A Molecular Switch Controlling Self-Assembly of Protein Nanotubes Discovered
International collaborative research among South Korea, United States, and Israel research institutionsThe key to the treatment of cancer and brain disease mechanism The molecular switch that controls the self-assembly structure of the protein nanotubes, which plays crucial role in cell division and intracellular transport of materials, has been discovered. KAIST Bio and Brain Engineering Department’s Professor Myeong-Cheol Choi and Professor Chae-Yeon Song conducted the research, in collaboration with the University of California in Santa Barbara, U.S., and Hebrew University in Israel. The findings of the research were published in Nature Materials on the 19th. Microtubules are tube shaped and composed of protein that plays a key role in cell division, cytoskeleton, and intercellular material transport and is only 25nm in diameter (1/100,000 thickness of a human hair). Conventionally, cancer treatment focused on disrupting the formation of microtubules to suppress the division of cancer cells. In addition Alzheimer’s is known to be caused by the diminishing of structural integrity of microtubules responsible for intercellular material transport which leads to failure in signal transfer. The research team utilized synchrotron x-ray scattering and transmission electron microscope to analyze the self assemble structure of protein nanotubes to subnanometer accuracy. As a result, the microtubules were found to assemble into 25nm thickness tubules by stacking protein blocks 4 x 5 x 8nm in dimension. In the process, the research team discovered the molecular switch that controls the shape of these protein blocks. In addition the research team was successful in creating a new protein tube structure. Professor Choi commented that they were successful in introducing a new paradigm that suggests the possibility of controlling the complex biological functions of human’s biological system with the simple use of physical principles. He commented further that it is anticipated that the findings will allow for the application of bio nanotubes in engineering and that this is a small step in finding the mechanism behind cancer treatment and neural diseases.

Is it possible to identify rumors on SNS?
Rumors
sporadically spread with people with fewer followers in the centerResearched
over 100 rumors in the US from 2006 to 2009 Is it
possible to filter information on SNS such as Twitter and Facebook? A research
team led by Professor Mee-Young Cha from the Department of Cultural Technology
Graduate School at KAIST, Professor Kyo-Min Jung of Seoul National University,
Doctor Wei Chen and Yajun Wang of Microsoft Asia, has developed a technology
that can accurately filter out information on Twitter to 90% accuracy. The
research not only deduced a new mathematical model, network structure, and
linguistic characteristics on rumors from SNS data, but is also expected to
enhance the effort to make secure technology to regulate Internet rumors. The team
analysed the characteristics of rumors in over 100 widespread cases in the US
from 2006 to 2009 on Twitter. The team gathered data, which included a range of
areas such as politics, IT, health and celebrity gossips, and their analysis
could identify rumors to 90% accuracy. The filtering was more accurate in
rumors that included slanders or insults. The
research team identified three characteristics of the spread of rumors. Firstly,
rumors spread continuously. Normal news spreads widely once and is mentioned
rarely again on media, but rumors tend to continue for years. Secondly,
rumors spread through sporadic participation of random users with no
connections. Rumors start from people with fewer followers and spread to the
more popular. This phenomenon is often observed in rumors concerning
celebrities or politicians. Lastly,
rumors have unique linguistic characteristics. Rumors frequently include words
(such as “it may be true,” “although not certain, I think,” “although I cannot
fully remember”) related to psychological processes that question, deny, or
infer the reliability of the information. Professor
Cha said, “This research deduced not only a statistical and mathematical model
but also is an integrated research on social psychological theory on the
characteristics of rumors that attract great attention from the society based
on ample data.” The results
were made public in IEEE International Conference on Data Mining last December
in Texas, USA.

Professor Suk-Bok Chang receives 14th Korea Science Award in the field of Chemistry
Professor Suk-Bok Chang from the Department of Chemistry at KAIST received the “2013 Korea Science Award” in chemistry hosted by the National Research Foundation and the Ministry of Science, ICT, and Future Planning, Republic of Korea.
The Korea Science Award is a presidential award of Korea, which was first established in 1987 to recognize research excellence in natural science. Three scientists are selected for the award in every other year.
Professor Chang primarily researches the catalyzing mechanism of carbon-hydrogen bonds in organic molecules. He has succeeded in making great progress in the field of organic chemistry especially in developing a new type of transition metal catalytic behavior that can be applied to low-reactivity compounds.
Hydrocarbons are abundant in nature, but its unreactive nature in ambient conditions makes it unsuitable as reactant for compound synthesis. In addition, the mechanism behind transition metal catalyzed carbon-hydrogen bond synthesis has not been proven sufficiently.
The prediction that fossil fuels will be depleted before the end of the century makes hydrocarbon synthesis an extremely important matter.
The need for an effective hydrocarbon synthesis method inspired Professor Chang to pursue research in the transition metal catalysis method and to develop a catalytic system that would allow efficient synthesis even in ambient conditions.
Professor Chang has been the lead researcher for the Institute for Basic Science’s “molecule catalysis reaction research team” since December 2012 and has been carrying out this research in KAIST.

