...scientists can flesh out the new findings during future earthquakes - a two-year study at the same seismically active location begins this September - it could form the basis of a vastly improved early-warning system for quakes. Current earthquake-warning systems give just a few seconds' notice because they detect only P-waves, the fast-moving seismic waves that precede the more destructive waves released during a quake. Upgrading to a seismic stress meter, however, is still a long way off. "To use this for earthquake prediction, you need to know the precursor waves have a physical basis [that...
...have been able to set up sophisticated communications systems, financial networks and training facilities. Al-Qaeda "has hundreds of training camps" scattered throughout the FATA, says a Western official in Pakistan with access to intelligence reports. "Most are less than an acre in size, so they are difficult to detect...
Computed tomography (CT or CAT) scans help doctors detect everything from cancer to kidney stones. But some physicians are raising concerns about the safety of such procedures - most notably, an increase in cancer risk. A CT scan packs a mega-dose of radiation - as much as 500 times that of a conventional X-ray. If your doctor orders a CT scan for you or your child, should you think twice...
...Thanks to the evocatively named High-Accuracy Radial-Velocity Planet Searcher (HARPS), a telescope mounted atop La Scilla Mountain in Chile, Mayor and his team were able to detect a litter of new planets, some as small as four times the mass of Earth - tiny by exoplanet standards. One star, just 42 light-years away, is home to a trio of such worlds - which Mayor is now calling "super-Earths." The largest of the three is just 9.5 times as big as Earth, the smallest just 4.2 times. It was not only the modest size of all the new worlds...
...long as the child eats properly and stays active enough to keep calorie input in line with what's burned off. Kumar says the key to reversing liver abnormalities--not to mention all the additional burdens excess fat places on the heart, bones and other organs--is to detect signs of weight gain in kids early. "We don't want to get to the point where children are so overweight, they have trouble moving," she says. "If that happens, we've lost the battle." As any parent of an overweight child knows, in the war on obesity, every battle counts...
