Published Pass the salt: This space rock holds clues as to how Earth got its water
(via sciencedaily.com) Original source The discovery of tiny salt grains in a sample from an asteroid provides strong evidence that liquid water may be more common in the solar system than previously thought.
Published Flaring star could be down to young planet's disc inferno
(via sciencedaily.com) Original source New simulations offer new explanation for star's 85-year flare. In this scenario, a young giant planet is burning up very close to its star, suggesting solar systems may have hosted many of such planets that have since 'evaporated'.
Published Using photosynthesis for Martian occupation -- while making space travel more sustainable
(via sciencedaily.com) Original source Researchers are working on sustainable technology to harvest solar power in space -- which could supplement life support systems on the Moon and Mars.
Published 'Hot Jupiters' may not be orbiting alone
(via sciencedaily.com) Original source Astronomers challenge longstanding beliefs about the isolation of 'hot Jupiters' and proposes a new mechanism for understanding the exoplanets' evolution.
Published Breakthrough: Scientists develop artificial molecules that behave like real ones
(via sciencedaily.com) Original source Scientists have developed synthetic molecules that resemble real organic molecules. A collaboration of researcher can now simulate the behavior of real molecules by using artificial molecules.
Published Schrödinger's cat makes better qubits
(via sciencedaily.com) Original source Drawing from Schrodinger's cat thought experiment, scientists have built a 'critical cat code' qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs.
Published Long missions, frequent travel take a toll on astronauts' brains
(via sciencedaily.com) Original source A study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset.
Published New study identifies mechanism driving the sun's fast wind
(via sciencedaily.com) Original source Researchers used data from NASA's Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of 1 million miles per hour. They discovered that the energy released from the magnetic field near the sun's surface is powerful enough to drive the fast solar wind, which is made up of ionized particles -- called plasma -- that flow outward from the sun.
Published New superconducting diode could improve performance of quantum computers and artificial intelligence
(via sciencedaily.com) Original source A team has developed a more energy-efficient, tunable superconducting diode -- a promising component for future electronic devices -- that could help scale up quantum computers for industry and improve artificial intelligence systems.
Published Proposed design could double the efficiency of lightweight solar cells for space-based applications
(via sciencedaily.com) Original source When it comes to supplying energy for space exploration and settlements, commonly available solar cells made of silicon or gallium arsenide are still too heavy to be feasibly transported by rocket. To address this challenge, a wide variety of lightweight alternatives are being explored, including solar cells made of a thin layer of molybdenum selenide, which fall into the broader category of 2D transition metal dichalcogenide (2D TMDC) solar cells. Researchers propose a device design that can take the efficiencies of 2D TMDC devices from 5%, as has already been demonstrated, to 12%.
Published Researchers demonstrate secure information transfer using spatial correlations in quantum entangled beams of light
(via sciencedaily.com) Original source Researchers have demonstrated the principle of using spatial correlations in quantum entangled beams of light to encode information and enable its secure transmission.
Published Webb Space Telescope detects universe's most distant complex organic molecules
(via sciencedaily.com) Original source Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth -- the most distant galaxy in which these molecules are now known to exist. Thanks to the capabilities of the recently launched James Webb Space Telescope and careful analyses from the research team, a new study lends critical insight into the complex chemical interactions that occur in the first galaxies in the early universe.
Published Supercomputer simulations provide a better picture of the Sun's magnetic field
(via sciencedaily.com) Original source The new findings challenge the conventional understanding of solar dynamics and could improve predictions of solar weather in the future.
Published The 'breath' between atoms -- a new building block for quantum technology
(via sciencedaily.com) Original source Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.
Published Understanding the tantalizing benefits of tantalum for improved quantum processors
(via sciencedaily.com) Original source Researchers working to improve the performance of superconducting qubits, the foundation of quantum computers, have been experimenting using different base materials in an effort to increase the coherent lifetimes of qubits. The coherence time is a measure of how long a qubit retains quantum information, and thus a primary measure of performance. Recently, scientists discovered that using tantalum in superconducting qubits makes them perform better, but no one has been able to determine why -- until now.
Published First X-ray of a single atom
(via sciencedaily.com) Original source Scientists have taken the world's first X-ray SIGNAL (or SIGNATURE) of just one atom. This groundbreaking achievement could revolutionize the way scientists detect the materials.
Published Towering plume of water escaping from Saturn moon
(via sciencedaily.com) Original source Scientists have observed a towering plume of water vapor more than 6,000 miles long -- roughly the distance from the U.S. to Japan -- spewing from the surface of Saturn's moon, Enceladus.
Published Symmetry breaking by ultrashort light pulses opens new quantum pathways for coherent phonons
(via sciencedaily.com) Original source Researchers have demonstrated a novel concept for exciting and probing coherent phonons in crystals of a transiently broken symmetry. The key of this concept lies in reducing the symmetry of a crystal by appropriate optical excitation, as has been shown with the prototypical crystalline semimetal bismuth (Bi).
Published One-third of galaxy's most common planets could be in habitable zone
(via sciencedaily.com) Original source A third of the exoplanets orbiting common M dwarf stars have gentle enough orbits to potentially be in the habitable zone capable of hosting liquid water.
Published Forging a dream material with semiconductor quantum dots
(via sciencedaily.com) Original source Researchers have succeeded in creating a 'superlattice' of semiconductor quantum dots that can behave like a metal, potentially imparting exciting new properties to this popular class of materials.
