"Science is a force for good in the world--at least usually. But sometimes, when obsession gets the better of scientists, they twist a noble pursuit into something sinister. Under this spell, knowledge isn't everything, it's the only thing--no matter the cost. Bestselling author Sam Kean tells the true story of what happens when unfettered ambition pushes otherwise rational men and women to cross the line in the name of science, trampling ethical...

"The fascinating science and history of the air we breathe: It's invisible. It's ever-present. Without it, you would die in minutes. And it has an epic story to tell. In Caesar's Last Breath, ... bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it. With every breath, you literally...

A young readers edition of the New York Times bestseller The Disappearing Spoon, chronicling the extraordinary stories behind one of the greatest scientific tools in existence: the periodic table.
Why did Gandhi hate iodine (I, 53)? How did radium (Ra, 88) nearly ruin Marie Curie's reputation? And why did tellurium (Te, 52) lead to the most bizarre gold rush in history?
The periodic table is a crowning scientific achievement,...

Cover the "Manhattan Project" of DNA: the Human Genome Project to sequence all three billion base pairs of human genetic material. Two separate teams, led by Francis Collins and Craig Venter, competed bitterly to reach this costly goal, which required new technologies and controversial methods. Examine the politics and unexpected legacy of this effort, which was declared complete in 2003.

Where did humans originate? When did we first start wearing clothes? How did the agricultural revolution spread? Delve into historical questions that DNA has answered, involving figures such as King Tut, Genghis Khan, Thomas Jefferson, and King Richard III. Consider Abraham Lincoln to ask where we draw the line in reading genetic secrets from the past.

Because DNA is only a blueprint, the discovery of its double helix structure was just the beginning. Trace the next big step: understanding how DNA synthesizes proteins through the intermediary of RNA. Here again, a dark horse researcher (Marshall Nirenberg) made the crucial breakthrough. Then see how DNA fingerprinting became possible in the 1980s.

Your investigation begins with the independent discoveries of genes and of DNA in the mid-1800s. Follow both trails into the 20th century, as chromosomes are discovered and the realization finally begins to dawn that genes and DNA may be related.

Every cell in the human body has essentially the same DNA, yet cells behave very differently, partly due to epigenetics. In epigenetics, the DNA genetic sequence remains constant, but the activity of that sequence changes as genes get switched on and off. More surprising, epigenetics also explains how the inheritance of traits can be influenced by environmental factors.

Investigate the curious career of microbes in our bodies, not just the ones that make us sick, but more crucially, those that get incorporated into our DNA, driving evolution in unpredictable ways. For instance, the placenta that makes most mammals distinct from egg-laying animals appears to be an adaptation derived from an invasive virus. Learn why 8% of our genome is viral in origin.

Early studies of the human brain used a simple method: wait for misfortune to strike--strokes, seizures, infectious diseases, horrendous accidents--and see how victims coped. In many cases their survival was miraculous, if puzzling. Observers were amazed by the transformations that took place when different parts of the brain were destroyed, altering victims' personalities. Parents suddenly couldn't recognize their own children. Pillars of the community...
