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.
The European Commission draft still needs approval from the European Parliament and governments of the 27 member countries - since the majority of the EU countries that were signatories to the Kyoto Treaty are not in compliance the new law could have devastating effects.
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.
A study at UCL (University College London) finds that a high-prevalence of male-killing bacteria active in many species of insect including the butterfly, actually increases female promiscuity and male fatigue.
The study was carried out on Hypolimnas bolina butterflies in Pacific Island and South-East Asian populations. The islands provide an ideal location because every island is differently affected by the male-killling bacteria so that each has a different ratio of males to females.

New research findings may help refine the accepted models used by earth scientists over the past 30 years to describe the ways in which continents clash to form the Earth's landscape.
Debate over euthanasia continues in many countries. Opinions were divided for months in Italy over the case of Piergiorgio Welby, who died Dec. 20 when he was administered a sedative and his artificial respiration was turned off.
More recently, in Australia, cancer sufferer John Elliot traveled to Zurich, Switzerland, to put an end to his life with the aid of the organization Dignitas. As often happens with these cases, pro-euthanasia activists exploited the emotional appeal of a suffering and terminally ill patient to push for a so-called right to die.
The researchers at West Virginia University say a computerized approach to counting punches at ringside identifies certain characteristics related to deaths in the ring.

People feeling sad tend to eat more of less-healthy comfort foods than when they feel happy, finds a new study co-authored by a Cornell food marketing expert. However, when nutritional information is available, those same sad people curb their hedonistic consumption. But happier people don't.
