into the lagoon first. and the dolphins came over & checked me out; splashing, "talking", etc. However, when my wife got in the water, something completely different happened...one-by-one, all the female dolphins started to gather around her in a circle; clicking incessantly. My wife started to get a little unnerved by this. The Bilologist was watching from the platform, and asked me "Is your wife pregnant?" I told her "Yes, about 5 months". She said "They know. They can see the baby. As long as she's in the water, they will not allow anything to come near her." How incredibly cool is that ?!?
INCREDIBLY COOL is how that is!! There are stories of women who work with wolf sanctuaries - and the wolves can smell when a woman is pregnant and are clearly DELIGHTED that there is a puppy on the way :D
@@bookmouse2719 I think they're a lot smarter than most people realize... A friend of mine is (well - was :-) a surfer from Ventura, CA. He was out one day in the early morning; surfing off the coast of Ojai. One of his friends who was on-shore started hollering at him - there was a 12 to 15' Great White on the surface of the wave just a couple yards behind him. He said his heart almost jumped out of his chest. Then out of the corner of his eye to the left, he saw 3 dorsal fins cutting across the face of the wave heading directly at him. He told me that at that point, he figured his time was up, and started praying...all while trying not to lose his balance. The 3 fins split up and swam around him on either side. When he turned to see what was going on, there were 3 dolphins heading right toward the shark. The shark broke off his pursuit, and dropped back. Two of the dolphins continued to chase it away; the third one swam alongside my friend until he reached the shore break. It lingered in the shallows for a few seconds while my (truly blessed!) pal grabbed his board and walked out of the water. Then the dolphin turned and swam off. My friend said he sat down on the sand - and cried his eyes out 15 minutes.
my childhood dog actually found skin cancer in my dads forearm when i was growing up. Its was a spot she was fixated on and anytime he was around she would keep going back to that spot. He got checked soon after and come to find out she detected very early melanoma and basically saved my dads life because it was found so early. More so than for hospitals, i think having a dog in the home that can smell cancer is extremely valuable, I'm not sure how we would go about that but if your dog every gets fixated on a spot on your body, best to get it checked.
There are quite a few stories in this same category. I heard one about a lady whose dog kept pawing at the back of her leg, then eventually started nipping at the same spot, which finally got her to check the spot, go to the doctor, and have the melanoma removed.
@@boganvogue6694 No, the heinous attempts to make money are by the corporate healthcare providers who vigorously and relentlessly try to stomp on anything that might somehow diminish their profit margins. In the video, Joe specifically mentions an organization that is working on a standardized method of training the dogs for this task, which means your comment is obnoxiously ignorant.
@@boganvogue6694 Dogs are routinely trained for finding medical issues, so nothing stops a dog from flagging something they find off without training - They just don't have any context for what it is, they just identify something as different and are curious or concerned/irritated. But there are also plenty of properly trained personal assistant dogs who can sense different conditions, like dogs that help their owner identify blood sugar levels etc. There's also rats that can successfully sniff out things like cancer and land mines - dogs are not unique in this. Just because you lack all kinds of productive potential doesn't mean other animals do.
A lot of dogs are fixated on people’s crotches, but I don’t think that means there’s something wrong with those people. If dogs have such sensitive noses, why do they need sniff each others butts from so close up, because I understand the scent of the excretion from anal glands is extremely strong.
@@kellydalstok8900 They sniff each others butts because unlike humans they have a much more complex registration and separation of scent; The closer they are to the scent the stronger they are likely to perceive the different subtleties, so we can safely assume they get more stimuli + a clearer "image" of whatever information it brings them. Not unlike you bringing something closer to your eyes to see more detail or get increased perception; You can see and hear your friend from 10 meters away, so why stand 1-2 meters away? Or bring a flower closer to your nose to smell for that matter. Since dogs are notoriously bad at bringing their calling cards with them, they do the butt sniff instead, as the anal glands supposedly reveals a lot of information about the other dog to them. There is nothing wrong with the crotches dogs sniff, there is just a lot of scent information (and the dog is unlikely to behave "strange" when doing it) - it's a bit of a weird analogy as likewise doctors talk to a lot of people around them that aren't sick. (But if you meet a doctor that looks at your arm and remarks "you might want to get that looked at" you probably should - regardless how many healthy arms that doctor has looked at prior to it)
Echolocation Sense: I learned the "Daniel Kish style" human passive and active echolocation (even though my vision is perfect). It is simultaneously suprisingly simple and difficult. The concept is simple: You just have to learn to interpret, single out, enhance, discard and/or focus on specific sounds. But the difficult thing is the "sound vocabulary" that you have to build up by making a tongue click at literally everything you "see". It's just like learning Chinese is theoretically simple to learn, yet you have to study and learn thousands of vocabulary words in order to understand it. I'm at an active echolocation level now where I can comfortably walk through my own rooms, dangle along a forest path without swaying to the sides too much, find my way around in rooms and buildings where I've never been before. Perfectly blindfolded, of course. I've even trained myself to interpret the sound as "images". This imaging technique can be a blessing *and* a curse because once aquired I even see sounds when I try to fall asleep. Tremor Sense: I'm experimenting making this sense available for humans, too. I achieve this by combining a relatively small compression spring that has a small rubber ball on the one side and a magnet on the other. Then, I attached an equally sized magnet to the base of my thumbnail. This construction allows me to put this sense on and off whenever I like. The magents are very thin and small so they usually don't bother me. Now, whenever I move my hand - and especially my thumb - the vibrations and kinetic energy gets amplified by this small self-built tremor sense as the ball oscillates on the small compression spring. It is a really weird feeling because my brain interprets the vibrations that I can newly sense now as sound. So if the self-built compression spring tremor sense swings back and forth at 5Hz I'll hear 5 Hz. The same goes for smaller and higher frequencies. The thumbnail is very sensitive and ideal for things to stick onto without irritating the skin. I'm working on a combination of differently sized compression springs on a single stick-on tremor sense construction so that I'll be able to "hear" more than just one frequency at a time. Polarization sense: Humans can see the polarization of light. It's called Haidinger's Brush and is located in the center of the visual field. But it is way too faint to have any practical use in day to day life. However, we can wear passive linearly polarized glasses where the left lens polarizer is rotated to 45 degrees and the right one to 135 degrees. Putting these glasses on you can see stress patterns as colored patterns in conditions where there is polarized light and/or polarized filters. And you can make out the general polarization of light in the form of (dependently monochromatic) light intensity differences. If you now wear appropriate glasses with two differently colored lenses (that don't possess a stress pattern or birefringence) you can even see this polarization in a dichromatic gradient instead of a situational monochromatic one. With the right interfernce glasses (like: Infitec's Triple Band Pass Interference Glasses) you can make the colorful stress patterns (birefringence) even way more visible, sharp and distinct AND give (monchromatic) polarized light a dichromatic gradient. Tetrachromacy or more: I'm working on making humans more than trichromats by bestowing a fourth cone or something similar onto them. Earlier, I mentioned Infitec's Triple Band Pass Interference Glasses (TBP glasses) that split the RGB cones in our eyes into R1G1B1 in the left and R2G2B2 in the right eye. This is achieved by the combination of multiple band pass filters in a single lens. If we take the green cone for example the TBP glasses split the cone sensitvity into two parts: The left eye now only receives a green where all the green cones that are more sensitive to red-ish light are cut off and the right eye now only receives a green where all the green cones that are sensitive to more blue-ish light are cut off. In effect, it makes 2 cones out of one. And because a lesser sensitivity of a cone type results not just in a perceived luminosity change but also in a perceived color change - because the surrounding colors shift closer in to the color space of the diminished color - you implement impossible color combinations into your vision. This happens to all three cone types and enables you to make out color differences you could have never imagined being able to differentiate before. Unfortunately, you won't see any new "primary" color. However, I feel like I can see new secondary and tertiary colors / color differences. With only a single magenta lens over one of my eyes I calculated that I can even see at least 1.25 times the colors (especially in the yellow-green/lime and cyan-green/turquoise color space). Wearing this single magenta lens allows me to make out double the color differences in the lime and turquoise color space. So where the green to greenish-lime colors #00FF00 and #20FF00 look identical to me under normal conditions, with the single magenta lens on these two colors are as different to me as #00FF00 and #40FF00 (where I can normally see a slight difference). So this an increase in color discriminability from 40 down to 20, that is double the color discriminability. I can make out details in cyan to yellow things I could have never noticed before, even (and especially) on RGB screens. Yellow is as different from green to me now as red is from green. And red glows like a beacon. My subjective color contrasts are definitely a lot higher. And this is only the beginning. I'm working an active XR glasses and software (the glasses I mentioned before are all passive) that implement impossible colors into the perceived color spectrum. So like a red-orange, a red-yellow, a red-lime, red-green, a magenta-green, a cyan-red, a green-purple, etc. With this technology you can implement at least 155 new distinct (impossible) color combinations into your color spectrum. And oh boy, I've already seen it. The camera and color pass through quality of the XR glasses I used were abysmally bad and yet it was so beautiful. You can imagine what I saw with it like Star Trek's Geordi La Forge's VISOR. (There are clips online that show what he'd see. It was in an offical episode.) There is color in color in color in color and it's not an exaggeration. If you can learn to make sense of this even tetrachromacy seems inferior. As you might tell, I'm a sense researcher. I love senses because they are the only things that connect us to this world. If you can sense more of this world by acquiring more senses or enhance the already existing ones, this world will become even more beautiful and rich in detail.
@@r0cketplumber I have relatively recently made a new English UA-cam channel named "Ooqui" were I (inconsistently) post a 5 to 15 minute long video on the topic of "human senses" and how to enhance them. Until now, I've only made videos on enhancing color vision. But videos on human echolocation, tremor senses, polarization senses and more tetrachromacy will come eventually, too. On this here channel I write this comment with I've also made videos on enhancing human senses. However, these videos are in German and you'll most likely won't understand it. I don't have a blog, yet. But maybe soon. Other resources are difficult to provide because some of the things I learned are by experience and yet not studied enough. At least in the way I use them, as I tend to methodically and deliberately misuse ordinary things to turn them into new sensory experiences.
Sensory augmentation is something that has fascinated me since I first grokked it. It’s rare to hear about this sort of thing from legitimate researchers. A couple of years ago I got all excited about the idea of sticking magnets under the skin on my fingers but the materials and processes were far from perfect and potentially dangerous. Sorry to upset the grinder/bio hacking community but I think non invasive methods are the way forward.
@@frankdaze2353 I wouldn't call myself a "legitimate" researcher. However, I am very passionate about sensory augmentation and everything that comes along with it. In my opinion non-invasive methods of sonsory enhancement/augmentation is definitely the safer method. You could theoretically achieve a higher degree and quality of sensory augmentation via invasive methods but the risks are higher the more invasive the method becomes. I am personally focussing on non-invasive methods because they are more easy to achieve with a small budget, because they are safer, and because they are less permanent and thereby much more adjustable/configurable. If you implant a magnet inside of you finger tip you can't easily iterate and update the "version" of that magnet. If the magnet however is placed on top of the finger nail, for example, you can take it on and off anytime you like without much pain involved. That's also why I favor glasses over contact lenses in general. The option to turn a new sense on and off in extremely valuable.
Electric Eels - you missed those. Electric Eels can move forwards and backwards, without contacting anything, even in sediment-filled opaque water. They create an electric field around their body that enables them to sense what's around them through their skin. It's a bit like echo-location only using electricity rather than sound.
@@pauldeddens5349 I don't believe sharks produce their own electricity though; they sense electricity created by other things like the muscle contractions of fish or boat motors. Electric eels produce their own electricity and use it to kill their prey, and unfortunately the occasional person or horse (supposedly a gaucho crossing a river in South America perished this way). They also use different muscles to create different voltages depending on their goal (searching/hunting, stunning/killing, or communicating).
@@RyanDugan23 I thought sharks produced a very small current in order to find prey, like shining a flashlight. Though it is possible they just find ambient current in the water, i dont know.
I remember watching a news report years ago where a cat in a nursing home could sense the pending death of a patient. The cat was so accurate that the people working there notified the next of kin so they can make one last visit.
Tortoises don’t have ears yet can hear your voice and come to you when you call them. We think they know your vibrations. I own an exotic animal sanctuary and we were a tortoise rescue for 15 years. It’s an incredible phenomenon
It's called "Reptillian Hearing". You can experience this yourself. If you put your chin on a table and tap it, you can hear it through your bones. I have actually managed to hear through my fingers, it's kind of weird.
How about the dogs who are able to smell high sugar levels in Type 1 Diabetics, or the cat in the rest home who was able to tell when one of the patients was about to die, this was documented in over 100 cases. Animals are amazing! Thanks for sharing
I'm type 1 diabetic, and my cat has forcefully woken me up if my blood sugar crashes while I'm asleep. He's probably saved my life several times already.
I was a Dog Trainer for the U.S. Navy. For the most part I trained bomb,drug and cadaver dogs. When it comes to how dog's smell, the amazing part is their ability to distinguish each of these scents. An easy way to explain it is, when you pull up to a McDonalds, you smell food. A dog smells, beef, bread, catsup, mustard, potatoes, oil etc.. they can distinguish each ingredient. This is of course is how they find your "drugs" when they are encased in things like coffee or whatever you "try" to hide your drugs in. It's the same with human remains, even with all the other scents in the air, they break them all down and ignore what they are not trained to look for. It is really amazing.
All dogs have two incredible superpowers that you didn't mention. The first is the ability to spread out and occupy all the surface of any human's bed, and do it silently while you are asleep. The second is an exponential increase in the gravity affecting the hind end of the dog whenever the words "go to the vet" are spoken or spelled out. The butt of a thirty pound dog will weigh more than ninety pounds once the phrase is uttered.
Combined with their inability "drop the ball" and their ability to respond to "what's in our mouth?" with various evolutionary avoidance tactics, I believe this makes dogs the most interesting creatures on the list.
Regarding echolocation by blind people, I remember seeing a programme where a young blind guy was using just that to get around and was refusing to use a cane. Another blind person showed him that echolocation wouldn't let him know if there was a hole in the road in front of him, whereas a cane would have warned him that the ground wasn't solid ahead of him.
Also it's not precise since it can't properly distinguish these barriers. For example a pole verses many forming a fence. In crowded places people will register woefully awfully, animals, cars, moving momentary barriers. Source? I'm a blind person. I had a device doing it coz I have a bit of hearing loss too and it'd vibrate depending on distance and barrier. Kept sleeping off steps, gutters or bumps. I kept going round non-existence barriers or "seeing" a crowded street like a wall. And isn't that hearing finger movement universal, I mean it sounds different. Worst feeling is nail over rough brown braille paper.
@@CBEnoddyy You are full of ------. We can echo location, hear with our feet, just a dog tell smells with our nose, and some of ours can see magnetic line of force! And it proven all the back to the 60s.
As someone who has recently become visually impaired, I find it quite inspiring to learn about how are people have managed to sharpen their other senses in order to compensate. I have certainly noticed that I pay a lot greater attention to my sense of touch and for example use it to properly orientate my clothing when folding or getting dressed in a way that was very difficult when this first happened to me.
in my opinion the mantis shrimp is one of the weirdest but coolest Animal to existed, because it has 12 color cones (16 in some reports), which means they can see both ultraviolet and infrared. they also hit the hardest of any living creature because, their club like arm accelerates faster than a bullet out of a gun, which can break through shells.
@@alphagt62 Technically its in its own group, between lobsters and shrimp. Just visually resembles a shrimp. Current ideas focus around sociality, territoriality, and hunting. They are social creatures, who appear to communicate using UV (Or IR, its one of the wavelengths just beyond visible light), and using their iridescent paddles next to their heads, can reflect or alter the signal, as a response. They are also very territorial, and will generally obliterate anything that comes near its dens. A spotless den means a strong, evolutionarily fit mantis shrimp. And hunting, its hard to camouflage when you see that many spectrums of light. Most creatures sneak in predators blind spots by signaling with one spectrum or another. Like how many insects, fish, and even mammals glow under UV light. Seeing all of those wavelengths makes it easier to spot intruders into their dens, and hunt creatures hiding in sand and camouflaging among rock and plant. Why it needs 3 "pupils" is beyond me. Its not like they really could hunt three things at the same time. Maybe to keep an eye on opposing mantis shrimp, potentially during a mating season? I dont know enough about them.
@@pauldeddens5349 Maybe so they can focus vision across multiple spectra to make overlays of the thing they are focusing on. Pupils are focal points, so multi specrta layering when focusing on something.
I used to be a Sonar Tech in the Navy, and our man-made sonar works the same way as the bat's ears. The transducer switches between a "transmit" mode, where it can emit sound but can't hear, to a "receive" mode, where it can hear but not transmit so that it doesn't "blind" itself with every transmission. The stuff about "telepathy" in dolphins got me thinking about a couple of things though, as this same sort of "telepathy" is how I learned to "echolocate". By that I mean looked at an listened to subs recorded by people who had seen them before, figuring out what their diagnostic features were and learning to ID real ones in the wild. I imagine that dolphins would probably teach their children to hunt in a similar way. Of course, most of my own training didn't involve listening to recorded pings bouncing off of subs. Finding something you are screaming at is actually pretty easy so you don't have to spend much time on it. The vast majority of my own training revolved around detecting subs "passively", that is, just listening and and figuring out what it is you are looking at before you turn on that loud ass sonar that will give away your position. For every one hour I spent practicing at tagging and tracking active contacts, I probably spent 4 working through "grams", recordings of known subs that you have to ID based on the frequencies they emit. Bonus points if you can get range, bearing, course, and speed information from the gram. I imagine that there would be similar pressures on animals like dolphins, who would probably listen for the sounds of a school of fish before focusing their sonar on a known location, rather than clicking away using active search and scaring away all the fish. One good way to see if dolphins are teaching one another or transmitting information by mimicking the returned clicks from a given piece of stimuli may be to see if they are doing this for other, stranger sounds. Do dolphins ever mimic the tailbeats of a school of fish or the staticky clicking of a school of shrimp? I'd be interested to see if mother dolphins are mimicking very undolphinlike sounds to teach their children what prey sounds like.
Yup.. for sure it does.. would Love a ”in depth” video about that too.. with all the aspects and diff there can be..😌👌🏼.. Please Joe🥺.. do one..Thank You❤
The monarch butterfly is a good one. It's able to follow the migration flight patterns of distant ancestors skipping over generations who have never been on that trip.
In regards to using sound to determine structural integrity: I used to work on tanker ships that transport fuel for the Navy. We would always clean the tanks before we entered a shipyard for repairs. One of the times I thought it was very cool that the company occasionally hires experienced climbers to climb around in the tanks "sounding" the different parts of the metal structures to make sure the metal hasn't thinned to the point of needing to be replaced. Extra related info: A big part of my job was removing rust from the metal and painting over it. This is a big contributor to the thinning of the metal.

