    K. C. Cole's "Fun with Physics" is a profile of astrophysicist Janet Conrad that blends her personal life with professional activity. In "Desperate Measures," the doctor and writer Atul Gawande profiles the surgeon Francis Daniels Moore, whose experiments in the 1940s and '50s pushed medicine harder and farther than almost anyone had contemplated. Also included is a poem by the legendary John Updike, "Mars as Bright as Venus." The collection ends with Diane Ackerman's "ebullient" essay "We Are All a Part of Nature."Together these twenty-three articles on a wide range of today's most current topics in science -- from biology, physics, biotechnology, and astronomy, to anthropology, genetics, evolutionary theory, and cognition‚ represent the full spectrum of scientific writing from America's most prominent science authors, proving once again that "good science writing is evidently plentiful" (Scientific American).

    Prusiner received a Nobel Prize, the world's most prestigious award for achievement in physiology or medicine. That he was the sole recipient of the award for the year was entirely appropriate, for his struggle to identify the agent responsible for ravaging the brains of animals suffering from scrapie and mad cow disease, and of humans with Creutzfeldt-Jakob disease, had been waged largely alone and in some cases in the face of strenuous disagreement.   In this book, Prusiner tells the remarkable story of his discovery of prions—infectious proteins that replicate and cause disease but surprisingly contain no genetic material—and reveals how superb and meticulous science is actually practiced using talented teams of researchers who persevere. He recounts the frustrations and rewards of years of research and offers fascinating portraits of his peers as they raced to discover the causes of fatal brain diseases. Prusiner’s hypothesis, once considered heresy, now stands as accepted science and the basis for developing diagnoses and eventual cures. He closes with a meditation on the legacy of his discovery: What will it take to cure Alzheimer’s, Parkinson’s, Lou Gehrig’s and other devastating diseases of the brain?

Offering a fascinating and compelling insight into a popular area of social history, this easy-to-read introduction will tell you all you need to know about disease and the ongoing quest to protect human health.

    We’ll look at what identical twins can teach us about the epigenetic effects of our environment and experiences, why certain genes are 'switched on' or off at various stages of embryonic development, and how scientists have reversed the specialization of cells to clone frogs from a single gut cell. In Introducing Epigenetics, Cath Ennis and Oliver Pugh pull apart the double helix, examining how the epigenetic building blocks and messengers that interpret and edit our genes help to make us, well, us.

    Whether the ailment is a cold, the flu, diabetes, obesity or certain cancers, the likely cause is germs. Our ancient enemies have four families - bacteria, viruses, fungi, and protozoa - and many names: Ebola, E. coli, salmonella, norovirus, gonorrhea. . . Human beings are engaged in a "war on germs," in which we develop ever-more sophisticated weapons and defensive strategies. But it is a war we can never win. Our best plan for staying as healthy is to choose our battles carefully, and try to co-exist with germs as best we can. The Germ Code is a wise, witty and wonderfully readable guide to our relationship with these infinitesimal but infinitely powerful creatures. Microbiologist Jason Tetro takes us outside the lab and shows the enormous influence of germs upon humanity's past, present and future. He unlocks the mysteries of "the germ code" to reveal how these organisms have exploited our every activity and colonized every corner of the earth. From his own research and personal experience, Tetro relates how the most recent flu pandemic happened, how others may have been averted and how more may come about if we aren't careful. He also explains that not every germ is our foe, and offers advice on harnessing the power of good germs to stay healthy and make our planet a better place. The Germ Code is a fascinating journey through an unseen world, an essential manual to living in harmony with germs and a life-enhancing (as well as life-saving!) good read.

    Judy Mikovits and Kent Heckenlively, this book reviews the evidence for and against widespread public masking as provided by the Centers for Disease Control and the Mayo Clinic, as well as top scientific publications such as the New England Journal of Medicine and The Lancet. This debate needs to take place without fear and paranoia. Important questions raised in this book are the affect of masks on oxygen and carbon dioxide levels, how SARS-CoV-2 spreads, the effectiveness of various types of masks, those who are most vulnerable to COVID-19, and whether our children should go back to school in the fall, and if so, what measures they should take.The authors' previous book, PLAGUE OF CORRUPTION, was the runaway science bestseller of 2020, and the authors bring that same passion and attention to detail to the mask question. As politicians and bureaucrats of all stripes are weighing in on this question, with some placing their cities and states under mandatory masking provisions, we need to understand the science behind their decisions. Are such measures a reasonable response to current circumstances, or is it a dramatic overreach, which in many cases might make the situation even worse? America desperately needs this public conversation to take place with the best science we have available. As Americans have always done during difficult times, we must summon the courage to have these challenging conversations.

    In the midst of all this death, a bizarre disease appeared in Europe. Eventually known as encephalitis lethargica, or sleeping sickness, it would spread across the world, leaving millions dead or locked in institutions. Then, in 1927, it would disappear as suddenly as it had arrived-or so the doctors at first thought. Asleep, set in 1920s and '30s New York, follows a group of neurologists through hospitals and insane asylums as they try to solve this worldwide epidemic. The symptoms could include not only unending sleep but dangerous insomnia, facial tics, catatonia, Parkinson's, and even violent insanity. Molly Caldwell Crosby, acclaimed author of The American Plague, explores the frightening history of this forgotten disease- and details the frantic effort to conquer it before it strikes again.

    How many of us understand the way seizures affect the brain, how the heart is connected to wellbeing, or the why the foot carries the key to our humanity? In Adventures in Human Being, award-winning author Gavin Francis leads readers on a journey into the hidden pathways of the human body, offering a guide to its inner workings and a celebration of its marvels.Drawing on his experiences as a surgeon, ER specialist, and family physician, Francis blends stories from the clinic with episodes from medical history, philosophy, and literature to describe the body in sickness and in health, in living and in dying. At its heart, Adventures in Human Being is a meditation on what it means to be human. Poetic, eloquent, and profoundly perceptive, this book will transform the way you view your body.

    But nowhere is this drive to do better more important than in medicine, where lives are on the line with every decision. In his new book, Atul Gawande explores how doctors strive to close the gap between best intentions and best performance in the face of obstacles that sometimes seem insurmountable. Gawande's gripping stories of diligence, ingenuity, and what it means to do right by people take us to battlefield surgical tents in Iraq, to labor and delivery rooms in Boston, to a polio outbreak in India, and to malpractice courtrooms around the country. He discusses the ethical dilemmas of doctors participation in lethal injections, examines the influence of money on modern medicine, and recounts the astoundingly contentious history of hand washing. And as in all his writing, Gawande gives us an inside look at his own life as a practicing surgeon, offering a searingly honest firsthand account of work in a field where mistakes are both unavoidable and unthinkable. At once unflinching and compassionate, Better is an exhilarating journey narrated by arguably the best nonfiction doctor-writer around (Salon). Gawande's investigation into medical professionals and how they progress from merely good to great provides rare insight into the elements of success, illuminating every area of human endeavor.
