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 Metal-poor stars are more life-friendly
(via sciencedaily.com) Original source A star's chemical composition strongly influences the ultraviolet radiation it emits into space and thus the conditions for the emergence of life in its neighborhood.
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 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.
Published How did Earth get its water?
(via sciencedaily.com) Original source Our planet's water could have originated from interactions between the hydrogen-rich atmospheres and magma oceans of the planetary embryos that comprised Earth's formative years.
Published Humans need Earth-like ecosystem for deep-space living
(via sciencedaily.com) Original source Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.
Published Electrification push will have enormous impacts on critical metals supply chain
(via sciencedaily.com) Original source The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as vehicle electrification speeds up and nations work to reduce greenhouse gas emissions through mid-century. This surge in demand will also create a variety of economic and supply-chain problems, according to new research.
Published Photonic filter separates signals from noise to support future 6G wireless communication
(via sciencedaily.com) Original source Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The device is expected to help next-generation wireless communication technologies efficiently convey data in an environment that is becoming crowded with signals.
Published Lightning strike creates phosphorus material
(via sciencedaily.com) Original source A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.
Published New findings that map the universe's cosmic growth support Einstein's theory of gravity
(via sciencedaily.com) Original source Research by the Atacama Cosmology Telescope collaboration has culminated in a groundbreaking new image that reveals the most detailed map of dark matter distributed across a quarter of the entire sky, reaching deep into the cosmos. Findings provide further support to Einstein's theory of general relativity, which has been the foundation of the standard model of cosmology for more than a century, and offers new methods to demystify dark matter.
Published Researchers discover new circuit element
(via sciencedaily.com) Original source Researchers have identified a new circuit element known as a meminductor.
Published Cities will need more resilient electricity networks to cope with extreme weather
(via sciencedaily.com) Original source Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.
