| How to do an ongoing energy self-audit Editor's Note: Scientific American's George Musser will be chronicling his experiences installing solar panels in 60-Second Solar. Read his introduction here and see all posts here.I mentioned in my last post that you really need to do energy audits on an ongoing basis. Luckily, you can, without hiring a consultant each time.

Nuclear power could cost trillions over renewables Nuclear power plants may not emit greenhouse gases, but they sure could suck in the tax dollars. [More] Presented By:Review your Credits Reports Once a YearUnder FCRA laws, you are allowed to request your credit reports from Equifax, Experian and TransUnion once every 12 months.

Salmonella wins, food safety bill loses in early House vote Last night, the House of Representatives came up six votes shy of passing a groundbreaking – but flawed – food safety bill. The House plans to give it another shot today.With animal droppings contaminating our spinach with E. coli and bird feces leaving peanut butter with a Salmonella taint, food safety advocates have long urged a reform of our nation’s patchy safety network that regulates the growing, distributing, and processing of foods. In the United States, some 76 million people get food poisoning each year, and 325,000 of those end up in the hospital. [More] rss.sciam.com |
A New Vision for Teaching Science (preview) We face a real crisis in science education in America. Representative Bart Gordon of Tennessee, chair of the House Committee on Science and Technology, has warned that countries such as China and India will trample the U.S. economy in the near future without major improvements in teaching. Indeed, our schools are falling behind. In the 2006 Program for International Student Assessment (PISA)--a respected measure of achievement around the globe--the average science score of U.S. 15-year-olds dropped below that of teens in 28 out of 57 participating countries. (In math, U.S. students fared even worse, lagging behind their peers in 34 nations.)Despite decades of reform, America has made only modest gains in the science classroom, particularly in high schools. Two recent reports from the National Research Council (NRC), however, offer novel strategies. Entitled Taking Science to School and Ready, Set, Science! , they call for changes in the way science is taught beginning in elementary school. Unlike previous recommendations, the new suggestions reflect recent findings from neuroscience and psychology about how young children think and how they acquire knowledge. [More] rss.sciam.com |
Swimmers, Hoppers and Fliers: How Do Toxic Chemicals Move Around the Planet? Editor's Note: The following is an excerpt from Elizabeth Grossman's book Chasing Molecules .Even hundreds of miles from the nearest industrial or agricultural activity, the sea ice, ocean, and Arctic plants and animals regularly yield evidence of elemental and synthetic chemical contamination. This contamination includes not only herbicides, fungicides, and pesticides--chemicals that are used in open air, may have washed directly into rivers or are released from factories--but also metals, among them mercury as well as flame retardants and water repellants, among other substances that are, at least in theory, incorporated into the materials of the products they’re designed to enhance.
