Discovery opens door to new strategy for protecting humans against infection. A recent study revealed that cinereous vultures, also known as Aegypius monachus, have a unique genetic make-up which enable them to thrive on carcasses without being affected by the harmful bacteria living on these remains. The study was jointly conducted by Dr. Jong Hwa Bhak (School of Life Science) of UNIST and Dr. Woon Kee Paek of National Science Museum of Korea. According to Dr. Bhak, a geneticist and lead Read more

Paving the Way for Cost-effective Production of Xylitol

이성국 교수(좌)와 유영신 연구원(우)이 제1공학관 6층 실험실에서 활짝 웃고 있다. 이들은 섬유소가 많은 볏짚이나 옥수수 줄기 등도 잘 발효시킬 수 있는 '슈퍼 미생물' 제작법을 개발했다.
Engineering, super-microbes that is capable of producing xylitol from non-food resources. Due to the current environmental problems, such as depletion of natural resources, much attention has been paid to the use of biomass as an alternative energy source. However, because biomass is biological material derived from living organisms, the conversion of biomass into energy production can be very costly. New research findings announced today offers a more effective, economic, and sustainable Read more

A Molecular View of Sperm Navigation

STORM_0006_xyz1_noscale
Among 10 million sperm racing for one egg, only a few sperm cells succeed to arrive at the right place and time for fertilization. What is the mechanism behind this extreme selection of one out of million? Sang-Hee Shim unveiled a molecular weapon of winning sperms in an article published in CELL. Shim and her colleagues at Harvard University and Harvard Medical School resolved three-dimensional (3D) structure of calcium signaling domains on the whole sperm tail. Resolving structures in sperm Read more

New insights into ribosome assembly

From Hajin Nature2014 RNA-protein interaction
The ribosome is the cellular machinery to synthesize proteins. The ribosome itself is a complicated assembly of more than 50 proteins and several long strands of RNA. A recent study by Dr. Hajin Kim, reported in the journal Nature, offers new clues about how the ribosome, the master assembler of all proteins, also assembles itself. “The ribosome has more than 50 different parts and many of them even look similar to others. It is pretty amazing if you imagine how they assemble correctly,” said Read more

Microfluidics: Researchers developed a lab-on-a-disc that detects Salmonella in milk in about 30 minutes By Erika Gebel Berg (Chemical & Engineering News) To speed up and simplify the identification of foods tainted with Salmonella bacteria, researchers have built a microfluidic disc that can detect the pathogens’ DNA in product samples. As the device spins, it performs DNA extraction, amplification, and detection in less than 30 minutes (Anal. Chem. 2014, DOI: 10.1021/ac403971h). Salmonella Read more

Caffeine “Traffic Light”: Do you want to know how much caffeine is in your drink?

A team of researchers led by Prof. Young-Tae Chang from National University of Singapore and Prof. Yoon-Kyoung Cho from Ulsan National Institute of Science and Technology (UNIST), Korea, developed a fluorescent caffeine detector and a detection kit that lights up like a traffic light when caffeine is present in various drinks and solutions. The research work was published in Scientific Reports (Nature Publishing Group) on July 23, 2013. Caffeine drinks are ubiquitous and it would be unimaginable Read more
