The cell is the basic building block of life. In its 3.5 billion years on the planet, it has proven to be a powerhouse, spreading life first throughout the seas, then across land, developing the rich and complex diversity of life that populates the planet today. With The Cell: A Visual Tour of the Building Block of Life, Jack Challoner treats readers to a visually stunning tour of these remarkable molecular machines. Most of the living things we're familiar with--the plants in our gardens, the animals we eat--are composed of billions or trillions of cells. Most multicellular organisms consist of many different types of cells, each highly specialized to play a particular role--from building bones or producing the pigment in flower petals to fighting disease or sensing environmental cues. But the great majority of living things on our planet exist as single cell. These cellular singletons are every bit as successful and diverse as multicellular organisms, and our very existence relies on them. The book is an authoritative yet accessible account of what goes on inside every living cell--from building proteins and producing energy to making identical copies of themselves--and the importance of these chemical reactions both on the familiar everyday scale and on the global scale. Along the way, Challoner sheds light on many of the most intriguing questions guiding current scientific research: What special properties make stem cells so promising in the treatment of injury and disease? How and when did single-celled organisms first come together to form multicellular ones? And how might scientists soon be prepared to build on the basic principles of cell biology to build similar living cells from scratch.

A lively introduction to rocks and minerals and how they are formed and used, with facts, pictures and science projects to try yourself, perfect for 8-12 year-olds at home or school.

An accessible and engaging guide to the atom, the smallest, most fundamental constituent of matter.Until now, popular science has relegated the atom to a supporting role in defining the different chemical elements of the periodic table. In this book, Jack Challoner places the atom at center stage. The Atom investigates the quest to identify the smallest, most fundamental constituents of matter--and how that quest helps us to understand what everything is made of and how it all works. Challoner covers a wide range of topics--including the development of scientific thinking about atoms and the basic structure of atoms; how atomic interactions account for the familiar properties of everyday materials; the power of the atomic nucleus; and what the mysterious quantum realm of subatomic particles can tell us about the very nature of reality. Illustrated in color throughout, The Atom offers clear answers to questions we have all pondered, as well as some we have never even dreamed of. It describes the amazing discoveries scientists have made about the fundamental building blocks of matter--from quarks to nuclear fission to the "God particle"--and explains them accessibly and concisely. The Atom is the engaging and straightforward introduction to the topic that we didn't get in school.

Everything in the universe is made up of the elements - including us. Forged in the Big Bang, the elements and their resulting compounds created the solar system, planet Earth, the air we breathe, the water we rely on and the proteins that would become life. In fact, everything in the known Universe is made up of one of the 118 elements of the periodic table - so we really should know something about them! This little book is the perfect guide, listing all the elements' vital stats, and exploring their astonishing histories and usages in an accessible and easy-to-understand way.

John Snow was a Victorian physician who helped to establish that cholera was spread by contaminated water (not bad air, as theory had it). He traced the source of a deadly cholera outbreak to one pump and was able to have it closed, ending the outbreak, despite deep resistance from the local authorities, who did not want to believe his theory. This was a massive event in public health and the founding event of the science of epidemiology. Snow was also an early pioneer of anaesthesia. A dedicated scientist, the results of his work are still evident. He saved untold lives. This is his story.
