Climate change threatens Africa
Climate change in Africa gave rise to modern humans. Now experts fear that global warming linked to carbon emissions will have its worst impact on
humanity's cradle. "Africa is the most vulnerable continent to climate change," said Jennifer Morgan, director of the Global Climate Change Programme at conservation group World Wildlife Fund.
Bird flu found in Japanese chicken
A type of bird flu virus has been detected at a chicken farm in eastern Japan where hundreds of fowl died earlier this year, a Japanese Farm Ministry spokesman said on Sunday. The virus that was detected was a "weak" form of bird flu, the spokesman said. Kyodo news agency said the strain identified was H5N2, which is less virulent to the H5N1 strain found in
previous avian flu outbreaks in Japan.

Scientists search for probe
US and Russian scientists were looking at launch data on Cosmos 1, the world's first solar-powered spacecraft, keeping up hopes that they might find the missing probe. A submarine-fired Russian rocket that was supposed to lift Cosmos 1 into orbit is believed to have malfunctioned after blastoff, but the fate of the space probe itself was unknown.
South Korean stem-cell researcher honored
The South Korean government named cloning pioneer Hwang Woo-suk as the nation's ``top scientist,'' an honor that will grant him as much as 3 billion won (US$3 million) in annual funding for five years. Last month, Hwang and his colleagues at Seoul National University created the first embryonic stem cells that genetically match injured or sick patients -- a major step in the quest to grow replacement tissues to treat diseases. A year ago, Hwang's team created the world's first cloned human embryos.
