A set of maps created by the University of Sheffield have illustrated, for the first time, how our last British ice sheet shrunk during the Ice Age.

Led by Professor Chris Clark from the University's Department of Geography, a team of experts developed the maps to understand what effect the current shrinking of ice sheets in parts of the Antarctic and Greenland will have on the speed of sea level rise.

LOS ANGELES, Feb. 10, 2011 — Young, uninsured stroke survivors or those covered by the Medicare Part D drug benefit often can't afford medications — increasing the risk for future strokes or other cardiovascular disease-related events, according to research presented at the American Stroke Association's International Stroke Conference 2011.

Ancient stone faces carved into the walls of a well-known limestone cave in East Timor have been discovered by a team searching for fossils of extinct giant rats.

The team of archaeologists and palaeontologists were working in Lene Hara Cave on the northeast tip of East Timor.

"Looking up from the cave floor at a colleague sitting on a ledge, my head torch shone on what seemed to be a weathered carving," CSIRO's Dr Ken Aplin said.

"I shone the torch around and saw a whole panel of engraved prehistoric human faces on the wall of the cave.

COLUMBIA, Mo. – The aging population, 65 years and older, includes nearly 3.8 million divorced men and women, according to the U.S. Census Bureau. Illnesses and end-of-life issues can be particularly difficult for singles without spouses or designated caregivers. A new study from the University of Missouri provides insight into the experiences of exes who care for their former spouses, offering support, assistance with daily tasks and management of health needs.

Forecasters at the Joint Typhoon Warning Center were keeping a close eye on a low pressure area known as System 94S yesterday, and satellite data helped confirm that today it has strengthened into Tropical Storm Bingiza.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Terra satellite captured this image of Tropical Storm Bingiza at 06:30 UTC (1:30 a.m. EST) on its approach to Madagascar. The highest, strongest thunderstorms appeared almost bubble-like near the center of the storm's circulation.

University of Arizona researchers have cracked one of the puzzles surrounding what has been called "the world's most mysterious manuscript" – the Voynich manuscript, a book filled with drawings and writings nobody has been able to make sense of to this day.

Using radiocarbon dating, a team led by Greg Hodgins in the UA's department of physics has found the manuscript's parchment pages date back to the early 15th century, making the book a century older than scholars had previously thought.

ALBUQUERQUE, N.M. — A Sandia National Laboratories team helped reach a major milestone in the nation's nuclear nonproliferation efforts by working with the Central Asian country of Kazakhstan to move nuclear materials — enough to build an estimated 775 nuclear weapons — to safety.

Irvine, Calif., Feb. 10, 2011 – Those light-emitting diodes marketed as safe, environmentally preferable alternatives to traditional lightbulbs actually contain lead, arsenic and a dozen other potentially hazardous substances, according to newly published research.

Therapy in which robots manipulate paralyzed arms, combined with standard rehabilitation, can improve arm and shoulder mobility in patients after stroke, according to research presented at the American Stroke Association's International Stroke Conference 2011.

Young, uninsured stroke survivors or those covered by the Medicare Part D drug benefit often can't afford medications — increasing the risk for future strokes or other cardiovascular disease-related events, according to research presented at the American Stroke Association's International Stroke Conference 2011.

Researchers evaluated whether cost-related non-adherence to medication was a problem for stroke survivors even after the 2006 implementation of Medicare Part D, a federal government drug benefit that offers prescription drug coverage to all Medicare participants.

COLUMBUS, Ohio – A new alloy promises to lessen welders' risk of breathing toxic fumes on the job.

The alloy is a welding "consumable" – the material that melts under the welder's torch to fill the gap between parts that are being joined.

The new nickel alloy consumable is more expensive compared to those already on the market, but worth the cost in situations where adequate ventilation is a problem.

That's why two Ohio State University engineers invented the alloy – specifically to aid military and commercial welding personnel who work in tight spaces.

(WASHINGTON) -- In asymmetric warfare, early detection and identification of trace level chemical and biological agents and explosive compounds is critical to rapid reaction, response, and survivability. While there are many methods currently being used that can detect these threats, none allow for the unique fingerprinting of threat agents at trace levels.

ARLINGTON, Va. - Flight crews responsible for launching aircraft from the decks of carriers are transitioning into the computer age, with the aid of an Office of Naval Research (ONR) TechSolutions effort to move paper tables onto handheld devices.

The Catapult Capacity Selector Valve (CSV) Calculator could eventually eliminate the need for paper-bound launch bulletins. The device underwent final test and evaluation at the end of January aboard USS Harry S. Truman (CVN 75). The Truman's flight deck crew recently underwent training with the Catapult CSV Calculator.

Nairobi, Kenya (9 February 2011) Trees growing on farms will be essential to future development. As the number of trees in forests is declining every year, the number of trees on farms is increasing. Marking the launch of the International Year of Forest by the United Nations Forum on Forests (UNFF9) in New York on 29 January, Dennis Garrity, the Director General of the World Agroforestry Centre, highlighted the importance of mixing trees with agriculture, the practice known as agroforestry.