Heat sense... I remember taking a welding class in HS, and reaching towards something, and feeling that radiant heat, knowing it was about to hurt, but could not react fast enough to stop. I'll always remember how weird it was knowing that it was going to hurt, but being unable to do anything about it because it was so fast.
Yeah it's amazing how fast the brain is able to interpret impending events but the rest of the body can't react quick enough and when you think back on it it's like it happened in slow motion. I was a passenger in in a car going 55 mph that was approaching an intersection with a green light and I saw a car to my left run a red light and realized we were going to T-Bone it so i instinctively put my feet on the dash (bad idea- never do this!) as I tried to warn the driver but all that came out was "OH OH OH!" and WHAM! Everyone was okay except for minor injuries. One of my feet went through the windshield and the other foot went down below the dash as I flew forward because I had the automatic shoulder belt on but not the lap belt and the shoulder belt didnt lock immediately so I flew forward and when it locked it was like getting hit with a sledge hammer and cracked my chest plate. Good thing we didn't have passenger side airbags or it would've certainly broke my feet and legs. Good times!
Years ago I worked in a large photographic lab. Part of that was a blacked out corridor that went from six printing darkrooms to two paper processors. Two or three of us would be working in that area at the same time. We never collided with each other untill there was a cold going round that muffled our hearing, we had to start calling out to each other to avoid collisions.
Solpugids (sun spiders, camel spiders, wind scorpions) have unusual sense organs on the undersides of one pair of legs. Last I heard, no one has yet figured them out. I've watched the way they move and run. Very different movement patterns. Something different is going on with the way they are sensing. They often move like a leaf that has suddenly dislodged from a snag in a strong wind, and then travels five or ten feet and hits another snag, and suddenly freezes. Then it happens again, sometimes with a change in direction. They move fast and suddenly. They are apparently the fastest land arachnids.
I didn't need that. I didn't need that mental image. We don't even have scorpions here, but I'm imagining seeing a scorpion and it making a dash up my leg. Oh shit! 🦂

