Looking at Ribozymes: Biology of Catalytic RNA
by Benoît MasquidaBehind the neologism “ribozymes” lies a family of fascinating molecules, ribo-enzymes, which have been relatively little studied. These catalytically active RNAs are found in all strata of life, from viruses to the human genome. At the end of the 1970s, the discovery of a catalytic RNA nestled in an intron, followed by another involved in the maturation of transfer RNAs, led to the discovery of new ribozymes and the transition from a strictly “proteocentric” vision, inherited from the dogma of molecular biology, to a more “nucleocentric” one. Since then, a variety of ribozymes have been identified in genomes, where their functions often remain mysterious. Looking at Ribozymes traces the discovery of these molecules and presents a picture of their functional diversity, catalytic mechanisms and distribution within the tree of life.

Looking for a Few Good Males: Female Choice in Evolutionary Biology (Animals, History, Culture)
by Erika L. Milam2010 Outstanding Academic Title, Choice MagazineWhy do female animals select certain mates, and how do scientists determine the answer? In considering these questions, Erika Lorraine Milam explores the fascinating patterns of experiment and interpretation that emerged as twentieth-century researchers studied sexual selection and female choice. Approaching the topic from both biological and animal-studies perspectives, Milam not only presents a broad history of sexual selection—from Darwin to sociobiology—but also analyzes the animal-human continuum from the perspectives of sex, evolution, and behavior. She asks how social and cultural assumptions influence human-animal research and wonders about the implications of gender on scientific outcomes. Although female choice appears to be a straightforward theoretical concept, the study of sexual selection has been anything but simple. Scientists in the early twentieth century investigated female choice in animals but did so with human social and sexual behavior as their ultimate objective. By the 1940s, evolutionary biologists and population geneticists shifted their focus, studying instead how evolution affected natural animal populations. Two decades later, organismal biologists once again redefined the investigation of sexual selection as sociobiology came to dominate the discipline.Outlining the ever-changing history of this field of study, Milam uncovers lost mid-century research programs and finds that the discipline did not languish in the decades between Darwin’s theory of sexual selection and sociobiology, as observers commonly believed. Rather, population geneticists, ethologists, and organismal biologists alike continued to investigate this important theory throughout the twentieth century.

Looking for Spinoza: Joy, Sorrow, and the Feeling Brain
by Antonio DamasioA famed neuroscientist explores the emotions that make life worth living in &“clear, accessible, and at times eloquent prose&” (San Francisco Chronicle). In the seventeenth century, the philosopher Spinoza examined the role emotion played in human survival and culture. Yet, the neurobiological roots of joy and sorrow remained a mystery. Today, we spend countless resources doctoring our feelings with alcohol, prescription drugs, health clubs, therapy, vacation retreats, and other sorts of consumption; yet the inner workings of our minds—what feelings are, how they work, and what they mean—are still largely an unexplored frontier. Here, bestselling author and distinguished scientist Antonio Demasio concludes the groundbreaking trilogy he began with Descartes&’ Error by drawing on his innovative research and experience with neurological patients to examine the cerebral processes of human emotion. With scientific expertise and &“a flair for writing,&” he navigates the neurology of feelings (The New York Review of Books). &“Damasio has the rare talent of rendering science intelligible while also being gifted in philosophy, literature and wit.&” —Margaret Jacob, Los Angeles Times &“Exceptionally engaging and profoundly gratifying . . . Achieves a unique combination of scientific exposition, historical discovery and deep personal statement regarding the human condition.&” —Nature &“Damasio . . . succeeds in making the latest brain research accessible to the general reader, while his passionate Spinozist reflections make that data relevant to everyday life.&” —Publishers Weekly
Looking Forward: Prediction and Uncertainty in Modern America
by Jamie L. PietruskaIn the decades after the Civil War, the world experienced monumental changes in industry, trade, and governance. As Americans faced this uncertain future, public debate sprang up over the accuracy and value of predictions, asking whether it was possible to look into the future with any degree of certainty. In Looking Forward, Jamie L. Pietruska uncovers a culture of prediction in the modern era, where forecasts became commonplace as crop forecasters, “weather prophets,” business forecasters, utopian novelists, and fortune-tellers produced and sold their visions of the future. Private and government forecasters competed for authority—as well as for an audience—and a single prediction could make or break a forecaster’s reputation. Pietruska argues that this late nineteenth-century quest for future certainty had an especially ironic consequence: it led Americans to accept uncertainty as an inescapable part of both forecasting and twentieth-century economic and cultural life. Drawing together histories of science, technology, capitalism, environment, and culture, Looking Forward explores how forecasts functioned as new forms of knowledge and risk management tools that sometimes mitigated, but at other times exacerbated, the very uncertainties they were designed to conquer. Ultimately Pietruska shows how Americans came to understand the future itself as predictable, yet still uncertain.
