The Los Angeles Times reports U.N. steeply lowers its AIDS estimates. “The United Nations on Monday radically lowered years of estimates of the number of people worldwide infected by the AIDS virus, revealing that the growth of the AIDS pandemic is waning for the first time since HIV was discovered 26 years ago. The revised figures, which were the result of much more sophisticated sampling techniques, indicate that the number of new infections peaked in 1998 and the number of deaths peaked in 2005. The new analysis shows that the total number of people living with HIV has been gradually increasing, but at a slower rate than in the past.”

According to the The New York Times, scientists Through genetics are tapping a tree’s potential as a source of energy. “Aiming to turn trees into new energy sources, scientists are using a controversial genetic engineering process to change the composition of the wood. A major goal is to reduce the amount of lignin, a chemical compound that interferes with efforts to turn the tree’s cellulose into biofuels like ethanol… Environmentalists say such work can be risky, because lignin provides trees with structural stiffness and resistance to pests. Even some scientists working on altering wood composition acknowledge that reducing lignin too much could lead to wobbly, vulnerable trees.”

The Guardian reports Hispanic names make top 10 list in America. “Forget about keeping up with the Joneses. It’s the Garcia, Rodriguez and Martinez families that are the ones to watch. Data from the US census bureau suggests that some surnames of Hispanic origin have supplanted Anglo ones – such as Wilson – traditionally thought of as quintessential American names. In the 2000 census, Garcia was the eighth most common surname in the US, and Rodriguez came in at number nine, both ahead of Wilson, which at 10th was only just ahead of Martinez. It was probably the first time in US history that a non-Anglo name ranked among the top 10 most common surnames.”
