DNA testing carried out by University of Leicester geneticists and funded by The Wellcome Trust has thrown new light on the ancestry of one of the USA’s most revered figures, the third President, Thomas Jefferson.
Up to 10 percent of women newly diagnosed with cancer in one breast develop cancer in the opposite breast. Results of a major clinical trial show that magnetic resonance imaging (MRI) scans are highly effective tools for quickly identifying these opposite breast cancers, detecting diseased tissue that other screening methods missed.
A recent NASA study suggests that tiny dust particles may have foiled forecasts that the 2006 hurricane season would be another active one.
Scientists at Brookhaven National Laboratory are trying to design catalysts inspired by photosynthesis, the natural process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a bio-inspired system that can produce fuels like methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy.
Behind every wave of disgust that comes your way may be a biological imperative much greater than the urge to lose your lunch, according to a growing body of research by a UCLA anthropologist.
In an effort to improve health, many popular foods are undergoing a more nutritious make-over. Now, a team of food chemists at the University of Maryland has discovered how to boost the antioxidant content of pizza dough by optimizing baking and fermentation methods, a finding that could lead to healthier pizza, they say.
An odd, six-sided, honeycomb-shaped feature circling the entire north pole of Saturn has captured the interest of scientists with NASA’s Cassini mission.
Scientists at the MIT Media Lab have invented a way to reversibly silence brain cells using pulses of yellow light, offering the prospect of controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson’s disease.
Percutaneous coronary intervention plus optimal medical therapy does not improve outcomes in patients with coronary artery disease, compared with optimal medical therapy alone, according to study results presented yesterday at the 56th Annual Scientific Session of the American College of Cardiology in New Orleans, and published online in the New England Journal of Medicine.
A new climate modeling study forecasts the complete disappearance of several existing climates in tropical highlands and regions near the poles, while large swaths of the tropics and subtropics may develop new climates unlike any seen today.
Researchers at the University of Southampton have developed a software package for modelling asteroid impacts that enables them to assess the potential human and economic consequences across the globe. Among those most at risk: China, the U.S. and Japan.
You’re high above the desert peaks. Your aircraft are approaching their targets. Information from instruments, cameras and radar is before your eyes. And with the help of 100 million pixels of bright and vivid virtual reality you’re in control of a swarm of U.S. Air Force unmanned aerial vehicles.
Researchers at the U.S. Department of Energy’s Ames Laboratory are employing some modern day alchemy in an effort to find a material with properties of rare and high-priced palladium. If they’re successful, it could remove a major roadblock from the path of hydrogen fuel-cell powered vehicles.
A minimally invasive procedure known as radiofrequency (RF) ablation is effective for treating lung cancer in patients who are not candidates for surgery, according to a Rhode Island Hospital study published in the April issue of the journal Radiology.
In its first laboratory tests on human tissue, a light-based probe almost instantly detected the earliest signs of cancer in cells that line internal organs.
Most people don’t appreciate an angry look, but a new University of Michigan psychology study found that some people find angry expressions so rewarding that they will readily learn ways to encourage them.
Juicing up your cell phone or iPod may take on a whole new meaning in the future. Researchers at Saint Louis University in Missouri have developed a fuel cell battery that runs on virtually any sugar source — from soft drinks to tree sap — and has the potential to operate three to four times longer on a single charge than conventional lithium ion batteries, they say.
