Researchers have developed a groundbreaking electron paramagnetic resonance (EPR) sensor that fits on a microchip, enabling the detection of free radicals in food products even at extremely low concentrations. This innovative “EPR on a chip” (ERPoC) sensor, created by teams from Helmholtz-Zentrum Berlin (HZB) and the University of Stuttgart, is portable, affordable, and small enough to be tailored to specific industry needs. Initially, it will be used to monitor the quality of olive oil and beer.

“We are designing small, portable, and cost-effective EPR devices by integrating a microchip with permanent magnets, customized for various applications,” says Michele Segantini, a physicist from HZB who is nearing the completion of his PhD under Prof. Klaus Lips. Free radicals, highly reactive molecules that indicate spoilage, are difficult to detect. Traditional methods for detecting these molecules in food products require expensive EPR machines that are large and power-hungry, limiting their use.

Water contamination caused by chemicals used in modern technology is an escalating global issue. A recent study by the U.S. Centers for Disease Control found that 98% of people tested had detectable levels of PFAS—long-lasting “forever chemicals”—in their bloodstream. However, a new natural filtration material developed by MIT researchers may offer a solution. Made from silk and cellulose, this innovative filter can remove a range of persistent contaminants, including PFAS and heavy metals, while also boasting antimicrobial properties that prevent filter fouling.

The findings, published in ACS Nano, were led by MIT postdoc Yilin Zhang, civil and environmental engineering professor Benedetto Marelli, and their team. The material’s creation originated from Marelli’s lab, which initially sought to combat counterfeit seeds through silk nanofibrils. Zhang suggested the material’s potential for water filtration, leading to the addition of cellulose to the silk structure, enhancing its performance. This hybrid material has shown promise in lab tests, significantly outperforming traditional filters like activated carbon.

Researchers at Japan’s National Institute of Materials Science (NIMS) have developed a highly flexible alloy made of titanium and nickel that could revolutionize industries by enabling shape-shifting aircraft and ultra-strong artificial muscles. The alloy boasts the strength of steel while remaining as stretchable as rubber when subjected to environmental changes.

Shape-shifting aircraft have long been the stuff of science fiction, primarily due to the challenge of creating a material flexible enough for such transformations yet robust enough to withstand the stresses of flight. Balancing strength and flexibility has been a major obstacle for scientists, as increasing one often comes at the expense of the other. While a shape-shifting aircraft could lead to greater energy efficiency and faster travel, passenger safety remains paramount, requiring materials that do not compromise on durability.

LG Display, a global leader in display innovation, announced that it is showcasing its groundbreaking Stretchable displays at one of the world’s most anticipated fashion events—2025 S/S Seoul Fashion Week, held at Dongdaemun Design Plaza (DDP). These cutting-edge displays can be freely stretched, folded, and twisted, marking a major fusion of technology and fashion.

Debuting as part of futuristic clothing and bag concepts, LG Display’s Stretchable displays will be featured on the front of garments, sleeves, and clutch bags, designed by renowned Korean designers Youn-Hee Park of GREEDILOUS and Chung-Chung Lee of LIE. The models will showcase these revolutionary designs on the runway on September 5 and 7.

Hypermotive Limited, a UK-based leader in sustainable transport solutions, has unveiled the XM-1, a groundbreaking hydrogen fuel cell platform designed to revolutionize power generation in the maritime industry. Backed by Honda, this collaboration marks the Japanese automaker’s entry into hydrogen fuel cell technology in Europe.

As the transportation sector accounts for 20% of global CO2 emissions, efforts to reduce fossil fuel dependency have intensified. Electric vehicles (EVs) have led the way in reducing emissions for road-based and smaller vehicles. However, larger forms of transportation, like long-haul trucks and container ships, still rely heavily on fossil fuels due to their superior power density, ease of refueling, and global availability.
