Carbon-14 fallout from above-ground nuclear weapons testing in the 1950s is embedded in tooth enamel, allowing scientists to estimate age to within 1.6 years, Jonas Frisen of the Karolinska Institute in Stockholm reported this week in the journal Nature. Tooth enamel contains 0.4% carbon. Concentrations in teeth thus reflect the amount in the atmosphere when the enamel was formed. It does not work for individuals born before 1943 because their teeth formed before nuclear tests began.

Syria test-fired three Scud missiles last week, including one that broke up over Turkey, senior Israeli security officials said. The officials said the missiles, using North Korean technology and designed to carry chemical warheads, were fired May 27. In New York, Israeli Foreign Minister Silvan Shalom said the Syrian tests were "very dangerous." There was no comment from Damascus. The New York Times first reported Israel's allegations in Friday editions.

Northrop Grumman Corp., the third-largest U.S. defense contractor, said Tuesday that it planned to finish within 18 months a prototype of a battlefield laser weapon capable of shooting down mortars and rockets, Chief Executive Ronald D. Sugar said. "Laser weapons aren't Buck Rogers weapons anymore," Sugar said in a speech at the National Press Club in Washington. "They're becoming a reality. Almost every day our troops face mortar and rocket fire from insurgents.

The Russian military successfully test-fired a mobile version of its top-of-the line Topol-M intercontinental ballistic missile. The missile was fired from a mobile launcher at the Plesetsk launch pad in the northern region of Arkhangelsk and hit a designated target on a testing range on the far eastern Kamchatka peninsula, military officials said. The launch is expected to be the last of four test-firings of the Topol-M's mobile version before its deployment, which is expected next year.

The Army is planning to expand the nation's leading biological and chemical defense testing site in Utah's remote western desert to make it a training ground for counterterrorism operations. The seven-year plan for the Dugway Proving Ground includes building a mock city for urban chemical and biological attack exercises and refitting existing facilities for use in counterterrorism training. A permanent annex would be built for biological defense trials.

Iran has added a "strategic missile" to its arsenal after a successful test, and the country is ready to confront any external threat, the nation's defense minister told state-run radio Saturday. The radio report did not say whether the test involved the previously announced new version of the Shahab-3 rocket -- capable of reaching Israel and U.S. forces stationed in the Middle East -- or a different missile.

Iran on Saturday dismissed allegations that it was providing test sites for North Korean long-range missiles designed to deliver nuclear warheads, its official Islamic Republic News Agency reported. A Bush administration official said last week that North Korea was getting around a self-imposed missile test ban by sharing technology information with Iran, which is allegedly carrying out missile tests on Pyongyang's behalf.

India successfully fired a nuclear-capable missile off the coast of the eastern state of Orissa in what a Defense Ministry spokesman called "a routine test." The Agni 1 missile has an estimated range of 750 miles. India is developing an array of missiles as part of its nuclear defense strategy against neighbors China and Pakistan. India staged nuclear tests and declared itself a nuclear power in 1998, prompting longtime rival Pakistan to respond with similar tests.

The State Department's former senior expert on North Korea said Tuesday that the Bush administration's refusal to engage directly with the country made it almost impossible to stop Pyongyang from going ahead with its plans to build, test and deploy nuclear weapons. Six- nation talks are a good step, but not enough, said Jack Pritchard, who was the department's special envoy for negotiations with North Korea until he resigned last month.
