Here's a biographical profile of Charles Goodyear, the man who gave the world one of its most useful products - vulcanized rubber. Natural rubber, the milky sap of rubber trees, is not a very practical commodity. It melts in hot weather or cracks and freezes in cold weather. In 1839, Charles Goodyear came across a process that made rubber so useful it changed the world we live in. A century later there were 122 rubber factories in Ohio.

What can beer teach us about biology, history, and the natural world? From ancient Mesopotamian fermentation practices to the resurgent American craft brewery, authors Rob DeSalle and Ian Tattersall peruse the historical record and traverse the globe for engaging and often surprising stories about beer. They explain how we came to drink beer, what ingredients combine to give beers their distinctive flavors, how beer's chemistry works at the molecular level, and how various societies have regulated the production and consumption of beer.

We all know that without water we couldn't survive, and that sometimes a cup of coffee or a glass of wine feels just as vital. But do we really understand how much we rely on liquids, or the destructive power they hold? Set over the course of a flight from London to San Francisco, Liquid Rules offers listeners a fascinating tour of these formless substances, told through the language of molecules, droplets, heartbeats, and ocean waves.

The Element in the Room will take you on a rib-tickling, experiment-fuelled adventure to explain everyday science that is staring you in the face. If you are sci-curious, pi-curious or just the-end-is-nigh-curious then this is the book for you. Steve Mould and Helen Arney are two thirds of science comedy phenomenon Festival of the Spoken Nerd.

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.

The internet is a powerful beast when it comes to science; the answer to any query you may have is just a few keystrokes away. Dr. Joe takes a critical look at how facts are misconstrued in the media. He debunks the myths surrounding canned food, artificial dyes, SPF, homeopathy, cancer, chemicals, and more.

The complex ecosystem of the Amazon covers an area about the size of the continental US. Approximately one of every four flowering plant species on earth resides in the Amazon. A single Amazonian river may contain more fish species than all the rivers in Europe combined. The rain forest, which contains approximately 390 billion trees, plays a vital role in stabilizing the global climate by absorbing massive amounts of carbon dioxide - or releasing it into the atmosphere if the trees are destroyed.

The iconic periodic table of the elements is now in its most satisfyingly elegant form. This is because all the "gaps" corresponding to missing elements in the seventh row, or period, have recently been filled and the elements named. But where do these names come from? For some, usually the most recent, the origins are quite obvious, but in others - even well-known elements such as oxygen or nitrogen - the roots are less clear. Here, Peter Wothers explores the fascinating and often surprising stories behind how the chemical elements received their names.

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).

Author David Deamer addresses questions that are the cutting edge of research on the origin of life. In Assembling Life, he provides an overview of conditions on the early Earth four billion years ago and explains why freshwater hot springs are a plausible alternative to salty seawater as a site where life can begin.

Science and technology are, without a doubt, two forces that will change the way you live your life in the coming months, years, and decades. And in recent decades, these forces have evolved and developed at a lightning-fast pace. Explore the many possibilities of what your future may look like with these 24 lectures: a scientifically accurate and enlightening survey of today's most advanced research in fields such as engineering, biology, chemistry, and theoretical physics.

What do bubbles in a soft drink, a bullet-proof vest, a plastic chair, and our DNA have in common? Carbon. It is, and forever has been, the ubiquitous architect of life and civilization, forming the chemical backbone of every living creature. And yet, when we hear the word today, it is more often than not in a crisis situation: carbon dioxide emissions are destroying the ozone layer and warming the planet; the volatile Middle East explodes atop its stores of hydrocarbons; carbohydrates threaten obesity and diabetics.

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.

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.

This audiobook explains the scientific tools and techniques that revealed the century's biggest food fraud scams. It looks in detail at the biggest scams in recent times; drawing on the lead author's extensive experience at the forefront of the fight against these fraudsters, it goes on to explore the arms race between scientists and adulterers as better techniques for detection spur more creative and sophisticated means of adulteration.

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.

We all know that we depend on elements for survival - from oxygen in the air we breathe to carbon in the molecular structures of all living things. But we seldom appreciate how, say, phosphorus holds our DNA together or how potassium powers our optic nerves enabling us to see.

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.

A series of glasses of transparent liquids is in front of you: but which will quench your thirst and which will kill you? And why? Why does one liquid make us drunk and another power a jumbo jet? Sometimes dangerous, often delightful and always fascinating, discover the secret lives of liquids, from one of our best known scientists. From the best-selling author of Stuff Matters comes a fascinating tour of the world of these surprising or sinister substances - the droplets, heartbeats and ocean waves we encounter day to day.