Through the sessions of the Global University Leaders Forum, IdeasLab, and Global Agenda Councils on Biotechnology, KAIST participants will actively engage with global leaders in the discussion of issues on education innovation and technological breakthroughs.
The 2014 Annual Meeting of the World Economic Forum (WEF), known as the Davos Forum, will kick off on January 22-25 in Davos-Klosters, Switzerland, under the theme of "The Reshaping of the World: Consequences for Society, Politics, and Business." Each year, the Forum attracts about 2,500 distinguished leaders from all around the world and provides an open platform to identify the current and emerging challenges facing the global community and to develop ideas and actions necessary to respond to such challenges.
President Sung-Mo Steve Kang and Distinguished Professor Sang Yup Lee from the Department of Chemical and Biomolecular Engineering, KAIST, will attend the Forum and engage in a series of dialogues on such issues as Massive Open Online Courses, new paradigms for universities and researchers, the transformation of higher education, the role and value of scientific discoveries, and the impact of biotechnology on the future of society and business.
At the session entitled "New Paradigms for Universities of the Future" hosted by the Global University Leaders Forum (GULF), President Kang will introduce KAIST"s ongoing online education program, Education 3.0. GULF was created in 2006 by WEF, which is a small community of the presidents and senior representatives of the top universities in the world.
Implemented in 2012, Education 3.0 incorporates advanced information and communications technology (ICT) to offer students and teachers a learner-based, team-oriented learning and teaching environment. Under Education 3.0, students study online and meet in groups with a professor for in-depth discussions, collaboration, and problem-solving. KAIST plans to expand the program to embrace the global community in earnest by establishing Education 3.0 Global in order to have interactive real-time classes for students and researchers across regions and cultures.
President Kang will also present a paper entitled "Toward Socially Responsible Technology: KAIST"s Approach to Integrating Social and Behavioral Perspectives into Technology Development" at another session of GULF called "Seeking New Approaches to Critical Global Challenges." In the paper, President Kang points out that notwithstanding the many benefits we enjoy from the increasingly interconnected world, digital media may pose a threat to become a new outlet for social problems, for example, Internet or digital addiction.
Experts say that early exposure to digital devices harms the healthy development of cognitive functions, emotions, and social behavior. President Kang will introduce KAIST"s recent endeavor to develop a non-intrusive technology to help prevent digital addiction, which will ultimately be embedded in the form of a virtual coach or mentor that helps and guides people under risk to make constructive use of digital devices. President Kang stresses the fundamental shift in the science and technology development paradigm from research and development (R&D) to a research and solution development (R&SD), taking serious consideration of societal needs, quality of life, and social impacts when conducting research.
Professor Sang Yup Lee will moderate the IdeasLab session at the Davos Forum entitled "From Lab to Life with the California Institute of Technology (Caltech)." Together with scientists from Caltech, he will discuss scientific breakthroughs that transform institutions, industries, and individuals in the near future, such as the development of damage-tolerant lightweight materials with nanotechnology, the ability to read and write genomes, and wireless lab-in-the-body monitors. In addition, he will meet global business leaders at the session of "Sustainability, Innovation, and Growth" and speak about how emerging technologies, biotechnology in particular, will transform future societies, business, and industries.
As a current special adviser of the World Economic Forum"s (WEF) Chemicals Industry Community, Professor Lee will meet global chairs and chief executive officers of chemical companies and discuss ways to advance the industry to become more bio-based and environmentally friendly.

Mechanism in regulation of cancer-related key enzyme, ATM, for DNA damage and repair revealed
Professor Kwang-Wook Choi
A research team led by Professor Kwang-Wook Choi and Dr. Seong-Tae Hong from the Department of Biological Sciences at KAIST has successfully investigated the operational mechanism of the protein Ataxia Telangiectasia Mutated (ATM), an essential protein to the function of a crucial key enzyme that repairs the damaged DNA which stores biometric information. The results were published on December 19th Nature Communications online edition.
All organisms, including humans, constantly strive to protect the information within their DNA from damages posed by a number of factors, such as carbonized materials in our daily food intake, radioactive materials such as radon emitting from the cement of buildings or ultraviolet of the sunlight, which could be a trigger for cancer.
In order to keep the DNA information safe, the organisms are always carrying out complex and sophisticated DNA repair work, which involves the crucial DNA damage repair protein ATM. Consequently, a faulty ATM leads to higher risks of cancer.
Until now, academia predicted that the Translationally Controlled Tumor Protein (TCTP) will play an important role in regulating the function of ATM. However, since most of main research regarding TCTP has only been conducted in cultured cells, it was unable to identify exactly what mechanisms TCTP employs to control ATM.
The KAIST research team identified that TCTP can combine with ATM or increase the enzymatic activity of ATM. In addition, Drosophilia, one of the most widely used model organisms for molecular genetics, has been used to identify that TCTP and ATM play a very important role in repairing the DNA damaged by radiation. This information has allowed the researchers to establish TCTP’s essential function in maintaining the DNA information in cell cultures and even in higher organisms, and to provide specific and important clues to the regulation of ATM by TCTP.
Professor Kwang-Wook Choi said, “Our research is a good example that basic research using Drosophilia can make important contributions to understanding the process of diseases, such as cancer, and to developing adequate treatment.”
The research has been funded by the Ministry of Science, ICT and Future Planning, Republic of Korea, and the National Research Foundation of Korea.
Figure 1. When the amount of TCTP protein is reduced, cells of the Drosophila's eye are abnormally deformed by radiation. Scale bars = 200mm
Figure 2. When the amount of TCTP protein is reduced, the chromosomes of Drosophilia are easily broken by radiation. Scale bars = 10 mm.
Figure 3. When gene expressions of TCTP and ATM are reduced, large defects occur in the normal development of the eye. (Left: normal Drosophilia's eye, right: development-deficient eye)
Figure 4. ATM marks the position of the broken DNA, with TCTP helping to facilitate this reaction. DNA (blue line) within the cell nucleus is coiled around the histone protein (green cylinder). When DNA is broken, ATM protein attaches a phosphate group (P). Multiple DNA repair protein recognizes the phosphate as a signal that requires repair and gathers at the site.
