It's not just football players or troops who fought in the wars who suffer from brain injuries. Researchers estimate that hundreds of thousands of ordinary people in the U.S. get potentially serious brain injuries every year, too. Yet they and even their doctors often don't know it.

One such doctor is Bryan Arling, an internist in Washington, D.C. His peers often vote to put him on those lists of "top doctors," published by glossy magazines.

Bernard Valencia's room in the Jerry L. Pettis Memorial Medical Center in Loma Linda, Calif., illustrates how hospitals across the country could fight a nationwide epidemic. As soon as you enter the room, you can see one of the main strategies: A hook hangs from a metal track that runs across the ceiling.

This isn't some bizarre way of fighting hospital-acquired infections or preventing the staff from getting needle sticks. The contraption is a ceiling hoist designed to lift and move patients with a motor instead of muscle.

There are two important things that you learn about Michael Zusman, baker and co-author of The Artisan Jewish Deli at Home, when you bake with him.

First, his real job has nothing to do with bread or writing recipes: He's a trial judge. "Full time," Zusman says. "Wear a black robe every day."

You might think that everything would have changed for the chemicals industry on April 16, 1947. That was the day of the Texas City Disaster, the worst industrial accident in U.S. history. A ship loaded with ammonium nitrate — the same chemical that appears to have caused the disaster last month in West, Texas — exploded. The ship sparked a chain reaction of blasts at chemical facilities onshore, creating what a newsreel at the time called "a holocaust that baffles description."

If you've applied for a mortgage recently, you know how hard it can be. The bank demands all kinds of obscure documents and wants proof of almost every asset you own. But an innovative mortgage program halfway around the world will evaluate your application without any extra documentation — and if you're approved, it will give you a 15-year fixed-rate mortgage.
