Published Tiniest 'starquake' ever detected
(via sciencedaily.com) Original source An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
Published Scientists on the hunt for evidence of quantum gravity's existence at the South Pole
(via sciencedaily.com) Original source An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.
Published Research lights up process for turning CO2 into sustainable fuel
(via sciencedaily.com) Original source Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Published Pairing crypto mining with green hydrogen offers clean energy boost
(via sciencedaily.com) Original source Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Published Astronomers discover 49 new galaxies in under three hours
(via sciencedaily.com) Original source New work aimed to study the star-forming gas in a single radio galaxy. Although the team didn't find any star-forming gas in the galaxy they were studying, they instead discovered other galaxies while inspecting the data. In total, the gas of 49 galaxies was detected.
Published Researchers take major step toward developing next-generation solar cells
(via sciencedaily.com) Original source Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
Published Revolutionizing hydrogen production: Economical and efficient solutions unveiled
(via sciencedaily.com) Original source Scientists introduce superaerophobic three-dimensional nickel nanostructured catalysts for accelerated water electrolysis.
Published Two of the Milky Way's earliest building blocks identified
(via sciencedaily.com) Original source Astronomers have identified what could be two of the Milky Way's earliest building blocks: Named 'Shakti' and 'Shiva', these appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy's initial growth. The new find is the astronomical equivalent of archeologists identifying traces of an initial settlement that grew into a large present-day city.
Published High school students contribute to exoplanet discovery
(via sciencedaily.com) Original source A group of high school students from Oakland, California, made contributions to the field of exoplanet research. Researchers worked with the students to use backpack-sized digital smart telescopes. These young citizen scientists played a role in observing and confirming the nature of a warm and dense sub-Saturn planet, known as TIC 139270665 b, orbiting a metal-rich G2 star.
Published Research suggests how turbulence can be used to generate patterns
(via sciencedaily.com) Original source Physicists show how patterns can emerge from chaos in turbulent fluids.
Published Scientists find one of the most ancient stars that formed in another galaxy
(via sciencedaily.com) Original source The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.
Published Quantum tornado provides gateway to understanding black holes
(via sciencedaily.com) Original source Scientists have created a giant quantum vortex to mimic a black hole in superfluid helium that has allowed them to see in greater detail how analogue black holes behave and interact with their surroundings.
Published Astrophysicist's research could provide a hint in the search for dark matter
(via sciencedaily.com) Original source Dark matter is one of science's greatest mysteries. Although it is believed to make up about 85 percent of the cosmos, scientists know very little about its fundamental nature. Research provides some of the most stringent constraints on the nature of dark matter yet. It also revealed a small hint of a signal that, if real, could be confirmed in the next decade or so.
Published Harnessing hydrogen at life's origin
(via sciencedaily.com) Original source A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.
Published Largest-ever map of universe's active supermassive black holes released
(via sciencedaily.com) Original source Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objects. The new map logs the location of about 1.3 million quasars in space and time, the furthest of which shone bright when the universe was only 1.5 billion years old. The work could help scientists better understand the properties of dark matter.
Published Reimagining the future of solar energy
(via sciencedaily.com) Original source New research suggests that there might be other ways to generate solar energy than just trying to make individual solar cells super-efficient.
Published New research suggests that our universe has no dark matter
(via sciencedaily.com) Original source A new study challenges the current model of the universe by showing that, in fact, it has no room for dark matter.
Published Perovskite solar cells: Vacuum process may offer a short track to commercialization
(via sciencedaily.com) Original source Which process is best suited for mass production of perovskite solar cells? While solvent-based manufacturing processes are used in laboratories around the world, vacuum vapor-phase deposition processes are still the standard for the production of thin films for photovoltaics or organic light-emitting diodes. A new study that reveals major differences in the scientific discussion of these production processes.
Published Cheers! NASA's Webb finds ethanol, other icy ingredients for worlds
(via sciencedaily.com) Original source What do margaritas, vinegar, and ant stings have in common? They contain chemical ingredients that NASA's James Webb Space Telescope has identified surrounding two young protostars known as IRAS 2A and IRAS 23385. Although planets are not yet forming around those stars, these and other molecules detected there by Webb represent key ingredients for making potentially habitable worlds.
Published Explaining a supernova's 'string of pearls'
(via sciencedaily.com) Original source Physicists often turn to the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around supernova 1987A, research suggests. It looks like the same mechanism that breaks up airplane contrails might be at play in forming the clumps of hydrogen gas that ring the remnant of supernova 1987A.
