Ancient Viral DNA Helps Mouse Brains Fight Infection
Mammals that give birth to live young may have evolved to make use of the remnants of viruses in their genomes to ward off pathogens, a study suggests.

DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.
A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
Hydra vulgaris constantly replenish the cells in their heads and grow new ones to reproduce asexually. But gene expression analyses reveal that regenerating a head after an injury is a very different process.
A massive screen of bacterial and archaeal genomes revealed five previously unknown instances where an organism uses an alternate code to translate genetic blueprints into proteins.
Researchers found the relatively high proportion of DNA from a hominin cousin—nearly 5 percent—when they scanned more than 1,000 genomes from 118 distinct ethnic groups.
Bettas were likely the first fish welcomed into human homes. Now, scientists are welcoming them into the lab to learn how genes dictate their appearance and behavior.
A massive, well-preserved skull discovered in China in the 1930s belongs to a new species called Homo longi, researchers report, but experts remain skeptical about the evidence.
A mutant protein called Siglec-XII may promote carcinoma progression in humans, but inactivation of its gene seems to avoid the problem, according to a study.
