...their favorite foods and asked them to rank each on a 1-to-10 scale. The researchers then selected one food for each subject, the only requirement being that it scored 7 or above in desirability. When the 17 hours were up, the volunteers were injected with a nuclear tracer, placed in a brain-imaging PET scanner and presented with a food they craved. Actually, they were more than merely presented with...

...tried both. The TYR Tracer Rise, a $450, three-quarter-length body suit, has a large silver panel on the front with two thin stripes running from the inside of the back down the sides of the legs. These panels are made with a polyurethane coating, designed to eliminate drag. TYR spent more than three years working on the suit. The focus of its research, according to Matt Zimmer, promotions director, was the lightweight, water-repellent fabric and muscle contour compression. The idea behind the compression is two-fold: first of all it provides a barrier between water and skin...

Speedo has clearly won the Battle of Beijing. After Athens, Speedo brought an army of biophysicists, kinesiologists, and engineers to bear on overhauling the last generation of its Fastskin racing suit, the FS Pro. So the LZR Racer has a few more bells and whistles than the Tracer Rise. For one thing, it looks a lot cooler. The long grey panels - you feel like an astronaut crossed with a figure skater - are products of multiple levels of technological innovation. Speedo used a NASA lab to measure more than 90 different fabrics in a wind tunnel to find the one with...

...down the flashlight, took hold of his mounted M-240 machine gun and commenced the warning shots. He says he fired first into the grassy area on the other side of the road, straight across the driver's field of vision, each bullet followed by a bright red tracer round so that they could be heard and also seen in the dark. When the car did not slow down, Lozano says he fired at the ground in front of it, then into the tires, then the engine block until the vehicle came to a halt ten meters away from where...
