Despite its potential risks, general anesthesia and how it leads human brain to unconsciousness is still not known. A POSTECH research group has been investigating the nature of consciousness as well as control of the level of consciousness through anesthesia, whose effort has drawn much attention of the academia.Professor Seunghwan Kim (Department of Physics) and his team, in a joint study with POSTECH graduate Doctor UnCheol Lee of University of Michigan and a Seoul Asan Medical Center team, have presented evidence that the transition from consciousness to unconsciousness occurs by the suppr..
Many studies have addressed the effect of sugar in the diet on obesity and diabetes. Professor Seung-Jae Lee (Division of IT Convergence Engineering, Department of Life Science, School of Interdisciplinary Bioscience and Bioengineering) and his group report that it might also be taking years off the life span.Professor Lee’s group, in collaboration with Professor Cynthia Kenyon of the University of California, San Francisco, discovered that glucose inhibits the activities of the glycerol channel in C. elegans, shortening the life span of the worm by about 20 percent. The group traces the..
Professor Jin Kon Kim (Department of Chemical Engineering) and his group have succeeded in developing macromolecule materials which use pressure to store terabit-scale ultrahigh-density data at room temperature, as well as the supporting technology to write, read, and erase the ultrahighdensity array of nanoscopic indentations.The existing technology for fabricating nanopatterns, developed by IBM, was based on a thermomechanical recording system, using a heated atomic force microscope (AFM) tip at about 350°C. However, in addition to the difficulties in the fabrication of heated AFM tips, ..
Professor Kijung Yong (Department of Chemical Engineering) and his group have succeeded in developing an original technology utilizing the lotus effect, which may be used toward development of a variety of applications using coated surfaces.Leaves of the lotus flower have very high water repellency due to the complex, nanoscopic structure of their surface. Superhydrophobic nanostructured surfaces, such as the lotus leaf, have shown potential for a variety of applications, including microfluidics in biotechnology, fog-resistant coatings, impermeable textiles, anti-contamination, and self-cleani..

Some universities require that even the departments of Korean literature and Korean history offer courses taught in English. Some professors are in favor of these "globalizing" changes, while others are doubtful.Amid the controversy, Pohang University of Science and Technology or POSTECH recently announced that it will transform into an English-only zone withi..

It is the second initiative to be announced by President Baik Sung-gi in recent days. However, the school's plan ..

Professor Kyo Han Ahn (Department of Chemistry) and his team, in a joint research with a Yonsei University group, have developed a new probe for mercury that can be used for imaging organs in living organisms.Mercury is a highly toxic and widespread pollutant, but the existing fluorescence probes for it mostly detected only its inorganic forms. The element is commonly found in organic forms which are much more toxic than inorganic mercury as their lipophilicity allows them to cross biological membranes. Consequently, new ways of detecting organic mercury species, particularly in organisms, was..
Professor Moonhor Ree (Department of Chemistry) and his research group, in a joint research with a Dongguk University Medical School team (Professor Heesoo Kim), successfully synthesized new brush polymers. The newly developed brush polymers are suitable for use in biomedical applications including medical devices and biosensors that require biocompatibility and the reduced possibility of post-operative infection.Because cell membranes play an important role protecting the material inside the cell and maintaining the structure and function of the cell, studies on polymer materials that mimic m..
Professor Taihyun Chang (Department of Chemistry) and his group have developed toroidal micelles of uniform size from diblock copolymers.Block copoloymers can spontaneously self-assemble in a selective solvent to form micelles of various morphologies such as spherical micelles, cylindrical micelles, and vesicles. Recently, the variety of micellar shapes have been expanded to unconventional forms including toroids, tubes, disks, helices, and other complex forms.Although the toroid-shaped micelles have been reported earlier, the applicability of the toroid structure had been low due to the diffi..
