Tells what happened on August 5, 1949 in Man Gulch, Montana when fifteen smokejumpers came to fight a forest fire.

On August 5, 1949, a crew of fifteen Smokejumpers, the United States Forest Service''s elite airborne firefighters, stepped into the sky above a remote forest fire in the Montana wilderness. Less than two hours after their jump, all but three of these men were dead or fatally burned. Exactly what happened in Mann Gulch that day has been obscured by years of grief and controversy. Now a master storyteller finally gives the Mann Gulch fire its due as tragedy. Norman Maclean first saw the Mann Gulch fire as it still burned in mid-August 1949, and even then he knew he would one day become a part of its story. Maclean spent the last fourteen years of his life studying and reliving the fire. Young Men and Fire is the long-awaited result, a story of Montana, of the ways of wildfires, firefighters, and fire scientists, and especially of a crew, young and proud, who "hadn''t learned to count the odds and to sense they might owe the universe a tragedy." This tale is also Maclean''s own, the story of a writer obsessed by a strange and human horror, unable to let the truth die with these young men, searching for the last - and lasting - word. Nature''s violence collides with human fallibility in Young Men and Fire. The Smokejumpers in Mann Gulch are trapped by a "blowup," a deadly explosion of flame and wind rarely encountered and little understood at the time. Only seconds ahead of the approaching firestorm, the foreman, R. Wagner Dodge, throws himself into the ashes of an "escape fire "--And survives as his confused men run, their last moments obscured by smoke. The parents of the dead cry murder, charging that the foreman''s fire killed their boys. Years later, Maclean returns to the scene with two of the survivors and pursues the mysteries that Mann Gulch has kept hidden since 1949. From the words of witnesses, the evidence of history, and the research of fire scientists, Maclean at last assembles the scattered pieces of the Mann Gulch tragedy.

First published in 1987, this book is about how cells differentiate; that is it describes the way in which cells in animal and plant bodies take on their specialised fates. It has long been recognised that since all such cells retain copies of all genes, the genetic explanation for tissue differences lies in the controlled expression of restricted sets of genes. But how is the choice made and how are such restricted groups of genes activated and regulated? This book discusses these questions and describes both determination and differentiation. The mechanisms that underlie the processes are described for the embryo and in the adult. Determination may occur in adult life during regeneration, wound healing, cancer formation and in the immune and blood systems, and the possible genetic basis for the events is explored. The influence of the cell environment, the cell surface and the pericellular-extracellular matrix as mediators of external signals is discussed.
