Harvey Alter, Michael Houghton and Charles Rice were awarded the 2020 Nobel Prize in Physiology or Medicine for their discovery of the cause of a major liver disease.

New research finds that the subjective experience of time is linked to learning, thwarted expectations and neural fatigue.

A novel form of immunological memory that was mostly ignored for a century extends the benefits of vaccines. It could be of help in ending the COVID-19 pandemic.

Carpenter ants need endosymbiotic bacteria to guide the early development of their embryos. New work has reconstructed how this deep partnership evolved.

Recent major surveys show that reductions in genomic complexity — including the loss of key genes — have successfully shaped the evolution of life throughout history.

Studies suggest that self-disseminating vaccines could prevent the “spillover” of animal viruses into humans as pandemic diseases.

Emperor penguins display rigorously geometric spacing and mathematical efficiency when they huddle together for warmth, which may reveal secrets to their overall health.

A new model shows that the denizens of a vast, ancient biome beneath the seafloor use barely enough energy to stay alive — and broadens understanding of what life can look like.

Research hints that the energy-generating organelles of cells may play a surprisingly pivotal role in mediating anxiety and depression.
