A biodegradable scaffold repairs nerve damage in mice
A fully biodegradable nerve scaffold not only helps regenerate damaged nerves, but negates the need for retrieval procedures.
Creating realistic “squishy” brain tissue in the lab
Growing brain tissue requires capturing the realistic “squishiness” and cohesion between cells, but how each cell type contributes has been a mystery.
Harnessing piezoelectric materials to regrow neurons
When activated by mechanical stress, a piezoelectric material efficiently stimulates the differentiation of stem cells into new neurons.

An engineered skin with a new secret ingredient helps avoid harmful inflammation while speeding up the wound healing process.
Treating inflammatory diseases with oxygen-scavenging catalysts
Catalysts that mimic antioxidase enzymes show promise in treating inflammatory diseases, such as gum disease, lupus, or cancer.
An implantable device reconnects nerves
An implantable hybrid device combines the benefits of two therapeutic approaches to help repair nerve damage.
Electrical stimulation restores patients’ ability to walk after spinal cord injury
In patients with spinal cord injury, an implanted neurotransmitter restored their ability to walk, but underlying reasons were unexpected.
New artificial blood vessel integrates into the body
A new class of artificial blood vessel better mimics its natural counterparts and gets incorporated as a living vessel in the body after implantation.
