Well, a few clever people at the University of Glasgow can, though they can’t do it very well and they may not be Scots, but why should that get in the way of a good headline?
Anyway, the point is that these clever folks at the Institute of Neuroscience & Psychology are starting to decode the various brainwave patterns associated with different activities of the brain. Specifically they can now tell, from looking at your brainwaves, whether a face you are looking at is showing particular emotions such as happiness, fear and surprise. That may not be hugely useful right now, but it is an early small step on a long and interesting road. Details here.
Of course such scientific advances are of minor interest compared to the massive breakthrough of brainwave controlled cat ears.
