Published A baking soda solution for clean hydrogen storage



Scientists investigate the promising properties of a common, Earth-abundant salt.
Published All-electric rideshare fleet could reduce carbon emissions, increase traffic issues



Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.
Published A novel, completely solid, rechargeable air battery



Solid-state batteries use solid electrodes and solid electrolytes, unlike the more commonly known lithium-ion batteries, which use liquid electrolytes. Solid-state batteries overcome various challenges associated with liquid-based batteries, such as flammability, limited voltage, unstable reactants, and poor long-term cyclability and strength. Making advances in this field, researchers recently demonstrated an all-solid-state rechargeable air battery composed of a redox-active organic negative electrode and a proton-conductive polymer electrolyte.
Published Flaring star could be down to young planet's disc inferno



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



An international team of astronomers has announced the second-ever discovery of a multiplanetary circumbinary system.
Published New material transforms light, creating new possibilities for sensors



A new class of materials that can absorb low energy light and transform it into higher energy light might lead to more efficient solar panels, more accurate medical imaging and better night vision goggles.
Published Mori3: A polygon shape-shifting robot for space travel



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'



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 Breaking through the limits of stretchable semiconductors with molecular brakes that harness light



A research team develops a highly stretchable and high-performance organic polymer semiconductor.
Published Using photosynthesis for Martian occupation -- while making space travel more sustainable



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



Astronomers challenge longstanding beliefs about the isolation of 'hot Jupiters' and proposes a new mechanism for understanding the exoplanets' evolution.
Published Sustainable technique to manufacture chemicals



A newly published study details a novel mechanochemistry method that can produce chemicals using less energy and without the use of solvents that produce toxic waste.
Published Breakthrough: Scientists develop artificial molecules that behave like real ones



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 Elusive planets play 'hide and seek' with CHEOPS



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 Long missions, frequent travel take a toll on astronauts' brains



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?



Last year, telescopes around the world registered the brightest cosmic explosion of all time. Astrophysicists can now explain what made it so dazzling.
Published Water molecules define the materials around us



A new paper argues that materials like wood, bacteria, and fungi belong to a newly identified class of matter, 'hydration solids.' The new findings emerged from ongoing research into the strange behavior of spores, dormant bacterial cells.
Published New study identifies mechanism driving the sun's fast wind



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



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 First detection of secondary supermassive black hole in a well-known binary system



An international team of astronomers observed the second one of the two supermassive black holes circling each other in an active galaxy OJ 287.
