Fluctuation X-ray scattering
In biology, materials science and the energy sciences, structural information provides important insights into the understanding of matter. The link between a structure and its properties can suggest new avenues for designed improvements of synthetic materials or provide new fundamental insights in biology and medicine at the molecular level.

Hydrodynamics approaches to granular matter
Sand, rocks, grains, salt or sugar are what physicists call granular media. A better understanding of granular media is important - particularly when mixed with water and air, as it forms the foundations of houses and off-shore windmills. Until recently, there was no single theory that could account for granular media's flows at different speeds. Now, a new theory dubbed GSH, which stands for granular solid hydrodynamics, is supplementing previous models of granular material that work only for narrow speed ranges. And Yimin Jiang from Central South University, Changsha, China and Mario Liu from the University of Tübingen, Germany have now applied GSH to different experimental circumstances, for a wide range of flow speeds, in a study published in EPJ E.

New way to calculate how long it would take to fall through a hole in the Earth
(Phys.org)—Alexander Klotz a student at McGill University in Canada has calculated a new answer to the commonly asked physics question, how long would it take a person to fall all the way through the Earth? Instead of the commonly accepted 42 minutes, he claims it is 38. He has published his reasoning, math and conclusions in a paper published in The American Journal of Physics.

Using viruses to augment boiling and condensation processes
Legions of viruses that infect the leaves of tobacco plants could be the key to making power plants safer, heating and cooling of buildings more efficient, and electronics more powerful. These tiny protein bundles, which were once a threat to a staple cash crop of the nascent United States in the 1800s, are now helping researchers like Drexel University's Matthew McCarthy, PhD, better understand and enhance the processes of boiling and condensation.

Desalination with nanoporous graphene membrane
Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene -- a carbon honeycomb one atom thick.

Thousands of atoms entangled with a single photon
Physicists have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results represent the largest number of particles that have ever been mutually entangled experimentally.

New form of ice: Square ice filling for a graphene sandwich
Water exists in myriad forms, and for poets and scientists alike this structurally simple yet at the same time behaviourally complex molecule never fails to fascinate. In our everyday lives we are familiar with water in its more common liquid, ice and vapour forms. Scientists also study water under more extreme conditions, including at high pressures, where it can exist in the solid state even at room temperature.
