Three-dimensional images of human small ribosomal subunits offer the most detailed explanation for how the cell's protein-making machines are assembled.

Animals as small and soft as tardigrades seldom have legs and almost never bother walking. But a new study finds that water bears propel themselves through sediment and soil on eight stubby legs, in a manner resembling that of insects 500,000 times their size.

A novel method for studying how one crucial membrane protein functions may pave the way for a new kind of broad-spectrum antibiotic.

Drug-resistant strains of tuberculosis bacteria affect half a million people a year. A compound first discovered in the 1980s may be able to help.

Scientists are digging through drug libraries of 430,000 compounds, in pursuit of an antiviral drug that can stop the novel coronavirus in its tracks.

In a painstaking experiment, scientists suspended a single protein filament between two microscopic beads. Their results have shed light on an elusive process in which cells receive and respond to mechanical cues.

Rice will receive the 2020 Nobel Prize in Physiology or Medicine for research that led to a cure for hepatitis C, a viral disease affecting 170 million people worldwide. His lab worked on the virus for three decades and became the first to produce a version of it that could be grown and studied i...

New research suggests that breast and lung tumors metastasize by hijacking a neural signaling pathway, potentially opening the door to better diagnostics and treatments.

A new molecular structure explains how cells hold an alarm-triggering protein captive during cell division, preventing cells from targeting their own DNA.

The high-resolution 3D image can speed COVID-19 drug discovery.
