A number of sensors have been developed to detect excessive alcohol consumption and prevent impaired drivers from starting their vehicles. The application has primarily been incorporated as a punitive step for repeat offenders. However, when a carmaker proposes a concept, the possibility of OEM use gets a step closer to reality — a step which could prevent or reduce deaths and accidents from drunk driving. Saab's Alcokey concept combines an alcohol sensor with engine immobilizer technology. A key fob with an integrated mouthpiece provides a sample of the alcohol content in the driver's breath to a small semiconductor sensor. An excessive level of alcohol prevents the engine from starting similar to the immobilizer in existing anti-theft systems.

Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
