Biomimetic Carbon Nanotube Fiber Synthesis Technology Developed
The byssus of the mussel allows it to live in harsh conditions where it is constantly battered by crashing waves by allowing the mussel to latch onto the seaside rocks. This particular characteristic of the mussel is due to the unique structure and high adhesiveness of the mussel’s byssus.
KAIST’s Professor Hong Soon Hyung (Department of Material Science and Engineering) and Professor Lee Hae Shin (Department of Chemistry) and the late Professor Park Tae Kwan (Department of Bio Engineering) were able to reproduce the mussel’s byssus using carbon nanotubes.
The carbon nanotube, since its discovery in 1991, was regarded as the next generation material due to its electrical, thermal, and mechanical properties. However due to its short length of several nanometers, its industrial use was limited.
The KAIST research team referred to the structure of the byssus of the mussel to solve this problem.
The byssus is composed of collagen fibers and Mefp-1 protein which are in a cross-linking structure. The Mefp-1 protein has catecholamine that allows it to bind strongly with the collagen fiber.
In the artificial structure, the carbon nanotube took on the role of the collagen fibers and the macromolecular adhesive took on the role of the catecholamine. The result was a fiber that was ultra-light and ultra-strong.
The results of the experiment were published in the Advanced Materials magazine and is patent registered both domestically and internationally.

Research Conducted on the Development Policy of Medical Researchers in United States
The topic dealt in the paper was “The Vietnam War and Medical Research: Untold Legacy of the U.S. Doctor Draft and the NIH ‘Yellow Berets’” and basically deals how a Doctor Draft made a positive impact on improving the basic research of clinical medicine.
Professor Park received his Doctorate at Johns Hopkins University and came to KAIST in 2007.
Summary of Dissertation
From the start of the Korean War in 1950 to the end of the Vietnam War in 1973 a large number of medical school graduates were drafted to the army. Of those drafted, 100 personnel were chosen annually to focus on researching in the National Institute of Health who developed into leaders of the field.
For example, those who worked as a researcher at the National Institute instead of their armed services were 1.5 times more likely to become a tenured professor, 2 times more likely to be promoted to Dean of the department, and 3 times more likely to be the Dean. In addition, 9 out of 50 Nobel Prize winners in fields of natural sciences between 1985 and 2007 were from the same pool of researchers, and 10 out of 76 recipients of National Medal of Science were also from the same pool of researchers.
They were named the ‘Yellow Berets’ like the special forces ‘Green Berets’ and made great contribution to the field in implementing and executing the bench to beside culture that involves development in laboratories to clinical testing.
Professor Park maintains that there has to be improvements made in current policies to encourage research work in medical graduate schools.

Sound of sex could alert internet porn filter by New Scientist, May 20, 2011
Software that can detect obscene contents from the internet has been developed by a research team at KAIST. The research team used a signal-processing technique, Randon Transform, to create spectrograms of a variety of audio clips, which can screen any pornographic sounds from websites. This audio-based screening method solves technological limits presented by automatic image-analysis systems that have already been used to catch unwanted pornography. New Scientist posted an online article on this development of new technology. Please copy and paste the following link to read more about the article.

'WWW2014' to be held in Seoul
WWW2014 (World Wide Web 2014) will be held in Seoul.
KAIST, Agency for Technology and Standards, W3C (World Wide Web Consortium), and ETRI (Electronics and Telecommunications Research Institute) all worked in cooperation to have WWW2014 in Seoul. The announcement that WWW2014 will be held in Seoul was announced in the Closing Ceremony of WWW2011 India Conference. Seoul overtook Adelaide and Melbourne of Australia.
Hosting WWW2014 in Seoul will be a great opportunity to showcase Korea’s Web Technology and get a grasp on the current trend in the field of high tech web technology and services.
The WWW conferences are attended by over 1,000 experts all over the world and are the world’s largest international conference in the field of IT.
Efforts to host the conference in their own respective countries are made on a national scale. The WWW2011 was hosted in India with the President of India giving an opening ceremony speech and WWW2013 will be hosted in Brazil in part due to the President himself sending a letter to express their desire to host WWW conference.

Artificial Photosynthesis Technology Developed using Solar Cell Material
Humanity is facing global warming and the exhaustion of fossil fuel. In order to remedy these problems, efforts to produce fuel without the production of carbon dioxide using solar energy continues constantly.
KAIST’s Professor Park Chan Beom and Professor Ryu Jeong Ki’s research teams of the department of Material Science and Engineering has developed an artificial photosynthesis system that mimics the photosynthesis in nature using solar cell technology.
The development of the technology is sure to pave the way to ‘Eco-Friendly Green Biological Process’.
Photosynthesis is the process by which a biological entity produces chemical products like carbohydrates using physical and chemical reactions using solar energy as its energy source.
Professor Park’s team was able to develop the artificial photosynthesis technology with a biological catalyst as its basis.
The result of the experiment was published in ‘Advanced Materials’ magazine on the 26th of April edition and has been patented.
