    I'm wondering, if we can make some kind of organic polymer, with a backbone, holding some kind of base capable of making H-bonds with the major groove of DNA base pair in one side of the alpha carbom, and some organic groups akin to those used in organic electronics in another, such that for different base-pair, these organo-electronic group will conduct slightly different voltage. In such a case, we can actually retirve information from DNA regularly. We might be able to address each base-pair just like each memory cell is addressed in RAM. The long polymer wrapped around DNA might slow down DNA degradation even further.

    I wonder what would happen if we ran a dataset of sperm whale conversations through a transformer (the architecture behind chatgpt). Surprisingly they can be trained without knowing the meaning of the words and even if would be inefficient, just phonemes should also work. The end result wouldn't be a translator but a chatgpt for whales, we wouldn't know what it is saying but it could be a step towards that. If it worked we could try another experiment that is a much longer shot, training another one but forcing it to shoehorn whale speak into the same embeddings as human speech and looking for similar clusters or even straight training one system to do both and hoping that it somehow learns to translate (for that to work, whale speech would need to be conceptually similar to human speech).

    Raised with a great deal of exposure to Native American culture, I have always believed that if we were so smart, we should be able to learn their languages WAY easier than we can teach them ours. I currently speak a bit of cat and dog. I have found that most living creatures (average humans excepted) are naturally capable of understanding the languages of compassion and cruelty. Interspecies communication has already been demonstrated in the wild between dolphins and gray whales, leaving me to agree with the dolphin assessment of relative human intelligence. I refuse to keep pets (as they in my lowly opinion are just a form of slavery). I do however have animal friends. Just 3 days ago I had a rescue cat walk into my apartment desperately seeking SOMEthing. Now... given an open door, she usually opts for inside rather than out. From some of her behaviors I suspect that life before might not have been so great for her. The creature sitting on my desk having a lovely, peaceful look out the window seems a far cry from the howling ghost scouring the neighborhood for about a week before we actually met. How did we meet? For several days I heard a pitiful cry moving quickly around the neighborhood (late in the evenings). At first I thought... horny cat on the prowl. But that didn't sound quite right, so I answered back. I guess she didn't hear me the 1st few tries. Then Fri. morn (after a few nights of this) I hear that voice again,. and it sounds like it's coming from my front door...I expected to see a flash streak away when I opened the door... nothing... but I gave my cat greeting, and suddenly there in from of me yowling away like a madcat was this tan-white pathetic creature, looking for attention from... anyone. I let her inside. Howling the whole time, going from room to room, she seemed most desperate when she got to the bathtub, and started swiping at the tap, so I turned the water on a bit. Yup. so I filled up a cup and held and petted her while she drank her fill. OK.. Hungry too? All I have is bit of Chicken?... no Bacon?.... no hmmm.. can of tuna? GIMMIE GIMMIE GIMMIE GIMMIE. For my part, I am more than happy to sacrifice some of my modest means to ensure that this small miracle has all the shelter, sustenance, love, and respect I can provide. She is my friend, and together for now, we will walk down the road of life. If she should decide some day to move on, she is free to do so of her own volition. Strange, that until that moment, I hadn't realized just how lonely I had become myself in the last few years (elderly, retired, and broken). "My shoes are too tight... and I have forgotten how to dance." - Londo Molari, Baylon 5 Time to remember to dance! 🤟😁👍 P.S. Now that she is starting to groom again, most of the tan has gone away leaving a snow white kitten underneath. She is starting to establish patrol routes and training me in my expected duties😉 She also still seems to prefer drinking from the running faucet than a dish. One of those odd behaviors I was telling you about.

    Several reasons, 1st. Lion fish have been super attractive as an exotic species in the pet trade. People added the fish to their tanks and they the fish ate all their fish. They dispose they fish alive in local waterways and canals. 2. They can actually live in fresh waters as well. Recently discovered which is a huge threat. 3. It's possible if not plausible that it's intentionally done to disrupt fishing industries.

    There are American biologists attempting to introduce lionfish into the food chain by training predator species. Sharks spit them out as other species that eat their prey whole. Lionfish dorsal spines defy the gaping maw predators. On the other hand , corral crunchers did better as they shred using their elongated armored mouth and are capable of attacking weak spots.

    The lionfish is specialized in eating frye, basically whatever eats them will have their young eaten just because they overlap as breeders beneath the reef. which is to say as they lay their eggs they are preyed apon by larger fish at depths beneath the reefs. but go on to eat every single frye of those predators as a they hatch.

    • @DeLevely
      @DeLevely Місяць тому

      Apparently lionfish have been documented at depths of up to 300m, and female lionfish can release tens of thousands of eggs in a single spawn! I haven't seen anything to suggest that lionfish preferentially spawn at lower depths, but because the egg balls dissolve about 24 after spawn, the tiny individual eggs drift in the water for a little while before hatching. All together, lionfish eggs may be tough to spot!
