Published Animal brain inspired AI game changer for autonomous robots



A team of researchers has developed a drone that flies autonomously using neuromorphic image processing and control based on the workings of animal brains. Animal brains use less data and energy compared to current deep neural networks running on GPUs (graphic chips). Neuromorphic processors are therefore very suitable for small drones because they don't need heavy and large hardware and batteries. The results are extraordinary: during flight the drone's deep neural network processes data up to 64 times faster and consumes three times less energy than when running on a GPU. Further developments of this technology may enable the leap for drones to become as small, agile, and smart as flying insects or birds.
Published Robots' and prosthetic hands' sense of touch could be as fast as humans



Research could pave the way for a prosthetic hand and robot to be able to feel touch like a human hand. The technology could also be used to help restore lost functionality to patients after a stroke.
Published A simple quantum internet with significant possibilities



It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible. That's exactly what physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world's longest fiber distance between two quantum memory nodes to date.
Published Virtual reality becomes more engaging when designers use cinematic tools



Cinematography techniques can significantly increase user engagement with virtual environments and, in particular, the aesthetic appeal of what users see in virtual reality.
Published Coming out to a chatbot?



Today, there are dozens of large language model (LLM) chatbots aimed at mental health care -- addressing everything from loneliness among seniors to anxiety and depression in teens. But the efficacy of these apps is unclear. Even more unclear is how well these apps work in supporting specific, marginalized groups like LGBTQ+ communities.
Published Cats purrfectly demonstrate what it takes to trust robots



Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.
Published AI systems are already skilled at deceiving and manipulating humans



Many artificial intelligence (AI) systems have already learned how to deceive humans, even systems that have been trained to be helpful and honest. Researchers describe the risks of deception by AI systems and call for governments to develop strong regulations to address this issue as soon as possible.
Published Good vibrations: New tech may lead to smaller, more powerful wireless devices



What if your earbuds could do everything your smartphone can, but better? A new class of synthetic materials could allow for smaller devices that use less power.
Published A better way to control shape-shifting soft robots



A new machine-learning technique can train and control a reconfigurable soft robot that can dynamically change its shape to complete a task. The researchers also built a simulator that can evaluate control algorithms for shape-shifting soft robots.
Published Generative AI that imitates human motion



Walking and running is notoriously difficult to recreate in robots. Now, a group of researchers has overcome some of these challenges by creating an innovative method that employs central pattern generators -- neural circuits located in the spinal cord that generate rhythmic patterns of muscle activity -- with deep reinforcement learning. The method not only imitates walking and running motions but also generates movements for frequencies where motion data is absent, enables smooth transition movements from walking to running, and allows for adapting to environments with unstable surfaces.
Published Discover optimal conditions for mass production of ultraviolet holograms



Scientists delve into the composition of nanocomposites for ultraviolet metasurface fabrication.
Published 'Digital afterlife': Call for safeguards to prevent unwanted 'hauntings' by AI chatbots of dead loved ones



Researchers lay out the need for design safety protocols that prevent the emerging 'digital afterlife industry' causing social and psychological harm.
Published Stilling the quantum dance of atoms



Researchers have discovered a way to stop the quantum dance of atoms 'seen' by electrons in carbon-based organic molecules. This development will help improve the performance of light emitting molecules used in displays and bio-medical imaging.
Published Caterbot? Robatapillar? It crawls with ease through loops and bends



Engineers created a catapillar-shaped robot that splits into segments and reassembles, hauls cargo, and crawls through twisting courses.
Published VR may pose privacy risks for kids: A new study finds parents aren't as worried as they should be



New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using parental controls built into the apps.
Published Biomechanical dataset for badminton performance analysis



In the sports industry, player data collection aids in personalized training feedback. Researchers have now gathered a detailed dataset and laid the foundation for delivering coaching assistance and feedback through the same. Utilizing wearable sensors and machine learning, their dataset offers real-time feedback and optimized movement suggestions. With over 7,763 badminton swings analyzed, stroke quality assessment offers valuable insights, making badminton training more accessible and affordable.
Published Stretchable e-skin could give robots human-level touch sensitivity



A stretchy electronic skin could equip robots and other devices with the same softness and touch sensitivity as human skin, opening up new possibilities to perform tasks that require a great deal of precision and control of force.
Published Random robots are more reliable



New algorithm encourages robots to move more randomly to collect more diverse data for learning. In tests, robots started with no knowledge and then learned and correctly performed tasks within a single attempt. New model could improve safety and practicality of self-driving cars, delivery drones and more.
Published Significant new discovery in teleportation research -- Noise can improve the quality of quantum teleportation



Researchers succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state.
Published Unveiling a polarized world -- in a single shot



Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock the vast potential of polarization imaging for a range of existing and new applications, including biomedical imaging, augmented and virtual reality systems and smart phones.
