'Holy Grail' of hearing: True identity of pivotal hearing structure is revealed
Our ability to hear is made possible by way of a Rube Goldberg-style process in which sound vibrations entering the ear shake and jostle a successive chain of structures until, lo and behold, they are converted into electrical signals that can be interpreted by the brain. Exactly how the electrical signal is generated has been the subject of ongoing research interest.

New study finds infant hearing test results may predict sudden infant death syndrome
SEATTLE: July 26, 2007 One of the greatest medical mysteries of our time has taken a leap forward in medical understanding with new study results announced by Dr. Daniel D. Rubens of Childrens Hospital and Regional Medical Center in Seattle. Rubens study published in July, 2007 in Early Human Development found all babies in a Rhode Island study group who died of Sudden Infant Death Syndrome (SIDS) universally shared the same distinctive difference in their newborn hearing test results for the right inner ear, when compared to infants who did not have SIDS. This is the first time doctors might be able to identify newborns at risk for SIDS by a simple, affordable and routine hearing test administered shortly after birth. In the study, medical records and hearing tests of 31 babies who died from SIDS in Rhode Island were examined and compared to healthy babies. Rhode Island has a particularly robust database of newborn hearing test data.

Ability to listen to 2 things at once is largely inherited, says twin study
Your ability to listen to a phone message in one ear while a friend is talking into your other ear?and comprehend what both are saying?is an important communication skill that?s heavily influenced by your genes, say researchers of the National Institute on Deafness and Other Communication Disorders (NIDCD), one of the National Institutes of Health. The finding, published in the August 2007 issue of Human Genetics, may help researchers better understand a broad and complex group of disorders?called auditory processing disorders (APDs)?in which individuals with otherwise normal hearing ability have trouble making sense of the sounds around them.

Some children are born with 'temporary deafness' and do not require cochlear implant
Clinical research conducted in the Department of Communication Disorders at the University of Haifa revealed that some children who are born deaf recover from their deafness and do not require surgical intervention. To date, most babies who are born deaf are referred for a cochlear implant. Many parents will say to me: 'My child hears; if I call him, he responds'. Nobody listens to them because diagnostic medical equipment did not register any hearing. It seems that these parents are smarter than our equipment, said Prof. Joseph Attias, a neurophysiologist and audiologist in the Department of Communication Disorders at the University of Haifa, who made the discovery.

Study shows isolation of stem cells may lead to a treatment for hearing loss
CLEVELAND, OH -- Have you ever walked by someone listening to their i-Pod loud enough for you recognize the song? Studies have shown noise-induced hearing loss is going to become the next big epidemic affecting our younger generation though the effects wont show until it is too late to treat. In addition to loud noise, certain cancer drugs or genetic factors can cause hearing loss in humans due to loss or faulty development of the sensory microphones (hair cells) inside the ear the cochlea. Lost hair cells are not replaced and people exposed to these conditions face permanent hearing loss. Identification of the stem cells from the adult cochlea would be a major step forward to develop new therapeutic approaches to hearing loss.

Role of Folic Acid in Treatment of Laryngeal Leucoplakia
Folic acid supplements may prevent cancer progression and promote regression of disease, according to a new study. Published in the July 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the small study found that 31 of 43 patients with the precancerous laryngeal lesion called leucoplakia demonstrated 50 percent or greater reduction in the lesion size after six months of taking folate supplements. In 12 of 31 responders, there was no evidence of the original lesion. Folate levels in the patients' blood also increased significantly from baseline while homocysteine levels decreased significantly. This study provides data to support the hypothesis that folate insufficiency is a risk factor for cancer progression.

Scientists discover reason behind ear canal in Chinese frog: Ultrasonic communication
Amolops tormotus, also referred to as the concave-eared torrent frog, is the first non-mammalian species found to be capable of producing and detecting ultrasounds for communication, much like dolphins, bats, and some rodents. It does so, the researchers report, to make itself heard above the din of low-frequency sounds produced in its surroundings so that it can communicate territorial information to other males of its species. In addition to helping researchers puzzle out how the ear evolved, the research may one day enable scientists to develop new strategies or technologies that help people to hear in environments in which there is a lot of background noise.

New vaccine against ear infection
Czech scientists have developed a vaccine to help prevent ear infections in young children. Next to the common cold, ear infections are the most commonly diagnosed childhood illness. More than three out of four children in the US have at least one ear infection by the time they reach three years of age. The infection known as acute otitis media could be very painful and - very rarely - cause long term damage. Roman Prymula, from the University of Defence at Hradec Kralove, Czech Republic, administered almost 5,000 infants with either the ear vaccine or a hepatitis A vaccine at various ages between three and 15 months.

But research, using computers to do extended therapy, now indicates that these patients can continue to improve even many years after their stroke or brain trauma. Lingraphicare America, developers of the Lingraphica speech generating device for aphasia, has published results of studies which show significant improvements after use of the device over a period of approximately 20 weeks.

It's well established that neonates have a preference for speech above other sounds, but where does this come from? Is it something that's built in and there's something about the speech signal that they're tuned to listen to without the benefit of experience, or does it come from their prenatal experience in the womb? I think we've shown that there's an experience-independent component to newborns' preference for speech, says Dr. Vouloumanos, an Assistant Professor in McGill's Department of Psychology in Montreal, Canada.