How do you keep on finding so many interesting topics?! You never disappoint. Love the videos and I love how you made analogies to help us understand what it’s like for animals to sense. So cool.
Here’s an odd one. My 10 year old nephew when visiting us a couple hours away from home had the ability to feel what direction north was… I tested him left and right (made sure to check at noon when Sun was above, no device or car queues present, etc) but he was 💯 accurate each time I’d ask. To this day he doesn’t know why/how but has an innate sense - only explanation I could find was a rare ability to feel magnetic fields (sounds crazy, I know).
Also, he travelled mainly SW to get here, and I would make a point to take confusing winding roads (sneakily) and then suddenly ask where north was. He wouldn’t think but 1-2 seconds before pointing. Super bizarre
not that out there, there's at least one tribe that uses cardinal directions instead of left/right, granted they're probably mostly just going by environmental clues.
There is research on this done in a lab with artificially generated fields AND in room that blocks out ALL outside magnetic fields including north. There's even a video on here about it. (or several.) They hook people up with EEG brainwave detectors and other brain monitoring devices. The researchers can watch people's brains react to changes in the artificial field. (Like, MOST people they test have brain reactions.) However, most people don't have any other reaction to it and don't "notice" the reaction. But, some do. Your nephew is one of the people tuned into the automatic brain reactions.. which is super cool. It's something people can automatically have, OR I think a skill they can also learn.
My wife has the ability to know when im trying to nap. If its within 200 meters of her, she can show up and give me chores that need to be done. Neat power.
We have several senses we don't learn about as kids. Temperature, time, motion... All are senses. And though you can sort of make an argument for temperature being part of touch you absolutely can't with motion and time.
I literally wait for your videos to come out every Monday, it's disappointing because I'm in the UK and I can't watch it first thing in the morning but this video was by far the funniest I've seen so far! I just love the off-the-cuff jokes and wordplay, you can't beat it
One potential advantage of cancer-detecting dogs is in rural medicine. It is much easier (cost, expertise) to maintain a dog than a CT or MRI machine. The idea would be for the dog to initially test a patient for cancer. Upon a positive result, those patients can then be transferred to the city for confirmatory test (and treatment once confirmed).
An analogy I once heard to describe how much light we can see with the human eye went like this: If all the visible light that humans could see were piano keys, we would be able to see 8 of them. The rest of the piano would stretch to the moon. That is how little light we can see. Crazy!
I need to take a moment to fully appreciate the ''your mom' joke at 1:25. The setup is perfectly concealed in a sentence that makes complete sense and thus, the mention of your giant mother is not expected. The delivery is superbly flat, and right after Joe just moves on after a cut. Such not obvious joke phrasing makes for a great effect as it takes your brain additional miliseconds until it recognizes the fact that your mother's honor has been insulted. This is as good as a 'yo mama' joke can get
I just wanted to say that I really need this today. I needed the laughs you gave me and I always enjoy the new knowledge I get from watching your videos. So thank you, Joe and team
There are dogs that are trained to detect bed bugs and although it's been disputed dogs that can detect impending seizures in people with epilepsy. I can't imagine what the world would be like with a sense of smell that strong!
The dog liked bugging bees in the yard. I tried to warn her. "No Amber!.. buggies NO ! Buggies BAD Buggies BAD " I visited my wife who had bed bugs from the moving truck. 'Amber! Get the buggie! Where the buggie"? Instantly, she put her nose right down on the nest. "Good Job. Good Job. Good Girl". Its not so hard to train them. They already know. Communication is the thing.
Was outside a week ago feeding our resident cat (long story - we “inherited” this outdoor cat from a neighbor - I agree, cats really ought to be kept inside) and there were some bats flying around the yard, eating mosquitoes (yay! go bats!)… and I was pleasantly surprised to notice that I could still hear their sonar chirps. Being in my mid-40s, that’s quite nice.
I've read in one manga, that elephants can hear better with feet than ears. Since their ears are used for thermoregulation, they aren't made to catch and direct sound. And if they want to hear something better, they press their foot towards the sound. I'm aware this was in the video, I just think it's interesting
That might have been the best delivery of a "your mom" joke I've ever heard. Struggled to pay attention to the next few minutes of the video due to excessive residual hilarity.
1:51 Technically, the shortest gamma wavelenth ever observed in nature is about 10^-20 meters and the theoretical shortest Planck-length gamma wavelength is 1.22 * 10^-28 meters. Citation, Wiki: Ultra-high-energy gamma ray PS, true infinities are rare to nonexistent in nature. For most scientists who if they observe an infinity, they recognize that there's either a flaw in their data or their knowledge is incomplete.
I have a friend at the University of Washington who has trained at least two hunting dogs to track whales! Apparently, they can detect them from tens of kilometers away. Even if they're under water.
I’ve met old hunters who found tricks to develop their own tremor sense. My uncle and his buddies used to stab Bowie knives into trees when they were hunting deer and put their ears to the pommels. If there happened to be a herd or a good sized pack of animals nearby they’d be able to feel a vibration. They weren’t superheroes, they couldn’t track a single deer from 500m by the hilt of a Bowie knife alone, but if there happened to be a large population of animals nearby it would lead them to it.
2:03 - "Luckily we got this gelatinous blob that can brainificate real good..." I actually guffawed. My coworkers are now aware that I watch UA-cam at the office, and they now watch your channel.
I actually laughed out loud from your “blood finder” joke…and then my wife gave me a look, then lovingly rolled her eyes, like she just knew I was going to find that ultra lame “dad joke” super funny! It’s not really so much that it’s that funny in of itself…but to me (and this is why I constantly bombard my wife with this kind of nonsense) it’s just so ridiculously corny that the actual utterance of them in real life is hilariously genius in its own way. And I feel that is a concept that Joe is very keen on as well! I love ur channels on here and on Nebula as well. Thanks for what you do.
Videos like this are always a great time to remind ourselves that our senses are not a direct apprehension of the objective world as it is, but the complete and total transformation of just a sliver of the phenomena around us, into a real-time hallucination playing out in our individual brains. Color and sound are internal experiences only, generated by a mind in response to external stimuli. Although they have an analog in the external world, they do not actually exist outside of the mind.
Our brains construct an entire word for us with sensory input. We are totally subject to how our brains interpret what they perceive. We truly do live in our own reality.
Joe, did ya ever come across this -> " Surprising new research is showing that birds may be able to anticipate the severity of the hurricane season ahead, months in advance. With this ability, they can adjust their schedules accordingly and potentially avoid the worst of the season when migrating south to tropical wintering grounds. "
this one of my most favourite videos from you Joe. keep going! really appreciate how you always manage to make things exciting and fun as a science channel :)
"Imagine if you could just blast sounds at someone and they could just see it" Umm.... isn't that exactly what we do when we talk to each other? A series of specific sounds from someone elicits the conceptual formation of a picture or idea in someone else's mind.
I've thought about this before: taste and smell could be considered extensions and variations of a chemical sense. Hearing (and to some extent, the kinesthetic (sense of body position) and balance) could be considered extensions of touch/tactile. Vision is an extreme case, though it could also be an extension of tactile/thermal. Another extension of tactile is barometric pressure. My sinuses often act as a barometer. An intermittently open chamber takes a reference pressure and doesn't open again for days at a time, giving a reference to what the weather is doing. I feel the pressure shift in my head long before a storm front arrives.
Most of our senses are dumbed down for general understanding, but are definitely chemoreceptors, or kinesensors. Sight is a form of radio receptor, light is a form of radio wave. I feel the barometric abilities of most animals are coincidental. Since some people dont have it, but others have fluid deposits in their bodies, like blocked sinuses, which expand or contract in presence of humidity.
Wow, thank you,Joe. I have been deaf in one ear for most of my life. I plan on researching the bone conducting headphones to see if they really work for the nerve deafness I have. You may have just changed my life!!!!! I’ll keep you updated. Grateful for you.

