Researchers have conducted a remote reconnaissance of a distant solar system with a new telescope imaging system that sifts through the blinding light of stars. Using a suite of high-tech instrumentation and software called Project 1640, the scientists collected the first chemical fingerprints, or spectra, of this system's four red exoplanets, which orbit a star 128 light years away from Earth. A detailed description of the planets—showing how drastically different they are from the known worlds in the universe—was accepted Friday for publication in The Astrophysical Journal. ...

PASADENA, Calif.—Imagine that the chips in your smart phone or computer could repair and defend themselves on the fly, recovering in microseconds from problems ranging from less-than-ideal battery power to total transistor failure. It might sound like the stuff of science fiction, but a team of engineers at the California Institute of Technology (Caltech), for the first time ever, has developed just such self-healing integrated chips. The team, made up of members of the High-Speed Integrated Circuits laboratory in Caltech's Division of Engineering and Applied Science, ...

This press release is available in Spanish. Pioneering studies by U. S. Department of Agriculture-funded research molecular geneticist Robert A. Waterland are helping explain how the foods that soon-to-be-moms eat in the days and weeks around the time of conception—or what's known as periconceptional nutrition–may affect the way genes function in her children, and her children's health. In an early study, Waterland and co-investigators examined gene function of 50 healthy children living in rural villages in the West African nation of The Gambia. The study has shaped ...

COLUMBUS, Ohio – Scientists have delved deeper into the evolutionary history of the fruit fly than ever before to reveal the genetic activity that led to the development of wings – a key to the insect's ability to survive. The wings themselves are common research models for this and other species' appendages. But until now, scientists did not know how the fruit fly, Drosophila melanogaster, first sprouted tiny buds that became flat wings. A cluster of only 20 or so cells present in the fruit fly's first day of larval life was analyzed to connect a gene known to be active ...

A delay in the summer monsoon rains that fall over the southwestern United States and northwestern Mexico is expected in the coming decades according to a new study in the Journal of Geophysical Research. The North American monsoon delivers as much as 70 percent of the region's annual rainfall, watering crops and rangelands for an estimated 20 million people. "We hope this information can be used with other studies to build realistic expectations for water resource availability in the future," said study lead author, Benjamin Cook, a climate scientist with joint appointments ...

SAN FRANCISCO (March 11, 2013) — Patients who underwent heart bypass surgery without a heart- lung machine did as well one year later as patients whose hearts were connected to a pump during surgery in a study presented today at the American College of Cardiology's 62nd Annual Scientific Session. CORONARY, an international, multicenter trial of on-pump (with a heart-lung machine) versus off-pump bypass surgery, enrolled 4,752 patients already scheduled to undergo a bypass procedure. The study is the largest to compare the two approaches. For the primary endpoint of ...

Research from the University of Maryland School of Medicine has revealed key features in proteins needed for life to function on Mars and other extreme environments. The researchers, funded by NASA, studied organisms that survive in the extreme environment of Antarctica. They found subtle but significant differences between the core proteins in ordinary organisms and Haloarchaea, organisms that can tolerate severe conditions such as high salinity, desiccation, and extreme temperatures. The research gives scientists a window into how life could possibly adapt to exist on ...

SAN FRANCISCO (March 11, 2013) — Older patients did as well after undergoing coronary bypass surgery off-pump as they did with the more costly "on-pump" procedure using a heart-lung machine to circulate blood and oxygen through the body during surgery, according to research presented today at the American College of Cardiology's 62nd Annual Scientific Session. This large, multicenter trial—the German Off-Pump Coronary Artery Bypass Grafting in Elderly Patients, called GOPCABE—was the first to evaluate on-pump versus off-pump bypass surgery among patients aged 75 or older. ...

A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds. Even when both poles of the planet undergo ozone losses during the winter, the Arctic's ozone depletion tends to be milder and shorter-lived than the Antarctic's. This is because the three key ingredients needed for ozone-destroying chemical reactions —chlorine from man-made chlorofluorocarbons (CFCs), frigid temperatures and sunlight— are not usually present in the Arctic at the same time: the ...

On March 2, 2013, NASA's Solar Dynamics Observatory (SDO) entered its semiannual eclipse season, a period of three weeks when Earth blocks its view of the sun for a period of time each day. On March 11, however, SDO was treated to two transits. Earth blocked SDO's view of the sun from about 2:15 to 3:45 a.m. EDT. Later in the same day, from around 7:30 to 8:45 a.m. EDT, the moon moved in front of the sun for a partial eclipse. When Earth blocks the sun, the boundaries of Earth's shadow appear fuzzy, since SDO can see some light from the sun coming through Earth's atmosphere. ...

SAN FRANCISCO (March 11, 2013) — Non-emergency angioplasty performed at hospitals without on-site cardiac surgery capability is no less safe and effective than angioplasty performed at hospitals with cardiac surgery services, according to research presented today at the American College of Cardiology's 62nd Annual Scientific Session. Emergency surgery has become an increasingly rare event following percutaneous coronary intervention (PCI) or angioplasty—a non-surgical procedure used to open narrow or blocked coronary arteries and restore blood flow to the heart. This ...

OAK BROOK, Ill. – A single concussion may cause lasting structural damage to the brain, according to a new study published online in the journal Radiology.

Slender bacterial nanowires require certain key amino acids in order to conduct electricity, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology, on Tuesday, March 12. In nature, the bacterium Geobacter sulfurreducens uses these nanowires, called pili, to transport electrons to remote iron particles or other microbes, but the benefits of these wires can also be harnessed by humans for use in fuel cells or bioelectronics. The study in mBio® reveals that a core of aromatic amino acids are required to turn ...

San Diego, CA, March 12, 2013 – A new study from the Department of Nutrition, University of North Carolina at Chapel Hill reports that sugar-sweetened beverages (SSBs) are primarily responsible for higher caloric intakes of children that consume SSBs as compared to children that do not (on a given day). In addition, SSB consumption is also associated with higher intake of unhealthy foods. The results are published in the American Journal of Preventive Medicine. Over the past 20 years, consumption of SSBs — sweetened sodas, fruit drinks, sports drinks, and energy drinks ...

Infant girls exposed to high levels of the pesticide DDT while still inside the womb are three times more likely to develop hypertension when they become adults, according to a new study led by the University of California, Davis. Previous studies have shown that adults exposed to DDT (dichlorodiplhenyltrichloroethane) are at an increased risk of high blood pressure. But this study, published online March 12 in Environmental Health Perspectives, is the first to link prenatal DDT exposure to hypertension in adults. Hypertension, or high blood pressure, is a ...
