UK researcher identifies brain region responsible for spatial hearing
A major science prize was today awarded to a researcher who is looking for the region of the brain that helps us to hear someone in a noisy place, such as a party or bar, and is responsible for "training" the brain to hear better in these situations.

Beta-actin mutations linked to deafness and dystonia
Findings of a recent genetic study on developmental brain disorders may be the "tip of an iceberg" revealing factors involved with a number of congenital diseases, according to UC Irvine researchers. The study is the first to find that mutations in the structural proteins in brain cells - beta-actin - are linked to disorders such as deafness and dystonia, a debilitating neural disease, and further suggests that genetic variants of these proteins may play a wider role with inherited human diseases. Study results appeared in the June issue of the American Journal of Human Genetics.

Aldosterone linked to good hearing as we age
Researchers have linked a hormone known to adjust levels of key brain chemicals to the quality of our hearing as we age. The more of the hormone that older people have in their bloodstream, the better their hearing is, and the less of the hormone, the worse their hearing is.

Salicylate causes tympanic membranes to rupture more easily
It's well known that high doses of aspirin can cause ulcers and temporary deafness, but the biochemical mechanism responsible for these phenomena has never been deciphered. New research from Rice University offers clues, showing for the first time how salicylate -- an active metabolite of aspirin -- weakens lipid membranes. Researchers believe these mechanical changes disrupt the lining of the stomach, which functions to protect underlying tissue from the acidic contents of the gut. By a similar mechanism, the changes may result in aspirin-related deafness by interfering with the proper function of prestin, a transmembrane protein that's critical for mammalian hearing.

Amount of hearing in an ear prior to surgery is unrelated to a patient's ability to interpret speech using an implant
Hearing-impaired individuals with severe to profound hearing loss and poor speech understanding who possess some residual hearing in one ear may experience significant communication benefit from a cochlear implant even if it is placed in the worse-hearing ear, a Johns Hopkins study suggests.

Spatial Hearing Aid Can Provide Direction of Sound
Over three million Australians suffer from hearing loss but fewer than 20 per cent of them use hearing aids. Part of the problem is that technology just isn't good enough for them. Researchers from Sydney are changing that.

Stem Cells to Help Hearing Impaired
Researchers at Indiana University School of Medicine are several steps closer to the day when a profoundly deaf patient's own bone marrow cells could be used to let him or her hear the world.
