...Plenty of scams, though, are more elaborate and harder to detect. During a search of Richard Pierre's house, police seized thousands of envelopes with a fake company's logo...
...warheads across the country. In 1983, Ronald Reagan called for a nonnuclear approach, inevitably nicknamed Star Wars, that would destroy missiles from space using yet-to-be-developed particle beams and lasers. It was followed in 1988 by a plan for thousands of small satellites, dubbed Brilliant Pebbles, to detect and destroy enemy missiles by ramming into them. The program received nearly $100 billion in funding before the Soviet Union collapsed, taking the rationale for such a project with...
...taken so long to do a study of this sort? For one thing, you need an enormous sample size - at an enormous cost - to find significant numbers of people with autism. Second, it's more difficult to detect autism in adults than in children. Children often have glaring symptoms, like delays in learning to speak, extreme social withdrawal and terrible tantrums. Less is known about how autism looks in adults. "To diagnose autism, you need to have good information on people's behavior," says Brugha. "It's much more straightforward to get that with children because you've got parents...
...have suffered severe burns while trying to mix the explosive in makeshift laboratories. For terrorist groups, however, the risks of TATP are outweighed by the advantages. The white, sugarlike powder is lightweight and nearly odorless (the better to evade bomb-sniffing dogs) and contains no nitrogen (foiling scanners that detect nitrogenous bombs). Its basic ingredients - acetone, hydrogen peroxide and acid - are readily available in beauty supplies and home-improvement products. Al-Qaeda operatives have been using the stuff for years...
During its survey, the Langseth had five approved observers on board to watch for marine mammals for 30 minutes before any airgun use. The operation shut down if any were spotted. They used passive acoustic monitoring (PAM) to detect vocalizing marine mammals in times of poor visual clarity. But Rose says that animals are often silent, and some "have high frequency vocalizations, which can only be detected when a PAM system is quite close." In other words, it would be too late to avoid airgun harm. Lee-Ann Ford, president and founder of Hong Kong-based Linking Individuals for Nature...
