Tiny emitters near the spinal cord will release flashes of light
Damaged nerves mean that the flow of electricity coming or going to or from the brain no longer reaches its destination. This can happen during an accident, or it can be an inherited disability. Either way, the quality of life for people ...
Researchers at the University of Southern California (USC) have identified a novel mechanism in the regulation and differentiation of neural stem cells.
Researchers found that the protein receptor Ryk has a key role in the differentiation of neural stem cells, and demonstrated a signaling mechanism that regulates neuronal differentiation as stem cells ...
The adult central nervous system has limited ability to repair itself. That's why spinal cord injuries leave people permanently paralyzed. Now a study with mice finds that removing a particular signaling molecule in adult neurons restores their ability to regenerate damaged axons, the long extensions that convey signals from one neuron to another. The find potentially paves ...
Editor's Note: This story, originally printed in the September 1999 issue of Scientific American, is being posted due to a new study showing that nerve cells can be regenerated by knocking out genes that typically inhibit their growth.
For Chinese gymnast Sang Lan, the cause was a highly publicized headfirst fall during warm-ups for the 1998 Goodwill Games. For Richard Castaldo of Littleton, Colo., it was bullets; for onetime football player Dennis Byrd, a 1992 collision on the field; and for a ...
A clinical trial that would test the use of embryonic stem cells to treat spinal cord injury could begin within three months.
The Scientist is reporting that the Food and Drug Administration (FDA) may lift its hold on a trial sponsored by California biotech Geron Corp. by early ...
ScienceDaily (Oct. 16, 2008) — Researchers in a study funded by the National Institutes of Health (NIH) have demonstrated for the first time that a direct artificial connection from the brain to muscles can restore voluntary movement in monkeys whose arms have been temporarily

These small, feel-good stories have popped up all over the country the past two years, mostly buried on the inside local news pages:
Chicago: Mother of three with MS finds new mobility.
ScienceDaily (Oct. 11, 2008) — In a groundbreaking study led by a molecular biologist at Florida State University, researchers have discovered that as embryonic stem cells turn into different cell types, there are dramatic corresponding changes to the order in which DNA is replicated and...
ScienceDaily (Sep. 19, 2008) — Researchers in Rochester, N.Y., and Colorado have shown that manipulating stem cells prior to transplantation may hold the key to overcoming a critical obstacle to using stem cell technology to repair spinal cord injuries.
Research from a team of scientists from the University of Rochester Medical Center and the University of Colorado Denver School of Medicine, published today in the online...
IBy Roger Highfield, Science Editor- Scientists have found a way to make a kind of cells called astrocytes from embryonic stem cells. Image of adult astrocytes found in untreated adult spinal cord scar tissue. Tests showed that they can coax 40 per cent of severed nerve fibres to regrow in around a week in rats with spinal injuries, restoring the animals' ability to move freely...
