Oxidative stress is implicated in a fast-growing list of human conditions, from the superficial (e.g., wrinkled skin) to the deadly: diseases such as cancer, heart disease and neurodegenerative disorders including Lou Gehrigs disease (amyotrophic lateral sclerosis or ALS).
Researchers at The Jackson Laboratory announced that they have located a gene that protects certain brain and retinal neurons from oxidative stress, and prevents neurodegeneration.
Many normal metabolic functions produce free radicals--highly unstable forms of oxygen. Despite their notoriety, these molecules in fact have several beneficial roles, such as helping white blood cells attack bacteria, viruses and virus-damaged cells. Oxidative stress occurs when the amount of free radicals exceeds the normal antioxidant capacity of a cell, leading to cell damage.

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...
