Book excerpt: In the gripping start to this young adult science fiction adventure series by popular Colorado radio host Dom Testa, the teenage crew of the starship Galahad must find a new home for humanity among the stars--if they fail, it will be the end of the human race.... When the tail of the comet Bhaktul flicks through the Earth's atmosphere, deadly particles are left in its wake. Suddenly, mankind is confronted with a virus that devastates the adult population. Only those under the age of eighteen seem to be immune. Desperate to save humanity, a renowned scientist proposes a bold plan: to create a ship that will carry a crew of 251 teenagers to a home in a distant solar system. Two years later, the Galahad and its crew—none over the age of sixteen—is launched. Two years of training have prepared the crew for the challenges of space travel. But soon after departing Earth, they discover that a saboteur is hiding on the Galahad! Faced with escalating acts of vandalism and terrorized by threatening messages, sixteen-year-old Triana Martell and her council soon realize that the stowaway will do anything to ensure that the Galahad never reaches its destination. The teens must find a way to neutralize their enemy. For if their mission fails, it will mean the end of the human race....

Download or read book The Comet written by W. E. B. Du Bois and published by Graphic Arts Books. This book was released on 2021-06-08 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Comet (1920) is a science fiction story by W. E. B. Du Bois. Written while the author was using his role at The Crisis, the official magazine of the NAACP, to publish emerging black artists of the Harlem Renaissance, The Comet is a pioneering work of speculative fiction which imagines a catastrophic event not only decimating New York City, but bringing an abrupt end to white supremacy. “How silent the street was! Not a soul was stirring, and yet it was high-noon—Wall Street? Broadway? He glanced almost wildly up and down, then across the street, and as he looked, a sickening horror froze in his limbs.” Sent to the vault to retrieve some old records, bank messenger Jim Davis emerges to find a city descended into chaos. A comet has passed overhead, spewing toxic fumes into the atmosphere. All of lower Manhattan seems frozen in time. It takes him a few moments to see the bodies, piled into doorways and strewn about the eerily quiet streets. When he comes to his senses, he finds a wealthy woman asking for help. Soon, it becomes clear that they could very well be the last living people in the planet, that the fate of civilization depends on their ability to come together, not as black and white, but as two human beings. But how far will this acknowledgment take them? With a beautifully designed cover and professionally typeset manuscript, this edition of W. E. B. Du Bois’ The Comet is a classic work of African American literature reimagined for modern readers.

Book excerpt: David Levy brings these "ghostly apparitions" to life. With fascinating scenarios both real and imagined, he shows how comets have wreaked their special havoc on Earth and other planets. Beginning with ground zero as comets take form, we track the paths their icy, rocky masses take around our universe and investigate the enormous potential that future comets have to directly affect the way we live on this planet and what we might find as we travel to other planets. In this extraordinary volume, David Levy shines his expert light on a subject that has long captivated our imaginations and fears, and demonstrates the need for our continued and rapt attention.
Download or read book The Comet Seekers written by Helen Sedgwick and published by HarperCollins. This book was released on 2016-10-11 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: A magical, intoxicating debut novel, both intimate and epic, that intertwines the past, present, and future of two lovers bound by the passing of great comets overhead and a coterie of remarkable ancestors. Róisín and François are immediately drawn to each other when they meet at a remote research base on the frozen ice sheets of Antarctica. At first glance, the pair could not be more different. Older by a few years, Róisín, a daughter of Ireland and a peripatetic astronomer, joins the science team to observe the fracturing of a comet overhead. François, the base’s chef, has just left his birthplace in Bayeux, France, for only the second time in his life. Yet devastating tragedy and the longing for a fresh start, which they share, as well as an indelible but unknown bond that stretches back centuries, connect them to each other. Helen Sedgwick carefully unfolds their surprisingly intertwined paths, moving forward and back through time to reveal how these lovers’ destinies have long been tied to each other by the skies—the arrival of comets great and small. In telling Róisín and François’s story, Sedgwick illuminates the lives of their ancestors, showing how strangers can be connected and ghosts can be real, and how the way we choose to see the world can be as desolate or as beautiful as the comets themselves. A mesmerizing, skillfully crafted, and emotionally perceptive novel that explores the choices we make, the connections we miss, and the ties that inextricably join our fates, The Comet Seekers reflects how the shifting cosmos unite us all through life, beyond death, and across the whole of time.
Download or read book 30 years of the Comet Assay an overview with some new insights written by Amaya Azqueta and published by Frontiers Media SA. This book was released on 2015-08-21 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: By means of this ‘Frontiers in Genetics’ research topic, we are celebrating 30 years of the Comet Assay. The first paper on this single-cell gel electrophoresis assay was published in 1984 by O. Ostling and K.J. Johanson (Biochem. Biophys. Res. Commun. Vol.123: 291-298). The comet assay is a versatile and sensitive method for measuring single - and double-strand breaks in DNA. By including lesion-specific enzymes in the assay, its range and sensitivity are greatly increased, but it is important to bear in mind that their specificity is not absolute. The comet assay (with and without inclusion of lesion-specific enzymes) is widely used as a biomarker assay in human population studies - primarily to measure DNA damage, but increasingly also to assess the capacity of cells for DNA repair. Ostling and Johanson (Biochem. Biophys. Res. Commun., 1984) were also the first to report experiments to measure DNA repair, by simply following the decrease of DNA damage over time after challenging cells with ionising radiation. However, this approach is time-consuming and laborious as it requires an extended period of cell culture and is therefore not ideal for biomonitoring studies, which typically require high-throughput processing of many samples. As an alternative approach, the in vitro comet-based repair assay was developed: a cell extract is incubated with a DNA substrate containing specific lesions, and DNA incisions accumulate. The in vitro comet-based repair assay has been modified and improved over the past decade: it was first devised to measure base excision repair of oxidised purines in lymphocytes (Collins et al., Mutagenesis, 2001), but has since been adapted for other lesions and thus other repair pathways, as well as being applied to tissue samples in addition to cell suspensions. Even after 30 years, the comet assay is still in a growth phase, with many new users each year. Many questions are repeatedly raised, which may seem to have self-evident answers, but clearly, it is necessary to reiterate them for the benefit of the new audience, and sometimes being forced to think again about old topics can shed new light. Different applications of the comet assay are discussed in this special issue, including: genotoxicity testing in different organisms, human biomonitoring, DNA repair studies, environmental biomonitoring and clinical studies. Furthermore, we consider and where possible answer questions, including the ones raised by Raymond Tice at the 8th International Comet Assay Workshop in Perugia (Italy 2009): What is the spectrum of DNA damage detected by the various versions of the comet assay?; What are the limitations associated with each application?; What should be done to standardize the assay for biomonitoring studies?; Can the comet assay be used to monitor changes in global methylation status?; What cell types are suitable for detecting genotoxic substances and their effects in vivo and in vitro?; Can the assay be fully automated?; and more. So this ‘Frontiers in Genetics’ research topic is written for the beginner as well as for the experienced users of the comet assay.

Book excerpt: What are these graceful visitors to our skies? We now know that they bring both life and death and teach us about our origins. Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark. Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed? Lavishly illustrated with photographs and specially commissioned full-color paintings, Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why. Praise for Comet "Simply the best." —The Times of London "Fascinating, evocative, inspiring." —The Washington Post "Comet humanizes science.
