50,000 years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species. Yet something about our species separated it from the pack, and led to its survival while the rest became extinct. So just what was it that allowed Homo sapiens to become Masters of the Planet?

In recent years, neuroscientists have uncovered the countless ways our brain trips us up in day-to-day life, from its propensity toward irrational thought to how our intuitions deceive us. The latest research on sleep, however, points in the opposite direction. Where old wives tales have long advised to "sleep on a problem," today scientists are discovering the truth behind these folk sayings, and how the busy brain radically improves our minds through sleep and dreams. In The Secret World of Sleep , neuroscientist Penny Lewis explores the latest research into the nighttime brain to understand the real benefits of sleep. She shows how, while our body rests, the brain practices tasks it learned during the day, replays traumatic events to mollify them, and forges connections between distant concepts. By understanding the roles that the nocturnal brain plays in our waking life, we can improve the relationship between the two, and even boost creativity and become smarter. This is a fascinating exploration of one of the most surprising corners of neuroscience that shows how science may be able to harness the power of sleep to improve learning, health, and more.

Few of us will ever get to Antarctica. The bitter cold and three months a year without sunlight makes the sixth continent virtually uninhabitable for humans. Yet marine biologist James B. McClintock has spent three decades studying the frozen land in order to understand better the world that lies beneath it. In this luminous and closely observed account, one of the world's leading experts on Antarctica introduces the reader to this fascinating world-the extraordinary wildlife that persists despite the harsh conditions and the way each of the pieces fit into the puzzle of the intricate environment: from single-celled organisms to baleen whales, with leopard seals, penguins, 50-foot algae, sea spiders, coral, and multicolored sea stars, in between. Now, as temperatures rise, the fragile ecosystem is under attack. Adélie penguins that have successfully nested on Antarctic islands for several hundred years have been nearly wiped out. King crabs that used to populate the deep seafloor are moving into shallower waters, disturbing the set order of life there. Lost Antarctica is an appeal to understand and appreciate the wondrous place at the bottom of the world that we are on the brink of losing.

In this groundbreaking look at the evolution of our brains, eminent neuroscientists Gary Lynch and Richard Granger uncover the mysteries of the outsize intelligence of our ancestors, who had bigger brains than humans living today. Weaving together history, science, and the latest theories of artificial intelligence, Lynch and Granger demystify the complexities of our brains, and show us how our memory, cognition, and intelligence actually function, as well as what mechanisms in the brain can potentially be enhanced, improving on the current design. Author of The Emotional Brain, Joseph LeDoux praised it as "provocative and fascinating," and, writing in the New Scientist, Willian Calvin called it "a popular account of how brains enlarge, in both evolutionary and developmental terms" and "a much needed book."

Called "one of our best science popularizers" by Publishers Weekly, Amir D. Aczel tackles the cause of one of last century's most destructive events--the scientific discovery of nuclear power. Drawing on his rich storytelling skills, Aczel presents the fascinating and suspenseful story of the scientists who first uncovered the potential of uranium. Uranium Wars takes the reader on a whirlwind tour of 1920s Europe where the scientific elite of the day were embroiled in a fierce rivalry to achieve nuclear fission. Leading us to an understanding of both the processes that take place inside a uranium nucleus and its destructive power are the brilliant men and women at the heart of the race--mammoth figures such as Marie Curie, Enrico Fermi, and Lise Meitner. Enmeshed in the story of scientific intrigue is the complex and ongoing story of uranium itself, which Aczel presents as a dynamic, dual natured force, capable of providing both abundant usable energy and generating unfathomable destructive power. From the nuclear programs in the Middle East to plans for nuclear reactors at home, the element uranium is never far from today's headlines.

Every time we download music, take a flight across the Atlantic or talk on our cell phones, we are relying on great mathematical inventions. In The Number Mysteries, one of our generation's foremost mathematicians Marcus du Sautoy offers a playful and accessible examination of numbers and how, despite efforts of the greatest minds, the most fundamental puzzles of nature remain unsolved. Du Sautoy tells about the quest to predict the future-from the flight of asteroids to an impending storm, from bending a ball like Beckham to forecasting population growth. He brings to life the beauty behind five mathematical puzzles that have contributed to our understanding of the world around us and have helped develop the technology to cope with it. With loads of games to play and puzzles to solve, this is a math book for everyone.
