As a weapon against osteoporosis, the drug's beginnings were inauspicious -- it was shelved for almost 50 years, and its main component is a mineral widely regarded as nonessential. But the compound could become a potent treatment for the bone-thinning disorder affecting millions of Americans. Called strontium ranelate, the medication is made from the mineral strontium, discovered in lead mines in Europe more than a century ago.

Two U.S. research teams have developed new materials that may pave the way for ever smaller, faster and more powerful electronics. Using ceramic crystal materials known as lanthanum aluminate and strontium titanate, one team has made tiny transistors -- the building block of computer processors -- a fraction of the size of those used on advanced silicon chips. Another team has made a film material capable of storing data from 250 DVDs onto a surface the size of a coin. Both advances were published Thursday in Science.

A taxi driver was detained after authorities in the Georgian capital, Tbilisi, found nerve gas and radioactive materials that can be used to make a "dirty bomb" in his cab, officials said. Tedo Mokeliya was detained May 31 after police discovered two containers of cesium-137 and strontium in his taxi, said Givi Mgebrishvili, chief of the Interior Ministry's main criminal investigation department.

A leak of radioactive Strontium-90 at the Energy Department's Oak Ridge National Laboratory caused unusually high levels of radioactivity in White Oak Creek for several hours Friday. Laboratory spokesman Ed Aebischer said water samples taken Friday morning showed radioactivity levels four times above the creek's normal level. But Friday afternoon samples were normal, Aebischer said, indicating the problem had corrected itself.

The radioactive beagles are long gone, their frozen carcasses hauled off to a nuclear waste dump in Washington state along with 140 tons of radioactive dog sewage. Their legacy, however, has jolted residents of this environmentally conscious college town, which declared itself a "nuclear free zone" a decade ago. After all, this is a community where the bicycle is king, recycling is a popular pastime and smoking is banned even on downtown sidewalks.

U.N. and Georgian nuclear experts finished removing two radioactive containers found in a forest. Lumberjacks discovered the containers of strontium-90 in December near Dzhvari, 135 miles northwest of Tbilisi, the capital. Experts encased the objects in protective lead receptacles and brought them out of the woods, said Soso Kukushadze, head of the radiation security department of the Environment Ministry. The woodsmen were treated for radiation-related injuries.

Tests on bottled water turned up a variety of contaminants often found in tap water, according to a study released Wednesday by an environmental advocacy group. The findings challenge the idea that bottled water is purer than tap water, the researchers said. All the brands in the study met federal health standards, but two violated a California standard, said the Washington-based Environmental Working Group.

Three lumberjacks who found containers with highly radioactive materials in a forest were hospitalized in serious condition, and hundreds of villagers living nearby have been thrown into panic, Georgian officials said Saturday. The two containers with strontium 90, believed to have been used in signal beacons during the construction of a nearby hydroelectric plant 30 years ago, were found last month near the village of Dzhvari, about 135 miles northwest of Tbilisi, the capital.
