Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.

Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.

Sequences for the model organism and two of its kin reveal how these plants got their oversized genomes.

The University of St. Andrews behavioral ecologist studies the social structures and behaviors of whales and dolphins, recording and analyzing their acoustic communications.

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.

As much as rainforests or deep-sea vents, the human gut holds rich stores of microbial chemicals that should be mined for their pharmacological potential.

The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.

Metabolic disrupters, phages, and other approaches are going to be needed to treat the broadest possible range of patients infected by bacterial pathogens resistant to multiple drugs.
