Researchers advance insights into cause of ripples on icicles

Scientists Narrow the Anchor Point in a Quantum Chromodynamics Critical Point Search
Heavy ion collisions using gold nuclei found a phase of nuclear matter with freely moving quarks and gluons, the Quark Gluon Plasma (QGP). Scientists are aiming to establish if a critical point exists in the phase diagram of nuclear matter, where the QGP would coexist with a gas of protons, neutrons, and other particles. Research at the Relativistic Heavy Ion Collider indicates that if this critical point exists, it is between energies of 3 and 20 giga-electron volts.
Tiny Underwater Sand Dunes May Shed Light on Larger Terrestrial and Martian Formations
In Physics of Fluids, researchers have been studying the dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are commonly found in various sizes and circumstances, on Earth and on Mars. Using a computational fluid dynamics approach, the team carried out simulations by applying the equations of motion to each grain in a pile being deformed by a fluid flow, showing the ranges of values for the proper computation of barchan dunes down to the grain scale.
Nuclear Physics Gets a Boost for High-Performance Computing
Efforts to harness the power of supercomputers to better understand the hidden worlds inside the nucleus of the atom recently received a big boost. A project led by the U.S. Department of Energy's (DOE's) Thomas Jefferson National Accelerator Facility is one of three to split $35 million in grants from the DOE via a partnership program of DOE's Scientific Discovery through Advanced Computing (SciDAC). The $13 million project includes key scientists based at six DOE national labs and two universities, including Jefferson Lab, Argonne National Lab, Brookhaven National Lab, Oak Ridge National Lab, Lawrence Berkeley National Lab, Los Alamos National Lab, Massachusetts Institute of Technology and William & Mary.

Microplastics could make other pollutants more harmful
On their own, microplastics are potentially harmful, and it's unclear what effect they could have on pollutants. Now, researchers reporting in ACS' Environmental Science & Technology Letters show that, when attached to microplastics, UV filters in sunscreens can make chromium metal more toxic.
Planetary science: Mars megatsunami may have been caused by Chicxulub-like asteroid impact
A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact - which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago - in a shallow ocean region, according to a study published in Scientific Reports.
