Four billion years ago, the infant Earth was a seething cauldron of erupting volcanoes, raining meteors, and hot noxious gases, totally devoid of life. But a relatively short time later-only 100 million to 200 million years-the planet was teeming with primitive organisms.What happened? Now you can find out-in a series of 24 vibrant lectures from a leader of the NASA-supported team studying the origins of life in the universe and also one of the nation's foremost science educators.

We use DNA routinely - to cure diseases, solve crimes, and reunite families. Yet we've known about it for only 60 years. And what we're continuing to learn about it every day has the potential to transform our health, our nutrition, our society, and our future. But what, exactly is DNA, the self-replicating material present in nearly all living organisms?

In 24 thought-provoking lectures designed for nonscientists, this course explores today's exciting field of genomics, the study of the vast storehouse of information contained within chromosomes. Your professor is Princeton University biologist Lee M. Silver, an acclaimed teacher, scientist, and author of popular books on biotechnology, genetics, and their impact on society.

Los insectos son el grupo más numeroso del reino animal. Información general sobre las abejas. La colmena: características, zánganos, abejas reina, obreras, funciones. Las abejas y el ecosistema.

The topic of neurotheology has garnered increasing attention in the academic, religious, scientific, and popular worlds. But there have been no attempts to explore more specifically how Jewish religious thought and experience may intersect with neurotheology. The Rabbi's Brain engages this groundbreaking area.

Ever wonder why onions make you cry? Or why lizards do pushups? Or why leaves change color in the fall? Don't worry, you're not alone. Acclaimed science writer and broadcaster Jay Ingram wonders the same things. After a long career of asking important questions (does time speed up as we age? How much Neanderthal is in me? Why do some animals throw their feces?), he's here to put our scientific quandaries to rest.

I hate every wave of the ocean', the seasick Charles Darwin wrote to his family during his five-year voyage on the H.M.S. Beagle. It was this world-wide journey, however, that launched the scientists career.

Fifty thousand years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special.

Charles Darwin, el precursor de la literatura científica, expuso en El origen de las especies su famosa teoría de la biología evolutiva y la selección natural. Fue una publicación polémica que suscitó discusiones científicas, filosóficas y religiosas; sin embargo, hoy, la teoría moderna de la evolución acepta las tesis sobre la adaptación al medio ambiente de una especie para sobrevivir y su lenta, pero evidente, evolución.

Sebbene esista la convinzione che parlare alle piante ne favorisca la crescita, sembra tuttavia alquanto strano immaginare che le piante abbiano una vita mentale. Se però consideriamo che pensare non è altro che la capacità di recepire stimoli dall'ambiente, elaborarli e mettere in atto strategie per sopravvivere, allora possiamo ritenere che le piante abbiano una qualche forma di pensiero e intelligenza. L'autore ci introduce nel mondo delle piante e ne svela i segreti.

Kinder stellen tausend Fragen. Wir Erwachsenen hingegen trauen uns oft nicht mehr, genau nachzufragen. Schließlich müssten wir es ja längst wissen. Bedauerlicherweise werden viele Themen so kompliziert erklärt, dass den meisten von uns schon nach kurzer Beschäftigung damit die Lust am Wissen vergeht. Doch es geht auch anders! Dieses Hörbuch ist für all die wissensdurstigen Menschen produziert worden, die sich nicht damit abfinden wollen, etwas nicht zu verstehen.

Un son, une note, une mélodie et voilà...le cerveau en effervescence. Mais pourquoi certains airs arrivent-ils à nous tirer des larmes, à nous donner la chair de poule, à nous enthousiasmer ou à nous faire danser? Journaliste scientifique aguerri, Michel Rochon nous entraîne dans une exploration fascinante du cerveau musical. Il nous révèle les plus récentes découvertes en intelligence artificielle, en neuropsychologie, en linguistique et même en mathématiques qui nous font comprendre autrement les harmonies sonores.

Que se passe-t-il donc dans la tête d’un Homo sapiens lorsqu’une passion amoureuse l’entraîne dans la déraison et les extravagances? Ou bien lorsqu’une animosité en lui se transforme en sentiment de haine ? Les neurosciences nous éclairent maintenant très bien sur ces deux pulsions – amour, haine – qui sont, l’une et l’autre, des rouages essentiels à notre survie. Elles constituent des processus neuronaux ancestraux encore sollicités et restés très actifs.

From cork taint, to volatile acidity, to off-putting aromas and flavors, all wine connoisseurs have encountered unappealing qualities in a disappointing bottle. But are all faults truly bad? Are some even desirable? Jamie Goode brings his authoritative voice to the table once again to demystify the science behind what causes a good bottle to go bad. By exposing the root causes of faults in wine, Flawless challenges us to rethink our assumptions about how wine should taste and how we can understand beauty in a glass.

There's a silent epidemic in Western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

There is no one better qualified than Jared Diamond - renowned expert in the fields of physiology and evolutionary biology and award-winning author - to explain the evolutionary forces that operated on our ancestors to make us sexually different. With wit and a wealth of fascinating examples, he explains how our sexuality has been as crucial as our large brains and upright posture in our rise to human status.

Neuroscience in small bits for the brain-curious. From magazine covers to Hollywood blockbusters, neuroscience is front and center. This popular interest has inspired many questions from people who wonder just what is going on in the three pounds of tissue between their ears.

What scientific concept would improve everybody's cognitive toolkit? This is the question John Brockman, publisher of Edge.org, posed to the world's most influential thinkers. Their visionary answers flow from the frontiers of psychology, philosophy, economics, physics, sociology, and more. Surprising and enlightening, these insights will revolutionize the way you think about yourself and the world.

As ecologists Paul Jepson and Cain Blythe show, rewilding is a new and progressive approach to conservation, blending radical scientific insights with practical innovations to revive ecological processes, benefiting people as well as nature. With its sense of hope and purpose, rewilding is breathing new life into the conservation movement and enabling a growing number of people to enjoy thrilling wildlife experiences previously accessible only in remote wilderness reserves.
