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 Designing environments that are robot-inclusive
(via sciencedaily.com) Original source To overcome issues associated with real-life testing, researchers successfully demonstrated the use of digital twin technology within robot simulation software in assessing a robot's suitability for deployment in simulated built environments.
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 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 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 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 Public have no difficulty getting to grips with an extra thumb, study finds
(via sciencedaily.com) Original source Researchers have shown that members of the public have little trouble in learning very quickly how to use a third thumb -- a controllable, prosthetic extra thumb -- to pick up and manipulate objects. The team tested the robotic device on a diverse range of participants, which they say is essential for ensuring new technologies are inclusive and can work for everyone.
Published 'Invisible tweezers' use robotics and acoustic energy to achieve what human hands cannot
(via sciencedaily.com) Original source Undergoing surgery is seldom a pleasant experience, and it can sometimes be highly invasive. Surgical procedures have evolved steadily over the centuries, growing with the knowledge of anatomy and biology. Innovative methods have also been bolstered with new tools, and a growth in the use of robotics since the 1980s has moved health care forward significantly.
Published Birth of universe's earliest galaxies observed for first time
(via sciencedaily.com) Original source Researchers have now seen the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe.
Published Intriguing nearby world sized between Earth, Venus
(via sciencedaily.com) Original source Astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away.
Published Planet hunters unveil massive catalog of strange worlds
(via sciencedaily.com) Original source While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar system.
Published Team enhances stereotactic neurosurgery precision using MRI-guided multi-stage robotic positioner
(via sciencedaily.com) Original source A research team developed an interactive multi-stage robotic positioner specifically designed for magnetic resonance imaging (MRI)-guided stereotactic neurosurgery.
Published First pictures from Euclid satellite reveal billions of orphan stars
(via sciencedaily.com) Original source The first scientific pictures from the Euclid satellite mission have revealed more than 1,500 billion orphan stars scattered throughout the Perseus cluster of galaxies.
Published Potentially habitable 'exo-Venus' with Earth-like temperature discovered
(via sciencedaily.com) Original source Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.
Published Researchers design new metal-free porous framework materials
(via sciencedaily.com) Original source Researchers have used computational design methods to develop non-metal organic porous framework materials, with potential applications in areas such as catalysis, water capture or hydrogen storage.
Published Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
(via sciencedaily.com) Original source Astronomers have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. The results offer a new way to probe supermassive black holes and their evolution across the universe.
Published Complete stellar collapse: Unusual star system proves that stars can die quietly
(via sciencedaily.com) Original source University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. Their study of an unusual binary star system has resulted in convincing evidence that massive stars can completely collapse and become black holes without a supernova explosion.
Published 3D printing robot creates extreme shock-absorbing shape, with help of AI
(via sciencedaily.com) Original source See how an autonomous robot created a shock-absorbing shape no human ever could -- and what it means for designing safer helmets, packaging, car bumpers, and more.
Published Webb Telescope offers first glimpse of an exoplanet's interior
(via sciencedaily.com) Original source A surprisingly low amount of methane and a super-sized core hide within the cotton candy -- like planet WASP-107 b.
Published Robot-phobia could exacerbate hotel, restaurant labor shortage
(via sciencedaily.com) Original source Using more robots to close labor gaps in the hospitality industry may backfire and cause more human workers to quit, according to a new study. The study, involving more than 620 lodging and food service employees, found that 'robot-phobia' -- specifically the fear that robots and technology will take human jobs -- increased workers' job insecurity and stress, leading to greater intentions to leave their jobs. The impact was more pronounced with employees who had real experience working with robotic technology. It also affected managers in addition to frontline workers.
