Glimpses of the "gallium anomaly" were first seen in the mid-1990s, but it was first clearly discovered and stated in 2007 by neutrino physicist Carlo Giunti of Italy. The problem is simple to state but potentially very important: about 20% fewer electron neutrinos were seen to be captured by gallium nuclei than expected.

How do combined sewer overflows affect water quality in Philadelphia?

In Philadelphia and many urban areas across the U.S. with sewer systems dating back to the 1800s, more frequent flooding is posing a threat not only to people and property but also to surrounding ecosystems. In these areas, stormwater and sewage drain into the same pipes, which a
