Transplant

Replacing damaged spinal cord with healthy donor tissue sounds like a straightforward solution to paralysis. Getting those tissues to exchange meaningful messages is another matter entirely. A team claims to have attempted this extraordinary feat in Russia

A groundbreaking experiment has dramatically advanced the field of lab-grown neural models, with researchers fusing a human cortical organoid with another animal's nervous system. Now, scientists are weighing up the ethics versus the potential.

As hydrogen-powered vehicles continue to evolve, their use will become as niche as that of some current land-, sea-, and air-transportation methods, such as a new agreement that will see helicopters powered by the green fuel used for organ transport.

Prellis Biologics has brought the science fiction dream of printing human organs for transplant a step forward by developing a fast, high-resolution 3D printing technique that can produce living tissue that includes viable blood-carrying capillaries.
