Once every three months, Peter Raven pays a visit to his dermatologist. Summers spent at 10,000 feet, hiking northern California's Sierra Nevada Mountains and roaming the sand dunes and vacant lots of San Francisco take their toll. "That did a real number on my skin. Of course, nobody thought a thing about the sun in the 1950s," Raven said, describing a boyhood spent outdoors, rearing butterflies, collecting insects and gathering plants.  

This article first appeared in the St. Louis Beacon: November 18, 2008 - In the world of cancer research, the patient is the unsung hero. Without patients and families willing to take part, much of genetic research into the origins of cancer would not be possible. With this partnership, scientists at Washington University in St. Louis are the first to sequence the complete genome of a tumor and compare it, side-by-side, with the genome of healthy cells from the same person. It is, they hope, a step toward personalized cancer treatment.

This article first appeared in the St. Louis Beacon: November 18, 2008 - Quantum mechanics, evolution, brain surgery, genetics, economics, extra-terrestrial life -- these weighty topics were just a few of those discussed recently at the St. Louis Science Center's "Evening with Inspiring Scientists."

To showcase the importance of science and encourage a dialogue between scientists and the public, the Science Center assembled a panel of "star" scientists and science communicators, including astrophysicist Neil deGrasse Tyson, host of NOVA scienceNOW on PBS and director of the Hayden Planetarium at the American Museum of Natural History.

This article first appeared in the St. Louis Beacon: September 12, 2008 - Richard Sayre always wanted to be a scientist.

"I was a nerdy little kid," he says laughing and recalling an early foray into renewable energy production. In high school, he and his father built a device they hoped would generate an electrical current when heated, almost like a solar-powered battery. For the first test run, they put it in an oven, rigged up a way to measure current, and flipped the switch.

This article first appeared in the St. Louis Beacon: 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.

This article first appeared in the St. Louis Beacon: Twenty million Americans celebrated the first Earth Day on April 22, 1970. That massive outpouring of activism forced politicians to pay attention to the environment and resulted in the founding of the Environmental Protection Agency and the passing or strengthening of laws regulating clean air, clean water and endangered species. In just a few years, this grassroots, democratic action made the United States a world leader in environmental protection.
