20 pct of male US bass have 'feminized' by pollution

A study by the US Geological Survey finds 20 percent of male bass in US waterways have egg cells growing in their gonads. (Newsvine) Why? Researchers believe it’s residual from birth control pills and other women’s hormone treatments that make their way into the watershed from sewage systems. Who cares? First, while the fish are still able to reproduce, “they don’t reproduce as well.” Second, “intersex fish are also seen as a general warning about what some experts see as a wider problem of endocrine disruptors in the environment.” In other words, the canary is starting to pass out. We better do something about it.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
