Published AI helps show how the brain's fluids flow



A new, AI-based technique for measuring fluid flow in the brain could lead to treatments for diseases such as Alzheimer's.
Published Hybrid AI-powered computer vision combines physics and big data



Researchers have laid out a new approach to enhance artificial intelligence-powered computer vision technologies by adding physics-based awareness to data-driven techniques. The study offered an overview of a hybrid methodology designed to improve how AI-based machinery sense, interact and respond to its environment in real time -- as in how autonomous vehicles move and maneuver, or how robots use the improved technology to carry out precision actions.
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 The chatbot will see you now



Results from a study of the use of a chatbot in the consent process show that it encourages inclusivity, and leads to faster completion and high levels of understanding. Whereas the traditional method of consenting does not have a mechanism to verify understanding objectively, the chat-based method can test comprehension. It does not allow users who do not show understanding to give consent; rather, it puts them in touch with a genetic counsellor to figure out why knowledge transmission did not occur. It could be accessed at any time; more than half the patients interacted with the bot during these times, and this shows its utility in decreasing the barriers to entry to trials.
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 MethaneMapper is poised to solve the problem of underreported methane emissions



MethaneMapper is an artificial intelligence-powered hyperspectral imaging tool that researchers have developed to detect real-time methane emissions and trace them to their sources. The tool works by processing hyperspectral data gathered during overhead, airborne scans of the target area.
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 Sponge makes robotic device a soft touch



A simple sponge has improved how robots grasp, scientists have found.
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 Shining a light on neuromorphic computing



AI, machine learning, and ChatGPT may be relatively new buzzwords in the public domain, but developing a computer that functions like the human brain and nervous system -- both hardware and software combined -- has been a decades-long challenge. Engineers are exploring how optical "memristors" may be a key to developing neuromorphic computing.
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 Quantum computers are better at guessing, new study demonstrates



Researchers have demonstrated a quantum speedup over the most efficient classical computer algorithm possible for what is believed to be the first time. The accomplishment was performed on an IBM Montreal Quantum Falcon r4 27-qubit device.
Published New method improves efficiency of 'vision transformer' AI systems



Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both computing power requirements and decision-making transparency. Researchers have now developed a new methodology that addresses both challenges, while also improving the ViT's ability to identify, classify and segment objects in images.
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.
