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.

In two related studies, researchers describe huge chromosomal rearrangements and about 500 novel gene clusters in the octopus, squid, and cuttlefish genomes, which they say could help explain how they evolved their extraordinary brains.
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.
Studies The Scientist covered this year illustrate the expanding importance of genetic and genomic research in all aspects of life science, from ecology to medicine.
A comparison of interferon-related genes across 20 primate genomes reveals differences in the speed at which they evolve and new targets for antiviral discovery efforts.
Rather than introducing small chunks of DNA as other viruses do, some giant viruses can contribute more than 1 million base pairs to a host’s genome, broadening the ways in which viruses may shape eukaryote evolution.
