Professor Suk Bong Hong (School of Environmental Science and Engineering) and his research group have discovered that PST-1 (POSTECH number 1), the newly named synthetic small-pore zeolite molecular structure, selectively adsorbs hydrogen.The zeolites’ ability to discriminate between molecules of different sizes and shapes has long been recognized. However, examples of selective adsorption of the smallest gases in zeolites are scarce.PST-1, the synthetic small-pore zeolite with the natrolite topology and a potassium gallosilicate composition, was discovered to adsorb only the smallest ga..
In the Steven Spielberg movie A.I., robots not only resemble humans in looks but read their facial expressions, reacting accordingly. With the new technology developed by Professor Daijin Kim (Department of Computer Science and Engineering) and his group, the movie may soon become reality.Automatic expression analysis is difficult because people’s faces vary so much. Existing software could effectively recognize only extreme expressions, which is not particularly helpful in real-life situations. But the system developed by Professor Kim’s team recognizes even slight facial movement..
Astudy revealed that thermosensory neurons of ectotherms affect lifespan at warm temperature by changing the activity of a steroid-signaling pathway that regulates longevity.Professor Seung-Jae Lee (Department of Life Science, School of Interdisciplinary Bioscience and Bioengineering, Division of IT Convergence Engineering) and his team, in collaboration with University of California, San Francisco, discovered that thermosensory neurons of C. elegans (Caenorhabditis elegans), an ectotherm, actively regulates the temperature dependence of lifespan.Many ectotherms, including C. elegans, have sho..

According to the Ministry of Education, Science and Technology, Thursday, POSTECH had 17 students give up their studies at the university last year, out of a total of 1,711 ― 1 percent of the total student body. The average dropout rate among institutes of higher education, including 2-year and 3-year colleges, stood at 5 percent. Among those who left their original schools, 44 percent voluntarily withdrew, 33 per..
Korean scientists have identified the structure of a protein linked to epilepsy and other brain function abnormalities, which they say could present new opportunities in treatment and drug development. In a study published by peer-review European Molecular Biology Organization (EMBO) Journal, a team of researchers led Kim Kyung-jin of Pohang University of Science and Technology (POSTECH) presented the crystal structure of the succinic semialdehyde dehydrogenase (SSADH) protein. SSADH deficiency has been associated with epilepsy and other neurological conditions, and understanding the structure..
Mad cow disease made headlines in the early 2000s when 4.4 million cattle in the United Kingdom alone were killed as a precaution against it. Now, there may be a way to not only trace the disease in its incubation period but also medically treat it. Professor Daehee Hwang (School of Interdisciplinary Bioscience and Bioengineering) and his group, in collaboration with the Institute for Systems Biology (ISB), the McLaughlin Research Institute, the University of California, San Francisco, the Allen Brain Institute, and the European Bioinformatics Institute, have spotted a set of genes that go hay..
As technology continues to get smaller, and as memory needs become more demanding, the microelectronics industry requires devices that are more cost-efficient and lightweight. And, while organic memory materials have shown some promise on improvement in performance and reductions in cost, they still lack some of the essential qualities, such as durable performance even in a harsh condition, needed for application in a wide variety of fields. So-called Non-Volatile Memories (NVM) from thermally and dimensionally stable polymer materials could provide a solution.The devices, developed by Profess..
Improvements in performance and reductions in cost of silicon-based nonvolatile memories, such as flash random access memory (flash-RAM), have rendered floppy discs and many other forms of portable storage obsolete. But for many uses that require data to be written only once, such as archiving and security applications, their cost effectiveness is limited. So-called write-onceread- many (WORM) memories made from low-cost polymer materials could provide a solution. The devices, developed by Professors Moonhor Ree, Ohyun Kim, Su-Moon Park and their research teams, are based on hyperbranched copp..
