Two of Greenland's largest glaciers shrank dramatically and dumped twice as much ice into the sea during a period of less than a year between 2004 and 2005. And then, less than two years later, they returned to near their previous rates of discharge.
Fermions tend to avoid each other and cannot "travel" in close proximity. Demonstrated by a team at the Institut d'optique (CNRS/Université Paris 11, Orsay-Palaiseau), this result is described in detail in the January 25, 2007 issue of Nature. It marks a major advance in our understanding of phenomena at a quantum scale.
A Michigan scientist who was put on academic trial for teaching evolution at Calvin College in the 1980s is emerging as a national figure in the cultural war over faith and science.
On Wednesday, Dr. Howard Van Till was one of four scholars from across the country who debated faith and evolution at a conference at Grove City College, a Christian liberal arts school near Pittsburgh.
And Sunday, he will lecture at Kirk in the Hills Presbyterian Church in Bloomfield Hills.
They said last week they would make environmental crime a part of European law and they may have done it.

Whether in the form of sensors in the refrigerator which automatically order more milk or in the car sounding an alarm when the driver starts to become drowsy, "Ambient Intelligence" is the next computer technology revolution. But networked objects equipped with intelligence will only be able to establish themselves if they take proper consideration of users' misgivings, in particular with regard to data protection.
Using artificial atoms on a chip, Yale physicists have taken the next step toward quantum computing by demonstrating that the particle nature of microwave photons can now be detected, according to a report spotlighted in the February 1 issue of the journal Nature.
Archaeologists are now turning to forensic crime lab techniques to hunt for dyes, paint, and other decoration in prehistoric textiles.
Temperatures are rising on Earth, which is heating up the debate over global warming and the future of our planet, but what may be needed most to combat global warming is a greater focus on adapting to our changing planet, says a team of science policy experts writing in this week's Nature magazine.
Sucrose plays a vital role in coffee organoleptic quality. A team from CIRAD and the Agricultural Institute of Paraná in Brazil has recently identified the genes responsible for sucrose accumulation in coffee beans. This is a new step along the way to producing exceptional coffees.The sucrose accumulated in the beans is one of the organoleptic compounds in coffee. (Photo Credit: Pierre Marraccini, CIRAD)
We may not be as fit as the people of ancient Athens, despite all that modern diet and training can provide, according to research by University of Leeds exercise physiologist, Dr Harry Rossiter.
