Now showing: Map that gave America its name

Five centuries ago, a maker of woodblock-print maps who lived in a small French cathedral town chiseled out the letter "A" in an area of the map that's now Argentina. "M" was his next letter, followed by E-R-I-C-A. | 02/26/08 14:12:00 By - Frank Greve

American pumps up Third World farmers' income

If there's a limit to what one person can do about Third World poverty, Paul Polak hasn't found it.

The doorknob's days are numbered. The compelling argument for door levers is a practical one: When you're struggling with too many bags or with arthritis, the lever's easy-release mechanism sparks a little gratitude. Heck, an elbow works when your hands are full. | 12/27/07 06:00:00 By - Frank Greve

Even doctors believe some health myths

Just because your doctor tells you to drink eight glasses of water daily doesn't mean you should, according to researchers at the Indiana University School of Medicine. Doctors often fall for the same health myths that their patients do. | 12/21/07 15:22:00 By - Frank Greve

The new key question: How happy are you?

Is it time to offer day care for ailing older parents to give their care-giving children a break? Time for much bigger incentives for carpooling? Time to extend maternity and paternity leave substantially? | 11/24/07 06:00:00 By - Frank Greve
