Researchers explore the idea that molecular patterns in individual cells could underlie the development of a left and a right in animals.

Researchers discover that bacteria break down medicinal compounds for their nitrogen, solving a mystery that has vexed aquatic veterinarians for years.

The pandemic has yielded many lessons. One is that adequate and well-distributed diagnostics are key to battling disease outbreaks.

An epigenome-wide association study found more than a dozen methylation changes in placental DNA that correlated with expectant mothers’ self-reports of depression and stress during their pregnancy.

In work that has not yet been peer-reviewed, researchers present evidence that microbes can and do live inside the venom glands of several dangerous species. It remains unclear whether they’re to blame for infections linked to bites.

Data from mouse models for mild coronavirus infections and human tissue samples offer further evidence that it doesn’t take a severe infection—or even infection of brain cells at all—to cause long-term neurological symptoms.

This strain of SARS-CoV-2 is causing new outbreaks in Europe and Asia and may spread slightly faster than the better-known BA.1 Omicron subvariant, although it’s too early to say for sure.

By breaking down urea, the animals’ gut bacteria recycle nitrogen, which can be then used to build new molecules during prolonged fasting.

A new method helps researchers uncover the rules of ribosome recruitment in yeast.

Whole genome sequences reveal multiple domestications of this agriculturally important tree and may hold the secrets to producing the sweet fruit year round.

The field of ancient DNA, which combines archaeology and anthropology with cutting-edge genetics, is requiring scientists to have frank conversations about when research is justified and who it benefits.

A new chemical treatment allowed African clawed frogs, which normally don’t regenerate limbs, to regrow functional hind legs following amputation.
