Vitamin C begins with scurvy, which afflicted Europe for four hundred years and killed millions. The reasons that a disease whose cure was known from the outset persisted over that time are at once baffling and familiar, and these trials eventually lead to invention of the science of epidemiology. Author Stephen M. Sagar MD then chronicles the discovery of vitamins at the beginning of the twentieth century, a story that encapsulates the rise of a scientific approach to nutrition but with surprising twists and turns.

In Regenesis, George Church and science writer Ed Regis explore the possibilities of the emerging field of synthetic biology. Synthetic biology, in which living organisms are selectively altered by modifying substantial portions of their genomes, allows for the creation of entirely new species of organisms. These technologies - far from the out-of-control nightmare depicted in science fiction - have the power to improve human and animal health, increase our intelligence, enhance our memory, and even extend our life span.

The man known as Jack Parsons, a maverick rocketeer who helped transform a derided sci-fi plotline into actuality, was at first mourned as a scientific prodigy. But reporters soon uncovered a more shocking story: Parsons had been a devotee of the city’s occult scene.

At a time when many people around the world are living into their 10th decade, the longest longitudinal study of human development ever undertaken offers some welcome news for the new old age: Our lives continue to evolve in our later years and often become more fulfilling than before. Begun in 1938, the Grant Study of Adult Development charted the physical and emotional health of over 200 men, starting with their undergraduate days.

Each one of us has roughly nine pints of it, yet many don’t even know their own blood type. And for all its ubiquitousness, the few tablespoons of blood discharged by 800 million women are still regarded as taboo: menstruation is perhaps the single most demonized biological event.
