AAAS 2016: SLAC Scientists to Participate in Discussion on Global Search for Dark Matter

The world we see is embedded in an invisible cosmic web of dark matter – a ghostly form of matter that doesn’t emit light and rarely bumps into things. Although no one has ever directly observed the mysterious substance, scientists have seen signs of its existence because its gravity pulls on ordinary matter – the stuff we’re made of. In fact, it seems to be the scaffolding on which galaxies are built. Without dark matter, which is five times more prevalent than normal matter, the universe would look quite different: neither we nor our Milky Way would be around today.

New Way to Generate Very Low-Resistance Electric Current Relies on Chiral Magnetic Effect

Scientists at the U.S Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a new way to generate very low-resistance electric current in a new class of materials. The discovery, which relies on the separation of right- and left-"handed" particles, points to a range of potential applications in energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity—the ability of some materials to carry current with no energy loss.

Researchers Non-Destructively Measure Quantum State of Molecular Ion for First Time

The interaction of thermal energy from the environment with motional degrees of freedom is well known and often referred to as Brownian motion (also thermal motion). But in the case of polar molecules, the internal degrees of freedom - in particular the rotational quantum state - are also influenced by the thermal radiation. So far, the detection of the rotational state was only possible by destroying the molecule.

Scientists Use Preliminary Reference Earth Model to Study Interior of Earth-Like Structures

Every school kid learns the basic structure of the Earth: a thin outer crust, a thick mantle, and a Mars-sized core. But is this structure universal? Will rocky exoplanets orbiting other stars have the same three layers? New research suggests that the answer is yes - they will have interiors very similar to Earth.

Scientists Create Quantum Switch by Pinning Photon and Electron Together in Small Space

Scientists have created a crystal structure that boosts the interaction between tiny bursts of light and individual electrons, an advance that could be a significant step toward establishing quantum networks in the future.

Saturn’s B-Ring is Opaque Yet Lightweight, Researchers Confirm

After examining hidden density waves from Saturn’s B-ring – the largest of the planet’s awe-inspiring, cosmic bands – astronomers confirm that this circular object is as lightweight as it is opaque. Their findings are published online in the journal Icarus.

Multiple Time Stepping Techniques Can Help Simulate Quantum Nature of Light Nuclei

Simulating the quantum nature of light nuclei, such as hydrogen or lithium, without compromising on the description of the electronic structure of materials and molecules, can now be achieved by combining multiple time stepping techniques in real and imaginary time.

New Research Shows Formation and Evolution of Stars

Stars do not accumulate their final mass steadily, but in a series of violent events manifesting themselves as sharp stellar brightening. According to this theory of Eduard Vorobyov from the University of Vienna, stellar brightening can be caused by fragmentation due to gravitational instabilities in massive gaseous disks surrounding young stars, followed by migration of dense gaseous clumps onto the star. This "Cannibalism", as Vorobyov describes his model prediction, was verified for the first time thanks to advanced observational instruments. The results are now published in "Science Advances".

Evidence for New Astrophysical Source of Gamma Rays at Galactic Center

Contrary to the assumption that bursts of gamma rays emanating from our galaxy’s center are dark matter signals, it is now thought that they could be fast-rotating stars, known as millisecond pulsars, or other astrophysical phenomena, in accordance with the results of two recent studies.
