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.

    Researchers are delving into the mysteries of stem cells and the human genome, discovering what it means to grow old and how to keep those processes from happening. This isn't science fiction; it's real, it's serious, and it's on track to revolutionize our definitions of life and mortality.In Immortality, Inc., veteran science journalist Chip Walter gains exclusive access to the champions of this radical cause, delivering a book that brings together for the first time the visions of molecular biologist and Apple chairman Arthur Levinson, genomics entrepreneur Craig Venter, futurist Ray Kurzweil, rejuvenation trailblazer Aubrey de Grey, and stem cell expert Robert Hariri. Along the way, Walter weaves in fascinating conversations about life, death, aging, and the future of the human race.

    Their first intimation of our existence might well be a Super Bowl broadcast or a stray transmission from the Playboy channel. But, of course, they might seem equally strange to us. How strange? Their senses could be entirely different from ours—they might see in the infrared or “hear” radio waves.What would aliens look like? An intelligent octopus-like creature is certainly plausible. What about odd numbers of limbs—a three-legged alien with three arms and three eyes? What about an entire planet of immobile, silicon-based “trees” that communicate with each other via electrical signals?The Science of Aliens gets weirder still. Could a giant interstellar cloud be “alive” and intelligent? Could creatures live at extremely high pressures and temperatures? And which of these many possibilities would be similar enough to us that they could communicate with them, or they with us? Would they have any interest in abducting us? Would they want to have sex with us?In classic Pickover style, here is speculation at the far edge of knowledge—and beyond.

    Believing that regional cuisine reveals far more than just our taste for chicken fried steak or 3-way chili, Richman explores the ethnic, economic, and cultural factors that shape the way we eat—and how food, in turn, reflects who we are as a nation. Richman uses his signature wit and casual charm to take youon a tour around the country,explaining such curiosities as why bagels are shaped like circles, why fried chicken is so popular in the South, and how some of the most iconic American food—hot dogs, fries, and soda—are not really American at all. Writing with passion, curiosity, and a desire to share his knowledge, he includes recipes, secret addresses for fun and tasty finds, and tips on how to eat like a local from coast to coast.Part travelogue, part fun fact book, part serious culinary journalism, Richman's America the Edible illuminates the food map in a way nobody has before.

    Through metaphors and straightforward language, it breathes life into astrophysics, unveiling how particles and forces and fields interplay to create the drama in the heavens above us.

    Now in its 12th edition, it is still the market leader and is known for its scientific research base and its currency, comprehensiveness, and accuracy.

    But things didn't turn out that way. For a start, we turned out to have far fewer genes than originally thought - just over 20,000, the same sort of number as a fruit fly or worm. What's more, the proportionof DNA consisting of genes coding for proteins was a mere 2%. So, was the rest of the genome accumulated 'junk'?Things have changed since those early heady days of the Human Genome Project. But the emerging picture is if anything far more exciting. In this book, John Parrington explains the key features that are coming to light - some, such as the results of the international ENCODE programme, still much debated and controversial in their scope. He gives an outline of the deeper genome, involving layers of regulatory elements controlling and coordinating the switching on and off of genes; the impact ofits 3D geometry; the discovery of a variety of new RNAs playing critical roles; the epigenetic changes influenced by the environment and life experiences that can make identical twins different and be passed on to the next generation; and the clues coming out of comparisons with the genomes ofNeanderthals as well as that of chimps about the development our species. We are learning more about ourselves, and about the genetic aspects of many diseases. But in its complexity, flexibility, and ability to respond to environmental cues, the human genome is proving to be far more subtle than we ever imagined.

    Almost everyone leaves at least one tip every day. More than five million American workers depend on them, and we spend $66 billion on tips each year. And everyone recognizes that queasy feeling - in bars and restaurants, barbershops and beauty parlors, hotels and strip clubs, and everywhere else - when the check arrives or the tip jar looms. Omnipresent yet poorly understood, tipping has worked its way into almost every part of daily life. In Keep the Change, bestselling author Steve Dublanica dives into this unexplored world, in a comical yet serious attempt to turn himself into the Guru of the Gratuity. As intrepid and irreverent as Michael Moore or A. J. Jacobs, Dublanica travels the country to meet shoeshine men, strippers, bartenders, bellhops, bathroom attendants, and many others, all in an effort to overcome his own sweaty palms when faced with those perennial questions: Should I tip? How much? Throughout he explores why tipping has spread; he explains how differences in gender, age, ethnicity, and nationality affect our attitudes; and he reveals just what the cabdriver or deliveryman thinks of us after we've left a tip. Written in the lively style that made Waiter Rant such a hit, Keep the Change is a fun and enlightening quest that will change the way we think - and tip.

    We may know a bit about Napoleon or Joan of Arc or Louis XIV, but for most of us that's about it. In my own three schools we were taught only about the battles we won: Crécy and Poitiers, Agincourt and Waterloo. The rest was silence. So here is my attempt to fill in the blanks... John Julius Norwich (at 88) has finally written the book he always wanted to write, the extremely colourful story of the country he loves best. From frowning Roman generals and belligerent Gallic chieftains, to Charlemagne (hated by generations of French children taught that he invented schools) through Marie Antoinette and the storming of the Bastille to Vichy, the Resistance and beyond, FRANCE is packed with heroes and villains, adventures and battles, romance and revolution. Full of memorable stories and racy anecdotes, this is the perfect introduction to the country that has inspired the rest of the world to live, dress, eat -- and love better.
