Spiral laser beam creates quantum whirlpool
(Phys.org) —Physicists at Australian National University have engineered a spiral laser beam and used it to create a whirlpool of hybrid light-matter particles called polaritons.
Granular model explains unusual behavior in sand
From a mechanical perspective, granular materials are stuck between a rock and a fluid place, with behavior resembling neither a solid nor a liquid. Think of sand through an hourglass: As grains funnel through, ...
Mission to discover hundreds of black holes could unlock secrets of the Universe
A team of Cardiff University researchers have made a breakthrough in helping scientists discover hundreds of black holes throughout the universe.
Molecules in a fluid not randomly arranged
FOM PhD researcher Matthijs Panman and his colleagues from the University of Amsterdam have demonstrated that molecules in liquid alcohol are not randomly oriented with respect to each other. The angle between ...
Researchers find viscoelastic fluids form wings when shot out of a jet at close range
The mystery of pulsar rarity at the center of our galaxy
The galactic center is a happening place, with lots of gas, dust, stars, and surprising binary stars orbiting a supermassive black hole about three million times the size of our sun. With so many stars, as ...
Scientists prove possibility of 'impossible' dust transition in turbulent flow
Researchers from MIPT and the Weizmann Institute of Science (Israel) have predicted the possibility of negative turbophoresis, a phenomenon where impurity particles inside a turbulent flow move in an "impossible" ...
Researchers find magnetic state of atoms on graphene sheet impacted by substrate it's grown on
Proton spin puzzle: Research reveals gluons make a significant contribution to spin
Results from experiments at the Relativistic Heavy Ion Collider (RHIC), a particle collider located at the U.S. Department of Energy's Brookhaven National Laboratory, reveal new insights about how quarks ...

Universe may face a darker future
New research offers a novel insight into the nature of dark matter and dark energy and what the future of our Universe might be.
Biology meets geometry: Describing geometry of common cellular structure
Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ...
