Download or read book The Sky Was Ours written by Joe Fassler and published by Penguin. This book was released on 2024-04-23 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: “An immersive fever dream of a novel, beautifully written and boldly imagined.” —Leslie Jamison, New York Times bestselling author of The Empathy Exams From prizewinning writer Joe Fassler comes a brilliant modern reimagining of the myth of Daedalus and Icarus as a story of obsession, longing, and the radical pursuit of utopia It’s 2005, and 24-year-old Jane is miserable. Overworked, buried in debt, she senses the life she wanted slipping away—while the world around her veers badly off course, hurtling toward economic and ecological collapse. She wants to find something better. But she has no idea where to start. In a sudden and unprecedented burst of rebellion, Jane decides to abandon everything she knows, leaving behind her relationships and responsibilities to go on the road. That’s how she meets Barry, a brilliant and charismatic recluse living on an isolated homestead near New York’s Canadian border. For years, in secret, Barry’s chased an unlikely obsession: to build a pair of wings humans can fly in, with designs inspired by an obscure precursor to the Wright Brothers. It’s no mere hobby. He’s convinced his dream of flight will spark a revolution, delivering us from the degradation of modern capitalism and the climate chaos that awaits us. Jane is captivated by Barry’s radical vision, even as his experiments become more dangerous. But she’s equally drawn to the enigmatic Ike, Barry’s gentle, thoughtful son, who’s known no other reality—and who only wants to keep his father alive, tethered to ground and to reason. So begins an inventive, dazzlingly beautiful story about the human desire for transcendence—our longing to escape the mundane and glide into a euphoric future. Inspired by the myth of Daedalus and Icarus, The Sky Was Ours is a powerful and imaginative debut that explores the question: If you had access to technology that allowed you to escape the confines of your life, would you use it? And if Barry’s wings really could change the world, would that be freedom?
Download or read book Great Transformations in Vertebrate Evolution written by Kenneth P. Dial and published by University of Chicago Press. This book was released on 2015-07-20 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the history of life; events that have captured the imagination of scientists and the general public alike. At first glance, these major evolutionary events seem utterly impossible. The before and after look so fundamentally different that the great transformations of the history of life not only seem impossible, but unknowable. The 500 million year history of vertebrates is filled with change and, as a consequence, every living species contains within its structure, DNA, and fossil record, a narrative of them. A battery of new techniques and approaches, from diverse fields of inquiry, are now being marshaled to explore classic questions of evolution. These approaches span multiple levels of biological organization, from DNA sequences, to organs, to the physiology and ecology of whole organisms. Analysis of developmental systems reveals deep homologies of the mechanisms that pattern organs as different as bird wings and fish fins. Whales with legs are one of a number of creatures that tell us of the great transformations in the history of life. Expeditions have discovered worms with a kind of head, fishes with elbows, wrists, and necks; feathered dinosaurs, and human precursors to name only a few. Indeed, in the last 20 years, paleontologists have discovered more creatures informative of evolutionary transitions than in the previous millennium. "The Great Transformations "captures the excitement of these new discoveries by bringing diverse teams of renowned scientists together to attack particular transformations, and to do so in a contents organized by body part--head, neck, fins, limbs, and then the entire bauplan. It is a work that will transform evolutionary biology and paleontology."
