A team of researchers led by Mount Sinai has significantly advanced an artificial intelligence (AI)-powered algorithmdesigned to analyze video recordings from clinical sleep tests, enhancing the accuracy of diagnosing REM Sleep Behavior Disorder (RBD)—a common sleep disorder affecting over 80 million people worldwide. This breakthrough, published in the journal Annals of Neurology on January 9, promises to improve diagnostic precision and aid early detection of Parkinson’s disease and dementia, conditions often heralded by RBD.

RBD is characterized by abnormal movements or the acting out of dreams during the REM phase of sleep. When it occurs in otherwise healthy individuals, it is referred to as “isolated RBD,” which affects more than one million people in the United States alone. Nearly all cases of isolated RBD are early indicators of neurodegenerative conditions such as Parkinson’s disease or dementia.

A research team led by Prof. Wan Yinhua at the Institute of Process Engineering (IPE), Chinese Academy of Sciences, has developed a groundbreaking mix-charged nanofiltration (NF) membrane that promises to revolutionize wastewater treatment, especially for high-salinity organic waste. This novel membrane, featuring a horizontal charge distribution, exhibits exceptional performance in salt permeation, organic matter retention, and antifouling properties, making it an ideal solution for treating complex, high-salinity wastewater.

The findings were published in Environmental Science & Technology on January 7, shedding light on a new approach to overcoming the limitations of traditional NF membranes in wastewater treatment.

Imagine a device that could identify mechanical damage in apples before bruising appears, detect diseases through a patient’s breath, monitor food freshness in real time across entire supply chains, and even sniff out hazardous gases in industrial settings—all using technology already found in your smartphone. Researchers at the Norwegian University of Science and Technology (NTNU) have developed such a device: a groundbreaking electronic nose that uses a single sensor to perform tasks that typically require hundreds of sensors. This innovative technology, known as the “Ant-nose,” could revolutionize industries ranging from food safety to environmental monitoring, offering a simpler and more affordable alternative to existing systems.

The Ant-nose uses a familiar principle—antenna technology, the same technology that powers wireless communication in devices like smartphones and computers—to create an artificial sense of smell. Unlike traditional electronic noses, which often require large arrays of specialized sensors, the Ant-nose achieves its remarkable sensitivity with a single antenna and a single type of coating. This simplicity dramatically reduces both cost and power consumption while maintaining high performance.

As part of NASA’s Artemis campaign, a cutting-edge X-ray imager, the Lunar Environment Heliospheric X-ray Imager (LEXI), is heading to the Moon to capture the first global images of Earth’s magnetic field, which protects our planet from harmful solar radiation. LEXI is one of 10 scientific payloads onboard the upcoming lunar mission, set to launch from Kennedy Space Center in Florida no earlier than mid-January. The payload will ride aboard Firefly Aerospace’s Blue Ghost Lander under NASA’s Commercial Lunar Payload Services (CLPS) initiative.

LEXI’s primary mission is to support NASA’s understanding of how Earth’s magnetosphere—its magnetic shield—responds to space weather, which is driven by solar activity. By taking detailed X-ray images of this protective barrier, the instrument will provide insights into the dynamic processes that shape our planet’s interaction with the solar wind and other cosmic forces.

Imagine a world so minuscule it challenges the limits of human perception — the nanoscale. To visualize this, consider shrinking a single strand of human hair a million times over. In this incredibly tiny realm, atoms and molecules govern a universe of properties and behaviors that are largely uncharted — until now.

Researchers Deepak Singh and Carsten Ullrich, along with their teams of students and postdoctoral fellows at the University of Missouri’s College of Arts and Science, have made a groundbreaking discovery: the identification of a new type of quasiparticle present in all magnetic materials, regardless of their strength or temperature. This discovery opens up a new frontier in our understanding of magnetism and could revolutionize multiple fields of technology.

Voyant Photonics has officially launched its Carbon FMCW lidar sensor, a cutting-edge solution designed to provide affordable, high-performance lidar on a chip. This new sensor, developed for applications in industrial automation, robotics, and security, offers solid-state beam steering and high-resolution, millimeter-precision detection. The company aims to push the boundaries of machine perception with a sensor that delivers advanced capabilities at a disruptive price point.

At the heart of the Carbon sensor is a silicon photonic chip that is small enough to fit on a fingernail. Despite its compact size, the Carbon sensor offers high-resolution, real-time object detection and the ability to perform static and dynamic segmentation at distances of up to 200 meters (656 feet). Voyant integrated optics directly onto the lidar photonic integrated circuit (PIC), which allows for better performance at a fraction of the cost of traditional lidar technologies.

A comprehensive survey across 143 countries has highlighted how well various nations are equipped to support the world’s rapidly aging population, particularly in terms of well-being, equity, and security. As the global population ages, some countries are more prepared than others to handle the challenges and opportunities this demographic shift presents.

The aging of the world’s population is largely seen as a success story, reflecting advances in healthcare, medicine, and public health. A look back at 1950 reveals that the chances of a baby born in a high-income country surviving to 90 were just 4.8%. Today, that number has risen to 26.7%, with projections estimating that 50% of babies born today in high-income countries will reach that milestone by 2060. But with this longer life expectancy comes the question: Is the world socially and economically ready for an aging population?

Hearview glasses are a groundbreaking piece of technology designed to help those with hearing impairments stay connected in real-time. The glasses connect wirelessly to a smartphone, which runs the Hearview app. This app listens to conversations around the user, transcribes speech into text using artificial intelligence, and displays the transcribed words on a tiny, see-through screen built into the glasses.

The system supports 13 languages and, while there is a slight delay in transcription, this doesn’t pose a major issue, especially if the user cannot hear the spoken words directly. For many, the real-time text display offers a smooth and accessible way to engage in conversations.

In 2022, AVL RACETECH, the motorsport division of AVL, unveiled a revolutionary prototype—a hydrogen-powered internal combustion engine (H₂-ICE) that is set to change the future of racing and automotive technology. This 2-liter turbocharged engine, designed entirely in-house by AVL RACETECH, marks a significant leap forward in motorsport innovation. The engine not only runs on hydrogen but also incorporates advanced water injection technology, pushing the boundaries of performance while contributing to the shift toward sustainable energy solutions in racing.

Unlike conventional hydrogen engines that operate with a lean-burn approach—often limiting their performance—AVL RACETECH’s hydrogen internal combustion engine uses a slightly lean-burn technique. This results in a higher power output, achieving an impressive 150 kW per liter. This performance level places the engine on par with high-performance racing engines that are close to production specifications, showcasing the potential of hydrogen as a viable fuel for motorsport.

Researchers from the Institute of Science Tokyo have made a groundbreaking discovery: in-plane magnetic fields induce an anomalous Hall effect in EuCd₂Sb₂ films. By studying how these fields alter the material’s electronic structure, the team uncovered a significant in-plane anomalous Hall effect. This finding opens new avenues for controlling electronic transport in magnetic fields, with exciting potential applications in magnetic sensors.

The Hall effect, a well-known phenomenon in materials science, occurs when an electric current in a material is subjected to a magnetic field, creating a voltage that is perpendicular to both the current and the field. While much research has been conducted on the Hall effect under out-of-plane magnetic fields, the effects of in-plane magnetic fields have been less explored. Recently, however, in-plane magnetic fields have garnered increasing attention due to their potential to unlock new material behaviors, particularly in materials with unique electronic band structures, like EuCd₂Sb₂.
