Software tracks source of fecal pollution in water

Posted: 12 Jun 2015 06:13 AM PDT

Scientists have developed a new piece of software to predict the source of fecal pollution in seas, reservoirs and rivers. The system, called Ichnaea, uses the automatic learning and analysis of various biological indicators to make highly reliable predictions of this type of pollution, which poses a serious health risk. Fecal pollution is increasingly more common in rivers and water reserves.

Viral protein helps Epstein-Barr virus-infected B cells escape human killer T cells

Posted: 11 Jun 2015 11:42 AM PDT

About 90 percent of adults worldwide are infected with Epstein-Barr virus, or EBV. The virus infects B cells (the white blood cells that make antibodies) and can contribute to B-cell-derived cancers, but in most people it remains dormant -- a state scientists refer to as 'latent infection' -- for the rest of their lives. A new study sheds new light on why the infected person's immune system cannot eliminate EBV, or the associated cancer risk.

Wireless researchers call for reformed safety standards for wireless devices
