SLAC’s Upgraded High-Power Laser Could Help Recreate Universe’s Most Extreme Conditions

A newly upgraded high-power laser at the Department of Energy’s SLAC National Accelerator Laboratory will blaze new trails across many fields of science by recreating the universe’s most extreme conditions, such as those at the heart of stars and planets, in a lab.

Superconductivity Could Promote Magnetization Under Certain Conditions

Superconductivity, which is almost incompatible with magneticfield, under certain conditions is able to promote magnetization. Russian scientist Natalya Pugach from the Skobeltsyn Institute of Nuclear Physics at the Lomonosov Moscow State University discovered this yet to be explained effect with her British colleagues, whose theory group headed by Professor Matthias Eschrig.

Physicists Demonstrate Games of Quantum Billiards with Unusual New Rules

Physicists have wondered in recent years if they could control how atoms interact using light. Now they know that they can, by demonstrating games of quantum billiards with unusual new rules.

Most Comprehensive Images of Milky Way's Star-Forming Clouds

Astronomers have long turned their telescopes, be they on satellites in space or observatories on Earth, to the wide swaths of interstellar medium to get a look at the formation and birth of stars.

Researchers Successfully Record Structures of Electron Orbitals in 3D

Many of you will remember them from your physics lessons at school: often represented as colourful clouds or balloons, electron orbitals provide information on the whereabouts of the electrons in atoms and molecules.

New Method to Measure Mass of Pulsars

Researchers from the University of Southampton have developed a new method for measuring the mass of pulsars - highly magnetised rotating neutron stars formed from the remains of massive stars after they explode into supernovae.

Proton-Lead Collisions Produce Smaller Liquid Droplets

This existential question has been raised by a series of experiments conducted recently at the Large Hadron Collider and the Relativistic Heavy Ion Collider that smash various atomic particles together at nearly the speed of light in order to create tiny drops of primordial soup.

Researchers Clarify Unique Nature of Electron Partitioning Process in Graphene

A group of researchers from Osaka University, The University of Tokyo, Kyoto University, and the National Institute for Materials Science precisely conducted current-fluctuation (“shot noise”) measurement in the graphene p–n junction in the quantum Hall regime. This group found that the non-zero shot noise appears in the bipolar regime of the junction, while the noise is absent in the unipolar regime. This clearly tells that the electron partition process exists at the co-propagating edge states along the p–n junction. This group's achievement, which is consistent with the theory predicted in 2008, gives microscopic evidence that the edge states are mixed along the junction for the first time. This is an important step toward clarifying the unique nature of the electron partition process in graphene and designing new-type electron interferometer devices using graphene in the quantum Hall regime.

Rosetta Observes Dark Side of Comet 67P/Churyumov-Gerasimenko

Since its arrival at comet 67P/Churyumov-Gerasimenko, the European Space Agency's Rosetta spacecraft has been surveying the surface and the environment of this curiously shaped body. But for a long time, a portion of the nucleus -- the dark, cold regions around the comet's south pole -- remained inaccessible to almost all instruments on the spacecraft.

Experiments Provide New Insights into the Building Blocks of Matter

Scientists intent on unraveling the mystery of the force that binds the building blocks of visible matter are gathered in Kobe, Japan, this week to present and discuss the latest results from "ultrarelativistic nucleus-nucleus collisions." Known more colloquially as Quark Matter 2015, the conference convenes scientists studying smashups of nuclei traveling close to the speed of light at the world's premier particle colliders--the Relativistic Heavy Ion Collider (RHIC, https://www.bnl.gov/rhic/) at the U.S. Department of Energy's Brookhaven National Laboratory, and the Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN).
