How cells use mechanical tension sensors to interact with their environment

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.

Rockefeller's Charles M. Rice honored with Nobel Prize for research that contributed to a cure for hepatitis C

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...

How dividing cells avoid setting off false virus alarms

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

Transparent fish reveal the subtle, cellular dance in which sensory organs take shape

How do primitive cells “know” where to go during development? Scientists studying the fish equivalent of inner-ear hair cells have shown that biochemical and mechanical cues work together to orchestrate a highly complex arrangement.
