Viable offspring derived from single unfertilized mammalian oocytes

- fallingfrog 3y agoI hope!
- JeanSebTr 3y agothat's the kind of news I expect to be in mice and not in humans ;)
- bpodgursky 3y agoThis is a case where there's not a super compelling reason to believe it would fail in other mammals.
- dools 3y agoYeah my favourite "in mice" story is cryogenics: https://www.youtube.com/watch?v=2tdiKTSdE9Y https://www.youtube.com/watch?v=2tdiKTSdE9Y
- RobotToaster 3y agoNext, dinosaurs.
- Idiot_in_Vain 3y agoDinos are a few orders of magnitude harder. No DNA or RNA fragment can even remotely survive over 65M years. To make something similar to a dino researchers will have to produce a working mix of bird and reptilian DNA - which is enormously complicated.
- amanaplanacanal 3y agoPlenty of avian dinosaurs around. Just not the ones you're thinking about.
- rf15 3y agoIsn't this kind of research illegal? Because the results usually are. (I say as someone who used to own marbled crayfish[1]) [1] https://en.m.wikipedia.org/wiki/Marbled_crayfish https://en.m.wikipedia.org/wiki/Marbled_crayfish
- jacquesm 3y agoInteresting, they forbid to 'breed' it but that's apparently not really how it works for these particular animals. A single individual will be happy to reproduce without any breeding taking place and there isn't much that you could do to stop it short of killing the creature.
- RicoElectrico 3y agoBut is it because of the origin, or rather the invasive species status?
- Bang2Bay 3y agof*k... Oh. we dont have to any more. :)
- 082349872349872 3y agoIn Brave New World, they don't have to fuck, yet find plenty of opportunity to do so anyway. (and we are told this is somehow a dystopia?) Lagniappe: "cloning can be worthwhile" https://www.youtube.com/watch?v=BMkjoQ6S7oQ https://www.youtube.com/watch?v=BMkjoQ6S7oQ
- bitwize 3y agoReferences to crawfish and lagniappe in the same HN thread? My wife would be over the moon!
- midoridensha 3y agoYeah, Brave New World is a really interesting work of dystopian fiction IMO, because many people disagree that it's "dystopian", unlike 1984 which it's often compared with. No one thinks living in the world of 1984 sounds appealing, but BNW sounds like a pretty nice place actually, but the anti-BNW crowd tries to tell us it's horrible because it's "unnatural" or "against family values" or something like that. Meanwhile, in the real world today, many families are completely broken (and many were in Huxley's time too, except they didn't get divorced, they just suffered), the marriage rate has gone down, the birthrate is unsustainably low, and young people frequently aren't even having sex any more, leading many to be isolated and depressed. Personally, I fail to see how adopting a BNW-style society could possibly be any worse than what we have now; indeed, it seems like a huge improvement in most ways.

- Spivak 3y agoWell the "we have the ability to alter humans so we're all strong, healthy, and intelligent but we not only choose not to do that but choose to stunt development of some humans to produce a docile compliant workforce for menial labor" is pretty darn dystopian no matter how you swing it. And if you say "oh that wouldn't be so bad" you can even put your money where you mouth is -- would you be fine with being deprived of oxygen long enough to cause minor brain damage but otherwise not harm you? Done right you wouldn't feel a thing too. You can volunteer to be permanently dumber. Huxley describes very eloquently how one end by two means are not the same. Human variation that arises naturally but at all times people are trying their best is a fact of life. But humans taking the reins and making that same variation by choice for their own desires is dystopian.

- photochemsyn 3y agoI remain hopeful... > "The 28,000-year-old remains of a woolly mammoth, named 'Yuka', were found in Siberian permafrost. Here we recovered the less-damaged nucleus-like structures from the remains and visualised their dynamics in living mouse oocytes after nuclear transfer." https://pubmed.ncbi.nlm.nih.gov/30858410/ https://pubmed.ncbi.nlm.nih.gov/30858410/

- amateurCoder5 3y agoTLDR: transfer of 155 parthenogenetic embryos generated two live offspring. Both had body weight similar to that of controls at birth and survived to adulthood. Seems like there are still a lot of unknowns in this process, so caution is warranted.
