Antiretroviral regimens drastically reduce breast milk HIV transmission between mothers and babies

Scientific American Online - Wed, 2010-06-16 22:50

HIV infects an estimated 430,000 infants and children worldwide each year. Although many of those cases are contracted from an HIV-positive mother during pregnancy or birth, some 40 percent of infected children get the disease through breast-feeding . But because of health risks associated with formula feeding--especially in resource-poor regions--the World Health Organization still recommends breast-feeding for mothers with HIV/AIDS in the developing world. Left untreated, however, about half of HIV-infected infants die before the age of two. [More]

The Green Apple: How Can Cities Adapt to Climate Change?

Scientific American Online - Wed, 2010-06-16 22:01

NEW YORK CITY--Here is how climate change could shut down a city: On the morning of August 8, 2007, a thunderstorm paralyzed the largest rail transit system in the U.S.--New York City's subway--during morning rush hour. Flash floods deposited more than 7,000 kilograms of dirt and debris on tracks that stretch more than 1,350 kilometers and carry 1.5 billion passengers annually. A December 1992 storm had a similar impact, including flooding portions of Lower Manhattan and the East River Drive. [More]

Deepwater spill survey: Sampling water columns under a night sky lit up by a large jet of burning methane

Scientific American Online - Wed, 2010-06-16 19:45

Editor's Note: A team of researchers led by John Kessler , Texas A&M College of Geosciences chief scientist and assistant oceanography professor, has traveled to the Deepwater Horizon disaster area to study the methane leaking into the Gulf of Mexico (along with tens thousands of barrels of crude oil) daily at the site of the damaged Macondo 252 well. Kessler, along with David Valentine (an assistant professor of marine sediment geochemistry, biogeochemistry and geomicrobiology at the University of California, Santa Barbara) and the rest of his colleagues are hoping to come away with a rough estimate of the spill's size by the time his team returns home on June 20, followed by more accurate estimates as they complete their analysis of the information collected. Other objectives of the expedition onboard the RV Cape Hatteras include trying to determine how the methane might be removed from the water (whether eaten by waterborne microorganisms or released into the atmosphere) and how methane concentrations will change over time. Valentine filed the following dispatch. It's the team's third blog post for Scientific American.

On June 15, the Kepler team released information on possible planets identified in the first month or so of the spacecraft's three-plus-year mission--a massive set of more than 300 candidates that promises to significantly augment the known catalogue of extrasolar planets. The data were published online at the preprint repository arXiv.org and will be submitted to The Astrophysical Journal . [More]