I swear my cats can detect what objects are lying on the table (or any other high elevated platform) and always jump onto the free space never knocking things over. Probably they are just adjusting at the last fractions of seconds while still in the jump but it always looks like they sit on the floor, look up and scan and then jump up on the free space.

My Chihuahua kept smelling my left ear. He was very persistent. When I mentioned that to my Determitologist, he noticed a small spot on my ear lobe that turned out to be melanoma. I had surgery and my dog no longer is obsessed with my ear. Good dog..🐕

The dog sniffing cancer thing would be excellent for early detection in remote communities where access to CT and other imaging equipment is very limited. Instead a team of sniffer dogs get deployed anywhere.
humans have iron in our nosess that we can use for a sense of direction. I was told that if you sleep in a north south alignment it improves your sense of direction. Orienteering people told me this.

".... blast sound at someone and they just see it"? Imagine a white wire frame 3d cube against a black background. I just did the same thing without the need for sound.
As a deaf person I can sort of describe what I would say is some form of "tremor sense." I do have cochlear implants which I wear most of the time, so my experience probably doesn't reflect that of people who have been deaf their entire lives. But when I am without my implants, I would describe it as my brain involuntarily imagining a sound I feel. In other words, an automatic reconstruction of the sound based on some kinesthetic prompt. It's definitely not like ant-man, but I can recognize the "sounds" individual people's patterns of walking make, among other simple things.
Once I had a leak in my house's water pipes, which mostly run underground - less than 30 cm. deep, but you cannot see them, they are buried. The plumber I hired to fix it, laid down on the ground and located the leak by hearing.
Something the natural compass section and the cryptochrome part made me think of: if we lack the “neurological hardware” to take advantage of our cryptochromes, could implanted technology (something like Neuralink) do it for us? Would it count as a new sense or an extension of sight? And if it counts as a new sense, would it weaken our other senses the same way lacking a new sense tends to strengthen our other senses? *edited for spelling*
My parents have a friend who is blind. When he visits them he can count the door frames between the guest room and the bathroom because the noise is different when it bounces off walls or doors (even closed doors). He also walked around their house when he visited the first time in several years and asked what the big thing in their backyard was, it hadn’t been there the last time he visited. They’d bought a caravan and he could hear the echo coming off a large object.
Yep. That's not quite echolocation/sonar (it's actually hearing the ambient resonances of the space), but even as someone who sees normally I've noticed that on occasion. The main trick is just paying more attention to the sounds around you in everyday life.
I think some people have relative superpowers. I always thought that a lot of people had a very bad sense of direction. After a while, I realised that they are normal and a few people have a very good sense of direction. I have a very good sense of direction and used to get frustrated when I had to deal with someone who had a poor sense of direction. But I have things that I'm personally quite terrible at! I don't think i have extra senses, I just think my brain processes sun direction better and my brain logs small ground features in my memory so i can use them. I am also very good at geolocation just by looking at a few photos.
I remember seeing a documentary about sperm whales where a diver swam in-front of one and held their hand to its nose, its echo location was so powerful he said it heated his hand and whole body he had to move away to avoid damaging his body. In addition the coolest thing about dolphins is their teeth are separated apart in such spacing it matches the frequency they ping out on, like how an antenna receives signal the elements are spaced in such a way they match the incoming frequency. Their entire mouth and skull is a transceiver antenna.
I suspect the dolphins tune their frequency for that purpose, rather than the other way around. The tooth spacing will change as they age, and is largely an adaptation to catch the things they bite on.
I like to think at one point humans had greater senses than we do now, some of the things we achieved all those years ago that we now just cannot fathom how they managed it.
video SO INTERESTING! a thought on dog-sniff diagnosis: as a breast cancer survivor, it was YIKES! to learn that unlike other cancers, we literally *have no way to detect breast cancer metastasis.* so you get your surgery/chemo/radiation...and then no blood test can help find metastasis for the *remainder of your liiiife* - you just have to wait till SYMPTOMS appear...by the time you have *cancer symptoms* you're in bad shape. If dogs could do semi-annual breast cancer screening, that would be HUGE.
When my kids were young I could smell the difference when they were sick and when I was pregnant with my youngest I could tell which of my coworkers was walking behind me by the way they smelled. 😳 it was bizarre
smelling when my kids were sick! i found that once that switch got turned on, it never flipped off - i can smell when any family member is sick, days before they develop symptoms. it's accurate enough that family members start taking preventative measures asap
I could detect when my Pa forgot to take his Colcheciene (I am probably spelling that wrong, but this was over fifty years ago), a medication for gout. He would get a sickening sweet smell to his sweat. I suspect it was the smell of pain? The smell would also linger after he had used the bathroom. He wondered how I knew he forgot his pill, but every time I asked, he would check, and sure enough, there was a pill in his bottle, that should have been taken with the previous meal.
I was in paramedic training and did an ER rotation where a guy came in with a dog. It was a seizure dog. It could actually sense it coming. After the guy was all set up, the dog sat and whined, the guy said he was going to have another, and a minute or so later, he sure did. It was crazy. No idea that was a thing. The guy was okay though.
There's a type of thrush called Veeries that are thought to be able to predict hurricanes. There was study and journal article by Christopher Heckscher and he found that nesting habits and number of eggs they lay are surprisingly accurate predictors of the next year's hurricane season severity.
Fun Video! Thank you! Horses. Horses being able to show eachother mental pictures. Blind horse with seeing-eye horse. AND being able to see the visualizations in your head when they are around you. Dogs. Dogs knowing when you are coming home without any clues. (including daily schedules).
Don't know about the horses (but they do have the uncanny ability of being able to hide behind themselves) but some the dog's ability to know when you are coming home, is thought to be down to the fading of your scent during the period of absence.

My mom had a mark on her arm that was pretty normal, it really only looked like a mole. My dog would sniff at it for upwards of a minute every time she saw her so I told her to get the spot looked at. She just got it biopsied and the results came back yesterday. She has Melanoma and is going to a cancer specialist next week.
She's cancer free guys! Has been for a while now. I get pinged on this post every once in a while, you guys are so sweet.
is she alright?

