Imagine wearing a thin flexible sticker that can turn your hand or finger movement into communication without you having to say a word or tap a touch screen. Researchers have developed a new type of wearable sensor that can accomplish this futuristic feat and could open new possibilities for rehabilitation applications and help those with disabilities to communicate more easily.

Research published in the International Journal of Ad Hoc and Ubiquitous Computingintroduces a new approach to tackling the challenges posed by deepfake technology, which generates manipulated media content that closely resembles authentic footage.

In our technologically dependent society, the mobility, dependability, and safety of our devices—including phones and laptops—are critical. Just as important is our ability to easily charge and recharge these devices so they are available when we need them.

A NIMS research team has developed a new technique to image grain boundaries obstructing lithium-ion migration in solid-state batteries—a promising type of next-generation battery.

There's a lot of research about moving away from carbon as an energy source, but what if, instead, the carbon that is being used is applied to its full capacity?

Spacetime is a conceptual model that fuses the three dimensions of space (length, width, and breadth) with the fourth dimension of time. By doing so, a four-dimensional geometric object is created. Researchers have recently used a similar way of thinking to study AI environments, leading to a unique reframing of AI problems in geometric terms.

Low-income households in the United States are bearing an energy burden that is three times that of the average household, according to the U.S. Department of Energy. In total, more than 46 million U.S. households carry a significant energy burden—meaning they pay more than 6% of their gross income for basic energy expenses such as cooling and heating their homes.

As the climate crisis escalates, there are urgent and difficult choices that need to be made to drastically reduce our carbon emissions before more irreparable damage is done.

Researchers at the University of Konstanz have successfully filmed the operations of extremely fast electronic circuitry in an electron microscope at a bandwidth of tens of terahertz. The study is published in Nature Communications.

A Jeff Koons statue is on the Moon.

A radical new type of touch sensor for robotics and other bio-mimicking (bionic) applications is so sensitive it works even without direct contact between the sensor and the objects being detected. It senses interference in the electric field between an object and the sensor, at up to 100 millimeters from the object.

AI decision-making is now common in self-driving cars, patient diagnosis and legal consultation, and it needs to be safe and trustworthy. Researchers have been trying to demystify complex AI models by developing interpretable and transparent models, collectively known as explainable AI methods or explainable AI (XAI) methods. A research team offered their insight specifically into audio XAI models in a review article published in Intelligent Computing.

Uppsala University is the new world record holder for electrical energy generation from copper indium gallium selenide (CIGS) solar cells. The new world record is 23.64% efficiency. The measurement was made by an independent institute, and the results are published in Nature Energy.

Biomimetic robots, which mimic the movements and biological functions of living organisms, are a fascinating area of research that can not only lead to more efficient robots but also serve as a platform for understanding muscle biology.

In a recent class session devoted to reviewing the components of a monogastric digestive system, Alexandra Else-Keller reminded an animal science student how to position her fingers as they examined how the colon, stomach, and gallbladder nestle together.

A collaboration between Queen Mary University of London, University College London (UCL), Rolls-Royce, and a team of international researchers has unlocked the secrets of pore evolution in directed energy deposition (DED) additive manufacturing. Their findings, published in Nature Communications, pave the way for safer and more efficient production of high-value components across diverse industries.

Power cuts can be caused by heavy snow and icing, as well as lightning strikes and strong winds bringing down power lines. Together with more extreme weather events, Norway is also facing a major power supply deficit. So what can we do to avoid a total electricity crisis?

Copper smelting is a major source of copper production, generating significant amounts of slag. In 2022, China produced over 11,000 kilotons of refined copper, leading to 2.2 to 3 tons of slag per ton of copper produced. This slag contains valuable metals like copper (0.5%–6%), lead (0.2%–0.6%), and zinc (1%–5.5%), which are often not recovered, resulting in resource waste and environmental hazards from leaked toxic ions.

To become carbon neutral by 2060, as mandated by President Xi Jinping, China will have to build eight to 10 times more wind and solar power installations than currently exist in the country. Reaching carbon neutrality will also require major construction of transmission lines.

Imagine a world where your smartphone can detect your mood just by the way you type a message or the tone of your voice. Picture a car that adjusts its music playlist based on your stress levels during rush hour traffic. These scenarios are not just futuristic fantasies.
