A team of researchers at Physique et Mécanique des Milieux Hétérogènes in France has found that Leidenfrost effect drops move around on a hot pan because they are self-propelled.  The researchers, led by Hans-Jurgen Bütt at the Max Planck Institute for Polymer Research in Mainz, Germany, have published a paper on their experimental results in a recent issue of Physical Review Letters.  400 kilometers above Earth, researchers examined waves in complex plasma under microgravity conditions and found that the microparticles behaved in nonuniform ways in the presence of varying electrical fields.  In nature, the nuclear reactions that form stars are often accompanied by astronomically high amounts of energy, sometimes over billions of years.  Dark matter halos are theoretical bodies inside which galaxies are suspended; the halo's mass dominates the total mass.  An international team of researchers extended their results from a previous study to directly measure the cosmic-ray all-electron (electron + positron) spectrum in an energy range from 11 GeV to 4.8 TeV with the Calorimetric Electron Telescope (CALET).  Mysterious radiation emitted from distant corners of the galaxy could finally be explained with efforts to recreate a unique state of matter that blinked into existence in the first moments after the Big Bang.  Researchers at Oregon State University have confirmed that last fall's union of two neutron stars did in fact cause a short gamma-ray burst.  Quark matter – an extremely dense phase of matter made up of subatomic particles called quarks – may exist at the heart of neutron stars.  When a massive astrophysical object, such as a boson star or black hole, rotates, it can cause the surrounding spacetime to rotate along with it due to the effect of frame dragging.  Rotating black holes and computers that use quantum-mechanical phenomena to process information are topics that have fascinated science lovers for decades, but even the most innovative thinkers rarely put them together.
