Published Can't find your phone? There's a robot for that



Engineers have discovered a new way to program robots to help people with dementia locate medicine, glasses, phones and other objects they need but have lost.
Published New priming method improves battery life, efficiency



Engineers have developed a readily scalable method to optimize a silicon anode priming method that increases lithium-ion battery performance by 22% to 44%.
Published Metal-filtering sponge removes lead from water



Engineers have developed a new sponge that can remove metals -- including toxic heavy metals like lead and critical metals like cobalt -- from contaminated water, leaving safe, drinkable water behind. In proof-of-concept experiments, the researchers tested their new sponge on a highly contaminated sample of tap water, containing more than 1 part per million of lead. With one use, the sponge filtered lead to below detectable levels.
Published Better than humans: Artificial intelligence in intensive care units



With the help of extensive data from intensive care units of various hospitals, an artificial intelligence was developed that provides suggestions for the treatment of people who require intensive care due to sepsis. Analyses show that artificial intelligence already surpasses the quality of human decisions. However, it is now important to also discuss the legal aspects of such methods.
Published Researcher uses artificial intelligence to discover new materials for advanced computing



Researchers have identified novel van der Waals (vdW) magnets using cutting-edge tools in artificial intelligence (AI). In particular, the team identified transition metal halide vdW materials with large magnetic moments that are predicted to be chemically stable using semi-supervised learning. These two-dimensional (2D) vdW magnets have potential applications in data storage, spintronics, and even quantum computing.
Published 'Super-resolution' imaging technology



Researchers describe developing a super-resolution imaging platform technology to improve understanding of how nanoparticles interact within cells.
Published Leaky-wave metasurfaces: A perfect interface between free-space and integrated optical systems



Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These are the first to demonstrate simultaneous control of all four optical degrees of freedom. Because they're so thin, transparent, and compatible with photonic integrated circuits, they can be used to improve optical displays, LIDAR, optical communications, and quantum optics.
Published The influence of AI on trust in human interaction



As AI becomes increasingly realistic, our trust in those with whom we communicate may be compromised. Researchers at the University of Gothenburg have examined how advanced AI systems impact our trust in the individuals we interact with.
Published QuanÂtum comÂputer in reverse gear



Large numbers can only be factorized with a great deal of computational effort. Physicists are now providing a blueprint for a new type of quantum computer to solve the factorization problem, which is a cornerstone of modern cryptography.
Published Engineers tap into good vibrations to power the Internet of Things



In a world hungry for clean energy, engineers have created a new material that converts the simple mechanical vibrations all around us into electricity to power sensors in everything from pacemakers to spacecraft.
Published Deep neural network provides robust detection of disease biomarkers in real time



A lab has developed a deep neural network that improves the accuracy of their unique devices for detecting pathogen biomarkers.
Published A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads



It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.
Published Joyful music could be a game changer for virtual reality headaches



Listening to music could reduce the dizziness, nausea and headaches virtual reality users might experience after using digital devices, research suggests. Cybersickness -- a type of motion sickness from virtual reality experiences such as computer games -- significantly reduces when joyful music is part of the immersive experience, the study found. The intensity of the nausea-related symptoms of cybersickness was also found to substantially decrease with both joyful and calming music.
Published Self-folding origami machines powered by chemical reaction



Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.
Published Quantum entanglement of photons doubles microscope resolution



Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Published Toys demonstrate how biological machines move



By connecting small self-propelling toys in a chain, researchers have found the key to studying the movement of microscopic organisms and molecular motors inside our cells.
Published Sensor enables high-fidelity input from everyday objects, human body



Couches, tables, sleeves and more can turn into a high-fidelity input device for computers using a new sensing system.
Published Lithography-free photonic chip offers speed and accuracy for artificial intelligence



Researchers have created a photonic device that provides programmable on-chip information processing without lithography, offering the speed of photonics augmented by superior accuracy and flexibility for AI applications. Achieving unparalleled control of light, this device consists of spatially distributed optical gain and loss. Lasers cast light directly on a semiconductor wafer, without the need for defined lithographic pathways.
Published Brain activity decoder can reveal stories in people's minds



A new AI-based system called a semantic decoder can translate a person's brain activity -- while listening to a story or silently imagining telling a story -- into a continuous stream of text. Unlike other thought decoding systems in development, this system does not require subjects to have surgical implants, making the process noninvasive.
Published Engineers 'grow' atomically thin transistors on top of computer chips



A new method enables 2D-material semiconductor transistors to be directly integrated onto a fully fabricated 8-inch silicon wafer, which could enable a new generation of transistor technology, denser device integration, new circuit architectures, and more powerful chips.
