3D-printed corneas could save millions’ vision

British scientists have 3D printed the first human corneas, yielding a potential fix to the worldwide shortage of corneas for implantation. The Newcastle University researchers created a bio-ink using stem cells from a healthy donor cornea mixed with alginate and collagen. They used a simple, low-cost 3D bio-printer to extrude the bio-ink in concentric circles to form the shape

This new bionic hand reacts automatically: Here’s how

British researchers are trying out a new bionic hand that they’ve developed that allows the wearer to reach out and grasp objects automatically – without the user consciously thinking – mimicking how people fluidly react to with the world around them. The key to allowing the hand to do this was a camera. The biomedical engineers at Newcastle

New hope for recovery of hand movement for stroke patients

Stroke patients are starting a trial of a new electronic device to recover movement and control of their hand. Neuroscientists at Newcastle University have developed the device, the size of a mobile phone, which delivers a series of small electrical shocks followed by an audible click to strengthen brain and spinal connections. The experts believe
