Published How to prevent biofilms in space
(via sciencedaily.com) Original source In experiments aboard the International Space Station, a surface treatment developed engineers prevented the growth of microbial biofims. These films can damage equipment and potentially cause illness.
Published Online AI-based test for Parkinson's disease severity shows promising results
(via sciencedaily.com) A new artificial intelligence tool can help people with Parkinson's disease remotely assess the severity of their symptoms within minutes. While expert neurologists performed slightly better than the AI model, the AI model outperformed the primary care physicians with UPDRS certification.
Published Ravenous black hole consumes three Earths'-worth of star every time it passes
(via sciencedaily.com) Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.
Published Furthest ever detection of a galaxy's magnetic field
(via sciencedaily.com) Astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.
Published Hot Jupiter blows its top
(via sciencedaily.com) The planet HAT-P-32b is losing so much of its atmospheric helium that the trailing gas tails are among the largest structures yet known any planet outside our solar system. Three-dimensional (3D) simulations helped model the flow of the planet's atmosphere. The scientists hope to widen their planet-observing net and survey 20 additional star systems to find more planets losing their atmosphere and learn about their evolution.
Published Webb reveals new structures within iconic supernova
(via sciencedaily.com) NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.
Published An 'introspective' AI finds diversity improves performance
(via sciencedaily.com) Original source An artificial intelligence with the ability to look inward and fine tune its own neural network performs better when it chooses diversity over lack of diversity, a new study finds. The resulting diverse neural networks were particularly effective at solving complex tasks.
Published New AI technology gives robot recognition skills a big lift
(via sciencedaily.com) The day when robots can cook dinner, clear the kitchen table and empty the dishwasher is still a long way off. First, robots need to be able to recognize the many items of different sizes, shapes and brands in our homes. A team has now made a significant advance toward that technology with a robotic system that uses artificial intelligence to help robots better identify and remember objects.
Published Tiny, shape-shifting robot can squish itself into tight spaces
(via sciencedaily.com) Imagine a robot that can wedge itself through the cracks in rubble to search for survivors trapped in the wreckage of a collapsed building. Engineers are working toward to that goal with CLARI, short for Compliant Legged Articulated Robotic Insect.
Published Telescopes help unravel pulsar puzzle
(via sciencedaily.com) With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning dead star. This mysterious object is known to switch between two brightness modes almost constantly, something that until now has been an enigma. But astronomers have now found that sudden ejections of matter from the pulsar over very short periods are responsible for the peculiar switches.
Published Neptune's disappearing clouds linked to the solar cycle
(via sciencedaily.com) Astronomers have uncovered a link between Neptune's shifting cloud abundance and the 11-year solar cycle, in which the waxing and waning of the Sun's entangled magnetic fields drives solar activity.
Published Sensors harnessing light give hope in rehabilitation
(via sciencedaily.com) A research team overcomes limitations of conventional strain sensors using computer vision integrated optical sensors.
Published Brain signals transformed into speech through implants and AI
(via sciencedaily.com) Researchers have succeeded in transforming brain signals into audible speech. By decoding signals from the brain through a combination of implants and AI, they were able to predict the words people wanted to say with an accuracy of 92 to 100%.
Published How being in space impairs astronauts' immune system
(via sciencedaily.com) Original source A new study has examined how T cells of the immune system are affected by weightlessness. The results could explain why astronauts' T cells become less active and less effective at fighting infection.
Published Pros and cons of ChatGPT plugin, Code Interpreter, in education, biology, health
(via sciencedaily.com) Researchers see potential in educational settings for the newest official ChatGPT plugin, called Code Interpreter, they've found limitations for its use by scientists who work with biological data utilizing computational methods to prioritize targeted treatment for cancer and genetic disorders.
Published AI helps robots manipulate objects with their whole bodies
(via sciencedaily.com) A new AI technique enables a robot to develop complex plans for manipulating an object using its entire hand, not just fingertips. This model can generate effective plans in about a minute using a standard laptop.
Published Mysterious Neptune dark spot detected from Earth for the first time
(via sciencedaily.com) Using ESO's Very Large Telescope (VLT), astronomers have observed a large dark spot in Neptune's atmosphere, with an unexpected smaller bright spot adjacent to it. This is the first time a dark spot on the planet has ever been observed with a telescope on Earth. These occasional features in the blue background of Neptune's atmosphere are a mystery to astronomers, and the new results provide further clues as to their nature and origin.
Published New dual-arm robot achieves bimanual tasks by learning from simulation
(via sciencedaily.com) An innovative bimanual robot displays tactile sensitivity close to human-level dexterity using AI to inform its actions.
Published How artificial intelligence gave a paralyzed woman her voice back
(via sciencedaily.com) Researchers have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.
Published Sharing chemical knowledge between human and machine
(via sciencedaily.com) Researchers have developed a platform that uses artificial neural networks to translate chemical structural formulae into machine-readable form. With this platform, they have created a tool with which this information from scientific publications can be automatically fed into databases. Until now, this had to be done literally by hand and was time-consuming.
