Research led by Hiromi Shiraishi, researcher at Chuo University, has revealed that, in addition to Japanese Eel (Anguilla japonica), American Eel (Anguilla rostrata) is now widely distributed in processed eel products sold at retail stores across Japan. While eel farming in Japan relies primarily on Japanese Eel, two-thirds of eel consumption in the country depends on imports of live adult eels and eel products, which include several species of anguillid eels. As the world’s largest importer and consumer of eel, Japan is in a position to contribute to the sustainable use of anguillids beyond Japanese eel.

Tokyo, Japan – Researchers from Tokyo Metropolitan University have created a new way of telling “aged” human cells apart from younger ones using electric fields. While key markers have been found for these “senescent” cells, current methods require biochemical “labels” which are difficult to apply and affect the cells themselves, making them difficult to study. The new method is label-free and less damaging. The team aims to diversify the method, extending it to other cell types.

New research indicates reef passes — channels that cut through coral reefs and serve as conduits for ocean water and nutrients — are shaped by island rivers.
