Crab Wars PDF Author: William Sargent
Publisher: University Press of New England
ISBN: 1611687160
Category : Nature
Languages : en
Pages : 100

Book Description
Surviving almost unmolested for 300 million years, the horseshoe crab is now the object of an intense legal and ethical struggle involving marine biologists, environmentalists, US government officials, biotechnologists, and international corporations. The source of this friction is the discovery 25 years ago that the blood of these ancient creatures serves as the basis for the most reliable test for the deadly and ubiquitous gram-negative bacteria. These bacteria are responsible for life-threatening diseases like menengitis, typhoid, E. coli, Legionnaire's Disease and toxic shock syndrome. Because every drug certified by the FDA must be tested using the horseshoe crab derivative known as Limulus lysate, a multimillion dollar industry has emerged involving the license to "bleed" horseshoe crabs and the rights to their breeding grounds. Since his youthful fascination with these ancient creatures, William Sargent has spent much of his life observing, studying, and collecting horseshoe crabs. As a result, he presents a thoroughly accessible insider's guide to the discovery of the lysate test, the exploitation of the crabs at the hands of multinational pharmaceutical conglomerates, local fishing interests, and the legal and governmental wrangling over the creatures' ultimate fate. In the end, the story of the horseshoe crab is a sobering reflection on the unintended consequences of scientific progress and the danger of self-regulated industries controlling a limited natural resource.

Book Description
A timely look at the exploitation of a species that has helped with the development of countless drugs and is fast becoming endangered. Because every drug certified by the FDA must be tested using the horseshoe crab derivative known as Limulus lysate, a multimillion-dollar industry has emerged involving the license to bleed horseshoe crabs and the rights to their breeding grounds. William Sargent presents a thoroughly accessible insider's guide to the discovery of the lysate test, the exploitation of the horseshoe crab at the hands of multinational pharmaceutical conglomerates, local fishing interests, and the legal and governmental wrangling over the creatures' ultimate fate. In the end, the story of the horseshoe crab is a sobering reflection on the unintended consequences of scientific progress and the danger of self-regulated industries controlling a limited natural resource. This new edition brings the story up to date as companies race to manufacture alternatives to the horseshoe crab blood, which is now essential for testing vaccines such as those being developed to counter COVID-19. However, horseshoe crab populations are still dwindling, with profound implications not only for the future of the crabs themselves but also for the ecosystems that depend on them.

Pages : 177

Book Description
What is a crab? What significance do crabs play in the world? In Crab, Cynthia Chris reveals that these charming creatures are social by nature, creative problem-solvers, and invaluable members of the environments in which they live. Their formidable physical forms, their hard-to-harvest and quick-to-spoil flesh, and their sassy demeanor have inspired artists and writers from Vincent van Gogh to Jean-Paul Sartre. Chris sketches vivid portraits of these animals, tracing the history of the crab through its ancient fossil record to its essential role in protecting its own habitats from the threat of climate change.

ISBN: 9780983011187
Category : Limulus polyphemus
Languages : en
Pages : 0

Book Description
Traveling from the Delaware Bay to the Florida Panhandle, this examination is a quest through the natural history and science behind one of nature's oldest and oddest survivors--the horseshoe crab. With ten eyes, five pairs of walking legs, a heart half the length of their bodies, and blood that can save a person's life, horseshoe crabs have been on this planet for 445 million years--since long before the dinosaurs arrived. This book explores their unique biology and sex life, explains their importance to medical science and migratory shorebirds, and introduces readers to the people who are working to study and protect them.

