Known as Monsanto's Roundup by consumers, and as glyphosate by scientists, the world's most popular weed killer is used everywhere from backyard gardens to golf courses to millions of acres of farmland. For decades it's been touted as safe enough to drink, but a growing body of evidence indicates just the opposite, with research tying the chemical to cancers and a host of other health threats. In Whitewash, veteran journalist Carey Gillam uncovers one of the most controversial stories in the history of food and agriculture, exposing new evidence of corporate influence.

Chemistry is everywhere, and involves everything. But how did chemistry get to be what it is? I'm Steve Cohen, a chemist and writer, bringing you The History of Chemistry. This podcast explores the development of chemistry from prehistoric times to the present, including the people and societies who made chemistry what it is today. The History of Chemistry is for you, whether you hated chemistry in high school, or got a PhD in inorganic chemistry. We'll explore how chemistry affected art, music, language, politics and vice-versa. Whether it's ancient Greek philosophers, medieval alchemists, or...

'Forest bathing' or shinrin-yoku is a way of walking in the woods that was developed in Japan in the 1980s. It brings together ancient ways and wisdom with cutting-edge environmental health science. Simply put, forest bathing is the practice of walking slowly through the woods, in no hurry, for a morning, an afternoon or a day. It is a practice that involves all the senses and as you gently walk and breathe deeply, the essential oils of the trees are absorbed by your body and have an extraordinary effect on positive feelings.

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.

In both history and fiction, some of the most dramatic, notorious deaths have been through poisonings. Concealed and deliberate, it's a crime that requires advance planning and that for many centuries could go virtually undetected. And yet there is a fine line between healing and killing: The difference lies only in the dosage!

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

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?

From Beethoven's connection to plumbing to why rotten eggs smell like sulfur, the technical explanations included in this scientific primer tackle 99 chemistry-related questions and provide answers designed to inform and entertain. What jewelry metal is prohibited in some European countries? What does Miss Piggy have to do with the World Cup? How can a cockroach be removed from a human ear? The quirky information offered incorporates scientific savvy, practical advice, and amusing anecdotes.

In 2016, with the addition of four final elements - nihonium, moscovium, tennessine and oganesson - to make a total of 118 elements, the periodic table was finally complete, rendering any pre-existing books on the subject obsolete. Tim James, the secondary-school science teacher we all wish we'd had, provides an accessible and wonderfully entertaining 'biography of chemistry' that uses stories to explain the positions and patterns of elements in the periodic table.

Phosphorus has played a critical role in some of the most lethal substances on earth: firebombs, rat poison, nerve gas. But it’s also the key component of one of the most vital: fertilizer, which has sustained life for billions of people.

Written by award-winning science writer John Emsley, this informative and highly enjoyable book explains the what, the why and the wherefore of the elements. Arranged alphabetically, from Actinium to Zirconium, it is a complete guide to all the elements that are currently known, with more extensive coverage of those we encounter in our everyday life. The entry on each element reveals where it came from, what role it may have in the human body, the foods that contain it, how it was discovered, its role in human health, the uses and misuses to which it is put, and its environmental role.

If you have a chemistry exam tomorrow, thank goodness you're here. This book will help you memorize the entire periodic table in the fastest and easiest way possible. Would you like to remember the name of every single chemical element? And know their atomic numbers, too? If you've ever watched someone memorize a deck of playing cards in minutes, and dreamed about what you could do with a memory like that - your dreams are about to come true.

In Revelations in Air, Jude Stewart takes us on a fascinating journey into the weird and wonderful world of smell. Beginning with lessons on the incredible biology and history of how our noses work, Stewart teaches us how to use our noses like experts. Once we're properly equipped and ready to sniff, Stewart explores a range of smells - from lavender, cut grass, and hot chocolate to cannabis and old books - using smell as a lens into art, history, science, and more.

In The Alchemy of Us, scientist and science writer Ainissa Ramirez examines eight inventions - clocks, steel rails, copper communication cables, photographic film, light bulbs, hard disks, scientific labware, and silicon chips - and reveals how they shaped the human experience. Ramirez tells the stories of the woman who sold time, the inventor who inspired Edison, and the hotheaded undertaker whose invention pointed the way to the computer.

Eat this and live to 100. Don’t, and die. Today, hyperboles dominate the media, which makes parsing science from fiction an arduous task when deciding what to eat, what chemicals to avoid, and what’s best for the environment. In Is That a Fact?, best-selling author Dr. Joe Schwarcz carefully navigates the storm of misinformation to help us separate fact from folly and shrewdness from foolishness.

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.

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.

In an engaging tour of the science and history of cheese, Michael Tunick explores the art of cheese making, the science that lies underneath the deliciousness, and the history behind how humanity came up with one of its most varied and versatile of foods. Dr. Tunick spends his everyday deep within the halls of the science of cheese, as a researcher who creates new dairy products, primarily, cheeses.

Agatha Christie revelled in the use of poison to kill off unfortunate victims in her books; indeed, she employed it more than any other murder method, with the poison itself often being a central part of the novel. Her choice of deadly substances was far from random—the characteristics of each often provide vital clues to the discovery of the murderer. Christie's extensive chemical knowledge provides the backdrop for A Is for Arsenic, in which Kathryn Harkup investigates the poisons used by the murderer in fourteen classic Agatha Christie mysteries.
