Florida-based Lighting Sciences Group Corp., whose Satellite Beach factory specializes in LED lighting, and Osram Sylvania, a unit of Germany's Siemens AG, will show several 100-watt-equivalent prototypes that can replace traditional "incandescent" - and energy-guzzling - 100-watt light bulbs that are set to disappear from stores in January under a law Congress passed a law in 2007. Their demonstrations at the LightFair trade show in Philadelphia this week mean that brighter LED bulbs will likely go on sale next year. The new bulbs will cost about $50 each, and some consumers may hoard traditional bulbs. The latterwaste most of the electricity that feeds them, turning it into heat, but cost much less. Conventional bulbs rated 40 watts and higher will start going off shelves in 2014.
World's oldest panda dies at 34
Chinese state media say the world's oldest panda has died at the age of 34. The Global Times reported that Ming Ming, who had been living at a zoo or preserve in Guangdong province, had kidney failure. The China Panda Protection Center in Sichuan province said she died May 7, but it was reported only Tuesday in local media. Giant pandas are among the world's most endangered species, with about 1,600 in the wild. More than 300 are in captivity in China.
Pregnant panda? Scientists at the National Zoo in Washington said they have detected a rise in hormone levels in the giant panda Mei Xiang that could indicate she may give birth or end a false pregnancy by early July.
