J-Innovators:
A Lifeboat Launched from 30 Meters Up

A boat that looks like a submarine? It might be funny looking, but it's actually a lifeboat! Reporter Michelle Yamamoto visits the innovator who developed a lifeboat that is capable of launching from 30 meters above the ocean. Boats like these are used when a crew has no alternative but to abandon ship as quickly as possible. But launching from so high up, means the boat has protect its passengers from the impact of hitting the ocean. The innovator spent three years trying all different designs before he finally found a solution. Join Michelle, as she meets the man behind this innovative lifeboat.

Science News Watch:
Invasive Species Found in Mainland Japan

Kamikochi in Nagano Prefecture is known for its beautiful natural spaces. The view from Kappabashi bridge is an especially popular tourist destination, drawing visitors from around the world. This week, our focus is on an unwelcome change to the Kamikochi ecosystem. An Environment Ministry survey has found a foreign species, Rudbeckia laciniata, known as coneflower, near the Taishoike Lake. How did it get there? What can be done to stop it? Other popular tourist destinations around the world are dealing with similar problems. Science watcher Katsuyuki Sakai takes a closer look.

The Leading Edge:
How Buildings Handled Japan's 2011 Megaquake

Scenes of the ceiling collapsing in the Ibaraki Airport lobby were some of the first images shown on TV after the Great East Japan Earthquake of 2011. The ceiling was made of heavy plaster board. Anyone struck by them would have been badly injured. What caused the ceiling to fall? Analysis has revealed an unexpected weakness. This kind of suspended ceilings is commonly used in all kinds of public buildings. Professor Kenichi Kawaguchi of the University of Tokyo joins us in the studio to talk about improving building safety during earthquakes. Be sure to tune in!
