New drug restores hearing after noise-induced hearing loss in rats (July 2, 2010) -- Researchers from New Zealand have discovered that a potent new drug restores hearing after noise-induced hearing loss in rats. The landmark discovery found that injection of an agent called 'ADAC' activates adenosine receptors in cochlear tissues, resulting in recovery of hearing function. The finding paves the way for effective non-surgical therapies to restore hearing loss after noise-induced injury. ... > full story
Discovery of a hepatitis C-related virus in bats may reduce outbreaks in humans (July 2, 2010) -- Viral hepatitis affects more than 500 million people worldwide and while vaccines are available for hepatitis A and B, this is not the case for hepatitis C, which affects as much as two percent of the population in the US. Now, scientists are reporting discovery of a virus related to hepatitis C in Asian bats, which may provide insights into the origins of the hepatitis C virus. ... > full story
Warmer is better: Invasive cane toads set to thrive under global warming (July 2, 2010) -- As global warming threatens many animal species with extinction, the cane toad is set to flourish with increasing temperature. This is a major cause for concern as the cane toad, once introduced to Australia as agricultural pest-control of the cane beetle, is an already highly invasive species and considered a pest in Australia. ... > full story
High fructose diet may contribute to high blood pressure, study finds (July 2, 2010) -- People who eat a diet high in fructose, in the form of added sugar, are at increased risk of developing high blood pressure, or hypertension, according to a new study. The results suggest that cutting back on foods and beverages containing a lot of fructose (sugar) might decrease one's risk of developing hypertension. ... > full story
Stroke complications may subtract additional two years of healthy life (July 2, 2010) -- Stroke complications may deprive patients of about two years of healthy life, in addition to three years of healthy life lost due to the stroke, according to a South Korean study. A combined measure of potential life years and function lost can impact public health decisions, researchers said. However, it's unclear if the findings can be applied to other populations. ... > full story
Scrubbing CO<sub>2</sub> from atmosphere could be a long-term commitment (July 2, 2010) -- With carbon dioxide in the atmosphere approaching alarming levels, even halting emissions altogether may not be enough to avert catastrophic climate change. Could scrubbing carbon dioxide from the air be a viable solution? A new study suggests that while removing excess carbon dioxide would cool the planet, keeping carbon dioxide at low levels would require a long-term commitment spanning decades or even centuries. ... > full story
Planned home births associated with tripling of neonatal mortality rate vs. planned hospital births (July 2, 2010) -- In a new study, researchers report that less medical intervention, characteristic of planned home births, is associated with a tripling of the neonatal mortality rate compared to planned hospital deliveries. Planned home births were characterized by a greater proportion of deaths attributed to respiratory distress and failed resuscitation. ... > full story
