Humidity measurements in the atmosphere are of essential importance, since water vapour, as the most important natural greenhouse gas, has a strong influence on the Earth's atmospheric radiation balance and, thus, decisively influences our climate. In addition, water is responsible for meteorological phenomena such as the formation of clouds and precipitation.

CAMBRIGDE, MA -- In the last decade, theoretical computer science has seen remarkable progress on the problem of solving graph Laplacians — the esoteric name for a calculation with hordes of familiar applications in scheduling, image processing, online product recommendation, network analysis, and scientific computing, to name just a few. Only in 2004 did researchers first propose an algorithm that solved graph Laplacians in "nearly linear time," meaning that the algorithm's running time didn't increase exponentially with the size of the problem.

Systemic lupus erythematosus (SLE) is disease in which the immune system mistakenly attacks healthy tissues, resulting in inflammation and tissue damage.

Scientists at the Universities of Liverpool have found evidence of an ancient micro-continent buried beneath the Indian Ocean.

The ancient continent extends more than 1500 km in length from the Seychelles to the island of Mauritius and contains rocks as old as 2,000 million years, much older than the Indian Ocean which has formed only in the last 165 million years.

The computer is increasingly used to help in complex situations. The latest innovations in this area will be presented by Karlsruhe Institute of Technology (KIT) and the FZI Research Center for Information Technology at the CeBIT in early March (hall 9, stand G33). User-friendly systems display all facts to surgeons during operation and simultaneously translate university lectures for foreign students. In addition, smart living environments that support comfort, safety, and care services and software for the relocation of e-mails will be presented.

WASHINGTON (Feb. 28, 2013) –The American College of Cardiology and the Heart Rhythm Society, along with key specialty societies, today released appropriate use criteria for implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy (CRT). The document provides assessed levels of appropriateness for implanting the devices in 369 real-life clinical scenarios, with the goal of enhancing physician and patient decision making and improving care and health outcomes.

Much to the chagrin of parents who think their kids should spend less time playing video games and more time studying, time spent playing action video games can actually make dyslexic children read better. In fact, 12 hours of video game play did more for reading skills than is normally achieved with a year of spontaneous reading development or demanding traditional reading treatments.

Improving housing can improve health, particularly when interventions are targeted at those in the poorest health, according to a systematic review published in The Cochrane Library. The authors say their review underscores the importance of targeting those most in need when devising programmes for housing improvement.

DETROIT – A team of researchers led by Shawn P. McElmurry, Ph.D., P.E., assistant professor of civil and environmental engineering in Wayne State University's College of Engineering, has confirmed that seasonal fluctuations in blood lead levels found in children in urban areas throughout the United States and elsewhere in the northern hemisphere are the result of resuspended dust contaminated with lead.

Yttria stabilized zirconia, also known as YSZ, is a material of great interest because of its relatively high oxygen-ion based conductivity. In particular, it finds applications in electrochemical devices, such as solid oxide fuel cells and oxygen sensors. In a study published in EPJ B, Kia Ngai, from the University of Pisa in Italy, and colleagues from the Complutense University in Madrid, Spain, devised a model of the oxygen-ion dynamics that contribute to the conductivity of YSZ.

Millions of tons of food are thrown away each year because the 'best before' date has passed. But this date is always a cautious estimate, which means a lot of still-edible food is thrown away. Wouldn't it be handy if the packaging could 'test' whether the contents are still safe to eat? Researchers at Eindhoven University of Technology, Universitá di Catania, CEA-Liten and STMicroelectronics have invented a circuit that makes this possible: a plastic analog–digital converter. This development brings plastic sensor circuits costing less than one euro cent within reach.

PITTSBURGH—Football fans have become accustomed to viewing televised games from a dozen or more camera angles, but researchers at Carnegie Mellon University and the University of Electro-Communications (UEC) in Tokyo suggest another possible camera position: inside the ball itself.

Amid efforts to expand production of biofuels, scientists are reporting new estimates that downgrade the amount of additional land available for growing fuel crops by almost 80 percent. Their report appears in the ACS journal Environmental Science & Technology.

Northwestern University's Yonggang Huang and the University of Illinois' John A. Rogers are the first to demonstrate a stretchable lithium-ion battery -- a flexible device capable of powering their innovative stretchable electronics.

No longer needing to be connected by a cord to an electrical outlet, the stretchable electronic devices now could be used anywhere, including inside the human body. The implantable electronics could monitor anything from brain waves to heart activity, succeeding where flat, rigid batteries would fail.

The results are consistent with previous studies from Finland and Sweden and indicate that the association is not confined to Scandinavian populations. However, the authors stress that the risk may still be overestimated, and they call for longer term monitoring of the cohort of children and adolescents exposed to Pandemrix to evaluate the exact level of risk.
