Neanderthals vanished roughly 42,000 years ago, but a piece of their biology appears to be quietly at work in some people today, according to a new study led by scientists from the Max Planck Institute for Evolutionary Anthropology.
A lot of the AI work in biology has been focused on designing proteins. That's partly because proteins do most of the business of life, catalyzing the interesting chemistry and structuring cells. So, figuring out how to make a new protein can mean directly tinkering with biochemistry, providing new and potentially useful functions.
Since the genetic code provides a layer of abstraction between DNA and proteins, it wasn't obvious what a model trained on DNA could do. Yet people went ahead and made a large genome model, and it turned out to be able to output DNA sequences that could encode functional proteins in bacteria and mimic the gene structures found in complex cells. Now, those same models have been used to output the genomes of viruses that infect bacteria.
This isn't science fiction—all the viruses the models created are closely related to an existing virus. But they do have some distinct features that would be challenging to evolve. And the researchers who did the work, based at Stanford University, suggest we may want to start thinking now about preparing for the potential that someone could develop a related AI that can design a virus that targets vertebrates.
More than 150 years after Charles Darwin first wondered whether certain sticky-leaved Saxifraga plants might be secretly carnivorous, Kunming Institute of Botany researcher Tao Deng and colleagues say they have finally confirmed it.
New research led by the University of California, Berkeley reveals that beyond Neanderthals and Denisovans, humans interbred with two mysterious ‘ghost’ lineages: one in Africa more than 50,000 years ago, another in Eurasia over 1.7 million years ago.
A large British study spanning more than 70 years has found that people who experience chronic money struggles over their working lives show measurable declines in memory and processing speed by their 50s, along with signs of accelerated brain shrinkage decades later.

Researchers have identified and formally described a new species of the African monkey genus Colobus living in the remote interior of the Democratic Republic of Congo, marking only the fifth new monkey species found on the continent in the past 75 years.
Chaque été, les dermatologues rappellent l'importance de protéger sa peau du soleil. Mais une vaste étude génétique menée par des chercheurs australiens montre que le risque de mélanome ne dépend pas seulement des UV.
A new long-read DNA test improves rare disease diagnosis, replaces multiple existing tests, and could become the preferred global standard for genetic diagnostics. A new DNA test is providing a far more detailed view of the genome than current standard diagnostic methods, helping doctors identify rare genetic disorders more often. The test can replace up [...]
Le soleil ne se contente plus d'éclairer les journées : il peut aussi alléger la facture d'électricité. Avec l'arrivée de la gamme SolarVault 3 en France, Jackery rend le stockage solaire domestique plus accessible grâce à des batteries résidentielles proposées à partir de 839 euros. Une...
Des chercheurs viennent de franchir une étape que la biologie considérait encore récemment comme inaccessible : rajeunir de vraies cellules humaines. Non pas les remplacer mais pour les rajeunir. Cette avancée, qui a eu lieu il y a quelques mois, mérite qu'on s'y attarde sérieusement, tant ses...
Two elusive groups of millipedes, Siphoniulida and Siphonocryptida, were the last missing pieces in the evolutionary history of Earth’s oldest land animals, according to a team of entomologists led by Virginia Tech.
The extinct Eurasian cave lion (Panthera spelaea) and today’s African and Asian lions (Panthera leo) belong to separate evolutionary lineages that diverged roughly 1.7 million years ago -- far earlier than previously thought, according to an analysis of 12 cave lion genomes spanning more than 100,000 years.
In new research, scientists sequenced and analyzed chromosome-level genomes of the Linnaeus’s two-toed sloth (Choloepus didactylus) and the southern anteater (Tamandua tetradactyla).
