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 ...
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.

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.
Researchers measure the electrical charge of nano particles
Nano particles are a millionth of a millimeter in size, making them invisible to the human eye. Unless, that is, they are under the microscope of Prof. Madhavi Krishnan, a biophysicist at the University of ...
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 ...
Ghostly 'Spokes' Puff Out From Saturn's Ring's (w/ Video)
(PhysOrg.com) -- Massive, bright clouds of tiny ice particles hover above the darkened rings of Saturn in an image captured by the Cassini spacecraft on Sept. 22, 2009, around the time of Saturn's equinox. ...
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.
