A child of immigrants, Abdul El-Sayed grew up feeling a responsibility to help others. He threw himself into the study of medicine and excelled—winning a Rhodes Scholarship, earning two advanced degrees, and landing a tenure-track position at Columbia University. At age thirty, he became the youngest city health official in America, tasked with rebuilding Detroit’s health department after years of austerity policies. But El-Sayed found himself disillusioned. He could heal the sick—even build healthier and safer communities—but that wouldn’t address the social and economic conditions causing illness in the first place. So he left health for politics, running for governor of Michigan and earning the support of progressive champions like Congresswoman Alexandria Ocasio-Cortez and Senator Bernie Sanders. In Healing Politics, El-Sayed traces the life of a young idealist, weaving together powerful personal stories and fascinating forays into history and science. Marrying his unique perspective with the science of epidemiology, El-Sayed diagnoses an underlying epidemic afflicting our country, an epidemic of insecurity. And to heal the rifts this epidemic has created, he lays out a new direction for the progressive movement. This is a bold, personal, and compellingly original book from a prominent young leader.Voir livre

Come along on an informative, whirlwind tour of urban species and discover that you are surrounded by wild nature, even in your own backyard. When biologist Hanna Bjørgaas spots a fairy cup lichen in Antarctica, she is surprised to recognize it from her own backyard in Oslo. When she returns home, she embarks on a journey into urban nature, visiting city parks, cemeteries, and concrete rooftops to investigate the species that live in urban spaces. Along the way, she meets corvids, songbirds, ants, pigeons, bats, sparrows, fungi, and linden trees—and the experts who study their surprising abilities to survive, and thrive, in the city. As Bjørgaas discovers, urban nature—and its unique mixture of species that have never lived together before in Earth's history—is valuable. More than half of the world's human population lives in densely populated areas—and plants and animals have followed us into cities. Secret Life of the City invites us to pay more attention to the sounds, sights, and smells of urban nature right outside our door. A treasure trove of fascinating flora and fauna, this wonderful book offers a plea to save our city plants, animals, and fungi before we lose them, too.Voir livre

With employers offering free flu shots and pharmacies expanding into one-stop shops to prevent everything from shingles to tetanus, vaccines are ubiquitous in contemporary life. The past fifty years have witnessed an enormous upsurge in vaccines and immunization in the United States: American children now receive more vaccines than any previous generation, and laws requiring their immunization against a litany of diseases are standard. Yet, while vaccination rates have soared and cases of preventable infections have plummeted, an increasingly vocal cross section of Americans have questioned the safety and necessity of vaccines. In Vaccine Nation, Elena Conis explores this complicated history and its consequences for personal and public health. Vaccine Nation opens in the 1960s, when government scientists—triumphant following successes combating polio and smallpox—considered how the country might deploy new vaccines against what they called the “milder” diseases, including measles, mumps, and rubella. In the years that followed, Conis reveals, vaccines fundamentally changed how medical professionals, policy administrators, and ordinary Americans came to perceive the diseases they were designed to prevent. She brings this history up to the present with an insightful look at the past decade’s controversy over the implementation of the Gardasil vaccine for HPV, which sparked extensive debate because of its focus on adolescent girls and young women. Through this and other examples, Conis demonstrates how the acceptance of vaccines and vaccination policies has been as contingent on political and social concerns as on scientific findings. By setting the complex story of American vaccination within the country’s broader history, Vaccine Nation goes beyond the simple story of the triumph of science over disease and provides a new and perceptive account of the role of politics and social forces in medicine.Voir livre
This audiobook is narrated by an AI Voice. What is consciousness, and why does it matter? Is it a byproduct of the brain, a reflection of the cosmos, or the very fabric of reality itself? Consciousness – Where Did It Come From and Where Is It Going? takes listeners on a profound journey through the mysteries of awareness, exploring both the science and the spirit of mind. From leading theories such as Integrated Information Theory and Global Workspace Theory, to deeper explorations of memory, dreams, the self, and even the quantum question, this audiobook illuminates the many faces of consciousness. It traces the evolution of awareness - from the earliest stirrings of life’s inner eye, to the possibility of a universal consciousness shaping the cosmos. With clarity and depth, the chapters reveal consciousness as both a scientific puzzle and a timeless mystery. Is the self an illusion? Can dreams open gateways to hidden dimensions of mind? What role does the body play in shaping awareness? And most importantly, what might the future of consciousness hold for humanity and beyond? Whether you are fascinated by neuroscience, intrigued by philosophy, or drawn to the spiritual dimensions of mind, this audiobook offers a sweeping exploration of one of the greatest questions of existence: Where did consciousness come from - and where is it going?Voir livre
