...University of Southern California's Fisher Gallery in Los Angeles, experts are creating special 3-D images of the museum's Chinese teapot collection via laser photography. The pots can then be "touched" by anyone, anywhere - as long as they have some fancy (and still fairly bulky) equipment like the Phantom, produced by SensAble Technologies Inc. of Woburn, Massachusetts. A stylus attached to the desktop device transmits force feedback to the user's fingertips. Following a model on your computer screen, you run the stylus over the "body" of the virtual teapot in the air and feel its curved, slick...
...Unsurprisingly, it's complicated. But the closely related techniques used by the two teams both involve canisters of chilled gas - Walsworth's team used rubidium, treated with a pair of laser beams that rendered it transparent - into which the light can enter without being absorbed. Instead, the first beam leaves its mark on the gas particles while the second beam is slowly turned down by the physicists. As that happens, the first beam grinds to a halt - and goes dark...
...boom is fueled in large part by new, less costly "quick fix" techniques that don't involve major surgery: botox injections that temporarily eradicate facial lines, derma-fills that smooth out wrinkles and scars and build up lips and cheeks, and laser beams that zap away lines. Liposuction, the process of vacuuming fat from the body, is gaining in popularity thanks to advances in keyhole surgery and other less intrusive techniques...

...help illustrate forensic science in action, the ExperiMentors volunteers decided to script a kidnapping that the students would then spend the day unraveling. Dolan was followed on stage by a guest lecturer who mysteriously disappeared after volunteers lit several hydrogen balloons on fire. The explosion, a laser light show and Mission Impossible theme music indicated to the crowd that the guest lecturer was the victim of a kidnapping and the students were now charged with her recovery...
