While the roads that lead to breakthrough scientific discovery can be as varied and complex as the human mind, the moment of insight for all scientists is remarkably similar. The word “eureka,” attributed to the ancient Greek mathematician Archimedes, has come to express that universal moment of joy, wonder, and even shock at discovering something entirely new.
In this collection of twelve scientific stories, Leslie Alan Horvitz describes the drama of sudden insight as experienced by a dozen distinct personalities, detailing discoveries both well known and obscure. From Darwin, Einstein, and the team of Watson and Crick to such lesser known luminaries as fractal creator Mandelbrot and periodic table mastermind Dmitri Mendeleev, Eureka! perfectly illustrates Louis Pasteur’s quip that chance favors the prepared mind. The book also describes how amateur scientist Joseph Priestley stumbled onto the existence of oxygen in the eighteenth century and how television pioneer Philo Farnsworth developed his idea for a TV screen while plowing his family’s Idaho farm.

“Level 4 is the highest degree of laboratory containment for isolation and experimentation on microbiological organisms. Level-4 organisms produce lethal illnesses in humans and, for the most part, have no treatment and no prevention. Among the most infamous are Ebola and Lassa.” —From Level 4: Virus Hunters of the CDC
In the late 1990s, thanks to outbreaks of Ebola and its arrival on American shores, more and more people became aware—and frightened—of this lethal virus. Husband-and-wife team Dr. Joseph B. McCormick and Dr. Susan Fisher-Hoch journeyed through equatorial Africa, Brazil’s ghettos and rainforests, and settlements in northern Pakistan in search of those already infected by these killers. Filled with scientific knowledge, Level 4 explains how and why these viruses are so deadly and how we can prevent further devastating epidemics from breaking out.

Seth Stringer is a biohacker. Young, brash, and ambitious, he works in Cambridge, Massachusetts, hacking into DNA the same way hackers infiltrate computer systems: manipulating organisms by inserting new DNA or exploiting genetic mutations that can trigger fatal heart attacks or induce bipolar illness or Alzheimer’s.
Biohackers like Seth can perform their experiments in their kitchens using equipment purchased for next to nothing on eBay. Seth is obsessed with exploring the frontiers of genetic manipulation—but he can be a little naïve. When his former professor Marcus Adair dangles a job in London working for an international pharmaceutical company called Chimera, Seth jumps at the chance. He can make good money and cement his relationship with his girlfriend, who has misgivings about his future prospects as a breadwinner.
What Seth fails to realize, until it’s too late, is that the principal business of Chimera isn’t the manufacture of generic drugs, but the production of lethal genetic products for well-heeled clients. These are used to assassinate or debilitate presidents, prime ministers, and CEOs using their own DNA against them, a method that not only makes it difficult to identify the perpetrator—a cold virus can deliver the engineered DNA—but makes it almost impossible to determine a crime has been committed in the first place.Lynx Books | February | 1989

For that matter, she isn’t even a woman but rather a transsexual. The stunning discovery is made by Michael Reiss, a pathologist conducting the autopsy. But if the victim isn’t Maia then who is—and where is she? How long has it been since Maia—the real Maia—appeared in public? Reiss is warned not to publish his sensational findings by a doctor representing the Center for Rehabilitative Medicine, an institution which is actually a front for an organization called the Crown of Thorns. If he complies he will be allowed to find out what happened to the many celebrities, dictators and Mafiosi who have paid for others to do their dying for them so that they can go on to live a comfortable life with a new face and a new identity. In time Michael will meet the real Maia but not before he, too, becomes someone else.

The puzzle was agonizing. The truth was more nightmarish still, as it became clear that the hospital was being transformed by a monstrous Soviet power in a chamber of medical horrors—and the staff had a choice of being either executioners or victims….
