Using transplants of bone marrow cells improved the recovery from stroke in rat experiments, according to a study published in the August 27 issue of Neurology, the scientific journal of the American Academy of Neurology.
The rats treated with an intravenous transplant of adult human stromal cells (mature cells from bone marrow) had significant improvements in their ability to function 14 days after the stroke, compared to rats that did not receive transplants after a stroke.
"These are smart cells that selectively migrate to the site of injury and become little factories producing an array of helpful molecules to repair the tissue," said study author Michael Chopp, PhD, of Henry Ford Hospital in Detroit, Mich., and Oakland University in Rochester, Mich. "We believe this therapy shows promise in treating stroke, Parkinsons disease, spinal cord injury and traumatic brain injury."

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
