A nanoscale motor in the ear

Utah and Texas researchers have learned how quiet sounds are magnified by bundles of tiny, hair-like tubes atop "hair cells" in the ear: when the tubes dance back and forth, they act as "flexoelectric motors" that amplify sound mechanically.

Researchers show how PCBs may alter in utero, neonatal brain development

In three new studies - including one appearing online in the Public Library of Science - Biology (PLoS - Biology) - UC Davis researchers provide compelling evidence of how low levels of polychlorinated biphenyls (PCBs) alter the way brain cells develop.

Experimental drug fampridine improves mobility for some MS patients

In MS, the body's immune system attacks myelin, a fatty tissue that wraps and insultates nerve fibers, disrupting the transmission of signals in the central nervous system.

Experimental antiarrhythmic drug dronedarone reduces death rate in patients with atrial fibrillation

Results from the ATHENA trial, reported in the 12th February issue of the New England Journal of Medicine , suggest that the (as yet unlicensed) antiarrhythmic drug dronedarone can reduce the incidence of cardiovascular-related hospitalisation or death in patients with atrial fibrillation.

Cellular changes in the sleeping brain promote the formation of memories

If you ever argued with your mother when she told you to get some sleep after studying for an exam instead of pulling an all-nighter, you owe her an apology, because it turns out she's right.

Widespread antiviral drug use can accelerate the evolution of drug resistance in viruses

Influenza's ability to resist the effects of cheap and popular antiviral agents in Asia and Russia should serve as a cautionary tale about U.S. plans to use the antiviral Tamiflu in the event of widespread avian flu infection in humans, scientists say.

New understanding of ion channels in the body

A discovery by Canada-U.S. biophysicists will improve the understanding of ion channels, akin to little 'nano-machines' or 'nano-valves' in our body, which when they malfunction can cause genetic illnesses that attack muscles, the central nervous system and the heart.
