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 Zurich. Prof. Krishnan ...

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 ...

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 ...

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.

Acoustic levitation could be used on Mars

(PhysOrg.com) -- The presence of fine dust on the Moon and Mars may present problems for explorers, such as coating solar panels, penetrating seals and interfering with machinery. Human explorers would also be endangered ...
