How much of our daily caloric intake comes from ingesting substances that, technically speaking, do not meet traditional definitions of “food”? Chances are, if you’re eating something that came wrapped in plastic and contains a funky ingredient you don’t have in your kitchen, it's most likely—almost definitely—ultra-processed food, or UPF.

Emergency preparedness goes beyond stockpiling; it's about a comprehensive plan and skill development. If you've never prepped before, this guide provides a clear roadmap to make daunting tasks manageable.

It takes tremendous biological creativity to be a plant. To survive and thrive while rooted in a single spot, plants have adapted ingenious methods of survival. In recent years, scientists have learned about their ability to communicate, recognize their kin and behave socially, hear sounds, morph their bodies to blend into their surroundings, store useful memories that inform their life cycle, and trick animals into behaving to their benefit, to name just a few remarkable talents.

Shannon Vallor makes a wide-ranging, prophetic, and philosophical case for what AI could be: a way to reclaim our human potential for moral and intellectual growth, rather than lose ourselves in mirrors of the past. Rejecting prophecies of doom, she encourages us to pursue technology that helps us recover our sense of the possible, and with it the confidence and courage to repair a broken world. Vallor calls us to rethink what AI is and can be, and what we want to be with it.

One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

Where do we come from? How did our ancestors settle this planet? How did the great historic civilizations of the world develop? How does a past so shadowy that it has to be painstakingly reconstructed from fragmentary, largely unwritten records nonetheless make us who and what we are?

These 36 lectures bring you the answers that the latest scientific and archaeological research and theorizing suggest about human origins, how populations developed, and the ways in which civilizations spread throughout the globe.

This book is about pleasure. It’s also about pain. Most important, it’s about how to find the delicate balance between the two, and why now more than ever finding balance is essential. We’re living in a time of unprecedented access to high-reward, high-dopamine stimuli: drugs, food, news, gambling, shopping, gaming, texting, sexting, Facebooking, Instagramming, YouTubing, tweeting....

Here for the first time, in rich human, political, and scientific detail, is the complete story of how the bomb was developed, from the turn-of-the-century discovery of the vast energy locked inside the atom to the dropping of the first bombs on Japan. Few great discoveries have evolved so swiftly - or have been so misunderstood. From the theoretical discussions of nuclear energy to the bright glare of Trinity, there was a span of hardly more than 25 years.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.

Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate following. Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent of the speed of light? How fast can you hit a speed bump while driving and live? If there were a robot apocalypse, how long would humanity last?

Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; her TED talks have been viewed by more than 10 million people worldwide. In this, her first book, now available in audio, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths—that trees are not simply the source of timber or pulp, but are a complicated, interdependent circle of life.

In a time when our political and cultural views feel more polarized than ever, Tyson provides a much-needed antidote to so much of what divides us, while making a passionate case for the twin chariots of enlightenment—a cosmic perspective and the rationality of science. After thinking deeply about how science sees the world and about Earth as a planet, the human brain has the capacity to reset and recalibrates life’s priorities, shaping the actions we might take in response. No outlook on culture, society, or civilization remains untouched.

The science of emotion is in the midst of a revolution on par with the discovery of relativity in physics and natural selection in biology. Leading the charge is psychologist and neuroscientist Lisa Feldman Barrett, whose research overturns the long-standing belief that emotions are automatic, universal, and hardwired in different brain regions. Instead, Barrett shows, we construct each instance of emotion through a unique interplay of brain, body, and culture.

Sean Carroll is creating a profoundly new approach to sharing physics with a broad audience, one that goes beyond analogies to show how physicists really think. He cuts to the bare mathematical essence of our most profound theories, explaining every step in a uniquely accessible way. Quantum field theory is how modern physics describes nature at its most profound level. Starting with the basics of quantum mechanics itself, Sean Carroll explains measurement and entanglement before explaining how the world is really made of fields.

Something new entered our world in November 2022—the first general purpose AI that could pass for a human and do the kinds of creative, innovative work that only humans could do previously. Wharton professor Ethan Mollick immediately understood what ChatGPT meant: after millions of years on our own, humans had developed a kind of co-intelligence that could augment, or even replace, human thinking. Through his writing, speaking, and teaching, Mollick has become one of the most prominent and provocative explainers of AI.

In the wake of World War II, with America ascendant and the Soviet Union devastated by the conflict, the Space Race should have been over before it started. But the underdog Soviets scored a series of victories—starting with the 1957 launch of Sputnik and continuing in the years following--that seemed to achieve the impossible. It was proof, it seemed, that the USSR had manpower and collective will that went beyond America's material advantages. They had asserted themselves as a world power. But in The Wrong Stuff, John Strausbaugh tells a different story.
