Dynamics of a fish-killing dinoflagellate Karenia mikimotoi red-tide captured by composite data sources.

In this study, controlling factor of a horizontal expansion of a fish-killing Karenia mikimotoi red-tide was clarified in the Yatsushiro Sea using multiple data sources. The backscattering data of the current meter captured the modulation of DVM (shallowing of the night distribution). It was suggested that the horizontal expansion of the bloom was driven by the strong surface current and the modulation of DVM.

In April 2023, UK based organization [Braintastic! Science](*1) piloted their new show for children, Amazing Animals, at the Edinburgh Science Festival, featuring the work of Professor Toshiyuki Nakagaki. During the show, founder and presenter Ginny Smith introduced the families to the amazing cognitive abilities of animals including crows, chimps and dolphins as well as the surprising puzzle-solving skills of the humble slime mould. The audience were challenged to solve a simple maze, and to connect the Tokyo area subway map, before seeing the slime mould’s solutions, and hearing about how effectively they can solve puzzles like this, despite not having a brain! The show was received really well, and Braintastic! Science now plan to add it to their repertoire, taking it to schools and festivals around the UK and (occasionally) elsewhere, sharing the amazing abilities of the slime mould, and the work of the Professor Nakagaki group, with a wide and diverse audience.

Titles: Nonlinearly interacting entrainment due to shear and convection in the surface oceanAbstracts: This study reveals that sheared flow and convection nonlinearly interact in the ocean surface mixed layer, resulting in reduced entrainment of water from below the mixed layer. Overestimated mixed layer depths seen in many ocean general circulation model simulations may likely be ascribed to inappropriate representation of this nonlinear interaction by those models.

Professor Toshiyuki Nakagaki (Research Group B02-1) and his group's research was introduced in the second volume of the book "Let's Talk about Disability! - Disability and Welfare as Considered by 'Kotonone'" edited by Kikuo Satomi, published on October 30, 2021. "Brainless slime mold solves the maze”, pp. 205-219. The research was introduced in the form of a dialogue with the editor Mr. Satomi.
NHK BS World Documentary "Slime mold: Genius without a brain" was aired (rebroadcast). In this documentary, Professor Nakagaki's laboratory was introduced as one of the world's masters of slime mold. This documentary was produced by ARTE France/Hauteville Productions and broadcasted in France and other countries, but NHK translated it into Japanese and broadcasted it.
"Slime molds," single-celled organisms that have characteristics of both amoebas and fungi, are now attracting attention in the world of science. The film depicts the forefront of research to utilize the "intelligent" properties of slime mold, which has no brain or nerves. One of the "intelligent" properties of slime mold is the ability to find the route to the exit of a maze in the shortest distance. One of the "intelligent" properties of slime mold is its ability to find the shortest route to the exit of a maze, and a scientist who used slime mold to create an efficient railroad map of the Tokyo metropolitan area won the Ig Nobel Prize. There are also hopes for the use of slime mold in medicine, environmental issues, and even in the development of bio-computers. The film depicts the forefront of research, including the eerily beautiful growth of slime mold, as well as B-grade horror film footage using slime mold as a motif.
