Published Intriguing nearby world sized between Earth, Venus
(via sciencedaily.com) Original source Astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away.
Published Planet hunters unveil massive catalog of strange worlds
(via sciencedaily.com) Original source While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar system.
Published Shedding light on the chemical enigma of sulfur trioxide in the atmosphere
(via sciencedaily.com) Original source Researchers discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric anhydride products are almost certainly key contributors to atmospheric new particle formation and a way to efficiently incorporate carboxylic acids into atmospheric nanoparticles. Better prediction of aerosol formation can help curb air pollution and reduce uncertainties concerning climate change.
Published First pictures from Euclid satellite reveal billions of orphan stars
(via sciencedaily.com) Original source The first scientific pictures from the Euclid satellite mission have revealed more than 1,500 billion orphan stars scattered throughout the Perseus cluster of galaxies.
Published Potentially habitable 'exo-Venus' with Earth-like temperature discovered
(via sciencedaily.com) Original source Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.
Published New discoveries about the nature of light could improve methods for heating fusion plasma
(via sciencedaily.com) Original source Scientists have made discoveries about light particles known as photons that could aid the quest for fusion energy.
Published The origin of the sun's magnetic field could lie close to its surface
(via sciencedaily.com) Original source Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's outermost layers. If confirmed, the findings could help scientists better predict space weather.
Published Strings that can vibrate forever (kind of)
(via sciencedaily.com) Original source Researchers have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object -- approaching what is currently only achievable near absolute zero temperatures. Their study pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors.
Published Ethylene from CO2: Building-kit catalyst
(via sciencedaily.com) Original source Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary chemical raw material, from CO2. Nitrogen atoms with a particular electron configuration play a critical role for the catalyst.
Published New crystal production method could enhance quantum computers and electronics
(via sciencedaily.com) Original source Scientists describe a new method to make very thin crystals of the element bismuth -- a process that may aid the manufacturing of cheap flexible electronics an everyday reality.
Published Enhancing superconductivity of graphene-calcium superconductors
(via sciencedaily.com) Original source Researchers experimentally investigate the impact of introducing high-density calcium on the superconductivity of calcium-intercalated bilayer graphene.
Published Webb Telescope offers first glimpse of an exoplanet's interior
(via sciencedaily.com) Original source A surprisingly low amount of methane and a super-sized core hide within the cotton candy -- like planet WASP-107 b.
Published Ion irradiation offers promise for 2D material probing
(via sciencedaily.com) Original source Two-dimensional materials such as graphene promise to form the basis of incredibly small and fast technologies, but this requires a detailed understanding of their electronic properties. New research demonstrates that fast electronic processes can be probed by irradiating the materials with ions first.
Published Magnetic imprint on deconfined nuclear matter
(via sciencedaily.com) Original source Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study provides proof that the magnetic fields exist and offers a new way to measure electrical conductivity in quark-gluon plasma.
Published Diamond glitter: A play of colors with artificial DNA crystals
(via sciencedaily.com) Original source Using DNA origami, researchers have built a diamond lattice with a periodicity of hundreds of nanometers -- a new approach for manufacturing semiconductors for visible light.
Published Scientists use generative AI to answer complex questions in physics
(via sciencedaily.com) Original source Researchers used generative AI to develop a physics-informed technique to classify phase transitions in materials or physical systems that is much more efficient than existing machine-learning approaches.
Published Shedding light on perovskite hydrides using a new deposition technique
(via sciencedaily.com) Original source Perovskite hydrides are promising materials for various emerging energy technologies, but measuring their intrinsic hydride-ion conductivity is difficult. In a recent study, researchers address this issue using a novel laser deposition technique in an H-radical atmosphere. Using this approach, they grew thin-film single crystals of two different perovskite hydrides and characterized their hydride-ion conductivity. These efforts will bolster research on hydrogen-related materials.
Published Hubble views the dawn of a sun-like star
(via sciencedaily.com) Original source Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.

(via sciencedaily.com) Original source SuperLimbs, a system of wearable robotic limbs, can physically support an astronaut and lift them back on their feet after a fall, helping them conserve energy for other essential tasks.
Published Detection of an Earth-sized exoplanet orbiting the ultracool dwarf star SPECULOOS-3
(via sciencedaily.com) Original source Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second planetary system discovered around this type of star.