Download or read book The Vasopressin System and Behavior written by Heather K. Caldwell and published by Frontiers Media SA. This book was released on 2018-11-16 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vasopressin and its homologues are evolutionarily ancient neuropeptides that are important to the neural modulation of behavior in many species. Over the last several decades there has been an emergence of cross-species consensus with regards to the broad behavioral domains that the vasopressin system influences. However, there are nuanced species- and sex-differences in the functions of this system, as well as evidence for cross-talk between this system and the oxytocin system. For this Research Topic, reviews and research articles from investigators across the field were solicited, with the goal to highlight some of the complexity and diversity within this system. This collection challenges researchers to broaden their understanding of this system as well as identifies areas in which additional research is needed. Topic areas featured include: - System complexity - Sex and species differences - Developmental effects - Human and non-human primates

Download or read book Frontiers in Invertebrate Physiology A Collection of Reviews written by Saber Saleuddin and published by CRC Press. This book was released on 2024-02-13 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new 3-volume set provides informative reviews on the physiology of sponges, cnidarians, round and flat worms, annelids, echinoderms, and crustaceans, advancing our knowledge of the physiology of these major invertebrate groups (Phyla). Invertebrates exhibit the largest number of species and occupy virtually every conceivable ecological niche. They are economically important in food chains, they recycle organic waste, and they are crucial pollinators of plants and sources of food. They are also medically relevant as parasites that cause major diseases in both humans and livestock. Volume 1 looks at non-Bilaterians (sponges, cnidarians, placozoans). The focus on sponge biology has recently been on symbiosis, nutrient uptake, and sensory biology. The section on cnidarians covers biomineralization, the nervous system, and development. The biology of placozoans is described in depth, including the role of neuropeptides in feeding. Volume 2 and covers crustacean physiology and diverse physiological topics, ranging from molting, respiration, water balance, biomineralization, bioreceptors, and temperature regulation to the land adaptation of terrestrial crustaceans. Echinoderms and annelids are covered in Volume 3.

Download or read book A Comparative Survey of the RF amide Peptide Superfamily written by Karine Rousseau and published by Frontiers Media SA. This book was released on 2015-12-16 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery, twelve years ago, that the RF-amide peptide kisspeptin, acting via GPR54, is essential for the onset of puberty and reproduction, has been a major breakthrough in reproductive physiology. It has also put in front of the spotlights RF-amide peptides and allowed to revive research on this superfamily. The first member of this family to be characterized, in 1977, was the cardioexcitatory peptide, FMRFamide, isolated from the ganglia of the clam Macrocallista nimbosa. Since then, a large number of these peptides, designated after their C-terminal arginine (R) and amidated phenylalaline (F) residues, have been identified in representative species of all major phyla. By means of phylogenetic analyses, the superfamily of RFamide peptides has been divided into five families in vertebrates: kisspeptin, QFRP (including 26RFa), LPXRFa (including GnIH and RFRP), PQRFa (including NPFF) and PrRP. Recent data reveal that SIFamide-type neuropeptides in protostomian invertebrates and SALMFamide-type neuropeptides in deuterostomian invertebrates share a common evolutionary origin with vertebrate LPXRFa and PQRFa. Interestingly, in invertebrates as in vertebrates, multiple genes, as well as multiple mature peptides, are often present in a single species, questioning the need for such diversity in term of function. Comparative studies on non-mammalian vertebrates and invertebrates allow major advances in the knowledge of the evolutionary history of the RF-amide peptide superfamily. Such phylogenetical studies also contribute to improve classification and nomenclature of both peptides and receptors. RF-amide peptides from different families have major evolutionary conserved roles in the control of reproduction, but also of food intake, metabolism, energy expenditure, cardiovascular function, nociception and stress. They are also involved in the integration of environmental signals, notably the photoperiod, to regulate reproduction. For instance, in most vertebrate species and especially in seasonal mammals, kisspeptin and GnIH/RFRP have complementary but opposite effects in the control of reproductive function. In addition, recent data show cross-activities between the members of the RF-amide peptide superfamily and their receptors. For example, PrRP, kisspeptin and 26RFa are able to modulate nociception via NPFF receptors. Comparative studies have the potential to reveal novel regulatory mechanisms that could give a better comprehension of physiological functions and lead to new therapeutic treatments for related human pathologies. Thus, kisspeptin antagonists have been developed as novel tools for treatment of hormone-dependent disorders of reproduction such as precocious puberty and endometriosis or kisspeptin agonists for treatment of infertility, in humans. Studies on lower vertebrate models can also contribute to the discovery of new roles of these peptides, as seen recently with kisspeptin being involved in the early development of the medaka. This research topic will aim at gathering major advances achieved through comparative studies in (mammalian and non-mammalian) vertebrates and invertebrates, in the knowledge of RF-amide peptides in term of evolutionary history and physiological roles.
