Rachel Louise Carson, noted biologist and environmentalist who fascinated readers with three books on the wonders of the sea and awakened the American public to the dangers of pesticide misuse with a highly controversial bestseller, was born on May 27, 1907, in Springdale, Pennsylvania. She was interested in writing at an early age and submitted a number of juvenile stories, poems, and essays to leading youth magazines. Rachel Carson's first book, Under the Sea Wind , attracted little notice on its appearance in 1941. However, her second book on the sea, The Sea Around Us (1951), remained on the best-seller lists for eighty-six weeks, was eventually translated into thirty languages, and received many awards.

    Introduction DrMetcalf provides online access to information on cicadas , leafhoppers , planthoppers , spittlebugs , and treehoppers , including a searchable bibliographic database for retrieving literature on these groups, which together comprise the group Auchenorrhyncha . The database includes nearly 12,000 early publications (1741-1955). Few electronic databases cover the early literature for any insect group. Because the focal groups are common and widespread, users may find the database helpful for retrieving many older works on insects in general. DrMetcalf also includes an overview of the group Auchenorrhyncha and each of its major subgroups.

History of Medicine In 1816, an Englishwoman still in her teens, Mary Shelley, conceived the story of a scientist obsessed with creating life. Shelley's scientist, Victor Frankenstein, succeeds. But while Frankenstein's creature can think and feel, he is monstrous to the eye. Spurned by all, including Victor Frankenstein himself, the embittered creature turns into a savage killer. In 1818, Shelley's story was published as Frankenstein; or, The Modern Prometheus . This story — both in the original novel and shaped into new forms, such as plays, films, and comics — has captivated people ever since, exposing hidden, sometimes barely conscious fears of science and technology.

History of Medicine Instruction in Surgery. Five physicians and their colleagues in the surgical amphitheatre of the Massachusetts General Hospital watch as the anesthetist administers ether to a patient who is about to have surgery. This illustration appeared in an 1889 issue of Harper's Weekly . The National Library of Medicine was originally established 150 years ago, in 1836, as the Library of the Army Surgeon General's Office. Perhaps the key event in the library's history occurred in 1865, when Dr. John Shaw Billings became director. For the next 30 years he worked tirelessly to expand the library's holdings and open it as a source of biomedical information for all physicians.

The History of Medicine Division of the National Library of Medicine has a rich collection of illustrated anatomical atlases dating from the 15th to the 20th century. The Historical Anatomies on the Web Project has been designed to broaden access to this collection by providing high-resolution downloadable scans of selected important images from the atlases. Atlases and images have been chosen for their historical and artistic significance by the project's content coordinator, Michael North. Important images may be omitted if the atlas is damaged or fragile, or if the work is bound in such a way as to impede high quality scanning. A priority has been placed upon scanning the earliest and/or the best edition of a work in Library's possession. The scans generally omit text.

History of Medicine Introduction The horse has been one of the most important animals throughout human history, and healing horses has had an important place in veterinary and medical literature. Theories about equine physiology and health often mirrored theories about humans, and the literature of both was inherently linked. Bloodletting, astrology, and ancient texts were used by both physicians and veterinarians to heal their patients, and many discoveries, including the circulation of the blood, developed in tandem. The Hippiatrica: Ancient Texts Medieval and Renaissance veterinary medicine looked to ancient veterinary texts for its inspiration, just as physicians for human healing did.

History of Medicine Home > From 'Monsters' to Modern Medical Miracles Home > Embryology and Classification of Conjoined Twins Embryology of Conjoined Twins Identical twins develop when a single fertilized egg, also known as a monozygote, splits during the first two weeks of conception. Conjoined twins form when this split occurs after the first two weeks of conception. The monozygote does not fully separate and eventually develops into a conjoined fetus that shares one placenta, one amniotic sac, and one chorionic sac. Because the twins develop from a single egg, they will also be the same sex. The extent of separation and the stage at which it occurs determine the type of conjoined twin, i.e., where and how the twins will be joined.

History of Medicine Rewriting the Book of Nature Charles Darwin and Evolutionary Theory Charles Darwin’s vision—“from so simple a beginning, endless forms most beautiful and most wonderful have been, and are being evolved”—now forms the foundation of the biological sciences. Radical in sweep, Darwin’s idea of naturally innovating and endlessly changing webs of life undercut all previous sciences. Darwin was instantly seen as a potent sign of a new science, a new way of conceiving the world. His theory was an immediate threat not just to those who were wedded to an older conception, but to all who relied on a given and settled order for meaning and for power.

Overview While theoretical biology is often understood to be primarily mathematical in nature, biology is an inherently historical science with a long tradition of conceptual theorizing, from Charles Darwin to the architects of the Modern Synthesis, and continuing through to today. Biological disciplines ranging from evolutionary biology to ecology, from cell to developmental biology, and from morphology to paleobiology are characterized by a lively interplay among empirical data, mathematical treatments, and conceptual discussions. Like theoretical biology, philosophy of biology is characterized by its attention to conceptual issues.

The Great Lakes and their connecting channels from the largest aggregation of freshwater on the planet (excluding the polar ice caps). The watershed includes parts or all of eight U.S. states and the Canadian province of Ontario. The Lakes are the dominant and defining geological characteristic of the upper Midwest, affecting the social, economic, recreational and ecological life of the region. Bordering as it does on four of the five Great Lakes, the State of Michigan and its universities understand the importance of the Lakes for the future vitality of our state. Accordingly the University of Michigan has pursued an active research program in this area, and seeks to share some of its findings through this site.

Dental Cosmos, a Monthly Record of Dental Science was the first enduring national journal for the American dental profession, and one of the most significant in the early history of American dentistry. The foundation of dental practice was documented and debated in its pages from 1859 through 1936, when it merged with the Journal of the American Dental Association , serving as a cornerstone for JADA and the model of what a successful dental journal could be. Many of these original source articles are still cited and considered classics in the field. The conversion of Dental Cosmos (1859 to 1936) from print to electronic was made possible through the generous support of the Colgate-Palmolive Company. Last update December 4, 2006.
