Hospital surfaces are known hotspots for dangerous bacteria, contributing to the spread of healthcare-associated infections. But a new innovation from scientists at the University of Nottingham and University of Birmingham could help stop infections before they start: a germ-killing paint.

Researchers developed an antimicrobial coating by blending chlorhexidine digluconate (CHX)—a widely used antiseptic found in mouthwashes and skin cleansers—into commercially available epoxy resin. This simple yet effective formula turns everyday surfaces into powerful barriers against harmful microbes like MRSA, E. coli, Candida, and more.

The chances of two people sharing identical fingerprints are incredibly slim—about 1 in 640 billion. Even identical twins, who share the same DNA, have unique fingerprint patterns. Now, scientists have taken this uniqueness a step further with the development of a revolutionary electronic skin that features artificial fingerprints with a probability of duplication 10²³² times lower than human fingerprints.

A research team led by Professor Kyoseung Sim from the Department of Chemistry at UNIST (Ulsan National Institute of Science and Technology) has unveiled this cutting-edge electronic skin technology in a recent Nature Communicationspublication. The breakthrough could lay the groundwork for future AI-powered robots to possess uniquely identifiable fingertips—offering capabilities previously exclusive to biological organisms.

Researchers at Pohang University of Science and Technology (POSTECH) have developed a high-entropy alloy (HEA) that maintains both strength and flexibility across an exceptionally wide temperature range—from -196 °C to 600 °C. This breakthrough opens new possibilities for use in aerospace, automotive, and energy industries where materials are exposed to extreme or fluctuating temperatures.

The research team, led by Professor Hyoung Seop Kim from the Department of Materials Science and Engineering, the Graduate Institute of Ferrous Technology, and the Department of Mechanical Engineering at POSTECH, published their findings in the international journal Materials Research Letters.

A team of researchers has developed a pioneering methodology to replace diesel engines on ferry boats with pneumatic propellers, offering a cleaner, quieter, and potentially more cost-effective alternative for maritime transport.

The study, published in Energy Conversion and Management, outlines a system in which two air motors, each generating 250 kW, successfully powered a ferry along a fixed route in Finland’s maritime transport system. The experimental system demonstrated that pneumatic propulsion could meet the same performance standards as traditional diesel engines, but with significantly reduced environmental impact.
