J-Innovators:
DVD's Restored to Perfection
Most people probably have old DVDs lying around that are too scratched to play properly. This week's J-Innovator has devised a way to repair that damage and make DVDs playable again. He uses sandpaper to grind the surface, but don't worry; none of the DVD's data will be lost. Just two thousandths of a millimeter is carefully ground down and the DVD is as good as new. Tune in to see the machine in action! Michelle Yamamoto reports on the company that makes the machine. It's so successful that it makes over 90% of optical disc restoration equipment sold today.

Fukushima Daiichi: The New Role of Robots
Science watcher Koichi Kitazawa brings us news about a compact robot that will assist in the decommissioning of Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station. Previously we featured the robot Quince, which was developed by the Chiba Institute of Technology for use in nuclear power stations. Quince, however wasn't able to pass through narrow spaces. The same institute has now developed a new robot called Sakura that specifically overcomes this limitation. It's only two thirds the size of Quince. It also has a special feature the limits radiation exposure for its human operators. Can you guess what the feature is? Join us to find out more about how this robot has been improved for its vital mission to dismantle nuclear reactors!

Artificial Photosynthesis: Power to Change the World
Photosynthesis is the process by which plants obtain energy from sunlight. Scientists have long tried to artificially replicate this process. If they succeed, it could have a major impact on both energy production and our way of life. In fact, in 2011, Japanese scientists made a breakthrough discovery in the field of artificial photosynthesis. They pinpointed the structure of an enzyme that was a mystery for 200 years. The research project began 20 years. It also discovered a surprising feature of the enzyme's structure. Researchers are also using the science behind photosynthesis in an effort to use light energy to extract hydrogen from water. This research makes use of a material with astonishing properties. Can you guess what material they are using? Join us for an in depth look at latest efforts to realize artificial photosynthesis.
