"The Genetics History of the Ryukyuans" by Professor Johannes Krause

Ancient and modern population genetic studies have recently shown that present-day Japanese populations originated by a mixture of two distinct gene pools, one related to the rice-farming Yayoi culture and the other related to the pre-Yayoi Jomon culture.

Present-day Ryukyuans, including those from southern-most Miyako and Ishigaki islands, share this genetic composition with mainland Japanese, with higher contribution from the Jomon-related gene pool, but this composition is clearly distinct from that of indigenous populations from Taiwan.

Prof. Krause explains how investigations into ancient genomes from Miyako-jima have shed light on when this this sharp genetic boundary developed.

This is the introduction movie of Open Energy Systems which are installed in 19 OIST faculty houses. Each house is connected with DC cable lines and exchange energy each other.

Higher Order Mode Video

This video shows a polystyrene particle propelled along a microfiber by light, first in the fundamental mode, then in a higher order mode. It is easy to see how much faster the particle zips along in the higher order mode.

STEPS - Visualization toolkit

In the upper left box you can see all parts of the neuron in this model, the external structure and internal compartment (ER) that holds calcium (yellow), and the proteins involved in opening the calcium channel (blue, bright magenta and dark magenta). In the other boxes, you can see the calcium or each protein separately to watch their movements and activation. In the bottom center, you can see the numerical data in real time as the model runs.
