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.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
