Mitochondria are tiny structures located inside our cells that carry out the essential task of producing energy for the cell. They are found in all complex living things, and in that sense, they are fundamental for driving complex life on the planet. But there is much more to them than that. Mitochondria have their own DNA, with their own small collection of genes, separate from those in the cell nucleus. It is thought that they were once bacteria living independent lives. Their enslavement within the larger cell was a turning point in the evolution of life, enabling the development of complex organisms and, closely related, the origin of two sexes. Unlike the DNA in the nucleus, mitochondrial DNA is passed down exclusively (or almost exclusively) via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to 'Mitochondrial Eve'. Mitochondria give us important information about our evolutionary history. And that's not all. Mitochondrial genes mutate much faster than those in the nucleus because of the free radicals produced in their energy-generating role. This high mutation rate lies behind our ageing and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer, through their involvement in precipitating cell suicide. Mitochondria, then, are pivotal in power, sex, and suicide. In this fascinating and thought-provoking book, Nick Lane brings together the latest research findings in this exciting field to show how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.

E = mc2 ist die berühmteste Formel der Welt. Mit ihr brachte Einstein es auf den Punkt: Energie und Masse sind zwei Seiten derselben Medaille und die Lichtgeschwindigkeit c ist ihr Wechselkurs. Doch warum besteht dieses so einfache Verhältnis? Wie ist Albert Einstein zu diesem Schluss gekommen? Und welche Folgen für das Verständnis des Universums ergeben sich daraus? Brian Cox, Professor für Physik und in England durch seine Sendungen auf BBC sehr bekannt, hat sich zusammen mit seinem Kollegen Jeff Forshaw, Professor für theoretische Physik, die scheinbar einfache Einstein-Gleichung vorgenommen, um sie mit viel Energie ausführlich und verständlich zu erklären.

Genesis Im Anfang w ar Leere: „Finsternis lag über der Ur ut“. Dann kam es zu einem gewaltigen Energieausbruch: „Es werde Licht. Und es wurde Licht.“ Woher diese Energie kam, weiß ich nicht. Bekannt ist jedoc h, was anschließend geschah: Die Energie kondensierte zu Materie und ihrem geheimn- vollen Spiegelbild – der Antimaterie – in vollkommen gl- chen Mengen. Gewöhnliche Materie ist uns vertraut; aus ihr bestehen Luft und Erde und die Lebewesen. Doch ihr getreues, in allen Erscheinungen identisches Spiegelbild, das erst im Inneren der Atome seine „verkehrte“ Natur offenbart, ist uns mehr als fremd. Es ist die Antimaterie, die Antithese zur Materie. Antimaterie gibt es heute nicht in größeren Mengen, zumindest nicht auf der Erde. Der Grund für ihr V- schwinden gehört zu den unerklärten Geheimnissen des Universums. Wir wissen aber, dass Antimaterie existiert, denn sie konnte in physikalischen Experimenten in win- gen Mengen hergestellt werden. Antimaterie zerstört jede gewöhnliche Materie, mit der sie in Berührung kommt, in einem grellen Blitz. Die seit XII Vorwort Milliarden von Jahren gebündelte Energie der Materie wird in einem solchen Augenblick explosionsartig frei- setzt. Antimaterie könnte die ideale Energiequelle werden, die Technologie des 21. Jahrhunderts. Doch ihre Fähigkeit zur absoluten Zerstörung könnte sie auch zu einer ulti- tiven Massenvernichtungswaffe machen.

