The British believe that, through ingenuity and scientific prowess, they alone have a war-winning weapon: radar. They are wrong. The Germans have it too. They believe that their unique maritime history means their pilots have no need of navigational aids. Flying above the clouds they, like the seafarers of old, had the stars to guide them, and that is all that is required. They are wrong. Most of the bombs the RAF will drop in the first years of the war land miles from their target.

After Hurricane Katrina struck and power failed, amid rising floodwaters and heat, exhausted staff at Memorial Medical Center designated certain patients last for rescue. Months later, a doctor and two nurses were arrested and accused of injecting some of those patients with life-ending drugs.

From the plains of ancient Mesopotamia to the rolling hills of medieval England to the vast sheep farms of modern-day Australia, sheep have been central to the human story. Starting with our Neolithic ancestors' first forays into sheep-rearing nearly 10,000 years ago, these remarkable animals have fed us, clothed us, changed our diet and languages, helped us to win wars, decorated our homes and financed the conquest of large swathes of the earth.

A significant number of Americans, especially evangelical Christians, believe Earth and humankind were created in their present form sometime in the last 10,000 years or so - the rationale being that this is (presumably) the story told in the book of Genesis. Within that group, any threatening scientific evidence that suggests otherwise is rejected or, when possible, retrofitted into a creationist worldview.

This classic of spycraft is based on Allen Dulles's incomparable experience as a diplomat, international lawyer, and America's premier intelligence officer. Dulles was a high-ranking officer of the CIA's predecessor - the Office of Strategic Services - and was present at the inception of the CIA, where he served eight of his 10 years there as director. Here he sums up what he learned about intelligence from nearly a half-century of experience in foreign affairs.

Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past?

Travelling at almost 18,000 miles per hour - 10 times faster than a rifle bullet - Yuri Gagarin circles the globe in just 106 minutes. From his windows, he sees the Earth as nobody has before, crossing a sunset and a sunrise, crossing oceans and continents, witnessing its beauty and its fragility. While his launch begins in total secrecy, within hours of his landing, he has become a world celebrity - the first human to leave the planet. Beyond tells the thrilling story behind that epic flight on its 60th anniversary.

How did the replication bomb we call "life" begin, and where in the world, or rather, in the universe, is it heading? Writing with characteristic wit and an ability to clarify complex phenomena (the New York Times described his style as "[T]he sort of science writing that makes the reader feel like a genius"), Richard Dawkins confronts this ancient mystery.

Time moves forward, not backward---everyone knows you can't unscramble an egg. In the hands of one of today's hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself---a period of modern cosmology of which Einstein never dreamed.

In the summer of 1938, botanists Elzada Clover and Lois Jotter set off to run the Colorado River, accompanied by an ambitious and entrepreneurial expedition leader, a zoologist, and two amateur boatmen. With its churning waters and treacherous boulders, the Colorado was famed as the most dangerous river in the world. Journalists and veteran river runners boldly proclaimed that the motley crew would never make it out alive. But for Clover and Jotter, the expedition held a tantalizing appeal: no one had yet surveyed the plant life of the Grand Canyon, and they were determined to be the first.

On June 6, 1761, the world paused to observe a momentous occasion: the first transit of Venus between the earth and the sun in more than a century. Through that observation, astronomers could calculate the size of the solar system - but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.

The knowledge of death is so terrifying that we live most of our lives in denial of it. One of the most difficult moments of childhood must be when each of us first realizes that not only we but all our loved ones will die—and there is nothing we can do about it. Or at least, there hasn’t been. Today, we are living through a revolution in biology. Giant strides are being made in understanding why we age—and why some species live longer than others. Could we eventually cheat disease and death and live for a very long time, possibly many times our current lifespan?
