In a massive survey of genetic diversity in maize, also known as corn, researchers across the United States, have developed a gene map that should pave the way to significant improvements in a plant that is a major source of food, fuel, animal feed and fiber around the world.
A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide.
NEW YORK -- Medications frequently given to cancer patients to reduce their risk of anemia are associated with an increased risk of deep vein thrombosis or pulmonary embolism, according to new res
An international team of physicists at Los Alamos National Laboratory has succeeded in using intense laser light to accelerate protons to energies never before achieved.
SAN FRANCISCO -- Highlights of today's Scientific Program of the 2009 American Academy of Ophthalmology (AAO) - Pan-American Association of Ophthalmology (PAAO) Joint Meeting include: John T.
NEW YORK (October 21, 2009) -- A 50-year-old New York woman who was diagnosed with a progressive blinding disease at age 13 was implanted with an experimental electronic eye implant that has partially restored her vision. A team led by Dr. Lucian V.
NEW YORK (Oct. 16, 2009) -- The notion that training teachers in the rigors of hands-on science will directly improve their students' academic performance now has real data behind it: Research assembled over the last decade -- now published in the Oct.
SAN FRANCISCO, CA -- SEPTEMBER 25, 2009 -- Late-breaking data from the landmark HORIZONS-AMI clinical trial, presented at the 21st annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, demonstrated that after two years, in heart attack patients, the use of a drug-eluting stent (paclitaxel) was safer and more effective than a bare-metal stent; and that the administration
PITTSBURGH -- Regenerative medicine researchers at the University of Pittsburgh received two grants totaling more than $5 million from the National Institutes of Health (NIH) to explore new methods for cultivating replacement cells from existing tissues and organs.
SAN FRANCISCO, CA -- SEPTEMBER 24, 2009 -- Late-breaking results from the PROSPECT clinical trial shed new light on the types of vulnerable plaque that are most likely to cause sudden, unexpected adverse cardiac events, and on the ability to identify them through imaging techniques before they occur.
SAN FRANCISCO, CA -- SEPTEMBER 23, 2009 -- Late-breaking data from SPIRIT IV, a large-scale multi-center study of nearly 4,000 patients in the U.S., shows that an everolimus-eluting stent demonstrated enhanced safety and efficacy in the treatment of de novo native coronary artery lesions when compared to a paclitaxel-eluting stent, and showed that "low late loss" may be achieved with drug-elu
LEWISTON, Idaho -- Temperature differences and slow-moving water at the confluence of the Clearwater and Snake rivers in Idaho might delay the migration of threatened juvenile salmon and allow them to grow larger before reaching the Pacific Ocean.
NEW YORK -- SEPTEMBER 15, 2009 -- Results of a clinical trial published today in Circulation: Cardiovascular Interventions demonstrate that an infusion of blood that is "supersaturated" with oxygen (SS02) can reduce the amount of damaged heart muscle immediately following a life-threatening heart attack.
A new longitudinal study that looks at how low-income parents discipline their young children has found that spanking 1-year-olds leads to more aggressive behaviors and less sophisticated cognitive development in the next two years. Verbal punishment is not associated with such effects, especially when it is accompanied by emotional support from moms.
Previous research has found that children raised in homes without a biological father have sex earlier than children raised in traditional nuclear families. Now a new study that used a novel and complex design to investigate why this is so challenges a popular explanation of the reasons.
