New options for nuclear waste? Crushing pressure surprisingly opens up nanopores in mineral Posted: 04 Apr 2012 11:41 AM PDT By squeezing a porous solid, scientists surprisingly made its cavities open wider, letting in — and trapping — europium ions. Given the similarities between europium and uranium ions, the team thinks the innovation could represent a promising new avenue for nuclear waste processing.

Posted: 04 Apr 2012 10:38 AM PDT Climate scientists have proposed a simple new mechanism to explain the source of carbon that fed a series of extreme warming events about 55 million years ago, the Paleocene-Eocene Thermal Maximum, and a sequence of similar, smaller warming events afterward.

Growing nitrous oxide levels explained Posted: 04 Apr 2012 07:29 AM PDT Scientists have generated a 65-year record of Southern Hemisphere nitrous oxide measurements, establishing a new benchmark against which to compare changes in the long-lived greenhouse gas that is also a major ozone-depleting substance.

Vegetation cover affects the speed of snowmelt in tundra regions Posted: 04 Apr 2012 07:22 AM PDT Climate change has increased vegetation in Arctic tundra regions. According to a recent study, the increase in vegetation in tundra regions may further accelerate global warming.
