Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

Most books about the history of humanity pursue either a historical or a biological approach, but Dr. Yuval Noah Harari breaks the mold with this highly original book. From examining the role evolving humans have played in the global ecosystem to charting the rise of empires, Sapiens integrates history and science to reconsider accepted narratives, connect past developments with contemporary concerns, and examine specific events within the context of larger ideas.

Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate following. Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent of the speed of light? How fast can you hit a speed bump while driving and live? If there were a robot apocalypse, how long would humanity last?

Bill Bryson once again proves himself to be an incomparable companion as he guides us through the human body - how it functions, its remarkable ability to heal itself, and (unfortunately) the ways it can fail. Full of extraordinary facts (your body made a million red blood cells since you started reading this) and irresistible Bryson-esque anecdotes, The Body will lead you to a deeper understanding of the miracle that is life in general and you in particular. As Bill Bryson writes, "We pass our existence within this wobble of flesh and yet take it almost entirely for granted."

For decades the practice of manifestation has been widely dismissed as self-involved, materialistic pseudoscience. But as neuroscientist and recognized compassion leader Dr. James Doty reveals, manifestation introduces us to different possibilities, and it lays the groundwork for a kinder, better world. Doty grounds us in the practices that change our brain structures: attention, meditation, visualization, and compassion. This mind magic allows us to move through the world in ways that help us see clearly.

Since it was first published in 2005, Ray Kurzweil's The Singularity Is Near and its vision of the future have been influential in spawning a worldwide movement with millions of followers, hundreds of books, major films, and thousands of articles. During the succeeding decade, many of Kurzweil's predictions about technological advancements have been borne out, and their viability has become familiar to the public through such now commonplace concepts. In this entirely new book Ray Kurzweil brings a fresh perspective to advances in the singularity.

The Real Anthony Fauci details how Fauci, Gates, and their cohorts use their control of media outlets, scientific journals, key government and quasi-governmental agencies, global intelligence agencies, and influential scientists and physicians to flood the public with fearful propaganda about COVID-19 virulence and pathogenesis, and to muzzle debate and ruthlessly censor dissent.

As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.

There is nothing more essential to our health and well-being than breathing. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences.

The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices.

Stark narrates a series of outdoor adventure stories in which thrill can cross the line into mortal peril. Each death or brush with death is at once a suspense story, a cautionary tale, and a medical thriller. He describes what goes through the mind of a cross-country skier as his body temperature plummets - apathy at 91 degrees, stupor at 90 - and explores the physiology of a snowboarder trying not to panic as he consumes the tiny pocket of air trapped around his face under thousands of pounds of snow.
