A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate.

The body mass index (BMI) is a heuristic proxy for human body fat based on an individual’s weight and height. BMI does not actually measure the percentage of body fat. It was devised between 1830 and 1850 by the Belgian polymath Adolphe Quetelet during the course of developing “social physics”. Body mass index is defined as the individual’s body mass divided by the square of his or her height In addition to the many risk factors associated with poor health, reducing body mass index (BMI) will have a considerable and independent impact if you want to reduce the risk of developing ischemic heart disease (IHD). This is the key finding from new research, published in PLoS Medicine, which evaluated the causal relationship between BMI and heart disease in 76,000 individuals.

A new study has some reassuring news about how fast Greenland’s glaciers are melting away. Greenland’s glaciers hold enough water to raise sea level by 20 feet, and they are melting as the planet warms, so there’s a lot at stake. A few years ago, the Jakobshavn glacier in Greenland really caught people’s attention. In short order, this slow-moving stream of ice suddenly doubled its speed. It started dumping a whole lot more ice into the Atlantic. Other glaciers also sped up. “Some people feared if they could double their speed over two or three years, they could keep doubling and doubling and doubling and reach very fast speeds,” says Ian Joughin of the University of Washington’s Polar Ice Center.

Spring time is here and a lot of people are indulging in gardening. But did you know that there are a lot of chemicals that may be harmful to your health in your gardening supplies? According to Ann Arbor-based Ecology Center, high amounts of lead, phthalates and the toxic chemical BPA were all found in the water of a new hose after it sat outside in the sun for just a few days.

A study by the Wildlife Conservation Society documents that intense development of the two largest natural gas fields in the continental U.S. are driving away some wildlife from their traditional wintering grounds.

Maharishi University of Management’s new Sustainable Living Center, which opened recently, has the distinction of being one of the few net-zero energy buildings in the country—it will produce as much if not more energy than it uses. Sustainable Living Center To Be “Net-Zero Energy Building” The building is designed to eventually be completely off the grid, including for water usage and waste treatment, as more funds are available. However, it will initially be connected to the grid, using electricity as needed during extreme weather conditions. At those times when the solar arrays and wind turbine produce more than the building uses, it will feed excess energy into the campus grid for use in other buildings. Annually the building will produce more energy that it will consume.

It doesn’t take an agricultural expert to know that you can’t grow vegetables without water. So it wasn’t surprising that after hundreds of people marching under the banner “Occupy the Farm” took over a University of California (UC) agricultural testing station on April 22, UC officials responded by shutting off water to the site. The next day, a late-season storm brought a half-inch of rain to the San Francisco Bay Area, irrigating the thousands of vegetable starts in the ground and lifting the spirits of the urban farming activists who are determined to save the site from development. Score: Occupiers, 1 – UC administrators, 0. Social change activists in Berkeley, Calif., have always been ahead of the curve. Today, May Day, is the spring reemergence for the Occupy movement as activists around the United States engage in work stoppages, street marches, and various forms of civil disobedience to press their demands for a more equitable economy. The folks with Occupy the Farm got started early. On Earth Day, they marched from Berkeley’s Ohlone Park to a five-acre plot of land in the adjacent bedroom community of Albany. They cut the locks on the gates of the UC-Berkeley and U.S. Department of Agriculture (USDA) field trial plot, pulled up nearly an acre of thick mustard growing there, and got busy working the soil with a pair of rented rototillers. Then, scores of volunteers planted 150-foot rows of lettuce, beans, cucumbers, and leafy greens. By the end of Earth Day, the Bay Area had a new urban farm.

Corals, trees and marine sediments, among others, are direct evidence of the climate of the past, but they are not the only indicators. A team led by Spanish scientists has interpreted records written in Iraq by Arabic historians for the first time and has made a chronology of climatic events from the year 816 to 1009, when cold waves and snow were normal.

How can you make someone eat healthier? College students wishing to eat healthier may want to invest in a clear fruit bowl says a recent article published in Environment and Behavior. The new study found that when fruits and vegetables are within arm’s reach, students are more likely to eat them. Furthermore, making fruit and vegetables more visible increases the intake of fruit, but the same does not hold true for vegetables.

In a single paper in Zootaxa scientists have rewritten the current understanding of lizard biodiversity in the Caribbean. By going over museum specimens of skinks, scientists have discovered 24 new species and re-established nine species previously described species, long-thought invalid. The single paper has increased the number of skinks in the Caribbean by 650 percent, from six recognized species to 39. Unfortunately, half of these new species may already be extinct and all of them are likely imperiled. “Now, one of the smallest groups of lizards in this region of the world has become one of the largest groups,” co-author Blair Hedges with Penn State University said in a press release. Hedges and his team determined the new species through morphological research as well as DNA studies.
