Published Floating sea farms: A solution to feed the world and ensure fresh water by 2050



The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.
Published Magnetic whirls pave the way for energy-efficient computing


Researchers have been able to increase the diffusion of magnetic whirls, so called skyrmions, by a factor of ten.
Published AI can help write a message to a friend -- but don't do it


Using artificial intelligence applications to help craft a message to a friend is not a good idea -- at least if your friend finds out about the use of AI, a new study suggests.
Published 'Brainless' robot can navigate complex obstacles


Researchers who created a soft robot that could navigate simple mazes without human or computer direction have now built on that work, creating a 'brainless' soft robot that can navigate more complex and dynamic environments.
Published What do neurons, fireflies and dancing the Nutbush have in common?


Synchronicity is all around us, but it is poorly understood. Computer scientists have now developed new tools to understand how human and natural networks fall in and out of sync.
Published Online AI-based test for Parkinson's disease severity shows promising results


A new artificial intelligence tool can help people with Parkinson's disease remotely assess the severity of their symptoms within minutes. While expert neurologists performed slightly better than the AI model, the AI model outperformed the primary care physicians with UPDRS certification.
Published Fossil spines reveal deep sea's past



Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.
Published Researchers use AI to find new magnetic materials without critical elements


A team of scientists developed a new machine learning model for discovering critical-element-free permanent magnet materials based on the predicted Curie temperature of new material combinations.
Published Better cybersecurity with new material


Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published A system to keep cloud-based gamers in sync


A new technique can synchronize media streams from different networks to multiple devices with less than 10 milliseconds of delay. The technique was demonstrated on cloud gaming, but could also be applied in AR/VR applications.
Published New AI technology gives robot recognition skills a big lift


The day when robots can cook dinner, clear the kitchen table and empty the dishwasher is still a long way off. First, robots need to be able to recognize the many items of different sizes, shapes and brands in our homes. A team has now made a significant advance toward that technology with a robotic system that uses artificial intelligence to help robots better identify and remember objects.
Published Breathe! The shape-shifting ball that supports mental health


A soft ball designed to support mental health by 'personifying' breath has been invented by a computer science student.
Published Analog and digital: The best of both worlds in one energy-efficient system


We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary code, breaking the information into little bits (or bites). Researchers have revealed a pioneering technology that combines the potential of continuous analog processing with the precision of digital devices. By seamlessly integrating ultra-thin, two-dimensional semiconductors with ferroelectric materials, the research unveils a novel way to improve energy efficiency and add new functionalities in computing. The new configuration merges traditional digital logic with brain-like analog operations.
Published A lightweight wearable device helps users navigate with a tap on the wrist



Scientists have developed a fabric-based wearable device that 'taps' a user's wrist with pressurized air, silently helping them navigate to their destination. The study demonstrated that users correctly interpreted which direction the device was telling them to go an average of 87% of the time. Since the wearable embeds most of its control system within the fabric itself, using air instead of electronics, it can be built lighter and more compact than existing designs.
Published Sensors harnessing light give hope in rehabilitation


A research team overcomes limitations of conventional strain sensors using computer vision integrated optical sensors.
Published Computer scientists use AI to accelerate computing speed by thousands of times


A team of computer scientists recently unveiled a prize-winning Python profiler called Scalene. Programs written with Python are notoriously slow -- up to 60,000 times slower than code written in other programming languages -- and Scalene works to efficiently identify exactly where Python is lagging, allowing programmers to troubleshoot and streamline their code for higher performance.
Published Quantum computer unveils atomic dynamics of light-sensitive molecules


Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.
Published Brain signals transformed into speech through implants and AI


Researchers have succeeded in transforming brain signals into audible speech. By decoding signals from the brain through a combination of implants and AI, they were able to predict the words people wanted to say with an accuracy of 92 to 100%.
Published Pros and cons of ChatGPT plugin, Code Interpreter, in education, biology, health


Researchers see potential in educational settings for the newest official ChatGPT plugin, called Code Interpreter, they've found limitations for its use by scientists who work with biological data utilizing computational methods to prioritize targeted treatment for cancer and genetic disorders.
Published AI helps robots manipulate objects with their whole bodies


A new AI technique enables a robot to develop complex plans for manipulating an object using its entire hand, not just fingertips. This model can generate effective plans in about a minute using a standard laptop.
