...Designed for extreme cold, the North Face MET5 jacket can keep you warm all by itself, thanks to a network of microscopic, waterproof heating elements woven into the fabric. Working a control unit stashed near the chest, you can dial the heat up to 114[degrees]F. Small lithium-ion batteries keep the juice flowing for up to five hours...

...depends on how the radiation is delivered. Manufacturers of food and medical irradiation equipment say tests have shown that either of two technologies--ion-beam or gamma-ray--can render the spores inoperative by crippling their...
...USPS decided to go with ion-beam irradiators...
According to their promoters, ion-beam (also known as electron-beam) devices are fairly safe and relatively fast, killing anthrax spores in a matter of minutes. Independent experts question whether they can do the job that quickly. The gamma rays in the competing systems penetrate more deeply into packages and piles of envelopes, but they can take hours to destroy any spores that may be in them. Also, each gamma-ray machine uses a small quantity of radioactive cobalt 60 as its energy source, posing safety and disposal risks that could make an already nervous public even more...
