Breakthrough study shows how plants sense the world

Plants lack eyes and ears, but they can still see, hear, smell and respond to environmental cues and dangers—especially to virulent pathogens. They do this with the aid of hundreds of membrane proteins that can sense microbes ...

Video of virus-sized particle trying to enter cell

Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed ...

DNA nanorobot triggers targeted therapeutic responses

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a robotic device made from DNA that could potentially seek out specific cell targets within a complex mixture of ...

How protein receptors on cells switch on and off

Cornell researchers have provided new insight into the molecular mechanism underlying an essential cellular system. They have discovered how receptors on cell surfaces turn off signals from the cell's environment, a function ...

EphA4 -- the molecular transformer

(PhysOrg.com) -- EphA4 is a protein which is attached to the surfaces of many types of human cells and plays a role in a wide range of biological processes. EphA4 functions by binding to ephrin ligands, cell surface proteins ...
