Physics news

	Improved Primakoff-type experiment gives improved accuracy of pion measurement A large international team of researchers has improved upon Primakoff-type experiments to give an improved accuracy of pion measurement. In their paper published in the journal Science, the group gives an overview of their objectives and outline the experiments they conducted to achieve higher accuracy when measuring the decay of a pion into two photons. Harvey Meyer, with the University of Mainz provides a timeline of the history of quantum chromodynamics theory and also gives an overview of the work done by the researchers in this new effort, in the same journal issue.
	In search of the lighting material of the future At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale—that means it is practically made for use in large-area room lighting. Researchers have been searching for such materials for a long time. The newly generated understanding will facilitate the rapid and cost-efficient development of new lighting appliances in the future. The study appears today in the journal Nature Communications.
	Looking for dark matter with the Universe's coldest material Scientists have been able to observe the universe and determine that about 80% of the its mass appears to be "dark matter," which exerts a gravitational pull but does not interact with light, and thus can't be seen with telescopes. Our current understanding of cosmology and nuclear physics suggests that dark matter could be made of axions, hypothetical particles with unusual symmetry properties.
	First direct look at how light excites electrons to kick off a chemical reaction The first step in many light-driven chemical reactions, like the ones that power photosynthesis and human vision, is a shift in the arrangement of a molecule's electrons as they absorb the light's energy. This subtle rearrangement paves the way for everything that follows and determines how the reaction proceeds.
	Researchers see path to quantum computing at room temperature Army researchers predict quantum computer circuits that will no longer need extremely cold temperatures to function could become a reality after about a decade.

Astronomy and Space news

	Researchers establish new timeline for ancient magnetic field on Mars Mars had a global magnetic field much earlier—and much later—in the planet's history than scientists have previously known.
	Research reveals possibly active tectonic system on the Moon Researchers have discovered a system of ridges spread across the nearside of the Moon topped with freshly exposed boulders. The ridges could be evidence of active lunar tectonic processes, the researchers say, possibly the echo of a long-ago impact that nearly tore the Moon apart.
	Researchers find space station's surface microbial profile resembles skin of its crew members A study conducted by a team of national laboratory and NASA researchers has found that the environment of the International Space Station is affected by the microbial composition of the astronauts themselves.

	Virgin Galactic completes first glide flight in New Mexico Virgin Galactic's spaceship VSS Unity landed in the New Mexico desert on Friday, marking its first glide flight from Spaceport America as the company moves toward commercial operations.
	NASA goes private for 1st astronaut lunar landers in decades NASA is turning to private industry for the first lunar landers for astronauts in a half-century, with three competing, quite contrasting versions.
	Earth flyby opens new science opportunities for BepiColombo Science instruments aboard the European-Japanese Mercury explorer BepiColombo are in excellent condition to gather high-quality data during the spacecraft's long cruise to the innermost planet of the Solar System despite not having been designed for this purpose, teams collaborating on the mission learned during the spacecraft's April flyby of Earth.
	Hubble's impactful life alongside space debris During its 30 years in orbit around Earth, the NASA/ESA Hubble Space Telescope has witnessed the changing nature of spaceflight as the skies have filled with greater numbers of satellites, the International Space Station was born and in-space crashes and explosions have created clouds of fast-moving space debris.
	Asteroid grazes path of satellites in geostationary ring A reasonably small 4-8 m asteroid recently flew by Earth, passing close to satellites orbiting in the geostationary ring at a distance of about 42 735 km from Earth's centre and only about 1200 km from the nearest satellite.
	NASA begs spectators for astronaut launch: Please stay home! NASA and SpaceX on Friday urged spectators to stay home for the first home launch of astronauts in nearly a decade because of the coronavirus pandemic.
	How could an explosive Big Bang be the birth of our universe? How can a Big Bang have been the start of the universe, since intense explosions destroy everything? – Tristan S., age 8, Newark, Delaware

Technology news

	A system to reproduce different animal locomotion skills in robots Researchers at Google Research and the University of California, Berkeley, have recently developed an imitation learning system that could enable a variety of agile locomotion behaviors in robots. Their technique, presented in a paper pre-published on arXiv, allows robots to acquire new skills by imitating animals.
	A 3-D memristor-based circuit for brain-inspired computing Researchers at the University of Massachusetts and the Air Force Research Laboratory Information Directorate have recently created a 3-D computing circuit that could be used to map and implement complex machine learning algorithms, such convolutional neural networks (CNNs). This 3-D circuit, presented in a paper published in Nature Electronics, comprises eight layers of memristors; electrical components that regulate the electrical current flowing in a circuit and directly implement neural network weights in hardware.
	Raspberry Pi unveils $50 interchangeable-lens camera board Raspberry Pi's new high quality camera doesn't sport a fancy name—it's actually called "High Quality Camera"—but it packs some new features do-it-yourselfers are sure to enjoy, and it's being offered at Raspberry's typical bargain-basement prices.
