Toxic mercury, accumulating in the Arctic, springs from a hidden source
Environmental scientists at Harvard have discovered that the Arctic accumulation of mercury, a toxic element, is caused by both atmospheric forces and the flow of circumpolar rivers that carry the element north into the Arctic Ocean. View More (2012-05-21)

Lunar Reconnaissance Orbiter's LAMP reveals lunar surface features
New maps produced by the Lyman Alpha Mapping Project aboard NASA's Lunar Reconnaissance Orbiter reveal features at the Moon's northern and southern poles in regions that lie in perpetual darkness. LAMP, developed by Southwest Research Institute® (SwRI®), uses a novel method to peer into these so-called permanently shadowed regions (PSRs), making visible the invisible. View More (2012-01-16)

Earth's massive extinction: The story gets worse
Scientists have uncovered a lot about the Earth's greatest extinction event that took place 250 million years ago when rapid climate change wiped out nearly all marine species and a majority of those on land. Now, they have discovered a new culprit likely involved in the annihilation: an influx of mercury into the eco-system. View More (2012-01-06)
Upper atmosphere facilitates changes that let mercury enter food chain
Humans pump thousands of tons of vapor from the metallic element mercury into the atmosphere each year, and it can remain suspended for long periods before being changed into a form that is easily removed from the atmosphere. View More (2011-12-19)
Mercury releases into the atmosphere from ancient to modern times
In pursuit of riches and energy over the last 5,000 years, humans have released into the environment 385,000 tons of mercury, the source of numerous health concerns, according to a new study that challenges the idea that releases of the metal are on the decline. View More (2011-12-15)
Huskies lend insight into mercury risk
