New research out of Washington University suggests the answer is "yes" to our headline question - that laws restricting how late at night teens can drive or how many passengers they can have may also be keeping teens from driving drunk.
The study used data from 1999 to 2009 on teen drinking and driving in 45 states with graduated driving licensing laws.
Wash U. psychologist Patricia Cavazos-Rehg led the study. She says states adopted teen driving restrictions at different times, and that some states are stricter than others.
A litter of three swift foxes, two females and one male, has been born at the Endangered Wolf Center in Eureka – the first in a dozen years. The four-week-old foxes will get their first round of vaccinations today.
The kits are being raised by a trio of adult foxes – the breeding female’s sister is helping the parents care for their young.
The associate director of Washington University in St. Louis' Genome Institute, George Weinstock, was one of this project's lead researchers. He says we have about ten times more microbial cells in our body than we have human cells.
He told our reporter Véronique LaCapra today:
“...there’s probably a hundred times or more microbial genes in our body than there are genes in our human genome,” Weinstock said. “So the microbes, they’re not just a small little part of us, they’re really a very, very large, perhaps almost dominant part of our body.”
The human body contains about 100 trillion cells, but only maybe one in 10 of those cells is actually human. The rest are from bacteria, viruses and other microorganisms. Now, scientists have unveiled the first survey the "human microbiome," which includes 10,000 species and more than 8 million genes.
Researchers have completed the first comprehensive census of the human “microbiome” — the trillions of bacteria, viruses, and other microorganisms that live in and on our bodies.

A rare astronomical event will take place Tuesday evening: The planet Venus will pass between Earth and the sun, appearing as a small black dot moving across the sun's bright disk. It's known as the transit of Venus, and it won't happen again for more than 100 years.
In the 1980s, the town of Times Beach, Mo. hired a contractor to spray the town’s dirt streets with oil to cut down on dust. That oil was later found to contain extremely high levels of dioxin, a known cause of cancer. Tests in the town revealed levels of dioxin 300 times what is considered safe by the Environmental Protection Agency.
An endangered beetle will be making its Missouri comeback on Tuesday.
That's when about 250 American burying beetles will be reintroduced in the Wah’Kon-Tah prairie, about 60 miles northwest of Springfield.
It's a joint effort of the Nature Conservancy, the U.S. Fish and Wildlife Service, the Missouri Department of Conservation, and the St. Louis Zoo.
It's been 40 years since a confirmed sighting of the insect in Missouri, and the director of the zoo’s Center for American Burying Beetle Conservation, Bob Merz, says he hopes it will get reestablished in the state.
