Published Metaverse could put a dent in global warming



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 Photosynthesis, key to life on Earth, starts with a single photon



A cutting-edge experiment has revealed the quantum dynamics of one of nature's most crucial processes.
Published For experimental physicists, quantum frustration leads to fundamental discovery



A team of physicists recently announced that they have discovered a new phase of matter. Called the 'chiral bose-liquid state,' the discovery opens a new path in the age-old effort to understand the nature of the physical world.
Published New technique in error-prone quantum computing makes classical computers sweat



Today's quantum computers often calculate the wrong answer because of noisy environments that interfere with the quantum entanglement of qubits. IBM Quantum has pioneered a technique that accounts for the noise to achieve reliable results. They tested this error mitigation strategy against supercomputer simulations run by physicists, and for the hardest calculations, the quantum computer bested the supercomputer. This is evidence for the utility of today's noisy quantum computers for performing real-world calculations.
Published A step toward safe and reliable autopilots for flying



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



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 Mori3: A polygon shape-shifting robot for space travel



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



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 Breakthrough: Scientists develop artificial molecules that behave like real ones



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



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



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 New superconducting diode could improve performance of quantum computers and artificial intelligence



A team has developed a more energy-efficient, tunable superconducting diode -- a promising component for future electronic devices -- that could help scale up quantum computers for industry and improve artificial intelligence systems.
Published Wireless olfactory feedback system to let users smell in the VR world



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



Researchers have trained a robotic 'chef' to watch and learn from cooking videos, and recreate the dish itself.
Published Researchers demonstrate secure information transfer using spatial correlations in quantum entangled beams of light



Researchers have demonstrated the principle of using spatial correlations in quantum entangled beams of light to encode information and enable its secure transmission.
Published The 'breath' between atoms -- a new building block for quantum technology



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.
Published Understanding the tantalizing benefits of tantalum for improved quantum processors



Researchers working to improve the performance of superconducting qubits, the foundation of quantum computers, have been experimenting using different base materials in an effort to increase the coherent lifetimes of qubits. The coherence time is a measure of how long a qubit retains quantum information, and thus a primary measure of performance. Recently, scientists discovered that using tantalum in superconducting qubits makes them perform better, but no one has been able to determine why -- until now.
Published A protein mines, sorts rare earths better than humans, paving way for green tech



Rare earth elements, like neodymium and dysprosium, are a critical component to almost all modern technologies, from smartphones to hard drives, but they are notoriously hard to separate from the Earth's crust and from one another. Scientists have discovered a new mechanism by which bacteria can select between different rare earth elements, using the ability of a bacterial protein to bind to another unit of itself, or 'dimerize,' when it is bound to certain rare earths, but prefer to remain a single unit, or 'monomer,' when bound to others.
Published First X-ray of a single atom



Scientists have taken the world's first X-ray SIGNAL (or SIGNATURE) of just one atom. This groundbreaking achievement could revolutionize the way scientists detect the materials.
Published Symmetry breaking by ultrashort light pulses opens new quantum pathways for coherent phonons



Researchers have demonstrated a novel concept for exciting and probing coherent phonons in crystals of a transiently broken symmetry. The key of this concept lies in reducing the symmetry of a crystal by appropriate optical excitation, as has been shown with the prototypical crystalline semimetal bismuth (Bi).
