Brain-computer interfaces without the mess

It sounds like science fiction: controlling electronic devices with brain waves. But researchers have developed a new type of electroencephalogram (EEG) electrode that can do just that, without the sticky gel required for conventional electrodes. Even better, the devices work through a full head of hair. The researchers report the flexible electrodes, which could someday

How can you reliably spot a fake smile? Ask a computer

Real and fake smiles can be tricky to tell apart, but researchers at the University of Bradford have now developed computer software that can spot false facial expressions. By analysing the movement of the smile across a person’s face, the software can determine whether or not the expression is genuine. The most significant movements detected
