We interviewed Senior Researcher Kobayashi Takumi of the Time Standard Research Group, Research Institute for Physical Measurement, National Metrology Institute of Japan (NMIJ), whose work earned the AIST Paper Award. More information:

Research in the field of metrology that accurately checks the definition of second, supports everything from the world’s infrastructure to the future science.

Time is an important social infrastructure that is shared by people worldwide. As research progresses in various countries towards the realization of the redefinition of the second, we have achieved high uptime operation of optical lattice clocks using new technology.

Long-term sediment decline causes ongoing shrinkage of the Mekong megadelta, Vietnam Tamura T., Nguyen V.L., Ta T.K.O., Bateman M.D., Gugliotta M., Anthony E.J., Nakashima R., Saito Y., Scientific Reports 10, 8085 (2020).

We interviewed Chief Senior Researcher Tamura Toru of the Paleogeodynamics Research Group, Research Institute of Geology and Geoinformation, who received the AIST Paper Award for this research. More information:

While measures are urgently needed, research using geological dating technology has revealed the process of the formation and erosion of the Mekong Delta.

Geology is the key to solving future problems by unraveling the Earth's past environment. The Mekong Delta spreads out at the mouth of the Mekong River in southern Vietnam. Coastal erosion is becoming more severe, causing coastal villages to disappear and farmland to flood.
