Published A 'quantum leap' at room temperature
(via sciencedaily.com) Original source Scientists have achieved a milestone by controlling quantum phenomena at room temperature.
Published How ancient sea creatures can inform soft robotics
(via sciencedaily.com) Original source Fossils of a marine animal that lived 500 million years ago, combined with computer simulations, informed the design of a new soft robot.
Published Researchers show classical computers can keep up with, and surpass, their quantum counterparts
(via sciencedaily.com) Original source A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.
Published How teachers make ethical judgments when using AI in the classroom
(via sciencedaily.com) Original source A teacher's gender and comfort with technology factor into whether artificial intelligence is adopted in the classroom, as shown in a new report.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles
(via sciencedaily.com) Original source Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published AI learns through the eyes and ears of a child
(via sciencedaily.com) Original source Researchers have been skeptical that recent AI advances can tell us much about human learning and development. To address this, a team training an AI model, not on massive data, but on the input that a single child receives. Their findings showed that the model could learn a substantial number of words and concepts using limited slices of what the child experienced.
Published How does a 'reverse sprinkler' work? Researchers solve decades-old physics puzzle
(via sciencedaily.com) Original source For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out how flowing fluids exert forces and move structures, thereby revealing the answer to this long-standing mystery.
Published A long-lasting neural probe
(via sciencedaily.com) Original source An interdisciplinary team of researchers has developed a soft implantable device with dozens of sensors that can record single-neuron activity in the brain stably for months.
Published Scientists design a two-legged robot powered by muscle tissue
(via sciencedaily.com) Original source Compared to robots, human bodies are flexible, capable of fine movements, and can convert energy efficiently into movement. Drawing inspiration from human gait, researchers from Japan crafted a two-legged biohybrid robot by combining muscle tissues and artificial materials. This method allows the robot to walk and pivot.
Published What coffee with cream can teach us about quantum physics
(via sciencedaily.com) Original source A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
Published Discovering the physics behind 300-year-old firefighting methods
(via sciencedaily.com) Original source Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors analyzed the pressure chamber's Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), the length of time pressure builds, and the effects on output flow rate. Next, the authors plan to examine the physiological Windkessel involved in the heart-aorta system.
Published Research team breaks down musical instincts with AI
(via sciencedaily.com) Original source A research team announced they have identified the principle by which musical instincts emerge from the human brain without special learning using an artificial neural network model.
Published Office air conditioning can reduce the risk of harm from wildfire smoke
(via sciencedaily.com) Original source Air conditioning doesn't just cool the air -- it can also reduce the risk of harm from wildfire smoke, new research suggests.
Published DNA origami folded into tiny motor
(via sciencedaily.com) Original source Scientists have created a working nanoscale electomotor. The science team designed a turbine engineered from DNA that is powered by hydrodynamic flow inside a nanopore, a nanometer-sized hole in a membrane of solid-state silicon nitride. The tiny motor could help spark research into future applications such as building molecular factories or even medical probes of molecules inside the bloodstream.
Published Researchers create faster and cheaper way to print tiny metal structures with light
(via sciencedaily.com) Original source Researchers have developed a light-based means of printing nano-sized metal structures that is 480 times faster and 35 times cheaper than the current conventional method. It is a scalable solution that could transform a scientific field long reliant on technologies that are prohibitively expensive and slow. Their method is called superluminescent light projection (SLP).
Published Mini-robots modeled on insects may be smallest, lightest, fastest ever developed
(via sciencedaily.com) Original source Two insect-like robots, a mini-bug and a water strider may be the smallest, lightest and fastest fully functional micro-robots ever known to be created. Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society's International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second.
Published Experiment could test quantum nature of large masses for the first time
(via sciencedaily.com) Original source A new experiment could in principle test the quantumness of an object regardless of its mass or energy.
Published Solid-state qubits: Forget about being clean, embrace mess
(via sciencedaily.com) Original source New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits, a new paper shows.
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.
