Where PiHKAL focuses on a class of compounds called phenethylamines, TiHKAL is written about a family of psychoactive drugs known as tryptamines with TiHKAL being an acronym for Tryptamines I Have Known and Loved”. Like its predecessor, this book is divided into two parts. The first part of the book begins with the story of Alice and Shura, a fictionalized autobiography, which picks up where the similar section of PiHKAL left off. The book opens with the story about the DEA raid that occurred a few years after the publication of their first book, PiHKAL.

"What should we have for dinner?" To one degree or another, this simple question assails any creature faced with a wide choice of things to eat. Anthropologists call it the omnivore's dilemma. Choosing from among the countless potential foods nature offers, humans have had to learn what is safe, and what isn't. Today, as America confronts what can only be described as a national eating disorder, the omnivore's dilemma has returned with an atavistic vengeance.

After Hurricane Katrina struck and power failed, amid rising floodwaters and heat, exhausted staff at Memorial Medical Center designated certain patients last for rescue. Months later, a doctor and two nurses were arrested and accused of injecting some of those patients with life-ending drugs.

One of the greatest scientific feats of our era is the astonishing progress made in understanding biology-the intricate machinery of life-a progress to which the period we are living in right now has contributed the most.As you read these words, researchers are delving ever deeper into the workings of living systems, turning their discoveries into new medical treatments, improved methods of growing food, and innovative products that are already changing the world.

Most mothers have experienced exhaustion, pain, forgetfulness, indecision, low energy levels, moodiness, or some form of baby brain. And it's no wonder: The process of growing a baby depletes a mother's body in substantial ways. But with postnatal care ending after six weeks, most women never learn how to rebuild their strength and care for their bodies after childbirth. As a result, they can suffer from the effects of depletion for many years, without knowing what's wrong as well as getting the support and treatments that they need.

New hope for those suffering from conditions like depression, anxiety, bipolar disorder, addictions, PTSD, ADHD, and more. Though incidence of these conditions is skyrocketing, for the past four decades standard treatment hasn’t much changed, and success rates in treating them have barely improved, either. Meanwhile, the stigma of the “mental illness” label - damaging and devastating on its own - can often prevent sufferers from getting the help they need. Brain specialist and best-selling author Dr. Daniel Amen aims to change all that.

David Quammen's book, The Song of the Dodo, is a brilliant, stirring work, breathtaking in its scope, far-reaching in its message - a crucial book in precarious times, which radically alters the way in which we understand the natural world and our place in that world.

In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries.

Before the Pilgrims landed at Cape Cod, what was happening in North America? Who was there? What civilizations rose and fell? For years, the answers to these questions have been shrouded in mystery. At the time of European contact, a diverse world of Native peoples thrived across the continent. What was their backstory? Who were the ancestors of the Sioux? Where did the Navajo come from? What about the Apache, the Comanche, the Cherokee?

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

Forced to accept that intensive farming on the heavy clay of their land at Knepp was economically unsustainable, Isabella Tree and her husband, Charlie Burrell, made a spectacular leap of faith: they decided to step back and let nature take over. Thanks to the introduction of free-roaming cattle, ponies, pigs and deer - proxies of the large animals that once roamed Britain - the 3,500 acre project has seen extraordinary increases in wildlife numbers and diversity in little over a decade.

Raging ambition. Towering egos. Competition under a veneer of courtesy. Heroic effort combined with plagiarism, theft, exaggeration, and fraud. This was the state of bird study in eastern North America during the early 1800s, as a handful of intrepid men raced to find the last few birds that were still unknown to science. The most famous name in the bird world was John James Audubon, who painted spectacular portraits of birds. But although his images were beautiful, creating art was not his main goal. Instead, he aimed to illustrate (and write about) as many different species as possible.

In Other Minds, Peter Godfrey-Smith, a distinguished philosopher of science and a skilled scuba diver, tells a bold new story of how subjective experience crept into being—how nature became aware of itself. As Godfrey-Smith stresses, it is a story that largely occurs in the ocean, where animals first appeared.

In what he says is the most important piece of environmental writing in his long and award-winning career, Mark Kurlansky, best-selling author of Salt and Cod, The Big Oyster, 1968, and Milk, among many others, employs his signature multi-century storytelling and compelling attention to detail to chronicle the harrowing yet awe-inspiring life cycle of salmon.

When it comes to climate change, the media, politicians, and other prominent voices have declared that "the science is settled." In reality, the long game of telephone from research to reports to the popular media is corrupted by misunderstanding and misinformation. Core questions - about the way the climate is responding to our influence, and what the impacts will be - remain largely unanswered. The climate is changing, but the why and how aren't as clear as you've probably been led to believe.

In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.

The United States, Russia, China, and other countries around the world have experienced contact with the phenomenon, as we will discover in War. Americans demand that their leaders reveal what they know. They demand disclosure. But what do our allies, and our enemies, know about the phenomenon and why have they not already disclosed? Why is this an international issue, and not just an American one? And what does that tell us about the phenomenon?
