Published Ultrafast laser pulses could lessen data storage energy needs



A discovery from an experiment with magnetic materials and ultrafast lasers could be a boon to energy-efficient data storage.
Published A non-proliferation solution: Using antineutrinos to surveil nuclear reactors



Antineutrinos generated in nuclear fission can be measured to remotely monitor the operation of nuclear reactors and verify that they are not being used to produce nuclear weapons, report scientists. Thanks to a newly developed method, it is now possible to estimate a reactor's operation status, fuel burnup, and fuel composition based entirely on its antineutrino emissions. This technique could contribute massively to nuclear non-proliferation efforts and, in turn, safer nuclear energy.
Published Long live the graphene valley state



Researchers found evidence that bilayer graphene quantum dots may host a promising new type of quantum bit based on so-called valley states.
Published Study delivers detailed photos of galaxies' inner structures



High-resolution images captured by the James Webb Space Telescope are offering powerful insights into the complex dust patterns of nearby star-forming galaxies.
Published Space solar power project ends first in-space mission with successes and lessons



A 10-month mission demonstrated three elements of the plan to beam solar power from space to Earth.
Published The surface knows what lies beneath: Physicists show how to detect higher-order topological insulators



Just like a book can't be judged by its cover, a material can't always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface previously thought to be 'featureless' holds an unmistakable signature that could lead to the first definitive observation.
Published Astronomers produce most sensitive radio image ever of ancient star cluster



Astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly-packed stars.
Published Discovery changes understanding of water's history on the Moon



New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held understanding.
Published Physicists identify overlooked uncertainty in real-world experiments



The rules of statistical physics address the uncertainty about the state of a system that arises when that system interacts with its environment. But they've long missed another kind. In a new paper, researchers argue that uncertainty in the thermodynamic parameters themselves -- built into equations that govern the energetic behavior of the system -- may also influence the outcome of an experiment.
Published Solid-state qubits: Forget about being clean, embrace mess



New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits, a new paper shows.
Published Research sheds new light on Moon rock formation solving major puzzle in lunar geology



New research has cracked a vital process in the creation of a unique rock type from the Moon. The discovery explains its signature composition and very presence on the lunar surface at all, unraveling a mystery which has long-eluded scientists.
Published Earth-sized planet discovered in 'our solar backyard'



Astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It's a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve.
Published NASA scientists discover a novel galactic 'fossil'



Researchers at NASA's Goddard Space Flight Center have discovered X-ray activity that sheds light on the evolution of galaxies.
Published Our surprising magnetic galaxy



A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms of our galaxy break away from this general picture significantly and are tilted away from the galactic average by a high degree. The findings suggest magnetic fields strongly impact star-forming regions which means they played a part in the creation of our own solar system.
Published Surprise gamma-ray feature beyond our galaxy



Astronomers analyzing 13 years of data from NASA's Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy.
Published Bridging light and electrons



Researchers have merged nonlinear optics with electron microscopy, unlocking new capabilities in material studies and the control of electron beams.
Published Molecularly designing polymer networks to control sound damping



The world is filled with a myriad of sounds and vibrations -- the gentle tones of a piano drifting down the hall, the relaxing purr of a cat laying on your chest, the annoying hum of the office lights. Imagine being able to selectively tune out noises of a certain frequency. Researchers have now synthesized polymer networks with two distinct architectures and crosslink points capable of dynamically exchanging polymer strands to understand how the network connectivity and bond exchange mechanisms govern the overall damping behavior of the network. The incorporation of dynamic bonds into the polymer network demonstrates excellent damping of sound and vibrations at well-defined frequencies.
Published Astronomers make rare exoplanet discovery, and a giant leap in detecting Earth-like bodies



Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion -- shedding light on the formation of planets like Earth.
Published Potential solvents identified for building on moon and Mars



Researchers have taken the first steps toward finding liquid solvents that may someday help extract critical building materials from lunar and Martian-rock dust, an important piece in making long-term space travel possible. Using machine learning and computational modeling, researchers have found about half a dozen good candidates for solvents that can extract materials on the moon and Mars usable in 3D printing. The powerful solvents, called ionic liquids, are salts that are in a liquid state.
Published Revolutionizing real-time data processing with edge computing and reservoir technology



Traditional cloud computing faces various challenges when processing large amounts of data in real time. 'Edge' computing is a promising alternative and can benefit from devices known as physical reservoirs. Researchers have now developed a novel memristor device for this purpose. It responds to electrical and optical signals and overcomes real-time processing limitations. When tested, it achieved up to 90.2% accuracy in digit identification, demonstrating its potential for applications in artificial intelligence systems and beyond.
