Educators and scientists should discard the idea that a cells nucleus is just a bag of chromosomes, according to Johns Hopkins cell biologist Kathy Wilson, Ph.D. In a Feb. 17 session at the annual meeting of the American Association for the Advancement of Science (AAAS) in Denver, Wilson and five others will introduce visual evidence of the nucleuss newly recognized importance.
"The old view is that the nucleus is simply a warehouse for chromosomes," says Wilson, associate professor of cell biology in the Johns Hopkins School of Medicines Institute for Basic Biomedical Sciences. "But new research and imaging techniques show that the nucleus is really the cells mothership, a crucial and very active source of information, support and control."
Its not too surprising that the nucleus itself has been overshadowed by the easy-to-see reams of genetic material and the fascinatingly tiny machinery that loosens, prepares, reads and copies genes. But in the last 10 or 15 years, evidence has mounted that these interior processes are actively linked to the nucleus, not just randomly taking place inside it, says Wilson, also chair of the public information committee of the American Society for Cell Biology, which helped organize the session.

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...
