Particle energy spectra can distinguish black holes from compact massive objects

Scientists from Moscow Institute of Physics and Technology, the Institute for Theoretical and Experimental Physics, and the National Research University Higher School of Economics have devised a method of distinguishing black holes from compact massive objects that are externally indistinguishable from one another. The method involves studying the energy spectrum of particles moving in the vicinity, which can be continuous or discrete. The findings have been published in Physical Review D.

Spacecraft Juno nears planet orbit, but Harvard team may already have predicted part of what it will find

In less than a week, the spacecraft Juno will arrive at Jupiter, the culmination of a five-year, billion-dollar journey. It's mission: to peer deep inside the gas giant and unravel its origin and evolution. One of the biggest mysteries surrounding Jupiter is how it generates its powerful magnetic field, the strongest in the solar system.

NASA Television to Air Next International Space Station Crew Launch

The next three crew members bound for the International Space Station are set to launch Wednesday, July 6. Live launch coverage will begin at 8:30 p.m. EDT on NASA Television and the agency's website.

Role played by solvents at extreme pressure

Researchers investigated the behavior of the small molecule TMAO in water from normal conditions up to ten kilobars. Experiment and simulation showed that some bands in the infrared spectrum shift to higher frequencies at high pressure and also change their shape due to a change in the hydrogen bond network. Such findings open up the prospect of helping to understand how organisms have adapted at the molecular level to life under extreme pressures.

Brilliant hard drive quality with magnetic field sensors made of diamond

Quantum mechanics is not only of high interest in fundamental research. The current progress in quantum technologies promises numerous innovations of industrial relevance, which will be transferred into the economy within the next five to ten years. Researchers are now developing highly sensitive diamond probes as a basis for novel quantum sensors. These are able to characterize smallest magnetic fields with a spatial resolution in the nanometer range.

Recreating lightning for research

Sandia National Laboratories creates lightning in a lab to evaluate how anything from sensitive nuclear weapons components to entire buildings will hold up against the worst that nature might throw at them.

Virus particles in a doughnut-shaped chamber form fixed patterns

Large biomolecules in a small space spontaneously form symmetrical patterns. Researchers from FOM institute AMOLF discovered this together with colleagues from Oxford and Jülich when they confined rod-shaped virus particles in doughnut-shaped micro-chambers. What started as a chance discovery has opened up a whole new area in the physics of ultrasmall liquid crystal cells with potential applications in new displays. The results of the research will be published on June 29 2016, in Nature Communications.
