Devices using terahertz radiation could lead to applications in security screening, chemical sensing and more

Terahertz radiation, or T-rays, can see through clothing, paper, cardboard and numerous other materials, so scientists have been touting their potential for years. A T-ray-based imager could spot concealed weapons hidden under a person's clothes or even identify tumors without inducing any bad side effects.
MIT scientists say they've found a new way to silence disease-causing genes in specific tissues using RNA interference

For years scientists have been touting a disease-fighting technique called RNA interference. The idea behind it is pretty simple: By piggybacking on the body's own system for silencing genes, researchers think they could stop troublesome proteins from being produced, and, as a result, halt the damage those proteins cause. The trick, though, is that scientists have had a hard time figuring out how to make RNAi, as it's known, work on specific tissues.
Nanotechnology in food could be the cure-all we've been searching for. But is it safe?

Steve Boggan has written an excellent article today in the Guardian on nanotechnology and its implications in the industrial food market. The first five paragraphs are as good a primer on nanotech as youre likely to find—send this one to your mom if she has any questions. The rest of the article is a closer look at its future in our food supply, particularly in light of consumers recent widespread distaste for genetically modified goods. The bottom line: the industry is outwardly hopeful about the technologys promise, but inwardly cautious about the public response. Oh, and we have no idea what itll do to us when we eat it.
It's not bling, but this nano-ring may be the key to a quantum computer

Granted, it will be far too small for her to show off to her friends, but if your potential fiancée has a love of science, she just might accept this bauble over something flashier. Its the worlds smallest diamond ring, created by a group of Australian physicists. The ring measures just 5 microns wide and 300 nanometers thick. And no, its not really for advertising your engagement. The ring is actually part of a device used to produce and detect single photons.
Chemists build the worldâ€™s smallest auto dealership, molecule by molecule. No toy models, these cars actually drive

The most prolific car manufacturer on the planet resides in a Rice University laboratory in Houston, where chemist James Tour and his colleagues have built one trillion trillion nanoscopic cars. The tiny four-wheeled vehicles are only four billionths of a meter wide-25,000 of them parked side by side would be about as thick as a piece of paper. Not just another nano-gimmick, Tour´s cars could one day carve tiny channels in silicon, creating more-powerful computer chips.
