For centuries, dyed fabrics ranked among the most expensive objects of the ancient Mediterranean world, fetching up to 20 times their weight in gold. Huge fortunes were made from and lost to them, and battles were fought over control of the industry. The few who knew the dyes’ complex secrets carefully guarded the valuable knowledge. The Rarest Blue tells the amazing story of tekhelet, or hyacinth blue, the elusive sky-blue dye mentioned 50 times in the Hebrew Bible. The Minoans discovered it; the Phoenicians stole the technique; Cleopatra adored it; and Jews—obeying a Biblical commandment to affix a single thread of the radiant color to the corner of their garments—risked their lives for it. But with the fall of the Roman Empire, the technique was lost to the ages. Then, in the nineteenth century, a marine biologist saw a fisherman smearing his shirt with snail guts, marveling as the yellow stains turned sky blue. But what was the secret? At the same time, a Hasidic master obsessed with reviving the ancient tradition posited that the source wasn’t a snail at all but a squid. Bitter fighting ensued until another rabbi discovered that one of them was wrong—but had an unscrupulous chemist deliberately deceived him? Baruch Sterman brilliantly recounts the complete, amazing story of this sacred dye that changed the color of history.

Travel across Earth to discover eight species that are blue in color and are either naturally rare, threatened, or endangered. Panoramic illustrations and a playful main text prompt a search for the blue species at hand, while the page-turn and informative sidebars zoom in to reveal a closer look at the species. There's a lot to uncover about the Karner blue butterfly, blue black bear, blue whale, Quitobacquito pupfish, Cerulean warbler, blue lobster, Eastern Indigo snake, and big bluestem grass. A surprise ending celebrates that planet Earth is the rarest and bluest and must be protected for the sake of all.

For centuries, blue and purple dyed fabrics ranked among the ancient world s most desirable objects, commanding many times their weight in gold. Few people knew their secrets, carefully guarding the valuable knowledge, and strict laws regulated their production and use. The Rarest Blue tells the incredible story of tekhelet, the elusive sky-blue color mentioned throughout the Bible. Minoans discovered it; Phoenicians stole it; Roman emperors revered it; and Jews obeying a commandment to affix a thread of it to their garments risked their lives for it. But as the Roman Empire dissolved, the color vanished. Then, in the nineteenth century, a marine biologist marveled as yellow snail guts smeared on a fisherman s shirt turned blue. But what had caused this incredible transformation? Meanwhile, a Hasidic master obsessed with the ancient technique posited that the source of the dye was no snail but a squid. Bitter controversy divided European Jews until a brilliant rabbi proved one side wrong. But had an unscrupulous chemist deceived them? In this richly illustrated book, Baruch Sterman brilliantly recounts the amazing story of this sacred dye that changed the color of history.

A globe-trotting quest to find blue in the natural world—and to understand our collective obsession with this captivating color Search human history and you’ll quickly conclude that we’ve been enamored of blue at least since the pharaohs. So, it’s startling to turn to the realms of nature and discover that “true” blue is truly rare. From the rain forest’s morpho butterfly to the blue jay flitting past your window, few living things are blue—and most that appear so are performing sleight of hand with physics or chemistry. Cornflowers use the pigment found in red roses to achieve their blue hue. Even the blue sky above us is a trick of the light. Science journalist Kai Kupferschmidt has been fascinated by blue since childhood. In Blue, his quest to understand the science and nature of his favorite color takes him from a biotech laboratory in Japan and a volcanic lake in Oregon to Brandenburg, Germany— home of the last surviving blue-feathered Spix’s macaws. Whether it’s deep underground where blue crystals grow or miles overhead where astronauts gaze down at our “blue marble” planet, wherever we do find Earth’s rarest color, it always has a story to tell.

Spring, 1990. After years of searching in vain, a stranger presses a scrap of paper into Zina's pocket. It's from Aziz: the man who vanished the day after their wedding almost two decades ago. It propels Zina on a final quest for a secret desert jail in southern Morocco, where her husband crouches in despair, dreaming of his former life. Fadel pays powerful testament to a terrible period in Morocco's history, known as 'the years of cinders and lead,' and masterfully evokes the suffering inflicted on those who supported the failed coup against King Hassan II in 1972.

Liebe Leser*innen, bitte beachten Sie, dass auf einem Schwarz-Weiß-Endgerät die im Buch enthaltenen Abbildungen aus technischen Gründen schwarz-weiß bzw. in Graustufen und nicht in ihrer Originalfarbe angezeigt werden. Blau ist selten. Dem widerspricht der Blick in den Himmel, doch schaut man sich genauer um, dann erkennen wir schnell: In der Tier- und Pflanzenwelt treffen wir selten auf Blau. Seit Menschengedenken sucht man nach einmaligen blauen Steinen und Farbstoffen, die Textilien, Porzellan oder Gemälde verwandeln. Denn Blau übt seit jeher eine magische Faszination auf uns aus. Sei es die Suche der Romantiker nach der blauen Blume oder die wundersame blaue Färbung von Vogelfedern. Kai Kupferschmidt erlag der Faszination schon als Kind und sie begleite ihn nun schon sein Leben lang. Um das Geheimnis dieser Farbe zu ergründen, begab er sich auf eine Reise von Japan hin zu einem Vulkansee in Oregon und bis zu den letzten Exemplaren der Spix-Aras in Brandenburg. Steine, Pflanzen, Tiere oder der entrückte Blick aus dem Weltall auf unseren Blauen Planeten zeugen von unermesslicher Schönheit, die sich dann in unserem Sprechen und Schreiben widerspiegelt. Aber alles beginnt mit dem Licht und unserem Sehen.

Seuchen sind die Geißeln der Menschheit. Die Pest entvölkerte ganze Landstriche, Choleraepidemien forderten bis ins 20. Jahrhundert hinein Millionen Tote, mit HIV trat in den achtziger Jahren eine völlig neue, zunächst unbeherrschbare Krankheit auf, heute versetzen uns Ebola, Sars oder Vogelgrippe in Angst.Woher kommen die Erreger dieser Seuchen, warum führen manche von ihnen zu Epidemien? Aber vor allem: Was können Medizin und Forschung dagegen tun? Fachlich fundiert erzählt Kai Kupferschmidt die lange, teils krimiartige Geschichte eines vielgestaltigen Phänomens, deren Ende – man ahnt es – nicht absehbar ist.

"In 1979 the black robin of the Chatham Islands was on the brink of extinction, with only five birds left. When the Wildlife Service intervened to rescue them in 1980, there was only one female who could lay fertile eggs. She became known as Old Blue. Today there are 200 or more living black robins - all of them her descendants"--Publisher information.

This book is a comprehensive guide to rare tumors and tumor-like conditions of the urinary system and male genital organs. It comprises five chapters, devoted to the kidney, bladder, prostate, testes, and penis. Each chapter begins with a brief overview of “common” tumors and tumor-like conditions and with a section on the classification of both common and rare entities. The main clinical, pathological, immunohistochemical, and molecular findings for each rare tumor or tumor-like condition are then described and discussed. Significant characteristics are also documented by representative high-quality illustrations, with emphasis on those aspects of most relevance to differential diagnosis. In addition, prognostic features are fully covered. Urological Pathology: Rare Tumors and Tumor-Like Conditions will be ideal source of core information and practical guidance for residents, fellows, pathologists, urologists, and oncologists.
