J-Innovators:
A Pot that Cooks Food without Water.

We report on a pot that is so popular there is a 15-month waiting list for it. It looks like an ordinary cooking pot, but when you use it, you don't need to add any water before cooking your food. Reporter Michelle Yamamoto tries it out with a pot-au-feu. She adds no water at all, yet the finished stew emerges rich and flavorful, with plenty of broth. The key is how tightly the lid fits on the pot-the ridges on the pot's surface are less than one hundredth of a millimeter. The two Takumi who make these pots are brothers, and they inherited their factory from their father, who struggled due to price competition and economic slowdown. The Takumi resolved that they would bring a new product to market, one that would make the best use of the craft skills and equipment their company already had. We report on the R&D secrets that gave birth to this super-popular pot.

Uncovering the Secret of Longevity

Many people would love to stay young and healthy forever. Science Watcher Eiji Mizushima's eye was drawn to an international project aiming to discover the secrets of long life. 250 people turning 100 this year have been chosen from Japan, France, Denmark, Sweden and Switzerland, five countries known for their long life expectancies. These centenarians are participating in interviews and genetic studies. What secrets are being uncovered? Tune in to find out.

The Leading Edge:
What Caused Japan's 2011 Mega-tsunami?

The gigantic magnitude-9 earthquake that struck Japan on March 11, 2011, also unleashed an enormous tsunami that reached as high as 38 meters along the country's eastern coast. A seabed survey conducted off the Sanriku Coast in August 2011 discovered a surprising phenomenon. It is now being suggested that if widely expected earthquakes strike various regions of Japan in the future, this same phenomenon could produce more huge tsunami, and compound the damage wrought by these earthquakes. We introduce the newly understood mechanism behind mega-tsunami.
