EPA reviews hints of weed killer’s fetal risks
The Environmental Protection Agency will be convening meetings of its Scientific Advisory Panel on pesticides throughout 2010 to probe concerns about the safety of atrazine, a weed killer on which most American corn growers rely. The first meeting of these outside experts started Tuesday. And although a large number of studies have indicated that atrazine can perturb hormones in animals and human cells — and might even pose a possible risk of cancer amongst heavily exposed people, these outcomes were not the focus of EPA’s review Tuesday. Risks to babies were.

Giant snakes warming to U.S. climes
Some were pets whose bodies and appetites apparently got too big for their owners to support. Most are probably descendants of released pets. Today, thousands of really big non-native snakes — we’re talking boa constrictors, anacondas and pythons — slither wild in southern Florida. And there’s nothing holding them in the Sunshine State. Which is why a report that was released today contends they pose moderate to high ecological threats to states on three U.S. coasts. Indeed, the homelands of these snakes share climatic features with large portions of the United States — territory currently inhabited by some 120 million Americans. Based on comparisons of the temperatures, rainfall and land cover found in the snakes’ native range, it’s possible that these slithering behemoths could stake claims to territory as far north as coastal Delaware and Oregon.

Not Your Ordinary Amphibians
They resemble mondo worms or perhaps eels and snakes. But caecilians (seh sil yenz) are actually legless amphibians, and along with deep sea fishes are among the least well known vertebrates on the planet. Some run to a meter or more in length. Although information on these elusive animals and photos of them are hard […]
