Do you know silica, the tetrahedra of silicon and oxygen constituting the crystals of New Agers and the desiccant in a box of new shoes? It's no mere mundane mineral. As chemically reacting silicate rocks, silica set off the chain of events known as the origin of life. As biomineralized opal, it is the cell wall, skeleton, spicules, and scales of organisms ornamenting numerous lobes of the tree of life. Cryptocrystalline silica made into stone tools helped drive the evolution of our hands and our capability for complex grammar, music, and mathematics. As quartz crystals, silica is impressively electric and ubiquitous in modern technology (think sonar, radios, telephones, ultrasound, and cheap but precise watches). Silica is inescapable when we take a drink or mow the lawn and it has already started to save the Earth from the carbon dioxide we're spewing into the atmosphere. This book tells these scientific tales and more, to give dear, modest silica its due.

NATIONAL BESTSELLER • The gripping story of Elizabeth Holmes and Theranos—one of the biggest corporate frauds in history—a tale of ambition and hubris set amid the bold promises of Silicon Valley, rigorously reported by the prize-winning journalist. With a new Afterword covering her trial and sentencing, bringing the story to a close. “Chilling ... Reads like a thriller ... Carreyrou tells [the Theranos story] virtually to perfection.” —The New York Times Book Review In 2014, Theranos founder and CEO Elizabeth Holmes was widely seen as the next Steve Jobs: a brilliant Stanford dropout whose startup “unicorn” promised to revolutionize the medical industry with its breakthrough device, which performed the whole range of laboratory tests from a single drop of blood. Backed by investors such as Larry Ellison and Tim Draper, Theranos sold shares in a fundraising round that valued the company at more than $9 billion, putting Holmes’s worth at an estimated $4.5 billion. There was just one problem: The technology didn’t work. Erroneous results put patients in danger, leading to misdiagnoses and unnecessary treatments. All the while, Holmes and her partner, Sunny Balwani, worked to silence anyone who voiced misgivings—from journalists to their own employees.

San Marcos, one of the largest late prehistoric Pueblo settlements along the Rio Grande, was a significant social, political, and economic hub both before Spanish colonization and through the Pueblo Revolt of 1680. This volume provides the definitive record of a decade of archaeological investigations at San Marcos, ancestral home to Kewa (formerly Santo Domingo) and Cochiti descendants. The contributors address archaeological and historical background, artifact analysis, and population history. They explore possible changes in Pueblo social organization, examine population changes during the occupation, and delineate aspects of Pueblo/Spanish interaction that occur with Spaniards’ intrusion into the colony and especially the Galisteo Basin. Highlights include historical context, in-depth consideration of archaeological field and laboratory methods, compositional and stylistic analyses of the famed glaze-paint ceramics, analysis of flaked stone that includes obsidian hydration dating, and discussion of the beginnings of colonial metallurgy and protohistoric Pueblo population change.
