Tube worms living at deep-sea oil seeps in the Gulf of Mexico significantly alter their habitat, similar to beavers altering the flow of a river. Researchers from Pennsylvania State University have just published an important finding in the journal Ecology Letters.
A computer model of tube worm aggregations was created for Lamellibrachia luymesi, which is among the longest lived animals known. Both actual and model populations persist for centuries and take up high quantities of sulfide from seep sediments.
Tube worms live off sulfide (the toxic chemical responsible for the smell of rotten eggs) by supplying it to internal bacteria which use sulfide as an energy source. To acquire sulfide, this tube worm grows "roots" through carbonate rock and into the sediment below. The roots deplete sulfide from the sediment, effectively preventing sulfide from seeping into the bottom water.

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...
