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.

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.

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...

Our world is largely defined by what we see and hear-but our uses for light and sound go far beyond simply seeing a photo or hearing a song. A concentrated beam of light, lasers are powerful tools used in industry, research, and medicine, as well as in everyday electronics like DVD and CD players. Ultrasound, sound emitted at a high frequency, helps create images of a developing baby, cleans teeth, and much more. Light and Sound teaches how light and sound work, how they are used in our day-to-day lives, and how they can be used to learn about the universe at large.

Animals and plants use ingenious ways to reproduce and ensure the survival of their species. One of these methods is asexual reproduction, a process by which some plants and animals create clones. Scientists have adapted this process and invented techniques to generate clones for a variety of purposes. In Reproduction and Cloning, learn how researchers have studied a variety of reproductive processes to develop technology to treat infertility and produce new plants and animals, sometimes through controversial means.
