Easy Rider
How do you make a bicycle that never needs lube, never leaves grease on your pants, and always delivers smooth pedaling? Simple: Ditch the chain. For its new Soho commuter bike, Trek replaced greasy metal links with a dry belt. Unlike other attempts at such bikes, the Soho is silky smooth to pedal. And it’s the first to offer multiple speeds, using an eight-gear transmission inside the rear-wheel hub.

This belt will obviously cause virtually no wear and tear on the gears... should be quieter, and from the looks of it smoother pedaling! I like it!

PopSci.com 5-Minute Project Video: Insta-cool Beer Chiller
Editor Jake Ward demonstrates how to use an old plastic container and a can of air to take a beer from lukewarm to mountain-stream cold in just a few seconds. (For another video of this project, visit sonicIntoX’s channel at Metacafe.)

Thar She Blows
When Kai Grundt announced his decision to build the ultimate snowblower from a discarded V8 engine, a friend of his just laughed. So a year later, instead of showing his buddy the finished product, Grundt showed him what it could do. He buried the man's truck under a seven-foot-tall pyramid of snow. From two houses away.

Birth Control for Animals
"Mother Goose" might soon be an anachronism. In wildlife biology, concerns about animal populations often stem from unnatural declines; in a few cases, however, that concern can be a result of too many animals, not too few, as some once-threatened species have returned with a vengeance. Now a group of researchers is fighting back with a familiar (to humans, at least) tactic: birth control.
3.6.2009 at 09:02am - Comment by AmonraThe problem with reintroducing predators into the wild is that human populations have grown to such a level that there will inevitably more encounters with wild predators and consequently fatalities to humans. From a "natural" standpoint a balance between predator and prey would be ideal however from the human geographical standpoint, no one would want their child mauled or killed by a mountain lion who sees the little one as "fair prey." Its messed up to influence nature to this level but it seems like the best way to control the populations causing problems without harming uninvolved species.
