For the first time, researchers have measured PFAS levels in health care workers — and the findings were surprising. The study reveals elevated concentrations not only in firefighters but also in medical professionals, pointing to previously overlooked occupational exposure risks.

pH measurements are vital for maintaining water quality, significantly influenced by the pH sensor's performance. This article outlines a step-by-step guide for calibrating a pH sensor using three buffer solutions (pH 4.01, 7.00, and 9.21) to achieve reliable results. Regular calibration is crucial for ensuring consistent and accurate readings across various applications, thereby enhancing decision-making in research and environmental monitoring.

A new paper in Nicotine and Tobacco Research, published by Oxford University Press, finds that today’s pod-style electronic cigarette devices are more addictive than nicotine gum, indicating that such devices have a very high potential for abuse.

Each spring, thousands of frogs and salamanders face deadly road crossings on their way to breed — but a small Vermont town shows there’s a better way. A study reveals that simple wildlife tunnels can cut amphibian deaths by over 80 %, offering hope for both local biodiversity and smarter infrastructure planning.

Can construction waste become the foundation of sustainable cities? A new study from Japan reveals how a geopolymer solidifier made from recycled glass and building byproducts could replace carbon-intensive cement, turning landfill-bound waste into a powerful tool for green infrastructure.

A research team at Rutgers University has discovered a new class of materials called intercrystals — atom-thin structures with tunable electronic properties. Formed by twisting layers of graphene and boron nitride, these materials could transform electronics, quantum computing, and sustainable tech by harnessing geometry at the atomic scale.

For over five centuries, Leonardo Da Vinci has been celebrated as a visionary artist, scientist, and inventor, known for his extraordinary talent and groundbreaking experiments. Now, an international collaboration known as the Leonardo DNA Project is closer than ever to uncovering the biological secrets of the greatest genius of the Renaissance.

Neurons deep in the brain not only help to initiate movement — they also actively suppress it, and with astonishing precision. This is the conclusion of a new study by researchers at the University of Basel and the Friedrich Miescher Institute for Biomedical Research (FMI), published in the journal Nature. The findings are especially relevant for better understanding neurological disorders such as Parkinson’s disease.

Scientists have developed contact lenses that grant infrared vision to humans and mice — without batteries or implants. Using light-converting nanoparticles, the lenses allow wearers to see both visible and near-infrared light, opening up new possibilities for night vision, encrypted communication, and even color blindness correction.

In the fight against superbugs and future pandemics, a surprising new weapon has emerged: hydrogen boride nanosheets. These transparent coatings kill viruses, bacteria, and fungi within minutes — no light needed. Now, researchers in Japan are revealing their vast potential to make everyday surfaces safer.
