Organic light-emitting diodes (OLEDs) are widely used in smartphones and TVs thanks to their excellent color reproduction and thin, flexible planar structure. However, internal light loss has limited further improvements in brightness. KAIST researchers have now developed a technology that more than doubles OLED light-emission efficiency while maintaining the flat structure that is a key advantage of OLED displays.

Although valued for their medicinal properties, ecological importance, and cultural heritage, mangrove habitats across the Arabian Gulf’s littoral states are under mounting threats. Despite their resilience and tolerance of scorching heat and hypersalinity, these ecosystems remain highly vulnerable to unchecked development and pollution. To safeguard these critical coastal forests, a new study calls for urgent, coordinated action rooted in the local context, guided by science, and supported by policy.

Air-polluting microplastics have been found in rural environments in greater quantities than in urban locations, researchers say. 

Scientists led by the University of Leeds detected up to 500 microscopic particles of plastic per square metre per day in an area of woodland during the three-month study – almost twice as much as in a sample collected in a city center. 

They believe trees and other vegetation capture airborne microplastic particles from the atmosphere and deposit them, highlighting the impact that different landscape and weather conditions have on the spread of the particles. 

And they say that these unexpected results challenge the assumption that microplastic pollution is mainly an urban problem. 

Researchers have developed formamidinium (FA)-alloyed cesium lead iodide perovskite nanoplatelets that combine improvements in phase stability with linearly polarized red emission. By precisely controlling A-site composition and surface ligand interactions, the team achieved uniform, well-oriented superlattices that maintain optical performance under ambient conditions. This breakthrough provides a new route toward stable, directionally controlled light sources for advanced photonic and display technologies.

“We know the genes, but not their functions.” To resolve this long-standing bottleneck in microbial research, a joint research team has proposed a cutting-edge research strategy that leverages Artificial Intelligence (AI) to drastically accelerate the discovery of microbial gene functions.

KAIST announced on Jan. 12 that a research team led by Distinguished Professor Sang Yup Lee from the Department of Chemical and Biomolecular Engineering, in collaboration with Professor Bernhard Palsson from the Department of Bioengineering at UCSD, has published a comprehensive review paper. The study systematically analyzes and organizes the latest AI-based research approaches aimed at revolutionizing the speed of gene function discovery.
