Congo is rich. Swaths of the war-torn African country lack basic infrastructure, and, after many decades of colonial occupation, its people are officially among the poorest in the world. But hidden beneath the soil are vast quantities of cobalt, lithium, copper, tin, tantalum, tungsten, and other treasures. Recently, this veritable periodic table of resources has become extremely valuable because these metals are essential for the global “energy transition”—the plan for wealthy nations to wean themselves off fossil fuels by shifting to sustainable forms of energy, such as solar and wind.

In seinem berühmtesten Schriftstück liefert Alexander von Humboldt einen bemerkenswerten Text, der die Welt auf die endgültige Ausmessung derselbigen gründlich vorbereitete. Ein jeweils weit überproportionales Quantum an Erkenntnissucht, Abenteuerlust, Wissenschaftsgeist und Forscherdrang befähigten und beseelten diesen Mann ein bis dato unerreichtes Spektrum an geographischen, geologischen und naturwissenschaftlichen Fakten auf empirischer Basis in seinen Ansichten der Natur zu bündeln und dadurch dem geneigten Leser bzw.

Visual Friendlies, Tally Target: Surges continues the story of the role of forward air controllers (JTACs) and Close Air Support (CAS), picking up in 2006 and continuing through 2013. This volume covers the evolution of Joint Fires through the colloquial "second phase" of the War on Terror—the "surges" of Iraq in 2007 and Afghanistan in 2010–2011. Vol. II recounts the evolution of air power during the rising counterinsurgencies, as well as the psychology and mental makeup of these exclusive tribes.

Dr. Ashely Alker is a self-described death-escapologist--or, in more familiar terms, an emergency medicine doctor. She has seen it all, from flesh-eating bacteria to the work of a serial killer to the more mundane but no less deadly, and her work keeping people from dying (or being unable to) has uniquely prepared her to write this book.

When Trina Moyles was five years old, her father, a wildlife biologist known in Peace River as "the bear guy," brought home an orphaned black bear cub for a night before sending it to the Calgary Zoo. This brief but unforgettable encounter spurred Trina’s lifelong fascination with Ursus americanus—the most populous bear on the northern landscape, often considered a hindrance to human society.

Russian spies. Nuclear submarines. Sabotaged pipelines. Undersea communications severed in the dark of night. The fastest-warming place on earth—where apartment buildings, hospitals, and homes crumble daily as permafrost melts and villages get washed away by rising seas—the Arctic stands at the crossroads of geopolitical ambition and environmental catastrophe. As climate change thaws the northern latitudes, opening once ice-bound shipping lanes and access to natural resources, the world’s military powers are rushing to stake their claims in this increasingly strategic region.

From the NBC News correspondent and New York Times bestselling author of Separated, a gripping and revelatory account of the devastating 2025 Los Angeles fires, which he covered on the ground as an LA native.

ニューヨーク・タイムズベストセラー！テクノロジーの加速度的な進歩による人間社会の変化を予測して、ことごとく的中させてきたカーツワイルの最新話題作が、ついに日本上陸。彼が予測するAIが人間の知性を超える2029年はあと5年後に迫っている。

Whether we watch quick little songbirds at our backyard feeders, keep a flock of chickens, teach parrots to talk, or stand looking up at the sky, mesmerized by the aerial acrobatics of blackbirds gathering as the leaves turn in the fall, humans have an almost universal admiration of and interest in birds. We love the birdsong of spring, the fledglings in summer, the deep V of geese in autumn, the bright spot of red cardinals against white snow. Wild or domestic, birds are clearly one of God's best gifts.

In Evergreen, Cornell University professor Trent Preszler takes us on a riveting journey through history, culture, and science, exploring America’s story through the lives of its most resilient and cherished trees. From the annual hunt for the perfect Rockefeller Center spruce, back to the earliest days when Ancestral Puebloan builders crafted remarkable dwellings from pine beams, Evergreen reveals surprising connections between past and present that fueled America’s rise to global prominence.

As warming reshapes our planet, the Arctic—a region that once seemed unchangeable, beyond the reach of modern problems—is quickly coming undone. While the old cold world can still be glimpsed in the movements of caribou, the hidden lives of wolves, or the hunting skill of an Inupiat elder, look closer and you’ll find a new Arctic emerging in its place. In Frostlines, Neil Shea blends natural history, anthropology, and travel writing to explore how the beauty, chaos, and power of change in the far north are reflected in the lives of people and animals.

A firsthand, never-before-told account of the creation of OceanGate, the heartbreaking Titan tragedy, and the supposed villain behind it all, Stockton Rush, as told by the only person who can: his cofounder and friend.

What is going on with our atmosphere? The headlines are filled with news of devastating hurricanes, murderous tornadoes, and cataclysmic fires. Gale force advisories are issued on a regular basis by weather services around the world. Atmospheric scientists are warning that winds are expected to steadily increase in the years ahead, strengthening in power, speed, and frequency. While this prediction worried the insurance industry, governmental leaders, scientists, and conscientious citizens, one particular segment of society received it with unbridled enthusiasm.

To most, dreams are things that slip away when you reemerge into the waking world, their remnants jumbled up and only half recalled. At their best, they are populated by pleasant recollections and surreal experiences. But at their worst, they can be traumatizing and prevent us from receiving the necessary benefits of sleep. So why do we dream at all? What makes a person prone to nightmares? How do our bodies interface with our brains when we’re not awake? And how can we harness our sleeping minds to improve our waking lives?

Dr. Jessica Hernandez offers listeners an Indigenous, Global-South lens on the climate crisis, delivering a compelling and urgent exploration of its causes—and its costs. She shares how the impacts of colonial climate catastrophe—from warming oceans to forced displacement of settler ontologies—can only be addressed at the root if we reorient toward Indigenous science and follow the lead of Indigenous peoples and communities.

What are the moments that make a life? In Francis Crick’s, the decisive moment came in 1951, when he first met James Watson. Their ensuing discovery of the structure of DNA made Crick world-famous. But neither that chance meeting nor that discovery made Crick who he was. As Matthew Cobb shows in Crick, it is another chance encounter, with a line from the writing of Beat poet Michael McClure, that reveals Crick’s character: “THIS IS THE POWERFUL KNOWLEDGE,” it shouted. Crick, having read it, would keep it with him for the rest of his life.

Myriam Gurba has lived in California her entire life, with its plants and soils, forests and ecology, immersing herself in the language of the landscape as refracted through the languages and memories of her ancestors. In Poppy State, California plants serve as structural anchors in a wildly inventive work of narrative nonfiction that is part botanical criticism, part personal storytelling, part study of place. Gurba traverses themes of language, power, ancestry, and California's ecology, in masterfully constructed sentences that seem to defy gravity.

After we first launched Americans into space but before we touched down on the moon’s surface, there was the Gemini program. It was no easy jump from manned missions in low-Earth orbit to a successful moon landing, and the ten-flight, twenty-month celestial story of the Gemini program is an extraordinary one. There was unavoidable darkness in the program—the deaths and near-deaths that defined it, and the blood feud with the Soviet Union that animated it.

The spinosaurs – the controversial group that includes the largest land predator of all time, the awe-inspiring Spinosaurus – are brought to life in this cutting-edge review. The giant sail-backed carnivorous dinosaur Spinosaurus is one of the most famous of all dinosaurs; a staple of documentaries, books and video games, and the species that bested the mighty Tyrannosaurus rex in Jurassic Park III. The spinosaurs were some of the strangest predatory dinosaurs, combining a long low skull with powerfully clawed hands. Some species had huge sails over their backs, as well as fin-like tails.
