A high school in Hiroshima City has been the first to do something with DNA in the world. Its students have won praise not only for doing this research but also for presenting their findings to groups of expert scientists. The school is one of the Super Science High Schools allowed by the Ministry of Education, Culture, Sports, Science, and Technology, where students are given an opportunity to study science at an advanced level. Here, students use the same type of hitech experimental laboratories as those found at universities. In these labs, they conduct experiments and research in new fields of study not found in textbooks. As part of this science course, the students, with the help of Hiroshima University, used a machine called sequencer (音序器), and over the course of a year and a half they succeeded in decoding (解译) the DNA. They then presented their results to academic groups. Achieving a world first might sound very wonderful, but the process of decoding the DNA involved very hard work. The students were also responsible for maintaining the equipment, and they had to read difficult research papers and put in extra study beyond their regular schoolwork.

    "Researchers need to work hard. The work was tiring, but the students worked toward their ambitious goal of achieving a world first. They have a great sense of achievement, and the number of students who hope to become biologists has increased," said Taruma Akinori, who is in charge of the science course.

    In addition to the results being added to the scientific community, the students’ research paper will be translated into English and made available overseas. Moreover, the students have decided to take on a new challenge in DNA decoding.
