Published New quantum effect demonstrated for the first time: Spinaron, a rugby in a ball pit
(via sciencedaily.com) Original source Experimental physicists have demonstrated a new quantum effect aptly named the 'spinaron.' In a meticulously controlled environment and using an advanced set of instruments, they managed to prove the unusual state a cobalt atom assumes on a copper surface. This revelation challenges the long-held Kondo effect -- a theoretical concept developed in the 1960s, and which has been considered the standard model for the interaction of magnetic materials with metals since the 1980s.
Published Engineers develop breakthrough 'robot skin'
(via sciencedaily.com) Original source Smart, stretchable and highly sensitive, a new soft sensor opens the door to a wide range of applications in robotics and prosthetics. When applied to the surface of a prosthetic arm or a robotic limb, the sensor skin provides touch sensitivity and dexterity, enabling tasks that can be difficult for machines such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin, which helps make human interactions safer and more lifelike.
Published A new era for accurate, rapid COVID-19 testing
(via sciencedaily.com) Original source Researchers demonstrate a nanopore-based technique that can detect different variants of SARS-CoV-2, the virus that causes COVID-19. The method was very effective in detecting the Omicron variant of the virus in the saliva of people with COVID-19.
Published Using sound to test devices, control qubits
(via sciencedaily.com) Original source Researchers have developed a system that uses atomic vacancies in silicon carbide to measure the stability and quality of acoustic resonators. What's more, these vacancies could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in this commonly-used material.
Published Plant-based materials give 'life' to tiny soft robots
(via sciencedaily.com) Original source A team of researchers has created smart, advanced materials that will be the building blocks for a future generation of soft medical microrobots. These tiny robots have the potential to conduct medical procedures, such as biopsy, and cell and tissue transport, in a minimally invasive fashion.
Published Electrical control of quantum phenomenon could improve future electronic devices
(via sciencedaily.com) Original source A new electrical method to conveniently change the direction of electron flow in some quantum materials could have implications for the development of next-generation electronic devices and quantum computers. A team of researchers has developed and demonstrated the method in materials that exhibit the quantum anomalous Hall (QAH) effect -- a phenomenon in which the flow of electrons along the edge of a material does not lose energy.
Published Robotic prosthetic ankles improve 'natural' movement, stability
(via sciencedaily.com) Original source Robotic prosthetic ankles that are controlled by nerve impulses allow amputees to move more 'naturally,' improving their stability, according to a new study.
Published Choosing exoskeleton settings like a radio station
(via sciencedaily.com) Original source Taking inspiration from music streaming services, a team of engineers has designed the simplest way for users to program their own exoskeleton assistance settings.
Published Forensic evidence can survive underwater for weeks
(via sciencedaily.com) Original source Forensic fibers can survive underwater for much longer than previously thought -- which could help criminal investigators uncover vital evidence. New research has found that fiber evidence can survive on fabrics underwater for several weeks.
Published Self-correcting quantum computers within reach?
(via sciencedaily.com) Original source Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn't seen much scale-up and commercialization largely due to its inability to self-correct. Quantum computers, unlike classical ones, cannot correct errors by copying encoded data over and over. Scientists had to find another way. Now, a new paper illustrates a quantum computing platform's potential to solve the longstanding problem known as quantum error correction.
Published New cyber algorithm shuts down malicious robotic attack
(via sciencedaily.com) Original source Researchers have designed an algorithm that can intercept a man-in-the-middle (MitM) cyberattack on an unmanned military robot and shut it down in seconds. The algorithm, tested in real time, achieved a 99% success rate.
Published Exploring parameter shift for quantum fisher information
(via sciencedaily.com) Original source Scientists have developed a technique called 'Time-dependent Stochastic Parameter Shift' in the realm of quantum computing and quantum machine learning. This breakthrough method revolutionizes the estimation of gradients or derivatives of functions, a crucial step in many computational tasks.
Published A new way to erase quantum computer errors
(via sciencedaily.com) Original source Researchers have demonstrated a type of quantum eraser. The physicists show that they can pinpoint and correct for mistakes in quantum computing systems known as 'erasure' errors.
Published Unifying matter, energy and consciousness
(via sciencedaily.com) Original source Understanding the interplay between consciousness, energy and matter could bring important insights to our fundamental understanding of reality.
Published Twisted science: New quantum ruler to explore exotic matter
(via sciencedaily.com) Original source Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard for electrical resistance that could calibrate electronic devices directly on the factory floor, eliminating the need to send them to an off-site standards laboratory.
Published Machine learning used to probe the building blocks of shapes
(via sciencedaily.com) Original source Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
Published Could future AI crave a favorite food?
(via sciencedaily.com) Original source Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.
Published These robots helped explain how insects evolved two distinct strategies for flight
(via sciencedaily.com) Original source Robots helped achieve a major breakthrough in our understanding of how insect flight evolved. The study is a result of a six-year long collaboration between roboticists and biophysicists.
Published Insect cyborgs: Towards precision movement
(via sciencedaily.com) Original source Insect cyborgs may sound like something straight out of the movies, but hybrid insect computer robots, as they are scientifically called, could pioneer a new future for robotics. It involves using electrical stimuli to control an insect’s movement. Now, an international research group has conducted a study on the relationship between electrical stimulation in stick insects' leg muscles and the resulting torque (the twisting force that causes the leg to move).
