New nanosensor sniffs bombs, one molecule at a time (Wired UK)
Imagine a piece of metal 30,000 times thinner than one of the hairs on your head. Mixed with a little protein from bee venom, that microscopic filament becomes the most powerful explosives-detection system in history, able to detect a single molecule of dangerous chemicals.
Now imagine having that in an airport. No need for taking a pornographic photograph or having your genitals massaged by the Transportation Security Agency. And a nanotechnology specialist may have hastened that happy day for homeland security.
Why ‘green’ doesn’t have to mean expensive (Wired UK)
“Greener” products don’t have to be more expensive for consumers, according to industrial designer Yves Béhar.
At a meeting this week with Wired.co.uk, he explained that there is a big misconception that it costs more to create products with a lower carbon footprint. He says: “We have been told that doing things in a green way will cost more. This doesn’t work. People don’t want to pay more for something just because it’s green.”
