How a shape-shifting receptor influences cell growth

Receptors found on cell surfaces bind to hormones, proteins, and other molecules, helping cells respond to their environment. MIT chemists have now discovered how one of these receptors changes its shape when it binds to ...

Bull ant evolves new way to target pain

Australian bull ants have evolved a venom molecule perfectly tuned to target one of their predators—the echidna—that also could have implications for people with long-term pain, University of Queensland researchers say.

New technique tracks individual protein movement on live cells

The piece of gold that Richard Taylor was thrilled to track down weighed less than a single bacterium. Taylor, a postdoctoral fellow at the Max Planck Institute, was working to follow individual nanogold-labeled molecules ...

Nanoscopic protein motion on a live cell membrane

Cellular functions are dictated by the intricate motion of proteins in membranes that span across a scale of nanometers to micrometers, within a time-frame of microseconds to minutes. However, this rich parameter of space ...
