Published Scientists develop 3D printed vacuum system that aims to trap dark matter
(via sciencedaily.com) Original source Using a specially designed 3D printed vacuum system, scientists have developed a way to 'trap' dark matter with the aim of detecting domain walls, this will be a significant step forwards in unravelling some of the mysteries of the universe.
Published Breakthrough approach enables bidirectional BCI functionality
(via sciencedaily.com) Original source Brain-computer interfaces or BCIs hold immense potential for individuals with a wide range of neurological conditions, but the road to implementation is long and nuanced for both the invasive and noninvasive versions of the technology. Scientists have now successfully integrated a novel focused ultrasound stimulation to realize bidirectional BCI that both encodes and decodes brain waves using machine learning in a study with 25 human subjects. This work opens up a new avenue to significantly enhance not only the signal quality, but also, overall nonivasive BCI performance by stimulating targeted neural circuits.
Published Pair of merging quasars at cosmic dawn
(via sciencedaily.com) Original source Astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the Universe's earliest formation.
Published Investigating the origins of the crab nebula
(via sciencedaily.com) Original source A team of scientists used NASA's James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus.
Published Researchers use large language models to help robots navigate
(via sciencedaily.com) Original source A technique can plan a trajectory for a robot using only language-based inputs. While it can't outperform vision-based approaches, it could be useful in settings that lack visual data to use for training.
Published High-precision measurements challenge our understanding of Cepheids
(via sciencedaily.com) Original source Scientists have clocked the speed of Cepheid stars -- 'standard candles' that help us measure the size of the universe -- with unprecedented precision, offering exciting new insights about them.
Published Self-assembling and disassembling swarm molecular robots via DNA molecular controller
(via sciencedaily.com) Original source Researchers have succeeded in developing a DNA-based molecular controller. Crucially, this controller enables the autonomous assembly and disassembly of molecular robots, as opposed to manually directing it.
Published Pair plasmas found in deep space can now be generated in the lab
(via sciencedaily.com) Original source Researchers have experimentally generated high-density relativistic electron-positron pair-plasma beams by producing two to three orders of magnitude more pairs than previously reported.
Published Watery planets orbiting dead stars may be good candidates for studying life -- if they can survive long enough
(via sciencedaily.com) Original source The small footprint and dim light of white dwarfs, remnants of stars that have burned through their fuel, may make excellent backdrops for studying planets with enough water to harbor life. The trick is spotting the shadow of a planet against a former star that has withered to a fraction of its size and finding that it's a planet that has kept its water oceans for billions of years even after riding out the star's explosive and violent final throes. A new study of the dynamics of white dwarf systems suggests that, in theory, some watery planets may indeed thread the celestial needles necessary to await discovery and closer scrutiny.
Published Mysterious mini-Neptunes
(via sciencedaily.com) Original source This study discovered mini-Neptunes around four red dwarfs using observations from a global network of ground-based telescopes and the TESS space telescope. These four mini-Neptunes are close to their parent stars, and the three of them are likely to be in eccentric orbits.
Published NASA's Roman mission gets cosmic 'sneak peek' from supercomputers
(via sciencedaily.com) Original source Researchers used supercomputers to create nearly 4 million simulated images depicting the cosmos.
Published Mobile monitoring for an airborne carcinogen in Louisiana's 'Cancer Alley'
(via sciencedaily.com) Original source Louisiana's southeastern corridor is sometimes known colloquially as 'Cancer Alley' for its high cancer incidence rates connected to industrial air pollution. Most of the region's air pollution-related health risks are attributed to ethylene oxide, a volatile compound used to make plastics and sterilize medical equipment. Researchers measured concerning levels of ethylene oxide in this area with mobile optical instruments, a technique they say could improve health risk assessments.
Published Laser tests reveal new insights into key mineral for super-Earths
(via sciencedaily.com) Original source Scientists have for the first time observed how atoms in magnesium oxide morph and melt under ultra-harsh conditions, providing new insights into this key mineral within Earth's mantle that is known to influence planet formation.
Published Robot radiotherapy could improve treatments for eye disease
(via sciencedaily.com) Original source Researchers have successfully used a new robot system to improve treatment for debilitating eye disease.
Published Towards a new era in flexible piezoelectric sensors for both humans and robots
(via sciencedaily.com) Original source Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, researchers tackled these issues by developing a novel piezoelectric composite material made from electrospun polyvinylidene fluoride nanofibers combined with dopamine. Sensors made from this material showed significant performance and stability improvements at a low cost, promising advancements in medicine, healthcare, and robotics.
Published AI-powered simulation training improves human performance in robotic exoskeletons
(via sciencedaily.com) Original source Researchers have demonstrated a new method that leverages artificial intelligence (AI) and computer simulations to train robotic exoskeletons to autonomously help users save energy while walking, running and climbing stairs.
Published Wind from black holes may influence development of surrounding galaxies
(via sciencedaily.com) Original source Clouds of gas in a distant galaxy are being pushed faster and faster -- at more than 10,000 miles per second -- out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy's center. It's a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars.
Published How do supermassive black holes get super massive?
(via sciencedaily.com) Original source By combining forefront X-ray observations with state-of-the-art supercomputer simulations of the buildup of galaxies over cosmic history, researchers have provided the best modeling to date of the growth of the supermassive black holes found in the centers of galaxies.
Published 3D-printed mini-actuators can move small soft robots, lock them into new shapes
(via sciencedaily.com) Original source Researchers have demonstrated miniature soft hydraulic actuators that can be used to control the deformation and motion of soft robots that are less than a millimeter thick. The researchers have also demonstrated that this technique works with shape memory materials, allowing users to repeatedly lock the soft robots into a desired shape and return to the original shape as needed.
Published Scientists spot more Milky Way-like galaxies in early universe
(via sciencedaily.com) Original source Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago. The astronomers have discovered that spiral galaxies were more common in the early universe than previously thought. The scientists found that nearly 30% of galaxies have a spiral structure about 2 billion years after the universe formed. The discovery provides a significant update to the universe's origin story as previously told using data from NASA's Hubble Space Telescope.
