Bacteria are microscopic organisms with a cell structure that is very different from that of the other kingdoms. Traditionally classified according to their shape, scientists now use DNA studies to refine the groupings of bacteria. This book examines bacteria that are found in virtually every environmentincluding those that are characterized by extreme heat, cold, and depthand, of course, bacteria that are found inside our bodies. Intriguing information highlights the key role that bacteria play in shaping the ecology of our planet, how some bacteria make their own food while others feed on ready-made food, and how some do indeed cause disease, while most do not. Case studies examine the development of new vaccines against bacterial diseases and the use of bacteria to help fight pollution.

There are hundreds of thousands of different known fungi with many still to be discovered and developed. This interesting book features an examination of the four major groups: yeasts, toadstools, chytrids, and bread molds. Key characteristics of fungi are highlighted, such as spore production, fungis need to feed, and their use of long, branching cells known as hyphae to absorb nutrients from the environment. Special sections explore such varieties as saprophytes, which feed on dead and decaying matter; parasites, which often do considerable harm to other species; and species that form mutualistic relationships with other species to form composite organisms, such as lichen. Case histories involving fungi include penicillin and the fight against disease, and genetically modified (GM) products in food technology.

By the time Roberta Bondar became Canada's first woman in space in 1992, she already had careers as a doctor, a scientist, and a professional photographer. Born in 1945 in Sault Ste. Marie, Ontario, a town on the border between Canada and the United States, Roberta has had an active career in both countries. Today she is well known for her continuing work on behalf of the planet, writing and appearing on TV and in documentaries, covering Space Shuttle launches at the Kennedy Space Center in Florida, and shedding new light on the needs of the natural world.
