Robust methods for GMO detection ready at hand

A new Reference Report published today by the European Commission's Joint Research Centre (JRC) lists 79 reference methods for GMO analysis which have been validated according to international standards. This Compendium, developed jointly by the European Union Reference Laboratory for Genetically Modified Food and Feed (EU-RL GMFF) and the European Network of GMO Laboratories (ENGL), presents the...

Scientists describe the delicate balance in the brain that controls fear

The eerie music in the movie theater swells; the roller coaster crests and begins its descent; something goes bump in the night. Suddenly, you're scared: your heart thumps, your stomach clenches, your throat tightens, your muscles freeze you in place. But fear doesn't come from your heart, your stomach, your throat, or your muscles. Fear begins in your brain, and it is there -- specifically in an...

'Really?' Only 40,000 Phone 7 Devices Sold the First Day?

First-day sales of 40,000 Windows Phone 7 devices. That's the estimate from a leading financial site, which, if true, could represent a relatively weak U.S. launch for Microsoft's new mobile platform. In the words of Microsoft's current Phone 7 advertising campaign, "Really?" On Tuesday, TheStreet.com reported that figure, citing "a market-research source who tracks phone sales." By contrast,...

Graphic Cigarette Warning Labels Proposed

The federal government hopes new larger, graphic warning labels for cigarettes that include images of corpses, cancer patients, and diseased lungs and teeth will help snuff out tobacco use. The images are part of a new push announced by the Food and Drug Administration and the Department of Health and Human Services on Wednesday to reduce tobacco use, which is responsible for about 443,000...

Scientists Discover Radiation Leaving Whales Sunburned

Scientists say some whale species off the Mexican coast are showing signs of severe sunburn that may be caused by the damaged ozone layer's decreased ability to block ultraviolet radiation. The seagoing mammals would be particularly vulnerable to the sun damage in part because they need to spend extended periods of time on the ocean's surface to breathe, socialize, and feed their young. Since...

Pentagon Can't Explain 'Missile' Off California

The Pentagon said it did not know what created a vapor trail that crossed the skies off the Southern California coast and resembled a missile launch. Video posted on the CBS News Web site shows an object flying through the evening sky Monday that left a large contrail, or vapor trail. A news helicopter owned by KCBS, a CBS affiliate in Los Angeles, shot the video. Pentagon officials on...

Milky Way Galaxy Bracketed by Big Bubbles

Unseen until now, new images released by NASA astronomers Tuesday show the Milky Way galaxy sandwiched by colossal high-energy bubbles, extending from the top and bottom like cosmic-scale eggs. Discovered by the space agency's $500 million Fermi space telescope, the bubbles stretch across half of the galaxy's expanse, until now obscured from detection by the "fog" of gamma rays that normally...

EPA Issues Subpoena to Halliburton on Gas Drilling

The Environmental Protection Agency subpoenaed energy giant Halliburton Tuesday, seeking a description of the chemical components used in a drilling technique called hydraulic fracturing. The EPA said it issued the subpoena after Texas-based Halliburton refused to voluntarily disclose the chemicals used in the controversial drilling practice, also known as "fracking." Halliburton was the only...

Aerosol particles at global view

Of all the pollution that fills our lungs on any given day, the most dangerous is the small stuff. Aerosol particle pollution—airborne solid particles and liquid droplets--comes in a range of sizes. Particles smaller than 2.5 micrometers pose the greatest risk to human health because they are small enough to be breathed deep into the lungs and, in some cases, enter the blood stream. These...

Fossil record receives new timeline

Beginning around 542 million years ago, a profusion of animals with shells and skeletons began to appear in the fossil record. So many life forms appeared during this time that it is often referred to as the "Cambrian Explosion."
