Why is the heart slightly on the left side of the body for most people? Why is DNA almost always a right-handed helix? Same with alpha helices, the building blocks of proteins. Chirality, or ...

After two years of failure, Griffith finally found an answer. Using a delicate technique that he describes as “more witchcraft than science,” he began spraying his DNA samples with a thin coating of ...

On a foggy Saturday morning in 1953, a tall, skinny 24-year-old man fiddled with shapes he had cut out of cardboard. They represented fragments of a DNA molecule, and young James Watson was trying to ...
