Nerves
-
Artificial devices usually don’t communicate well with nature. Now, researchers have created artificial organic neurons and synapses that can integrate with natural biological systems, and demonstrated this by making a Venus flytrap close on demand.
-
After an injury, nerves struggle to regrow completely, leaving patients with reduced mobility and sensation. In tests on rats, researchers have now demonstrated a way to improve nerve repair using proteins from the support network around cells.
-
A new type of artificial scaffold encourages regenerating neurons to grow towards one another and bridge busted connections more efficiently, offering new hope for healing damaged spinal cords and restoring communication links between the brain and body.

When someone injures a nerve in a body part such as a finger, it's not uncommon for that part to end up with a permanently decreased sense of touch. A self-powered implantable sensor, however, could one day restore sensitivity to such injured areas.
-
In a new study, occipital nerve stimulation has been found to reduce the frequency and severity of headaches in patients suffering chronic cluster headaches, and the results suggest low doses of electrical stimulation are as effective as high doses.
-
New research led by scientists from UT Southwestern suggests a novel combination of three old antibiotics may be repurposed into an alternative to opiates for a particular kind of nerve pain.

One common symptom of multiple sclerosis (MS) is vision impairment, and it can progress to blindness in some cases. Now, researchers at the University of California, Riverside report a drug that was able to reverse that vision loss in mice.
-
German scientists have restored the ability to walk in mice that had been paralyzed by a complete spinal cord injury. The team created a “designer” signaling protein and injected it into the animals’ brains, stimulating nerve cells to regenerate.
-
Researchers have discovered a new kind of immune cell with the ability to not only prevent the progressive neurological degeneration associated with diseases such as multiple sclerosis and ALS, but which may even regenerate and repair damaged cells.
-
Scientists have identified a chemical compound that may unlock new treatments for multiple sclerosis. In tests on cell cultures and rats, the team found that anacardic acid from cashew shells seemed to repair nerve damage and other symptoms of MS.
-
Goosebumps are a weird quirk of our bodies that science doesn’t fully understand. Now, researchers at Harvard have uncovered a biological reason for the reaction: it’s our bodies’ way of stimulating stem cells to drive new hair growth.
-
As some readers may already know, in-ear stimulation of the vagus nerve can help relieve pain in other parts of the body. Thanks to new research by Austrian scientists, such treatments could soon be more effective than ever.
