PPPL Physicist Uncovers Clues to Mechanism Behind Magnetic Reconnection

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.

The Science of Consciousness, June 5-10, 2017

'The Science of Consciousness' ('TSC') is the world's largest and longest-running interdisciplinary conference on all aspects of the nature of conscious awareness, feelings and existence.

Zamolodchikov Invested as C.N. Yang Endowed Chair in Physics and Astronomy

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. A pioneer in modern theoretical physics and member of the National Academy of Sciences, Prof. Zamolodchikov is known internationally for his contributions to the study of condensed matter physics, conformal field theory and string theory. His impact on the field of physics can be measured by a simple metric: 18,000 -- the number of times his published research has been cited; one of the highest in physics to date.

Astronomers Find Seven Dwarf-Galaxy Groups, the Building Blocks of Massive Galaxies

A team of astronomers has discovered seven distinct groups of dwarf galaxies with just the right starting conditions to eventually merge and form larger galaxies, including spiral galaxies like the Milky Way.

Kawtar Hafidi Named Director of Physics Division

Argonne associate chief scientist Kawtar Hafidi has been named Argonne National Laboratory's next physics division director.

Melting Solid Below the Freezing Point

Phase transitions surround us--for instance, liquid water changes to ice when frozen and to steam when boiled. Now, researchers at the Carnegie Institution for Science* have discovered a new phenomenon of so-called metastability in a liquid phase. A metastable liquid is not quite stable. This state is common in supercooled liquids, which are liquids that cool below the freezing point without turning into a solid or a crystal. Now, scientists report the first experimental evidence of creating a metastable liquid directly by the opposite approach: melting a high-pressure solid crystal of the metal bismuth via a decompression process below its melting point.

Neutrons and a 'Bit of Gold' Uncover New Type of Quantum Phase Transition

In a paper published in Physical Review Letters, a team of researchers led by the Department of Energy's Oak Ridge National Laboratory reports the discovery of a new type of quantum phase transition. This unique transition happens at an elastic quantum critical point, or QCP, where the phase transition isn't driven by thermal energy but instead by the quantum fluctuations of the atoms themselves.

You Are in Command as NRAO's 'Orion Explorer' Tours This Iconic Constellation

NRAO announces its newly released Orion Explorer installment of its popular Milky Way Explorer, an online tour of our interstellar neighborhood guided by the actual astronomers who study it using radio waves.

Call for Entries: Awards for Science Writing

The American Institute of Physics (AIP) and the Acoustical Society of America (ASA) are both accepting submissions for their respective 2017 science writing awards. The deadline for entries for both awards is March 31, 2017.

NASA Reviewing $239 Million UAH-Led Proposal for Lunar Astrophysics Mission

Next-generation astrophysics research using the moon as home base and The University of Alabama in Huntsville (UAH) as its world-class data center are the goals of a multiyear, $237 million NASA satellite mission proposed by a UAH astrophysicist's collaborative group.

A Quark Like No Other

A University of Iowa physicist is at the forefront of the search to confirm the existence of a particle believed to give mass to all matter. Her group helped build and operates a sub-detector to search for bottom quarks, which are thought to appear when a Higgs boson decays.

Biophysics Plays Key Role in Immune System Signaling and Response

How big you are may be as important as what you look like, at least to immune system cells watching for dangerous bacteria and viruses.

Image Release: ALMA Reveals Sun in New Light

New images from ALMA reveal stunning details of our Sun, including the dark, contorted center of an evolving sunspot nearly twice the diameter of the Earth.

Cellular Podiatry

A study by researchers from the labs of Prof Alexander Bershadsky at the Mechanobiology Institute, Singapore and Prof Gareth E Jones at King's College London has revealed that a protein known as Arf1 plays a role in podosome formation by regulating the assembly of myosin-II within the cytoskeleton.

Notre Dame Astrophysicists Discover Dimming of Binary Star

A team of University of Notre Dame astrophysicists has observed the unexplained fading of an interacting binary star, one of the first discoveries using the Sarah L. Krizmanich Telescope.

Undergrads Lend a Hand in Unlocking Universe's Secrets

Students from California join in cutting-edge research at the Large Hadron Collider in Geneva.

NUS Researchers Achieve Major Breakthrough in Flexible Electronics

A team of scientists from the National University of Singapore has successfully developed conducting polymer films that can provide unprecedented ohmic contacts to give superior performance in plastic electronics, including organic light-emitting diodes, solar cells and transistors.

Blended Galaxies

Galaxies are merging all the time, even our own galaxy, the Milky Way. But how these mergers occur isn't entirely clear. University of Iowa astrophysicist Hai Fu will use a National Science Foundation grant to find and characterize supermassive black holes associated with merging galaxies.

Sketching Out Magnetism With Electricity

In a proof-of-concept study published in Nature Physics, researchers drew magnetic squares in a nonmagnetic material with an electrified pen and then "read" this magnetic doodle with X-rays.
