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...

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

Researchers studying two forms of skin cancer identified a long-overlooked factor determining why some tumors are more likely to metastasize than others: the physical properties of the tissue in which the cancer originates. The findings might set the stage for new ways to monitor and treat the di...

Scientists hope to deploy antibodies in the quest to end COVID-19. A recent study moves them closer to accomplishing a key step: finding out if the virus may acquire resistance to antibody-based drugs or vaccines, and how to potent...


Scientists have engineered four viruses resembling SARS-CoV-2 to enable faster and safer research on vaccines and treatments.

In findings that might lead to better smoking-cessation tools, scientists have shown that manipulating a specific brain receptor can alter a mouse’s nicotine sensitivity.

The discovery of a rare mutation in BRCA2, commonly known as the breast cancer gene, has shed new light on how cells safeguard their genetic material.
 

The new imaging technique enables researchers to construct a comprehensive image of blockages and other vascular injuries.

Over 130 scientists in 18 labs are conducting research to advance the development of new, urgently needed approaches for the prevention and treatment of COVID-19.
