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 A baking soda solution for clean hydrogen storage
(via sciencedaily.com) Original source Scientists investigate the promising properties of a common, Earth-abundant salt.
Published All-electric rideshare fleet could reduce carbon emissions, increase traffic issues
(via sciencedaily.com) Original source Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.
Published A novel, completely solid, rechargeable air battery
(via sciencedaily.com) Original source Solid-state batteries use solid electrodes and solid electrolytes, unlike the more commonly known lithium-ion batteries, which use liquid electrolytes. Solid-state batteries overcome various challenges associated with liquid-based batteries, such as flammability, limited voltage, unstable reactants, and poor long-term cyclability and strength. Making advances in this field, researchers recently demonstrated an all-solid-state rechargeable air battery composed of a redox-active organic negative electrode and a proton-conductive polymer electrolyte.
Published New material transforms light, creating new possibilities for sensors
(via sciencedaily.com) Original source A new class of materials that can absorb low energy light and transform it into higher energy light might lead to more efficient solar panels, more accurate medical imaging and better night vision goggles.
Published Mori3: A polygon shape-shifting robot for space travel
(via sciencedaily.com) Original source By combining inspiration from the digital world of polygon meshing and the biological world of swarm behavior, the Mori3 robot can morph from 2D triangles into almost any 3D object. The research shows the promise of modular robotics for space travel.
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.
Published Breaking through the limits of stretchable semiconductors with molecular brakes that harness light
(via sciencedaily.com) Original source A research team develops a highly stretchable and high-performance organic polymer semiconductor.
Published Sustainable technique to manufacture chemicals
(via sciencedaily.com) Original source A newly published study details a novel mechanochemistry method that can produce chemicals using less energy and without the use of solvents that produce toxic waste.
Published Breakthrough: Scientists develop artificial molecules that behave like real ones
(via sciencedaily.com) Original source Scientists have developed synthetic molecules that resemble real organic molecules. A collaboration of researcher can now simulate the behavior of real molecules by using artificial molecules.
Published Schrödinger's cat makes better qubits
(via sciencedaily.com) Original source Drawing from Schrodinger's cat thought experiment, scientists have built a 'critical cat code' qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs.
Published Chatgpt designs a robot
(via sciencedaily.com) Original source Poems, essays and even books -- is there anything the OpenAI platform ChatGPT can't handle? These new AI developments have inspired researchers to dig a little deeper: For instance, can ChatGPT also design a robot? And is this a good thing for the design process, or are there risks?
Published Water molecules define the materials around us
(via sciencedaily.com) Original source A new paper argues that materials like wood, bacteria, and fungi belong to a newly identified class of matter, 'hydration solids.' The new findings emerged from ongoing research into the strange behavior of spores, dormant bacterial cells.
Published More complex than expected: Catalysis under the microscope
(via sciencedaily.com) Original source Usually, catalytic reactions are analyzed by checking which chemicals go into a chemical reactor and which come out. But as it turns out, in order to properly understand and optimize catalysts, much more information is necessary. Scientists developed methods to watch catalytic reactions with micrometer resolution under the microscope -- and the process is much more complex than previously thought.
Published The problems with coal ash start smaller than anyone thought
(via sciencedaily.com) Original source Burning coal doesn't only pollute the air. The resulting ash can leach toxic chemicals into the local environments where it's kept. New research shows that the toxicity of various ash stockpiles relies heavily on its nanoscale structures, which vary widely between sources. The results will help researchers predict which coal ash is most environmentally dangerous.
Published Wireless olfactory feedback system to let users smell in the VR world
(via sciencedaily.com) Original source A research team recently invented a novel, wireless, skin-interfaced olfactory feedback system that can release various odours with miniaturized odor generators (OGs). The new technology integrates odors into virtual reality (VR)/augmented reality (AR) to provide a more immersive experience, with broad applications ranging from 4D movie watching and medical treatment to online teaching.
Published Robot 'chef' learns to recreate recipes from watching food videos
(via sciencedaily.com) Original source Researchers have trained a robotic 'chef' to watch and learn from cooking videos, and recreate the dish itself.

(via sciencedaily.com) Original source Researchers have demonstrated the principle of using spatial correlations in quantum entangled beams of light to encode information and enable its secure transmission.
Published Flat fullerene fragments attractive to electrons
(via sciencedaily.com) Original source Researchers have gained new insights into the unique chemical properties of spherical molecules composed entirely of carbon atoms, called fullerenes. They did it by making flat fragments of the molecules, which surprisingly retained and even enhanced some key chemical properties.
Published The 'breath' between atoms -- a new building block for quantum technology
(via sciencedaily.com) Original source Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.
