Dr. Folkman's War: Angiogenesis and the Struggle to Defeat Cancer
by Robert CookeIn 1961, twenty-eight-year-old Dr. Judah Folkman saw something while doing medical research in a United States navy lab that gave him the first glimmering of a wild, inspired hunch. What if cancerous tumors, in order to expand, needed to trigger the growth of new blood vessels to feed themselves? And if that was true, what if a way could be found to stop that growth? Could cancers be starved to death? Dr. Folkman had ample reason to be self confident -- second in his class at Harvard Medical School, he was already considered one of the most promising doctors of his generation. But even he never guessed that his idea would eventually grow into a multibillion-dollar industry that is now racing through human trials with drugs that show unparalleled promise of being able to control cancer, as well as other deadly diseases. For the creation of this book, Dr. Judah Folkman cooperated fully and exclusively with acclaimed science writer Robert Cooke. He granted Cooke unlimited interviews, showed him diaries and personal papers, and threw open the doors of his lab. The result is an astonishingly rich and candid chronicle of one of the most significant medical discoveries of our time and of the man whose vision and persistence almost single-handedly has made it possible. Dr. Folkman's radical new way of thinking about cancer was once considered preposterous. So little was known about how cancer spreads and how blood vessels grow that he wasn't even taken seriously enough to be considered a heretic. Other doctors shook their heads at the waste of a great mind, and ambitious young medical researchers were told that accepting a position in Folkman's lab would be the death of their careers. Now, though, the overwhelming majority of experts believes that the day will soon come when antiangiogenesis therapy supplants the current more toxic and less-effective treatments -- chemotherapy, radiation, and surgery-as the preferred method of treatment for cancer in patients around the world, and Dr. Folkman's breakthrough will come to be taken for granted the way we now take for granted the polio vaccine and antibiotics. Dr. Folkman's War brilliantly describes how high the odds are against success in medical research, how vicious the competition for grants, how entrenched the skepticism about any genuinely original thinking, how polluted by politics and commerce the process of getting medicine into patients' hands. But it also depicts with rare power how exalted a calling medicine can be and how for the rare few--the brilliant, the tireless, and the lucky -- the results of success can be world-changing. From the Hardcover edition.

Dr. Space
by Bob WardWritten by veteran aerospace journalist Bob Ward, who spent years investigating his subject, this biography presents a revealing but even-handed portrait of the father of modern rocketry. As he chronicles Wernher von Braun's life, Ward explodes many myths and misconceptions about the controversial genius who was a hero to some, a villain to others. The picture of von Braun that emerges is of a brilliant scientist with limitless curiosity and a drive to achieve his goals at almost any price from, developing the world's first ballistic missile used against the Allies in World War II to helping launch the first U.S. satellite that hurled Americans into space and the Saturn V super-booster that powered them to the moon. Along the way readers are introduced to the human side of this charismatic visionary who brought the United States into the Space Age.
Dr Space Junk vs The Universe: Archaeology and the Future (The\mit Press Ser.)
by Alice GormanA pioneering space archaeologist explores artifacts left behind in space and on Earth, from moon dust to Elon Musk's red sports car.Alice Gorman is a space archaeologist: she examines the artifacts of human encounters with space. These objects, left behind on Earth and in space, can be massive (dead satellites in eternal orbit) or tiny (discarded zip ties around a defunct space antenna). They can be bold (an American flag on the moon) or hopeful (messages from Earth sent into deep space). They raise interesting questions: Why did Elon Musk feel compelled to send a red Tesla into space? What accounts for the multiple rocket-themed playgrounds constructed after the Russians launched Sputnik? Gorman—affectionately known as “Dr Space Junk” —takes readers on a journey through the solar system and beyond, deploying space artifacts, historical explorations, and even the occasional cocktail recipe in search of the ways that we make space meaningful.Engaging and erudite, Gorman recounts her background as a (nonspace) archaeologist and how she became interested in space artifacts. She shows us her own piece of space junk: a fragment of the fuel tank insulation from Skylab, the NASA spacecraft that crash-landed in Western Australia in 1979. She explains that the conventional view of the space race as “the triumph of the white, male American astronaut” seems inadequate; what really interests her, she says, is how everyday people engage with space. To an archaeologist, objects from the past are significant because they remind us of what we might want to hold on to in the future.

