The device can chill nerves as small as a few millimeters across, but more testing and modifications are necessary before it could relieve pain in humans.

In mice, a kind of immune memory appears to protect the cells against future harm, a finding that could provide insight into treatments for irritable bowel syndrome and other inflammatory digestive conditions.

Research in mice suggests that moderating nerve activity with drugs or electrical pulses could modify tissue immune responses, curtailing the chronic pain often associated with inflammatory conditions.

Neuroscientist Rita Levi-Montalcini began her Nobel Prize–winning work in a makeshift laboratory in Italy during the Second World War.

A tiny implanted optofluidic device enables researchers to control mouse nerves without touching the animals.

An implantable wireless device with microfluidic and optical components allows manipulation of individual nerve fibers in mice’s extremities.

At $2 million for a single dose, Novartis’s Zolgensma is the most expensive medicine to date, but still less expensive over a lifetime than another approved drug for the rare genetic disease.

A bright blue stain highlights the sensory nerves of a developing mouse embryo.

The device could one day help enable prosthetics deliver richer touch information to users.

When peripheral nerves are severed, Schwann cells at the injury site begin to proliferate and exhibit stem cell-like gene expression patterns.

Low-intensity activation of the vagus nerve appears to have increased a patient’s awareness of his surroundings after 15 years without communication.

Zebrafish have a remarkable ability to heal their damaged nerve fibers following a spinal injury.

Rorqual whales’ mouths can stretch to more than double their length without causing damage, thanks to two layers of neuronal coiling. 

Researchers are using the tissue, synthesized with human pluripotent stem cells and implanted into mice, to study a rare form of Hirschprung’s disease.

A man whose hand and lower arm were amputated could sense shapes and stiffness and modulate the force of his grasp using a prosthetic hand that was temporarily wired to nerves in his upper arm.

Nerves growing in cancerous prostate glands appear to spur disease progression.

A maturing mouse gut nervous system (shown in orange), a mesh-like system of neurons that regulates digestion and gastrointenstial function, runs from the stomach through the intestines.

High omega-3 levels help mouse neurons heal better after injury.
