Scientists at Northwestern University have designed synthetic molecules that promote neuron growth, a promising development that could lead to the reversal of paralysis due to spinal cord injury.
"We have created new materials that because of their chemical structure interact with cells of the central nervous system in ways that may help prevent the formation of the scar that is often linked to paralysis after spinal cord injury," said Samuel I. Stupp, Board of Trustees Professor of Materials Science and Engineering, Chemistry and Medicine.
Similar to earlier experiments that promoted bone growth, the scientists now have successfully grown nerve cells using an artificial three-dimensional network of nanofibers, an important technique in regenerative medicine. The results will be published online Jan. 22 by the journal Science.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
