Why Aren T They Here

A calm, intelligent and witty survey of the history of mankind's search for extraterrestial life.

A NEW YORK TIMES BESTSELLER “Brilliant and enthralling.”​ —The Wall Street Journal A paradigm-shifting book from an acclaimed Harvard Medical School scientist and one of Time’s most influential people. It’s a seemingly undeniable truth that aging is inevitable. But what if everything we’ve been taught to believe about aging is wrong? What if we could choose our lifespan? In this groundbreaking book, Dr. David Sinclair, leading world authority on genetics and longevity, reveals a bold new theory for why we age. As he writes: “Aging is a disease, and that disease is treatable.” This eye-opening and provocative work takes us to the frontlines of research that is pushing the boundaries on our perceived scientific limitations, revealing incredible breakthroughs—many from Dr. David Sinclair’s own lab at Harvard—that demonstrate how we can slow down, or even reverse, aging. The key is activating newly discovered vitality genes, the descendants of an ancient genetic survival circuit that is both the cause of aging and the key to reversing it. Recent experiments in genetic reprogramming suggest that in the near future we may not just be able to feel younger, but actually become younger. Through a page-turning narrative, Dr. Sinclair invites you into the process of scientific discovery and reveals the emerging technologies and simple lifestyle changes—such as intermittent fasting, cold exposure, exercising with the right intensity, and eating less meat—that have been shown to help us live younger and healthier for longer. At once a roadmap for taking charge of our own health destiny and a bold new vision for the future of humankind, Lifespan will forever change the way we think about why we age and what we can do about it.

Just a rehearsal and of the possibilities if in the dissolution of an illusion by the extraordinary we realize the amazing of not being alone in the universe. And that it would be totally different and extremely good of what we had never imagined. From a modest and humble reflection, I consider it useful for each one of us to find out about ourselves and what is inside. Maybe the answer and all the others are not out there, but inside us, and that has always been so, since we are divine sparks. We just forget and find it hard to realize. Through discovery we will be exponentially better and so much so that it is difficult to comprehend in this limited existence of ours what can be afterwards.

An increasing number of poor Southern Africans live in poverty-stricken urban slums or shantytowns. Focusing on four shantytowns in the northern Namibian town of Oshakati, this book analyses the coping strategies of the poorest sections of such populations. The study is based on fieldwork conducted intermittently during a period of ten years. It combines theories of political, economic and cultural structuration, and of the material and cultural basis for social relations of inclusion and exclusion as practise. The poorest shanty dwellers are marginalised or excluded from vital urban and rural relationships and forced into social relations of poverty amongst themselves. Having experienced long-term processes of impoverishment, the very poorest and most destitute in the shantytowns tend to give up improving their lives and act in ways that further undermine their position.

THE ALIENS ARE AMONG US! “Where is everybody?” Nobel Prize-winning physicist Enrico Fermi once asked after a discussion about the possibility of intelligent life elsewhere in the universe. To sum up the Fermi Paradox, if the billions of stars in our galaxy have planets with intelligent life on them, why hasn’t anyone visited us? But maybe they have, and we just haven’t noticed—and that’s the way they want it. And if they are here in secret, why are they here? Are they tourists? Anthropologists, perhaps? Or journalists sending stories back about the quaint habits of the primitives? Or maybe the extraterrestrial equivalent of hunters or fishermen? (Any odd disappearances in your neighborhood lately?) An enemy already within the gates? Or a refugee seeking sanctuary? Gourmets looking for exotic foreign food? Alien criminals hiding out? Alien cops looking for those alien criminals? No missionaries—at least not yet—and there doesn’t seem to be a Galactic Peace Corps. They might happen to look close enough to human to pass, or they might be masters of disguise. Or they might be so incomprehensibly different that we don’t even notice that they’re here. The secret visitors are revealed by such luminaries as Larry Niven, Poul Anderson, Spider Robinson, William Tenn, and more. And if any alien visitors want to check out the local natives’ speculations herein, feel free. Please pay with local currency, of course.

Praise for previous anthologies edited by Hank Davis: About Time Troopers: "The editors’ mastery of the military SF and time travel subgenres is evident in their thoughtful selections. Fans of literate speculative fiction will hope for more from these experts." —Publishers Weekly Cosmic Corsairs: “Who doesn’t like space pirates? (Well, their victims I guess, but that’s beside the point.) . . . Hank Davis has a fine sense for choosing a wide mix of stories, and this book is no exception. No story is like another, yet they manage to form a whole greater than the parts. From sapient ships to piratical sibling rivalry, pirate detectives to ingenious captives seeking freedom, from alien biology to orbital mechanics, the stories share some of the same elements—pragmatic thinking, moral complexity, loyalty, and betrayal. Definitely a fun one." —Analog In Space No One Can Hear You Scream: “[T]he 13 tales in this collection blend sf with horror to demonstrate the resiliency of both genres . . . offers strong tales by the genre’s best storytellers.” —Library Journal “[F]irst-rate science fiction, demonstrating how short stories can still entertain.” —The Galveston County Daily News A Cosmic Christmas 2 You: “This creative and sprightly Christmas science fiction anthology spins in some surprising directions. . . . A satisfying read for cold winter evenings . . . a great stocking stuffer for SF fans.” —Publishers Weekly As Time Goes By: “As Time Goes By . . . does an excellent job of exploring not only romance through time travel—relationships enabled or imperiled by voyaging through time—but the intrinsic romance of time travel itself. . . . The range of styles and approaches is as wide as the authors' sensibilities and periods might suggest . . . full of entertaining and poignant stories . . . ” —Alvaro Zinos-Amaro, IntergalacticMedicineShow.com About Star Destroyers, coedited by Christopher Ruocchio: “. . . spectacular space battles and alien contacts . . . themes of military ethics, the uses of artificial intelligence, and the limits of the capacity of the human mind. . . . it is the human interactions and decisions that ultimately drive the stories. . . . will appeal to fans of military and hard science fiction and any readers fascinated by the possibilities of space travel." —Booklist “. . . stories of giant spaceships at war, at peace, and in the often-gray areas between. . . . a worthy addition to a long tradition of ship-based fiction, and its authors portray captains, arcane astrogators, and civilian child passengers with equal depth. It’s recommended for fans of military SF and space adventure." —Publishers Weekly “. . . you’d probably expect some tight, action-filled space opera stories of giant space battles . . . and there’s some of that. But there are also espionage stories, rescue missions, political conflicts, alternate histories, even a few humorous tales. . . . each author took the premise in a different direction . . . if I had to identify one common feature to all the stories, it would be that they’re all fun. . . . Like it says, big ships blowing things up. What’s not to like?" —Analog
