Why are some species of plants and animals favored by natural selection? And why does natural selection not favor other species similarly?   view more (2008-11-04)

Mouse studies suggest daily dose of ginkgo may prevent brain cell damage after a stroke
Working with genetically engineered mice, researchers at Johns Hopkins have shown that daily doses of a standardized extract from the leaves of the ginkgo tree can prevent or reduce brain damage after an induced stroke.   view more (2008-10-10)

Researchers note differences between people and animals on calorie restriction
Calorie restriction, a diet that is low in calories and high in nutrition, may not be as effective at extending life in people as it is in rodents, according to scientists at Washington University School of Medicine in St. Louis.   view more (2008-09-25)

People with type 2 diabetes can put fatty livers on a diet with moderate exercise
Weekly bouts of moderate aerobic exercise on a bike or treadmill, or a brisk walk, combined with some weightlifting, may cut down levels of fat in the liver by up to 40 percent in people with type 2 diabetes, a study by physical fitness experts at Johns Hopkins shows.   view more (2008-09-22)

A Little Nitrogen Can Go a Long Way
Varying the rate of crop production inputs such as fertilizer and seed makes intuitive sense, as farmers have long observed differences in crop yield in various areas of a single field. The availability of spatial yield information from combines equipped with yield monitors has provided a good... view more (2008-09-04)

Vitamin C injections slow tumor growth in mice
High-dose injections of vitamin C, also known as ascorbate or ascorbic acid, reduced tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian, and pancreatic cancers, researchers from the National Institutes of Health (NIH) report in the August 5, 2008, issue of the... view more (2008-08-05)

Golden Scales: Nanoscale Mass Sensor from Berkeley Can Be Used to Weigh Individual Atoms and Molecules
There's a new "gold standard" in the sensitivity of weighing scales. Using the same technology with which they created the world's first fully functional nanotube radio, researchers with Berkeley Lab and the University of California (UC) at Berkeley have fashioned a nanoelectromechanical... view more (2008-07-29)

'HiCy' drug regimen reverses ms symptoms in selected patients
A short-term, very-high dose regimen of the immune-suppressing drug cyclophosphamide seems to slow progression of multiple sclerosis (MS) in most of a small group of patients studied and may even restore neurological function lost to the disease, Johns Hopkins researchers report.   view more (2008-06-11)

Mercury contamination found in stranded Victorian dolphins
Monash University research into heavy metal contaminant levels in dolphins from Port Phillip Bay and the Gippsland Lakes has revealed high mercury levels may be a contributing factor to dolphin deaths.   view more (2008-06-10)

Study shows long-term weight control is achievable

Sandia weighs in on new definition for kilogram
The kilogram is losing weight and many international scientists, including some at Sandia National Laboratories, agree that it's time to redefine it.   view more (2008-02-29)

Crystal bells stay silent as physicists look for dark matter
Scientists of the Cryogenic Dark Matter Search experiment today announced that they have regained the lead in the worldwide race to find the particles that make up dark matter.