Hundert schmale Seiten reichen, um die Physik der Moderne zu erklären Wo kommen wir her? Was können wir wissen? Seit ihren umwälzenden Entdeckungen im zwanzigsten Jahrhundert spüren Physiker den Kräften und Teilchen nach, die die Welt im Innersten und Äußersten zusammenhalten. Für jedermann verständlich, hat Carlo Rovelli dieses zauberhafte Buch darüber geschrieben. Es stürmte in wenigen Wochen an die Spitze der italienischen Bestsellerliste und wird derzeit in fast zwanzig Sprachen übersetzt. In eleganten, klaren Sätzen erklärt Rovelli die Physik der Moderne: Einstein und die Relativitätstheorie, Max Planck und die Quantenmechanik, die Entstehung des Universums, Schwarze Löcher, die Elementarteilchen, die Beschaffenheit von Raum und Zeit – und die Loop-Theorie, sein ureigenstes Arbeitsfeld. Ein Buch, das jeder verstehen kann – ein Lesevergnügen zum Staunen, Genießen und Mitreden können. «Von Natur aus wollen wir immer mehr wissen und immer weiter lernen. Unser Wissen über die Welt wächst. Uns treibt der Drang nach Erkenntnis und lernend stoßen wir an Grenzen. In den tiefsten Tiefen des Raumgewebes, im Ursprung des Kosmos, im Wesen der Zeit, im Schicksal der Schwarzen Löcher und im Funktionieren unseres eigenen Denkens. Hier, an den Grenzen unseres Wissens, wo sich das Meer unseres Nichtwissens vor uns auftut, leuchten das Geheimnis der Welt, die Schönheit der Welt, und es verschlägt uns den Atem.», schreibt Carlo Rovelli.

Alles ist Illusion – Margaret Atwoods Verneigung vor dem großen Bühnenmagier William Shakespeare Felix ist ein begnadeter Theatermacher und in der Szene ein Star. Seine Inszenierungen sind herausfordernd, aufregend, legendär. Nun will er Shakespeares „Der Sturm“ auf die Bühne bringen. Das soll ihn noch berühmter machen – und ihm helfen, eine private Tragödie zu vergessen. Doch nach einer eiskalten Intrige seiner engsten Mitarbeiter zieht sich Felix zurück, verliert sich in Erinnerungen und sinnt auf Rache. Die Gelegenheit kommt zwölf Jahre später, als ein Zufall die Verräter in seine Nähe bringt. In ihrem brillanten Roman schafft die große kanadische Autorin Margaret Atwood mit der Figur des Theaterdirektors Felix ein würdiges Pendant zu Shakespeares Prospero aus „Der Sturm“, jenes Zauberers, der als ein Selbstporträt des alternden Barden aus Stratford-on-Avon gilt.

Der Rückblick auf 100 Jahre Genetik ergibt eine faszinierende Geschichte, die in diesem Buch leicht und gut verständlich erzählt wird. Genforschung, Genetik in Landwirtschaft und Medizin sind viel verwendete Wörter in öffentlichen Debatten. Dabei ist nicht jedem bekannt, dass Genetik eine junge Wissenschaft ist, gerade einmal hundert Jahre alt. Der zentrale Begriff des Gens hat ständig neue Bedeutungen erhalten, oft befrachtet mit Ungenauigkeiten, wenn man an die Irrwege der Eugenik und an die Diskussion um die Vererbbarkeit von Intelligenz denkt.

Milton, Evil and Literary History

Category: Literary Criticism

Page: 168

Milton, Evil and Literary History addresses the ways in which we read literary history according to quite specific images of growth, development, progression, flourishing and succession. Goodness has always been aligned with a life of expansion, creation, production and fruition, while evil is associated with the inert, non-relational, static and stagnant. These associations have also underpinned a distinction between good and evil notions of capitalism, where good exchange enables agents to enhance their living potential and is contrasted with the evils of a capitalist system that circulates without any reference to life or spirit. Such images of a ghostly and technical economy divorced from animating origin are both central to Milton's theology and poetry and to the theories of literary history through which Milton is read. Regarded as a radical precursor to Romanticism, Milton's poetry supposedly requires the release of his radical spiritual content from the fetters of received orthodoxy. This literary and historical imagery of releasing the radical spirit of a text from the dead weight of received tradition is, this book argues, the dominant doxa of historicism and one which a counter-reading of Milton ought to question.

The Dome of Eden

A New Solution to the Problem of Creation and Evolution

What would biology look like if it took the problem of natural evil seriously? This book argues that biological descriptions of evolution are inherently moral, just as the biblical story of creation has biological implications. A complete account of evolution will therefore require theological input. The Dome of Eden does not try to harmonize evolution and creation. Harmonizers typically begin with Darwinism and then try to add just enough religion to make evolution more palatable, or they begin with Genesis and pry open the creation account just wide enough to let in a little bit of evolution. By contrast, Stephen Webb provides a theory of how evolution and theology fit together, and he argues that this kind of theory is required by the internal demands of both theology and biology. The Dome of Eden also develops a theological account of evolution that is distinct from the intelligent design movement. Webb shows how intelligent design properly discerns the inescapable dimension of purpose in nature but, like Darwinism itself, fails to make sense of the problem of natural evil. Finally, this book draws on the work of Karl Barth to advance a new reading of the Genesis narrative and the theology of Duns Scotus to provide the necessary metaphysical foundation for evolutionary thought.

