Punctuated Equilibrium
by Stephen Jay Gould"Punctuated Equilibrium" holds that the great majority of species originate in geological moments (punctuations) and persist in stasis. The idea was hotly debated because it forced biologists to rethink entrenched ideas about evolutionary patterns and processes. But as Gould shows here in his typically exhaustive coverage, the idea has become the foundation of a new view of hierarchical selection and macro-evolution.

Puppy Kindergarten: The New Science of Raising a Great Dog
by Brian Hare Vanessa WoodsThe New York Times bestselling authors of The Genius of Dogs take us into their &“Puppy Kindergarten&” at Duke University, a center to study how puppies develop, to show us what goes in to raising a great dog.Don&’t miss Brian Hare and Vanessa Woods in Netflix&’s film Inside the Mind of a Dog! &“A firehose of knowledge suffused with levity and charm.&”—Alexandra Horowitz, author of Inside of a DogWhat does it take to raise a great dog? This was the question that husband-and-wife team Brian Hare and Vanessa Woods hoped to answer when they enrolled one hundred and one puppies in the Duke Puppy Kindergarten. With the help of a retired service dog named Congo, Brian, Vanessa, and their team set out to understand the secrets of the puppy mind: What factors might predict whether a puppy will grow up to change someone&’s life?Never has cuteness been so cutting edge. Applying the same games that psychologists use when exploring the development of young children, Hare and Woods uncover what happens in a puppy&’s mind during their final stage of rapid brain development. Follow the adventures of Arthur, who makes friends with toy dinosaurs; Wisdom, the puppy genius; and Ying, who fails at cognitive games that even pigeons usually pass with flying colors. Along the way, learn about when puppies finally start to retain memories for longer than just a few seconds, or when they finally develop some self-control.Raising dozens of puppies on a college campus means you get pretty good at answering big questions, such as: When do puppies sleep through the night? How do you stop them from eating poop? How can we help our puppies grow up to be the best dogs they can possibly be? Whether you are a new puppy parent or a perennial puppy lover, Puppy Kindergarten will answer every question you&’ve ever had about puppies—and some you never thought to ask.
Pura Química
by Adela Muñoz PáezUn ingenioso recorrido por las partículas que nos han cambiado la vida. Antes de que el bótox revolucionara la estética fue utilizado como arma de guerra. Las pinturas rupestres se hicieron con el mismo compuesto básico que las actuales cremas solares. Las luces de Navidad emiten un mensaje similar al de los machos de las luciérnagas. El arsénico fue usado primero en las paredes de las casas acaudaladas que como artefacto mortal. Y ya en documentos sumerios aparecían referencias al té de sauce, en el que Bayer se fijaría para patentar la aspirina. Adela Muñoz Páez traza el camino entre pasado y presente a través de las partículas, átomos y moléculas que han configurado nuestro día a día. Con un estilo ameno, pero riguroso, acerca en esta serie de artículos la ciencia pura a lectores ávidos del más elemental de los conocimientos. «Los seres humanos somos capaces de pensar, sentir, vivir, gracias a una infinidad de reacciones químicas que tienen lugar en nuestros cuerpos. Por eso no tiene ningún sentido hablar de lo natural frente a lo químico, porque nosotros, como todos los seres vivos, somos química, pura química».
Pure Human: The Hidden Truth of Our Divinity, Power, and Destiny
by Gregg BradenIn an age where technologies such as AI threaten to supplant human intelligence, an award-winning scientist offers a radical new view of our innate human technology and what we're truly capable of.There are rare moments in time when we make choices that irreversibly change the world, and our lives, forever. Today is one of those moments.Scientists, engineers and philosophers alike warn us that without a radical shift in our thinking, we are on track to be the last generation of pure humans that the world will know. Within a single generation we will devolve into a hybrid species of synthetic bodies, Artificial Intelligence (AI), and computer chips that limit our ability to think, to love, and to adapt to the conditions of the emerging world in a healthy way. In doing so we will also lose our capacity for emotion, empathy, intimacy, and forgiveness—the very qualities that we value and cherish in our humanness.The question that we face is simple: Do we love ourselves enough to preserve the gift of our humanness? Our answer is based upon the way we&’ve been taught to think of ourselves.This book is a compelling journey of self-discovery that will catapult you beyond conventional thinking when it comes to your origins, your limits and, most importantly, the abilities that have been hidden from you for centuries, and the extraordinary potential that awaits as you embrace them.

