Is It Safe To Use Compost Made From Treated Human Waste?

Originally published on Wed May 15, 2013 10:46 am

Any gardener will tell you that compost is "black gold," essential to cultivating vigorous, flavorful crops. But it always feels like there's never enough, and its weight and bulk make it tough stuff to cart around.

I belong to a community garden in Washington, D.C., that can't get its hands on enough compost. So you can imagine my delight when I learned that the U.S. Composting Council was connecting community gardeners with free material from local facilities through its Million Tomato Compost Campaign.

Two astronauts went on a last-minute spacewalk Saturday to replace a pump suspected of being the source of a serious ammonia leak.

It was unclear what caused the ammonia leak, NASA spokesman Rob Navias said, "but the installation of this spare pump package — at least at the moment — seems to have done the trick."

Astronomy's Little Secret: The Hidden Art Of 'Moonsweeping'

La Luna

A few nights ago, (Wednesday, I think, around midnight), I was by my window looking up, and there, hanging in the sky, I saw the moon. Not all of it, just what the almanac used to call "a crescent" — what my mom called a "toenail moon." The whole moon, I knew, was up there, hidden in shadow. The crescent part was facing the sun.

Scotty Miller, I remember, got to hold the tennis ball. Mrs.
