Genetic Science

C'est en étudiant la faune et la flore d'Amérique du Sud, lors de son voyage à bord du Beagle (de 1831 à 1836) que Charles Darwin va avoir l'intuition de la sélection naturelle, point central de sa théorie future de l'évolution des espèces. Publié en 1859, "L'origine des espèces" est un livre fondamental de la science moderne. À l'origine des théories de l'évolution, ce texte va révolutionner la compréhension du monde et fonder les bases de la biologie moderne, de la génétique, de l'éthologie et de l'écologie.

Uriel Ventris, newly ascended to the ranks of the Primaris, leads warriors of the Fourth Company from the Indomitus Crusade of Roboute Guilliman to a world on the frontiers of Ultramar. Once a battleground against the orks, Sycorax is now under furious assault from an enemy of ancient times – the necrons. The Ultramarines have faced these baleful xenos before, but Uriel senses the hand of a foe from his past at work on Sycorax, a tally unfinished and a debt to the Imperium finally come due.

Halek Cain has mysteries to solve, people to rescue, and a vendetta to carry out. But he must fix his Reaper augmentations before they kill him. He needs raw materials from Gronic, a technical specialist on Roxo III, and time to put himself right before the Union comes for him. Everything seems like it’s going to work out...until he learns Elise is in trouble. If Cain doesn’t get to her first, everything that happened on Dreadmax will have been for nothing. The Last Reaper will encounter assassins, Union special operators, and a mysterious rival from his past.

For Mack McKinley and his team of GhostWalker killing machines, urban warfare is an art. But despite a hard-won knowledge of the San Francisco streets, Mack knows from experience that too many things can still go wrong. Danger was just another part of the game--and now he's come face-to-face with a woman who can play just as tough. She's Jaimie, a woman with a sapphire stare so potent it can destroy a man. Years ago she and Mack had a history--volatile, erotic, and electric.

Trapped in history's vast expanse and burdened with immortality, King's journey transcends the ordinary, plunging him into epochs where legends and reality intertwine. From the ancient sands of Babylon to the birth of the American Revolution and through the Roman Empire at its zenith, King's exploits are a thrilling blend of historical intrigue and futuristic heroism. Whether he's rescuing a doomed Babylonian prince, navigating the treacherous waters of the Caribbean as an immortal pirate, or battling a plague-ridden Roman centurion, King's actions ripple through time.

GhostWalker Wyatt Fontenot knows the price he paid for the secret military experiments that gave him his special catlike abilities. After all, he left his bayou home a healer and came back a killer. While Wyatt and his GhostWalker brother Gator may have known exactly the sort of game they were getting into, Wyatt never anticipated where it would lead - or to whom.

In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.

From New York Times best-selling author Sam Kean come more incredible stories of science, history, language, and music, as told by our own DNA. There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking.

The Cajun dive in the middle of the godforsaken swamps wasn't exactly Trap Dawkins' idea of fun. But the GhostWalker wasn't there for a good time. He was looking for her. Cayenne. It's where she found her victims. Poor suckers. Then again, who wouldn't want to leave a place like this with a woman like her? It's not Cayenne's fault. Locked up, experimented on, and never knowing kindness, she was bred this way - with a heart of pure venom. Trap understands her.

In the early 1800s, a century before there was any concept of the gene, physicians in insane asylums began to record causes of madness in their admission books. Almost from the beginning, they pointed to heredity as the most important of these causes. As doctors and state officials steadily lost faith in the capacity of asylum care to stem the terrible increase of insanity, they began emphasizing the need to curb the reproduction of the insane. They became obsessed with identifying weak or tainted families and anticipating the outcomes of their marriages.

They call it Company Town - a city-size oil rig off the coast of the Canadian Maritimes, now owned by one very wealthy, powerful, byzantine family: Lynch Ltd. Hwa is of the few people in her community (which constitutes the whole rig) to forgo bioengineered enhancements. As such, she's the last truly organic person left on the rig - making her doubly an outsider as well as a neglected daughter and bodyguard extraordinaire.

Jack Sigler, call sign King, and the elite Chess Team operatives have been relentlessly hunting for their abducted former leader, Tom Duncan. An urgent call from George Pierce's shadowy Cerberus Group catapults them to the treacherous Southern Ocean, where they clash with ferocious prehistoric nightmares in a fight for survival.

In this lively and illuminating discussion of his landmark research, esteemed primatologist Frans de Waal argues that human morality is not imposed from above but instead comes from within. Moral behavior does not begin and end with religion but is in fact a product of evolution. For many years, de Waal has observed chimpanzees soothe distressed neighbors and bonobos share their food. Now he delivers fascinating fresh evidence for the seeds of ethical behavior in primate societies that further cements the case for the biological origins of human fairness.

Teagan Frost is having a hard time keeping it together. Sure, she's got telekinetic powers - a skill that the government is all too happy to make use of, sending her on secret break-in missions that no ordinary human could carry out. But all she really wants to do is kick back, have a beer, and pretend she's normal for once. But then a body turns up at the site of her last job - murdered in a way that only someone like Teagan could have pulled off. She's got 24 hours to clear her name - and it's not just her life at stake.

In September 1838, a young Englishman named Charles Darwin hit upon the idea that "natural selection" among competing individuals would lead to wondrous adaptations and species diversity. Twenty-one years passed between that epiphany and publication of On the Origin of Species. The human drama and scientific controversy of that time constitute a fascinating, tangled tale that illuminates this cautious naturalist who sparked an intellectual revolution.

The domestic cat—your cat—has, from its evolutionary origins in Africa, been transformed in comparatively little time into one of the most successful and diverse species on the planet. Jonathan Losos, writing as both a scientist and a cat lover, explores how researchers today are unraveling the secrets of the cat, past and present, using all the tools of modern technology, from GPS tracking (you’d be amazed where those backyard cats roam) and genomics (what is your so-called Siamese cat . . . really?) to forensic archaeology.

If the history of the Earth were compressed down to a year, our species would arise in the last thirty minutes or so of the final hour. But life itself is not such a late arrival: It has existed on Earth for something like 3.7 billion years—most of our planet’s history and over a quarter of the age of the universe (as far as we can tell). What have these organisms—bacteria, animals, plants, and the rest—done in all this time? In Living on Earth, the philosopher Peter Godfrey-Smith proposes a new way of understanding how the actions of living beings have shaped our planet.

When people started to develop superpowers, the world changed forever. Me? I wasn't one of the lucky ones with powers. So I had to develop more mundane skills, skills which have taken me across the globe on dangerous missions. But there are some missions I’ve always had to refuse. I've never been able to take on a super. They're just too powerful. They're gods, whereas I'm just a man, even with all my knowledge and training. All that changes after I discover my dad's secret research project.

Fifty thousand years ago, we were not the only species of human in the world. There were at least four others, including the Neanderthals, Homo floresiensis, Homo luzonesis and the Denisovans. At the forefront of the latter's ground-breaking discovery was Oxford Professor Tom Higham. In The World Before Us, he explains the scientific and technological advancements.

Self Comes to Mind is a nuanced and original chronicle of the evolution of the human brain. It reveals how the brain's development of a self becomes a challenge to nature's indifference and opens the way for the appearance of culture, a radical break in the course of evolution.
