Drug seeking becomes compulsive, in large part as a result of the effects of prolonged drug use on brain functioning and, thus, on behavior. For many people, drug addiction becomes chronic, with relapses possible even after long periods of abstinence.

Never get so addicted coz nothing last for ever.
Drug addiction is a complex brain disease. It is characterized by compulsive, at times uncontrollable, drug craving, seeking, and use that persist even in the face of extremely negative consequences.

Robet Suit
A consortium of 30 Japanese companies are planning on working together (yeah, like that ever happens) to produce a robot exoskeleton that can be worn by the infirm, elderly or handicapped people. A prototype of HAL-3 (Hybrid Assistive Legs) has been developed by Yoshiyuki Sankai, professor and engineer at Tsukuba University. Developers hope that by the time these devices come to market, they will be "thin enough to be worn like underwear and will allow users to run and move...freely."
Everlasting Flight, Here We Come...
New Scientist: For the first time a solar-powered plane has flown through two consecutive nights, UK defence research company QinetiQ claims. In a secretive weekend mission, their craft Zephyr took off from a US military base in New Mexico and landed 54 hours later. The solar craft seems to have taken the next hop towards everlasting flight...
The Origins of the Rocket Belt
Speaking of rocket belts, I just put up a piece I did for Discovery Online in 1997, for their Alt.Tech column, which I contributed to for awhile. Called "Blow Your Socks Off," it tells the story of the development of the original Bell Rocket Belt. There are even a couple of nifty short movies, with that kind of "Gee Whiz, Jimmy" ''60s space age narrative that we all know and love.
Flying Car
After seeing the train wreck (or more accurately, robot wreck) that was the first DARPA Grand Challenge, with out-of-control robot rovers ditching themselves in the desert, is the idea of a similarly-styled flying car challenge a good one? NASA thinks so. According to a piece on Luxist, the space agency has announced a Personal Air Vehicle Challenge. While the grand prize for the DARPA Challenge is now set at US$2 million, NASA's only ponying up 250 Gs. Maybe that's 'cause they'll need the rest of the cash for hardened bunker construction. "INCOMING!"
