"Now it's off to the races," botanist Dave Erickson says of a project to barcode 250 species of plant life on Plummers Island.

Cracking the DNA Code

On a small island near Washington, D.C., Smithsonian researchers have found a genetic code that could revolutionize botany

Conventional wisdom held that only a huge stretch of DNA could function as a gene. The discovery of an overlooked genetic entity upends that view. Croce "was stunned."

Born with a disease that has robbed her eyesight, Alisha Bacoccini (being examined by surgeon Albert Maguire) is undergoing experimental gene therapy at the University of Pennsylvania. If she weren't legally blind, says the 20-year-old massage therapist, she would want to be a forensic scientist.

Gene Therapy in a New Light

A husband-and-wife team's experimental genetic treatment for blindness is renewing hopes for a controversial field of medicine

Jocelyn Kaiser graduated from Princeton University with a degree in chemical engineering. She now writes for Science magazine and is the author of Gene Therapy in a New Light, which appears in Smithsonian's January 2009 issue.

How Breast Cancer Genes Work

Though we may talk of cancer as one disease, skin cancer has little in common with pancreatic cancer and breast cancer is something else entirely

When it dives, the platypus closes its eyes, ears and nostrils and finds its food through electrical receptors in its bill that detect the movement of small prey.
