Understanding how domestic pigs can be infected with the deadly virus could be key to protecting them from it.

A newly identified group of viruses may help suppress eukaryotes’ immune response and promote tolerance of endosymbiotic bacteria.

Researchers suggest the viruses can help endosymbiotic bacteria get along with their hosts.

A devastating outbreak of the virus across East Asia has made the long-neglected pathogen a top research priority, but many challenges lie ahead.

The virus, which has sickened at least 59 people, does not appear to transmit easily between humans.

This year’s most beautiful illustrations covered topics including the molecular underpinnings of Parkinson’s disease and strategies for tracking marine organisms around the world’s oceans.

The public health emergency has spurred a mass vaccination campaign.

In rare instances, the live virus in oral polio vaccines can mutate and become infectious, causing new outbreaks.

Aedes aegypti infected with Wolbachia—which inhibit transmission of the dengue virus from insect to human—were deployed in Indonesia, Vietnam, Brazil, and Australia.