We are in the midst of a revolution. It is a scientific revolution built upon the tools of molecular biology, with which we probe and prod the living world in ways unimaginable a few decades ago. Need to track a bacterium at the root of a hospital outbreak? No problem: the offending germ's complete genetic profile can be obtained in 24 hours. We insert human DNA into E. coli bacteria to produce our insulin. It is natural to look at biotechnology in the 21st century with a mix of wonder and fear. But biotechnology is not as 'unnatural' as one might think. All living organisms use the same molecular processes to replicate their genetic material and the same basic code to 'read' their genes. The similarities can be seen in their DNA. Here, John Archibald shows how evolution has been 'plugging-and-playing' with the subcellular components of life from the very beginning and continues to do so today. For evidence, we need look no further than the inner workings of our own cells. Molecular biology has allowed us to gaze back more than three billion years, revealing the microbial mergers and acquisitions that underpin the development of complex life. One Plus One Equals One tells the story of how we have come to this realization and its implications.

Erwin Schrödinger's 1944 classic What Is Life? is a small book that occupies a large place among the great written works of the twentieth century. It is said that it helped launch the modern revolution in biology and genetics, and inspired a generation of scientists, including Watson and Crick, to explore the riddle of life itself. Now, more than sixty years later, science writer Ed Regis offers an intriguing look at where this quest stands today. Regis ranges widely here, illuminating many diverse efforts to solve one of science's great mysteries. He examines the genesis of Schrödinger's great book--which first debuted as three public lectures in Dublin--and details the fantastic reception his ideas received, both in Europe and America. Regis also introduces us to the work of a remarkable group of scientists who are attempting literally to create life from scratch, starting with molecular components that they hope to assemble into the world's first synthetic living cell. The book also examines how scientists have unlocked the "three secrets of life," describes the key role played by ATP ("the ultimate driving force of all life"), and outlines the many attempts to explain how life first arose on earth, a puzzle that has given birth to a wide range of theories (which Francis Crick dismissed as "too much speculation running after too few facts"), from the primordial sandwich theory, to the theory that life arose in clay, in deep-sea vents, or in oily bubbles at the seashore, right up to Freeman Dyson's "theory of double origins." Written in a lively and accessible style, and bringing together a wide range of cutting-edge research, What is Life? makes an illuminating contribution to this ancient and ever-fascinating debate.

With the arrival of genomics and genome sequencing projects, biology has been transformed into an incredibly data-rich science. The vast amount of information generated has made computational analysis critical and has increased demand for skilled bioinformaticians. Designed for biologists without previous programming experience, this textbook provides a hands-on introduction to Unix, Perl and other tools used in sequence bioinformatics. Relevant biological topics are used throughout the book and are combined with practical bioinformatics examples, leading students through the process from biological problem to computational solution. All of the Perl scripts, sequence and database files used in the book are available for download at the accompanying website, allowing the reader to easily follow each example using their own computer. Programming examples are kept at an introductory level, avoiding complex mathematics that students often find daunting. The book demonstrates that even simple programs can provide powerful solutions to many complex bioinformatics problems.

Sexual Difference Between Psychoanalysis and Vitalism

Throughout the twentieth century, psychoanalysis and feminism were the practico-intellectual fields most systematic and subversive in demonstrating that humanity is sexually fissured. More recently, further advances in the philosophy of difference and renewed emphases on embodiment, materiality and life offer possibilities for attending to dimensions of gender and sexuality that were previously underdeveloped. This collection examines these possibilities insofar as they can either deepen or displace the traditional centrality of psychoanalysis in matters sexual. The authors come from a wide range of backgrounds and defend their approaches to the problem of sexual difference in a variety of idioms, drawing on key thinkers such as Lacan, Irigaray, Deleuze, Foucault and Badiou. It is rare to come across these thinkers together; but sex is too crucial a site for critical thought not to mobilize every conceptual power available. This book was originally published as a special issue of the journal Angelaki: The Journal of the Theoretical Humanities.
