This unique book looks at the biology of aging from a fundamentally new perspective, one based on evolutionary theory rather than traditional concepts which emphasize molecular and cellular processes. The basis for this approach lies in the fact that natural selection, as a powerful determining force, tends to decline in importance with age. Many of the characteristics we associate with aging, the author argues, are more the result of this decline than any mechanical imperative contained within organic structures. This theory in turn yields the most fruitful avenues for seeking answers to the problem of aging, and should be recognized as the intellectual core of gerontology and the foundation for future research. The author ably surveys the vast literature on aging, presenting mathematical, experimental, and comparative findings to illustrate and support the central thesis. The result is the first complete synthesis of this vital field. Evolutionary biologists, gerontologists, and all those concerned with the science of aging will find it a stimulating, strongly argued account.
Would Hitler have won the war had he not "given" the Allies Germany's most talented scientists? This is the gripping & sobering story of some of the greatest scientists of our times who, forced to flee Nazism, sought refuge in Great Britain & the United States.

Is there a `right way' to study coordination? What experimental paradigms are appropriate? Are there laws and principles that the biological system uses to coordinate movement? Do all biological systems - human and otherwise - share these same principles? Is coordination inherited or acquired? Is it a central nervous system, muscular, or mechanical problem? Indeed, what is coordination and how can it be quantified?This volume attempts to help to answer some of these questions by bringing together a collection of conceptual approaches to and empirical investigations of the coordination of movement. The authors of the chapters are well known and respected researchers from a variety of discipli...

René Théophile Hyacinthe Laennec (1781-1826) is best known for his invention of the stethoscope, one of medicine's most powerful symbols. Histories, novels, and films have cloaked his life in hagiography and legend. Jacalyn Duffin's fascinating new biography relies on a vastly expanded foundation of primary source material, including thousands of pages of handwritten patient records, lecture notes, unpublished essays, and letters. She situates Laennec, the scientist and teacher, within the broader social and intellectual currents of post-Revolutionary France. Her work uncovers a complex character who participated actively in the dramatic changes of his time. Laennec's famous Treatise on Me...
Argues that death is not unchanging, but rather has evolved over time.
“If you want to understand evolution, you need to understand the murky world of epigenetics. A hearty congratulations should be paid to Hallgrimsson and Hall, who provide reliable and steady illumination.”-Bernard Wood, Center for the Advanced Study of Hominid Paleobiology, George Washington University
Classical physics states that physical reality is local--a point in space cannot influence another point beyond a relatively short distance. However, In 1997, experiments were conducted in which light particles (photons) originated under certain conditions and traveled in opposite directions to detectors located about seven miles apart. The amazing results indicated that the photons "interacted" or "communicated" with one another instantly or "in no time." Since a distance of seven miles is quite vast in quantum physics, this led physicists to an extraordinary conclusion--even if experiments could somehow be conducted in which the distance between the detectors was half-way across the known ...
It may be the deepest mystery of philosophy, psychology, and neuroscience: how does the brain unite to create the self, the subjective "I"? In Altered Egos, Dr. Todd Feinberg presents a new theory of the self, based on his first-hand experience as both a psychiatrist and neurologist. Feinberg first introduces the reader to dozens of intriguing cases of patients whose disorders have resulted in what he calls "altered egos": a change in the brain that transforms the boundaries of the self. He describes patients who suffer from "alien hand syndrome" where one hand might attack the patient's own throat, patients with frontal lobe damage who invent fantastic stories about their lives, paralyzed p...
