Demonstrating that chemistry sometimes can inform history, researchers from the National Institute of Standards and Technology (NIST), Colorado College and Mount Saint Mary's University in Emmitsburg, Md., have shown that sensitive nondestructive evaluation (NDE) techniques can be used to determine the elemental composition of ancient coins, even coins that generally have been considered too corroded for such methods*.

GREENBELT, Md. -- NASA engineers have begun building hardware for a new Landsat satellite instrument that helps monitor water consumption — an important capability in the U.S. West where precipitation is sparse and water rights are allocated — now that they have passed an independent review of the instrument's design and integration and testing methods.
CORAL GABLES, FL (May 26, 2010)--A team of researchers at the University of Miami (UM) has developed a computer model for finding and projecting in time sunken oil masses on the bottom of bays, after an oil spill. The unique model can be used in oil spill planning, response, and recovery applications.
CORVALLIS, Ore. – Researchers at Oregon State University have made an important fundamental advance in robotics, in work that should lead toward robots that not only can walk and run effectively, but use little energy in the process.
CHAMPAIGN, lll. — Researchers at the University of Illinois have developed a new, more accurate method of calculating the change in greenhouse gas emissions that results from changes in land use.
The new approach, described in the journal Global Change Biology, takes into account many factors not included in previous methods, the researchers report.
CHICAGO -- Aggressive treatment of anaplastic thyroid carcinoma has dramatically increased survival in the small group of patients who chose to undergo it, say physicians at Mayo Clinic. Their findings will be presented at the annual meeting of the American Society of Clinical Oncology, to be held June 4-8 in Chicago.
'This is sad news considering Denmark has always been praised as the benchmark in Europe in terms of access and availability of treatment for patients seeking ART' said Dr. Søren Ziebe from the University Hospital in Copenhagen, Executive Committee Member of ESHRE and the SIG coordinator of all SIGs at ESHRE.
Denmark until now provided reimbursement for assisted reproduction treatments (ART) with up to three treatment trials for married and unmarried couples, singles and homosexuals.
The first new projections of future aircraft emissions in 10 years predicts that carbon dioxide and other gases from air traffic will become a significant source of global warming as they double or triple by 2050. The study is in ACS' Environmental Science & Technology, a semi-monthly journal.
ROCHESTER, Minn. -- In the May issue of Mayo Clinic Proceedings, physician experts review current practices for pain management in cirrhotic patients. The physician experts reviewed all current literature available on PubMed and MEDLINE with no limits in the search to recommend a uniform and practical guide to approaching analgesia in the cirrhotic patients.
Imagine you could work out the answer to a question, without knowing what the question was. For example, suppose someone thinks of two numbers and then asks another person to work out their sum, without letting them know what the two numbers are. However, they are given an encryption of the two numbers but not told how to decrypt them.
Providing single lens distance glasses to older people who wear multifocal glasses and who regularly take part in outdoor activities is a simple and effective way of preventing falls, concludes a study published on bmj.com today.
However, the researchers warn that this strategy may not be appropriate for frailer people who spend more time indoors.
Fish alter their movements when under threat from predators to keep closer together and to help them to blend into the crowd, according to new research headed by scientists at the University of York.
Researchers in the York Centre for Complex Systems Analysis (YCCSA), based in the University's Department of Biology, used a combined computer simulation and experimental study of group behaviour to discover that shoaling fish co-ordinate their movements more frequently when under threat.
CAMBRIDGE, Mass. -- The majestic animals most closely associated with the African savanna -- fierce lions, massive elephants, towering giraffes -- may be relatively minor players when it comes to shaping the ecosystem.
