The Aliens Are Coming!: The Extraordinary Science Behind Our Search for Life in the Universe

by Ben Miller

Actor and bestselling science writer Ben Miller takes readers to the cutting edge of one of the greatest questions of all: Is there life beyond Earth? For millennia, we have looked up at the stars and wondered whether we are alone in the universe, but in the last few years—as our probes begin to escape the solar system, and our telescopes reveal thousands of Earthlike planets—scientists have taken huge leaps toward an answer. “Forget science fiction,” author Ben Miller writes. “We are living through one of the most extraordinary revolutions in the history of science: the emergent belief of a generation of physicists, biologists, and chemists that we are not alone.” The Aliens Are Coming! is a refreshingly clear, hugely entertaining guide to the search for alien life. Miller looks everywhere for insight, from the Big Bang’s sea of energy that somehow became living matter, to the equations that tell us Earth is not so rare, to the clues bacteria hold to how life started. And he makes the case that our growing understanding of life itself will help us predict whether it exists elsewhere, what it might look like, and when we might find it.

Aligning Climate Change and Sustainable Development Policies in Asia

by Hooman Farzaneh Eric Zusman Yeora Chae

This book provides policymakers, researchers, and other interested audiences with knowledge on how to quantify and integrate and advance co-benefits in their decisions. It begins with an introductory chapter that provides an overview of the concept of co-benefits. This followed by a section that details quantitative approaches to estimate co-benefits, particularly in cities. A third section presents a series of case studies from the energy sector in Northeast and Southeast Asia. A final section focuses on new perspectives on co-benefits from linking climate change with biodiversity, social justice, and through new models of co-innovation. The book is particularly timely as many countries in Asia seek to achieve objectives in the national climate policies and the Sustainable Development Goals (SDGs). The climate emergency poses an increasingly severe threat to the health and well-being of more than a billion people in Asia. Policymakers in the region have sought to curb this threat by adopting clean energy, energy efficiency, and other sectoral policies. In some cases, these policies can bring additional benefits beyond mitigating climate change. These so-called “co-benefits” --ranging from improved air quality to better health to socioeconomic equity--could not only offset the costs of climate mitigation but also make Asia’s development more sustainable. Yet all too frequently policymakers lack the analytical methods and practical experiences to incorporate co-benefits into their decisions. This has created difficulties in aligning climate and sustainable development policies in Asia.

Aligning the Energy Transition with the Sustainable Development Goals: Key Insights from Energy System Modelling (Lecture Notes in Energy #101)

The Alignment Problem: Machine Learning And Human Values

by Brian Christian

A jaw-dropping exploration of everything that goes wrong when we build AI systems and the movement to fix them. Today’s “machine-learning” systems, trained by data, are so effective that we’ve invited them to see and hear for us—and to make decisions on our behalf. But alarm bells are ringing. Recent years have seen an eruption of concern as the field of machine learning advances. When the systems we attempt to teach will not, in the end, do what we want or what we expect, ethical and potentially existential risks emerge. Researchers call this the alignment problem. Systems cull résumés until, years later, we discover that they have inherent gender biases. Algorithms decide bail and parole—and appear to assess Black and White defendants differently. We can no longer assume that our mortgage application, or even our medical tests, will be seen by human eyes. And as autonomous vehicles share our streets, we are increasingly putting our lives in their hands. The mathematical and computational models driving these changes range in complexity from something that can fit on a spreadsheet to a complex system that might credibly be called “artificial intelligence.” They are steadily replacing both human judgment and explicitly programmed software. In best-selling author Brian Christian’s riveting account, we meet the alignment problem’s “first-responders,” and learn their ambitious plan to solve it before our hands are completely off the wheel. In a masterful blend of history and on-the ground reporting, Christian traces the explosive growth in the field of machine learning and surveys its current, sprawling frontier. Readers encounter a discipline finding its legs amid exhilarating and sometimes terrifying progress. Whether they—and we—succeed or fail in solving the alignment problem will be a defining human story. The Alignment Problem offers an unflinching reckoning with humanity’s biases and blind spots, our own unstated assumptions and often contradictory goals. A dazzlingly interdisciplinary work, it takes a hard look not only at our technology but at our culture—and finds a story by turns harrowing and hopeful.

Alistair Grim's Odd Aquaticum (Alistair Grim #2)

by Greg Funaro

"Dive head-, feet-, or face-first into this delicious danger." -- Kirkus Reviews, starred review When Grubb, an orphan and runaway chimney sweep, entered the wondrous world of the Odditorium, his life changed forever. Apprenticed to the mechanical marvel's strange proprietor, Alistair Grim, Grubb unfortunately must settle into his new position on the lam, as all of England is convinced that Alistair Grim is a villain. Grim, however, has come up with a plan to expose the real villain: Prince Nightshade, a wicked necromancer who wants the Odditorium's power source for himself. With the evil prince hot on their trail, Grim, Grubb and the rest of the Odditorium's crew embark on a perilous adventure to find the legendary sword Excalibur: the only weapon capable of penetrating Nightshade's magical suit of armor. As expected, their quest turns out to be anything but ordinary. Not only can the Odditorium fly, but it can also swim! And so the crew battens down the hatches and sets off on an underwater voyage to the otherworldly realm of Avalon, home to Excalibur. Along the way, they must battle a banshee assassin, sea monsters, and a witch who seeks revenge on Alistair Grim for stealing her magical objects. But that's not all. Unbeknownst to Grubb and the others, their fate has been written in an ancient Avalonian prophecy-a prophecy that holds the key to a destiny not even Alistair Grim could have imagined.

