The rapid development of vaccines and treatments has become more important than ever to combat numerous viruses, including COVID-19. On average, it takes 10 to 15 years, and an astronomical cost of more than 1 trillion KRW, to develop a new vaccines. This is because it is difficult to fully reproduce the environment in the body with existing platforms, which mainly use 2D cell culture or animal testing. To increase the success rate, a precise description of the environment in the body is the key. Professor Sung June Jung (MSE) and Dr. Yun-ji Kim’s research team succeeded in creating an artific

On July 1, a car crash at the intersection of Seoul City Hall Station left many people injured or dead. The perpetrator of the accident claimed that sudden unintended acceleration due to vehicle defects caused the accident, saying, “The more I stepped on the brake, the faster the car went.” Sudden unintended acceleration is a phenomenon in which a car is accelerated out of the driver’s control. However, in a briefing on the results of a comprehensive investigation by Namdaemun Police Station in Seoul on Aug. 1, officers concluded that the driver’s careless driving caused the accident. Although

Last August, Korea’s stock markets, as well as those in the United States and Japan, plunged. The phenomenon is called “Black Monday,” in just one day, the stock market shows a sharp decline beyond the market’s control. In Korea, 2,335 trillion KRW in market capitalization evaporated through the KOSPI and KOSDAQ. As the deterioration became too severe, a circuit breaker was triggered to stop trading temporarily. This led to several investors facing a new situation, with some panicking and making momentary choices, while others peeked at new opportunities. On Wall Street in New York in 1987, Bl

On April 16, local time, the United Kingdom passed a tobacco and e-cigarette bill to create a smoke-free generation by a vote of 383 in favor and 67 against. According to the bill proposed by the government to create a “smoke-free generation,” the legal age to purchase tobacco will be increased by one year annually, meaning that individuals born on or after Jan. 1, 2009 (currently 15 years old) will never be able to buy tobacco in the UK legally. This measure effectively prohibits the sale of tobacco to anyone below a certain age. The bill also includes provisions that ban disposable e-cigaret

These days, most university students are relying on electronic devices like mobile phones, tablet PCs, and laptops, during lectures. Rather than buying paper textbooks, they simply load textbook files onto their devices. Only a few students are accessing these textbook files through legitimate means. Furthermore, some students purchase or sell these files through illegal channels. In extreme cases, it has been reported that some students even share previous exam questions without any permission from the professor. All of these are acts of copyright infringement, but most students are either un
