Timing of childbirth cited as key factor
Europe’s population has aged to such a degree that it will likely continue to shrink, even if birthrates rebound to a one-for-one replacement level, a new study suggests. A major part of this trend is due to the fact that women have been postponing childbirth for increasing lengths of time, the authors have found. Their research appears in the journal Science, published by the American Association for the Advancement of Science (AAAS).
The year 2000 marked a key turning point for Europe, reports the research team, led by Wolfgang Lutz of the Austrian Academy of Science, in Vienna, and the International Institute for Applied Systems Analysis, in Laxenburg, Austria.

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...