The Alkali Metal Ions: Their Role for Life

by Astrid Sigel Helmut Sigel Roland K. O. Sigel

MILS-16 provides an up-to-date review of the impact of alkali metal ions on life. Their bioinorganic chemistry and analytical determination, the solid state structures of bio-ligand complexes and the properties of alkali metal ions in solution in the context of all kinds of biologically relevant ligands are covered, this includes proteins (enzymes) and nucleic acids (G-quadruplexes). Minerals containing sodium (Na+) and potassium (K+) are abundant in the Earth's crust, making Na+ and K+ easily available. In contrast, the alkali elements lithium (Li+), rubidium, and cesium are rare and the radioactive francium occurs only in traces. Since the intra- and extracellular, as well as the compartmental concentrations of Na+ and K+ differ significantly, homeostasis and active transport of these ions are important; this involves transporters/carriers and pore-forming ion channel proteins. Systems like Na+/K+-ATPases, H+/K+-ATPases or Na+/H+ antiporters are thoroughly discussed. The role of K+ in photosynthesis and the role of Na+ in charging the "battery of life" are pointed out. Also, the relationships between alkali metal ions and diseases (e. g. , Parkinson or traumatic brain injury) are covered and the relevance of Li+ salts in medicine (pharmacology and mechanism) is reviewed. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 16, The Alkali Metal Ions: Their Role for Life, which are written by 44 internationally recognized experts from 12 nations. The impact of this vibrant research area is manifested in nearly 3000 references, over 30 tables and more than 150 illustrations (two thirds in color). MILS-16 also provides excellent information for teaching. Astrid Sigel, Helmut Sigel, and Roland K. O. Sigel have long-standing interests in Biological Inorganic Chemistry. Their research focuses on metal ion interactions with nucleotides and nucleic acids and on related topics. They edited previously 44 volumes in the series Metal Ions in Biological Systems.

Alkaliphiles in Biotechnology (Advances in Biochemical Engineering/Biotechnology #172)

by Gashaw Mamo Bo Mattiasson

This book is devoted to alkaliphiles, their microbiology, biotechnological applications and adaptive mechanisms. Alkaliphiles are extremophilic organisms that are adapted to thrive in alkaline environments. Over the years, a wide variety of alkaliphiles belonging to domain Bacteria, Archaea and Eukarya have been isolated and studied. These organisms use various adaptive mechanisms to thrive in ‘extreme’ alkaline environments, and some of these adaptive mechanisms are of immense importance to a range of biotechnological applications. In this book, readers will learn about the adaptive strategies of alkaliphiles in colonizing alkaline habitats, with a main focus on: (1) the production of enzymes that are active and stable in the high pH environment, and (2) the production of acids that decrease the pH of their immediate surrounding environment. Enzymes that are operationally stable at high pH (also known as alkaline active enzymes) are desirable in several applications such as detergent formulating and leather tanning processes, and they are among the major selling enzymes and the most important industrial enzymes. The growing demand in many existing and emerging biotechnological applications led to the discovery, characterization, engineering and evaluation of diverse types of alkaline active enzymes. In addition to the use of these fascinating enzymes in biotechnological applications, readers will discover the mechanisms of action and stability of these enzymes at extreme pH. Studies have shown that some alkaliphiles decrease the severity of the high pH of their media by producing substantial amount of organic acids, which could be of great interest in various applications presented in this book. In addition to enzymes and organic acids, other products of biotechnological importance such as carotenoids, bioactive substances, and chelators have also attracted researchers’ attention. Whole-cells of alkaliphiles have been used as food and feed, and are also useful in environmental applications such as in waste treatment and construction.

Alkyne‐Based Nanostructures on Silver Substrates (Springer Theses)

by Raphael Hellwig

Acetylenic precursors are important reactants for creating carbon-based architectures via linkage reactions. While their capability of forming intermolecular bonds is well investigated in solution, very few systematic studies have been carried out to create alkyne-based nanostructures on metal substrates under ultra-high vacuum conditions. Synthesizing extended and regular carbon scaffolds requires a detailed knowledge of alkyne chemistry in order to control reaction pathways and limit unwanted side reactions. Using the bottom-up approach on metal surfaces, the authors establish protocols to fabricate regular architectures built up by the on-surface formation of selective organometallic and C-C bonds with thoughtfully designed alkyne-functionalized monomers. The structural and functional properties of the resulting organometallic and covalent nanostructures are characterized by means of scanning tunneling microscopy. The results open up new perspectives in the fields of heterogeneous catalysis and the on-surface synthesis of functional interfaces under mild reaction conditions.
