To monitor areas affected by wildfires or floods using satellites, it is necessary to be able to image those locations again when needed. With a single satellite, it takes time to revisit the same area, but operating multiple satellites together can increase observation opportunities. Five NEONSAT microsatellites, part of a constellation development project led by KAIST, are heading into space aboard the Nuri launch vehicle. KAIST (President Choongsik Bae) announced on October 6 that NEONSAT

When new information is continually added and old information is removed, an AI system may fail to find the correct material even when that material exists. KAIST researchers have developed a vector database technology that preserves the search paths leading to the needed information as data changes. This allows AI to find up-to-date information more accurately and quickly. KAIST (President Choongsik Bae) announced on October 5 that a research team led by Professor Min-Soo Kim from the School

Lymphatic vessels act as the body’s “drainage system,” collecting excess fluid from tissues. When lymphatic drainage is impaired because lymphatic vessels are underdeveloped, damaged, or dysfunctional, lymphedema can develop, causing swelling, particularly in the arms and legs. Conversely, excessive lymphatic vessel growth around tumors can facilitate cancer metastasis by providing routes for tumor cells to spread. Korean researchers have discovered that VEGF-C brings two VEG

Azobenzene is one of the best-known molecules that can be switched between two forms by light. However, the question of how the molecule moves in the first few picoseconds (trillionths of a second) after it absorbs light has remained unresolved for nearly 50 years. A Korean research team has now shown that, during the initial stage of the reaction, the molecule changes shape through a coordinated motion of the two nitrogen atoms at its center, while its two benzene rings stay nearly in place.

A Venus flytrap closes its leaves to trap prey when it senses a stimulus. Taking inspiration from this plant, KAIST researchers have combined the roles of a skin that senses approaching objects and a muscle that grasps them in a single soft material. When an electrically charged object comes near, ions inside the material move and produce an electrical signal. When ultraviolet (UV) light is applied, the material bends and grasps the object. Because it holds its deformed shape for more than 10