Purification of Peptides in High-Complexity Arrays: A New Method for the Specific Surface Exchange and Purification of Entire Peptide Libraries
by Christopher SchirwitzChristopher Schirwitz's thesis focuses on improving the quality of in situ synthesized high-complexity peptide micro arrays. Micro arrays containing proteins or small protein fragments in the form of peptides have become of great interest in proteomic research. With the help of these microarrays a large number of potential target molecules can be screened for interaction with a probe in a short timeframe. However, protein and peptide micro arrays are still lagging behind oligonucleotide arrays in terms of density, quality and manufacturing costs. A new approach developed at the German Cancer Research Center (DKFZ) has improved the synthesis of high-density peptide arrays. The current technology is capable of producing arrays with up to 40,000 different peptides per square cm by means of micro particle-based solid phase peptide synthesis. However, in situ synthesis approaches bear a conceptual disadvantage: The quality of the peptides is dependent on the efficiency of the synthesis so that peptide fragments are present in the resulting array among the desired full-length peptides. In peptide-protein interaction studies such peptide fragments. The central achievement of this thesis is the development of a new method allowing for the fast one-step purification of entire arrays without loss of resolution or spatial information. Christopher Schirwitz's work has resulted in a number of publications in high ranking journals.
Purifying and Indexing Technology for Nucleic Acids-Based Next Generation Storage Medium (Springer Theses)
by Hansol ChoiThis book introduces novel purification technology for the complex oligonucleotide libraries. Since the concept of synthesizing oligonucleotides (oligos) has been proposed, research fields such as nucleic acid-based therapies (CRISPR-Cas9, DNA/RNA vaccines, RNAi), synthetic biology, protein engineering, and DNA-based data storage have bloomed. The COVID-19 pandemic underscores the potential of nucleic acid-based technologies, such as vaccines or diagnostics. As they emerge as the most promising weapons against the current pandemic, increasing need for highly accessible nucleic acid purification technologies is expected. To meet this demand, an oligo purification technology that can be applied to complex oligo libraries and can purify oligos with single-base resolution is developed. In addition, the purification technology can be applied to highly complex oligo libraries of different lengths, enabling the simultaneous purification of complex oligo libraries with different lengths. The proposed technology can be easily accessed by users and would help accelerate numerous research fields that utilize oligos as fundamental building blocks.

Purpose & Desire: What Makes Something "Alive" and Why Modern Darwinism Has Failed to Explain It
by J. Scott TurnerCan biology define life? “[An] ingenious mixture of science and philosophy. . . . highly thought-provoking.” —Kirkus Reviews (starred review)In this book a professor, biologist, and physiologist argues that modern Darwinism’s materialist and mechanistic biases have led to a scientific dead end, unable to define what life is—and only an openness to the qualities of purpose and desire will move the field forward.As Scott Turner contends: “To be scientists, we force ourselves into a Hobson’s choice on the matter: accept intentionality and purposefulness as real attributes of life, which disqualifies you as a scientist; or become a scientist and dismiss life’s distinctive quality from your thinking. I have come to believe that this choice actually stands in the way of our having a fully coherent theory of life.”Growing research shows that life’s most distinctive quality, shared by all living things, is purpose and desire: maintain homeostasis to sustain life. In Purpose and Desire, Turner draws on the work of Claude Bernard, a contemporary of Darwin revered among physiologists as the founder of experimental medicine, to build on Bernard’s “dangerous idea” of vitalism, which seeks to identify what makes “life” a unique phenomenon of nature. To further its quest to achieve a fuller understanding of life, Turner says, science must move beyond strictly accepted measures that consider only the mechanics of nature. A thoughtful appeal to widen our perspective of biology that is grounded in scientific evidence, Purpose and Desire helps us bridge the ideological evolutionary divide.“A must-read for everybody interested in the science of life and evolution . . . one of those rare science books which inquisitive laypeople will equally enjoy. Purpose and Desire will change the way you think of life.” —Washington Book Review“[A] beautifully written book, brimming with anecdotes and biological insights . . . will leave readers moved by Turner’s deep appreciation of life’s exquisiteness, its richness, and diversity . . . a provocative thesis, but one that is a wonderfully rich read, thought-provoking, and highly recommended.” —The Quarterly Review of Biology
Purpose: What Evolution and Human Nature Imply about the Meaning of Our Existence
by Samuel T. WilkinsonBy using principles from a variety of scientific disciplines, Yale Professor Samuel Wilkinson provides a framework for human evolution that reveals an overarching purpose to our existence. Generations have been taught that evolution implies there is no overarching purpose to our existence, that life has no fundamental meaning. We are merely the accumulation of tens of thousands of intricate molecular accidents. Some scientists take this logic one step further, suggesting that evolution is intrinsically atheistic and goes against the concept of God. But is this true? By integrating emerging principles from a variety of scientific disciplines—ranging from evolutionary biology to psychology—Yale Professor Samuel Wilkinson provides a framework of evolution that implies not only that there is an overarching purpose to our existence, but what this purpose is. With respect to our evolution, nature seems to have endowed us with competing dispositions, what Wilkinson calls the dual potential of human nature. We are pulled in different directions: selfishness and altruism, aggression and cooperation, lust and love. When we couple this with the observation that we possess a measure of free will, all this strongly implies there is a universal purpose to our existence. This purpose, at least one of them, is to choose between the good and evil impulses that nature has created within us. Our life is a test. This is a truth, as old as history it seems, that has been espoused by so many of the world&’s religions. From a certain framework, these aspects of human nature—including how evolution shaped us—are evidence for the existence of a God, not against it. Closely related to this is meaning. What is the meaning of life? Based on the scientific data, it would seem that one such meaning is to develop deep and abiding relationships. At least that is what most people report are the most meaningful aspects of their lives. This is a function of our evolution. It is how we were created.
