In this smart and funny book, celebrated cartoonist Zach Weinersmith and noted researcher Dr. Kelly Weinersmith give us a snapshot of what's coming next - from robot swarms to nuclear fusion powered-toasters. By weaving their own research and interviews with the scientists who are making these advances happen, the Weinersmiths investigate why these technologies are needed, how they would work, and what is standing in their way.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely. 

„Der Weg zu mir selbst führte mich zurück auf die Kuhweide.“ - Joar Berge Joar Berge besaß schon als Kind eine außergewöhnliche Verbindung zu Kühen, die sein gesamtes Leben prägen sollte. Nach Jahren exzessiven Stadtlebens in verschiedenen Metropolen folgt Joar seinem eigentlichen Traum und schenkt den Rindern Dagi und Emma einen Lebensplatz. Diese Entscheidung gab seinem Leben eine komplett andere Richtung und offenbarte ihm den Stellenwert besonderer Tier-Mensch-Beziehungen.

Before the discovery of insulin, diabetes was treated almost exclusively through diet, from subsistence on meat, to reliance on fats, to repeated fasting and near-starvation regimens. After two centuries of conflicting medical advice, most authorities today believe that those with diabetes can have the same dietary freedom enjoyed by the rest of us, leaving the job of controlling their disease to insulin therapy and other blood-sugar-lowering medications.

As the fracture lines between nations grow ever wider, how do we relate to each other, to the land on which we live and the world around us? Are we united enough to see protection of the natural environment as a priority? These are the questions Raynor asks herself as she embarks on her most ambitious walk to date with her husband Moth—from the dramatic beauty of the Cape Wrath Trail in the north-west corner of Scotland, to the familiar territory of the South-west Coast Path.

From earth's nations and inhabitants, through the fuels and foods that energise them, to the transportation and inventions of our modern world - and how all of this affects the planet itself - in Numbers Don't Lie, Professor Vaclav Smil takes us on a fact-finding adventure, using surprising statistics and illuminating graphs to challenge lazy thinking.

In early May 2006, a young British climber named David Sharp lay dying near the top of Mount Everest while forty other climbers walked past him on their way to the summit. A week later, Lincoln Hall, a seasoned Australian climber, was left for dead near the same spot. Hall's death was reported around the world, but the next day he was found alive after spending the night on the upper mountain with no food and no shelter.

Discover magazine recently called Richard Dawkins "Darwin's Rottweiler" for his fierce and effective defense of evolution. Prospect magazine voted him among the top three public intellectuals in the world (along with Umberto Eco and Noam Chomsky). Now Dawkins turns his considerable intellect on religion, denouncing its faulty logic and the suffering it causes.

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: Observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria.

We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet - having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and created breathtaking works of art - while chimps remain animals concerned primarily with the basic necessities of survival. What is it about that two percent difference in DNA that has created such a divergence between evolutionary cousins?

Wir sind ohne Zweifel ein Wunder der Evolution. Unsere außergewöhnlichen körperlichen Eigenschaften und unsere Innovationen haben unsere Zivilisationen geschaffen. Aber wir sind auch zutiefst fehlerbehaftet. Unsere Körper brechen, ersticken und versagen, ob wir nun Könige oder Bauern sind. Krankheiten durchkreuzen unsere kühnsten Pläne, unsere Psyche ist die Ursache für schreckliche Entscheidungen in Krieg und Frieden. Diese faszinierende Widersprüchlichkeit ist die Essenz des Menschseins: die Summe unserer Schwächen und unserer Stärken, zwischen denen sich die Historie bewegt.

Der große Naturforscher und Universalgelehrte lässt Muschelverkalkungen und Sternschnuppen vom Ursprung der Welt erzählen, berichtet von Schwarzen Löchern, fernen Kometen, der Schönheit der Natur der Tropen und des Eismeers. Er lehrt uns das Staunen und weckt in uns die Lust, weiter zu fragen: Wie schön wäre es doch, wenn man mehr wüsste... Humboldts populärwissenschaftlichen Kosmos-Vorlesungen, die die Keimzelle seines großes Werkes bilden, lauschte einst halb Berlin - vom Arbeiter bis zur Hofgesellschaft.

In this landmark book of popular science, Daniel E. Lieberman - chair of the department of human evolutionary biology at Harvard University and a leader in the field - gives us a lucid and engaging account of how the human body evolved over millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic disease.

Nie war der Traum vom ewigen Leben so aktuell wie heute. Jung, aktiv, gesund und attraktiv wollen wir sein, und das auch im hohen Alter. Nun haben Wissenschaftler das große Rätsel unserer Vergänglichkeit entschlüsselt. Und sie haben erste Techniken entwickelt, die den Alterungsprozess kontrollieren. Der Wissenschaftsjournalist Ulrich Bahnsen nimmt uns mit auf eine spannende Reise zu den weltweit führenden Altersforscher:innen und entdeckt epigenetische Therapien, mit deren Hilfe wir unseren Körper um Jahrzehnte verjüngen können.

The term metaverse is suddenly everywhere, from debates over Fortnite to the pages of the New York Times to the speeches of Mark Zuckerberg, who proclaimed in June 2021 that “the overarching goal” of Facebook is to “bring the metaverse to life”. But what, exactly, is the metaverse? As pioneering theorist and venture capitalist Matthew Ball explains, it is the successor to the mobile internet that has defined the last two decades.

What is it about the top tech product companies such as Amazon, Apple, Google, Netflix, and Tesla that enables their record of consistent innovation? Most people think it's because these companies are somehow able to find and attract a level of talent that makes this innovation possible. But the real advantage these companies have is not so much who they hire, but rather how they enable their people to work together to solve hard problems and create extraordinary products. 

Verstehe sich, wer kann! Liebe und Zuneigung, Schuld und Schadenfreude, Wut und Nachsicht - unsere Gefühle werden vom Gehirn gesteuert. Doch was genau passiert in unserem Kopf, wenn wir streiten, lieben oder schmollen? Sind wir noch gutherzig, wenn wir's danach auf Facebook posten? Wo lauern die Denkfehler, die uns das Zusammenleben so schwer machen? Wie überlebt das Gehirn ein Arbeitsessen oder ein Paargespräch? Und wo wir gerade dabei sind: Wäre eine einsame Insel nicht doch die bessere Option?

Shockingly, we spend nearly half our day repeating things we've done in the past without thinking about them. How we respond to the people around us; the way we conduct ourselves in meetings; what we buy; when and how we exercise, eat and drink – a truly remarkable number of things we do every day, we do by habit. And yet, whenever we want to change something about ourselves, we rely on willpower alone. We hope that our determination and intention will be enough to effect positive change.

Klimawandel, soziale Ungerechtigkeit, Ausbeutung... es steht nicht gut um unsere Welt. Das ist die Wahrheit. Leider. Doch Sven Plöger, Meteorologe und Klimaexperte und Christoph Waffenschmidt, Deutschland-Chef der weltweiten Hilfsorganisation World Vision, kennen auch eine andere, eine motivierende, Hoffnung machende Perspektive: Wir können etwas tun! Gemeinsam nehmen die beiden Freunde den Leser mit auf ihre ganz persönliche Reise zu Menschen rund um den Globus, die mutig losgehen und die Welt ein bisschen besser machen.
