Published Wind, solar could replace coal power in Texas
(via sciencedaily.com) A fraction of the wind and solar projects already proposed in Texas could eliminate the state's remaining coal power plants and their emissions, according to engineers.
Published Tiny magnets could hold the secret to new quantum computers
(via sciencedaily.com) Scientists have discovered a type of magnetic behavior that could help enable magnetically based quantum devices.
Published Why groundwater is one of our most precious resources
(via sciencedaily.com) From the Murray-Darling system to Great Artesian Basin, 'invisible' underground groundwater is often the only water supply available across the vast majority Australia where its annual contribution to GDP is estimated at more than $6.8 billion a year. However, overuse of groundwater during droughts and aquifer depletion has already seen water crises, including in Australia's 'food bowl' the Murray-Darling Basin (MDB), California and Cape Town in South Africa, with more likely to follow with groundwater management largely reactive and unlikely to avert more crises as climate change accelerates and populations grow.
Published Soil erosion and wildfire another nail in coffin for Triassic era
(via sciencedaily.com) New research has revealed that soil erosion and wildfires contributed to a mass extinction event 201 million years ago that ended the Triassic era and paved the way for the rise of dinosaurs in the Jurassic period.
Published Could we make cars out of petroleum residue?
(via sciencedaily.com) Researchers have developed a way to make lightweight fibers, for possible use in the bodies of cars, out of an ultracheap feedstock: the waste material from the refining of petroleum.
Published Turning any camera into a polarization camera
(via sciencedaily.com) Researchers have developed a metasurface attachment that can turn just about any camera or imaging system, even off-the-shelf systems, into polarization cameras. The attachment uses a metasurface of subwavelength nanopillars to direct light based on its polarization and compiles an image that captures polarization at every pixel.
Published Smoke from major wildfires destroys the ozone layer
(via sciencedaily.com) A new study shows that smoke from wildfires destroys the ozone layer. Researchers caution that if major fires become more frequent with a changing climate, more damaging ultraviolet radiation from the sun will reach the ground.
Published Mathematical paradoxes demonstrate the limits of AI
(via sciencedaily.com) Humans are usually pretty good at recognizing when they get things wrong, but artificial intelligence systems are not. According to a new study, AI generally suffers from inherent limitations due to a century-old mathematical paradox.
Published The oxidation of volcanoes -- a magma opus
(via sciencedaily.com) A new study unlocks the science behind a key ingredient -- namely oxygen -- in some of the world's most violent volcanoes. The research offers a new model for understanding the oxidation state of arc magmas, the lavas that form some volcanoes, such as the one that erupted dramatically in Tonga earlier this year. The plume from Tonga's underwater volcanic eruption on Jan. 15 rose 36 miles into the air. Ash from the volcano reached the mesosphere, Earth's third layer of atmosphere.
Published Creutzfeldt-Jakob disease treatment shows promising early results
(via sciencedaily.com) A promising new treatment for Creutzfeldt-Jakob disease (CJD) has shown 'very encouraging' early results following its use in six patients.
Published Cheaper, more efficient ways to capture carbon
(via sciencedaily.com) Researchers have developed a new tool that could lead to more efficient and cheaper technologies for capturing heat-trapping gases from the atmosphere and converting them into beneficial substances, like fuel or building materials.
Published New acoustic fabric converts audible sounds into electrical signals
(via sciencedaily.com) Researchers have developed a new acoustic fabric converts audible sounds into electrical signals. They designed a fabric that works like a microphone, converting sound first into mechanical vibrations, then into electrical signals, similarly to how our ears hear.
Published Toward a quantum computer that calculates molecular energy
(via sciencedaily.com) Researchers have developed an algorithm that uses the most quantum bits to date to calculate ground state energy, the lowest-energy state in a quantum mechanical system. The discovery could make it easier to design new materials.
Published Wax-coated sand keeps soil wet longer, improves crop yields in arid regions
(via sciencedaily.com) Dry, hot regions are difficult places to grow plants because the soil dries out quickly. As a result, farmers in arid and semi-arid regions irrigate their fields with buried networks of irrigation tubing and cover the ground with plastic sheets. But plastic sheets are expensive and create waste. Now, researchers have developed a simple, biodegradable ground cover -- wax-coated sand -- which keeps soil wet and increases crop yields.
Published Nuclear reactor power levels can be monitored using seismic and acoustic data
(via sciencedaily.com) Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study.
Published Ancient ice reveals scores of gigantic volcanic eruptions
(via sciencedaily.com) Ice cores drilled in Antarctica and Greenland have revealed gigantic volcanic eruptions during the last ice age. Sixty-nine of these were larger than any eruption in modern history. According to the physicists behind the research, these eruptions can teach us about our planet's sensitivity to climate change.
Published Intensity control of projectors in parallel: A doorway to an augmented reality future
(via sciencedaily.com) A challenge to adopting augmented reality (AR) in wider applications is working with dynamic objects, owing to a delay between their movement and the projection of light onto their new position. But, scientists may have a workaround. They have developed a method that uses multiple projectors while reducing delay time. Their method could open the door to a future driven by AR, helping us live increasingly technology-centered lives.
Published Stackable 'holobricks' can make giant 3D images
(via sciencedaily.com) Researchers have developed a new method to display highly realistic holographic images using 'holobricks' that can be stacked together to generate large-scale holograms.
Published Look! Up in the sky! Is it a planet? Nope, just a star
(via sciencedaily.com) Original source Among thousands of known exoplanets, astronomers have flagged three that are actually stars.
Published Making green energy greener: Researchers propose method for wind turbine blades' recycling
(via sciencedaily.com) Wind turbine blades made from glass fiber-reinforced polymer (GFRP) laminate composites can serve for up to 25 years. After that, they end up in landfills which has become a real challenge for the renewable energy industry. Researchers have proposed a method for wind turbine blades' recycling. Using pyrolysis, they broke the composite materials into their constituent parts. According to scientists, the extracted materials can be reused, and the process is virtually waste-free.
