- Deep at the bottom of the Pacific Ocean, an amazing bacterial discovery reshaped our view of life on earth.

Archaea 101: / microbes-101-archaea
In 1977, three people squeezed into a sturdy little submersible named “Alvin” and dived 7,500 feet to the bottom of the Pacific. The team was looking for something that had been predicted for years but had never actually been seen: deep-sea hydrothermal vents. These jets of volcanically superheated water would be caused by two continental plates pulling away from each other on the ocean floor. The Alvin crew found the vents, but they also saw something else that took them completely by surprise. They had expected a barren sunless world on the ocean floor, but instead found one that teemed with life-a menagerie that included the giant tubeworm, Riftia pachyptila, that can grow taller than a person.
In this episode, Ed talks to Colleen Cavanaugh and finds out how the tubeworm can live in complete darkness and, more curiously, without even having a mouth or anus. In a process called chemosynthesis, symbiotic bacteria inside the tubeworm use hydrogen sulfide spewed from the vents as an energy source for themselves and for the worms. An entire unexpected ecosystem powered by chemosynthesis thrives in the dark depths of the ocean.

We love dreaming about outer space, but sometimes we forget about this "unearthly" frontier all around us! Thanks for another great video!
bacturiaaaaa
kkk
@@ElectronicHits you racist fish stick lol
The world is so disillusioned they would never spend the money for ocean exploration so stuck on how to get to mars to start terra forming the fact is they will have to actually work n spend money on actual tech n we will expect certain results understanding the physics and biology of this planet where as space is such an unknown frontier they can make shit up left n right sinking are wallets to an ocean that won't be explored unless there was something of materialistic value to them who knows for certain what space is seems to me I get more truth from a psychonaut then a astronaut

This video is absolutely perfect for my middle school students!! Just had to say that this was such a high-quality and enjoyable learning tool.
"Cool creatures" - "It's actually very warm"
What a charming response! Great video!
Your videos bring art and science together providing enjoyable education. Thank you for creativity and more importantly your willingness to share of yourself. Please keep doing what you do so well.
Sweet video! I love how, by pure luck, this guy was asked to speak at Harvard and a the right student just happenedto be at the right place at the right time
It's hard to find well-produced, modern videos about chemosynthesis. Excellent work. Great details. Amazing that these were only discovered a few decades ago.
nice video... I wish all educational videos were this awesome
That's why I'm a tube worm main.
I like your political compass, comrade.
everything about exploration dominated my curiosity at 11 years old when this was happening; it was world breaking; the discovery of the ecosystem and the way life persisted against all odds in a completely unexpected place - it directly leads to extremophile research since.
Very high quality content, I am stupefied . Kudos !
its times like these where i wish i could just pull up a transcript, read it, and not have to watch the video so I can do my homework
Spectacular video, very entertaining and at the same time educational... The host did a great job explaining as well!!!
Amazing video. Great execution of knowledge.
Found this video by accident, really nice, I learnt something today, thanks :)
*continues existing*
this not only explains about life on earth, but also how life adapts to all conditions on all planets, and stars, and what have you.
This video is so amazingly well made.
Great video. Loved your presentation. Clear, interesting and informative. Thank you.
Love this video. Informative and humorous
And people dreaming with mars...
great video. Thank you.
Why do the tube worms move? It's not like they need to catch the sulphur right? If they're anchored they can't exactly get anywhere.
I have an odd fascination for tube worms. Fascinating creatures.
Thanks for your hard work people!!!!
Bruh why am I watching the biology school quarantine vids late at night. I could be playing call of duty or making vids right now. :(
That was very interesting. Thank you!
everything on this channel is soo cool!
this is insanely high quality
What an odyssey ¡¡ Amazing creatures those Tube Worms ¡¡ 🙏🕉
That was very interesting, now I want to find out more about chemosynthesis. At the end there is mentioned an article with more detailed information. Can someone help me find the link?
Damn he rekt her with that eye-roll at the end there...
But how did they get DOWN There ? It's a long trip down, and not much to feed on, and no light for a long . . . long trip down... :-O ?
THIS IS SO GOOOOD!!!
Nice job!
Why do the symbiotic bacteria stop oxidizing H2S at S8? Why not go to H2SO4 and get more energy?
That is written in the Bible
“In hell, the worms do not die, and the fire never goes out." -Mark 9:48
Hell is in the heart of earth.
Thank you very much 🙏🙏
Awesomly interesting ! :D
would this relationship be chemoheterotropy or chemoautotropy?
i love his ears
Waao .. amazing video👍
what is the recognition between worm and bacteria?
But in the absence of Photosynthesis, How does Oxygen reach there?
Guy sounds just like Jimmy Carr
Very cool! Thanks!
actually, it's very warm
Awesome
Here from school
That was an amazing video besides the scientific content.
bruh

@@lindseygunderloy9422 Lol,that comment was when I was pretty "Pharisitical". Now,I try and take a more passive approach when presenting The Gospel. But I Highly recommend that channel called A Voice In The Desert,even if you don't believe in God,you may agree with what they say. I linked some of his videos in the last comment
God bless you
You're awesome!
Is that bacterial called Archaea to help digest?
very nice
I love the ocean hope to make my job partly to do with it coastal kid for life a true OG of the highest degree forgive the weed pun
How do you cook them vent shrimp
Awesomeeeeeeeeee
Yeah, WHERE IS THE TRANSITIONAL?
Colleen rocks!
Sorry. I don't buy the entire pressure theory of the weight of the water. At the bottom, the pressure is equalized in all directions. So, it's ok to live in such environment with such pressure. Just humans and other organisms that has certain elements in the blood bubbles in high pressure cannot live there.
You sound so dumb rn
Tell me the life span of this worm . You cannot , its beyond the science I challenging you ....
Hello guys I'm from the class
Are these worms indigenous?
The Worms tube worms giant worms
Sir, how do the organism survive with high pressure?
they don't listen to society
im from 2020
MORREEEEEEE
God was able to solve any and all earth-challenges to his earthly creation of life. I'd like to see a good temperature chart/diagram of the temperatures of the water all around vents. It's like sleeping in the warm area around a campfire. Too close and your sleeping bag catches fire, too far and you shiver. The sides of the vents may be cool as the large amounts of cold water rushing up the sides may create a habitation zone.
this is so fake stop the cap
science doesnt lie my little youngling, listen to the video silly dumpling
magnets how tf do they work?!
Some interesting information but the cheekiness of the presentation is mentally draining. I hope PBS considers this comment. Listeners need to always be on guard for the next pun around the corner.
shut your handsome face
remind me why that's a bad thing? most ppl like puns ya know...
who is here because of school?
