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 ...

DNA nanorobots find and tag cellular targets

Researchers at Columbia University Medical Center, working with their collaborators at the Hospital for Special Surgery, have created a fleet of molecular "robots" that can home in on specific human cells and mark them for ...

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 ...

Scorpion venom with nanoparticles slows spread of brain cancer

By combining nanoparticles with a scorpion venom compound already being investigated for treating brain cancer, University of Washington researchers found they could cut the spread of cancerous cells by 98 percent, compared ...

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 ...
