BLM plows ahead with drilling plans in Colorado

The Bureau of Land Management, having already made the unpopular decision to drill for oil and gas on Colorado’s Roan Plateau, has politely declined Gov. Bill Ritter’s suggestion that it at least explore in phases or avoid certain environmentally sensitive areas. “There are some areas where we cannot meet the desires of the state of […]

EPA closure of research libraries was a stupid idea, says GAO

The U.S. EPA decision to deal with a 2006 funding cut by closing several research libraries was not very well thought out, says a new report from the Government Accountability Office. To take just one example: The EPA promised to compensate for the closures by making information available on the internet, but due to copyright […]

Following the path of contaminants from your bathroom to the birds

This is a story about sludge, worms, and songbirds, and it starts in your bathroom cabinet.

When we treat our wastewater to remove "biosolids" -- a polite term for our human waste -- all sorts of other things end up in the leftover sludge, including the drugs we take and the "personal care products" like lotion, shampoo, makeup, and cologne that we slather on our bodies, which have been absorbed through our skin and then excreted in our waste. The treated wastewater is usually discharged into the local river, and the sludge that's been removed from it frequently becomes fertilizer for agricultural production.

Researchers at the U.S. Geological Survey have found that the hungry earthworms who feed on this sludge in farm fields contain concentrated levels of our drugs and personal care products in their bodies. In fact, a USGS study published in February found that the compounds bioaccumulate in earthworms, meaning that the worms bear higher levels of these pollutants than the surrounding soil does. The USGS researchers note that worms could become monitoring species to help us determine the relative pollution levels in soil, but state that the pollution in these worms have "unknown effects" for wildlife (read the story in Science News).

"Unknown" maybe in that particular study, but researchers in the U.K. published a disturbing study about a week later that provides some insight into what happens to the polluted worms: Birds eat them.

World’s tiger population unwell, WWF says

Photo: Paul Buxton The world’s tiger population is doing poorly and may have been halved in the last 25 years, according to the World Wildlife Fund. The group estimates that the global tiger population has plummeted to about 3,500 today from as many as 7,500 in 1982. Habitat destruction and poaching to feed the thriving […]

Salmon fishing season in California and Oregon may be canceled

So few salmon are swimming in California and Oregon that salmon fishing season is likely to be canceled completely unless an emergency exemption is granted, according to the federal Pacific Fishery Management Council. The states’ salmon season, which traditionally runs from April to mid-November, has never been entirely canceled before. Even with a complete closure, […]

Gulf War syndrome likely caused by chemical exposure, says research

Fatigue, dizziness, rashes, memory loss, and other symptoms of Gulf War syndrome are likely tied to a combination of chemicals that veterans were exposed to during the war, says new research published in the Proceedings of the National Academy of Sciences. The review of studies on Gulf War syndrome supports the theory that pesticides used […]

A fun traffic simulator and lessons learned

Via Brad Plumer: a traffic jam in in a bottle.

To me, it's pretty remarkable how closely the real-world experiment above matches up with this java-based computer traffic simulator.
