Carnegie Mellon Robotized SUV Wins DARPA Urban Challenge

A self-driving SUV called Boss made history by driving swiftly and safely while sharing the road with human drivers and other robots. The feat earned Carnegie Mellon University's Tartan Racing first place in the DARPA Urban Challenge. Officials of the Defense Advanced Research Projects Agency (DARPA) declared Boss the winner of the event, which pitted 11 autonomous vehicles against each other on a...

Statewide Model Of Better, Faster Heart Attack Care

A North Carolina team of doctors, nurses, hospitals and emergency medical service workers has come up with a way to provide faster, more effective treatment for heart attack patients. It doesn't require expensive drugs or fancy new equipment. But it does require competitors to become collaborators, and it calls on everyone involved to "move treatment forward" -- empowering emergency services...

Weight Loss: Not One Size Fits All

There is no "one size fits all" when it comes to weight loss through exercise, says one behavioral scientist. This study shows that despite people doing the same amount of supervised exercise, people lose different amounts of weight, according to the researchers.

Appetite Regulation Molecule Found: Could Lead To Treatments For Obesity And Unwanted Weight Loss

Researchers have developed a novel way to control the extreme weight loss, common in late-stage cancer, which often speeds death. It may soon be possible to prevent this condition, giving people the strength to survive treatment and improve their chances of recovery. Conversely when normal and obese mice are treated with this molecule, they eat less and lose a lot of weight, suggesting that it may...

Diesel Exhaust Associated With Higher Heart Attack, Stroke Risk In Men

Increased roadway pollution produced by diesel fuel in vehicles is leading to a cascade of conditions that could result in heart attack or stroke, researchers suggest. They found that diesel exhaust increased clot formation and blood platelet activity in healthy volunteers -- which could lead to heart attack and stroke.

Evolution: When Are Genes 'Adventurous' And When Are They Conservative?

Taking a chance on an experiment -- this is one of the impulses that drive evolution. Living cells are, from this angle, great subjects for experimentation: Changes in one molecule can have all sorts of interesting consequences for many other molecules in the cell. Such experiments on genes and proteins have led the cell, and indeed all life, on a long and fascinating evolutionary journey.

New Combination Drug Improves Multiple Cholesterol Disorders In Single Pill

Patients treated with a new investigational combination pill showed significant improvements in cholesterol, triglycerides and other key lipids that lead to heart disease. Simcor combines prescription niacin and simvastatin, two FDA-approved medications with established safety profiles, to target good cholesterol (HDL), bad cholesterol (LDL), and triglycerides in a single pill.

Occasional Fasting Associated With Lower Heart Disease Rates

Foregoing food for a day each month stood out among other religious practices in members of the Church of Jesus Christ of Latter-Day Saints, who have lower rates of heart disease than other Americans. Of several factors considered, "fasting was the strongest predictor of lower heart disease risk in the people we surveyed" according to one of the researchers.
