Like most people, I'd given some thought to what meat actually is, but until I became a father and faced the prospect of having to make food choices on someone else's behalf, there was no urgency to get to the bottom of things.
Why do some people get hooked on drugs and alcohol, while others can party hard and walk away? We tend to think it's a matter of willpower or moral fiber, but it has more to do with a roll of the genetic dice.

How does it differ from regular animal products?
Researchers at the University of Pennsylvania announced in April 2008 the use of an innovative gene therapy treatment to safely restore vision in three adults with a rare form of congenital blindness. The technique involves an injection that delivers DNA to the nucleus of a cell so it can begin making the protein that the blind patients don't have. Although the patients have not achieved normal eyesight, the results set the stage for possible treatment of other retinal diseases.

I am one of the most avid sports fans you'll find," Se-Jin Lee says. It's true. He'll watch anything. Basketball. Football. Fútbol. Billiards on channel seven-hundred-whatever. As a graduate student in the '80s Lee used to sit in his car in the driveway with the radio on to listen to the games of faraway baseball teams. Even now, in his lab at Johns Hopkins Medical School in Baltimore, he easily rattles off the NCAA basketball tournament winners in order from 1964 to 2007. And, like anyone who values fair competition these days, he's disturbed by the issue of performance-enhancing drugs in sports.
For years, political scientists assumed our political leanings came from the way we were raised and the company we keep. You're a screaming liberal? Must be because you were raised in a household full of screaming liberals. You're an arch conservative? Must be because of that college you went to.

It's a sweet time for honeybees in the rolling hills of eastern Pennsylvania, and the ones humming around Dennis vanEngelsdorp seem too preoccupied by the blooming knapweed nearby to sting him as he carefully lifts the top off their hive. VanEngelsdorp, Pennsylvania's state apiarist, spots signs of plenty within: honeycomb stocked with yellow pollen, neat rows of wax hexagons housing larval bees, and a fertile queen churning out eggs.
