Existing urban water systems are at the end of their design lifetimes. New, innovative solutions are needed, and these must combine technology and engineering with an understanding of social systems and institutions. Fuente : http://www.eurekalert.org/pub_releases/2013-08/mal...

One of two of NASA's Global Hawk unmanned aircraft flew over the remnants of Tropical Storm Erin and investigated the Saharan Air Layer in the Eastern Atlantic Ocean on Aug. 20 and 21. The instruments aboard the Global Hawk sampled the environment of ex-Erin and revealed an elevated dust layer...

The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year. While the ice will continue to shrink until around mid-Sept., it is unlikely that this year's summer low...

The cadherin receptor, BT-R3, of Anopheles gambiae reported in this study mediates the killing action of the Cry4B mosquitocidal toxin, which was published in the 2013 April issue of Experimental Biology and Medicine. Characterization of the toxin-receptor complex will facilitate protein design for...

Transplantation stem cells is a potential clinical therapy for repair of spinal cord injury. However, transplanted cells are especially vulnerable due to a lack of sufficient growth factors at the transplant site. The present study demonstrates that Biphasic electrical stimulation (BES) prevents...

Cutting edge optical sensor technology is being used in the Mississippi River basin to more accurately track the nitrate pulse from small streams, large tributaries and ultimately to the Gulf of Mexico. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/e...

A day after the administration released the Hurricane Sandy Rebuilding Task Force progress report, three U.S. federal agencies have announced plans for remapping parts of the East Coast, where Hurricane Sandy altered seafloors and shorelines, destroyed buildings, and disrupted millions of lives last year.

NASA released new photos and video animations depicting the agency's planned mission to find, capture, redirect, and study a near-Earth asteroid. The images depict crew operations including the Orion spacecraft's trip to and rendezvous with the relocated asteroid, as well as astronauts maneuvering through a spacewalk to collect...

Computer simulations could help scientists make sense of a recently observed and puzzling wrinkle in one of nature's most important chemical processes. It turns out that calcium carbonate -- the ubiquitous compound that is a major component of seashells, limestone, concrete, antacids and myriad other substances -- may...

A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology has set a new record for stability. The clocks act like 21st-century pendulums or metronomes that could swing back and forth with perfect timing for a period comparable to the age of the universe. Fuente :...

An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known, according to a new study. The discovery alters understanding of the chemistry that moves manganese and other elements, like oxygen and carbon, through the natural world. Manganese...

People are psychologically hard-wired to believe that products that are damaged or that aren't whole -- such as small or ripped paper or dented cans -- are useless, and this leads users to trash them rather than recycle them. To circumvent overcrowding landfills and environmental problems, researchers say consumers and...

Infectious disease researchers have uncovered components of the SARS coronavirus -- which triggered a major outbreak of severe acute respiratory syndrome in 2002-03 -- that allow it to take over host cells in order to replicate. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/2...

Scientists area studying the impact of Saharan dust on Houston's air quality, and how it might differ from other sources of pollution. The dust is carried across the Atlantic Ocean on trade winds most summers, and research has shown it can be differentiated from other sources of pollution. Fuente :...
