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.

Genius Inventions gives readers an unprecedented insight into the events, people and histories behind technological and scientific developments that have helped shape modern civilization. Discover the inspiration for some of the most important moments in the history of technology. An invention is rarely the brainchild of a single person, however brilliant, and the book includes timelines that explain the development of each creation and pays homage to some of the other great developments that came before and after. Beautifully illustrated throughout, showing 20 items of rare, on-the-page documents and memorabilia. See plans of the Wright Brothers' plane and extracts from the notebook of Alexander Graham Bell.

The Compact Guide: The Elements is authoritative and accessible, with a sense of wonder about the way in which the material world works, thanks to the protons, neutrons and electrons that make up the atoms of the elements. Everything in the known Universe is made up of one of the 118 elements of the periodic table, and this is your definitive guide. Every element is featured, their vital statistics given, their main compounds and uses explored, and their fascinating histories told. Forged in the Big Bang, the elements and their resulting compounds created our Solar System, the planet we live on, the air we breathe, the water we rely on, and the proteins that would become life. What links the Taj Mahal and our skeleton? Calcium. The Eiffel Tower and our blood? Iron. The salt on our chips and the street lamps that guide us home? Sodium. The elements make up everything, and this book is the perfect guide to every one of them.

The power of images to represent the unseeable: stunning visualizations of science, from the microscopic to the incredibly vast. We live among patterns of delicate beauty and exquisite chaos that our eyes can't detect; we are surrounded by invisible particles and shifting fields of matter that permeate all of space. Our very cells are intricate molecular machines, and the story of our origins stretches back through an unimaginable amount of time. How can we see the richness of what lies beyond our sensory perception? Scientists have developed visualization tools that can make the invisible visible. This bountifully illustrated book demonstrates the power of images to represent the unseeable, offering stunning visualizations of science that range from the microscopic to the incredibly vast. With more than 200 color images and an engaging text by leading science writer Jack Challoner, Seeing Science explains and illustrates the techniques by which scientists create visualizations of their discoveries. We see the first detection of a black hole as represented by an image from an Xray telescope, get a direct view of DNA through an electron microscope, and much more. Visualizations are also used to make sense of an avalanche of data--concisely presenting information from the 20,000 or so human genes, for example. Scientists represent complex theories in computer models, which take on a curious beauty of their own. And scientists and artists collaborate to create art from science visualizations, with intriguing results.

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.
