Electric charge disorder: A key to biological order?
Theoretical physicist Ali Naji from the IPM in Tehran and the University of Cambridge, UK, and his colleagues have shown how small random patches of disordered, frozen electric charges can make a difference when they are ...

Plastic 'ninjas' take on deadly bacteria (w/ Video)
For decades, bacteria like the stubborn methicillin-resistant Staphylococcus aureus (MRSA) have concerned gym goers, hospital patients and staff, and parents of school children. MRSA is particularly worrisome because it is ...
Chemist creates trapping technique for nanoparticles
(PhysOrg.com) -- A chemist at the University of Wisconsin-Milwaukee (UWM) has developed a kind of invisible fence for trapping and controlling particles as small as a single virus or large protein.
Image: Ghostly spokes in the rings
Scientists first saw these somewhat wedge-shaped, transient clouds of tiny particles known as "spokes" in images from NASA's Voyager spacecraft.
Spider webs more effective at ensnaring charged insects
Flapping insects build up an electrical charge that may make them more easily snared by spider webs, according to a new study by University of California, Berkeley, biologists.
