Robert Siegel speaks with Dr. Anton Ivanov, a scientist with the Swiss Space Center, about the CleanSpace One project. A team of scientists, including Ivanov, is developing a "janitor" satellite, which will remove debris now orbiting in space.
Toddler formula and other organic rice products have surprisingly high amounts of arsenic, according to a new study. But since there's no federal standard for arsenic in food, it's impossible to say how much is OK.
The United States and five other nations are embarking on a new program to limit pollutants connected to global warming. But they're not targeting carbon dioxide with this effort — instead, they're looking at methane gas, and soot.
The highly-anticipated gathering of flu experts has been described as a fact-finding session that will focus on understanding how bird flu studies done at Erasmus Medical Center in the Netherlands and at the University of Wisconsin were performed and overseen by the relevant authorities.
The wind power industry in this country has grown fast in recent years, but that could come to a screeching halt if Congress doesn't renew a tax credit that wind farms get for the power they produce.

Scientists working with bird flu recently called a 60-day halt on some controversial experiments. The unusual move has been compared to a famous moratorium on genetic engineering in the 1970s. Key scientists involved in that pause on genetic research disagree on whether today's furor over bird flu is history repeating itself.