Was slightly surprised to not see this mentioned.. I recently saw a video online of a spider caught in a cup, and a pair of girls were trying to take a video of it with their smartphone. When they would tap on the table the spider wouldn't flinch, but every time they tried to focus on the spider by tapping their phone screen where the spider was, the spider would flinch as if it was responding to the tap directly. It was discovered that the spider was responding to the lidar or infrared signal being emitted from the phone every time it sent out a beam to focus. Apparently spiders and some other animals like deer can see this spectrum, but humans can not.
I'm gonna try that the next time i see a spider. I've tried flashing a regular light but didn't get a response.
How would I find this video about this pair of girls and a cup? LoL
@@stevechance150 very, very carefully.
Radio waves, and any form of light that way can be seen. Our eyes are nothing more than visual-wavelength radio dishes.
Its very possible if we find alien life, they could see completely different spectrums. Maybe only AM, maybe only Microwaves, maybe only Gamma waves. Assuming they see at all of course. Basically if it can be picked up through a radio dish, it can be seen by an animal with eyes tuned correctly.
And also that all radio dishes are effectively man-made eyes, more so than cameras weirdly.
@@stevechance150 you're better off searching "spider responds to lidar" lol
In the summer of 1992, my wife and I took a trip to the Florida keys. One of the events was a day at the Dolphin Research Center in Marathon Key. It was one of the most amazing experiences of my entire life (for many reasons that I won't go into here). But the most incredible thing happened when we were finally allowed to get in the water with the dolphins. They were not captive; but instead free-swim mammals that could leave out to open ocean anytime they wanted - they just liked to hang around and work with the Marine Biologists (and the visitors!). I climbed down into the lagoon first. and the dolphins came over & checked me out; splashing, "talking", etc. However, when my wife got in the water, something completely different happened...one-by-one, all the female dolphins started to gather around her in a circle; clicking incessantly. My wife started to get a little unnerved by this. The Bilologist was watching from the platform, and asked me "Is your wife pregnant?" I told her "Yes, about 5 months". She said "They know. They can see the baby. As long as she's in the water, they will not allow anything to come near her." How incredibly cool is that ?!?
INCREDIBLY COOL is how that is!! There are stories of women who work with wolf sanctuaries - and the wolves can smell when a woman is pregnant and are clearly DELIGHTED that there is a puppy on the way :D
How amazing that they can do this! Love dolphins.
@@bookmouse2719 I think they're a lot smarter than most people realize... A friend of mine is (well - was :-) a surfer from Ventura, CA. He was out one day in the early morning; surfing off the coast of Ojai. One of his friends who was on-shore started hollering at him - there was a 12 to 15' Great White on the surface of the wave just a couple yards behind him. He said his heart almost jumped out of his chest. Then out of the corner of his eye to the left, he saw 3 dorsal fins cutting across the face of the wave heading directly at him. He told me that at that point, he figured his time was up, and started praying...all while trying not to lose his balance. The 3 fins split up and swam around him on either side. When he turned to see what was going on, there were 3 dolphins heading right toward the shark. The shark broke off his pursuit, and dropped back. Two of the dolphins continued to chase it away; the third one swam alongside my friend until he reached the shore break. It lingered in the shallows for a few seconds while my (truly blessed!) pal grabbed his board and walked out of the water. Then the dolphin turned and swam off. My friend said he sat down on the sand - and cried his eyes out 15 minutes.
@@ivytarablair Puppy??? In woman? :o
That's AWESOME! I love dolphins💙🐬
my childhood dog actually found skin cancer in my dads forearm when i was growing up. Its was a spot she was fixated on and anytime he was around she would keep going back to that spot. He got checked soon after and come to find out she detected very early melanoma and basically saved my dads life because it was found so early. More so than for hospitals, i think having a dog in the home that can smell cancer is extremely valuable, I'm not sure how we would go about that but if your dog every gets fixated on a spot on your body, best to get it checked.
There are quite a few stories in this same category. I heard one about a lady whose dog kept pawing at the back of her leg, then eventually started nipping at the same spot, which finally got her to check the spot, go to the doctor, and have the melanoma removed.
@@boganvogue6694 No, the heinous attempts to make money are by the corporate healthcare providers who vigorously and relentlessly try to stomp on anything that might somehow diminish their profit margins. In the video, Joe specifically mentions an organization that is working on a standardized method of training the dogs for this task, which means your comment is obnoxiously ignorant.
@@boganvogue6694 Dogs are routinely trained for finding medical issues, so nothing stops a dog from flagging something they find off without training - They just don't have any context for what it is, they just identify something as different and are curious or concerned/irritated. But there are also plenty of properly trained personal assistant dogs who can sense different conditions, like dogs that help their owner identify blood sugar levels etc.
There's also rats that can successfully sniff out things like cancer and land mines - dogs are not unique in this.
Just because you lack all kinds of productive potential doesn't mean other animals do.
A lot of dogs are fixated on people’s crotches, but I don’t think that means there’s something wrong with those people.
If dogs have such sensitive noses, why do they need sniff each others butts from so close up, because I understand the scent of the excretion from anal glands is extremely strong.
@@kellydalstok8900 They sniff each others butts because unlike humans they have a much more complex registration and separation of scent;
The closer they are to the scent the stronger they are likely to perceive the different subtleties, so we can safely assume they get more stimuli + a clearer "image" of whatever information it brings them.
Not unlike you bringing something closer to your eyes to see more detail or get increased perception; You can see and hear your friend from 10 meters away, so why stand 1-2 meters away? Or bring a flower closer to your nose to smell for that matter.
Since dogs are notoriously bad at bringing their calling cards with them, they do the butt sniff instead, as the anal glands supposedly reveals a lot of information about the other dog to them.
There is nothing wrong with the crotches dogs sniff, there is just a lot of scent information (and the dog is unlikely to behave "strange" when doing it) - it's a bit of a weird analogy as likewise doctors talk to a lot of people around them that aren't sick.
(But if you meet a doctor that looks at your arm and remarks "you might want to get that looked at" you probably should - regardless how many healthy arms that doctor has looked at prior to it)
Echolocation Sense:
I learned the "Daniel Kish style" human passive and active echolocation (even though my vision is perfect). It is simultaneously suprisingly simple and difficult. The concept is simple: You just have to learn to interpret, single out, enhance, discard and/or focus on specific sounds. But the difficult thing is the "sound vocabulary" that you have to build up by making a tongue click at literally everything you "see". It's just like learning Chinese is theoretically simple to learn, yet you have to study and learn thousands of vocabulary words in order to understand it. I'm at an active echolocation level now where I can comfortably walk through my own rooms, dangle along a forest path without swaying to the sides too much, find my way around in rooms and buildings where I've never been before. Perfectly blindfolded, of course. I've even trained myself to interpret the sound as "images". This imaging technique can be a blessing *and* a curse because once aquired I even see sounds when I try to fall asleep.
Tremor Sense:
I'm experimenting making this sense available for humans, too. I achieve this by combining a relatively small compression spring that has a small rubber ball on the one side and a magnet on the other. Then, I attached an equally sized magnet to the base of my thumbnail. This construction allows me to put this sense on and off whenever I like. The magents are very thin and small so they usually don't bother me. Now, whenever I move my hand - and especially my thumb - the vibrations and kinetic energy gets amplified by this small self-built tremor sense as the ball oscillates on the small compression spring. It is a really weird feeling because my brain interprets the vibrations that I can newly sense now as sound. So if the self-built compression spring tremor sense swings back and forth at 5Hz I'll hear 5 Hz. The same goes for smaller and higher frequencies. The thumbnail is very sensitive and ideal for things to stick onto without irritating the skin. I'm working on a combination of differently sized compression springs on a single stick-on tremor sense construction so that I'll be able to "hear" more than just one frequency at a time.
Polarization sense:
Humans can see the polarization of light. It's called Haidinger's Brush and is located in the center of the visual field. But it is way too faint to have any practical use in day to day life. However, we can wear passive linearly polarized glasses where the left lens polarizer is rotated to 45 degrees and the right one to 135 degrees. Putting these glasses on you can see stress patterns as colored patterns in conditions where there is polarized light and/or polarized filters. And you can make out the general polarization of light in the form of (dependently monochromatic) light intensity differences. If you now wear appropriate glasses with two differently colored lenses (that don't possess a stress pattern or birefringence) you can even see this polarization in a dichromatic gradient instead of a situational monochromatic one. With the right interfernce glasses (like: Infitec's Triple Band Pass Interference Glasses) you can make the colorful stress patterns (birefringence) even way more visible, sharp and distinct AND give (monchromatic) polarized light a dichromatic gradient.
Tetrachromacy or more:
I'm working on making humans more than trichromats by bestowing a fourth cone or something similar onto them. Earlier, I mentioned Infitec's Triple Band Pass Interference Glasses (TBP glasses) that split the RGB cones in our eyes into R1G1B1 in the left and R2G2B2 in the right eye. This is achieved by the combination of multiple band pass filters in a single lens. If we take the green cone for example the TBP glasses split the cone sensitvity into two parts: The left eye now only receives a green where all the green cones that are more sensitive to red-ish light are cut off and the right eye now only receives a green where all the green cones that are sensitive to more blue-ish light are cut off. In effect, it makes 2 cones out of one. And because a lesser sensitivity of a cone type results not just in a perceived luminosity change but also in a perceived color change - because the surrounding colors shift closer in to the color space of the diminished color - you implement impossible color combinations into your vision. This happens to all three cone types and enables you to make out color differences you could have never imagined being able to differentiate before. Unfortunately, you won't see any new "primary" color. However, I feel like I can see new secondary and tertiary colors / color differences.
With only a single magenta lens over one of my eyes I calculated that I can even see at least 1.25 times the colors (especially in the yellow-green/lime and cyan-green/turquoise color space). Wearing this single magenta lens allows me to make out double the color differences in the lime and turquoise color space. So where the green to greenish-lime colors #00FF00 and #20FF00 look identical to me under normal conditions, with the single magenta lens on these two colors are as different to me as #00FF00 and #40FF00 (where I can normally see a slight difference). So this an increase in color discriminability from 40 down to 20, that is double the color discriminability. I can make out details in cyan to yellow things I could have never noticed before, even (and especially) on RGB screens. Yellow is as different from green to me now as red is from green. And red glows like a beacon. My subjective color contrasts are definitely a lot higher.
And this is only the beginning. I'm working an active XR glasses and software (the glasses I mentioned before are all passive) that implement impossible colors into the perceived color spectrum. So like a red-orange, a red-yellow, a red-lime, red-green, a magenta-green, a cyan-red, a green-purple, etc. With this technology you can implement at least 155 new distinct (impossible) color combinations into your color spectrum. And oh boy, I've already seen it. The camera and color pass through quality of the XR glasses I used were abysmally bad and yet it was so beautiful. You can imagine what I saw with it like Star Trek's Geordi La Forge's VISOR. (There are clips online that show what he'd see. It was in an offical episode.) There is color in color in color in color and it's not an exaggeration. If you can learn to make sense of this even tetrachromacy seems inferior.
As you might tell, I'm a sense researcher. I love senses because they are the only things that connect us to this world. If you can sense more of this world by acquiring more senses or enhance the already existing ones, this world will become even more beautiful and rich in detail.
All of that is very interesting, do you have a blog or other resources to learn more?
@@r0cketplumber I have relatively recently made a new English UA-cam channel named "Ooqui" were I (inconsistently) post a 5 to 15 minute long video on the topic of "human senses" and how to enhance them. Until now, I've only made videos on enhancing color vision. But videos on human echolocation, tremor senses, polarization senses and more tetrachromacy will come eventually, too. On this here channel I write this comment with I've also made videos on enhancing human senses. However, these videos are in German and you'll most likely won't understand it. I don't have a blog, yet. But maybe soon. Other resources are difficult to provide because some of the things I learned are by experience and yet not studied enough. At least in the way I use them, as I tend to methodically and deliberately misuse ordinary things to turn them into new sensory experiences.
This was very interesting, thankyou!
Sensory augmentation is something that has fascinated me since I first grokked it. It’s rare to hear about this sort of thing from legitimate researchers. A couple of years ago I got all excited about the idea of sticking magnets under the skin on my fingers but the materials and processes were far from perfect and potentially dangerous. Sorry to upset the grinder/bio hacking community but I think non invasive methods are the way forward.
@@frankdaze2353 I wouldn't call myself a "legitimate" researcher. However, I am very passionate about sensory augmentation and everything that comes along with it. In my opinion non-invasive methods of sonsory enhancement/augmentation is definitely the safer method. You could theoretically achieve a higher degree and quality of sensory augmentation via invasive methods but the risks are higher the more invasive the method becomes. I am personally focussing on non-invasive methods because they are more easy to achieve with a small budget, because they are safer, and because they are less permanent and thereby much more adjustable/configurable. If you implant a magnet inside of you finger tip you can't easily iterate and update the "version" of that magnet. If the magnet however is placed on top of the finger nail, for example, you can take it on and off anytime you like without much pain involved. That's also why I favor glasses over contact lenses in general. The option to turn a new sense on and off in extremely valuable.
Electric Eels - you missed those.
Electric Eels can move forwards and backwards, without contacting anything, even in sediment-filled opaque water. They create an electric field around their body that enables them to sense what's around them through their skin.
It's a bit like echo-location only using electricity rather than sound.
I think thats just advanced electrosense. Its pretty much what sharks do but cranked to 11.
Wow, that's pretty cool
Electro-location?
@@pauldeddens5349 I don't believe sharks produce their own electricity though; they sense electricity created by other things like the muscle contractions of fish or boat motors. Electric eels produce their own electricity and use it to kill their prey, and unfortunately the occasional person or horse (supposedly a gaucho crossing a river in South America perished this way). They also use different muscles to create different voltages depending on their goal (searching/hunting, stunning/killing, or communicating).
@@RyanDugan23 I thought sharks produced a very small current in order to find prey, like shining a flashlight. Though it is possible they just find ambient current in the water, i dont know.
I remember watching a news report years ago where a cat in a nursing home could sense the pending death of a patient. The cat was so accurate that the people working there notified the next of kin so they can make one last visit.

