Annie Jump Cannon, Astronomer

"Parents and teachers ask me for the names of books for their primary school children. I'm honored to recommend Annie Jump Cannon, Astronomer by Carole Gerber, an excellent book about a true astronomical pioneer." -Paul Kohlmiller, editor, San Jose Astronomical Association newsletter This brilliantly illustrated children's book depicts the achievements of a woman who developed an important system of classifying stars. To this day, Annie Jump Cannon holds the record for identifying more stars than anyone else in the world. In 1925, she became a professor of astronomy at Harvard and the first woman to receive a doctor of science degree from Oxford University. Born during the Civil War, Cannon was determined to pursue a career in astronomy. From her childhood days of studying the constellations with her mother, to her education at Wellesley College and her job in the Harvard Observatory, this biography follows Cannon's inspirational path to success. The story notes the challenges the astronomer faced, such as an illness that left her partially deaf and gender discrimination, while capturing her shining moments as she worked to become the "census-taker of the stars."

The Annihilation of Nature: Human Extinction of Birds and Mammals

Environmental scientists reveal the victims of humanity’s massive assault on nature.Gerardo Ceballos, Anne H. Ehrlich, and Paul R. Ehrlich serve as witnesses in this trial of human neglect, where the charge is the massive and escalating assault on living things. Nature is being annihilated, not only because of the human population explosion, but also as a result of massive commercial endeavors and public apathy. Despite the well-intentioned work of conservation organizations and governments, the authors warn us that not enough is being done and time is short for the most vulnerable of the world's wild birds and mammals. Thousands of populations have already disappeared, other populations are dwindling daily, and soon our descendants may live in a world containing but a minuscule fraction of the birds and mammals we know today.The Annihilation of Nature is a clarion call for engagement and action. These outspoken scientists urge everyone who cares about nature to become personally connected to the victims of our inadequate conservation efforts and demand that restoration replace destruction. Only then will we have any hope of preventing the worst-case scenario of the sixth mass extinction.

The Annotated and Illustrated Double Helix

Published to mark the fiftieth anniversary of the Nobel Prize for Watson and Crick's discovery of the structure of DNA, an annotated and illustrated edition of this classic book gives new insights into the personal relationships between James Watson, Frances Crick, Maurice Wilkins, and Rosalind Franklin, and the making of a scientific revolution.

The Annotated and Illustrated Double Helix

Published to mark the 50th anniversary of the Nobel Prize for Watson and Crick's discovery of the structure of DNA, an annotated and illustrated edition of this classic book gives new insights into the personal relationships between James Watson, Frances Crick, Maurice Wilkins, and Rosalind Franklin, and the making of a scientific revolution. In his 1968 memoir, The Double Helix, the brash young scientist James Watson chronicled the drama of the race to identify the structure of DNA, a discovery that would usher in the era of modern molecular biology. Alexander Gann and Jan Witkowski have built upon this gripping narrative, juxtaposing Watson's racy account with the observations of other protagonists and offering an enhanced perspective on the now legendary story of Watson and Crick's discovery. Gann and Witkowski have mined many sources, including a trove of newly discovered correspondence belonging to Francis Crick (mislaid some fifty years ago) and the archives of Maurice Wilkins, Linus Pauling, Rosalind Franklin, and Watson and Crick themselves. Also in this edition are Watson's own account of the Nobel Prize award and celebrations, appendixes that include an account of the book's controversial first publication, and a chapter dropped from the original edition, as well as an extraordinary assortment of documents and photographs-- many never before published. This wealth of material contributes depth and color to Watson's novelistic text and places events in their contemporary scientific and social context. After half a century, the implications of the double helix keep rippling outward; the tools of molecular biology have forever transformed the life sciences and medicine. The Annotated and Illustrated Double Helix adds new richness to the account of the momentous events that led the charge.

Annual, Lunar, and Tidal Clocks: Patterns and Mechanisms of Nature's Enigmatic Rhythms

There is more to biological rhythms than circadian clocks. This book aims at promoting the exciting potential of a deeper understanding of circannual, circatidal, and circalunar clocks. It highlights new developments, summarizes existing knowledge, and integrates different perspectives with the tools and ideas of diverse fields of current biology. For predominantly pragmatic reasons, research in recent decades was mostly concerned with circadian clocks. Clocks on other timescales, however, have been largely neglected and therefore still appear "enigmatic". Thanks to the rapid development of methods in molecular biology as well as in ecology, we are now able to re-approach these clocks. Laboratories around the world are showing fresh interest and substantial progress is being made in many independent projects. The book's two sections address the moon-derived circatidal, circasemilunar, and lunar cycles on the one hand (10 chapters), and the sun-derived circannual cycles on the other (6 chapters). This work brings together authors with an expansive array of expertise and study systems, ranging from tidal cycles of marine invertebrates to annual cycles of birds and mammals, and from behavioral to genetic and epigenetic backgrounds. While great challenges remain to be mastered, the book aims at conveying the excitement of unraveling, broadly, the rhythms of life.

Anoikis: How the Extracellular Matrix Regulates Life-or-Death Decisions

Anoikis is defined broadly as apoptosis that is inhibited by appropriate cell-matrix interactions. Normal and tumor cells vary widely in their sensitivity to anoikis, but, in general, metastatic tumor cells are inevitably anoikis-resistant. In particular, tumor cells that possess a cancer stem cell or mesenchymal phenotype, arising from the oncogenic Epithelial-Mesenchymal Transition (EMT), are transcriptionally re-programmed to resist anoikis. While the anoikis response occurs through the mitochondrial pathway typically found in other apoptotic responses (e.g., DNA damage, death receptors, oxidative stress), the regulation of anoikis by cell-matrix signalling is unique and only partially characterized. The uniqueness of anoikis is: a. regulation by integrins, non-integrin matrix receptors, and the signaling complexes associated with them; b. regulation by metabolic changes occurring in response to attachment/detachment; c. regulation by oncogenes and tumor suppressor genes d. regulation by tumor microenvironment; e. regulation by EMT.

Anomalies and Curiosities of Medicine

Anomalous Effects in Simple Metals

Using potassium as an example, this work presents a unique approach to the anomalous effects in metals, resulting in knowledge that can be applied to similar materials. Most theoretical predictions on the electric, magnetic, optical, and thermal properties of a simple metal do - surprisingly - not agree with experimental behavior found in alkali metals. The purpose of this volume is to document the many phenomena that have violated expectations. It collects in one place the research by Albert Overhauser, one of the pioneers of the field. His and his collaborators work has led to a unified synthesis of alkali metal peculiarities. The unique collection of 65 reprint papers, commented where necessary to explain the context and perspective, is preceded by a thorough and well paced introduction. The book is meant to advanced solid state physics and science historians. It might also serve as additional reading in advanced solid state physics courses. With a foreword by Mildred and Gene Dresselhaus

The Anomalous Magnetic Moment of the Muon

This book reviews the present state of knowledge of the anomalous magnetic moment a=(g-2)/2 of the muon. The muon anomalous magnetic moment is one of the most precisely measured quantities in elementary particle physics and provides one of the most stringent tests of relativistic quantum field theory as a fundamental theoretical framework. It allows for an extremely precise check of the standard model of elementary particles and of its limitations.
