POPSDrug for Longer Life The other drug is a small synthetic chemical that is a thousand times as potent as resveratrol in activating sirtuin and can be given at a much smaller dose. Safety tests in people have just started, with no adverse effects so far. The hope is that activating sirtuins in people would, like a calorically restricted diet in mice, avert degenerative diseases of aging like diabetes, heart disease, cancer and Alzheimer’s. There is no Food and Drug Administration category for longevity drugs, so if the company is to submit a drug for approval, it needs to be for a specific disease. Nonetheless, longevity is what has motivated the researchers and what makes the drugs potentially so appealing.

POPSThe Role of Light on Human Health Rea envisions "real-time light prescriptions" to help people receive or avoid light at the appropriate times. Simple measures to control when and how much circadian light we receive could help nightshift workers stay alert on the job and sleep more effectively during the day, help cure jet lag, decrease depression, and generally help everyone get a proper night's sleep. The ability to modify circadian rhythm could potentially mitigate the negative health effects that some researchers believe are brought on by disruptions to the light-dark cycle. Recent studies have found a link between health and changes in the natural circadian rhythm. The Journal of the National Cancer Institute published a series of articles, for example, that showed night shift workers had a higher incidence of breast cancer; and, last year, the World Health Organization's International Agency for Research on Cancer cited night work as a potential breast cancer risk factor.

POPSWhen can empathy move us to action? And so cognitive empathy alone is not enough. We also need what Ekman calls "emotional empathy"—when you physically feel what other people feel, as though their emotions were contagious. This emotional contagion depends in large part on cells in the brain called mirror neurons, which fire when we sense another's emotional state, creating an echo of that state inside our own minds. Emotional empathy attunes us to another person's inner emotional world, a plus for a wide range of professions, from sales to nursing—not to mention for any parent or lover.
