A team of researchers from Hiroshima University in Japan have developed a non-invasive way to test inflammation in drug testing that would not involve killing lab animals.
Recycler Jeplan is working to extract cotton fiber from used apparel and convert it to fuel. Jeplan says 1 ton of junked clothing can generate about 700 liters of ethanol, sparing land and water resources that could be used to grow food. The company says it’s also developed a way to recycle polyester. That compound is blended into many fabrics to reduce costs, improve durability, and make outfits wrinkle-resistant. It’s used in about 60 percent of the clothing produced worldwide each year, according to Jeplan, and can be a valuable resource when broken down and reused in new clothing.
Every year, Japan undertakes what it has labeled as a scientific hunt for whales in the Southern Ocean. However, in 2014, the International Court of Justice ruled Japan should stop. Instead, Japanignored the ruling last year and announced it would continue whaling while reducing the number of whales it would kill by two-thirds to 333.
On Thursday, Japan’s Institute of Cetacean Research detailed that out of the 333 minke whales it killed, 230 were females, and that more than 90 percent of those were pregnant.
The future of Japan’s biofuel industry may be pond scum. Or more specifically, green algae that’s swirling around in tanks on a tropical Okinawan island.
Japan’s campaign to boost renewable power supplies since the Fukushima nuclear disaster is producing some unlikely winners: vegetable farmers.
Makoto Takazawa and his father Yukio earned 1.7 million yen ($16,700) last fiscal year selling electricity from solar panels that hang in a giant canopy above their farm east of Tokyo. The cash was almost nine times more than they made from the crops growing in the soil below.
Under pressure from trade partners to reduce agricultural subsidies, Japan has found a way round this by giving clean energy subsidies to farmers instead.
