Ohio State Glaciologist Team Gets Important Ice Cores in Andes
November 3, 2009 06:46 AM - Roger Greenway, ENN

Ice cores are important tools to identify Earth’s past climate. They enable us to peer back in time to identify species of insects trapped in ice as well as isotopes oxygen and dust particles that were deposited at various time in the past. The ratio of oxygen isotopes in the ice allows researchers to determine whether temperatures were warmer or cooler when the snow that eventually turned to ice was deposited on the glacier. The dust content gives scientists clues about the rate of precipitation at the site. The thicker the core (longer cores) the longer into the past we can see.

Unanticipated Long Term Consequences of Nuclear Waste From Bomb Making
November 1, 2009 09:50 AM - Frank Clifford, L A Times

Radioactive debris has been found in canyons that drain into the Rio Grande, but officials at the Los Alamos National Laboratory say there's no health risk. More than 60 years after scientists assembled the nuclear bombs dropped on Hiroshima and Nagasaki, lethal waste is seeping from mountain burial sites and moving toward aquifers, springs and streams that provide water to 250,000 residents of northern New Mexico. Isolated on a high plateau, the Los Alamos National Laboratory seemed an ideal place to store a bomb factory's deadly debris. But the heavily fractured mountains haven't contained the waste, some of which has trickled down hundreds of feet to the edge of the Rio Grande, one of the most important water sources in the Southwest.

Side effect of plastic: Aggressive Kids

Plastics containing Bisphenol-A linked to child misbehavior Yes we know, everything causes cancer, nothing is safe for our kids, a lot of paranoia, right? Sometimes these concerns are for real. A chemical of significant importance to parents and scientists these days is Bisphenol-A (BPA). BPA is a common chemical used in plastics for increased flexibility and molding. It can be found in your child’s plastic sippy cup, binkies, and even canned food. The lining found inside some canned foods is very similar to high density plastics, thus likely to contain significant levels of BPA. Numerous studies have proven that BPA can negatively impact your health. Experts have advised people to shop for BPA-free products. In general, avoiding plastics whenever possible is a good idea.

Drilling Deep Into Controversy

Just when you think all human activities are making the environment worse, news comes that our efforts to improve efficiency and reduce environmental impacts (0ur environmental footprint) are doing some good. According to a new U.S. Geological Survey report, the U S is using less water now than during the peak years of 1975 and 1980, despite a 30 percent population increase during the same time period.
