SALT LAKE CITY – Researchers at the Intermountain Heart Institute at Intermountain Medical Center have developed a new 3-D technology that for the first time allows cardiologists the ability to see the precise source of atrial fibrillation in the heart – a breakthrough for a condition that affects nearly three million Americans.

A team of NIH scientists has developed a new tool to identify broadly neutralizing antibodies (bNAbs) capable of preventing infection by the majority of HIV strains found around the globe, an advance that could help speed HIV vaccine research.

The Aqua satellite provided this satellite image showing a series of hotspots found in the Siberian region of Russia. These hotspots have been categorized as wildfires rather than agricultural fires by the website: http://fires.kosmosnimki.ru/ The popular Kosmosnimki.Ru web resource introduces the "hybrid" view option – map layers over satellite-based image.

WASHINGTON--Researchers at the U.S. Naval Research Laboratory flew their fuel cell powered Ion Tiger unmanned aerial vehicle (UAV) for 48 hours and 1 minute, April 16 to 18, by using liquid hydrogen (LH2) fuel in a new, NRL-developed, cryogenic fuel storage tank and delivery system. This flight shatters their previous record of 26 hours and 2 minutes set in 2009 using the same vehicle, but with gaseous hydrogen stored at 5,000 pounds per square inch (psi).

A University of Southampton professor has carried out the most detailed analysis ever of the archaeological remains of the lost medieval town of Dunwich, dubbed 'Britain's Atlantis'.

Having trouble falling or staying asleep? According to a new study led by a team of researchers at the Johns Hopkins Bloomberg School of Public Health, insomnia may be an important indicator of future hospitalization among middle-aged and older adults. They examined the association between insomnia and use of home healthcare services, nursing homes and hospitalization and found that insomnia symptoms experienced by middle-aged and older adults were associated with greater future use of costly health services.

WEST LAFAYETTE, Ind. – Researchers have created a new tool to detect flaws in lithium-ion batteries as they are being manufactured, a step toward reducing defects and inconsistencies in the thickness of electrodes that affect battery life and reliability.

Athens, Ga. – The sun provides the most abundant source of energy on the planet. However, only a tiny fraction of the solar radiation on Earth is converted into useful energy.

To help solve this problem, researchers at the University of Georgia looked to nature for inspiration, and they are now developing a new technology that makes it possible to use plants to generate electricity.

Social media has revolutionized the way in which people and businesses interact, and it is taking on a growing role in the health care industry. A new UCLA study looking at the use of social media among plastic surgeons found that roughly half of these specialists use social media tools.

Imagine a TV screen that hangs on the wall like a poster and rolls up like a window shade — or a smartphone that can fold up and fit into a pocket. It may sound like science fiction, but those technological marvels are moving closer to reality, thanks to advances toward development of flexible batteries that could power a new genre of electronics devices.

Consumption of whole walnuts or their extracted oil can reduce cardiovascular risk through a mechanism other than simply lowering cholesterol, according to a team of Penn State, Tufts University and University of Pennsylvania researchers.

Subway may promote itself as the "healthy" fast food restaurant, but it might not be a much healthier alternative than McDonald's for adolescents, according to new UCLA research.

In a study published May 6 in the Journal of Adolescent Health, the researchers found that adolescents who purchased Subway meals consumed nearly as many calories as they did at McDonald's. Meals from both restaurants are likely to contribute toward overeating and obesity, according to the researchers.

Researchers from the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have quantified the significant value that concentrating solar power (CSP) plants can add to an electric grid.

Enzymes could break down cell walls faster – leading to less expensive biofuels for transportation – if two enzyme systems are brought together in an industrial setting, new research by the Energy Department's National Renewable Energy Laboratory suggests.

A paper on the breakthrough, "Fungal Cellulases and Complexed Cellulosomal Enzymes Exhibit Synergistic Mechanisms in Cellulose Deconstruction," appears in the current edition of Energy and Environmental Science. Co-authors include five scientists from NREL and one from the Weizmann Institute in Israel.

Programming an implantable cardioverter-defibrillator (ICD) with a long-detection interval compared with a standard-detection interval resulted in a reduction in anti-tachycardia pacing episodes, ICD shocks delivered, and inappropriate shocks, according to a study in the May 8 issue of JAMA.
