The research team of Professors Jaesung Park (Department of Mechanical Engineering) and Yong Song Gho (Department of Life Sciences) has developed a way to generate artificial nanovesicles that can be used to deliver RNA, a breakthrough that is expected to be used in exosomes research and to have applications in drug and RNA-delivery systems. Their paper, "Microfluidicfabrication of cell-derived nanovesicles as endogenous RNA carriers”,made it onto the cover of the journalLab on a Chipand was selected as a Hot Article. Exosomes/microvesicles are known to shuttle biological signals..

Professor Doghoon Hyeon (Department of Mathematics) will receive the best paper award given by the Korean Mathematical Society (KMS) with Professor Sung Yeon Kim (Kangwon National University).KMS announced that they will have a Spring 2014 meeting for reading research papers fromApril24 to 26 at Gangneung-Wonju National University where Professor Hyeon will receive his award for best paper.Professor Hyeon published his paper inAnnals of Mathematics, a journal published by Princeton University, in 2013. His paper titled, “Log minimal model program for the moduli space curves: The first fl..

The fundamental concepts of physics are crucial to understanding the correlation of the structure and strength of materials. Some materials, like a steel coil spring or rubber, are elastic. Grasping a rubber ball deforms the shape momentarily before it returns to its original state. Other materials when manipulated with, such as clay, will retain its newly deformed shape. This phenomenon, called plasticity, has been studied by scientists in designing high strength steels and alloys. The demand for high-technology metallic materials continues to depend on further research and understanding of ..

Professor Sung H. Han (Department of Industrial and Management Engineering) is an authority in the field of ergonomics, an applied science that deals with the design of devices and systems in conjunction with the physical working conditions, capacities, and requirements of the user. Professor Han has conducted research on human-computer interaction,effectiveproduct design, and the evaluation of product and service experience to provide better value to users. He has played a vital role in the establishment of Asia’s first National Institute of Ergonomics and is the founder of ACED (Asian ..

Professor Dong-Woo Cho’s team at POSTECH is engaged in the development of novel tissue and organ printing technology that can bridge that gap that currently exists between the supply and demand of tissues and organs for patients suffering from tissue loss or organ failure. This novel tissue printing technology could lead to the regeneration of healthy functional tissues or organs for patients, thus, eliminating the need for tissue grafts and mechanical devices. The POSETCH team made up of Falguni Pati, Jinah Jang, and Dong-Heon Ha, recently published their findings in an article entitle..

A research team, led by Department of Materials Science and Engineering Associate Professor Sei Kwang Hahn and graduate student Hwiwon Lee, has published research on a new rheumatoid arthritis treatment. The article “Hyaluronate – Gold Nanoparticle/Tocilizumab Complex for the Treatment of Rheumatoid Arthritis” was published in the April 2014 edition of the ACS Nano, a monthly scientific journal published by the American Chemical Society. Rheumatoid arthritis (RA) is a chronic inflammatory immune disease that affects 0.5 to 1 percent of the adult population worldwide and ..

Using POSTECH Professor Chulhong Kim’s custom-built high-resolution photoacoustic imager, researchers were able to examine the combination of nanonaps and photoacoustic tomography illuminated inside the intestine of a mouse. (Credit: Chulhong Kim) Millions of people worldwide who suffer from digestive diseases may soon have a safer alternative to traditional radiological techniques when visiting the hospital for imaging of the gastrointestinal tract. Researchers from the Pohang University of Science and Technology (POSTECH), the University at Buffalo, and University of Wisconsin&ndas..

POSTECH researchers have found another reason to cut down on a high-fat and cholesterol diet. Their findings show that cholesterol is crucial for Wnt signaling pathway often linked to human birth defects, cancer, and other diseases. Research groups of Prof. Jin-Kwan Han in the Department of Life Sciences at POSTECH and Prof. Wonhwa Cho from the University of Illinois at Chicago performed this study. Their research was published in the July edition of Nature Communications. Wnt signaling processes biological functions through ‘canonical’ and ‘non-canonical’ pathways..

Professor Yoon-Seok Chang (School of Environmental Science and Engineering), a worldwide authority on dioxin, has been selected as a first prize winner of the academic research award by the Korean Society of Environmental Engineers. An awards ceremony was held at the Kimdaejung Convention Center on August 21st. Over the past 30 years, Professor Chang has published nearly 200 SCI papers and studies which include analyses of toxic substances such as dioxins and other endocrine on human health. His study of the environmental risks of bio-nanomaterials has recently received academic attention.

Noise plays a key role in important biological processes, such as bacterial antibiotics resistance, cancer development, and stem cell differentiation. Physics can explain much of this biological phenomenon. Professor Nam Ki Lee of the Department of Physics and the School of Interdisciplinary Bioscience and Bioengineering with Department of Physics graduate students Sora Yang, Seunghyeon Kim, Cheolhee Kim, Hyeong Jeon An and Professor Jaeyoung Sung of Chung-Ang University studied how cells propagate noise using RNA polymerase. Their research was published in this month’s Nature Communica..
