A new study using a computer climate model to simulate the last 50 years of climate changes, projects warming over the next 50 years regardless of whether or not nations curb their greenhouse gas emissions soon. If no emission reductions are made and they continue to increase at the current rate, global temperatures may increase by 1-2 degrees Celsius [2-4 degrees Fahrenheit]. But if the growth rate of carbon dioxide does not exceed its current rate and if the growth of true air pollutants (substance

The Swedish Radiation Protection Authority has engaged two internationally well-known epidemiologists to review published epidemiological studies on the relationship between the use of cellular telephones and cancer risk. They are Dr. John D. Boice, Jr. and Dr. Joseph K. McLaughlin from the International Epidemiology Institute, USA.

In their review, no consistent evidence was observed for increased risk of brain cancer, meningioma, acoustic neurinoma, ocular melanoma, or salivary gland canc

Scientists are developing a method that could prevent lung infections in people who smoke, according to a paper presented today (Wednesday 18 September) at the Society for General Microbiology autumn meeting at Loughborough University.

“We’ve used a human tissue model to show how we can prevent Mycobacterium avium complex (MAC) bacteria from invading cells in the lungs. These bacteria attach themselves to mucus and damaged tissue lining the lungs, and often cause infections in people with ex

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
