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. [30] 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. [29] 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. [28] In nature, the nuclear reactions that form stars are often accompanied by astronomically high amounts of energy, sometimes over billions of years. [27] Dark matter halos are theoretical bodies inside which galaxies are suspended; the halo's mass dominates the total mass. [26] 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). [25] 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. [24] 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. [23] Quark matter – an extremely dense phase of matter made up of subatomic particles called quarks – may exist at the heart of neutron stars. [22] 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. [21] 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.
