How Green Are Your Travels?

This website offers a rough gauge of the carbon-dioxide emissions associated with flying around the country. Just plug in a starting point and destination and it gives you a round-trip estimate of the greenhouse-gas “footprint” of your travel.

It’s a trait that often signals a critter is toxic, as many of these worms indeed are. Alas, their bright skins are likely not well appreciated by members of their own species, owing to very poor eyesight. […]

Living Rust

Mention rust, and most of us think of the oxidized metal that signals the aging and decay of cars, fences, and bolts on the backyard deck. However, many plants also suffer from rust—in this case, fungal diseases named for their characteristic reddish-orange color. With a particularly virulent example known as Ug99 (see Wheat Warning—New Rust […]
