Shocking and controversial when it was first published in 1939, Steinbeck's Pulitzer prize-winning epic The Grapes of Wrath remains his undisputed masterpiece. Set against the background of Dust Bowl Oklahoma and Californian migrant life, it tells of Tom Joad and his family, who, like thousands of others, are forced to travel west in search of the promised land. Their story is one of false hopes, thwarted desires, and broken dreams, yet out of their suffering Steinbeck created a drama that is intensely human, yet majestic in its scale and moral vision.

With over 17,000 known diseases affecting humans, and countless poisons, carcinogens and toxins in our environment, it's a miracle that our bodies manage to keep us alive. And that is, of course, if they don't betray us themselves, whether through cancers or autoimmune conditions. Biomedical researcher Professor John Tregoning tells the unlikely story of how, against all odds, we manage to stay alive. Taking an organ-by-organ tour of the human body, Tregoning embarks on his own experimental quest, testing 'life-extending' diets and exercise regimes to separate fact from fad.

Paul Scharre, a Pentagon defense expert and former U.S. Army Ranger, explores what it would mean to give machines authority over the ultimate decision of life or death. Scharre's far-ranging investigation examines the emergence of autonomous weapons, the movement to ban them, and the legal and ethical issues surrounding their use. Through interviews with defense experts, ethicists, psychologists, and activists, Scharre surveys what challenges might face "centaur warfighters" on future battlefields.
