Published Superconducting amplifiers offer high performance with lower power consumption
(via sciencedaily.com) Researchers have devised a new concept of superconducting microwave low-noise amplifiers for use in radio wave detectors for radio astronomy observations, and successfully demonstrated a high-performance cooled amplifier with power consumption three orders of magnitude lower than that of conventional cooled semiconductor amplifiers. This result is expected to contribute to the realization of large-scale multi-element radio cameras and error-tolerant quantum computers, both of which require a large number of low-noise microwave amplifiers.
Published A sowing, pruning, and harvesting robot for SynecocultureTM farming
(via sciencedaily.com) Synecoculture, a new farming method, involves growing mixed plant species together in high density. However, it requires complex operation since varying species with different growing seasons and growing speeds are planted on the same land. To address this need, researchers have developed a robot that can sow, prune, and harvest plants in dense vegetation growth. Its small, flexible body will help large-scale Synecoculture. This is an important step towards achieving sustainable farming and carbon neutrality.
Published 3D-printed revolving devices can sense how they are moving
(via sciencedaily.com) Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ability to sense their angular position, rotation speed, and direction of rotation.
Published Qubits put new spin on magnetism: Boosting applications of quantum computers
(via sciencedaily.com) Research using a quantum computer as the physical platform for quantum experiments has found a way to design and characterize tailor-made magnetic objects using quantum bits, or qubits. That opens up a new approach to develop new materials and robust quantum computing.
Published Electronic skin as flexible as crocodile skin
(via sciencedaily.com) A research team has developed a crocodile-skin-inspired omnidirectionally stretchable pressure sensor.
Published Resilient bug-sized robots keep flying even after wing damage
(via sciencedaily.com) Researchers have developed resilient artificial muscles that can enable insect-scale aerial robots to effectively recover flight performance after suffering severe damage.
Published Researchers control the degree of twist in nanostructured particles
(via sciencedaily.com) Micron-sized 'bow ties,' self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team has shown.
Published Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots
(via sciencedaily.com) The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.
Published Robots can help improve mental wellbeing at work -- as long as they look right
(via sciencedaily.com) Robots can be useful as mental wellbeing coaches in the workplace -- but perception of their effectiveness depends in large part on what the robot looks like.
Published Researcher solves nearly 60-year-old game theory dilemma
(via sciencedaily.com) A researcher has solved a nearly 60-year-old game theory dilemma called the wall pursuit game, with implications for better reasoning about autonomous systems such as driver-less vehicles.
Published Cleaning up the atmosphere with quantum computing
(via sciencedaily.com) Practical carbon capture technologies are still in the early stages of development, with the most promising involving a class of compounds called amines that can chemically bind with carbon dioxide. Researchers now deploy an algorithm to study amine reactions through quantum computing. An existing quantum computer cab run the algorithm to find useful amine compounds for carbon capture more quickly, analyzing larger molecules and more complex reactions than a traditional computer can.
Published Researchers develop soft robot that shifts from land to sea with ease
(via sciencedaily.com) Most animals can quickly transition from walking to jumping to crawling to swimming if needed without reconfiguring or making major adjustments. Most robots cannot. But researchers have now created soft robots that can seamlessly shift from walking to swimming, for example, or crawling to rolling using a bistable actuator made of 3D-printed soft rubber containing shape-memory alloy springs that react to electrical currents by contracting, which causes the actuator to bend. The team used this bistable motion to change the actuator or robot's shape. Once the robot changes shape, it is stable until another electrical charge morphs it back to its previous configuration.
Published Ultra-soft and highly stretchable hydrogel-based sensor for monitoring overactive bladder
(via sciencedaily.com) Researchers have developed an ultra-soft and highly stretchable tissue-adhesive hydrogel-based multifunctional implantable sensor for monitoring of overactive bladder.
Published New kind of transistor could shrink communications devices on smartphones
(via sciencedaily.com) One month after announcing a ferroelectric semiconductor at the nanoscale thinness required for modern computing components, a team has now demonstrated a reconfigurable transistor using that material. Their work paves the way for single amplifiers that can do the work of multiple conventional amplifiers, among other possibilities.
Published Researchers take a step towards turning interactions that normally ruin quantum information into a way of protecting it
(via sciencedaily.com) A new method for predicting the behavior of quantum devices provides a crucial tool for real-world applications of quantum technology.
Published Artificial intelligence (AI) reconstructs motion sequences of humans and animals
(via sciencedaily.com) Imagine for a moment, that we are on a safari watching a giraffe graze. After looking away for a second, we then see the animal lower its head and sit down. But, we wonder, what happened in the meantime? Computer scientists have found a way to encode an animal's pose and appearance in order to show the intermediate motions that are statistically likely to have taken place.
Published Complex oxides could power the computers of the future
(via sciencedaily.com) Materials scientists describe in two papers how complex oxides can be used to create very energy-efficient magneto-electric spin-orbit (MESO) devices and memristive devices with reduced dimensions.

(via sciencedaily.com) Researchers have developed an algorithm that uses computer vision techniques to accurately measure trees almost five times faster than traditional, manual methods.
Published Integrating humans with AI in structural design
(via sciencedaily.com) A new design process that uses generative design but also seeks feedback from humans is more effective at producing designs that are fully optimized for their purpose.
Published Fighting friction to protect machinery
(via sciencedaily.com) Moving parts in mechanical come into regular contact, leading to wear and tear. Now, researchers have developed a contact control system, driven by artificial intelligence, to greatly reduce contact between damaged parts.
