Published Researchers devise a new path toward 'quantum light'


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


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


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


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


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.
Published New method to control electron spin paves the way for efficient quantum computers


Researchers have developed a new method for manipulating information in quantum systems by controlling the spin of electrons in silicon quantum dots. The results provide a promising new mechanism for control of qubits, which could pave the way for the development of a practical, silicon-based quantum computer.
Published Will machine learning help us find extraterrestrial life?


Researchers have applied a deep learning technique to a previously studied dataset of nearby stars and uncovered eight previously unidentified signals of interest.
Published Qubits on strong stimulants



In the global push for practical quantum networks and quantum computers, an international team of researchers has demonstrated a leap in preserving the quantum coherence of quantum dot spin qubits.
Published Meteorites reveal likely origin of Earth's volatile chemicals


By analyzing meteorites, researchers have uncovered the likely far-flung origin of Earth's volatile chemicals, some of which form the building blocks of life.
Published Quantum physicists make major nanoscopic advance



In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
Published Solar System formed from 'poorly mixed cake batter,' isotope research shows


Earth's potassium arrived by meteoritic delivery service finds new research led by Earth and planetary scientists. Their work shows that some primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. These results can help elucidate the processes that shaped our Solar System and determined the composition of its planets.
Published Scientists observe 'quasiparticles' in classical systems


Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical system at room temperature: a two-dimensional crystal of particles driven by viscous flow in a microfluidic channel. Coupled by hydrodynamic forces, the particles form stable pairs -- a first example of classical quasiparticles, revealing deep links between quantum and classical dissipative systems.
Published Webb spies Chariklo ring system with high-precision technique


In an observational feat of high precision, scientists used a new technique with NASA's James Webb Space Telescope to capture the shadows of starlight cast by the thin rings of Chariklo. Chariklo is an icy, small body, but the largest of the known Centaur population, located more than 2 billion miles away beyond the orbit of Saturn.
Published No 'second law of entanglement' after all


When two microscopic systems are entangled, their properties are linked to each other irrespective of the physical distance between the two. Manipulating this uniquely quantum phenomenon is what allows for quantum cryptography, communication, and computation. While parallels have been drawn between quantum entanglement and the classical physics of heat, new research demonstrates the limits of this comparison. Entanglement is even richer than we have given it credit for.
Published How a 3 cm glass sphere could help scientists understand space weather


Space weather can interfere with spaceflight and the operation of satellites, but the phenomenon is very difficult to study on Earth because of the difference in gravity. Researchers effectively reproduced the type of gravity that exists on or near stars and other planets inside of a glass sphere measuring 3 centimeters in diameter, or about 1.2 inches. The achievement could help scientists overcome the limiting role of gravity in experiments that are intended to model conditions in stars and other planets.
Published Asteroid findings from specks of space dust could save the planet


New research into the durability and age of an ancient asteroid made of rocky rubble and dust, revealed significant findings that could contribute to potentially saving the planet if one ever hurtled toward Earth.
Published Darkest view ever of interstellar ice



Astronomers used observations from the James Webb Space Telescope (JWST) to achieve the darkest ever view of a dense interstellar cloud. These observations have revealed the composition of a virtual treasure chest of ices from the early universe, providing new insights into the chemical processes of one of the coldest, darkest places in the universe as well as the origins of the molecules that make up planetary atmospheres.
Published Shedding light on quantum photonics


As buzz grows ever louder over the future of quantum, researchers everywhere are working overtime to discover how best to unlock the promise of super-positioned, entangled, tunneling or otherwise ready-for-primetime quantum particles, the ability of which to occur in two states at once could vastly expand power and efficiency in many applications.
Published How was the solar system formed? The Ryugu asteroid is helping us learn



Our solar system is estimated to be about 4.57 billion years old. Previous analyses of ancient meteorites have shown that minerals were created through chemical reactions with water as far back as 4.5 billion years ago. New findings from the Ryugu asteroid samples indicate that carbonates were forming from water-rock reactions several million years earlier, even closer to the solar system's beginnings.
Published Tumultuous migration on the edge of the Hot Neptune Desert


A team reveals the eventful migration history of planets bordering the Hot Neptune Desert, these extrasolar planets that orbit very close to their star.
