Book Description
This volume is the edited proceedings of a conference seeking to clarify the possible role of clays in the origin of life on Earth. At the heart of the problem of the origin of life lie fundamental questions such as: What kind of properties is a model of a primitive living system required to exhibit and what would its most plausible chemical and molecular makeup be? Answers to these questions have traditionally been sought in terms of properties that are held to be common to all contemporary organisms. However, there are a number of different ideas both on the nature and on the evolutionary priority of 'common vital properties', notably those based on protoplasmic, biochemical and genetic theories of life. This is therefore the first area for consideration in this volume and the contributors then examine to what extent the properties of clay match those required by the substance which acted as the template for life.

Book Description
"The Mechanism of Life" is a groundbreaking work by the French physiologist and biochemist Stéphane Leduc, originally published in 1911 under the title "La Biologie Synthétique." In this influential book, Leduc explores the idea of a mechanistic approach to understanding the fundamental processes of life, challenging traditional biological perspectives of his time. Leduc was a proponent of the concept that living organisms could be understood through principles of physics and chemistry, akin to a machine. He proposed that life processes could be explained through the physical and chemical interactions of living matter. Leduc's work was particularly notable for its attempt to synthesize life-like phenomena in the laboratory, using chemical substances to create structures resembling cells and even imitating some aspects of cellular functions. One of the key concepts in "The Mechanism of Life" is the idea of osmotic phenomena, wherein Leduc explored the role of osmosis in cellular processes. He conducted experiments involving the formation of artificial cells, referred to as "osmotic growths," by encapsulating various substances in semi-permeable membranes. Leduc's work was met with both acclaim and criticism. While some praised his innovative thinking and experimental techniques, others were skeptical of his mechanistic approach to understanding the complexity of living organisms. Over time, some of Leduc's ideas fell out of favor as the field of biology evolved, embracing more nuanced and holistic approaches to studying life. Despite its eventual historical context, "The Mechanism of Life" remains an important work in the history of biology, as it reflects an early attempt to bridge the gap between physics, chemistry, and the intricacies of living organisms. The book provides valuable insights into the scientific thinking of its time and the evolving understanding of life processes.

Book Description
The editors of Mast Cell Biology, Drs. Gilfillan and Metcalfe, have enlisted an outstanding group of investigators to discuss the emerging concepts in mast cell biology with respect to development of these cells, their homeostasis, their activation, as well as their roles in maintaining health on the one hand and on the other, their participation in disease.

Book Description
A groundbreaking, witty, and eloquent exploration of slime that will leave you appreciating the nebulous and neglected sticky stuff that covers our world, inside and out. Slime. The very word seems to ooze oily menace, conjuring up a variety of unpleasant associations: mucous, toxins, reptiles, pollutants, and other unsavory viscous semi-liquid substances. Yet without slime, the natural world would be completely unrecognizable; in fact, life itself as we know it would be impossible In this deft and fascinating book, journalist Susanne Wedlich takes us on a tour of all things slimy, from the most unctuous of science fiction monsters to the biochemical compounds that are the very building blocks of life. Along the way she shows us what slime really means, and why slime is not something to fear, but rather something to ... embrace.

Book Description
Brilliant and engagingly written, Why Nations Fail answers the question that has stumped the experts for centuries: Why are some nations rich and others poor, divided by wealth and poverty, health and sickness, food and famine? Is it culture, the weather, geography? Perhaps ignorance of what the right policies are? Simply, no. None of these factors is either definitive or destiny. Otherwise, how to explain why Botswana has become one of the fastest growing countries in the world, while other African nations, such as Zimbabwe, the Congo, and Sierra Leone, are mired in poverty and violence? Daron Acemoglu and James Robinson conclusively show that it is man-made political and economic institutions that underlie economic success (or lack of it). Korea, to take just one of their fascinating examples, is a remarkably homogeneous nation, yet the people of North Korea are among the poorest on earth while their brothers and sisters in South Korea are among the richest. The south forged a society that created incentives, rewarded innovation, and allowed everyone to participate in economic opportunities. The economic success thus spurred was sustained because the government became accountable and responsive to citizens and the great mass of people. Sadly, the people of the north have endured decades of famine, political repression, and very different economic institutions—with no end in sight. The differences between the Koreas is due to the politics that created these completely different institutional trajectories. Based on fifteen years of original research Acemoglu and Robinson marshall extraordinary historical evidence from the Roman Empire, the Mayan city-states, medieval Venice, the Soviet Union, Latin America, England, Europe, the United States, and Africa to build a new theory of political economy with great relevance for the big questions of today, including: - China has built an authoritarian growth machine. Will it continue to grow at such high speed and overwhelm the West? - Are America’s best days behind it? Are we moving from a virtuous circle in which efforts by elites to aggrandize power are resisted to a vicious one that enriches and empowers a small minority? - What is the most effective way to help move billions of people from the rut of poverty to prosperity? More philanthropy from the wealthy nations of the West? Or learning the hard-won lessons of Acemoglu and Robinson’s breakthrough ideas on the interplay between inclusive political and economic institutions? Why Nations Fail will change the way you look at—and understand—the world.
