Published Securing supply chains with quantum computing
(via sciencedaily.com) New research in quantum computing is moving science closer to being able to overcome supply-chain challenges and restore global security during future periods of unrest.
Published When the light is neither 'on' nor 'off' in the nanoworld
(via sciencedaily.com) Scientists detect the quantum properties of collective optical-electronic oscillations on the nanoscale. The results could contribute to the development of novel computer chips.
Published Four classes of planetary systems
(via sciencedaily.com) Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers have now shown that there are in fact four types of planetary systems.
Published Upsurge in rocket launches could impact the ozone layer
(via sciencedaily.com) Researchers have summarized the threats that future rocket launches would pose to Earth's protective ozone layer.
Published Researchers detail never-before-seen properties in a family of superconducting Kagome metals
(via sciencedaily.com) Researchers have used an innovative new strategy combining nuclear magnetic resonance imaging and a quantum modeling theory to describe the microscopic structure of Kagome superconductor RbV3Sb5 at 103 degrees Kelvin, which is equivalent to about 275 degrees below 0 degrees Fahrenheit.
Published Scientists boost quantum signals while reducing noise
(via sciencedaily.com) Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.
Published Hubble captures the start of a new spoke season at Saturn
(via sciencedaily.com) Since their discovery by NASA's Voyager mission in the 1980s, temporary 'spoke' features across Saturn's rings have fascinated scientists, yet eluded explanation. They have been observed in the years preceding and following the planet's equinox, becoming more prominent as the date approaches. Saturn's upcoming autumnal equinox of the northern hemisphere on May 6, 2025, means that spoke season has come again. NASA's Hubble Space Telescope will be on the job studying the spokes, thanks to time dedicated to Saturn in the mission's ongoing Outer Planet Atmospheres Legacy (OPAL) program. Are the smudgy features related to Saturn's magnetic field and its interaction with the solar wind, as prevailing theory suggests? Confirmation could come in this spoke season, as scientists combine archival data from NASA's Cassini mission with new Hubble observations.
Published Space dust as Earth's sun shield
(via sciencedaily.com) Dust launched from the moon's surface or from a space station positioned between Earth and the sun could reduce enough solar radiation to mitigate the impacts of climate change.
Published Distortion-free forms of structured light
(via sciencedaily.com) Research offers a new approach to studying complex light in complex systems, such as transporting classical and quantum light through optical fiber, underwater channels, living tissue and other highly aberrated systems.
Published Spanish lagoon used to better understand wet-to-dry transition of Mars
(via sciencedaily.com) In the ongoing search for signs of life on Mars, a new study proposes focusing on 'time-resolved analogs' -- dynamic and similar Earth environments where changes can be analyzed over many years.
Published Scientists make major breakthrough in developing practical quantum computers that can solve big challenges of our time
(via sciencedaily.com) Researchers have demonstrated that quantum bits (qubits) can directly transfer between quantum computer microchips and demonstrated this with record-breaking connection speed and accuracy. This breakthrough resolves a major challenge in building quantum computers large and powerful enough to tackle complex problems that are of critical importance to society.
Published A new ring system discovered in our Solar System
(via sciencedaily.com) Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into question current theories of how ring systems are formed.
Published New models explain canyons on Pluto moon
(via sciencedaily.com) In 2015, when NASA's New Horizons spacecraft encountered the Pluto-Charon system, scientists discovered interesting, geologically active objects instead of the inert icy orbs previously envisioned. Scientists have revisited the data to explore the source of cryovolcanic flows and an obvious belt of fractures on Pluto's large moon Charon. These new models suggest that when the moon's internal ocean froze, it may have formed the deep, elongated depressions along its girth but was less likely to lead to cryovolcanoes erupting with ice, water and other materials in its northern hemisphere.
Published Entangled atoms cross quantum network from one lab to another
(via sciencedaily.com) Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.
Published Hubble directly measures mass of a lone white dwarf
(via sciencedaily.com) Astronomers have directly measured the mass of a single, isolated white dwarf -- the surviving core of a burned-out, Sun-like star. Researchers found that the white dwarf is 56 percent the mass of our Sun. This agrees with earlier theoretical predictions of the white dwarf's mass and corroborates current theories of how white dwarfs evolve as the end product of a typical star's evolution. The unique observation yields insights into theories of the structure and composition of white dwarfs.
Published Researchers devise a new path toward 'quantum light'
(via sciencedaily.com) Researchers have theorized a new mechanism to generate high-energy 'quantum light', which could be used to investigate new properties of matter at the atomic scale.
Published Thin, lightweight layer provides radiation barrier for perovskites in space, protection from elements on Earth
(via sciencedaily.com) An ultrathin protective coating proves sufficient to protect a perovskite solar cell from the harmful effects of space and harden it against environmental factors on Earth, according to newly published research.
Published Researchers take a step toward novel quantum simulators
(via sciencedaily.com) If scaled up successfully, the team's new system could help answer questions about certain kinds of superconductors and other unusual states of matter.
Published Researchers complete first real-world study of Martian helicopter dust dynamics
(via sciencedaily.com) Researchers have completed the first real-world study of Martian dust dynamics based on Ingenuity's historic first flights on the Red Planet, paving the way for future extraterrestrial rotorcraft missions. The work could support NASA's Mars Sample Return Program, which will retrieve samples collected by Perseverance, or the Dragonfly mission that will set course for Titan, Saturn's largest moon, in 2027.
Published Evidence that Saturn's moon Mimas is a stealth ocean world
(via sciencedaily.com) When a scientist discovered surprising evidence that Saturn's smallest, innermost moon could generate the right amount of heat to support a liquid internal ocean, colleagues began studying Mimas' surface to understand how its interior may have evolved. Numerical simulations of the moon's Herschel impact basin, the most striking feature on its heavily cratered surface, determined that the basin's structure and the lack of tectonics on Mimas are compatible with a thinning ice shell and geologically young ocean.
