Science Says: Unavoidable typos in DNA help fuel cancer

Cancer patients often wonder “why me?” Does their tumor run in the family? Did they try hard enough to avoid risks like smoking, too much sun or a bad diet? New research suggests random chance may play a bigger role than people realize.

Patterns in the Distribution of Lactase Persistence

This activity extends concepts covered in the film Got Lactase? The Co-Evolution of Genes and Culture. Students analyze data from the scientific literature to draw conclusions about the geographic distribution of lactase persistence.

Synchronized Division
