| New insight into accelerating summer ice melt on the Antarctic Peninsula Posted: 14 Apr 2013 04:34 PM PDT A new 1,000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost 10-fold, and mostly since the mid-20th century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. |
| Nanosponges soak up toxins released by bacterial infections and venom Posted: 14 Apr 2013 04:34 PM PDT Engineers have invented a "nanosponge" capable of safely removing a broad class of dangerous toxins from the bloodstream -- including toxins produced by MRSA, E. coli, poisonous snakes and bees. |
| Posted: 14 Apr 2013 04:34 PM PDT Bioengineered rat kidneys successfully produced urine both in a laboratory apparatus and after being transplanted into living animals. The research team built functional replacement kidneys on the structure of donor organs from which living cells had been stripped, an approach previously used to create bioartificial hearts, lungs and livers. |
| Recent Antarctic climate, glacier changes at the 'upper bound' of normal Posted: 14 Apr 2013 04:31 PM PDT In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise. New ice core research suggests that, while the changes are dramatic, they cannot be attributed with confidence to human-caused global warming. |
| Ordinary skin cells morphed into functional brain cells Posted: 14 Apr 2013 04:31 PM PDT Researchers have discovered a technique that directly converts skin cells to the type of brain cells destroyed in patients with multiple sclerosis, cerebral palsy and other so-called myelin disorders. |
| Cutting specific pollutants would slow sea level rise, research indicates Posted: 14 Apr 2013 04:31 PM PDT With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow down sea level rise. Reductions in the four pollutants that cycle comparatively quickly through the atmosphere could forestall the rate of sea level rise by roughly 25 to 50 percent. |
