By Lisa Maria Garza and Jim Forsyth DALLAS (Reuters) - Storms bringing as much as 7 inches (17.8 cm) of rain drenched North Texas overnight into Friday, prompting hundreds of calls for emergency assistance and adding to the woes of the state where at least 20 people have been killed in severe weather this week. The National Weather Service issued a flash flood watch for an area from Central Texas into Kansas, with the additional rainfall swelling Texas rivers already at dangerously high levels. The 7 inches in North Texas from Thursday morning into Friday comes after storms dumped as much as 11 inches (28 cm) overnight on Monday in the Houston area, where more than 4,000 structures were damaged in floods.
Live anthrax has been found in a 2008 sample sent to Australia from the same U.S. Army facility identified this week for more recent, mistaken shipments to nine U.S. states and an air base in South Korea, a U.S. defense official said on Friday. The U.S. official, who spoke on condition of anonymity, did not know what kind of facility in Australia received the sample, which, like the others, was meant to have been inactive. The discovery was made during the investigation into the U.S. Army's Dugway Proving Ground in Utah that was cited for the other mistaken shipments.
By Barbara Goldberg NEW YORK (Reuters) - A U.S. Navy SEAL hopeful and his friend, an off-duty lifeguard, were barreling through underwater drills in a pool just 3.5 feet (1 meter) deep. This summer, nearly four years after those deaths in a Staten Island pool raised alarms about a little known hazard called shallow-water blackout or hypoxic blackout, New York City is putting up warning signs at all public pools prohibiting prolonged breath holding. It is part of a movement to raise awareness of the peril that has killed accomplished swimmers and to stop it by banning lengthy breath holding in the nation's estimated 300,000 public pools.
