A breathalyzer for cocaine?

Scientists have built a rudimentary handheld drug detector that can sense cocaine through masking agents in blood, dirt and food, according to a report from LiveScience.

Researchers at the University of California, Santa Barbara, developed the portable device with an internal engine lined with a DNA molecule called an aptamer, which stiffens and folds when it enounters cocaine. When an electronic signal is passed through the fast-acting device, the aptamers will bind to the cocaine and allow electrons to pass through more readily, according to the report.

Typically, cocaine tests take hours in a lab. Tests that police use in the field can also be scotched by substances drug dealers mix with cocaine. The prototype of the new device has so far detected cocaine through a variety of mixers, such as coffee and mustard powder; and its ability to pick up traces of cocaine in blood or salvia make it feasible that it could one day be used as a cocaine-alyzer (similar to a breathalyzer test for alcohol), according to the report.

Details about Apple's 'spaceship' campus from the drone pilot who flies over it

MyithZ has one of the most popular aerial photography channels on YouTube. With the exception of revealing his identity, he is an open book as he shares with CNET's Brian Tong the drone hardware he uses to capture flyover shots of the construction of Apple's new campus, which looks remarkably like an alien craft.
