Scratch beneath the surface of a coffee bean, a red pepper flake, a poppy seed, a mold spore, a foxglove leaf, a magic-mushroom cap, a marijuana bud, or an apple seed, and we find a bevy of strange chemicals. We use these to greet our days (caffeine), titillate our tongues (capsaicin), recover from surgery (opioids), cure infections (penicillin), mend our hearts (digoxin), bend our minds (psilocybin), calm our nerves (CBD), and even kill our enemies (cyanide). But why do plants and fungi produce such chemicals? And how did we come to use and abuse some of them?

NASA Astrobiologist and renowned scientist Dr. David Grinspoon brings listeners an optimistic message about humanity's future in the face of climate change. For the first time in Earth's history, our planet is experiencing a confluence of rapidly accelerating changes prompted by one species: Humans. Climate change is only the most visible of the modifications we've made - up until this point, inadvertently - to the planet. And our current behavior threatens not only our own future but that of countless other creatures.

In The Elements We Live By, physicist and award-winning author Anja Røyne takes us on an astonishing journey through chemistry and physics, introducing the building blocks from which we humans - and the world - are made. Not only does Røyne explain why our bodies need iron, phosphorus, silicon, potassium, and many more elements in just the right amounts in order to function, she also leads us around the world to where these precious elements are found (some of them in ever-shrinking quantities).

No journalist has ever been allowed into the ultrasecretive, highly pressured process of originating a perfume. But Chandler Burr, the New York Times perfume critic, spent a year behind the scenes observing the creation of two major fragrances.

The audio is focused and high-yield, covering the most important topics you might expect to learn in a typical undergraduate chemistry course. The material is accurate, up-to-date, and broken down into bite-sized chapters. There are quizzes and key takeaways following each chapter to review questions commonly tested and drive home key points.

For decades, biology has been dominated by the study of genetic information. Information is important, but it is only part of what makes us alive. Our inheritance also includes our living metabolic network, a flame passed from generation to generation, right back to the origin of life. In Transformer, biochemist Nick Lane reveals a scientific renaissance that is hiding in plain sight-how the same simple chemistry gives rise to life and causes our demise.

Alexander (better known as “Sasha”) and Ann Shulgin’s PiHKAL: A Chemical Love Story has become a foundational work in the genre and was the first book to fully impart the how-to chemistry, and convey the effects, of many of the entheogenic drugs that are currently being studied and used to heal trauma and deal with death.

Long Hard Road provides an inside look at the birth of the lithium-ion battery, from its origins in academic labs around the world to its transition to its new role as the future of automotive power. It chronicles the piece-by-piece development of the battery, from its early years when it was met by indifference from industry to its later emergence in Japan where it served in camcorders, laptops, and cell phones. The book is the first to provide a glimpse inside the Japanese corporate culture that turned the lithium-ion chemistry into a commercial product.

Chemistry for Breakfast is a perfect book for anyone who wants to deepen their understanding of chemistry without having prior knowledge of the science. With Mai as your guide, you'll find something fascinating everywhere around you.

In The Secrets of Alchemy, Lawrence M. Principe, one of the world's leading authorities on the subject, brings alchemy out of the shadows and restores it to its important place in human history and culture. By surveying what alchemy was and how it began, developed, and overlapped with a range of ideas and pursuits, Principe illuminates the practice. He vividly depicts the place of alchemy during its heyday in early modern Europe, and then explores how alchemy has fit into wider views of the cosmos and humanity.

In Proof, Adam Rogers reveals alcohol as a miracle of science, going deep into the pleasures of making and drinking booze—and the effects of the latter. The people who make and sell alcohol may talk about history and tradition, but alcohol production is really powered by physics, molecular biology, organic chemistry, and a bit of metallurgy—and our taste for those products is a melding of psychology and neurobiology.

Among Americans, diabetes is more prevalent today than ever. Obesity is at epidemic proportions; nearly 10% of children are thought to have nonalcoholic fatty liver disease. And sugar is at the root of these, and other, critical, society-wide, health-related problems. With his signature command of both science and straight talk, Gary Taubes delves into Americans' history with sugar: its uses as a preservative, as an additive in cigarettes, the contemporary overuse of high-fructose corn syrup.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?

For centuries, scientists believed that living matter possessed a special quality—a spirit or essence—that differentiated it from nonliving matter. But by the nineteenth century, the scientific consensus was that the building blocks of one were identical to the building blocks of the other. Elixir tells the story of two young chemists who were not convinced, and how their work rewrote the boundary between life and nonlife.

Written in plain English, The Chemistry Book is packed with short, pithy explanations of some of the most historic moments in science, from the birth of atomic theory to the discovery of polythene and the development of new vaccine technologies to combat COVID-19.

Cheese puffs. Coffee. Sunscreen. Vapes. George Zaidan reveals what will kill you, what won’t, and why - explained with high-octane hilarity, hysterical hijinks, and other things that don’t begin with the letter H. Ingredients offers the perspective of a chemist on the stuff we eat, drink, inhale, and smear on ourselves. Apart from the burning question of whether you should eat that Cheeto, Zaidan explores a range of topics.

Have you ever wondered what makes dough rise? Or how your morning coffee gives you that energy boost? Or why your shampoo is making your hair look greasy? The answer is chemistry. From the moment we wake up until the time we go to sleep (and even while we sleep), chemistry is at work - and it doesn't take a PhD in science to understand it.

In this podcast, Taylor and Andrew investigate the past, present, and future of materials science and engineering. Topic areas ranging from cutting edge materials technology, the history of different materials, the commercialization of new materials, and exciting advances in processing and characterization are all covered in detail. Our episodes include things like the unlikely discovery of superglue or teflon, the fascinating backstories about modern biomaterials like dialysis filters, and updates on new technologies including wearable electronics, next generation batteries, and nanomaterials...

Of all the dietary and nutritional claims pitched to us, what can we believe? How does cinnamon affect your health? How splendid is Splenda? Should you buy farmed, wild, or canned food? What's fishy about fish-oil supplements? Will a diet of Twinkies and M&M's lead to weight loss? Water from a tap or from a plastic bottle - which should you choose, and which is better for the environment? Should you carry your groceries home in plastic or brown paper? We all have questions, and Dr. Joe Schwarcz has the answers, some of which will astonish you.

Interesting anecdotes and engaging tales make science fun, meaningful, and accessible. Separating sense from nonsense and fact from myth, these essays cover everything from the ups of helium to the downs of drain cleaners and provide answers to numerous mysteries, such as why bug juice is used to color ice cream and how spies used secret inks. Mercury in teeth, arsenic in water, lead in the environment, and aspartame in food are discussed.