Endotoxin Detection and Control in Pharma, Limulus, and Mammalian Systems

Endotoxin Detection and Control in Pharma, Limulus, and Mammalian Systems PDF Author: Kevin L. Williams
Publisher: Springer
ISBN: 3030171485
Category : Medical
Languages : en
Pages : 869

Book Description
Endotoxin detection and control is a dynamic area of applied science that touches a vast number of complex subjects. The intersection of test activities includes the use of an ancient blood system from an odd “living fossil” (Limulus). It is used to detect remnants of the most primitive and destructive forms of life (prokaryotes) as contaminants of complex modern systems (mammalian and Pharma). Recent challenges in the field include those associated with the application of traditional methods to new types of molecules and manufacturing processes. The advent of “at will” production of biologics in lieu of harvesting animal proteins has revolutionized the treatment of disease. While the fruits of the biotechnology revolution are widely acknowledged, the realization of the differences in the means of production and changes in the manner of control of potential impurities and contaminants in regard to the new versus the old are less widely appreciated. Endotoxin as an ancient, dynamic interface between lifeforms, provides a singular perspective from which to view the parallel development of ancient and modern organisms as well as the progress of man in deciphering the complexity of their interactions in his efforts to overcome disease.

Moonbird

Moonbird PDF Author: Phillip Hoose
Publisher: Farrar, Straus and Giroux (BYR)
ISBN: 146686706X
Category : Juvenile Nonfiction
Languages : en
Pages : 160

Book Description
B95 can feel it: a stirring in his bones and feathers. It's time. Today is the day he will once again cast himself into the air, spiral upward into the clouds, and bank into the wind. He wears a black band on his lower right leg and an orange flag on his upper left, bearing the laser inscription B95. Scientists call him the Moonbird because, in the course of his astoundingly long lifetime, this gritty, four-ounce marathoner has flown the distance to the moon—and halfway back! B95 is a robin-sized shorebird, a red knot of the subspecies rufa. Each February he joins a flock that lifts off from Tierra del Fuego, headed for breeding grounds in the Canadian Arctic, nine thousand miles away. Late in the summer, he begins the return journey. B95 can fly for days without eating or sleeping, but eventually he must descend to refuel and rest. However, recent changes at ancient refueling stations along his migratory circuit—changes caused mostly by human activity—have reduced the food available and made it harder for the birds to reach. And so, since 1995, when B95 was first captured and banded, the worldwide rufa population has collapsed by nearly 80 percent. Most perish somewhere along the great hemispheric circuit, but the Moonbird wings on. He has been seen as recently as November 2011, which makes him nearly twenty years old. Shaking their heads, scientists ask themselves: How can this one bird make it year after year when so many others fall? National Book Award–winning author Phillip Hoose takes us around the hemisphere with the world's most celebrated shorebird, showing the obstacles rufa red knots face, introducing a worldwide team of scientists and conservationists trying to save them, and offering insights about what we can do to help shorebirds before it's too late. With inspiring prose, thorough research, and stirring images, Hoose explores the tragedy of extinction through the triumph of a single bird. Moonbird is one The Washington Post's Best Kids Books of 2012. A Common Core Title.

Basking with Humpbacks

Basking with Humpbacks PDF Author: Todd McLeish
Publisher: University Press of New England
ISBN: 1611689953
Category : Nature
Languages : en
Pages : 234

Book Description
Basking with Humpbacks offers an exciting, close-up look at some of the most rare marine creatures living in New England waters and examines the complex threats they face. In eleven chapters, each featuring a different animal or plant, McLeish takes readers on an entertaining journey with scientists who study these species. The author follows basking sharks - the second largest fish in the sea - in their hunt for food, helps harbor porpoises escape from fishing nets, snorkels in search of wild bay scallops, and learns how the blood of horseshoe crabs is used in medical research. Along the way he visits the islands where rare seabirds nest, tracks humpback whales on their long migration to the Gulf of Maine, and watches as stranded leatherback turtles are returned to the ocean. These first-person experiences are coupled with interviews with biologists and other experts who explain in their own words the important role these creatures play in the marine ecosystem and what steps must be taken to protect them. In examining the natural history of selected plants and animals, McLeish also discusses the physics of waves and currents, the geology of the seabed, the chemistry of sea water, and other natural factors that influence the survival of New England marine life.
