Bats’ remarkable ability to withstand decades of strenuous flight while keeping infections, inflammation, and cancer in check may offer new clues to healthier human aging Bats are unusually long-lived for animals of their size. Small mammals generally burn energy quickly and die relatively young, yet some bats survive for several decades. Brandt’s myotis, Myotis brandtii, [...]

For several decades, paleontologists have described Miracinonyx trumani -- an extinct species of cheetah-like felid that roamed the North American prairies and steppe terrains more than 13,000 years ago -- as North America’s answer to the African cheetah (Acinonyx jubatus).

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.

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 [...]
