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.

Optimism and hurricanes are not words we usually utter together, but the Atlantic hurricane season begins June 1st, and today government forecasters offered some cautious optimism. They are expecting a relatively quiet year.

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.

"It was to celebrate someone's birthday," she tells him. "We took a long plane ride, two boat trips," she adds.
