That has led to an experimental drug for the disease that's based on a hormone associated with pregnancy.<p>The hormone is a form of estrogen called estriol. It's abundant in a woman's body only when she is pregnant.

It's another move in the international competition to attract the best brain researchers.

In fact, people with lots of education are seven times more likely than high school dropouts to have no measurable disability a year later.<p>"It's a very dramatic difference," says <a href="https://www.hopkinsresearch.org/BIO/BIO_BioPg.aspx?User_ID=37446">Eric Schneider</a>, an epidemiologist at Johns Hopkins and the lead author of a new study.

The only exception to the helmet rule was for students who received an award.<p>"The big deal for them is that they can take the helmet off while they're walking across the stage," Soltesz says.

There was the time he fell "headfirst on a marble floor" and got a concussion, the day someone stole the family car ("my dad had to chase it down the block"), or the morning he found a black bat (the furry kind) in the house.<p>But Francis looks puzzled when his mom, Joanne Csedrik, asks him about a family trip to the Philippines when he was 3. "It was to celebrate someone's birthday," she tells him. "We took a long plane ride, two boat trips," she adds.
