Improved retinal transplant technique ready for clinical trials

Researchers have used a genetic modification to improve human-derived retina transplants grown in the lab. After transplant into damaged mouse retinas, timed removal of certain cells from the grafts allowed better connections to host retinas, which resulted in more responsiveness to light in the damaged eyes.

Bone growth inspired 'microrobots that can create their own bone

Inspired by the growth of bones in the skeleton, researchers have developed a combination of materials that can morph into various shapes before hardening. The material is initially soft, but later hardens through a bone development process that uses the same materials found in the skeleton.
