Published Number cruncher calculates whether whales are acting weirdly
(via sciencedaily.com) Original source We humans can be a scary acquaintance for whales in the wild. This includes marine biologists tagging them with measuring devices to understand them better. These experiences can make whales behave erratically for a while. Such behaviour can affect research quality and highlights an animal ethics dilemma. Now, researchers have figured out how to solve the problems with math.

Published Artificial cells demonstrate that 'life finds a way'
(via sciencedaily.com) Original source A study using a synthetic 'minimal cell' organism stripped down to the 'bare essentials' for life demonstrates the tenacity of organism's power to evolve and adapt, even in the face of an unnatural genome that would seemingly provide little flexibility.
Published Growing bio-inspired polymer brains for artificial neural networks
(via sciencedaily.com) Original source A new method for connecting neurons in neuromorphic wetware has been developed. The wetware comprises conductive polymer wires grown in a three-dimensional configuration, done by applying square-wave voltage to electrodes submerged in a precursor solution. The voltage can modify wire conductance, allowing the network to be trained. This fabricated network is able to perform unsupervised Hebbian learning and spike-based learning.
Published Displays controlled by flexible fins and liquid droplets more versatile, efficient than LED screens
(via sciencedaily.com) Flexible displays that can change color, convey information and even send veiled messages via infrared radiation are now possible, thanks to new research. Engineers inspired by the morphing skins of animals like chameleons and octopuses have developed capillary-controlled robotic flapping fins to create switchable optical and infrared light multipixel displays that are 1,000 times more energy efficient than light-emitting devices.
Published Turning old maps into 3D digital models of lost neighborhoods
(via sciencedaily.com) Original source Imagine strapping on a virtual reality headset and 'walking' through a long-gone neighborhood in your city -- seeing the streets and buildings as they appeared decades ago. That's a very real possibility now that researchers have developed a method to create 3D digital models of historic neighborhoods using machine learning and historic Sanborn Fire Insurance maps.
Published NeuWS camera answers 'holy grail problem' in optical imaging
(via sciencedaily.com) Original source Engineers have demonstrated full-motion video camera technology that can 'see' through light-scattering media. The research could potentially be used in cameras that peer through fog, smoke, driving rain, murky water and parts of the body that hide tumors and other lesions.
Published 'Electronic skin' from bio-friendly materials can track human vital signs with ultrahigh precision
(via sciencedaily.com) Original source Researchers have used materials inspired by molecular gastronomy to create smart wearables that surpassed similar devices in terms of strain sensitivity. They integrated graphene into seaweed to create nanocomposite microcapsules for highly tunable and sustainable epidermal electronics. When assembled into networks, the tiny capsules can record muscular, breathing, pulse, and blood pressure measurements in real-time with ultrahigh precision.
Published Researchers make a quantum computing leap with a magnetic twist
(via sciencedaily.com) Original source Scientists and engineers have announced a significant advancement in developing fault-tolerant qubits for quantum computing. In a pair of articles, they report that, in experiments with flakes of semiconductor materials -- each only a single layer of atoms thick -- they detected signatures of 'fractional quantum anomalous Hall' (FQAH) states. The team's discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons -- strange 'quasiparticles' that have only a fraction of an electron's charge. Some types of anyons can be used to make what are called 'topologically protected' qubits, which are stable against any small, local disturbances.
Published Physicists discover a new switch for superconductivity
(via sciencedaily.com) Original source A study sheds surprising light on how certain superconductors undergo a 'nematic transition' -- unlocking new, superconducting behavior. The results could help identify unconventional superconducting materials.
Published Terahertz-to-visible light conversion for future telecommunications
(via sciencedaily.com) Original source A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open the path to exciting applications in near-future information and communication technologies.
Published Metaverse could put a dent in global warming
(via sciencedaily.com) Original source For many technology enthusiasts, the metaverse has the potential to transform almost every facet of human life, from work to education to entertainment. Now, new research shows it could have environmental benefits, too.
Published A step toward safe and reliable autopilots for flying
(via sciencedaily.com) Original source Researchers developed a machine-learning technique that can autonomously drive a car or fly a plane through a very difficult 'stabilize-avoid' scenario, in which the vehicle must stabilize its trajectory to arrive at and stay within some goal region, while avoiding obstacles.
Published Four-legged robot traverses tricky terrains thanks to improved 3D vision
(via sciencedaily.com) Original source Researchers have developed a new model that trains four-legged robots to see more clearly in 3D. The advance enabled a robot to autonomously cross challenging terrain with ease -- including stairs, rocky ground and gap-filled paths -- while clearing obstacles in its way.

Published Liquid metal sticks to surfaces without a binding agent
(via sciencedaily.com) Original source Everyday materials such as paper and plastic could be transformed into electronic 'smart devices' by using a simple new method to apply liquid metal to surfaces, according to scientists. The study demonstrates a technique for applying a liquid metal coating to surfaces that do not easily bond with liquid metal. The approach is designed to work at a large scale and may have applications in wearable testing platforms, flexible devices, and soft robotics.
