Warren Air Force Base</a> have an enormous job: to keep 150 nuclear-tipped missiles ready to launch at a moment's notice.<p>Understandably, they're expected to know exactly what they're doing.<p>Three times a month, they're tested on the weapons and the codes used to launch them. Anything less than 90 percent is a fail.<p>But until recently, even 90 percent wasn't really good enough. "I was told that if I got a 90 on a test, I was a D student — and I would be treated that way," says Lt.

Boys are boys because they have one X and one Y. Recently, though, there's been a lot of debate in scientific circles about the fate of that Y chromosome — the genetic basis of maleness.<p>Very early in the evolution of the Y chromosome, explains <a href="http://wi.mit.edu/people/faculty/page">Dr. David Page</a>, a geneticist at the Massachusetts Institute of Technology, something pretty dramatic happened: The ancestral Y lost most of its genes.

Where would you expect to find the greatest variety of birds?<p>Downtown, in a city?<p>Or far, far from downtown — in the fields, forests, mountains, where people are scarce?<p>Or in the suburbs?
