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.

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.