Looking Inside Jets: An Introduction to Jet Substructure and Boosted-object Phenomenology (Lecture Notes in Physics #958)
by Simone Marzani Gregory Soyez Michael SpannowskyThis concise primer reviews the latest developments in the field of jets. Jets are collinear sprays of hadrons produced in very high-energy collisions, e.g. at the LHC or at a future hadron collider. They are essential to and ubiquitous in experimental analyses, making their study crucial. At present LHC energies and beyond, massive particles around the electroweak scale are frequently produced with transverse momenta that are much larger than their mass, i.e., boosted. The decay products of such boosted massive objects tend to occupy only a relatively small and confined area of the detector and are observed as a single jet. Jets hence arise from many different sources and it is important to be able to distinguish the rare events with boosted resonances from the large backgrounds originating from Quantum Chromodynamics (QCD). This requires familiarity with the internal properties of jets, such as their different radiation patterns, a field broadly known as jet substructure. This set of notes begins by providing a phenomenological motivation, explaining why the study of jets and their substructure is of particular importance for the current and future program of the LHC, followed by a brief but insightful introduction to QCD and to hadron-collider phenomenology. The next section introduces jets as complex objects constructed from a sequential recombination algorithm. In this context some experimental aspects are also reviewed. Since jet substructure calculations are multi-scale problems that call for all-order treatments (resummations), the bases of such calculations are discussed for simple jet quantities. With these QCD and jet physics ingredients in hand, readers can then dig into jet substructure itself. Accordingly, these notes first highlight the main concepts behind substructure techniques and introduce a list of the main jet substructure tools that have been used over the past decade. Analytic calculations are then provided for several families of tools, the goal being to identify their key characteristics. In closing, the book provides an overview of LHC searches and measurements where jet substructure techniques are used, reviews the main take-home messages, and outlines future perspectives.
Looking Inside the Brain: The Power of Neuroimaging
by Denis Le BihanThe remarkable story of how today's brain scanning techniques were developed, told by one of the field's pioneersIt is now possible to witness human brain activity while we are talking, reading, or thinking, thanks to revolutionary neuroimaging techniques like magnetic resonance imaging (MRI). These groundbreaking advances have opened infinite fields of investigation—into such areas as musical perception, brain development in utero, and faulty brain connections leading to psychiatric disorders—and have raised unprecedented ethical issues. In Looking Inside the Brain, one of the leading pioneers of the field, Denis Le Bihan, offers an engaging account of the sophisticated interdisciplinary research in physics, neuroscience, and medicine that have led to the remarkable neuroimaging methods that give us a detailed look into the human brain.Introducing neurological anatomy and physiology, Le Bihan walks readers through the historical evolution of imaging technology—from the x-ray and CT scan to the PET scan and MRI—and he explains how neuroimaging uncovers afflictions like stroke or cancer and the workings of higher-order brain activities, such as language skills. Le Bihan also takes readers on a behind-the-scenes journey through NeuroSpin, his state-of-the-art neuroimaging laboratory, and goes over the cutting-edge scanning devices currently being developed. Considering what we see when we look at brain images, Le Bihan weighs what might be revealed about our thoughts and unconscious, and discusses how far this technology might go in the future.Beautifully illustrated in color, Looking Inside the Brain presents the trailblazing story of the scanning techniques that provide keys to previously unimagined knowledge of our brains and our selves.

by Matthew CappucciAn energetic and electrifying narrative about all things weather—by one of today's rising meteorological stars.Get in—we&’re going storm-chasing! Imagine a very cool weather nerd has just pulled up to you and yelled this out the window of his custom-built armored storm-chasing truck. The wind is whipping around, he&’s munching on Wawa, it&’s all very chaotic—yet as you look into his grinning face, you feel the greatest surge of adrenaline you have ever felt in your life. Hallelujah: your cavalry is here! Welcome to the brilliance of Looking Up, the lively new book from rising meterology star Matthew Cappucci. He&’s a meteorologist for The Washington Post, and you might think of him as Doogie Howser meets Bill Paxton from Twister, with a dash of Leonardo DiCaprio from Catch Me If You Can. A self-proclaimed weather nerd, at the age of fourteen he talked his way into delivering a presentation on waterspouts at the American Meteorological Society's annual broadcast conference by fudging his age on the application and created his own major on weather science while an undergrad at Harvard. Combining reportage and accessible science with personal storytelling and infectious enthusiasm, Looking Up is a riveting ride through the state of our weather and a touching story about parents and mentors helping a budding scientist achieve his improbable dreams. Throughout, readers get a tutorial on the basics of weather science and the impact of the climate. As our country&’s leaders sound the alarm on climate change, few people have as close a view to how serious the situation actually is than those whose job is to follow the weather, which is the daily dose of climate we interact with and experience every day. The weather affects every aspect of our lives (even our art) as well as our future. The way we think about it requires a whole-life overhaul. Rain or shine, tropical storm or twister, Cappucci is here to help us begin the process. So get in his storm-chasing truck already, will ya?