How about the dogs who are able to smell high sugar levels in Type 1 Diabetics, or the cat in the rest home who was able to tell when one of the patients was about to die, this was documented in over 100 cases. Animals are amazing! Thanks for sharing
I'm type 1 diabetic, and my cat has forcefully woken me up if my blood sugar crashes while I'm asleep. He's probably saved my life several times already.
Dogs can also detect if someone is about to pass out or about to have a panic attack.
I was a Dog Trainer for the U.S. Navy. For the most part I trained bomb,drug and cadaver dogs. When it comes to how dog's smell, the amazing part is their ability to distinguish each of these scents. An easy way to explain it is, when you pull up to a McDonalds, you smell food. A dog smells, beef, bread, catsup, mustard, potatoes, oil etc.. they can distinguish each ingredient. This is of course is how they find your "drugs" when they are encased in things like coffee or whatever you "try" to hide your drugs in. It's the same with human remains, even with all the other scents in the air, they break them all down and ignore what they are not trained to look for. It is really amazing.

All dogs have two incredible superpowers that you didn't mention. The first is the ability to spread out and occupy all the surface of any human's bed, and do it silently while you are asleep. The second is an exponential increase in the gravity affecting the hind end of the dog whenever the words "go to the vet" are spoken or spelled out. The butt of a thirty pound dog will weigh more than ninety pounds once the phrase is uttered.
I think you're a magician, sir.
They also have an internal chronometer so they always know when it’s supper time and treat time. This is a gift cats also possess.
Combined with their inability "drop the ball" and their ability to respond to "what's in our mouth?" with various evolutionary avoidance tactics, I believe this makes dogs the most interesting creatures on the list.

they can also hear a bag crinkle from 3 miles away and hit you with horrendous farts when you least expect it.
Regarding echolocation by blind people, I remember seeing a programme where a young blind guy was using just that to get around and was refusing to use a cane. Another blind person showed him that echolocation wouldn't let him know if there was a hole in the road in front of him, whereas a cane would have warned him that the ground wasn't solid ahead of him.
Also it's not precise since it can't properly distinguish these barriers. For example a pole verses many forming a fence. In crowded places people will register woefully awfully, animals, cars, moving momentary barriers.
Source? I'm a blind person. I had a device doing it coz I have a bit of hearing loss too and it'd vibrate depending on distance and barrier. Kept sleeping off steps, gutters or bumps. I kept going round non-existence barriers or "seeing" a crowded street like a wall.
And isn't that hearing finger movement universal, I mean it sounds different. Worst feeling is nail over rough brown braille paper.
A scorpion has tremorsense and others but also a UV sensor in their tail that acts like an eye - it detects if the scorpion itself is in light

