In captivity, octopuses have been known to identify individual human keepers, raid neighboring tanks for food, turn off lightbulbs by spouting jets of water, plug drains, and make daring escapes. How is it that a creature with such gifts evolved through an evolutionary lineage so radically distant from our own? What does it mean that evolution built minds not once but at least twice? The octopus is the closest we will come to meeting an intelligent alien. What can we learn from the encounter?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. Tracking the mind’s fitful development, Godfrey-Smith shows how unruly clumps of seaborne cells began living together and became capable of sensing, acting, and signaling. As these primitive organisms became more entangled with others, they grew more complicated. The first nervous systems evolved, probably in ancient relatives of jellyfish; later on, the cephalopods, which began as inconspicuous mollusks, abandoned their shells and rose above the ocean floor, searching for prey and acquiring the greater intelligence needed to do so. Taking an independent route, mammals and birds later began their own evolutionary journeys.But what kind of intelligence do cephalopods possess? Drawing on the latest scientific research and his own scuba-diving adventures, Godfrey-Smith probes the many mysteries that surround the lineage. How did the octopus, a solitary creature with little social life, become so smart? What is it like to have eight tentacles that are so packed with neurons that they virtually “think for themselves”? What happens when some octopuses abandon their hermit-like ways and congregate, as they do in a unique location off the coast of Australia?By tracing the question of inner life back to its roots and comparing human beings with our most remarkable animal relatives, Godfrey-Smith casts crucial new light on the octopus mind—and on our own.

    Wild species, too, are escaping warming seas and desiccated lands, creeping, swimming, and flying in a mass exodus from their past habitats. News media presents this scrambling of the planet's migration patterns as unprecedented, provoking fears of the spread of disease and conflict and waves of anxiety across the Western world. On both sides of the Atlantic, experts issue alarmed predictions of millions of invading aliens, unstoppable as an advancing tsunami, and countries respond by electing anti-immigration leaders who slam closed borders that were historically porous.But the science and history of migration in animals, plants, and humans tell a different story. Far from being a disruptive behavior to be quelled at any cost, migration is an ancient and lifesaving response to environmental change, a biological imperative as necessary as breathing. Climate changes triggered the first human migrations out of Africa. Falling sea levels allowed our passage across the Bering Sea. Unhampered by barbed wire, migration allowed our ancestors to people the planet, catapulting us into the highest reaches of the Himalayan mountains and the most remote islands of the Pacific, creating and disseminating the biological, cultural, and social diversity that ecosystems and societies depend upon. In other words, migration is not the crisis--it is the solution.Conclusively tracking the history of misinformation from the 18th century through today's anti-immigration policies, The Next Great Migration makes the case for a future in which migration is not a source of fear, but of hope.

    This project turned into a quest to discover the secrets of the neighborhood’s flora and fauna, and yielded more than names and trivia: Johnson developed a relationship with his nonhuman neighbors.Johnson argues that learning to see the world afresh, like a child, shifts the way we think about nature: Instead of something distant and abstract, nature becomes real—all at once comical, annoying, and beautiful. This shift can add tremendous value to our lives, and it might just be the first step in saving the world.No matter where we live—city, country, oceanside, ormountains—there are wonders that we walk past every day. Unseen City widens the pinhole of our perspective by allowing us to view the world from the high-altitude eyes of a turkey vulture and the distinctly low-altitude eyes of a snail. The narrative allows us to eavesdrop on the comically frenetic life of a squirrel and peer deep into the past with a ginkgo biloba tree. Each of these organisms has something unique to tell us about our neighborhoods and, chapter by chapter, Unseen City takes us on a journey that is part nature lesson and part love letter to the world’s urban jungles. With the right perspective, a walk to the subway can be every bit as entrancing as a walk through a national park.

    This serves as practice for MCQ format examinations and as a basis for revision in combination with textbooks such as "Bailey & Love's Short Practice of Surgery". The book is based on "Bailey & Love" and its author was the senior editor for 25 years. The third edition reflects the revisions in the new 21st edition of "Bailey & Love". It contains a complete revision of questions and introduces over 250 new questions. Part 1 provides introductory exercises; part 2 uses standard MCQs following the arrangement of chapters in "Bailey & Love"; part 3 presents MCQs at random or in runs, as in examinations. This book should be of interest to clinical period undergraduate medical students; and postgraduate surgical trainees.

    Maybe it's made of silicon! Maybe it has wheels! Or maybe it doesn't. In The Equations of Life, biologist Charles S. Cockell makes the forceful argument that the laws of physics narrowly constrain how life can evolve, making evolution's outcomes predictable. If we were to find on a distant planet something very much like a lady bug eating something like an aphid, we shouldn't be surprised. The forms of life are guided by a limited set of rules, and as a result, there is a narrow set of solutions to the challenges of existence.A remarkable scientific contribution breathing new life into Darwin's theory of evolution, The Equations of Life makes a radical argument about what life can -- and can't -- be.

    

    And as outbreaks of COVID-19, Ebola, MERS, and Zika have demonstrated, we are woefully underprepared to deal with the fallout. So what can -- and must -- we do in order to protect ourselves from mankind's deadliest enemy?Drawing on the latest medical science, case studies, policy research, and hard-earned epidemiological lessons, Deadliest Enemy explores the resources and programs we need to develop if we are to keep ourselves safe from infectious disease. The authors show how we could wake up to a reality in which many antibiotics no longer cure, bioterror is a certainty, and the threat of a disastrous influenza or coronavirus pandemic looms ever larger. Only by understanding the challenges we face can we prevent the unthinkable from becoming the inevitable.Deadliest Enemy is high scientific drama, a chronicle of medical mystery and discovery, a reality check, and a practical plan of action.
