The number of wild Yangtze alligators could more than double during the next five to 10 years, an alligator expert in China said Sunday. Wang Chaolin, Chinese Alligators Protection Nature Reserve deputy director, said while only 120 specimens of the endangered alligator species exist, an apparent increase in their living and breeding territories could help increase their population to 300 within 10 years, China's state-run news agency, Xinhua, reported. Wang, whose wildlife reserve is located in China's Anhui Province, said the predicted increase is also based on the discovery of wild baby alligators in China.

By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds.
A collaboration between more than 70 researchers across the globe has uncovered nine new genes on the X chromosome that, when knocked-out, lead to learning disabilities.
British scientists say they have developed a stem procedure that will reverse the most common cause of blindness, age-related macular degeneration. The procedure, pioneered by the Institute of Ophthalmology at University College London and Moorfields eye hospital, involves replacing a layer of degenerated eye cells with new ones obtained from embryonic stem cells, The Sunday Times of London reported. The newspaper said pharmaceutical research company Pfizer this week will announce financial backing to bring the therapy to patients. This is a huge step forward for patients, Tom Bremridge, chief executive of the Macular Disease Society, told The Sunday Times.
