Published Study shedding new light on Earth's global carbon cycle could help assess liveability of other planets
(via sciencedaily.com) Original source Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth -- and it could help assess which other planets can develop life, ranging from plants to animals and humans.
Published New technique lets scientists create resistance-free electron channels
(via sciencedaily.com) Original source A team has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state -- an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics.
Published Will the convergence of light and matter in Janus particles transcend performance limitations in the optical display industry?
(via sciencedaily.com) Original source Team successfully exerted electrical control over polaritons, hybridized light-matter particles, at room temperature.
Published Inexplicable flying fox found in Hydra galaxy cluster
(via sciencedaily.com) Original source High sensitivity radio observations have discovered a cloud of magnetized plasma in the Hydra galaxy cluster. The odd location and shape of this plasma defy all conventional explanations. Dubbed the Flying Fox based on its silhouette, this plasma will remain a mystery until additional observations can provide more insight.
Published Chemical reactions can scramble quantum information as well as black holes
(via sciencedaily.com) Original source A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.
Published Neutron stars are key to understanding elusive dark matter
(via sciencedaily.com) Original source Scientists may be one step closer to unlocking one of the great mysteries of the universe after calculating that neutron stars might hold a key to helping us understand elusive dark matter.
Published Astronomy: How do brown dwarfs form?
(via sciencedaily.com) Original source New observations provide insights into whether the birth of the giant planets takes a similar course to that of stars.
Published CHEOPS detects a 'rainbow' on an exoplanet
(via sciencedaily.com) Original source The CHEOPS space telescope is providing new information on the mysterious exoplanet WASP-76b. This ultra-hot giant is characterized by an asymmetry between the amount of light observed on its eastern terminator -- the fictitious line that separates its night side from its day side -- and that observed on its western terminator. This peculiarity is thought to be due to a 'glory', a luminous phenomenon similar to a rainbow, which occurs if the light from the star -- the 'sun' around which the exoplanet orbits -- is reflected by clouds made up of a perfectly uniform substance. If this hypothesis is confirmed, this would be the first detection of this phenomenon outside our solar system.
Published Stellar collisions produce strange, zombie-like survivors
(via sciencedaily.com) Original source Densely packed, fast-moving stars at the Milky Way's center can collide with each other. New research uses simulations to explore the outcomes of these collisions. Some collisions are more like 'violent high fives' while others are full-on mergers.
Published First results from DESI make the most precise measurement of our expanding universe
(via sciencedaily.com) Original source Researchers have used the Dark Energy Spectroscopic Instrument to make the largest 3D map of our universe and world-leading measurements of dark energy, the mysterious cause of its accelerating expansion.
Published Progress in quantum physics: Researchers tame superconductors
(via sciencedaily.com) Original source An international team including researchers from the University of W rzburg has succeeded in creating a special state of superconductivity. This discovery could advance the development of quantum computers.
Published NASA's Webb probes an extreme starburst galaxy
(via sciencedaily.com) Original source A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.
Published Researchers discover 'neutronic molecules'
(via sciencedaily.com) Original source Researchers have discovered 'neutronic' molecules, in which neutrons can be made to cling to quantum dots, held just by the strong force. The finding may lead to new tools for probing material properties at the quantum level and exploring new kinds of quantum information processing devices.
Published Researchers visualize quantum effects in electron waves
(via sciencedaily.com) Original source One of the most fundamental interactions in physics is that of electrons and light. In an experiment, scientists have now managed to observe what is known as the Kapitza-Dirac effect for the first time in full temporal resolution. This effect was first postulated over 90 years ago, but only now are its finest details coming to light.
Published First results from BREAD experiment demonstrate a new approach to searching for dark matter
(via sciencedaily.com) Original source One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it s no minor thing currently, scientists think it makes up about 85% of all the mass in the universe.
Published Sunrise to sunset, new window coating blocks heat -- not view
(via sciencedaily.com) Original source Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun's angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.
Published 100 kilometers of quantum-encrypted transfer
(via sciencedaily.com) Original source Researchers have taken a big step towards securing information against hacking. They have succeeded in using quantum encryption to securely transfer information 100 kilometers via fiber optic cable -- roughly equivalent to the distance between Oxford and London.
Published Researchers discover dual topological phases in an intrinsic monolayer crystal
(via sciencedaily.com) Original source An international team working with single-atom thick crystals found TaIrTe4's transition between the two distinct topological states of insulation and conduction. The material exhibited zero electrical conductivity within its interior, while its boundaries remain conductive. The team's investigation determined that the two topological states stem from disparate origins. The novel properties can serve as a promising platform for exploring exotic quantum phases and electromagnetism.
Published Magnetic avalanche triggered by quantum effects
(via sciencedaily.com) Original source Scientists have shown that Barkhausen noise can be produced not only through traditional, or classical means, but through quantum mechanical effects. The research represents an advance in fundamental physics and could one day have applications in creating quantum sensors and other electronic devices.
