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 Major advance in super-resolution fluorescence microscopy
(via sciencedaily.com) Pushing the MINFLUX technique to higher spatial and temporal precision allows protein dynamics to be observed under physiological conditions.
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 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 Game-changing high-performance semiconductor material could help slash heat emissions
(via sciencedaily.com) Researchers have engineered a material with the potential to dramatically cut the amount of heat power plants release into the atmosphere.
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 Scientists transform algae into unique functional perovskites with tunable properties
(via sciencedaily.com) Scientists have transformed single-cell algae into functional perovskite materials. The team has converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production. The method can be applied to the mass production of perovskites with tunable structural and electro-optical properties from single-celled organisms.
Published Are piezoelectrics good for generating electricity? Perhaps, but we must decide how to evaluate them
(via sciencedaily.com) A 'best practice' protocol for researchers developing piezoelectric materials has been developed by scientists. The protocol was developed by an international team led by physicists in response to findings that experimental reports lack consistency. The researchers made the shocking discovery that nine out of 10 scientific papers miss experimental information that is crucial to ensure the reproducibility of the reported work.

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.
