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).

Researchers Evaluate Behavior of Specific Atoms to Better Understand Dielectric Materials

Researchers from North Carolina State University, the National Institute of Standards and Technology (NIST), and UNSW Australia have measured the behavior of specific atoms in dielectric materials when exposed to an electric field. The work advances our understanding of dielectric materials, which are used in a wide variety of applications - from handheld electronics to defibrillators.

Black-Hole Singularity: A Look Back at the Theorem

When a star collapses forming a black hole, a space-time singularity is created wherein the laws of Physics no longer work. In 1965 Sir Roger Penrose presented a theorem where he associated that singularity with so-called ''trapped surfaces'' that shrink over time. That hypothesis -one of the results of the general theory of relativity- is now celebrating its anniversary.

Tiny Robots hold Optical Fibers in Position to Create 3D Map of Galaxies

Why is the universe expanding at an increasing rate? Scientists will attempt to gain a better understanding of this phenomenon by mapping the distribution of galaxies in the universe. Astrophysicists and robotics engineers from EPFL are taking part in this scientific adventure.

Most Stable Light Source to Study Exoplanets

In order to be able to detect planets comparable to Earth, the CHEOPS satellite, which will be sent into orbit at the end of 2017, must be able to measure the luminosity of a star with inimitable accuracy. In order to test CHEOPS detectors researchers need a stable source of light. However there was no instrument capable of producing a light source with sufficient stability to be used as a reference… until today. A team from the University of Geneva (UNIGE), Switzerland, has just filed for a European patent.

Ambitious AIDA Mission Aims to Divert Orbit of Didymos Asteroid’s Didymoon

An ambitious joint US-European mission, called AIDA, is being planned to divert the orbit of a binary asteroid’s small moon, as well as to give us new insights into the structure of asteroids. A pair of spacecraft, the ESA-led Asteroid Impact Mission (AIM) and NASA-led Double Asteroid Redirection Test (DART), will rendezvous with the Didymos asteroid and its small natural satellite, known informally as ‘Didymoon’.
