If you are suffering from cancer and need interferon therapy, or if you need human growth hormone for the treatment of short stature, you could not escape unpleasant repetitive injections. The former requires thrice-a-week injections and the latter needs daily injections. However, such frequent injections are no longer necessary, thanks to a new drug delivery device developed by a POSTECH research team.For long-term controlled delivery, protein drugs had been encapsulated within biodegradable polymers such as poly (lactic-co-glycolic acid), PLGA. Despite successful commercialization, however, ..
The Core Technology for Ultrafast Silicon Device THE core technology that enables the realization of the fastest, nearly massless electrons has been successfully devised by a research team led by Professor Han Woong Yeom, Director of the Center for Atomic Wires and Layers at POSTECH. This achievement may lead to a breakthrough in the development of a truly new technology for semi-conductor devices. Professor Yeom’s team successfully developed a core technology that will enhance the speed of a silicon device by several ten-folds through utilizing the interface, which is the boundary betwe..
Anisotropic Fatigue Behavior of Magnesium Alloys InvestigatedENVIRONMENTAL protection has surfaced as a major problem that the world needs to solve, and there is no doubt that car pollution takes up a large portion of it. Therefore, the need for eco-friendly cars or ‘Green cars’ with lower emissions and more fuel efficiency is has increased, which explains why the recent work on the related subject conducted by POSTECH and the Korea Research Institute of Standards Science (KRISS) is gaining significance. It has been reported that Professor Chong Soo Lee and Sung Hyuk Park, a Ph.D. ..
A Newly Discovered Mechanism May Lead to Climate RegulationAteam of environmentalphotochemists led by Professor Wonyong Choi of POSTECH has succeeded in explaining how natural ice in Polar Regions can provide the ocean with bioavailable iron content, which ultimately contributes to the prevention of global warming. This achievement in research has gained substantial attention from the international community as it was introduced in several well-known publications in the field of science and technology such as the May 6th issue of Environmental Science & Technology, and the May 17th issue o..

Postech and Max Planck scientists have already been cooperating in both fields and will intensify the exchange of know-how and staff, jointly training junior scientists within the framework of the Centers, which are intended to put the visibility of cooperations on selected ground-breaking research topics with high-performing international partners onto a broad footing.Partners from Australia, China and Japan are also represent..
* Link : http://www.koreatimes.co.kr/www/news/special/2010/06/181_68158.htmlBy Baik Sung-giPOSTECH presidentThe 20th century was a time of tremendous changes and progresses, largely due to the technological breakthroughs in fields such as microelectronics, telecommunication, biotechnology, nanotechnology, manufacturing processes, logistics, etc. New businesses have been created and productivity has been increased dramatically, producing wealth and values contributing to the economic, social, and in some cases, even political development, spreading from the U.S., Europe, and Japan, to Asia and ..
Professor Hyung Joon Cha (Department of Chemical Engineering) and his team have succeeded in developing a highly condensed liquid bio-adhesive material based on the mussel adhesive proteins (MAPs) by complex coacervation, which shows superior adhesive properties. Recently, MAPs found in byssus of mussel, have come to be recognized as useful biomaterials for direct use as bio-adhesives in medical applications and in the engineering of new marine-inspired adhesive materials. As purified natural MAPs are difficult to obtain, it has not been possible to experimentally validate the complex coacerva..
Professor Jaesung Park (Department of Mechanical Engineering) and Korea- America co-research team including medical school of Harvard University have succeeded in observing the mutual interaction between the layers of primary hepatocyte (liver) cells and non-parenchymal (functional) cells created by the stencil created by the microfabrication techniques.To treat damaged or diseased liver tissue, hepatic tissue engineering has been studied as a new therapeutic approach. The reconstruction of functional hepatic tissue mainly depends on the ability to control factors that influence the cell envir..
Professor Youngsook Lee (Division of Integrative Biology and Biotechnology) and her team have found a transporter carrying abscisic acid (ABA), a stress hormone, synthesized in plants undergoing stresses like extreme climate or salinity. Their results integrate ABA dependent signaling and transport processes, and it is expected to open a new venture for the engineering of drought-tolerant plants.They have succeeded to find the existence of transporter ABCG40 that can transport ABA, a hormone known to be produced in responses to environmental stress such as extreme temperatures, high salinity, ..
President Baik’s interviews were featured on the major Vietnamese newspapers on May 20 and 21.
