Thermal Camera Senses Breathing To Improve Exercise Calorie Estimates
The estimates of calories burned made by smartphones, smartwatches and other wearable devices vary wildly. That's because these devices lack the sensors required to gather all the information they need to make accurate estimates. But new work by researchers at Carnegie Mellon University and the Indian Institute of Technology (IIT) Gandhinagar shows that adding an inexpensive thermal camera to these devices could substantially improve accuracy.

Machine learning enables viability of vertical-axis wind turbines
Machine learning enables viability of vertical-axis wind turbines
Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind. If you imagine an industrial wind turbine, you likely picture the windmill design, technically known as a horizontal-axis wind turbine (HAWT).

App can help people reduce their alcohol intake
App can help people reduce their alcohol intake
A free smartphone app, Drink Less, can help people who would benefit most from reducing their alcohol consumption to do so successfully, according to a large randomised controlled trial led by UCL researchers. The study, published in eClinicalMedicine funded by the National Institute for Health and Care Research (NIHR) , found that people randomly recommended to use the Drink Less app reduced their drinking by 39 units a week at six months - two more units a week on average than a control group who were referred to standard NHS advice.

Large language models use a surprisingly simple mechanism to retrieve some stored knowledge
Researchers demonstrate a technique that can be used to probe a model to see what it knows about new subjects. Large language models, such as those that power popular artificial intelligence chatbots like ChatGPT, are incredibly complex. Even though these models are being used as tools in many areas, such as customer support, code generation, and language translation, scientists still don't fully grasp how they work.

How discarded smartphones can help decarbonize the building sector
How discarded smartphones can help decarbonize the building sector
Automated building systems offer a great potential for reducing the energy consumption of properties. Studies on such systems show that optimized solutions can reduce the energy requirements of buildings by around 30 percent on average. In order to avoid the necessity to produce new and emission-heavy computer chips, Empa researcher Hanmin Cai is currently investigating the extent to which damaged smartphones that are no longer used could perform these control and maintenance tasks.

UC3M gets Fundación BBVA research project to analyse the relationship between friendship and culture
The Universidad Carlos III de Madrid (UC3M) is coordinating one of the five BBVA Foundation's Fundamentals Programme's innovative research projects to explore core issues in basic science. Specifically, the UC3M project, in which research staff from the Universitat Autónoma de Barcelona (UAB) and the University of Florida (UF) in the USA are also participating, will analyse the mutual dependence between social relations and cultural characteristics.

Controlling chaotic turbulence to make ’cat-coat’ patterns in fluids
Researchers from TU/e and the University of Chicago discovered how to manipulate turbulent flows to create regular patterns like those seen in the tabby coat pattern of a cat. The new research has been published in Nature. Controlling the chaos of a turbulent flow to make regular patterns sounds like a contradiction in every sense of the word.

Verifying the Work of Quantum Computers
Quantum computers of the future may ultimately outperform their classical counterparts to solve intractable problems in computer science, medicine, business, chemistry, physics, and other fields. But the machines are not there yet: They are riddled with inherent errors, which researchers are actively working to reduce.

AI can now detect COVID-19 in lung ultrasound images
AI can now detect COVID-19 in lung ultrasound images
An automated detection tool developed by Johns Hopkins researchers could help ER doctors diagnose patients quickly and accurately Artificial intelligence can spot COVID-19 in lung ultrasound images much like facial recognition software can spot a face in a crowd, new research shows. The findings boost AI-driven medical diagnostics and bring health care professionals closer to being able to quickly diagnose patients with COVID-19 and other pulmonary diseases with algorithms that comb through ultrasound images to identify signs of disease.

Redefining Quantum Machine Learning
New study from team of quantum physicists at Freie Universität Berlin challenges traditional understanding of quantum machine learning Machine learning is a branch of artificial intelligence (AI) and computer science that focuses on the use of data and algorithms to allow computers to learn without explicitly being programmed.

Does Artificial Intelligence work in English?
Does Artificial Intelligence work in English?
Researchers have shown that large language models primarily trained on English text seem to use English internally, even when they are prompted in another language. As AI increasingly runs our lives, this may have important consequences regarding linguistic and cultural bias. Large language models (LLMs) including Open AI's ChatGPT and Google's Gemini have taken the world by storm, surprising with their ability to understand and respond to users with seemingly natural speech.

Researchers help robots navigate efficiently in uncertain environments
A new algorithm reduces travel time by identifying shortcuts a robot could take on the way to its destination. If a robot traveling to a destination has just two possible paths, it needs only to compare the routes' travel time and probability of success. But if the robot is traversing a complex environment with many possible paths, choosing the best route amid so much uncertainty can quickly become an intractable problem.

More precise understanding of dark energy achieved using AI
More precise understanding of dark energy achieved using AI
A UCL-led research team has used artificial intelligence (AI) techniques to infer the influence and properties of dark energy more precisely from a map of dark and visible matter in the Universe covering the last seven billion years. The study, carried out by the Dark Energy Survey collaboration, doubled the precision at which key characteristics of the Universe, including the overall density of dark energy, could be inferred from the map.

Researchers enhance peripheral vision in AI models
Researchers enhance peripheral vision in AI models
By enabling models to see the world more like humans do, the work could help improve driver safety and shed light on human behavior. Peripheral vision enables humans to see shapes that aren't directly in our line of sight, albeit with less detail. This ability expands our field of vision and can be helpful in many situations, such as detecting a vehicle approaching our car from the side.

Method rapidly verifies that a robot will avoid collisions
Faster and more accurate than some alternatives, this approach could be useful for robots that interact with humans or work in tight spaces. Before a robot can grab dishes off a shelf to set the table, it must ensure its gripper and arm won't crash into anything and potentially shatter the fine china.

Can you tell AI-generated people from real ones?
Research shows survey participants duped by AI-generated images nearly 40 per cent of the time If you recently had trouble figuring out if an image of a person is real or generated through artificial intelligence (AI), you're not alone. A new study from University of Waterloo researchers found that people had more difficulty than was expected distinguishing who is a real person and who is artificially generated.
