Radiation can be found everywhere since the universe began and Earth first formed. But what does 'radioactive' really mean? This title explains the science behind radiation, from the radiation in the body to the radiation in the environment; how radiation can create energy and cause destruction; and, how it saves lives every day.

The development of the plate tectonic theory was one of the great revolutions in the history of science. Before the plate tectonic theory, most scientists believed that Earth was a static planet that never really changed. Working like detectives, a small group of pioneering individuals slowly pieced together an entirely different picture of our Earth, showing that the planet is really a dynamic, active world. Over the course of millions of years, continents collided with each other, oceans opened and closed, and mountains rose and fell--and these changes continue today. "Plate Tectonics"...

From the tiniest microbe to the largest whale, all organisms have changed over vast expanses of time due to the forces of natural selection. This title presents an overview of the processes and causes that drive natural selection and the principles that explain how it operates, using numerous organisms as examples.

This title follows the pioneering obserations of Edwin Hubble and the early insights in cosmological theory by Alexander Friedmann and Father Georges Lemaitre. The discoveries of the cosmic microwave background and the expansion of the universe set the stage for new evidence about big bang origins.

Since humankind's earliest days, the rise of civilization led to a huge increase in the number and types of diseases that afflict the human population. Early prevailing theories about the causes of and cures for disease included superstitious beliefs, the application of herbal remedies, and the well-meant but ultimately misguided humoral theory of disease--a concept that persisted into the 19th century. Presenting a comprehensive history of the development of the germ theory of disease, Germ Theory profiles the major scientists who helped the theory, including Leeuwenhoek, Jenner, Pasteur,...

This title traces the history of the science of genetics from its birth in the studies of 19th century monk Gregor Mendel, through the discovery of the structure of DNA by Crick and Watson, to the future of genetic reasearch. It examines how research may find answers to genetic disorders and cures for heart disease and cancer.

Cell Theory traces the history of the development of the cell theory, which was first proposed almost 200 years ago, from the discovery of the cell through the investigations used to prove its accuracy. Today, scientists almost universally accept the cell theory. Readers will gain valuable knowledge about this scientific concept, helping them understand this life science topic.

Thousands of years ago, people fascinated by the motions of a few wandering 'stars'. Today, people know these objects are planets, but the quest to reach this understanding took thousands of years. This title helps to learn how scientists have found new planets outside the solar system, and continue their search for planets like Earth.

For billions of years, cells have used an ingenious system of storing and processing instructions to make proteins, the molecules that carry out vital functions for the cell. Data is warehoused in DNA molecules, copied into RNA molecules, and then read by a cell's protein synthesis apparatus. It is the genetic code that enables this data transfer to exist. The Genetic Code tracks the key experiments and discoveries that set in motion efforts to crack the code and explores the many ways humans have applied knowledge of the genetic code to alter gene activity. From the engineering of...
