La storia del nostro pianeta è inscindibilmente legata alla storia della vita sulla terra e alla sua straordinaria varietà. Senza la biodiversità la vita scomparirebbe. Nell'immensa comunità naturale di cui facciamo parte essa infatti consente a tutti i suoi componenti di modificarsi moltiplicando le strategie di sopravvivenza per adattarsi alla mutevolezza dei contesti. L'autore analizza dapprima strutture e funzioni della biodiversità - a tutti i livelli della biosfera tra loro interconnessi e complementari - dalle molecole agli organismi, alle specie, agli ecosistemi.

Da sempre l'uomo ha selezionato piante, animali, microrganismi per soddisfare i suoi bisogni. Oggi le biotecnologie avanzate permettono di trasferire geni fra organismi che non è possibile incrociare naturalmente, ma con effetti altamente imprevedibili. Il volume, ripresentato in edizione aggiornata, muove da una descrizione dei meccanismi che regolano il delicato equilibrio alla base della vita e spiega perché occorre essere cauti quando lo si modifica drasticamente.

The great scientists Louis Pasteur (1822-1893) and Joseph Lister (1827-1912) revolutionized medical practice in the 19th century. Pasteur's discovery of the cause of fermentation formed the basis of modern germ theory while Lister developed antiseptic surgical methods based on that. The book contains a description of the theory, and accounts of their work and experiments.

Is the five-second rule legitimate? Are electric hand dryers really bacteria blowers? How gross is backwash? When it comes to food safety and germs, there are as many common questions as there are misconceptions. And yet there has never been a book that clearly examines the science behind these important issues - until now.

The question of how and why organisms age has teased scientists for centuries. There are myriad competing theories, from the idea that ageing is a simple wear and tear process, like the rusting of a car, to the belief that ageing and death are genetically programmed and controlled. In fact, there is no clearly defined limit to life and no single, predictable program playing itself out: different things are happening within and between tissues, and each system or organ accumulates damage at its own pace, according to the kind of insults imposed on it by daily living.

Nachdem sich die moderne Hirnforschung in den letzten zwanzig Jahren rasant entwickelte, hat auch das Interesse an ihren Resultaten zugenommen. Was will der Mensch? Entscheidet er selbst? Oder ist er nur das Opfer chemischer und neuronaler Affekte? Das sind spannende Fragen, besonders für Werbung und Kommunikation. Wie nimmt der Mensch wahr? Und vor allem: Was nimmt er auf? Werner T. Fuchs beschäftigt sich seit Jahren mit der Umsetzung moderner Hirnforschung ins Marketing. Seine These - inzwischen von der Hirnforschung untermauert - lautet: Der Mensch lernt durch Geschichten. Wer diese Erkenntnis in die Praxis einfließen lässt, wird sein Gegenüber besser erreichen. Fuchs hat zwölf leicht zu verstehende, unterhaltsame "Werkzeuge" kreiert, die helfen, Kommunikation grundsätzlich neu zu verstehen und auf die Arbeitsweise des Gehirns abzustimmen.

Why are we the way we are? Why do some of us find it impossible to calm a quick temper or to shake anxiety? The debate has always been divided between nature and nurture, but as psychology professor Daniel P. Keating demonstrates in Born Anxious, new DNA science points to a third factor that allows us to inherit both the nature and the nurture of previous generations - with significant consequences.