@@CBEnoddyy You are full of ------. We can echo location, hear with our feet, just a dog tell smells with our nose, and some of ours can see magnetic line of force! And it proven all the back to the 60s.
As someone who has recently become visually impaired, I find it quite inspiring to learn about how are people have managed to sharpen their other senses in order to compensate. I have certainly noticed that I pay a lot greater attention to my sense of touch and for example use it to properly orientate my clothing when folding or getting dressed in a way that was very difficult when this first happened to me.
in my opinion the mantis shrimp is one of the weirdest but coolest Animal to existed, because it has 12 color cones (16 in some reports), which means they can see both ultraviolet and infrared.
they also hit the hardest of any living creature because, their club like arm accelerates faster than a bullet out of a gun, which can break through shells.
Also polarisation! Cool critters.
This one still blows my mind ever since I heard about it.
It does make you wonder why a shrimp would have some of the most advanced eyes on the planet?
@@alphagt62 Technically its in its own group, between lobsters and shrimp. Just visually resembles a shrimp.
Current ideas focus around sociality, territoriality, and hunting.
They are social creatures, who appear to communicate using UV (Or IR, its one of the wavelengths just beyond visible light), and using their iridescent paddles next to their heads, can reflect or alter the signal, as a response.
They are also very territorial, and will generally obliterate anything that comes near its dens. A spotless den means a strong, evolutionarily fit mantis shrimp.
And hunting, its hard to camouflage when you see that many spectrums of light. Most creatures sneak in predators blind spots by signaling with one spectrum or another. Like how many insects, fish, and even mammals glow under UV light. Seeing all of those wavelengths makes it easier to spot intruders into their dens, and hunt creatures hiding in sand and camouflaging among rock and plant.
Why it needs 3 "pupils" is beyond me. Its not like they really could hunt three things at the same time. Maybe to keep an eye on opposing mantis shrimp, potentially during a mating season? I dont know enough about them.
@@pauldeddens5349 Maybe so they can focus vision across multiple spectra to make overlays of the thing they are focusing on. Pupils are focal points, so multi specrta layering when focusing on something.
I used to be a Sonar Tech in the Navy, and our man-made sonar works the same way as the bat's ears. The transducer switches between a "transmit" mode, where it can emit sound but can't hear, to a "receive" mode, where it can hear but not transmit so that it doesn't "blind" itself with every transmission. The stuff about "telepathy" in dolphins got me thinking about a couple of things though, as this same sort of "telepathy" is how I learned to "echolocate". By that I mean looked at an listened to subs recorded by people who had seen them before, figuring out what their diagnostic features were and learning to ID real ones in the wild. I imagine that dolphins would probably teach their children to hunt in a similar way. Of course, most of my own training didn't involve listening to recorded pings bouncing off of subs. Finding something you are screaming at is actually pretty easy so you don't have to spend much time on it. The vast majority of my own training revolved around detecting subs "passively", that is, just listening and and figuring out what it is you are looking at before you turn on that loud ass sonar that will give away your position. For every one hour I spent practicing at tagging and tracking active contacts, I probably spent 4 working through "grams", recordings of known subs that you have to ID based on the frequencies they emit. Bonus points if you can get range, bearing, course, and speed information from the gram. I imagine that there would be similar pressures on animals like dolphins, who would probably listen for the sounds of a school of fish before focusing their sonar on a known location, rather than clicking away using active search and scaring away all the fish. One good way to see if dolphins are teaching one another or transmitting information by mimicking the returned clicks from a given piece of stimuli may be to see if they are doing this for other, stranger sounds. Do dolphins ever mimic the tailbeats of a school of fish or the staticky clicking of a school of shrimp? I'd be interested to see if mother dolphins are mimicking very undolphinlike sounds to teach their children what prey sounds like.
That was truly interesting. Thanks for sharing!
Getting to hang out with the doggos would be a lot more pleasant than getting put in a CT scanner. That's for sure!

The monarch butterfly is a good one. It's able to follow the migration flight patterns of distant ancestors skipping over generations who have never been on that trip.
In regards to using sound to determine structural integrity:
I used to work on tanker ships that transport fuel for the Navy. We would always clean the tanks before we entered a shipyard for repairs. One of the times I thought it was very cool that the company occasionally hires experienced climbers to climb around in the tanks "sounding" the different parts of the metal structures to make sure the metal hasn't thinned to the point of needing to be replaced.
Extra related info: A big part of my job was removing rust from the metal and painting over it. This is a big contributor to the thinning of the metal.
You had a cool job!👍

To be clear, the painting over the removed rust was to prevent further rust with an anti-rusting paint.

I hit the pause button! I've never considered this before but whenever I yawn, I go completely deaf. I never thought of it as a mute button before. I like that! Special at last....
Heat sense... I remember taking a welding class in HS, and reaching towards something, and feeling that radiant heat, knowing it was about to hurt, but could not react fast enough to stop. I'll always remember how weird it was knowing that it was going to hurt, but being unable to do anything about it because it was so fast.
Yeah it's amazing how fast the brain is able to interpret impending events but the rest of the body can't react quick enough and when you think back on it it's like it happened in slow motion. I was a passenger in in a car going 55 mph that was approaching an intersection with a green light and I saw a car to my left run a red light and realized we were going to T-Bone it so i instinctively put my feet on the dash (bad idea- never do this!) as I tried to warn the driver but all that came out was "OH OH OH!" and WHAM! Everyone was okay except for minor injuries. One of my feet went through the windshield and the other foot went down below the dash as I flew forward because I had the automatic shoulder belt on but not the lap belt and the shoulder belt didnt lock immediately so I flew forward and when it locked it was like getting hit with a sledge hammer and cracked my chest plate. Good thing we didn't have passenger side airbags or it would've certainly broke my feet and legs. Good times!
@@birdflipper oof!

Years ago I worked in a large photographic lab. Part of that was a blacked out corridor that went from six printing darkrooms to two paper processors. Two or three of us would be working in that area at the same time. We never collided with each other untill there was a cold going round that muffled our hearing, we had to start calling out to each other to avoid collisions.
Solpugids (sun spiders, camel spiders, wind scorpions) have unusual sense organs on the undersides of one pair of legs. Last I heard, no one has yet figured them out.
I've watched the way they move and run. Very different movement patterns. Something different is going on with the way they are sensing.
They often move like a leaf that has suddenly dislodged from a snag in a strong wind, and then travels five or ten feet and hits another snag, and suddenly freezes. Then it happens again, sometimes with a change in direction.
They move fast and suddenly. They are apparently the fastest land arachnids.
I didn't need that. I didn't need that mental image. We don't even have scorpions here, but I'm imagining seeing a scorpion and it making a dash up my leg. Oh shit! 🦂
@@stevechance150 If they get caught out in the sun, they will run towards shade. They don't seem to care how much shade just as long as there is shade. Including the shade we produce.

The first time I saw one, I was walking up a hill in the dark, on a trail. I had a flashlight, and saw it in the middle of the trail just in front of me. It froze in the light. It looked strange at first, like a tarantula, but not like a tarantula. I bent down and kept the light on it. Then it no longer looked strange, it looked exceedingly strange. I thought I knew all the local life forms pretty well. This was like some alien with ten legs. It freaked me out. These things are scary looking.

Here’s an odd one. My 10 year old nephew when visiting us a couple hours away from home had the ability to feel what direction north was… I tested him left and right (made sure to check at noon when Sun was above, no device or car queues present, etc) but he was 💯 accurate each time I’d ask. To this day he doesn’t know why/how but has an innate sense - only explanation I could find was a rare ability to feel magnetic fields (sounds crazy, I know).
Also, he travelled mainly SW to get here, and I would make a point to take confusing winding roads (sneakily) and then suddenly ask where north was. He wouldn’t think but 1-2 seconds before pointing. Super bizarre
not that out there, there's at least one tribe that uses cardinal directions instead of left/right, granted they're probably mostly just going by environmental clues.
Supposedly, Aborigines do it. There's an answers with joe video about five weird language phenomena where he explains it.
There is research on this done in a lab with artificially generated fields AND in room that blocks out ALL outside magnetic fields including north. There's even a video on here about it. (or several.)
They hook people up with EEG brainwave detectors and other brain monitoring devices. The researchers can watch people's brains react to changes in the artificial field. (Like, MOST people they test have brain reactions.)
However, most people don't have any other reaction to it and don't "notice" the reaction.
But, some do.
Your nephew is one of the people tuned into the automatic brain reactions.. which is super cool.
It's something people can automatically have, OR I think a skill they can also learn.
Not crazy at all, I do that too. 😃
There are service dogs trained to sense seizures, diabetic conditions, anaphylaxis, and a few others.
My wife has the ability to know when im trying to nap. If its within 200 meters of her, she can show up and give me chores that need to be done. Neat power.

We have several senses we don't learn about as kids. Temperature, time, motion... All are senses. And though you can sort of make an argument for temperature being part of touch you absolutely can't with motion and time.

