TP execs: Americans don’t create enough waste in the bathroom

It takes tens of thousands of trees to create the amount of toilet paper that’s used every single day. But in the minds of corporate executives, Americans, at least, aren’t using enough paper during their bathroom routine.

The three cities with the most air pollution in the country are all in California, but L.A. only comes in third. A couple of inland metro areas come in first and second.

Scientists use glow-in-the-dark fish to track hormone-disrupting chemicals

Imagine if your body could tell you where and when a certain chemical is impacting your health. Scientists at the University of Exeter have done just that – with green-glowing zebrafish, that is. Researchers genetically engineered young zebrafish to produce a fluorescent glow in the presence of hormone-disrupting chemicals like bisphenol-A. By exposing fish to endocrine disruptors and observing when individual body parts light up, researchers can learn exactly how and at what concentrations these chemicals impact various organs and tissues. They can then make certain inferences on how endocrine disruptors impact human health. For instance, observing the glowing fish …
