Visualizing microglia in brain tissue with a fluorescence turn-on substrate
Part of the immune system in the brain is made up of so-called microglia cells. Korean and Singaporean researchers have now developed a fluorescent probe that specifically labels this type of macrophage. The cells were visualized in cell culture and in the live brains of rodents. As detailed in ...
A fluorescent molecule for screening Gram-positive bacteria
Two years ago, a group of infants died at the university hospital and it was found to be Gram-negative bacteria that caused their death. The Gram-negative bacteria turn into pink color and Gram-positive bacteria turn into violet color when stained using the Gram stain which is a bacterial ...
Prof. Wan Kyun Chung with PhD student Young Jin Heo, MS student Junsu Kang, and postdoctoral researcher Min Jun Kim in the Robotics Laboratory at POSTECH, Korea, have developed a novel control algorithm to resolve critical problems induced from a Proportional-Integral-Derivative (PID) controller ...
Prof. Hyung Joon Cha (Dept. of Chemical Engineering) and a team of researchers examined the behavior of sea anemone to create a mechanically durable hydrogel. Since the body length and width of sea anemone varies almost ten-fold by shrinking rapidly and expanding slowly under stimulus, the team ...
Fluorescence lights up cells programmed to die
Programmed cell death, or apoptosis, occurs tens of millions of times every day in every human body. Researchers in South Korea have devised an easy method to detect apoptotic cells by fluorescence, as they report in Chemistry—An Asian Journal. Their method makes it easier to detect improper ...
Focus on maximizing yields in crops such as rice and corn
BASF Plant Science, Genomine, the South Korean venture company and POSTECH, the South Korean university, entered a license agreement. Focus is on the discovery of genes that help maximize yields in staple food and feed crops such as rice and corn. This includes genes that increase yield under ...
