Advances in sequencing technologies have finally allowed researchers to zero in on the genetic diversity underlying the incredible mating system of shelf fungi.

Officials have ruled out known hepatitis viruses as the cause of a rash of illnesses in Europe and the US.

Several lines of evidence suggest that targeting the body’s defense pathways might help treat a subset of people with the psychiatric disorder. But many open questions remain.

The Swiss Federal Institute of Technology Lausanne evolutionary neurobiologist is using Drosophila to investigate how organisms adapt to novel environments.

Do members of Homo floresiensis still inhabit the Indonesian island where their fossils helped identify a new human species fewer than 20 years ago?

Some experts argue that better trials are needed before putting interventions into practice.

Southern Australia has recorded its first-ever cases of the disease in an outbreak that has so far killed three people.

In vitro and mouse experiments show how cancer cells forced through tiny pores—mimicking the physical experience of metastasis—resisted programmed cell death and avoided detection by the immune cells that would normally kill them.

Observational evidence for the connection is solidifying, and some clues are emerging about the mechanisms that may explain it.

New research in mice reveals why natural killer cells, normally effective at hunting cancer, are sometimes stopped in their tracks.  

Pregnant mosquito females deploy the microbe Elizabethkingia to speed larval growth; the larvae, in turn, help the bacteria outcompete other strains.

A study in mice finds that for certain genes, one parent’s allele can dominate expression and shape behavior—and which parent’s allele does so varies throughout the body.
