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 DESI early data release holds nearly two million objects
(via sciencedaily.com) Original source The first batch of data from the Dark Energy Spectroscopic Instrument is now available for researchers to explore. Taken during the experiment's 'survey validation' phase, the data include distant galaxies and quasars as well as stars in our own Milky Way.
Published Four-legged robot traverses tricky terrains thanks to improved 3D vision
(via sciencedaily.com) Original source Researchers have developed a new model that trains four-legged robots to see more clearly in 3D. The advance enabled a robot to autonomously cross challenging terrain with ease -- including stairs, rocky ground and gap-filled paths -- while clearing obstacles in its way.
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 A new Tatooine-like multi-planetary system identified
(via sciencedaily.com) Original source An international team of astronomers has announced the second-ever discovery of a multiplanetary circumbinary system.
Published Mori3: A polygon shape-shifting robot for space travel
(via sciencedaily.com) Original source By combining inspiration from the digital world of polygon meshing and the biological world of swarm behavior, the Mori3 robot can morph from 2D triangles into almost any 3D object. The research shows the promise of modular robotics for space travel.
Published Astronomers discover supernova explosion through rare 'cosmic magnifying glasses'
(via sciencedaily.com) Original source An international team of scientists recently discovered an exceptionally rare gravitationally lensed supernova, which the team named 'SN Zwicky.' Located more than 4 billion light years away, the supernova was magnified nearly 25 times by a foreground galaxy acting as a lens. The discovery presents a unique opportunity for astronomers to learn more about the inner cores of galaxies, dark matter and the mechanics behind universe expansion.
Published Novel ferroelectrics for more efficient microelectronics
(via sciencedaily.com) Original source A team of researchers is exploring novel materials that have potential to make microelectronics more energy efficient. Their recent work explores recently discovered wurtzite ferroelectrics, which are mainly composed of materials that are already incorporated in semiconductor technology for integrated circuits. These materials allow for the integration of new power-efficient devices for applications such as non-volatile memory, electro-optics, and energy harvesting.
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 MethaneMapper is poised to solve the problem of underreported methane emissions
(via sciencedaily.com) Original source MethaneMapper is an artificial intelligence-powered hyperspectral imaging tool that researchers have developed to detect real-time methane emissions and trace them to their sources. The tool works by processing hyperspectral data gathered during overhead, airborne scans of the target area.
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 Elusive planets play 'hide and seek' with CHEOPS
(via sciencedaily.com) Original source Astronomers have clearly identified the existence of four new exoplanets. The four mini-Neptunes are smaller and cooler, and more difficult to find than the so-called Hot Jupiter exoplanets which have been found in abundance.
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 What made the brightest cosmic explosion of all time so exceptional?
(via sciencedaily.com) Original source Last year, telescopes around the world registered the brightest cosmic explosion of all time. Astrophysicists can now explain what made it so dazzling.
Published AI-generated academic science writing can be identified with over 99% accuracy
(via sciencedaily.com) Original source The debut of artificial intelligence chatbot ChatGPT has set the world abuzz with its ability to churn out human-like text and conversations. Still, many telltale signs can help us distinguish AI chatbots from humans, according to a new study. Based on the signs, the researchers developed a tool to identify AI-generated academic science writing with over 99% accuracy.
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 Not your average space explosion: Very long baseline array finds classical novae are anything but simple
(via sciencedaily.com) Original source While studying classical novae using the National Radio Astronomy Observatory's Very Long Baseline Array (VLBA), a graduate researcher uncovered evidence the objects may have been erroneously typecast as simple. The new observations detected non-thermal emission from a classical nova with a dwarf companion.
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 First detection of secondary supermassive black hole in a well-known binary system
(via sciencedaily.com) Original source An international team of astronomers observed the second one of the two supermassive black holes circling each other in an active galaxy OJ 287.
