Monte Carlo results confirm the body-centered cubic structure as an unstable phase for hard spheres and identify a mechanically stable amorphous crystalline structure. #scilight
The pressure inside a neutron star is immense. Imagine the mass of a sun-sized star packed inside an object with the width of a city. How would matter be impact...ed by these superdense conditions? LIGO’s recent discovery of a neutron star collision, along with other recent breakthroughs, has researchers hopeful an answer is in sight.

Although liquid metals are effective fluids for heat transfer, pumping them at high temperatures is limited by their corrosiveness to solid metals. A clever pump design described in Nature addresses this challenge using only ceramics. This News & Views article discusses the findings.

Hydrogen is the most abundant element in the Universe, and it experiences extreme pressures in stars and in gas giant planets. Now researchers at the Carnegie I...nstitution for Science have managed to accurately measure hydrogen's melting point at pressures up to 300 GPa (3 million times atmospheric pressure) finding results that contradict theoretical predictions, explain physicists Peter Celliers and Jon Eggert of Lawrence Livermore National Laboratory.
Congratulations to Professor Changqing Jin (Institute of Physics, Chinese Academy of Sciences), elected Chairman of the Commission for Crystallography of Materials, a permanent commission of the International Union of Crystallography. Professor Changqing Jin was Chairman of the 2017 AIRAPT Conference, which has just finished in Beijing, China.
Water and methane do mix, but at high pressure
Researchers demonstrate 'diamond showers' forming in the ice giants of our solar system. Using an ultra-strong X-ray laser to simulate conditions inside the cos...mic giants, they observed the fission of hydrocarbon and the conversion of carbon into diamonds in real time. The results are published in Nature Astronomy.
