Published Liquid metal-based electronic logic device that mimics intelligent prey-capture mechanism of Venus flytrap
(via sciencedaily.com) Original source A research team has developed a liquid metal-based electronic logic device that mimics the intelligent prey-capture mechanism of Venus flytraps. Exhibiting memory and counting properties, the device can intelligently respond to various stimulus sequences without the need for additional electronic components. The intelligent strategies and logic mechanisms in the device provide a fresh perspective on understanding 'intelligence' in nature and offer inspiration for the development of 'embodied intelligence'.
Published Novel diamond quantum magnetometer for ambient condition magnetoencephalography
(via sciencedaily.com) Original source A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.
Published People feel more connected to 'tweezer-like' bionic tools that don't resemble human hands
(via sciencedaily.com) Original source Some say the next step in human evolution will be the integration of technology with flesh. Now, researchers have used virtual reality to test whether humans can feel embodiment -- the sense that something is part of one's body -- toward prosthetic 'hands' that resemble a pair of tweezers. They report that participants felt an equal degree of embodiment for the tweezer-hands and were also faster and more accurate in completing motor tasks in virtual reality than when they were equipped with a virtual human hand.
Published Flapping frequency of birds, insects, bats and whales described by universal equation
(via sciencedaily.com) Original source A single universal equation can closely approximate the frequency of wingbeats and fin strokes made by birds, insects, bats and whales, despite their different body sizes and wing shapes, researchers report in a new study.
Published Babies use 'helpless' infant period to learn powerful foundation models, just like ChatGPT
(via sciencedaily.com) Original source Babies' brains are not as immature as previously thought, rather they are using the period of postnatal 'helplessness' to learn powerful foundation models similar to those underpinning generative Artificial Intelligence, according to a new study.
Published Using AI to decode dog vocalizations
(via sciencedaily.com) Original source Have you ever wished you could understand what your dog is trying to say to you? Researchers are exploring the possibilities of AI, developing tools that can identify whether a dog's bark conveys playfulness or aggression.
Published Unraveling the physics of knitting
(via sciencedaily.com) Original source A team used experiments and simulations to quantify and predict how knit fabric response can be programmed. By establishing a mathematical theory of knitted materials, the researchers hope that knitting -- and textiles in general -- can be incorporated into more engineering and manufacturing applications.
Published Shining a light on molecules: L-shaped metamaterials can control light direction
(via sciencedaily.com) Original source Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or handedness, could provide a way to identify and sort specific molecules for use in biomedicine applications, but researchers have had limited control over the direction of the waves -- until now.
Published A technique for more effective multipurpose robots
(via sciencedaily.com) Original source MIT researchers developed a technique to combine robotics training data across domains, modalities, and tasks using generative AI models. They create a combined strategy from several different datasets that enables a robot to learn to perform new tasks in unseen environments.
Published Groundbreaking progress in quantum physics: How quantum field theories decay and fission
(via sciencedaily.com) Original source An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives elementary particles mass and triggers phase transitions, using the concept of 'magnetic quivers.'
Published Enhancing nanofibrous acoustic energy harvesters with artificial intelligence
(via sciencedaily.com) Original source Scientists have employed artificial intelligence techniques to improve the design and production of nanofibers used in wearable nanofiber acoustic energy harvesters (NAEH). These acoustic devices capture sound energy from the environment and convert it into electrical energy, which can then be applied in useful devices, such as hearing aids.
Published The coldest lab in New York has new quantum offering
(via sciencedaily.com) Original source Physicists describe the successful creation of a molecular Bose-Einstein condensate (BEC). Made up of dipolar sodium-cesium molecules that were cooled with the help of microwave shielding to just 5 nanoKelvin and lasted for up to two seconds, the new molecular BEC will help scientists explore a number of different quantum phenomena, including new types of superfluidity, and enable the creation of quantum simulators to ecreate the enigmatic properties of complex materials, like solid crystals.
Published Scientists develop most sensitive way to observe single molecules
(via sciencedaily.com) Original source A technical achievement marks a significant advance in the burgeoning field of observing individual molecules without the aid of fluorescent labels. While these labels are useful in many applications, they alter molecules in ways that can obscure how they naturally interact with one another. The new label-free method makes the molecules so easy to detect, it is almost as if they had labels.
Published The thinnest lens on Earth, enabled by excitons
(via sciencedaily.com) Original source Lenses are used to bend and focus light. Normal lenses rely on their curved shape to achieve this effect, but physicists have made a flat lens of only three atoms thick which relies on quantum effects. This type of lens could be used in future augmented reality glasses.
Published Theoretical quantum speedup with the quantum approximate optimization algorithm
(via sciencedaily.com) Original source Researchers demonstrated a quantum algorithmic speedup with the quantum approximate optimization algorithm, laying the groundwork for advancements in telecommunications, financial modeling, materials science and more.

Published Study is step towards energy-efficient quantum computing in magnets
(via sciencedaily.com) Original source Researchers have managed to generate propagating spin waves at the nanoscale and discovered a novel pathway to modulate and amplify them. Their discovery could pave the way for the development of dissipation free quantum information technologies. As the spin waves do not involve electric currents these chips will be free from associated losses of energy. The rapidly growing popularity of artificial intelligence comes with an increasing desire for fast and energy efficient computing devices and calls for novel ways to store and process information. The electric currents in conventional devices suffer from losses of energy and subsequent heating of the environment.

The team tested the robotic device on a diverse range of participants, which they say is essential for ensuring new technologies are inclusive and can work for everyone.
Published Close to 1 in 2 surveyed say they would use air taxis in the future
(via sciencedaily.com) Original source Through a study of 1,002 participants, scientists have found that almost half (45.7 per cent) say they intend to use air taxis when they become available, with over one-third (36.2 per cent) planning to do so regularly. According to the findings, the intention to take autonomous air taxis is associated with factors such as trust in the AI technology deployed in air taxis, hedonic motivation (the fun or pleasure derived from using technology), performance expectancy (the degree to which users expect that using the system will benefit them), and news media attention (the amount of attention paid to news about air taxis).
