Published Switching 'spin' on and off (and up and down) in quantum materials at room temperature
(via sciencedaily.com) Researchers have found a way to control the interaction of light and quantum 'spin' in organic semiconductors, that works even at room temperature.
Published Using supernovae to study neutrinos' strange properties
(via sciencedaily.com) In a new study, researchers have taken an important step toward understanding how exploding stars can help reveal how neutrinos, mysterious subatomic particles, secretly interact with themselves.
Published Carbon-based quantum technology
(via sciencedaily.com) Graphene nanoribbons have outstanding properties that can be precisely controlled. Researchers have succeeded in attaching electrodes to individual atomically precise nanoribbons, paving the way for precise characterization of the fascinating ribbons and their possible use in quantum technology.
Published Researchers develop a unique quantum mechanical approach to determining metal ductility
(via sciencedaily.com) A team of scientists developed a new quantum-mechanics-based approach to predict metal ductility. The team demonstrated its effectiveness on refractory multi-principal-element alloys.
Published Hundred-year storms? That's how long they last on Saturn
(via sciencedaily.com) Megastorms regularly appear on Saturn, marring the relatively bland surface before disappearing. But radio observations show that the storms have long-lasting effects deeper in the atmosphere, in particular in the distribution of ammonia. Using NRAO's Very Large Array, astronomers see such impacts from storms that happened hundreds of years ago. The findings will help explain the differences between storms on the gas giants Saturn and Jupiter.
Published Arrays of quantum rods could enhance TVs or virtual reality devices
(via sciencedaily.com) Using scaffolds of folded DNA, engineers assembled arrays of quantum rods with desirable photonic properties that could enable them to be used as highly efficient micro-LEDs for televisions or virtual reality devices.
Published Could artificially dimming the sun prevent ice melt?
(via sciencedaily.com) Original source With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ice sheet by artificially 'dimming the sun'. The results show that artificial influence does not work without decarbonization and entails high risks.
Published After seventeen years, a spacecraft makes its first visit home
(via sciencedaily.com) On Aug. 12, 2023, NASA's STEREO-A spacecraft will pass between the Sun and Earth, marking the first Earth flyby of the nearly 17-year-old mission. The visit home brings a special chance for the spacecraft to collaborate with NASA missions near Earth and reveal new insights into our closest star.
Published Potential application of unwanted electronic noise in semiconductors
(via sciencedaily.com) Random telegraph noise (RTN) in semiconductors is typically caused by two-state defects. Two-dimensional (2D) van der Waals (vdW) layered magnetic materials are expected to exhibit large fluctuations due to long-range Coulomb interaction; importantly, which could be controlled by a voltage compared to 3D counterparts having large charge screening. Researchers reported electrically tunable magnetic fluctuations and RTN signal in multilayered vanadium-doped tungsten diselenide (WSe2) by using vertical magnetic tunneling junction devices. They identified bistable magnetic states in the 1/f2 RTNs in noise spectroscopy, which can be further utilized for switching devices via voltage polarity.
Published Possible seasonal climate patterns on early Mars
(via sciencedaily.com) Original source New observations of mud cracks made by the Curiosity Rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments, indicating that the red planet may have once seen seasonal weather patterns or even flash floods.
Published Webb reveals colors of Earendel, most distant star ever detected
(via sciencedaily.com) NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang. Webb's NIRCam (Near-Infrared Camera) instrument reveals the star to be a massive B-type star more than twice as hot as our Sun, and about a million times more luminous.
Published Physicists demonstrate how sound can be transmitted through vacuum
(via sciencedaily.com) Original source A classic movie was once promoted with the punchline: 'In space, no one can hear you scream'. Physicists have now demonstrated, to the contrary, that in certain situations sound can be transmitted strongly across a vacuum region!
Published Chemical contamination on International Space Station is out of this world
(via sciencedaily.com) Original source Concentrations of potentially harmful chemical compounds in dust collected from air filtration systems on the International Space Station (ISS) exceed those found in floor dust from many American homes, a new study reveals.
Published Researchers use SPAD detector to achieve 3D quantum ghost imaging
(via sciencedaily.com) Researchers have reported the first 3D measurements acquired with quantum ghost imaging. The new technique enables 3D imaging on a single photon level, yielding the lowest photon dose possible for any measurement.
Published Quantum material exhibits 'non-local' behavior that mimics brain function
(via sciencedaily.com) New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.
Published Geomagnetic field protects Earth from electron showers
(via sciencedaily.com) Original source Geophysicists studied the activity of high energy electrons and clarified the unexpected protective role of the geomagnetic field surrounding the Earth.
Published Gas streamers feed triple baby stars
(via sciencedaily.com) Original source New observations and simulations of three spiral arms of gas feeding material to three protostars forming in a trinary system have clarified the formation of multi-star systems.
Published Scientists discover the highest-energy light coming from the sun
(via sciencedaily.com) New research details the discovery of the highest-energy light ever observed from the sun. The international team behind the discovery also found that this type of light, known as gamma rays, is surprisingly bright. That is, there's more of it than scientists had previously anticipated.
Published Study examines Earth and Mars to determine how climate change affects the paths of rivers
(via sciencedaily.com) Original source The study investigated why the paths of meandering rivers change over time and is a step toward understanding what the hydroclimate on Mars was like when there was still surface water.
Published New exoplanet discovery builds better understanding of planet formation
(via sciencedaily.com) An international team of scientists have discovered an unusual Jupiter-sized planet orbiting a low-mass star called TOI-4860, located in the Corvus constellation.
