An international team of physicists working at the Antiproton Decelerator (AD) facility at CERN has announced the first controlled production of large numbers of antihydrogen atoms at low energies. After mixing cold clouds of trapped positrons and antiprotons – the antiparticles of the familiar electron and proton – under closely monitored conditions, the ATHENA collaboration has identified antihydrogen atoms, formed when positrons bind together with antiprotons. The results are published online toda

Winter temperatures are on the rise and scientists note this change will actually increase a plant’s exposure to freezing temperatures

Scientists from Agriculture and Agri-Food Canada predict crops will be at a greater risk of winter damage in the future even though the climate will be warmer. Perennial forage crops are grown on more than 40% of the cultivated land in Eastern Canada and other regions of North America, where they constitute the backbone of the livestock industry. The

Eavesdropping among animals influences their behavior, Lee Dugatkin, an evolutionary biologist at the University of Louisville, has found.

Dugatkin and a colleague, Ryan Earley of Georgia State University, studied eavesdropping among male swordtail fish they placed in an experimental tank. They put two fish on one side of a partition and a lone observer male on the other. In some cases, the partitions were clear and in others, opaque.

The fish that could observe their potential adve

For most drinkers, knowing when to say when occurs a lot quicker than they think. A study by Texas A&M University’s Center for Alcohol and Drug Education Studies shows that even a small amount of alcohol – in many cases, as few as one or two beers – can seriously affect judgment and driving decisions.

The study’s bottom line: Even if you’ve consumed very little alcohol, your decision-making skills are hampered more than you realize and the results could be deadly considering

A drug used to help control psychotic behavior in people with schizophrenia holds promise for controlling similar symptoms in the early stages of Alzheimer’s disease, a new study suggests.

What sets this drug – called quetiapine – apart from its contemporary counterparts is its apparent lack of serious side effects, such as confusion, muscle stiffness and imbalance in the joints, said Douglas Scharre, a study co-author and an associate professor of clinical neurology at Ohio State Universit

Why live in a glass house? For diatoms — tiny ocean-dwelling organisms that live in exquisitely ornate glass cases — the benefit turns out to be enormous.

In a paper published in the Sept. 13 issue of Science, Princeton scientists show that diatoms probably depend on glass to survive because the material facilitates photosynthesis. However, their study suggests that this domestic arrangement has a much bigger beneficiary: the entire planet, which owes its present-day, oxygen-rich and carbo
