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 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 Source-shifting metastructures composed of only one resin for location camouflaging



Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer for location camouflage. Utilizing inverse design based on topology optimization, this development could pave the way for advanced augmented reality and holography technology.
Published Robot centipedes go for a walk



Researchers show how their multilegged walking robot can be steered by inducing a dynamic instability. By making the couplings between segments more flexible, the robot changes from walking straight to moving in a curved path. This work can lead to more energy-efficient and reliable robotic navigation of terrain.
Published Protein-based nano-'computer' evolves in ability to influence cell behavior



The first protein-based nano-computing agent that functions as a circuit has been created. The milestone puts them one step closer to developing next-generation cell-based therapies to treat diseases like diabetes and cancer.
Published Effective as a collective: Researchers investigate the swarming behavior of microrobots



Miniaturization is progressing rapidly in just any field and the trend towards the creation of ever smaller units is also prevalent in the world of robot technology. In the future, minuscule robots used in medical and pharmaceutical applications might be able to transport medication to targeted sites in the body. Statistical physics can contribute to the foundations for the development of such technologies.
Published Robots and Rights: Confucianism Offers Alternative



As robots assume more roles in the world, a new analysis reviewed research on robot rights, concluding that granting rights to robots is a bad idea. Instead, the article looks to Confucianism to offer an alternative.
Published Making the structure of 'fire ice' with nanoparticles



Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers have shown how to achieve this through computer simulations.
Published The metaverse can lead to better science



One researcher says we should look beyond the hype to see how virtual reality can make scientists more effective. But to realize the benefits, researchers must also plan well and avoid potential pitfalls.
Published Scientists propose revolution in complex systems modelling with quantum technologies



Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly re-duced memory.
Published Medical 'microrobots' could one day treat bladder disease, other human illnesses



Engineers have designed a new class of 'microrobots' several times smaller than the width of a human hair that may be able to treat human illnesses like interstitial cystitis -- a painful bladder disease that affects millions of Americans.
Published Quantum matter breakthrough: Tuning density waves



Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems in physics.
Published Researchers build bee robot that can twist



A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.
Published Wiring up quantum circuits with light



The number of qubits in superconducting quantum computers has risen rapidly during the last years, but further growth is limited by the need for ultra-cold operating temperatures. Connecting several smaller processors could create larger, more computationally powerful quantum computers -- however doing so poses new challenges. Researchers have now demonstrated quantum entanglement between optical and microwave photons that could lay the foundation for such a future quantum network.
Published Robotic proxy brings remote users to life in real time



Researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.
Published A cocktail party of 3D-printed robot heads



Imagine a cocktail party full of 3D-printed, humanoid robots listening and talking to each other. That seemingly sci-fi scene is the goal of an augmented listening laboratory. With precise control over the simulated subjects, the researchers can adjust the parameters of the experiment and even set the machines in motion to simulate neck movements.
Published Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes



Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.
Published The future of data storage lies in DNA microcapsules



Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.
