While cells are commonly considered the building block of living things, it is actually the communication between cells that brings us to life, controlling our bodies and brains, determining whether we are healthy or sick, and directly influencing how we think, feel, and behave. In The Secret Language of Cells, doctor and neuroscientist Jon Lieff lets us listen in on these conversations, and reveals their significance for everything from mental health to cancer.

The millions of people around the world who loved What If? still have questions, and those questions are getting stranger. Thank goodness xkcd creator Randall Munroe is here to help. Planning to ride a fire pole from the Moon back to Earth? The hardest part is sticking the landing. Hoping to cool the atmosphere by opening everyone’s freezer door at the same time? Maybe it’s time for a brief introduction to thermodynamics. Want to know what would happen if you rode a helicopter blade, made a lava lamp out of lava, or jumped on an erupting geyser? Okay, if you insist.

So you’ve fallen in love with space and now you want to see it for yourself, huh? You want to witness the birth of a star, or visit the black hole at the center of our galaxy? You want to know if there are aliens out there, or how to travel through a wormhole? You want the wonders of the universe revealed before your very eyes? Well stop, because all that will probably kill you.

Sweating may be one of our weirdest biological functions, but it’s also one of our most vital and least understood. In The Joy of Sweat, Sarah Everts delves into its role in the body - and in human history. Everts’ entertaining investigation takes listeners around the world - from Moscow, where she participates in a dating event in which people sniff sweat in search of love, to New Jersey, where companies hire trained armpit sniffers to assess the efficacy of their anti-sweat products. Along the way, Everts traces humanity’s long quest to control sweat.

Stephen Hawking not only unraveled some of the universe's greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet - including climate change, the threat of nuclear war, and the development of artificial intelligence - he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history.

An astonishing new science called neuroplasticity is overthrowing the centuries-old notion that the human brain is immutable. Psychiatrist and psychoanalyst, Norman Doidge, MD, traveled the country to meet both the brilliant scientists championing neuroplasticity and the people whose lives they've transformed - people whose mental limitations or brain damage were seen as unalterable.

Why do minds exist? How did mud and stone develop into beings that can experience longing, regret, love, and compassion - beings that are aware of their own experience? Until recently, science offered few answers to these existential questions. Journey of the Mind is the first book to offer a unified account of the mind that explains how consciousness, language, the Self, and civilization emerged incrementally out of chaos.

The answers to these questions are right behind our eyes. The greatest technology we have ever discovered on our planet is the three-pound organ carried in the vault of the skull. This book is not simply about what the brain is; it is about what it does. The magic of the brain is not found in the parts it’s made of but in the way those parts unceasingly reweave themselves in an electric, living fabric.

In The Ice at the End of the World, Jon Gertner explains how Greenland has evolved from one of earth’s last frontiers to its largest scientific laboratory. The history of Greenland’s ice begins with the explorers who arrived here at the turn of the 20th century. Their original goal was to conquer Greenland’s seemingly infinite interior. Yet their efforts eventually gave way to scientists who built lonely encampments out on the ice and began drilling - one mile, two miles down.Their aim was to pull up ice cores that could reveal the deepest mysteries of earth’s past.

You wake up and feel a tickle in your throat. Your head hurts. You’re mildly annoyed as you get the kids ready for school and dress for work yourself. Meanwhile, an epic war is being fought, just below your skin. Millions are fighting and dying for you to be able to complain as you head out the door. So what, exactly, is your immune system? In Immune, Philipp Dettmer, the brains behind the most popular science channel on YouTube, takes listeners on a journey through the fortress of the human body and its defenses.

Sparked by a controversial debate in February 2014, Bill Nye has set off on an energetic campaign to spread awareness of evolution and the powerful way it shapes our lives. In Undeniable: Evolution and the Science of Creation, he explains why race does not really exist; evaluates the true promise and peril of genetically modified food; reveals how new species are born, in a dog kennel and in a London subway; takes a stroll through 4.5 billion years of time; and explores the new search for alien life, including aliens right here on Earth.

Emily Craig has been a witness to history, helping to seek justice for thousands of murder victims, both famous and unknown. It’s a personal story that you won’t soon forget. Emily first became intrigued by forensics work when, as a respected medical illustrator, she was called in by the local police to create a model of a murder victim’s face. Her fascination with that case led to a dramatic midlife career change: She would go back to school to become a forensic anthropologist - and one of the most respected and best-known “bone hunters” in the nation.

We live on a planet alive with song, music, and speech. David Haskell explores how these wonders came to be. In rain forests shimmering with insect sound and swamps pulsing with frog calls we learn about evolution’s creative powers. From birds in the Rocky Mountains and on the streets of Paris, we discover how animals learn their songs and adapt to new environments. Below the waves, we hear our kinship to beings as different as snapping shrimp, toadfish, and whales.

The history of Iceland began 1,200 years ago, when a frustrated Viking captain and his useless navigator ran aground in the middle of the North Atlantic.

Instead, it became a nation whose diplomats and musicians, sailors and soldiers, volcanoes and flowers, quietly altered the globe forever. How Iceland Changed the World takes readers on a tour of history, showing them how Iceland played a pivotal role in events as diverse as the French Revolution, the Moon Landing, and the foundation of Israel.

Many of us know that the Moon pulls on our oceans, driving the tides, but did you know that it smells like gunpowder? Or that it was essential to the development of science and religion? Acclaimed journalist Rebecca Boyle takes listeners on a dazzling tour to reveal the intimate role that our 4.51-billion-year-old companion has played in our biological and cultural evolution.

Author Kevin Grange—former paramedic and park ranger at Yellowstone and Grand Teton—comes face-to-face with North America’s most fearsome predator, Ursus Arctos. His quest takes him from his home in the Tetons to an eerie, mist-shrouded island of gigantic bruins; from the Bear Center at Washington State University—where scientists believe the secrets of hibernation might help treat diabetes, heart disease, and obesity in humans—to the dark underbelly of for-profit wildlife parks, illegal animal trade and black markets hawking bear bile.

Rosemary and Peter Grant and those assisting them have spend 20 years on Daphne Major, an island in the Galapagos, studying natural selection. They recognize each individual bird on the island, when there are 400 at the time of the author's visit or when there are over a thousand. They have observed about 20 generations of finches - continuously.Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself.