Drachenzucht für Einsteiger: Ein "gefährlicher" Zeitvertreib für Hobby-Genetiker
by Paul Knoepfler Julie KnoepflerKann man einen Drachen züchten? Kann er dann Feuer spucken und fliegen? Können wir ihm eine eindrucksvolle Größe verleihen? Wie schlau sollen wir unseren Drachen machen, und können wir ihn trainieren? Wie wahrscheinlich ist es, dass wir bei unserem Versuch, einen Drachen zu bauen, umkommen? Und geht das auch mit Einhörnern?Die Welt begeistert sich seit Jahrhunderten für Drachen und sie haben noch immer einen festen Platz in der Popkultur wie Smaug in „Der kleine Hobbit“ und die Drachen in „Game of Thrones“. Die Leute lieben Drachen und sind neugierig zu erfahren, ob man tatsächlich einen Drachen erschaffen kann. In diesem ungewöhnlichen Buch geht es darum, wie wir mit den allerneuesten wissenschaftlichen Techniken theoretisch einen Drachen erschaffen könnten. Dabei behandeln wir modernste wissenschaftliche Themen wie CRISPR, Biohacking, Stammzellenforschung und Bioengineering. Das Buch steckt voller Fakten, doch der Humor kommt nicht zu kurz, und es regt Leser*innen überdies an, sich Gedanken über den Einfluss von Wissenschaft und Technik auf unsere Gesellschaft zu machen. Unterwegs wirft das Buch einen satirischen Blick auf die Wissenschaft an vorderster Front, die oft in den Medien maßlos gehypt wird. Es diskutiert Schlüsseltechnologien, die ins Spiel kommen, wenn wir uns vorstellen, unsere Idee, einen Drachen zu bauen, in feuerspuckende Realität umzusetzen. Während wir all diese Themen diskutieren, sprechen wir auch über die ethischen Probleme, die sich beim „Bau“ eines Drachens ergeben, und die Möglichkeiten, einen ähnlichen Ansatz zu nutzen, um andere mythische Wesen, wie z.B. ein Einhorn, zu erschaffen. Dieses Buch, das jeden ansprechen sollte, enthält viele eindrucksvolle Illustrationen und andere interessante Abbildungen, darunter Drachendarstellungen, Bilder von Flugsaurierskeletten und vieles mehr.

Dragon Songs: Love and Adventure among Crocodiles, Alligators, and Other Dinosaur Relations
by Vladimir DinetsA born naturalist and a fearless traveler, Vladimir Dinets wrote travel guides, conducted field research, and lived a couple of lives before he was accepted into the PhD program in zoology at the University of Miami. He thought crocodiles were a dead-end research topic--survivors from the age of the dinosaurs but not much else--until he witnessed groups of up to seventy alligators performing mating choruses that included infrasound vibrations--a form of communication extremely rare in nature--and a "dance" unknown in the scientific literature but that resembled a scene from Jurassic Park. To prove his thesis about the language of crocodiles, he spent the next six years traveling around the world on shoestring budgets and in extreme circumstances, studying almost every living species. At the same time, as a man desiring companionship in life, he sought love.With adventures on five continents, Dragon Songs is his account of this quest. It includes an escape from a boiling lava lake in the Afar Desert, being chased up a tree by a tiger in India, hitching a ride with a cocaine smuggler in Bolivia, and diving with giant Greenland sharks--all in the name of studying crocodiles, among which he routinely paddled in his inflatable kayak. Of course, not everything went according to plan. But, in the end, his ground-breaking research helped change the field. And during the course of his adventures, he met and courted his future wife.
Dragon Walk: On Reef Recovery & Political Will
by Robert WintnerThe three main hubs of aquarium trade devastation are Indonesia, the Philippines, and Hawaii. Each has its own sad story of political corruption and theft of natural resources to benefit a greedy, ruthless few. Yet, despite facing a litany of challenges, each hub shows faint hope for progress: with Komodo National Park in Indonesia, a few bright lights in the development of Philippine reef management, and an anti-aquarium campaign taking hold in Hawaii. A beautiful coffee table photo book is one thing. Dragon Walk is a political grenade, willing to name culprits, political assassins, and nitwits with less spinal fortitude than most invertebrates. Dragon Walk is far more vital; a no-holds-barred grapple with evil and reef devastation that shines a light where others fear to tread.
