Published Unleashing disordered rocksalt oxides as cathodes for rechargeable magnesium batteries



Researchers have made a groundbreaking advancement in battery technology, developing a novel cathode material for rechargeable magnesium batteries that enables efficient charging and discharging even at low temperatures.
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 New materials discovered for safe, high-performance solid-state lithium-ion batteries



All-solid-state lithium-ion batteries offer enhanced safety and energy density compared to liquid electrolyte counterparts, but face challenges like lower conductivity and insufficient electrode contact. In a recent study, scientists have discovered a stable, highly conductive lithium-ion conductor in the form of a pyrochlore-type oxyfluoride. This innovation addresses the need for non-sulfide solid electrolytes, offering higher conductivity and stability and paves the way for advanced all-solid-state lithium-ion batteries with improved performance and safety.
Published Are high-purity cathode materials truly necessary?



Researchers introduce a groundbreaking alternative to reduce secondary battery costs.
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 Implantable batteries can run on the body's own oxygen



From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and dampen pain. But batteries eventually run low and require invasive surgeries to replace. To address these challenges, researchers have devised an implantable battery that runs on oxygen in the body. The study shows in rats that the proof-of-concept design can deliver stable power and is compatible with the biological system.
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 New all-liquid iron flow battery for grid energy storage



A new iron-based aqueous flow battery shows promise for grid energy storage applications.
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 Crawfish could transfer ionic lithium from their environment into food chain



Lithium-ion rechargeable batteries are showing up in ever more devices, and the increasing use of this technology means more lithium is expected to find its way into the environment as a contaminant. In new research, a team has explored how this ion accumulates in a common Southern crustacean, the crawfish, with implications for the environment and public health.
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 Fast-charging lithium-sulphur batteries on the horizon



New research shows that the next generation of lithium-sulphur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case.
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 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 Revolutionary method developed for mass-producing polymer solid electrolytes



Scientists have unveiled a groundbreaking technique for mass-producing polymer solid electrolytes, crucial components in batteries.
