Physics news

	A quantum memory that operates at telecom wavelengths To create large quantum networks, researchers will first need to develop efficient quantum repeaters. A key component of these repeaters are quantum memories, which are the quantum-mechanical equivalents of more conventional computer memories, such as random-access memories (RAM).
	Newly observed phenomenon could lead to new quantum devices An exotic physical phenomenon known as a Kohn anomaly has been found for the first time in an unexpected type of material by researchers at MIT and elsewhere. They say the finding could provide new insights into certain fundamental processes that help determine why metals and other materials display the complex electronic properties that underlie much of today's technology.
	Why pulsars shine bright: A half-century-old mystery solved When Jocelyn Bell first observed the emissions of a pulsar in 1967, the rhythmic pulses of radio waves so confounded astronomers that they considered whether the light could be signals sent by an alien civilization.
	Researchers create first room-temp 'magnon switch' with industrially useful properties Scientists at the National Institute of Standards and Technology (NIST) and the Massachusetts Institute of Technology (MIT) have demonstrated a potentially new way to make switches inside a computer's processing chips, enabling them to use less energy and radiate less heat.
	Probing dark matter with the Higgs boson Visible matter—everything from pollen to stars and galaxies—accounts for roughly 15% of the total mass of the universe. The remaining 85% is made of something entirely different from things we can touch and see: dark matter. Despite overwhelming evidence from the observation of gravitational effects, the nature of dark matter and its composition remain unknown.
	Elasticity key to plants and animals' ability to sting A new study explains for the very first time the principles behind the design of stings, needles, and spikes in animals and plants. The principles can be directly used in the development of new tools and medical equipment.
	Research reveals how material defects influence melting process In 1972, physicists J. Michael Kosterlitz and David Thouless published a groundbreaking theory of how phase changes could occur in two-dimensional materials. Experiments soon showed that the theory correctly captured the process of a helium film transitioning from a superfluid to a normal fluid, helping to usher in a new era of research on ultra-thin materials, not to mention earning Kosterlitz, a professor at Brown University, and Thouless shares of the 2016 Nobel Prize in Physics.
	Radiation pressure with recoil: Experimental proof for a 90 year-old theory Light exerts a certain amount of pressure onto a body: sun sails could thus power space probes in the future. However, when light particles (photons) hit an individual molecule and knock out an electron, the molecule flies toward the light source. Atomic physicists at Goethe University have now observed this for the first time, confirming a 90 year-old theory.
	Excitons form superfluid in certain 2-D combos Mixing and matching computational models of 2-D materials led scientists at Rice University to the realization that excitons—quasiparticles that exist when electrons and holes briefly bind—can be manipulated in new and useful ways.

Astronomy and Space news

	Research sheds new light on intelligent life existing across the galaxy Is there anyone out there? This is an age-old question that researchers have now shed new light on with a study that calculates there could be more than 30 intelligent civilizations throughout our Galaxy. This is an enormous advance over previous estimates which spanned from zero to billions.
	New lithium-rich Cepheid discovered in the Milky Way Italian astronomers have reported the discovery of a new lithium-rich galactic Cepheid star, identified by high-resolution spectroscopic observations. The newfound object, designated V363 Cas, is the fifth lithium-rich classical Cepheid in our Milky Way galaxy. The study detailing the finding was published June 5 on arXiv.org.
	Measuring the spin of a black hole A black hole, at least in our current understanding, is characterized by having "no hair," that is, it is so simple that it can be completely described by just three parameters, its mass, its spin and its electric charge. Even though it may have formed out of a complex mix of matter and energy, all other details are lost when the black hole forms. Its powerful gravitational field creates a surrounding surface, a "horizon," and anything that crosses that horizon (even light) cannot escape. Hence the singularity appears black, and any details about the infalling material are also lost and digested into the three knowable parameters.
	Electrically charged dust storms drive Martian chlorine cycle How's the weather on Mars? Tough on rovers, but very good for generating and moving highly reactive chlorine compounds. New research from Washington University in St. Louis planetary scientists shows that Martian dust storms, like the one that eventually shut down the Opportunity rover, drive the cycle of chlorine from surface to atmosphere and may shed light on the potential for finding life on Mars.
	Observatories around the solar system team up to study sun's influence At the heart of understanding our space environment is the knowledge that conditions throughout space—from the sun to the atmospheres of planets to the radiation environment in deep space—are connected.
	While stargazing on Mars, Curiosity rover spots Earth and Venus NASA's Curiosity Mars rover occasionally stops to stargaze. Recently, it captured a shot of Earth and Venus in the Red Planet's night sky.

Technology news

	Jitterbug: Roaches and robots shake it to transition between movements in tricky terrain Animals in their natural environments effortlessly switch up their movements to hunt, escape from predators and travel with their packs every day.
	Light bulb vibrations yield eavesdropping data In an era of digital eavesdropping where hackers employ a variety of means to take over built-in video cameras, peruse personal digital data and snoop on cellular conversations, researchers have finally seen the light.

	The first intuitive programming language for quantum computers Programming quantum computers is becoming easier: computer scientists at ETH Zurich have designed the first programming language that can be used to program quantum computers as simply, reliably and safely as classical computers. "Programming quantum computers is still a challenge for researchers," says Martin Vechev, computer science professor in ETH's Secure, Reliable and Intelligent Systems Lab (SRI), "which is why I'm so excited that we can now continue ETH Zurich's tradition in the development of quantum computers and programming languages."
