How tall are the ice sheets?
By bouncing powerful radar beams from a satellite, a German team of scientists have created very detailed maps of how the height changes across the ice sheets.
Giant cosmic magnifying glass finds baby stars
Like Sherlock with his famous magnifying glass, astronomers use lenses to improve our view of the world -- they use telescopes. And very occasionally, they stumble across an amazing and rare cosmic phenomenon called 'gravitational lensing.' When this happens, a natural cosmic magnifying glass is created, boosting our vision of the universe allowing us to look at distant objects that wouldn't be visible otherwise!
In Brazil, conservation is worth the price tag
Researchers have determined that it would cost Brazil less than 1 percent of its gross domestic product, or the total amount of goods and services that the country produces each year, to set aside enough private farmland to conserve the Atlantic Forest -- one of the world's most diverse habitats.

Is MSG bad for you? Debunking a long-running food myth (video)
Few ingredients come with as much baggage as monosodium glutamate. More commonly known as MSG, the compound has had a bad reputation for nearly 50 years, so we at Reactions felt it was time to clear its name. In this week's video, we debunk MSG myths and explain why the scientific consensus is that this flavor enhancer, known for its savory umami flavor, is perfectly safe for the vast majority of people. The video is available at http://youtu.be/VJw8r_YWJ9k.
Fungus deadly to AIDS patients found to grow on trees
Researchers have pinpointed the environmental source of fungal infections that have been sickening HIV/AIDS patients in Southern California for decades. It literally grows on trees.

High school students discover stars at SMU research program
Two Dallas high school students discovered five stars as members of a Southern Methodist University summer physics research program, QuarkNet, which enabled them to analyze data gleaned from a high-powered telescope in Los Alamos, N.M. Their discoveries have been accepted into the American Association of Variable Star Observers International Variable Star Index. QuarkNet is a physics teacher development program funded by the National Science Foundation and the US Department of Energy.
