This time we feature a project to build a telescope with a 30-meter mirror. It's called the Thirty-Meter Telescope (TMT) and is being developed by a consortium of five nations, including Japan. Such a large telescope would be impossible without technology to make ultra-high-precision mirrors, and adaptive optics that boost the image resolution even further. We'll meet Japanese scientists and engineers involved in overcoming these daunting technical challenges.

The enormous biodiversity of life on Earth makes the natural world a treasure trove of benefits for humanity. Kevin put his life sciences expertise to work explaining why. An organism from coastal tidepools has yielded a valuable anticancer drug. As an island country, Japan has a long and storied record in marine biology research. Joining forces with Japan's cutting-edge research techniques in analytical and synthetic chemisty, Japanese science brought a new drug from sea to clinic.

How can we predict volcanic eruptions? How can we know about them before they happen? A nation full of volcanoes, Japan has been at the forefront of research seeking to answer these questions. On this program, we learn about instruments that have been placed inside volcanoes to measure their expansion, how magma movements are being measured by minute changes in gravitational pull, and how one cutting-edge experiment is using cosmic particles to peer inside volcanoes. Every improvement in volcano prediction has the potential to save lives. Meet the dedicated researchers who are blazing new trails in this field!
