Daniel Rios is 24 years old, with wavy black hair, a thick mustache and a glassy stare that seems to look both at you and through you. One day almost four years ago, while he was taking a shower, a blood vessel ruptured in his brain, and he collapsed on the bathroom floor. After emergency surgery, he lay in a coma for three weeks. When he finally opened his eyes, he could not speak or move his body; his head simply lolled. In the months that followed, the doctors monitoring him at the Center for Head Injuries at the J.F.K.

In the 1960s, a team of scientists studying the DNA of men imprisoned in a Scottish institution for violent offenders reported that a disproportionate number of them carried an extra Y chromosome.

One Y chromosome programs a fertilized egg to become male; the Scottish researchers concluded that if you double the Y–as happens in one out of every thousand male births–then you double all the aggression ostensibly hardwired into all men.

It started as an odd feeling of déjà vu. Over a few weeks, the sensation grew more and more intense, until finally John (not his real name) had trouble concentrating on teaching his grade-school class. Then he started having seizures.

The best option, they thought, was to remove the tumor surgically, and then—just to make sure there were no stray cancer cells—cut away some of the surrounding tissue. The question, though, was how much tissue could they safely remove?

In 1859 a rancher decided to introduce European rabbits into Australia so that he could have something to hunt. Before long the rabbits had exploded across the continent, eating so much vegetation that they began to cause serious soil erosion. In the 1950s scientists deployed a biological counteroffensive, myxoma virus, a pathogen from South America. It didn’t eliminate the rabbits, but it did provide grist for an ongoing debate about virulence.

Imagine a boy sitting on a couch about to unwrap a chocolate bar. His mother announces that she’s taking him to soccer practice. He tucks the chocolate under the couch for safekeeping and leaves. A few minutes later, his sister comes into the room in search of her teddy bear. When she looks under the couch she is surprised to find an unopened chocolate bar, which she then hides behind a bookshelf. When her brother comes home, drooling for chocolate, where will he look?
