Published 'Smart glove' can boost hand mobility of stroke patients
(via sciencedaily.com) Original source This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.
Published Pain-based weather forecasts could influence actions
(via sciencedaily.com) Original source For individuals who experience chronic pain, weather can be a significant factor in their day-to-day plans. In a recent study, about 70 percent of respondents said they would alter their behavior based on weather-based pain forecasts.
Published Are bugs bugging humans or the other way around? Study reveals a few surprises
(via sciencedaily.com) Original source Research has determined key factors that impact biodiversity among spiders and insects in urban areas. The response of specific groups varied significantly, surprising the researchers. The study findings can help urban planners, landscapers, builders and homeowners make choices that increase biodiversity. Dozens of species previously unknown to science came to light through the study.
Published Astronomers make rare exoplanet discovery, and a giant leap in detecting Earth-like bodies
(via sciencedaily.com) Original source Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion -- shedding light on the formation of planets like Earth.
Published Transparent brain implant can read deep neural activity from the surface
(via sciencedaily.com) Original source Researchers have developed a neural implant that provides information about activity deep inside the brain while sitting on its surface. The implant is made up of a thin, transparent and flexible polymer strip that is packed with a dense array of graphene electrodes. The technology, tested in transgenic mice, brings the researchers a step closer to building a minimally invasive brain-computer interface (BCI) that provides high-resolution data about deep neural activity by using recordings from the brain surface.
Published Revolutionizing real-time data processing with edge computing and reservoir technology
(via sciencedaily.com) Original source Traditional cloud computing faces various challenges when processing large amounts of data in real time. 'Edge' computing is a promising alternative and can benefit from devices known as physical reservoirs. Researchers have now developed a novel memristor device for this purpose. It responds to electrical and optical signals and overcomes real-time processing limitations. When tested, it achieved up to 90.2% accuracy in digit identification, demonstrating its potential for applications in artificial intelligence systems and beyond.
Published New study pinpoints the weaknesses in AI
(via sciencedaily.com) Original source ChatGPT and other solutions built on Machine Learning are surging. But even the most successful algorithms have limitations. Researchers have now proven mathematically that apart from simple problems it is not possible to create algorithms for AI that will always be stable. The study may lead to guidelines on how to better test algorithms and reminds us that machines do not have human intelligence after all.
Published Integrating dimensions to get more out of Moore's Law and advance electronics
(via sciencedaily.com) Original source Engineers suggest a way to fit more transistors on a chip by seamlessly implementing 3D integration with 2D materials.
Published Researchers developing AI to make the internet more accessible
(via sciencedaily.com) Original source In an effort to make the internet more accessible for people with disabilities, researchers have begun developing an artificial intelligence agent that could complete complex tasks on any website using simple language commands.
Published With only the pawprints, researchers study elusive bobcat
(via sciencedaily.com) Original source With DNA recovered from animal tracks, scientists revealed information about the ancestry and microbial community of bobcats without having to sample the animal directly.
Published New soft robots roll like tires, spin like tops and orbit like moons
(via sciencedaily.com) Original source Researchers have developed a new soft robot design that engages in three simultaneous behaviors: rolling forward, spinning like a record, and following a path that orbits around a central point. The device, which operates without human or computer control, holds promise for developing soft robotic devices that can be used to navigate and map unknown environments.
Published Researchers rely on Earth's magnetic field to verify an event mentioned in the Old Testament
(via sciencedaily.com) Original source A new study scientifically corroborates an event described in the Second Book of Kings -- the conquest of the Philistine city of Gath by Hazael King of Aram. The method is based on measuring the magnetic field recorded in burnt bricks. The researchers say that the findings are important for determining the intensity of the fire and the scope of destruction in Gath, and also for understanding construction practices in the region.
Published From NYC to DC and beyond, cities on the East Coast are sinking
(via sciencedaily.com) Original source Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.
Published Electronic 'soil' enhances crop growth
(via sciencedaily.com) Original source Barley seedlings grow on average 50% more when their root system is stimulated electrically through a new cultivation substrate. Researchers have now developed an electrically conductive 'soil' for soil-less cultivation, known as hydroponics.
Published Wireless tracking system could help improve the XR experience
(via sciencedaily.com) Original source Engineers developed a technology that delivers centimeter-level accuracy for real-time tracking in extended reality (XR) applications. It uses wireless signals to ensure precise asset localization and smooth tracking, promising to enhance virtual gaming experiences and workplace safety.
Published Blue PHOLEDs: Final color of efficient OLEDs finally viable in lighting
(via sciencedaily.com) Original source Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours. The new phosphorescent OLEDs, commonly referred to as PHOLEDs, can maintain 90% of the blue light intensity for 10-14 times longer than other designs that emit similar deep blue colors. That kind of lifespan could finally make blue PHOLEDs hardy enough to be commercially viable in lights that meet the Department of Energy's 50,000-hour lifetime target. Without a stable blue PHOLED, OLED lights need to use less-efficient technology to create white light.
