The melting of an Antarctic ice sheet roughly 14,000 years ago triggered a period of warming in Europe that marked the beginning of the end of the Earth’s last ice age, says a new study.
A paper in the March 14 issue of the journal Science suggests that a catastrophic collapse of an Antarctic ice sheet dumped roughly a million cubic litres per second of freshwater into the southern oceans, changing the climate thousands of kilometres to the north and ushering in a dramatic climate shift kn
Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial “sinks” to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees, either at home or in developing countries. But how efficient is this “carbon trading” and how good are forests at absorbing these extra carbon emissions?
Nearly one hundred of the world’s leading experts on globa
New data suggests that a novel molecule appears to be involved in the intestine’s response to infection. The study was a collaboration between researchers at Washington University School of Medicine in St. Louis and the Institut Curie in Paris. It appears in the March 13 issue of the journal Nature.
“This is the first identified function for this molecule,” says co-senior author Susan Gilfillan, Ph.D., research instructor in pathology and immunology at the School of Medicine. “Our findings s

Sleep: Don’t be too sure you’re getting enough of it.
Those who believe they can function well on six or fewer hours of sleep every night may be accumulating a “sleep debt” that cuts into their normal cognitive abilities, according to research conducted at the University of Pennsylvania School of Medicine. What’s more, the research indicates, those people may be too sleep-deprived to know it.
A highly sensitive, inexpensive “lab-on-a-chip” that provides warning within seconds of even trace amounts of toxic chemicals in water was designed and demonstrated recently by National Institute of Standards and Technology (NIST) scientists and collaborators.
The prototype sensor system monitors the natural response of bacterial cells bound within the microscopic channels of a plastic microfluidics device–a miniaturized chemical and biochemical analysis system. In the presence of certain
The Goualougo Triangle, nestled between two rivers in a Central African rain forest, is so remote that primate researchers who traveled 34 miles, mostly by foot, from the nearest village through dense forests and swampland to get there, have discovered a rare find: chimpanzees that have had very little or no contact at all with humans.
The chimpanzees’ behavior when first coming in contact with the researchers was a telltale sign of lack of human exposure — the chimpanzees didn’t run and
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
