Why is the genome of a salamander 40 times larger than that of a human? Why does the avocado tree produce a million flowers and only a hundred fruits? Why, in short, is there so much waste in nature? In this lively and wide-ranging meditation on the curious accidents and unexpected detours on the path of life, Daniel Milo argues that we ask these questions because we’ve embraced a faulty conception of how evolution - and human society - really works.

Informed by cutting-edge scientific research and sparkling with memorable characters - from the modern druids who worship at Stonehenge each solstice to the Amish farmers who may have the right idea about healthy sleep patterns - Linda Geddes’s Chasing the Sun analyzes all aspects of our relationship to the sun. The fascinating stories, innovative science, and unique perspectives in this book make it clear that the ancients were right to put the sun at the center of our world and that it is crucial that we remember this bond as we shape our lives today.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

Some 73,000 years ago, the Mount Toba supervolcano in toda's Indonesia erupted, releasing the energy of a million tons of explosives. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop for a decade. In this book, Donald R. Prothero presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide.

The Martians explores the CIA's top-secret search for the Martians, multiple photos of strange anomalies, and the latest revelations about the environment and water on Mars. And most tantalizing of all: Did an ailing Martian race come to Earth in past eons and were they confused with gods? The questions concerning life on Mars - then and now - are many. The answers are astounding.

Climate change manifests in many ways across America, but few as dramatic as the attacks on our western pine forests. In Trees in Trouble, Daniel Mathews tells the urgent story of this loss, accompanying burn crews and forest ecologists as they study the myriad risk factors and refine techniques for saving this important, limited resource.

Over the years, color has dazzled, enhanced, and clarified the world we see. The experimental palettes of painting, the advent of the color photograph, Technicolor pictures, color printing, and so on have created a vivid and vibrant continuum. These ways of representing reality in “living color” echo our evolutionary reliance on and indeed privileging of color as a complex and vital form of consumption, classification, and creation. It’s everywhere we look, yet do we really know much of anything about it?

The subject of infection and how to fight it grows more urgent every day. How do pathogens cause disease? And what tools can we give our bodies to do battle? Dr. John S. Tregoning has dedicated his career to answering these questions. Infectious uncovers fascinating success stories in immunology and virology, making this book not only a vital overview of infection but also a hopeful history of human ingenuity.

Multiple sclerosis. Parkinson’s disease. Alzheimer’s. ALS. Chances are that you know someone with a neurologic disease. Because the brain controls so much and is integral to our identity, the diseases that affect it are uniquely devastating both to patients and families. And because it remains the most mysterious of our vital organs, treating the brain is an ongoing puzzle.

Instead of a great island of trash, the infamous Great Pacific Garbage Patch is made up of manmade debris spread over hundreds of miles of sea - more like a soup than a floating garbage dump. Recycling is more complicated than we were taught: Less than nine percent of the plastic we create is reused, and the majority ends up in the ocean. And plastic pollution isn’t confined to the open sea: It’s in much of the air we breathe and the food we eat.

How is it that we can walk unfamiliar streets while maintaining a sense of direction? How can we come up with shortcuts on the fly, in places we've never traveled? The answer is the complex mental map in our brains. This feature of our cognition is easily taken for granted, but it's also critical to our species' evolutionary success. In From Here to There, Michael Bond tells stories of the lost and found - Polynesian sailors, orienteering champions, early aviators - and surveys the science of human navigation.

One cannot turn on the news today without a report on an extreme-weather event or the latest update on Antarctica. But while our politicians argue, the truth is that climate change is already here. Nobody knows this better than Indigenous peoples, who, having developed an intimate relationship with ecosystems over generations, have observed these changes for decades. For them, climate change is not an abstract concept or policy issue, but the reality of daily life.

Two hours to cover 26 miles and 385 yards. Its running's Everest, a feat once seen as impossible for the human body. Now we can glimpse the mountaintop. The sub-two-hour marathon requires an exceptional feat of speed, mental strength, and endurance. The pioneer will have to endure more, live braver, plan better, and be luckier than any who has run before. Ed Caesar takes us into the world of elite runners: the greatest marathoners on Earth.

A strong memory and healthy brain aren't as difficult to maintain as one might think; combining the latest neuroscience research with age-old wisdom about resilience, mindfulness, and stress reduction, Drs. Henry Emmons and David Alter show that vibrant aging is within reach.

Filled with catchall research, American Hemp examines what this new domestic crop can be used for, what makes it a superior product, and what made it illegal in the first place; the book also delves into the many health and medical benefits of the plant. Hobbs weighs in on how hemp can improve existing industries, from farming to energy to 3D printing, plus how it can make a serious impact on climate change by removing toxins from the soil and by decreasing our dependence on plastics and fossil fuels.

With all the advances in science in the last century, why are there still so many infectious diseases? Why haven’t we found cures for difficult cancers? Why hasn’t any major progress been made in the treatment of mental illness? And how do we intend to stop, and not only that but reverse, global warming and the climate crisis? In Saved by Science, scientist Mark Poznansky examines the many crises facing humanity while encouraging us with the promise of an emerging solution: synthetic biology.
