Treatment For Hearing Loss? Scientists Grow Hair Cells Involved in Hearing (August 30, 2008) -- Scientists have successfully produced functional auditory hair cells in the cochlea of the mouse inner ear. The breakthrough suggests that a new therapy may be developed in the future to successfully treat hearing loss. ... > full story
Magmatically Triggered Slow Earthquake Discovered At Kilauea Volcano, Hawaii (August 30, 2008) -- From June 17-19, 2007, Kilauea experienced a new dike intrusion, where magma rapidly moved from a storage reservoir beneath the summit into the east rift zone and extended the rift zone by as much as 1 meter. ... > full story
Novel Approach In Molecular Differentiation Of Prion Strains (August 30, 2008) -- Scientists have identified a prion protein characteristic that is unique to some natural but unusual sheep scrapie cases. This finding may provide a novel method by which to study prion diversity and their possible changes during cross-species transmission. ... > full story
Antarctic Research Helps Shed Light On Climate Change On Mars (August 30, 2008) -- Eroded gullies on the flanks of Martian craters may have been formed by snowmelt as recently as a few hundred thousand years ago and in sites once occupied by glaciers. Similar conditions can be found in Antarctica's McMurdo Dry Valleys. Rather than being a dead planet, the new data are consistent with dynamic climate changes on Mars. ... > full story
Scientists Discover Why Flies Are So Hard To Swat (August 29, 2008) -- Over the past two decades, Michael Dickinson has been interviewed by reporters hundreds of times about his research on the biomechanics of insect flight. One question from the press has always dogged him: Why are flies so hard to swat? "Now I can finally answer," says Dickinson, the Esther M. and Abe M. Zarem Professor of Bioengineering at the California Institute of Technology. ... > full story
Katrina And Rita Provide Glimpse Of What Could Happen To Offshore Drilling If Gustav Hits Gulf (August 29, 2008) -- Shortly after Hurricanes Katrina and Rita hit the US, engineers studied damage done to offshore drilling platforms in the Gulf of Mexico. If tropical storm Gustav strengthens into a Category 3 hurricane, as forecasters are predicting, the damage could be extensive. ... > full story
Unexpected Large Monkey Population Discovered In Cambodia: Tens Of Thousands Of Threatened Primates (August 29, 2008) -- Biologists have discovered surprisingly large populations of two globally threatened primates in a protected area in Cambodia. The report counted 42,000 black-shanked douc langurs along with 2,500 yellow-cheeked crested gibbons in Cambodia's Seima Biodiversity Conservation Area, an estimate that represents the largest known populations for both species in the world. ... > full story
'Pristine' Amazonian Region Hosted Large, Urban Civilization (August 29, 2008) -- They aren't the lost cities early explorers sought fruitlessly to discover. But ancient settlements in the Amazon, now almost entirely obscured by tropical forest, were once large and complex enough to be considered "urban" as the term is commonly applied to both medieval European and ancient Greek communities. ... > full story
Black Raspberries Slow Cancer By Altering Hundreds Of Genes (August 29, 2008) -- New research strongly suggests that a mix of preventative agents, such as those found in concentrated black raspberries, may more effectively inhibit cancer development than single agents aimed at shutting down a particular gene. Researchers examined the effect of freeze-dried black raspberries on genes altered by a chemical carcinogen in an animal model of esophageal cancer. ... > full story
Saving Lives Through Smarter Hurricane Evacuations (August 29, 2008) -- Hundreds of lives and hundreds of millions of dollars could potentially be saved if emergency managers could make better and more timely critical decisions when faced with an approaching hurricane. Now, an MIT graduate student has developed a computer model that could help do just that. ... > full story
Eyes Evolved For 'X-Ray Vision': Forward-facing Eyes Allow Animals To 'See Through' Clutter In The World (August 29, 2008) -- The advantage of using two eyes to see the world around us has long been associated solely with our capacity to see in 3-D. Now, a new study has uncovered a truly eye-opening advantage to binocular vision: our ability to see through things. ... > full story
Natural Chemical From Sea Sponges Induces Death In Cancer Cells Via Unusual Pathway (August 29, 2008) -- A chemical called candidaspongiolide (CAN) inhibits protein synthesis but also kills cancer cells by triggering caspase 12-dependent programmed cell death, according to an article in the Aug. 26 online issue of the Journal of the National Cancer Institute. ... > full story
