As interest and demand for nanotechnology continues to rise, so will the need for nanoscale printing and spraying, which relies on depositing tiny drops of liquid onto a surface. Now researchers from Tsinghua University in Beijing have developed a new theory that describes how such a nanosized droplet deforms and breaks up when it strikes a surface.

The Virginia Tech Hyperloop team will head to Hawthorne, CA to go head-to-head against 28 of the best teams from around the world.
For years, B. Ubbo Felderhof, RWTH Aachen University, has explored the mechanisms fish and microorganisms rely on to propel themselves. He has created mechanical models to support the theory behind the “swimming” of microorganisms, consisting of linear chains of spheres connected by springs and immersed in fluid, and he’s just pushed this work even further by addressing what happens when adding one sphere to the chain that’s much larger than the others.
PPPL physicist Fatima Ebrahimi has published a paper showing that magnetic reconnection — the process in which magnetic field lines snap together and release energy — can be triggered by motion in nearby magnetic fields.
Professor Alexander Zamolodchikov became the inaugural Chen Ning Yang – Wei Deng Endowed Chair in Physics and Astronomy on January 6 at an investiture ceremony in Beijing, China at the global headquarters of Bright Ocean’s Corporation.

Shrinking the investigation of objects to the nanometer scale often reveals new properties of matter that have no equivalent for their bulk analysis. This phenomenon is motivating studies of nanomaterials which can reveal fascinating new phenomena. It inspired researchers to explore the extent of knowledge about fundamental properties of fluids, which demands reconsideration with the increasing use of fluids in the decreasing sizes of new devices, where their flow is confined into ever-smaller capillary tubes.

Nearly a thousand computer simulations by the Weizmann Institute’s Prof. Oded Aharonson and his team produced results challenging the theory that the Moon was formed by a single massive collision; rather, the investigation shows, the more likely explanation is that multiple impacts produced many moonlets, which coalesced into our solitary satellite.
A black hole studied and discovered by Peter Boorman, PhD researcher at the University of Southampton, is so hidden that it requires highly sensitive observations in the highest energy X-rays to classify it as obscured. But they give themselves away when material they feed on emits high-energy X-rays that NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) mission can detect. That's how University of Southampton PhD researcher Peter Boorman used NuSTAR to recently identify a gas-enshrouded supermassive black holes located at the centres of nearby galaxy IC 3639 some 175 million light years from Earth.
Astronomers were surprised to see a huge shadow sweeping across a disk of dust and gas encircling the nearby, young star TW Hydrae. They have a bird's-eye view of the disk, because it is tilted face-on to Earth, and the shadow sweeps around the disk like the hands moving around a clock. But, unlike the hands of a clock, the shadow takes 16 years to make one rotation. Hubble has 18 years' worth of observations of the star; therefore, astronomers could assemble a time-lapse movie of the shadow's rotation.
Interstellar forecast for a nearby star: Raining comets! The comets are plunging into the star HD 172555, which resides 95 light-years from Earth. The comets were not seen directly around the star. Astronomers inferred their presence when they used NASA's Hubble Space Telescope to detect gas that is likely the vaporized remnants of their icy nuclei.

List of the top 10 laboratory stories in 2016.
Love it or hate it, you've probably at least heard of CBS’s hit TV show “The Big Bang Theory,” now in its 10th year of production. But how accurately does it portray scientific culture, and does it break or reinforce stereotypes? A free article in this month’s edition of Physics Today and a companion Inside Science video interview with its author explore these questions.
Thanks to a new development in nuclear physics theory, scientists exploring expanding fireballs that mimic the early universe have new signs to look for as they map out the transition from primordial plasma to matter as we know it. The theory work, described in a paper recently published as an Editor's Suggestion in Physical Review Letters (PRL), identifies key patterns that would be proof of the existence of a so-called “critical point” in the transition among different phases of nuclear matter.
Cornell University researchers and a global team of astronomers have uncovered the cosmological source of a sporadically repeating milliseconds-long “fast radio burst.”

Collaborative team report on first precision study of antihydrogen
Released today in the prestigious journal Nature, the collaboration reports on the first spectroscopic measurement of an atom of antimatter using lasers. ALPHA is an international team of researchers, including the ALPHA-Canada group, which studies antihydrogen, the antimatter partner to hydrogen. Their latest work represents a major step towards developing a very precise test of whether antimatter behaves differently than its normal matter anti-twin, thus opening up a promising new front to address the basic antimatter question: “if matter and antimatter were created equally during the Big Bang, where is all the antimatter?”
A team of researchers in Italy set out to develop a simple, ultrasensitive fluorescence detection system of in-flow microRNAs that uses spectrally encoded microgels. As the team reports in Biomicrofluidics, until now such a multiplexed barcode detection approach has only been performed in time-consuming observation procedures, significantly hindering its possible diagnostic performance.

In a paper published in Nature Physics, a team of researchers from the Georgia Institute of Technology, the University of Tennessee and the Department of Energy’s Oak Ridge National Laboratory used neutrons to examine the origins of unusual magnetic behavior in a rare earth–based metal oxide, ytterbium-magnesium-gallium-tetraoxide (YbMgGaO4). The material, discovered in 2015, is known to have strange magnetic properties, putting it in a unique category of materials classified as quantum spin liquids.
