Greenland Ice Core Reveals History of Pollution in the Arctic

New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions.The study, titled "Coal Burning Leaves Toxic Heavy Metal Legacy in the Arctic," was conducted by the Desert Research Institute (DRI), Reno, Nev. and partially funded by the ...

Universally Speaking, Earthlings Share a Nice Neighborhood

We don't have spacecraft to take us outside our solar system--not yet, at least. Still, astronomers thought they had a pretty good understanding of how our solar system formed and in turn, how others formed. In the last dozen years, nearly 300 exoplanets have been discovered. Are the solar systems in which they reside indeed like our own? Without knowledge or observations to the contrary, conventional knowledge said yes. Three Northwestern University researchers questioned that assumption ... More at http://www.nsf.gov/news/news_summ.jsp?cntn_id=112024&govDel=USNSF_51 This is an NSF News item.

The Shape of Things to Come

Instead of using a flat microchip as the light sensor for their new camera, a team of engineers has developed a sensor that is a flexible mesh of wire-connected pixels. The mesh is made from many of the same materials as a standard digital-camera sensor, but has the unique ability to conform to convoluted, irregular surfaces.The technology is already showing promise for photography, as the researchers conformed the array to a hemispherical shape and incorporated the device into ...

NSF Hosts the Second U.S.-China Computer Science Leadership Summit

Approximately 15 professors, deans and other professionals in the computing sciences from the People's Republic of China came to Arlington, Va. last month for a summit with their U.S. counterparts. The one-day meeting gave participants the chance to discuss challenges and opportunities facing computing scholars from both sides of the Pacific, and it reflected the growing level of cooperation between the academic research communities in both countries.The event was organized by the ...

Antarctic Fossils Paint a Picture of a Much Warmer Continent

National Science Foundation-funded scientists working in an ice-free region of Antarctica have discovered the last traces of tundra--in the form of fossilized plants and insects--on the interior of the southernmost continent before temperatures began a relentless drop millions of years ago.An abrupt and dramatic climate cooling of 8 degrees Celsius, over a relatively brief period of geological time roughly 14 million years ago, forced the extinction of tundra plants and insects and ...

Water Refineries?

Using a surprisingly simple, inexpensive technique, chemists have found a way to pull pure oxygen from water using relatively small amounts of electricity, common chemicals and a room-temperature glass of water.Because oxygen and hydrogen are energy-rich fuels, many researchers have proposed using solar electricity to split water into those elements--a stored energy source for when the sun goes down. One of the chief obstacles to that green-energy scenario has been the difficulty of ... More at http://www.nsf.gov/news/news_summ.jsp?cntn_id=111975&govDel=USNSF_51 This is an NSF News item.

Cold and Ice, and Heat, Episodically Gripped Tropical Regions 300 Million Years Ago

Geoscientists have long presumed that, like today, the tropics remained warm throughout Earth's last major glaciation 300 million years ago.New evidence, however, indicates that cold temperatures in fact episodically gripped these equatorial latitudes at that time. Geologist Gerilyn Soreghan of Oklahoma University found evidence for this conclusion in the preservation of an ancient glacial landscape in the Rocky Mountains of western Colorado. Three hundred million years ago, ... More at http://www.nsf.gov/news/news_summ.jsp?cntn_id=112000&govDel=USNSF_51 This is an NSF News item.

Parasites Outweigh Predators in Pacific Coast Estuaries

In a study of parasites living in three estuaries on the Pacific coast of California and Baja California, researchers have determined that biomass of these parasites exceeds that of top predators, in some cases by more than 20 times.Their findings, which could have significant ecological and biomedical implications, appear in this week's issue of the journal Nature.Biomass is the amount of living matter that exists in a given habitat.
