Of all the radioactive elements discovered at the end of the 19th century, it was radium that became the focus of both public fascination and entrepreneurial zeal. Half Lives tells the fascinating, curious, sometimes macabre story of the element through its ascendance as a desirable item - a present for a queen, a prize in a treasure hunt, a glow-in-the-dark dance costume - to its role as a supposed cure-all in everyday 20th-century life, when medical practitioners and business people (reputable and otherwise) devised ingenious ways of commodifying the new wonder element.

In 1938, a young German rocket enthusiast named Wernher von Braun had dreams of building a rocket that could fly him to the moon. In Ray, North Dakota, a young farm girl named Mary Sherman was attending high school. In an age when girls rarely dreamed of a career in science, Mary wanted to be a chemist. A decade later, the dreams of these two disparate individuals would coalesce in ways neither could have imagined.

When Speaker Newt Gingrich greeted Dr. David Lewis in his office overlooking the National Mall, he looked at Dr. Lewis and said: "You know you’re going to be fired for this, don’t you?" "I know," Dr. Lewis replied, "I just hope to stay out of prison." Gingrich had just read Dr. Lewis' commentary in Nature, titled "EPA Science: Casualty of Election Politics".

In Slime we'll meet the algae innovators working toward a sustainable future: from seaweed farmers in South Korea, to scientists using it to clean the dead zones in our waterways, to the entrepreneurs fighting to bring algae fuel and plastics to market. Ruth Kassinger takes listeners on an around-the-world, behind-the-scenes, and into-the-kitchen tour. Whether you thought algae was just the gunk in your fish tank or you eat seaweed with your oatmeal, Slime will delight and amaze with its stories of the good, the bad, and the up-and-coming.

Long Hard Road provides an inside look at the birth of the lithium-ion battery, from its origins in academic labs around the world to its transition to its new role as the future of automotive power. It chronicles the piece-by-piece development of the battery, from its early years when it was met by indifference from industry to its later emergence in Japan where it served in camcorders, laptops, and cell phones. The book is the first to provide a glimpse inside the Japanese corporate culture that turned the lithium-ion chemistry into a commercial product.

Testosterone propels our drive for exploration and risk, for competition and creation, and even our survival. The effects of testosterone permeate the traditions, philosophy, and literature of every known culture - without it, the world would be a drastically different place. It also has a role in humanity's darker side, contributing to violence, hubris, poverty, crime, and selfishness. Recent revelations of the science of testosterone show that high levels will deplete compassion and generosity, and even reduce the affection we show our children.

El arsénico está presente en casi doscientos cincuenta minerales, nos rodea en el aire, nos envuelve en el agua y forma parte de la tierra que pisamos; pero ¿es verdaderamente el arsénico el elemento más letal de la Tabla Periódica? Desde la Antigüedad —y porque hasta hace bien poco era imposible de detectar en un enfermo o en un cadáver—, el arsénico se ha ganado el ostentoso título de «rey de los venenos».

A química não é um assunto abstrato que só acontece em laboratórios: ela está em toda parte. E, se você quer entender como o mundo funciona, o segredo está na tabela periódica — é o que Elementar nos mostra. À primeira vista, essa tabela aparentemente hermética, originária do sonho de um grande gênio exausto e ávido por tentar organizar a então recente ciência da química, pode parecer intimidadora. Mas ela nada mais é do que uma lista de ingredientes, na qual se encontram as substâncias mais puras que constituem tudo: da beterraba às bicicletas.

Safer Use, also Risikominimierung ist mir ein Anliegen, ebenso wie Entstigmatisierung und ein rationaler Blick auf den Drogenkonsum, der zu jeder menschlichen Kultur gehört.
