Engineered E. coli convert kimchi radish waste into biodegradable bioplastic
Every year, thousands of tons of radish by-products generated during kimchi production are discarded despite containing valuable carbon and nutrient resources. Researchers at the World Institute of Kimchi (WiKim) have developed a genome-scale model-guided microbial engineering strategy that enables these agricultural by-products to be…
Observations since 1850 reveal regional climate fingerprints of human-induced warming
There is no question that the current global temperature increase is human-caused. Global warming has long since emerged as the dominant signal amid natural climate fluctuations. However, identifying how this warming manifests regionally remains a key challenge.
