Rubin Observatory peers into the ‘hidden universe’ and discovers stream of stars longer than our entire Milky Way

“We are expecting that when Rubin obtains very deep imaging of galaxies, we will see them surrounded by a faint network of stellar streams,” Romanowsky concluded. “The discovery of the stream shows the excellent characteristics of Rubin for making such observations, and points to a rich future of similar discoveries as vast areas of the sky are mapped out.”

Carbon electrode enables 1-Wh-class stacked lithium-air battery with enhanced output and lifespan

A joint research team from NIMS and Toyo Tanso has developed a carbon electrode that enables stable operation of a 1-Wh-class stacked lithium-air battery, achieving higher output, longer life and scalability simultaneously.

The team created this electrode by combining manufacturing technology that Toyo Tanso developed for its “CNovel” porous carbon product with proprietary technology NIMS developed to fabricate self-standing carbon membranes.

This combination made it possible to scale up the battery cell size—a significant step toward practical, industrial-scale lithium-air batteries. The research was published online in Cell Reports Physical Science on September 18, 2025.
