North America's biggest cat was once killed for bounty dollars, slaughtered with impunity and driven toward extinction. But today's cat of intrigue, despite our lingering fears and misconceptions, has returned to much of its native range in the western United States and gained respect as a predator integral and necessary to wild ecosystems. This turnaround was triggered by one man: Maurice Hornocker. Cougars on the Cliff recounts the early years of his research when he tracked lions following a dog's nose and footprints in the snow—before telemetry was available.

More than 50 years ago, John Coltrane drew the 12 musical notes in a circle and connected them with straight lines, forming a five-pointed star. Inspired by Einstein, Coltrane had put physics and geometry at the core of his music. Physicist and jazz musician Stephon Alexander returns the favor, using jazz to answer physics' most vexing questions about the past and future of the universe.

Bill Gates, more commonly known as the founder of Microsoft and richest man on the planet for almost two decades, has been defined by most people by the number that represented his wealth.

With railroads scarring virgin lands and the formerly vast buffalo herds decimated, the country faced a crossroads: Could it pursue Manifest Destiny without destroying its natural bounty and beauty? The alarm that Grinnell sounded would spark America's conservation movement. Yet today his name has been forgotten - an omission that John Taliaferro's commanding biography now sets right with historical care and narrative flair.

Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

When he died in 1930 aged 26, Frank Ramsey had already invented one branch of mathematics and two branches of economics, laying the foundations for decision theory and game theory. Keynes deferred to him; he was the only philosopher whom Wittgenstein treated as an equal. Had he lived he might have been recognized as the most brilliant thinker of the century. This amiable shambling bear of a man was an ardent socialist, a believer in free love, and an intimate of the Bloomsbury set. For the first time Cheryl Misak tells the full story of his extraordinary life.

Everyone has heard of DNA. But by itself, DNA is just an inert blueprint for life. It is the ribosome - an enormous molecular machine made up of a million atoms - that makes DNA come to life, turning our genetic code into proteins and therefore into us. Gene Machine is an insider account of the race for the structure of the ribosome, a fundamental discovery that both advances our knowledge of all life and could lead to the development of better antibiotics against life-threatening diseases.

In 1910, Mary Acworth Evershed (1867-1949) sat on a hill in southern India staring at the moon as she grappled with apparent mistakes in Dante's Divine Comedy. Was Dante's astronomy unintelligible? Or was he, for a man of his time and place, as insightful as one could be about the sky? As the 20th century began, women who wished to become professional astronomers faced difficult cultural barriers, but Evershed joined the British Astronomical Association and, from an Indian observatory, became an experienced observer of sunspots, solar eclipses, and variable stars.

Nixon declared the war on cancer in 1971. Forty-five years and billions of dollars later, it looks like we have lost the battle. Or have we? When a natural, non-toxic way to fight cancer is discovered, it is big news in the scientific community. But instead of being embraced, it is fiercely opposed by those tied to the pharmaceutical industry. Research by the late Mirko Beljanski, PhD, - one of the first green molecular biologists - revealed that natural molecules can selectively target cancer cells and work alongside many chemotherapy drugs.

"Ants are the most warlike of all animals, with colony pitted against colony.... Their clashes dwarf Waterloo and Gettysburg", writes Edward O. Wilson in his most finely observed work in decades. In a myrmecological tour to such far-flung destinations as Mozambique and New Guinea, the Gulf of Mexico's Dauphin Island and even his parents' overgrown yard back in Alabama, Wilson thrillingly evokes his nine-decade-long scientific obsession with more than 15,000 ant species.

On March 14, 1889, Susan La Flesche received her medical degree - becoming the first Native American doctor in US history. She earned her degree 31 years before women could vote and 35 years before Indians could become citizens in their own country. This is the story of an Indian woman who effectively became the chief of an entrenched patriarchal tribe, the story of a woman who crashed through thick walls of ethnic, racial, and gender prejudice and then spent the rest of her life using a unique bicultural identity to improve the lot of her people.
