A signal that triggers half the stem cells in the developing brain to commit suicide at a stage where their survival will likely do more harm than good has been identified by researchers at the Medical College of Georgia and the University of Georgia.
Identifying the factors that result in the timely, massive cell suicide is important to understanding the developmental puzzle, the researchers say of the work featured on the cover of the Aug. 4 issue of the Journal of Cell Biology.
They say it also gives clues about cell death - and the brain´s possible recovery - in devastating diseases such as Alzheimer´s, Parkinson´s and stroke. MCG´s Erhard Bieberich and UGA´s Brian G. Condie have found that the lipid ceramide and the protein PAR-4 - each already implicated for playing a role in cell death - become deadly partners inside a dividing stem cell in the developing mouse brain.

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
