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. 

Seventeen studies coauthored by Gregg Semenza have been retracted, corrected, or raised for concern, and 15 more are currently under investigation.

The journal’s executive director speaks with The Scientist about what it hopes to accomplish with its unusual new publishing model.

The findings answer the longstanding question of where these cells hold the mRNA needed to cope with the transcriptional halt preceding meiosis.

A new study points to repercussions of the Medieval pandemic for the health of modern humans.

The black fur allele has fitness costs but also confers higher immunity against canine distemper virus, making mix-and-match mating key to population survival.

A method appears to be the first to noninvasively reconstruct language from brain activity.

People with more carboxylic acids in their body odor are more attractive to mosquitoes, a study finds.

Viral remnants make up 8 percent of the human genome, and a new study finds that these sequences are still active in healthy people.

Mice that received the stem cell–derived treatment were less frail compared with controls, a study reports.

A study adds to evidence linking gut bacteria to liver conditions in people who don’t drink excessive amounts of alcohol. 

Epigenetic events, such as methylation, during early brain development in mice occur in genomic regions associated with BMI in humans, according to a new study.
