In the present study, a group of Rikkyo University researchers led by Assistant Professor Takahito Mukai and Professor Masayuki Su'etsugu has succeeded in splitting the E.coli genome into tripartite-genome of 1 million base pairs per geno...

New Laser Technique Shows Smog-Forming Effects of Nitrophenol in Air Written by AZoOpticsFeb 4 2021 A new, sophisticated laser-based technique has enabled scientists to observe the live decomposition of a pollutant into atmospheric nitrous acid, which plays an essential role in the development of photochemical smog and ozone. Extreme ultraviolet femtosecond pulse light source and photoelectron spectrometer, key instruments used in the experiment. Image Credit: Taro Sekikawa. As explained by Hokkaido University scientists in The Journal of Physical Chemistry Letters, the new technique could f...

Hokkaido University scientists show that under laboratory conditions, ultraviolet light reacts with nitrophenol to produce smog-generating nitrous...

Credit: Takashi Matsubara A research group led by Associate Professor YAGUCHI Takaharu (Graduate School of System Informatics) and Associate Professor MATSUBARA Takashi (Graduate School of Engineering Science, Osaka University) have succeeded in developing technology to simulate phenomena for which the detailed mechanism or formula are unexplained. They did this by using artificial intelligence (AI) to create a model, which is faithful to the laws of physics, from observational data. It is hoped that this development will make it possible to predict phenomena that have been difficult to simu...
