New device for identifying aggressive breast cancers

A new disposable device based on advances in microfluidics may help identify advanced breast cancer patients who are candidates for therapy with the drug trastuzumab (Herceptin). The device is described in the American Institute ...

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 ...

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 ...
