...going to bust pimps by arresting prostitutes," says Dominique Achispon, assistant general secretary of the National Union of Police Officers. "It's very hard for a prostitute to say who she works for. Most girls who inform on pimps are either found dead or vanish without a trace." Boucher claims the new law will actually make matters worse, as pimps cover their losses by putting more girls to work. The situation is complicated by prostitution's awkward legal status in France. Before World War II, the country had some 1,500 licensed brothels. Since they were abolished...
Schizophrenia is where much of the pioneering work in this field has occurred, and the images on the following pages trace the remarkable journey that scientists are taking as they search for the roots of this disorder and perhaps someday a cure...
...putting bags through the huge explosive-detection-system (EDS) machines that travelers have seen at U.S. airports for years. But for the first time on a wide scale, checked bags will also be opened and hand-searched by a TSA employee or examined with the help of an explosive-trace-detection device, which often requires opening the bag as well. In addition, the TSA is using bomb-sniffing dogs and a system called bag matching, which actually does nothing to detect explosives but merely makes sure that if a passenger misses a flight, his or her bag will be held...

...contamination on Earth rather than true evidence of life on Mars. What distinguishes the Beagle's mission is that it will effectively carry out tests in situ on organic matter. If all goes well, the Beagle's robotic paw will scratch and claw at nearby rocks, sniffing for the trace gases, organic compounds and complex chemicals. Soil samples will be dug out using the mole, a robot that can tunnel deep beneath the surface. Any life on Mars, past or present, would leave its chemical imprint - or 'fossil' - inside the rock. Pillinger's team has developed a miniaturized gas analysis...
