Gene-therapy trial to restore hearing in deaf mice

Researchers have found long-sought genes in the sensory hair cells of the inner ear that, when mutated, prevent sound waves from being converted to electric signals - a fundamental first step in hearing. The team, co-led by Jeffrey Holt, PhD, in the department of otolaryngology at Children-s Hospital Boston, and Andrew Griffith, MD, PhD, of the NIH-s National Institute on Deafness and other Communication Disorders (NIDCD), then restored these electrical signals in the sensory cells of deaf mice by introducing normal genes.

Cisplatin anti-cancer drug binds pervasively to RNA

An anti-cancer drug used extensively in chemotherapy binds pervasively to RNA -- up to 20-fold more than it does to DNA, a surprise finding that suggests new targeting approaches might be useful, according to University of Oregon researchers.

ChanRx to evaluate AFIB drug, vanoxerine with closed Series A funding

ChanRx is developing a superior drug for treatment of atrial fibrillation (AFIB), and has closed its Series A funding with investments from Sante Ventures and company founder, Dr. Arthur "Buzz" Brown. The company, a spin out of Cleveland-based ChanTest, will use the funding to further evaluate the safety and efficacy of its proprietary AFIB drug, vanoxerine.

New material emits long-lasting, near-infrared glow after sunlight exposure

Materials that emit visible light after being exposed to sunlight are commonplace and can be found in everything from emergency signage to glow-in-the-dark stickers. But until now, scientists have had little success creating materials that emit light in the near-infrared range, a portion of the spectrum that only can be seen with the aid of night vision devices.

Researchers describe how brain handles spatial resolution

Everybody knows how to zoom in and out on an online map, to get the level of resolution you need to get you where you want to go. Now researchers have discovered a key mechanism that can act like a zoom button in the brain, by controlling the resolution of the brain's internal maps.

State roundup: Calif. cuts make public health outlook bleak

One thing Gov. Mitch Daniels believes with absolute conviction is that consumers need to pay more of the cost of their health care. ... No one can say Daniels isn't practicing what he preaches. Indiana has been using a version of consumer-driven health care for state employees since 2006. Starting next year, 90 percent of Indiana state workers will be covered by a consumer-driven plan with low premiums and high out-of-pocket expenses for actual care.

Research shows how the bite of a small Texas snake causes extreme pain

Examining venom from a variety of poisonous snakes, a group of researchers at the University of California, San Francisco has discovered why the bite of one small black, yellow and red serpent called the Texas coral snake can be so painful.

New computer chip models how neurons communicate with each other at synapses

For decades, scientists have dreamed of building computer systems that could replicate the human brain's talent for learning new tasks. MIT researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain's neurons adapt in response to new information. This phenomenon, known as plasticity, is believed to underlie many brain functions, including learning and memory.

Luminescent upconversion nanocrystals can detect cancer cells

Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These materials could be used as biomarkers for luminescent labeling of cancerous cells. Opaque tissues can be turned into glassy, transparent substances by using these biomarkers which rely on near-infrared excitation.

New insight into how ammonia is formed

For the past 100 years, the Haber-Bosch process has been used to convert atmospheric nitrogen into ammonia, which is essential in the manufacture of fertilizer. Despite the longstanding reliability of the process, scientists have had little understanding of how it actually works. But now a team of chemists, led by Patrick Holland of the University of Rochester, has new insight into how the ammonia is formed.

Researchers identify how to design drugs to target specific brain areas

The future of drug design lies in developing therapies that can target specific cellular processes without causing adverse reactions in other areas of the nervous system. Scientists at the Universities of Bristol and Li-ge in Belgium have discovered how to design drugs to target specific areas of the brain.

Legislation news: Obama promises to veto anti-abortion bill

The House is expected to pass an abortion-related bill today, but like other similar legislation, it is not likely to make progress in the Democrat-controlled Senate. Meanwhile, a number of other health-related measures and subjects are moving on both sides of the Capitol, including a rural health proposal and another related to a health tax credit aimed at easing the contractor tax compliance burden. Lastly, two Senate Democrats expressed concerns about the Prevention Trust Fund's advisory panel.
