A lipid that helps destroy potentially harmful cells during brain development shows promise for improving the safety and efficacy of stem cell transplants, say researchers at the Medical College of Georgia and University of Georgia.
When embryonic stem cells are being coaxed toward becoming brain cells that could be transplanted, that lipid, ceramide, helps eliminate cells that could later form tumors called teratomas, researchers say in the Nov. 22 issue of The Journal of Cell Biology.
“The body has amazing mechanisms to eliminate cells that are no longer wanted and that if they remain will harm the body by developing into tissues that are not meant to be,” says Dr. Erhard Bieberich, MCG biochemist and the study’s lead author. “Our studies show this particular mechanism can help stem cells safely become the cells we want them to be.” “This is another approach to controlling differentiation and getting the cell types that you want,” says Dr. Brian G. Condie, developmental neurobiologist at UGA and MCG and senior author on the paper.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
