Quantum Internet Has Big Security Hole

Staff at a government laboratory have revealed they’ve been using a quantum internet since late 2010. But it’s an extremely simple model and might not scale well. The idea of a quantum internet scales from quantum computing, which used the magnetic orientation of atomic particles as a way to encode 0s and 1s. Simply put, […]

Electric Fly Takes Flight

The world’s smallest flying robot has made its maiden voyage. The tiny device uses electrically-powered movements that mirror the way a fly propels itself. The robot, dubbed RoboBee, is the work of staff at Harvard University. It’s barely bigger than a coin with a three-centimeter wingspan and weighs less than 0.1g. The carbon fiber robot […]

Batteries Could Get 10 Times Smaller

University of Illinois researchers say they’ve found a way to make batteries far smaller and much quicker to recharge. The technique works in the same way as traditional batteries, but makes much more efficient use of space. As the BBC explains with admirable clarity, batteries work by electrons flowing from one type of electrode (an […]

LED Tech Comes to Office Strip Lighting

Philips says its found a way to make LED lighting that’s twice as efficient as existing fluorescent bulbs. It would mean bringing the type of energy savings found in many homes to offices and factories. Although mention of energy-saving bulbs usually brings to mind domestic light fittings, Philips says around half of all energy used […]