Loonshots: How to Nurture the Crazy Ideas That Win Wars, Cure Diseases, and Transform Industries
by Safi Bahcall* Next Big Idea Club Selection *Washington Post's "10 Leadership Books to Watch for in 2019," Adam Grant's "19 New Leadership Books to Read in 2019," Inc.com's "10 Business Books You Need to Read in 2019," Business Insider's "14 Books Everyone Will Be Reading in 2019"“This book has everything: new ideas, bold insights, entertaining history and convincing analysis. Not to be missed by anyone who wants to understand how ideas change the world.” —Daniel Kahneman, winner of the Nobel Prize and author of Thinking, Fast and Slow What do James Bond and Lipitor have in common? What can we learn about human nature and world history from a glass of water?In Loonshots, physicist and entrepreneur Safi Bahcall reveals a surprising new way of thinking about the mysteries of group behavior that challenges everything we thought we knew about nurturing radical breakthroughs.Drawing on the science of phase transitions, Bahcall shows why teams, companies, or any group with a mission will suddenly change from embracing wild new ideas to rigidly rejecting them, just as flowing water will suddenly change into brittle ice. Mountains of print have been written about culture. Loonshots identifies the small shifts in structure that control this transition, the same way that temperature controls the change from water to ice.Using examples that range from the spread of fires in forests to the hunt for terrorists online, and stories of thieves and geniuses and kings, Bahcall shows how this new kind of science helps us understand the behavior of companies and the fate of empires. Loonshots distills these insights into lessons for creatives, entrepreneurs, and visionaries everywhere.Over the past decade, researchers have been applying the tools and techniques of phase transitions to understand how birds flock, fish swim, brains work, people vote, criminals behave, ideas spread, diseases erupt, and ecosystems collapse. If twentieth-century science was shaped by the search for fundamental laws, like quantum mechanics and gravity, the twenty-first will be shaped by this new kind of science. Loonshots is the first to apply these tools to help all of us unlock our potential to create and nurture the crazy ideas that change the world.

The Loop (The Loop #1)
by Ben Oliver"A script-ready story with blockbuster potential." -- Kirkus (Starred Review)Life inside The Loop--the futuristic death row for teens under eighteen--is one long repetitive purgatory. But when news of the encroaching chaos in the outside world reaches the inmates and disorder begins to strike, the prison becomes the least of their worries. Perfect for fans of The Maze Runner and The Fifth Wave.It's Luka Kane's 16th birthday and he's been inside The Loop for over two years. Every inmate is serving a death sentence with the option to push back their execution date by six months if they opt into "Delays," scientific and medical experiments for the benefit of the elite in the outside world.But rumors of a war on the outside are spreading amongst the inmates, and before they know it, their tortuous routine becomes disrupted. The government-issued rain stops falling. Strange things are happening to the guards. And it's not long until the inmates are left alone inside the prison.Were the chains that shackled Luka to his cell the only instruments left to keep him safe? In a thrilling shift, he must overcome fellow prisoners hell-bent on killing him, the warden losing her mind, the rabid rats in the train tunnels, and a population turned into murderous monsters to try and break out of The Loop, save his family, and discover who is responsible for the chaos that has been inflicted upon the world.
The Loop: How Technology Is Creating a World Without Choices and How to Fight Back
by Jacob WardThis eye-opening narrative journey into the rapidly changing world of artificial intelligence reveals the dangerous ways AI is exploiting the unconscious habits of our minds, and the real threat it poses to humanity: "The best book I have ever read about AI" (New York Times bestselling author Roger McNamee). Artificial intelligence is going to change the world as we know it. But the real danger isn't some robot that's going to enslave us: It's our own brain. Our brains are constantly making decisions using shortcuts, biases, and hidden processes—and we're using those same techniques to create technology that makes choices for us. In The Loop, award-winning science journalist Jacob Ward reveals how we are poised to build all of our worst instincts into our AIs, creating a narrow loop where each generation has fewer, predetermined, and even dangerous choices. Taking us on a world tour of the ongoing, real-world experiment of artificial intelligence, The Loop illuminates the dangers of writing dangerous human habits into our machines. From a biometric surveillance state in India that tracks the movements of over a billion people, to a social media control system in China that punishes deviant friendships, to the risky multiple-choice simplicity of automated military action, Ward travels the world speaking with top experts confronting the perils of their research. Each stop reveals how the most obvious patterns in our behavior—patterns an algorithm will use to make decisions about what's best for us—are not the ones we want to perpetuate. Just as politics, marketing, and finance have all exploited the weaknesses of our human programming, artificial intelligence is poised to use the patterns of our lives to manipulate us. The Loop is call to look at ourselves more clearly—our most creative ideas, our most destructive impulses, the ways we help and hurt one another-so we can put only the best parts of ourselves into the thinking machines we create.

