Bioengineered rat kidneys developed by Massachusetts General Hospital investigators 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...

A new 1000-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. Fuente : http://www.eurekalert.org/pub_releases/2013-04/bas...

Engineers at the University of California, San Diego 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.

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. Fuente :...

A new study from Mount Sinai researchers to be published in Nature Genetics identifies 14 new genes that are associated with heart rate and may provide insight into the treatment of cardiovascular disease. Since heart rate is a marker of cardiovascular health, these findings could provide a better understanding of genetic...

In recent decades glaciers at the edge of Antarctica have thinned and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise. New ice core research led by the University of Washington indicates that the changes, though dramatic, cannot be confidently attributed to human-caused...

CRISPR, a system of genes that bacteria use to defend themselves against viruses, has been found to be involved in helping some bacteria evade the mammalian immune system. Scientists have shown that Francisella novicida, a close relative of the bacterium that causes tularemia, and another bacterium that causes meningitis, need...

A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for electric cars, reports a University of Arizona-led team. The team has successfully used the new plastic to make lithium-sulfur batteries. The team's discovery could provide a new use for the sulfur left over when oil and...
