Snuggle Up to the Looming Nuclear Apocalypse with RST’s Gamma Ray-Fighting ‘Miracle Material’
11:00AM Gizmodo US Edition | If Radiation Shield Technologies’ Demron fabric pans out, maybe our dystopian, radiation-soaked future won’t be so bad after all. At the very least, we’ll be toasty–and fashionable too! RST says the fabric (available in full body suits, blankets, gloves and boots) protects against particle ionising/nuclear radiation, and shields against X-ray and low-energy Gamma emissions. The crazy thing is it does it all without any lead inserts, which next to a few inches of solid concrete are currently most effective defence against radiation poisoning. Instead, the material uses a proprietary nanotechnology to block a host of biological, chemical and radioactive sources. The material is damn heavy too; a 90 x 75cm blanket weighs approximately 27kg.

Lead Being Outlawed Means Your Gadgets are at Risk
8:10AM Haroon Malik | Small splinters that randomly occur in tin solder, which lace the insides of gadgets, usually result in circuits shorting out.

Conservative estimates of the cost of such splinters, or whiskers as they are named, have totaled nearly $10 billion since 1940. Preventing whiskers is a major concern to the electronics industry. The most prominent defence measure known is to use lead during the production process. Companies, excluding rogue Chinese toy manufacturers, are all being forced to slowly eliminate the use of lead in their products. More »
