Riveting and timely, a look at the research that is transforming our understanding of the cosmos in the quest to discover whether we are alone.

Something strange is going on in the cosmos. Scientists are uncovering a catalogue of weird phenomena that simply can’t be explained by our long-established theories of the universe. After decades of fruitless searching, could we finally be catching glimpses of a profound new view of our physical world? Or are we being fooled by cruel tricks of the data? In Space Oddities, Harry Cliff, a physicist who does cutting-edge work on the Large Hadron Collider, provides a riveting look at the universe’s most confounding puzzles.

In Bite, zoologist Bill Schutt makes a surprising case: it is teeth that are responsible for the long-term success of vertebrates. The appearance of teeth, roughly half a billion years ago, was an adaptation that allowed animals with backbones, such as fish, amphibians, reptiles, birds, dinosaurs and mammals—including us—to chow down in pretty much every conceivable environment.

On September 11, 1999, humanity made a monumental discovery in the vastness of space. Scientists uncovered an asteroid of immense scientific importance—a colossal celestial entity. As massive as an aircraft carrier and towering as high as the iconic Empire State Building, this cosmic titan was later named Bennu. Remarkable for much more than its size, Bennu belonged to a rare breed of asteroids capable of revealing the essence of life itself. But just as Bennu became a beacon of promise, researchers identified a grave danger.

In Waves in an Impossible Sea, physicist Matt Strassler tells a startling tale of elementary particles, human experience, and empty space. He begins with a simple mystery of motion. When we drive at highway speeds with the windows down, the wind beats against our faces. Yet our planet hurtles through the cosmos at 150 miles per second, and we feel nothing of it. How can our voyage be so tranquil when, as Einstein discovered, matter warps space, and space deflects matter? The answer, Strassler reveals, is that empty space is a sea, albeit a paradoxically strange one.

When he was six years old, Roger Penrose discovered a sundial in a clearing near his house. Through that machine made of light, shadow, and time, Roger glimpsed a “world behind the world” of transcendently beautiful geometry. It spurred him on a journey to become one of the world’s most influential mathematicians, philosophers, and physicists. Penrose would prove the limitations of general relativity, set a new agenda for theoretical physics, and astound colleagues and admirers with the elegance and beauty of his discoveries.

There are approximately 25,000 "city killer" asteroids in near-Earth orbit—and most are yet to be found. Small enough to evade detection, they are capable of large-scale destruction, and represent our greatest cosmic threat. But in September 2022, against all odds, NASA's Double Asteroid Redirection Test (DART) mission deliberately crashed a spacecraft into a carefully selected city killer, altering the asteroid's orbit. In How to Kill an Asteroid, award-winning science journalist Robin George Andrews reveals the development of the technology that made it possible

We’ve all heard the phrase “it’s not brain surgery.” But what exactly is brain surgery? It’s a profession that is barely a hundred years old and profoundly connects two human beings, but few know how it works, or its history. In this warm, rigorous, and deeply insightful book, Dr. Theodore H. Schwartz explores what it’s like to hold the scalpel, wield the drill, extract a tumor, fix a bullet hole, and remove a blood clot—when every second can mean life or death.

What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like. In Life as No One Knows It, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is.

In How the World Made the West, Josephine Quinn poses perhaps the most significant challenge ever to the “civilizational thinking” regarding the origins of Western culture—that is, the idea that civilizations arose separately and distinctly from one another. Rather, she locates the roots of the modern West in everything from the law codes of Babylon, Assyrian irrigation, and the Phoenician art of sail to Indian literature, Arabic scholarship, and the metalworking riders of the Steppe, to name just a few examples.

In the developed world, we’ve reaped the benefits of refrigeration for more than a century, but the costs are catching up with us. We’ve eroded our connection to our food and redefined what “fresh” means. More important, refrigeration is one of the leading contributors to climate change. As the developing world races to build a US-style cold chain, Twilley asks: Can we reduce our dependence on refrigeration? Should we?

The violent birth of the universe was only the first bang of a very bumpy ride. This unfathomably cacophonous beginning has spawned blasts, implosions, cosmic cannibalism, collisions, and countless other fleeting energetic events punctuating the cosmos. Although often brief, these transient phenomena pack a powerful punch. Astronomer and science writer C. Renee James introduces us to her colleagues around the world, who are using pioneering research techniques to explore everything from the very first explosions in the universe to the dark energy that could destroy it all.

Many of us know that the Moon pulls on our oceans, driving the tides, but did you know that it smells like gunpowder? Or that it was essential to the development of science and religion? Acclaimed journalist Rebecca Boyle takes listeners on a dazzling tour to reveal the intimate role that our 4.51-billion-year-old companion has played in our biological and cultural evolution.

During one sweltering week in July 1948, the Democratic Party gathered in Philadelphia for its national convention. The most pressing and controversial issue facing the delegates was not whom to nominate for president—the incumbent, Harry Truman, was the presumptive candidate—but whether the Democrats would finally embrace the cause of civil rights and embed it in their official platform. On the convention's final day, Hubert Humphrey, the relatively obscure mayor of the midsized city of Minneapolis, ascended the podium.

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.

We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat? Drawing on decades of research, Harvard psychiatrist Dr. Chris Palmer outlines a revolutionary new understanding that for the first time unites our existing knowledge about mental illness within a single framework: mental disorders are metabolic disorders of the brain. Brain Energy will transform the field of mental health, and the lives of countless people around the world.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

Hilarious, fascinating, and a roller coaster of dizzying, historical what-ifs, Napoleon's Hemorrhoids is a potpourri for serious historians and casual history buffs. In one of Phil Mason's many revelations, you'll learn that Communist jets were two minutes away from opening fire on American planes during the Cuban missile crisis, when they had to turn back as they were running out of fuel. You'll discover that before the Battle of Waterloo, Napoleon's painful hemorrhoids prevented him from mounting his horse to survey the battlefield.
