How does life work? How does nature produce the right numbers of zebras and lions on the African savanna, or fish in the ocean? How do our bodies produce the right numbers of cells in our organs and bloodstream? In The Serengeti Rules, award-winning biologist and author Sean B. Carroll tells the stories of the pioneering scientists who sought the answers to such simple yet profoundly important questions.

Not long ago, it was thought that the brain you were born with was the brain you would die with, and that the brain cells you had at birth were the most you would ever possess. Your brain was thought to be hardwired to function in predetermined ways. It turns out that's not true. Your brain is not hardwired; it's "softwired" by experience. This book shows you how you can rewire parts of the brain to feel more positive about your life, remain calm during stressful times, and improve your social relationships.

La Terra è il pianeta blu. Ma la nostra conoscenza del mare è spesso approssimativa e superficiale. L'autrice ci guida alla scoperta dei suoi abitanti adottando un punto di vista tutto particolare: il loro! Scopriremo così come si muovono, in che modo si corteggiano e riproducono, come percepiscono quanto li circonda e interagiscono tra loro. Nel mare troviamo un gran numero di specie viventi, molte ancora da scoprire. Conoscere la ricchezza e la fragilità del mondo sommerso significa anche porsi il problema di tutelarlo e difenderlo da un uso sconsiderato delle sue risorse.

Smallpox, the only infectious disease to have been eradicated, was one of the most terrifying of human scourges. It covered the skin with hideous, painful boils, killed a third of its victims, and left the survivors disfigured for life. In this riveting, often terrifying look at the history of smallpox, Jonathan B. Tucker tells the story of this deadly disease, the heroic efforts to eradicate it worldwide, and the looming dangers it still poses today.

Ignác Semmelweis is remembered for the now-commonplace notion that doctors must wash their hands before examining patients. In mid-19th century Vienna, however, this was a subversive idea. With deaths from childbed fever exploding, Semmelweis discovered that doctors themselves were spreading the disease. While his simple reforms worked immediately - childbed fever in Vienna all but disappeared - they brought down upon Semmelweis the wrath of the establishment, and led to his tragic end. 

We live in a factory-made world: modern life is built on three centuries of advances in factory production, efficiency, and technology. But giant factories have also fueled our fears about the future since their beginnings, when William Blake called them "dark Satanic mills". Many factories that operated over the last two centuries - such as Homestead, River Rouge, and Foxconn - were known for the labor exploitation and class warfare they engendered, not to mention the environmental devastation caused by factory production.

In Powering the Future, Nobel laureate Robert B. Laughlin transports us two centuries into the future, when we’ve ceased to use carbon from the ground. Boldly, Laughlin predicts no earth-shattering transformations will have taken place. Six generations from now, there will still be soccer moms, shopping malls, and business trips. Firesides will still be snug and warm.

I nostri geni non sono scolpiti nella pietra e i nostri fattori ereditari non sono un' "impronta digitale" fissa e immodificabile. Un essere umano infatti è molto più della somma dei suoi geni. Tutto quello che mangiamo, facciamo e sentiamo, tutto ciò che ci accade può influire sull'attività del DNA, a prescindere dalla configurazione genetica con la quale nasciamo. L'epigenetica, cioè la branca della genetica che si occupa di indagare le variazioni dell'espressione del nostro DNA, ci porta infatti una buona notizia: tali variazioni sono reversibili.

Feeding the world, climate change, biodiversity, antibiotics, and plastics - the list of concerns seems endless. But what is most pressing, what are the knock-on effects of our actions, and what should we do first? Do we all need to become vegetarian? How can we fly in a low-carbon world? Should we frack? How can we take control of technology? Does it all come down to population? And, given the global nature of the challenges we now face, what on Earth can any of us do?

For over a century, opening the black box of embryonic development was the holy grail of biology. Evo Devo--Evolutionary Developmental Biology--is the new science that has finally cracked open the box. Within the pages of his rich and riveting book, Sean B. Carroll explains how we are discovering that complex life is ironically much simpler than anyone ever expected.
