A nonnuclear explosion expected to generate a mushroom cloud over the desert 85 miles from Las Vegas will be postponed while a federal court reviews the plan, officials said. The experiment won't be conducted earlier than June 23, said Cheri Abdelnour, a spokeswoman for the federal Defense Threat Reduction Agency. A federal lawsuit seeking to stop the blast claims that the planned 700-ton ammonium nitrate and fuel-oil bomb will kick up radioactive fallout left from nuclear weapons tests.

An environmental and antinuclear group is calling on federal officials to cancel plans to detonate 700 tons of explosives at the Nevada Test Site in an experiment designed to study ground motion and shock waves. Citizen Alert is one of several groups to oppose the test since a Defense Department official stirred controversy last week by saying the June 2 explosion would create "a mushroom cloud over Las Vegas." Federal officials have since retracted the statement.

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.

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.