One potential advantage of cancer-detecting dogs is in rural medicine. It is much easier (cost, expertise) to maintain a dog than a CT or MRI machine. The idea would be for the dog to initially test a patient for cancer. Upon a positive result, those patients can then be transferred to the city for confirmatory test (and treatment once confirmed).
An analogy I once heard to describe how much light we can see with the human eye went like this: If all the visible light that humans could see were piano keys, we would be able to see 8 of them. The rest of the piano would stretch to the moon. That is how little light we can see.
Crazy!
Its because people love to forget that all radio waves are a form of light. It just so happens we evolved to have eyes tuned to this radio spectrum.
I need to take a moment to fully appreciate the ''your mom' joke at 1:25. The setup is perfectly concealed in a sentence that makes complete sense and thus, the mention of your giant mother is not expected. The delivery is superbly flat, and right after Joe just moves on after a cut. Such not obvious joke phrasing makes for a great effect as it takes your brain additional miliseconds until it recognizes the fact that your mother's honor has been insulted. This is as good as a 'yo mama' joke can get
I just wanted to say that I really need this today. I needed the laughs you gave me and I always enjoy the new knowledge I get from watching your videos. So thank you, Joe and team
There are dogs that are trained to detect bed bugs and although it's been disputed dogs that can detect impending seizures in people with epilepsy. I can't imagine what the world would be like with a sense of smell that strong!
The dog liked bugging bees in the yard. I tried to warn her.
"No Amber!.. buggies NO ! Buggies BAD Buggies BAD "
I visited my wife who had bed bugs from the moving truck.
'Amber! Get the buggie! Where the buggie"?
Instantly, she put her nose right down on the nest. "Good Job. Good Job. Good Girl".
Its not so hard to train them. They already know. Communication is the thing.
Was outside a week ago feeding our resident cat (long story - we “inherited” this outdoor cat from a neighbor - I agree, cats really ought to be kept inside) and there were some bats flying around the yard, eating mosquitoes (yay! go bats!)… and I was pleasantly surprised to notice that I could still hear their sonar chirps. Being in my mid-40s, that’s quite nice.
I've read in one manga, that elephants can hear better with feet than ears. Since their ears are used for thermoregulation, they aren't made to catch and direct sound. And if they want to hear something better, they press their foot towards the sound.
I'm aware this was in the video, I just think it's interesting

I’ve met old hunters who found tricks to develop their own tremor sense. My uncle and his buddies used to stab Bowie knives into trees when they were hunting deer and put their ears to the pommels. If there happened to be a herd or a good sized pack of animals nearby they’d be able to feel a vibration. They weren’t superheroes, they couldn’t track a single deer from 500m by the hilt of a Bowie knife alone, but if there happened to be a large population of animals nearby it would lead them to it.

Videos like this are always a great time to remind ourselves that our senses are not a direct apprehension of the objective world as it is, but the complete and total transformation of just a sliver of the phenomena around us, into a real-time hallucination playing out in our individual brains. Color and sound are internal experiences only, generated by a mind in response to external stimuli. Although they have an analog in the external world, they do not actually exist outside of the mind.
Our brains construct an entire word for us with sensory input. We are totally subject to how our brains interpret what they perceive. We truly do live in our own reality.
Spiders and spiderlings can sense the right time to fly (via "ballooning") by means of electric potential differences.
Joe, did ya ever come across this ->
" Surprising new research is showing that birds may be able to anticipate the severity of the hurricane season ahead, months in advance. With this ability, they can adjust their schedules accordingly and potentially avoid the worst of the season when migrating south to tropical wintering grounds. "
In some places where landmines are a problem, bees are trained to detect the chemicals released by the mine's explosives and flag their locations.
Also, planaria; the flatworms. You can cut them in half and the part without a head “remembers” things.

Wow. Thats one of your better episode. So many new interesting things. Keep going!
"Imagine if you could just blast sounds at someone and they could just see it"
Umm.... isn't that exactly what we do when we talk to each other?
A series of specific sounds from someone elicits the conceptual formation of a picture or idea in someone else's mind.
I've thought about this before: taste and smell could be considered extensions and variations of a chemical sense. Hearing (and to some extent, the kinesthetic (sense of body position) and balance) could be considered extensions of touch/tactile. Vision is an extreme case, though it could also be an extension of tactile/thermal.
Another extension of tactile is barometric pressure. My sinuses often act as a barometer. An intermittently open chamber takes a reference pressure and doesn't open again for days at a time, giving a reference to what the weather is doing. I feel the pressure shift in my head long before a storm front arrives.
Most of our senses are dumbed down for general understanding, but are definitely chemoreceptors, or kinesensors. Sight is a form of radio receptor, light is a form of radio wave.
I feel the barometric abilities of most animals are coincidental. Since some people dont have it, but others have fluid deposits in their bodies, like blocked sinuses, which expand or contract in presence of humidity.

The dog sniffing cancer thing would be excellent for early detection in remote communities where access to CT and other imaging equipment is very limited. Instead a team of sniffer dogs get deployed anywhere.

As a deaf person I can sort of describe what I would say is some form of "tremor sense." I do have cochlear implants which I wear most of the time, so my experience probably doesn't reflect that of people who have been deaf their entire lives.
But when I am without my implants, I would describe it as my brain involuntarily imagining a sound I feel. In other words, an automatic reconstruction of the sound based on some kinesthetic prompt. It's definitely not like ant-man, but I can recognize the "sounds" individual people's patterns of walking make, among other simple things.

Hello how are you doing 😊
Something the natural compass section and the cryptochrome part made me think of: if we lack the “neurological hardware” to take advantage of our cryptochromes, could implanted technology (something like Neuralink) do it for us? Would it count as a new sense or an extension of sight? And if it counts as a new sense, would it weaken our other senses the same way lacking a new sense tends to strengthen our other senses?

My parents have a friend who is blind. When he visits them he can count the door frames between the guest room and the bathroom because the noise is different when it bounces off walls or doors (even closed doors). He also walked around their house when he visited the first time in several years and asked what the big thing in their backyard was, it hadn’t been there the last time he visited. They’d bought a caravan and he could hear the echo coming off a large object.
Yep. That's not quite echolocation/sonar (it's actually hearing the ambient resonances of the space), but even as someone who sees normally I've noticed that on occasion. The main trick is just paying more attention to the sounds around you in everyday life.

Dolphins communicating with sound isn't telepathy, it's talking.
I think some people have relative superpowers. I always thought that a lot of people had a very bad sense of direction. After a while, I realised that they are normal and a few people have a very good sense of direction. I have a very good sense of direction and used to get frustrated when I had to deal with someone who had a poor sense of direction. But I have things that I'm personally quite terrible at! I don't think i have extra senses, I just think my brain processes sun direction better and my brain logs small ground features in my memory so i can use them. I am also very good at geolocation just by looking at a few photos.

In addition the coolest thing about dolphins is their teeth are separated apart in such spacing it matches the frequency they ping out on, like how an antenna receives signal the elements are spaced in such a way they match the incoming frequency. Their entire mouth and skull is a transceiver antenna.
I suspect the dolphins tune their frequency for that purpose, rather than the other way around. The tooth spacing will change as they age, and is largely an adaptation to catch the things they bite on.

I really appreciate your channel Joe. Thank you helping me to brainificate this morning. 🙏
Brainificate added to my daily vocabulary.
I laughed so loud at the mom joke I got stares from the rest of the coffee shop. Thank you for giving me, and them, a story.
I like to think at one point humans had greater senses than we do now, some of the things we achieved all those years ago that we now just cannot fathom how they managed it.
video SO INTERESTING! a thought on dog-sniff diagnosis: as a breast cancer survivor, it was YIKES! to learn that unlike other cancers, we literally *have no way to detect breast cancer metastasis.* so you get your surgery/chemo/radiation...and then no blood test can help find metastasis for the *remainder of your liiiife* - you just have to wait till SYMPTOMS appear...by the time you have *cancer symptoms* you're in bad shape. If dogs could do semi-annual breast cancer screening, that would be HUGE.
When my kids were young I could smell the difference when they were sick and when I was pregnant with my youngest I could tell which of my coworkers was walking behind me by the way they smelled. 😳 it was bizarre
I can detect smokers (when they are not smoking), or people that are ill. My nose tickles when their breath is directed towards me.
smelling when my kids were sick! i found that once that switch got turned on, it never flipped off - i can smell when any family member is sick, days before they develop symptoms. it's accurate enough that family members start taking preventative measures asap
I could detect when my Pa forgot to take his Colcheciene (I am probably spelling that wrong, but this was over fifty years ago), a medication for gout. He would get a sickening sweet smell to his sweat. I suspect it was the smell of pain? The smell would also linger after he had used the bathroom. He wondered how I knew he forgot his pill, but every time I asked, he would check, and sure enough, there was a pill in his bottle, that should have been taken with the previous meal.
I was in paramedic training and did an ER rotation where a guy came in with a dog. It was a seizure dog. It could actually sense it coming. After the guy was all set up, the dog sat and whined, the guy said he was going to have another, and a minute or so later, he sure did. It was crazy. No idea that was a thing. The guy was okay though.
I knew about the shark stuff, but not about some of the rest. Thank you for informing us of all that!
Love the Tangent Cam - I need that in real-time when talking to anyone
I can sense when it’s raining and flounders cannot. I win.
There's a type of thrush called Veeries that are thought to be able to predict hurricanes. There was study and journal article by Christopher Heckscher and he found that nesting habits and number of eggs they lay are surprisingly accurate predictors of the next year's hurricane season severity.
Hello 👋 How are you doing today??
I always wondered how Narwhales travelled under the ice, only coming up in some spots, and how they did that without risking drowning.
Hello 👋 How are you doing??
Fun Video! Thank you! Horses. Horses being able to show eachother mental pictures. Blind horse with seeing-eye horse. AND being able to see the visualizations in your head when they are around you. Dogs. Dogs knowing when you are coming home without any clues. (including daily schedules).
Don't know about the horses (but they do have the uncanny ability of being able to hide behind themselves) but some the dog's ability to know when you are coming home, is thought to be down to the fading of your scent during the period of absence.
