Published Accelerating the R&D of wearable tech: Combining collaborative robotics, AI
(via sciencedaily.com) Original source Engineers have developed a model that combines machine learning and collaborative robotics to accelerate the design of aerogel materials used in wearable heating applications.
Published Some countries could meet their total electricity needs from floating solar panels
(via sciencedaily.com) Original source Floating solar photovoltaic panels could supply all the electricity needs of some countries, new research has shown. The researchers calculated the daily electrical output for floating photovoltaics (FPV) on nearly 68,000 lakes and reservoirs around the world, using available climate data for each location.
Published Researchers call for strengthening sustainability regulations in laws governing space exploration
(via sciencedaily.com) Original source Researchers call for strengthening existing planetary protection policies beyond the space surrounding Earth to include requirements for preserving the Lunar and Martian environments.
Published Enhancing nanofibrous acoustic energy harvesters with artificial intelligence
(via sciencedaily.com) Original source Scientists have employed artificial intelligence techniques to improve the design and production of nanofibers used in wearable nanofiber acoustic energy harvesters (NAEH). These acoustic devices capture sound energy from the environment and convert it into electrical energy, which can then be applied in useful devices, such as hearing aids.
Published Martian meteorites deliver a trove of information on Red Planet's structure
(via sciencedaily.com) Original source Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists have analyzed. These results are important for understanding not only how Mars formed and evolved, but also for providing precise data that can inform recent NASA missions like Insight and Perseverance and the Mars Sample Return.
Published Overcoming barriers to heat pump adoption in cold climates and avoiding the 'energy poverty trap'
(via sciencedaily.com) Original source Converting home heating systems from natural gas furnaces to electric heat pumps is seen as a way to address climate change by reducing greenhouse gas emissions.
Published AI-controlled stations can charge electric cars at a personal price
(via sciencedaily.com) Original source As more and more people drive electric cars, congestion and queues can occur when many people need to charge at the same time. A new study shows how AI-controlled charging stations, through smart algorithms, can offer electric vehicle users personalized prices, and thus minimize both price and waiting time for customers. But the researchers point to the importance of taking the ethical issues seriously, as there is a risk that the artificial intelligence exploits information from motorists.
Published Glimpses of a volcanic world: New telescope images of Jupiter's moon Io rival those from spacecraft
(via sciencedaily.com) Original source Combining a new imaging instrument with the powerful adaptive optics capabilities of the Large Binocular Telescope, astronomers have captured a volcanic event on Jupiter's moon Io at a resolution never before achieved with Earth-based observations.
Published Medium and mighty: Intermediate-mass black holes can survive in globular clusters
(via sciencedaily.com) Original source New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed stars. The first ever star-by-star massive cluster-formation simulations revealed that sufficiently dense molecular clouds, the 'birthing nests' of star clusters, can give birth to very massive stars that evolve into intermediate-mass black holes.
Published New method makes hydrogen from solar power and agricultural waste
(via sciencedaily.com) Original source Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
Published NASA's James Webb Space Telescope finds most distant known galaxy
(via sciencedaily.com) Original source Over the last two years, scientists have used NASA's James Webb Space Telescope to explore what astronomers refer to as Cosmic Dawn -- the period in the first few hundred million years after the big bang where the first galaxies were born.
Published Controlling ion transport for a blue energy future
(via sciencedaily.com) Original source Researchers probed the transit of cations across a nanopore membrane for the generation of osmotic energy. The team controlled the passage of cations across the membrane using a voltage applied to a gate electrode. This control allowed the cation-selective transport to be tuned from essentially zero to complete cation selectivity. The findings are expected to support the application of blue energy solutions for sustainable energy alternatives worldwide.
Published Moon orbiting 'dinky' asteroid is actually two tiny moons stuck together
(via sciencedaily.com) Original source The moon orbiting the asteroid Dinkinesh is actually two tiny moons stuck together. Collectively called 'Selam,' the two moonlets bring new insight into the complex processes behind planetary formation and evolution.
Published The case of the missing black holes
(via sciencedaily.com) Original source Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.
Published New technique offers more precise maps of the Moon's surface
(via sciencedaily.com) Original source A new study may help redefine how scientists map the surface of the Moon, making the process more streamlined and precise than ever before.
Published Study is step towards energy-efficient quantum computing in magnets
(via sciencedaily.com) Original source Researchers have managed to generate propagating spin waves at the nanoscale and discovered a novel pathway to modulate and amplify them. Their discovery could pave the way for the development of dissipation free quantum information technologies. As the spin waves do not involve electric currents these chips will be free from associated losses of energy. The rapidly growing popularity of artificial intelligence comes with an increasing desire for fast and energy efficient computing devices and calls for novel ways to store and process information. The electric currents in conventional devices suffer from losses of energy and subsequent heating of the environment.
Published Wind farms are cheaper than you think -- and could have prevented Fukushima, says global review
(via sciencedaily.com) Original source Offshore wind could have prevented the Fukushima disaster, according to a review of wind energy.
Published 'The magic of making electricity from metals and air' The vexing carbonate has achieved it!
(via sciencedaily.com) Original source Team develops a high-energy, high-efficiency all-solid-state Na-air battery platform.
Published Mystery of 'slow' solar wind unveiled by Solar Orbiter mission
(via sciencedaily.com) Original source Scientists have come a step closer to identifying the mysterious origins of the 'slow' solar wind, using data collected during the Solar Orbiter spacecraft's first close journey to the Sun.
Published Harnessing green energy from plants depends on their circadian rhythms
(via sciencedaily.com) Original source Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process. A study closely examined the differences in voltage caused by the concentrations of ions, types of ions, and pH of the fluid plants transport, tying the voltage changes to the plant's circadian rhythm that causes adjustments day and night. According to the authors, this consistent, cyclic voltage creation could be harnessed as an energy source.
