A new study from the Cava lab has revealed a unifying connection between seemingly unrelated materials that exhibit extreme magnetoresistance, the ability of some materials to drastically change their electrical resistance in response to a magnetic field, a property that could be useful in magnetic memory applications.

A physics experiment performed at the National Institute of Standards and Technology (NIST) has enhanced scientists’ understanding of how free neutrons decay into other particles. The work provides the first measurement of the energy spectrum of photons, or particles of light, that are released in the otherwise extensively measured process known as neutron beta decay

(Phys.org)—The relationship between communication complexity problems, Bell nonlocal correlations and the advantage of quantum over classical strategies has long been recognized, but has been confirmed in only two problems. Recently, however, scientists at University of Cambridge, University of Amsterdam, CWI, QuSoft, Gdansk University, Gdansk University of Technology, Adam Mickiewicz University, and Jagiellonian University employed a two-part method based on port-based teleportation – a scheme of quantum teleportation where a receiver has multiple (N) output ports and obtains the teleported state by merely selecting one of the N ports1,2

Professor Chris Arumainayagam will announce findings from his research conducted at Wellesley College today, Monday, June 13, as part of the annual press briefings kicking off the American Astronomical Society (AAS) national conference in San Diego, Calif. Arumainayagam, a professor of chemistry at Wellesley, will discuss his work—the first systematic study to demonstrate that early building blocks of life may be produced when low-energy (< 20 eV) electrons interact with cosmic (interstellar, planetary, and cometary) ices.

In the 2015 movie “The Martian,” stranded astronaut Matt Damon turns to the chemistry of rocket fuel, hydrazine and hydrogen, to create lifesaving water and nearly blows himself up. But if you turn the process around and get the hydrazine to help, you create hydrogen from water by changing conductivity in a semiconductor, a transformation with wide potential applications in energy and electronics.

Terahertz radiation—the band of electromagnetic radiation between microwaves and visible light—has promising applications in security and medical diagnostics, but such devices will require the development of compact, low-power, high-quality terahertz lasers.

In a multinational collaboration, researchers from the Universities of Luxembourg, Ljubljana and Vienna have developed a new method to produce unique reflecting patterns that can be applied on valuable objects. As these patterns can’t be cloned or copied, they could be used to identify products unambiguously in order to avoid counterfeiting.

Knowledge of the minute details of the proteins that are linked to diseases is crucial if we are to discover therapeutic targets and thus pave the way for possible treatments. Such knowledge gains even more relevance when dealing with rare diseases that have received little attention and for which no treatments are available, such as the case of Kennedy’s disease.

Physicists at the National Institute of Standards and Technology (NIST) have “entangled” or linked together the properties of up to 219 beryllium ions (charged atoms) to create a quantum simulator. The simulator is designed to model and mimic complex physics phenomena in a way that is impossible with conventional machines, even supercomputers.

Scientists working for Murdoch University, the Wildlife Conservation Society, The Nature Conservancy, and other groups have good news about fishing closures established in Indonesia’s shark sanctuary: It’s good for sharks and other fish, all of which are more abundant within zones with fishing restrictions.
