In high school, Matthew Smith busied himself designing websites, taking photos and making pottery. His younger brother, Tom, played trombone in the school jazz band, worked on his Eagle Scout badge and concentrated on honors classes in math, physics and geometry.

Like most teenagers preoccupied with their own pursuits, they didn't really notice anything unusual about their dad. But their friends did.

"They'd say, 'Your dad doesn't have any hair on his legs. Your dad's hair is really long'," said Matthew, 23.

Growing up with three brothers in a cramped house just outside Chicago, Michelle Smith delighted in the rare chance to slip into her mother's bra and black wig. As her heart pounded, her excitement was tempered only by the terror of being discovered. Had she been caught, Michelle feared her mother would not be amused by a 6-year-old's attempt to imitate mommy.

That's because Michelle was being raised as a son.

An international team of scientists has sequenced the genome of a duck-billed platypus. Part bird, part reptile and part mammal, the platypus genome sheds light on the evolution of mammals, including humans, and on the genetics of disease. Led by Richard K. Wilson, director of the Genome Sequencing Center at Washington University School of Medicine, the scientific team found that this mammal's DNA is as unusual as its duck-bill.
