crazy century. Didn't Nostradamus predict that? The ongoing Military Health Research Forum is discussing the use of an injectable hydrogel for the treatment of traumatic brain injury, which -- unlike our ability to do push-ups -- is no joke. The fertilizer part comes from the gel's ability to stimulate the growth of neural stem cells within the brain, which are then capable of repairing damaged nerves and preventing the spread of harm to other cells. "Brain tissue regeneration" might not be the wisest name for it, but tests on rats have shown sustained functional recovery, and we understand that with enough Igors on the job, this could be put into use within the next three years.
