Human neurons grown as cells cloned from a tumor helped restore the function of severely injured spinal cords in rats, University of South Florida researchers say in a study released this week in the Journal of Neurosurgery: Spine.
"Transplants of these specially treated cells were used to patch a short circuit in the spinal cord of rats," said Samuel Saporta, PhD, associate director of the USF Center for Aging and Brain Repair, professor of anatomy and lead author of the study. "We demonstrated the cells are safe, survive and can electrically reconnect the undamaged parts of the spinal cord."
A couple of the spinal cord-injured (SCI) rats could bear weight on their hind legs following transplantation with the experimental cells, known commercially as hNT, or LBS, neurons. However, the researchers emphasize, more studies are needed to determine if rats with reconnected spinal cords can walk again.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