Records show it has been cultivated in China for over 2000 years. From this beginning, loquat has spread to more than 30 countries around the world. Grown in various regions of Asia, the Mediterranean and across the Americas, loquats suit both temperate and subtropical areas, sharing the same environmental conditions as citrus. Loquat is an increasingly commercial crop in some Asian and European countries with a good amount of international trade. Recent research has focused on improving crop yields and quality. Over 100 different varieties have been developed to meet both growers' and consumers' demands. These developments have contributed to a better understanding of the crop environment, plant growth and physiology of tree and fruit development with implications for both breeding and cultivation. This book is to be the first to provide a comprehensive coverage of the history, physiology, culture and marketing of loquat throughout the world.

The Lorax
by Dr SeussLong before "going green" was mainstream, Dr. Seuss's Lorax spoke for the trees and warned of the dangers of disrespecting the environment. In this cautionary rhyming tale, we learn of the Once-ler, who came across a valley of Truffula Trees and Brown Bar-ba-loots, and how his harvesting of the tufted trees changed the landscape forever. With the release of the blockbuster film version, the Lorax and his classic tale have educated a new generation of young readers not only about the importance of seeing the beauty in the world around us, but also about our responsibility to protect it.
Lord Esher: A Political Biography
by Peter FraserAlthough wielding huge influence in late Victorian and Edwardian political life, Reginald Baliol Brett (1852 1930), the second Lord Esher was, an enigma to his contemporaries and still remains a puzzle to historians.At the heart of British and Imperial political affairs for several decades, Esher sat in both Houses of Parliament, was a high ranking civil servant, friend and confidential advisor to three Sovereigns and four Prime Ministers (of differing political hues) and yet refused high office offered by both Liberals and Conservatives. Yet his behind-the-scenes influence through his range of friends in high places gave him unmatched, some thought undemocratic, power. Despite his lack of military service he was instrumental through his work on the Committee for Imperial Defence (CID) and its Secretarial for the wholesale reorganisation of the Armed Forces. It could be said that Esher, with his grasp of power without responsibility, was a unique phenomenon in British history.The Author, while compiling this fascinating study, drew on Cabinet and CID files, the Royal Archives and the papers of the Esher, Balfour, Asquith and Lloyd George estates. The result is a brilliant readable yet scholarly addition to British political bibliography.
Lords of the Harvest: Biotech, Big Money, and the Future of Food
by Daniel CharlesBiotech companies are creating designer crops with strange powers-from cholesterol-reducing soybeans to tobacco plants that act as solar-powered pharmaceutical factories. They promise great benefits: better health for consumers and more productive agriculture. But the vision has a dark side. In Lords of the Harvest, Daniel Charles tells the real story behind "Frankenstein foods"-the story you won't hear from the biotech companies or their fiercest opponents. He reveals for the first time the cutthroat scientific competition and backroom business deals that led to the first genetically engineered foods. And he exposes the secrets of campaigns on both sides of the Atlantic aimed at bringing down the biotech industry. A riveting tale of boundless ambition, political intrigue, and the quest for knowledge, Lords of the Harvest is ultimately a story of idealism and conflicting dreams about the shape of a better world.
Lorentz Symmetry Breaking—Classical and Quantum Aspects (SpringerBriefs in Physics)
by Tiago Mariz Jose Roberto Nascimento Albert PetrovThis book presents a review of various issues related to Lorentz symmetry breaking. Explicitly, we consider (i) motivations for introducing Lorentz symmetry breaking, (ii) classical aspects of Lorentz-breaking field theory models including typical forms of Lorentz-breaking additive terms, wave propagation in Lorentz-breaking theories, and mechanisms for breaking the Lorentz symmetry; (iii) quantum corrections in Lorentz-breaking theories, especially the possibilities for perturbation generating the most interesting Lorentz-breaking terms; (iv) correspondence between non-commutative field theories and Lorentz symmetry breaking; (v) supersymmetric Lorentz-breaking theories; and (vi) Lorentz symmetry breaking in a curved space-time. We close the book with the review of experimental studies of Lorentz symmetry breaking. The importance and relevance of these topics are explained, first, by studies of limits of applicability of the Lorentz symmetry, second, by searches of the possible extensions of the standard model, including the Lorentz-breaking ones, and need to study their properties, third, by the relation between Lorentz symmetry breaking with string theory, fourth, by the problem of formulating a consistent quantum gravity theory, so that various modified gravity models are to be examined.
