includes booklets on cells, genes, health, chemistry, and medicines. The booklets explore advances in the development and delivery of drugs, links between genes and diseases, how genes work, the body's reaction to medicines, and the hundreds of thousands of molecules that perform specialized functions inside the fundamental unit of life (the cell). One booklet, "The Structures of Life," features stories designed to inspire young people to consider careers in biomedical research.

The human body keeps time with a master clock called the suprachiasmatic nucleus or SCN. Situated inside the brain, it's a tiny sliver of tissue about the size of a grain of rice, located behind the eyes. It sits quite close to the optic nerve, which controls vision, and this means that the SCN "clock" can keep track of day and night. Given enough time, your SCN can reset itself after you fly in an airplane from one time zone to another. |
