J-Innovators:
An Innovative New Kind of Code

There is an art museum in Hakone that has talking guide pamphlets. Just touch a special pen to a photograph of an artwork, and you'll hear a description of the artwork in question. How does it work? Michelle Yamamato ventures to Akihabara, Japan's most famous electronics district, to meet the Takumi, or innovator, who developed the technology. The Takumi calls his innovation a "dot code," and it is being used not just in museum pamphlets, but also in teaching materials and sales catalogues. The secret lies in the pamphlet's surface -Michelle takes a closer look with the help of some special hardware. Today's Takumi is a former university professor who aims to bridge the digital and analogue worlds. Tune in to find out more about his innovative technology.

Science News Watch:
Measuring Radiation Quickly and Easily

Science Watcher John Gathright was interested in a quick new method of gauging radiation exposure. Say a group of people is exposed to radiation in a nuclear accident, and you want to find out just how much radiation they've been exposed to. The conventional method -taking blood cell samples and looking for chromosomal abnormalities- takes close to ten hours, and requires scientific expertise. But this new method can measure radiation exposure in just two or three hours, and it can be used even by non-experts. It was developed by Professor Satoshi Tashiro and his team at Hiroshima University. What is this amazing method? Watch and find out.

The Leading Edge:
IKAROS: The World's First Solar Sail Spacecraft

With IKAROS (the Interplanetary Kite-craft Accelerated by Radiation Of the Sun), the Japanese space program has amazed the world. IKAROS is the world's first spaceship that can fly about freely in space without a mechanical engine. It's like something out of science fiction. How exactly does IKAROS propel itself? The idea behind IKAROS was first conceived by a U.S. research institution a century ago, but it took uniquely Japanese talent to make it a reality -actually, origami was a crucial source of inspiration for the engineering team. Now, a new, larger craft modeled on IKAROS is being designed to explore our solar system. It is expected to take flight in 2020. IKAROS is promising to change the shape of space exploration.
