Weizmann Institute scientists reveal key part of nerve regeneration mechanism
A new study conducted by Weizmann Institute scientists has now uncovered a key process leading to the regeneration of peripheral nerves. Nerves in the peripheral nervous system (any part of the body aside from the brain and spinal cord) are capable of regenerating, though often they do so poorly or slowly. Scientists have been trying to understand how they regenerate in order to better treat damage to the peripheral nervous system.
In addition, knowing how these neurons regenerate could provide insights into fixing neurons in the central nervous system where damage is irreversible.
Nerve cells are uniquely shaped, consisting of a cell body from which a long "arm," called an axon, extends. Axons can reach up to one meter in length and are the main conduit for nerve communication throughout our bodies, by conveying electric signals to muscles or other cells. Due to their great length, axons, like electrical or telecommunications lines, are vulnerable to damage. When a power line goes down in a storm, monitoring systems raise the alarm and repair crews are dispatched to the site. How does an axon raise the alarm after damage in our own bodies?

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
