The next time you roll up your sleeve for a painful hypodermic jab, take heart: Researchers at the Georgia Institute of Technology may soon deliver an ouchless alternative, called microneedles. These near-invisible pokers, made from silicon, metal, glass or biodegradable polymers, are as much as 500 times smaller than an ordinary hypodermic -- too minute to irritate nerve endings, says Mark Prausnitz, lead investigator for Georgia Tech's microneedle research program.
H2.0 assumes you are a professional driver on a legal track or safe private road.

Never mind the straight-arm posture you see in action movies. With your shoulders against the seatback, you should be able to rest your wrists atop the wheel. Hold it firmly but with your fingers, not in a baseball-bat death grip.
IT'S THE TIRES, STUPID.
They should be ZR-rated, of course (capable of a sustained 150 mph), but they should also be dynamically balanced for high speeds,
in flawless condition, and inflated to halfway between the carmaker's comfort recommendation and the tire maker's max inflation pressure (on the sidewall).

Jeffrey Stephenson's polished wood and chrome humidor sits gracefully in his living room, holding four dozen cigars, all dried to a crisp. That's because under the smokes lie a DSL modem; firewall and cache with 20GB of disk space; and a wireless hub streaming bits to and from every computer in his house.
In the hunt for toxins, spy insects go where humans can't.

That, at least, is the vision of Jeff Brinker, a materials scientist at Sandia National Laboratories in Albuquerque. Brinker and his team have devised a way to transform the loathed insects into stealthy environmental sentinels to detect chemical or biological agents.

NAME Bob Dancer
JOB Professional video poker player and teacher. Dancer originally moved to Las Vegas to become a blackjack ace, but changed his name—Dancer is a pseudonym based on his other life passion—and his game when wary casino owners caught on to his card counting. Switching to video poker turned out to be a lucrative career move—during one six-month stretch in 2001, for example, he netted a cool million. (His greatest loss, $90,000, occurred during the same period.)
