The Lancet Recants Study Linking Autism To Vaccine 590

JamJam writes "The Lancet, a major British medical journal, has retracted a flawed study linking the measles, mumps, and rubella vaccine to autism and bowel disease. British surgeon and medical researcher Andrew Wakefield and his colleagues originally released their study in 1998. Since then 10 of Wakefield's 13 co-authors have renounced the study's conclusions and The Lancet has said it should never have published the research. Wakefield now faces being stripped of his right to practice medicine in Britain. The vaccine-autism debate should now end."

A Hyper-Velocity Impact In the Asteroid Belt? 114

astroengine writes "Astronomers have spotted something rather odd in the asteroid belt. It looks like a comet, but it's got a circular orbit, similar to an asteroid. Whether it's an asteroid or a comet, it has a long, comet-like tail, suggesting something is being vented into space. Some experts think it could be a very rare comet/asteroid hybrid being heated by the sun, but there's an even more exciting possibility: It could be the first ever observation of two asteroids colliding in the asteroid belt."

Supercomputer Adds Credence to Standard Model 120

ScienceDaily is reporting that researchers at the University of Edinburgh and Southampton in cooperation with partners from Japan and the US have shed some light on the Standard Model of physics using a new computer model. "The project's enormously complex calculations relate to the behavior of tiny particles found in the nuclei of atoms, known as quarks. In order to carry out these calculations, the researchers first designed and built a supercomputer that was among the fastest in the world, capable of tens of trillions of calculations per second. The computations themselves have taken a further three years to complete. Their result shows that the Standard Model's claim to be the best theory invented holds firm. It raises the stakes for the riddle to be solved by experiments at the Large Hadron Collider at CERN, which will switch on later this year. Physicists' efforts to confront Standard Model predictions using the most powerful computers available with the most precise experiments offer no clues about what to expect."

Astronomers Explode Virtual Supernova 97

DynaSoar writes "Scientists at the University of Chicago's Center for Astrophysical Thermonuclear Flashes have created a simulation of a white dwarf exploding into a type 1a supernova. Using 700 processors and 58,000 hours, they produced a three second movie showing the initial burst that is thought to be the source of much of the iron in the universe. Understanding these supernovas is also important to testing current cosmological theories regarding dark matter and dark energy, as their brightness is used as a measurement of distance, and discrepancies found in the brightness of very distant supernovas consistently seem to indicate a change in the speed of expansion of the universe over time."
