Published Star Trek's Holodeck recreated using ChatGPT and video game assets



Star Trek's Holodeck is no longer just science fiction. Using AI, engineers have created a tool that can generate 3D environments, prompted by everyday language.
Published Breakthrough promises secure quantum computing at home



The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published Engineers design soft and flexible 'skeletons' for muscle-powered robots



Engineers designed modular, spring-like devices to maximize the work of live muscle fibers so they can be harnessed to power biohybrid robots.
Published Protecting art and passwords with biochemistry



A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers.
Published 'Smart swarms' of tiny robots inspired by natural herd mentality



Researchers gave nanorobots a trait called adaptive time delay, which allows them to better work together.
Published AI writing, illustration emits hundreds of times less carbon than humans, study finds



A group of scholars calculated the amount of energy used by AI tools for the tasks of writing and illustrating and compared it to the average amount of energy humans use for the same processes. Their results showed artificial intelligence results in hundreds of times less carbon emissions than humans. This does not mean, however, that AI can or should replace humans in those tasks, simply that its energy usage is less. The better approach is a partnership between humans and AI, the authors write.
Published 100 kilometers of quantum-encrypted transfer



Researchers have taken a big step towards securing information against hacking. They have succeeded in using quantum encryption to securely transfer information 100 kilometers via fiber optic cable -- roughly equivalent to the distance between Oxford and London.
Published Study uses artificial intelligence to show how personality influences the expression of our genes



An international study using artificial intelligence has shown that our personalities alter the expression of our genes. The findings shed new light on the long-standing mystery of how the mind and body interact.
Published Robot, can you say 'cheese'?



What would you do if you walked up to a robot with a human-like head and it smiled at you first? You'd likely smile back and perhaps feel the two of you were genuinely interacting. But how does a robot know how to do this? Or a better question, how does it know to get you to smile back?
Published Micro-Lisa! Making a mark with novel nano-scale laser writing



High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components. Now researchers have discovered a light-responsive, inexpensive sulfur-derived polymer is receptive to low power, visible light lasers -- promising a more affordable and safer production method in nanotech, chemical science and patterning surfaces in biological applications.
Published The world is one step closer to secure quantum communication on a global scale



Researchers have brought together two Nobel prize-winning research concepts to advance the field of quantum communication. Scientists can now efficiently produce nearly perfect entangled photon pairs from quantum dot sources.
Published Robotic metamaterial: An endless domino effect



If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.
Published Brain-inspired wireless system to gather data from salt-sized sensors



In a new study, researchers describe a novel approach for a wireless communication network that can efficiently transmit, receive and decode data from thousands of microelectronic chips that are each no larger than a grain of salt.
Published Artificial nanofluidic synapses can store computational memory



In a step toward nanofluidic-based neuromorphic -- or brain-inspired -- computing, engineers have succeeded in executing a logic operation by connecting two chips that use ions, rather than electrons, to process data.
Published Backyard insect inspires invisibility devices, next gen tech



Leafhoppers, a common backyard insect, secrete and coat themselves in tiny mysterious particles that could provide both the inspiration and the instructions for next-generation technology, according to a new study. In a first, the team precisely replicated the complex geometry of these particles, called brochosomes, and elucidated a better understanding of how they absorb both visible and ultraviolet light.
Published Two artificial intelligences talk to each other



Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI). A team has succeeded in modelling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them to a 'sister' AI, which in turn performed them.
Published Where quantum computers can score



The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a team has shown that a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods.
Published Holographic message encoded in simple plastic



Important data can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists show. Holography can be done quite easily: A 3D printer can be used to produce a panel from normal plastic in which a QR code can be stored, for example. The message is read using terahertz rays -- electromagnetic radiation that is invisible to the human eye.
Published New technique helps AI tell when humans are lying



Researchers have developed a new training tool to help artificial intelligence (AI) programs better account for the fact that humans don't always tell the truth when providing personal information. The new tool was developed for use in contexts when humans have an economic incentive to lie, such as applying for a mortgage or trying to lower their insurance premiums.
Published Advanced army robots more likely to be blamed for deaths



Advanced killer robots are more likely to blamed for civilian deaths than military machines, new research has revealed. The study shows that high-tech bots will be held more responsible for fatalities in identical incidents.
