J-Innovators:
The World's First Plaster Ceramics

Are you familiar with plaster? It is the stuff artists spread on walls and paint on when making frescoes. In Japan, white plastered walls are associated with castles like those at Himeji and Osaka and also traditional houses. We introduce an artisan who has broken away from 5,000 years of tradition that says that plaster must be made with water. He uses a bold and simple waterless method to make plaster ceramics. By doing so, typically crumbly plaster becomes a sturdy house building material! How is it made? You'll have to watch to find out!

Science News Watch:
Embryonic Stem Cells Help Monkeys with Parkinson's

Science watcher Katsuyuki Sakai focuses on news about the use of human embryonic stem cells to relieve symptoms of Parkinson's disease in monkeys. This groundbreaking work was conducted by a research group from Kyoto University. Some of the monkeys in the study are now even able to walk again. Nearly 4 million people around the world suffer from Parkinson's disease, but there is still no cure. The disease causes shaking and makes movement difficult. This treatment is still in the animal experimentation stage but neuroscientist Sakai hopes that the tests will lead to human clinical trials.
Professor Takuya Ueda of the University of Tokyo has developed this protein synthesis kit.
Professor Tetsuya Yomo of Osaka University has found differences in self-replication capabilities between RNA molecules that should be the same.

The Leading Edge:
Artificial Cells: Revealing the Secrets of Life

Scientists hope to change medicine for the better through creating artificial cells. For example, artificial cells could be used to help heal injured or diseased body organs. Studies on artificial cells are now surging forward in Japan. But how are they made? And what defines a cell in the first place? How similar do artificial and natural cell have to be to be considered living cells? Though there are still huge challenges ahead, scientists are striving to understand the very essence of life!