Pursuing Power and Light: Technology and Physics from James Watt to Albert Einstein (Johns Hopkins Introductory Studies in the History of Science)
by Bruce J. HuntIn the nineteenth century, science and technology developed a close and continuing relationship. The most important advancements in physics—the science of energy and the theory of the electromagnetic field—were deeply rooted in the new technologies of the steam engine, the telegraph, and electric power and light. Bruce J. Hunt here explores how the leading technologies of the industrial age helped reshape modern physics.This period marked a watershed in how human beings exerted power over the world around them. Sweeping changes in manufacturing, transportation, and communications transformed the economy, society, and daily life in ways never before imagined. At the same time, physical scientists made great strides in the study of energy, atoms, and electromagnetism. Hunt shows how technology informed science and vice versa, examining the interaction between steam technology and the formulation of the laws of thermodynamics, for example, and that between telegraphy and the rise of electrical science.Hunt’s groundbreaking introduction to the history of physics points to the shift to atomic and quantum physics. It closes with a brief look at Albert Einstein’s work at the Swiss patent office and the part it played in his formulation of relativity theory. Hunt translates his often-demanding material into engaging and accessible language suitable for undergraduate students of the history of science and technology.
Pursuing Sustainability: OR/MS Applications in Sustainable Design, Manufacturing, Logistics, and Resource Management (International Series in Operations Research & Management Science #301)
by Vaidyanathan Jayaraman Yihsu Chen Chialin ChenThis handbook includes three parts, corresponding to the following three domains of OR/MS research related to sustainability: (i) Systems Design, Innovation, and Technology, (ii) Manufacturing, Logistics, and Transportation, and (iii) Sustainable Natural Resource Management. The first part of the handbook (Chapters 2-6) will focus on the creation and development of sustainable products, services, value chains, and organizations from a systems perspective. Key areas to be covered include Green Design & Innovation, Technology and Engineering Management, Sustainable Value Chain Systems, Sustainability Standards and Performance Evaluation, and Circular Economy and New Research Directions in Sustainability. The second part of the handbook (Chapters 7-11) will concentrate on the major operational and logistic issues faced by today’s industries in pursuing sustainability. Key areas to be covered include Remanufacturing, Reverse Logistics, Closed-Loop Supply Chains, Sustainable Transportation, and New Research Directions in Green Supply Chain Management. The third part of the proposed handbook (Chapters 12-16) will center on major sustainability issues in managing engineering infrastructure and natural resources. Key areas to be covered include Renewable Energy, Sustainable Water Resource, Biofuel Infrastructure, Natural Gas, and New Research Direction in Sustainable Resource Management.The handbook aims to bridge the three main OR/MS research domains in sustainability: “Systems Design, Innovation, and Technology,” “Manufacturing, Logistics, and Transportation,” and “Sustainable Natural Resource Management.” Traditionally, these domains are treated separately in the OR/MS literature. By combining the three domains, the handbook will provide a more holistic treatment of MS/OR methodologies to address critical sustainability issues faced by today’s society. Unlike most existing handbooks which only focus on current OR/MS research in sustainability within a domain, this handbook will include a concluding chapter in each of the three parts to discuss and identify potential future research directions in each of the three main domains.
Pursuing the Unity of Science: Ideology and Scientific Practice from the Great War to the Cold War (Science, Technology and Culture, 1700-1945)
by Harmke Kamminga Geert SomsenFrom 1918 to the late 1940s, a host of influential scientists and intellectuals in Europe and North America were engaged in a number of far-reaching unity of science projects. In this period of deep social and political divisions, scientists collaborated to unify sciences across disciplinary boundaries and to set up the international scientific community as a model for global political co-operation. They strove to align scientific and social objectives through rational planning and to promote unified science as the driving force of human civilization and progress. This volume explores the unity of science movement, providing a synthetic view of its pursuits and placing it in its historical context as a scientific and political force. Through a coherent set of original case studies looking at the significance of various projects and strategies of unification, the book highlights the great variety of manifestations of this endeavour. These range from unifying nuclear physics to the evolutionary synthesis, and from the democratization of scientific planning to the utopianism of H.G. Wells's world state. At the same time, the collection brings out the substantive links between these different pursuits, especially in the form of interconnected networks of unification and the alignment of objectives among them. Notably, it shows that opposition to fascism, using the instrument of unified science, became the most urgent common goal in the 1930s and 1940s. In addressing these issues, the book makes visible important historical developments, showing how scientists participated in, and actively helped to create, an interwar ideology of unification, and bringing to light the cultural and political significance of this enterprise.
