Published Astrophysicists reveal the nature of dark matter through the study of crinkles in spacetime
(via sciencedaily.com) Original source Astrophysicists have provided the most direct evidence yet that Dark Matter does not constitute ultramassive particles as is commonly thought but instead comprises particles so light that they travel through space like waves. Their work resolves an outstanding problem in astrophysics first raised two decades ago: why do models that adopt ultramassive Dark Matter particles fail to correctly predict the observed positions and the brightness of multiple images of the same galaxy created by gravitational lensing?
Published Scientists detect seismic waves traveling through Martian core
(via sciencedaily.com) Original source New NASA InSight research reveals that Mars has a liquid core rich in sulfur and oxygen, leading to new clues about how terrestrial planets form, evolve and potentially sustain life.
Published Pioneering research sheds new light on the origins and composition of planet Mars
(via sciencedaily.com) Original source A new study has uncovered intriguing insights into the liquid core at the centre of Mars, furthering understanding of the planet's formation and evolution.
Published Transforming highways for high-speed travel and energy transport
(via sciencedaily.com) Original source Researchers developed a proof of concept for a superconducting highway that could transport vehicles and electricity, cooling the necessary superconductors with a pipeline of liquid hydrogen. Most magnetic levitation designs feature the superconductor inside the vehicle, which is suspended above a magnetic track. The authors decided to flip that arrangement upside down, putting the superconductor on the ground and giving each vehicle a magnet. The result is a system with multiple uses, placing it within the realm of affordability.
Published Cryo-imaging lifts the lid on fuel cell catalyst layers
(via sciencedaily.com) Original source Thanks to a novel combination of cryogenic transmission electron tomography and deep learning, EPFL researchers have provided a first look at the nanostructure of platinum catalyst layers, revealing how they could be optimized for fuel cell efficiency.
Published Making better measurements of the composition of galaxies
(via sciencedaily.com) Original source A study using data from telescopes on Earth and in the sky resolves a problem plaguing astronomers working in the infrared and could help make better observations of the composition of the universe with the James Webb Space Telescope and other instruments.
Published A team creates 'quantum composites' for various electrical and optical innovations
(via sciencedaily.com) Original source A team has shown in the laboratory the unique and practical function of newly created materials, which they called quantum composites, that may advance electrical, optical, and computer technologies.
Published Could this copycat black hole be a new type of star?
(via sciencedaily.com) Original source It looks like a black hole and bends light like a black hole, but it could actually be a new type of star. Though the mysterious object is a hypothetical mathematical construction, new simulations by Johns Hopkins researchers suggest there could be other celestial bodies in space hiding from even the best telescopes on Earth.
Published Tiny biobattery with 100-year shelf life runs on bacteria
(via sciencedaily.com) Original source A tiny biobattery that could still work after 100 years has been developed.
Published Next decade decisive for PV growth on the path to 2050
(via sciencedaily.com) Original source Global experts on solar power strongly urge a commitment to the continued growth of photovoltaic (PV) manufacturing and deployment to power the planet, arguing that lowballing projections for PV growth while waiting for a consensus on other energy pathways or the emergence of technological last-minute miracles 'is no longer an option.'
Published How electricity can heal wounds three times as fast
(via sciencedaily.com) Original source Chronic wounds are a major health problem for diabetic patients and the elderly -- in extreme cases they can even lead to amputation. Using electric stimulation, researchers have developed a method that speeds up the healing process, making wounds heal three times faster.
Published A solar hydrogen system that co-generates heat and oxygen
(via sciencedaily.com) Original source Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Published Playing hide and seek with planets
(via sciencedaily.com) Original source An international team of astronomers announced the first exoplanet discovered through a combined approach of direct imaging and precision measurements of a star's motion on the sky. This new method promises to improve the efficiency of exoplanet searches, paving the way for the discovery of an Earth twin.
Published New exoplanet discovered
(via sciencedaily.com) Original source Astronomers report the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a planet by measuring the position of the star it orbits. Data from the Subaru Telescope in Hawai`i and space telescopes from the European Space Agency (ESA) were integral to the team's discovery.
Published Scientists create high-efficiency sustainable solar cells for IoT devices with AI-powered energy management
(via sciencedaily.com) Original source Researchers have created environmentally-friendly, high-efficiency photovoltaic cells that harness ambient light to power internet of Things (IoT) devices.
Published A sharper look at the M87 black hole
(via sciencedaily.com) Original source The iconic image of the supermassive black hole at the center of M87 has gotten its first official makeover based on a new machine learning technique called PRIMO. The team used the data achieved the full resolution of the array.
Published M87 in 3D: New view of galaxy helps pin down mass of the black hole at its core
(via sciencedaily.com) Original source From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, whose central supermassive black hole has already been imaged by the Event Horizon Telescope. M87 turns out to be triaxial, like a potato. The revised view provides a more precise measure of the mass of the central black hole: 5.37 billion solar masses.
Published James Webb Space Telescope images challenge theories of how universe evolved
(via sciencedaily.com) Original source Astronomers find that six of the earliest and most massive galaxy candidates observed by the James Webb Space Telescope so far appear to have converted nearly 100% of their available gas into stars, a finding at odds with the reigning model of cosmology.
Published Engineers devise technology to prevent fouling in photobioreactors for CO2 capture
(via sciencedaily.com) Original source A new, inexpensive technology can limit the buildup of algae on the walls of photobioreactors that can help convert carbon dioxide into useful products. Reducing this fouling avoids costly cleanouts and allows more photosynthesis to happen within tanks.
Published Researchers discover tiny galaxy with big star power using James Webb telescope
(via sciencedaily.com) Original source Using new observations from the James Webb Space Telescope, astronomers looked more than 13 billion years into the past to discover a unique, minuscule galaxy that could help astronomers learn more about galaxies that were present shortly after the Big Bang.
