...impressive array of equipment. Among the instruments are a drill capable of digging 5 ft. below the surface, 12 ovens that can heat samples to some 1,600ºF to generate carbon dioxide and a mass spectrometer to identify carbon isotopes, along with other elements. The lander can also measure ultraviolet radiation, temperature and atmospheric pressure, all variables that play a key role in biology. "If there is one mission capable of detecting past and present life, it will be ours," says planetary scientist Colin Pillinger, a professor at Britain's Open University and the man who dreamed up the project...
...people with really sensitive skin, sunscreen sometimes isn't enough. More manufacturers are offering clothing--some fashionable, some burqaesque--specially designed to protect skin from harmful ultraviolet (UV) rays. Solar Eclipse sells a "driving sleeve" for arms that hang out of car windows. Sun Precautions has a nose-to-neck ventilated mask (above). And Coolibar offers a kid's cap with a protective neck drape...
...impressive array of equipment. Among the instruments are a drill capable of digging 1.5 m below the surface, 12 ovens that can heat samples to some 870?C to generate carbon dioxide and a mass spectrometer to identify carbon isotopes, along with other elements. The lander can also measure ultraviolet radiation, temperature and atmospheric pressure, all variables that play a key role in biology.

...nanotech summit at his country residence, Highgrove House in Gloucestershire. But while Prince Charles ponders doomsday scenarios, millions of people already use the products of nanotech research every day without even knowing it. Consumers of Sunsorb brand sunscreen have nanotech to thank for that product's invisible protection against ultraviolet rays. And it's nanotech that makes Pilkington's Activ windows shed dirt in the rain. If these mundane marvels are not impressive enough, researchers will soon bring us toothpaste that coats, protects and repairs damaged enamel, as well as self-cleaning shoes that never need polishing. Nanotech may also...
...hormones--pose the same threat as estrogen alone. "If this concerns you, talk to your physician about it," says Dr. Christopher Portier, associate director of the NTP. Among the 14 other substances to make the NTP list: wood dust, common in sawmills and furniture-or cabinetmaking workshops; broad-spectrum ultraviolet radiation, from the sun or tanning beds; and IQ, a compound found in cigarette smoke that is also formed when foods like meats and eggs are cooked in high heat.
