A groundbreaking achievement in sensor technology has emerged from the Energy & Environmental Materials Research Division at the Korea Institute of Materials Science (KIMS). Led by Dr. Jongwon Yoon, Dr. Jeongdae Kwon, and Dr. Yonghoon Kim, the research team has developed the world’s first ammonia (NH₃) gas sensor built on a copper bromide (CuBr) film, manufactured through a low-temperature, solution-based process.

This innovation marks a significant leap forward in gas sensing technology. The new sensor is flexible, highly sensitive, selectively responsive to ammonia, and cost-effective to produce—opening the door for widespread use in fields like environmental monitoring, industrial safety, and medical diagnostics.

Researchers at the University of Glasgow have developed an innovative computer system that could revolutionize search and rescue missions in remote areas. By analyzing patterns in how real people behave when lost, this new method predicts the most likely locations where missing individuals might be found—without relying on guesswork or chance.

The technology, led by PhD candidate Jan-Hendrik Ewers from the James Watt School of Engineering, uses artificial intelligence to simulate the actions of lost individuals. These “simulated agents” behave according to psychological models and real-world data, factoring in needs like finding water, shelter, paths, or roads. The result is a detailed heat map showing high-probability search areas across a given landscape.

Researchers at Cornell University have developed a groundbreaking device that uses two of Earth’s most abundant resources—sunlight and seawater—to create carbon-free green hydrogen and clean drinking water simultaneously. This compact invention, known as the hybrid solar distillation-water electrolysis system (HSD-WE), measures just 10 by 10 centimeters and could significantly impact the future of sustainable energy and water access.

Traditionally, producing green hydrogen involves splitting pure water into hydrogen and oxygen through electrolysis, a process that requires vast amounts of clean water and is often energy-intensive and costly. In contrast, Cornell’s device turns the limitations of solar panels—specifically their low efficiency—into an advantage.

Every year, more than 400 million tonnes of plastic are produced worldwide. A significant portion of that—about five percent—finds its way into rivers and oceans, either from general waste or directly through the fishing industry. Regardless of whether it breaks down into microplastics or remains intact, plastic pollution continues to pose a serious environmental and health threat to ecosystems and communities around the world.

In response to this growing problem, researchers have introduced a promising new material called transparent paperboard, or tPB. Designed to look and function like plastic, tPB offers the added benefits of being biodegradable, recyclable, and made entirely from cellulose—the same plant-based material found in traditional paper. It provides a sustainable alternative to plastic without compromising performance.

In the race toward carbon neutrality, innovation is everything—and a research team in Japan may have just taken a major leap forward. Scientists from Tohoku University, Hokkaido University, and AZUL Energy have developed a rapid, cost-effective method to convert carbon dioxide (CO₂) into carbon monoxide (CO)—a crucial building block for synthetic fuels.

This method dramatically reduces processing time from 24 hours to just 15 minutes, signaling a potential game-changer for carbon capture and utilization (CCU) technologies.

In a groundbreaking discovery, scientists in the U.S. have identified a previously unknown group of microbes thriving deep underground—up to 70 feet beneath the surface. This newly classified microbial phylum, named CSP1-3, not only survives in these harsh subterranean conditions but also plays a significant role in purifying groundwater, with exciting implications for future water filtration technologies.

The study, led by Dr. James Tiedje, university distinguished professor emeritus and director of the Center for Microbial Ecology at Michigan State University (MSU), uncovered CSP1-3 in soil samples collected from Iowa in the U.S. and China. Both sites belong to Earth’s Critical Zone, a vast region that stretches from the tree canopy down through soil layers to bedrock, sometimes extending as deep as 700 feet.
