In her international bestseller SPQR, Mary Beard told the thousand-year story of ancient Rome. Now she shines her spotlight on the emperors who ruled the Roman empire, from Julius Caesar (assassinated 44 BCE) to Alexander Severus (assassinated 235 CE). Emperor of Rome is not your usual chronological account of Roman rulers, one after another: the mad Caligula, the monster Nero, the philosopher Marcus Aurelius.

Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do.

Argentine poet Jorge Luis Borges was madly in love when his life was shattered by painful heartbreak. But the breakdown that followed illuminated an incontrovertible truth—that love is necessarily imbued with loss, that the one doesn’t exist without the other. German physicist Werner Heisenberg was fighting with the scientific establishment on the meaning of the quantum realm’s absurdity when he had his own epiphany—that there is no such thing as a complete, perfect description of reality.

At a time when the very foundations of American democracy seem under threat, the lessons of the past offer a road map for navigating a moment of political crisis. In Democracy Awakening, acclaimed historian Heather Cox Richardson delves into the tumultuous journey of American democracy, tracing the roots of Donald Trump’s “authoritarian experiment” to the earliest days of the republic.

Some of engineering's mightiest achievements are small in scale, even hidden—and yet, without them, the complex machinery on which our modern world runs would not exist. In Nuts and Bolts, Roma Agrawal examines seven of these extraordinary elements: the nail, the wheel, the spring, the lens, the magnet, the string, and the pump. From the physics behind both Roman nails and modern skyscrapers to rudimentary springs that inspired lithium batteries, Agrawal shows us how even the most sophisticated items are built on the foundations of these ancient and fundamental breakthroughs in engineering.

Some 40 million miles of roadways encircle the earth, yet we tend to regard them only as infrastructure for human convenience. While roads are so ubiquitous they're practically invisible to us, wild animals experience them as entirely alien forces of death and disruption. In Crossings, environmental journalist Ben Goldfarb travels throughout the United States and around the world to investigate how roads have transformed our planet. A million animals are killed by cars each day in the US alone, but as the new science of road ecology shows, the harms of highways extend far beyond roadkill.

Homer’s Iliad and Odyssey are unquestionably two of the greatest epic masterpieces in Western literature. Though more than 2,700 years old, their stories of brave heroics, capricious gods, and towering human emotions are vividly timeless. The Iliad can justly be called the world’s greatest war epic. The terrible and long-drawn-out siege of Troy remains one of the classic campaigns. The Odyssey chronicles the many trials and adventures Odysseus must pass through on his long journey home from the Trojan wars to his beloved wife.

In the 1950s, an obsessive firearms designer named Eugene Stoner invented the AR-15 rifle in a California garage. High-minded and patriotic, Stoner sought to devise a lightweight, easy-to-use weapon that could replace the M1s touted by soldiers in World War II. What he did create was a lethal handheld icon of the American century.

In the weeks after Japan finally surrendered to the Allies to end World War II, the world turned to the question of how to move on from years of carnage and destruction. For Harry Truman, Douglas MacArthur, Chiang Kai-shek, and their fellow victors, the question of justice seemed clear: Japan’s militaristic leaders needed to be tried and punished for the surprise attack at Pearl Harbor.

Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.

It was supposed to be a moment of great optimism, a cause for jubilation. The Congo was at last being set free from Belgium—one of seventeen countries to gain independence in 1960 from ruling European powers. At the helm as prime minister was charismatic nationalist Patrice Lumumba. Just days after the handover, however, the Congo’s new army mutinied, Belgian forces intervened, and Lumumba turned to the United Nations for help in saving his newborn nation from what the press was already calling “the Congo crisis.”

We are approaching a critical threshold in the history of our species. Everything is about to change. Soon you will live surrounded by AIs. They will organize your life, operate your business, and run core government services. You will live in a world of DNA printers and quantum computers, engineered pathogens and autonomous weapons, robot assistants and abundant energy.

Benjamín Labatut’s When We Cease to Understand the World electrified a global readership. A Booker Prize and National Book Award finalist, and one of the New York Times’ Ten Best Books of the Year, it explored the life and thought of a clutch of mathematicians and physicists who took science to strange and sometimes dangerous new realms. In The MANIAC, Labatut has created a tour de force on an even grander scale.

What if you woke up one morning and found you’d acquired another self—a double who was almost you and yet not you at all? What if that double shared many of your preoccupations but, in a twisted, upside-down way, furthered the very causes you’d devoted your life to fighting against? Not long ago, the celebrated activist and public intellectual Naomi Klein had just such an experience—she was confronted with a doppelganger whose views she found abhorrent but whose name and public persona were sufficiently similar to her own that many people got confused about who was who.

Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole’s core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. In White Holes, he reveals the mind of a scientist at work.
