Now one research group is reporting a major step toward a touchy-feely prosthetic. A team of researchers from the University of Chicago and Johns Hopkins University performed a series of experiments that showed they could send electrical signals directly to the brains of rhesus macaques and that the macaques were able to interpret the signals as touches on different parts of their hands. Another series of experiments showed rhesus macaques could interpret different direct-to-brain signals as touches of varying pressure. A third explored whether direct-to-brain signals work quickly enough to be able to accurately tell macaques when a prosthetic is touching something and when it stops the touch.

The unassuming little point of light in the centre of this image is something really quite special. Just 6000 light years away, it's the oldest star ever discovered. Going by the designation of SMSS J031300.36-670839.3, this star is older than the very galaxy which we live in, and formed when the Universe itself was still young.
