Purple leaves give ornamental trees their seasonal appeal, but in some cultivars this striking color does not last. 

The Korea Research Institute of Standards and Science (KRISS, President Dr. Lee Ho Seong) has developed an ultra-sensitive immunoassay-based analytical platform that can detect and quantify trace amounts of “Small Excised Damaged DNA (sedDNA)” fragments generated during cellular DNA repair. This technology enables highly sensitive detection with quantification down to the level of several thousand molecules, measuring up to 22 times more DNA fragments than conventional methods. It provides a new analytical foundation for comparing DNA repair capacity between individuals and studying cellular responses to anticancer drugs and carcinogenic agents.

Seed-grown Cannabis sativa crops often vary in flowering time, yield, sex expression, and chemical profile, making large-scale production less predictable. 

Seoul National University College of Engineering announced that a research team led by Prof. Seung Hwan Ko of the Department of Mechanical Engineering has developed an artificial skin technology that enables robots to sense temperature and pressure simultaneously, similar to human skin.
