Silky material uses magnetic particles to regrow bone

It was just a couple of months ago that we heard about an implantable material that electrically stimulates bone cells, causing them to reproduce. Now, scientists have created a similar substance that utilizes magnetism.

Graphene-enhanced material may be bound for the brain

There are a variety of situations that may call for the implantation of electrodes in the brain, ranging from the treatment of neurological conditions to restoring the function of paralyzed limbs. A newly-developed hydrogel could someday replace such electrodes, allowing for better functionality.
