Scientists discover mechanism that could regrow damaged nerves


The discovery could lead to developing a drug that can trigger regrowth of damaged nerves.

Spinal cord injuries are currently irreparable. Most people who suffer from such an injury never fully recover, and many end up with partial or even full paralysis. Although we’ve made great strides in understanding how spinal injuries damage nerves and how we might fix the spinal cord in the future, and even how those patients can cope in the meantime, we still don’t know how to repair the nerves themselves when such an injury occurs. However, scientists at Imperial College London have recently discovered a mechanism that allows them to repair, and even regenerate, nerves in the central nervous system after a spinal cord injury.

Neuroplasticity: How our brain rewires and adapts (Infographic)


Neuroplasticity helps the brain to reorganize itself.

The human brain is a marvelous thing. It helps us learn, helps us adapt. A core part of these abilities is thanks to neuroplasticity, which allows our human brain to reorganize itself as necessary — even after traumatic brain injuries (TBIs).

Injectable foam stops internal bleeding on the battlefield

The polyurethane foam begins as two liquids stored separately and injected together into the abdominal cavity.

Despite the best efforts of military first responders to stabilize abdominal wounds sustained on the battlefield, they have few options when it comes to stopping internal bleeding caused by gunshots or explosive fragments.  DARPA is studying a new type of injectable foam that molds to organs and slows hemorrhaging. This could provide field medics with a way to buy more time for soldiers en route to medical treatment facilities.
