Restoration of vision in blind people through a brain implant is on the verge of becoming reality. Recent discoveries at the Netherlands Institute for Neuroscience (NIN) show that newly developed high-resolution implants in the visual cortex make it possible to recognize artificially induced shapes and percepts. The findings were published in Science on 3 December.

Surgeons will soon have a powerful new tool for planning and practice with the creation of the first full-sized 3D bioprinted model of the human heart.

As time goes by, the tips of your chromosomes—called telomeres—become shorter. This process has long been viewed as an unwanted side-effect of aging, but a recent study shows it is in fact good for you.
