Dieters know the powerful temptations of just seeing or smelling food. Certain odors might have such a strong effect as to actually change the body's metabolism and lead to an early grave. At least, that's the case for fruit flies on a diet, according to Science Now.
Over the past decade, those who wished to contribute to SETI's mission of locating life elsewhere in the universe could leave their computers on running a special screensaver and donate their unused computing power to the cause. Now, SETI director Jill Tarter is asking people around the globe to get more involved in the Search for Extraterrestrial Intelligence by opening up SETI's servers to the public calling for a worldwide, open source contribution to the search.
Nanotechnology's bright future has finally come up with a possible treatment for the dreaded pimples of our teen years. That has arrived in the form of gold nano-bombs which deliver a lethal dose of lauric acid to skin-dwelling bacteria responsible for that unsightly acne, according to UPI.
War veterans suffering from post-traumatic stress disorder have found unexpected relief from the banned drug MDMA, known more commonly as ecstasy. The psychedelic drug typically associated with hard-partying clubbers appears to cure PTSD entirely in some cases, Scientific American reports.
More than three months after being hurled into orbit, NASA's Solar Dynamics Observatory is snapping some breathtaking images of the Sun, the first of which NASA released this afternoon. The mission designers have to be happy with them: the pics capture huge looping prominences lashing out from the surface and the kinds of massive explosions one might expect from a giant, churning ball of cosmic gas.
When we think of farming energy, we generally think of feedstocks like corn that can be processed into ethanol, or perhaps other plant life we can culture and harvest like algae. But don't underestimate the livestock; we've recently seen methane-trapping schemes that can power farms and giant cattle treadmills that turn idle dairy drones into power-producing machines.
The initial fallout from a chemical or radiological attack would be devastating enough, but the cleanup of such an incident would be equally hazardous. While HAZMAT teams and other authorities have methods of scrubbing radiological and chemical waste, the porous nature of building materials like concrete gives radionuclides and dangerous chemical agents plenty of places to hide from conventional cleanup methods.

Every day for the past three years, 600 or so additional British citizens file into medical offices around the country. They are responding to a letter, stamped “BioBank” in blue letters, that begins: “We are writing to ask for your help in studying the prevention and treatment of cancer, heart attacks, strokes, diabetes, dementia, and many other serious diseases.” The British government wants to collect peoples’ blood, urine and saliva; measure their waistlines and heart rates; sequence their DNA; and ask them questions like “How hot do you drink your tea?”
A large Cold War supply of helium-3 has begun to rapidly run out, due to heavy demand from U.S. scientists who need the gas for neutron detectors and cryogenic experiments. Almost 60,000 liters of helium-3 were used in 2007 and 2008, compared to just 10,000 liters used annually about 10 years ago. A House subcommittee has been convened to search for a solution this week, New Scientist reports.
It's good to know that Wisconsin state legislators can overcome partisan divisions and a host of pressing issues to jointly select an official state microbe -- the Lactococcus lactis bacterium responsible for helping make delicious cheddar, Colby and Monterey Jack cheese. That makes Wisconsin the first U.S. state to bestow such an honor upon a microbe, the New York Times reports.
