Making grapefruit juice safer for people who take certain prescription drugs Intro theme and music by Kevin MacLeod (incompetech.com)

Life expectancy in the 20th Century rose by about 30 years. Advances in protecting the public health were responsible for about 25 of those precious years. Vaccination programs. Improved sanitation to better control infectious diseases. The development of antibiotics. Better prenatal care. And much more. Scientists are making strides toward sustaining that progress by fostering continued improvements in the health of the population as a whole.

Blueberries, raspberries and grapes bursting with flavor. A luscious, silky morsel of chocolate melting into a mouthful’s rush of pure pleasure. Fresh ripe tomatoes. Years ago, people ate for that gratification. Food also provided the calories for people to work, and drove away hunger pangs. Today, people in industrialized countries are selecting food not just for taste and sustenance, but also for its potential effects in promoting good health.

Every Thanksgiving, family and friends gather to celebrate round dinner tables heaped high with roast turkey and other traditional dishes. There’s praise and thanks for the food, of course. But maybe we should add a word of thanksgiving for the scientific advances that are helping to keep our food supply safe from a host of threats that can really spoil a meal.

Join Global Challenges as it investigates a suite of new fuels and energy sources that may help to power society in the years ahead. Scientists are developing these new energy sources to supplement the coal and conventional natural gas we now use to produce electricity for heating, cooling, and lighting. New fuels hold special promise as sustainable energy sources that minimize the release of carbon dioxide and combat global warming.

Amid growing concern about high gasoline prices, global warming, and limited resources of petroleum, scientists and engineers around the world are on a quest for new fuels — alternatives to conventional petroleum, natural gas, and coal. On their radar screens are new sources of familiar old ethanol that do not strain the food supply and futuristic fuels like “green gasoline” and “designer” hydrocarbons.

Despite the revolutionary medical advances in the 20th Century, great challenges lie ahead in our fight against disease. Heart disease, cancer, chronic diseases of aging, infection with the AIDS virus, and antibiotic-resistant microbes are just a few of those challenges. Fortunately, chemists and other scientists are determined to launch new revolutions in medicine — revolutions in the prevention, early diagnosis, and treatment of disease.
