The article reports on the inquiry of a research team led by Tae Kook Kim of the Korea Advanced Institute of Science and Technology (KAIST) in Taejon on two articles published in "Science and Nature Chemical Biology" on imaging living cells. Tae Kook Kim reported a new method for imaging living cells that used magnetized nanoparticles. KAIST's investigation is still going but has released some preliminary findings that the scientific truth of the papers was in question. The journal's editor said that the KAIST investigation team told him that the authors wanted to pull back the paper as soon as possible.
