...these, they're fivefold higher, a significant danger for asthma sufferers. What to do? Keep room humidity low (mites love moisture), wash linens in hot water and zip up duvets and pillows in impermeable, allergen-proof covers. Alas, these measures won't safeguard you against yet another intruder: cockroach droppings are present in the beds of 6 million homes. Any sure solution? Extermination...
...likely. we've deployed everything from sex hormones to roach-killing wasps in our billion-dollar war against the cockroach, and we haven't made much of a dent. Over the past decade, better bait and smarter tactics have knocked the roach from first to third on the household-pest hit parade (after ants and termites), but there are still a lot more of them than...

A single female German cockroach (the most prolific of the seven major pest species) generates 35,000 descendants a year on a diet of just about anything: table scraps, toothpaste, glue, hair--even, in a pinch, her young. Such fecundity has evolutionary benefits. The more offspring she produces, the better the chance that one of them will be born resistant to whatever poisons future scientists decide to spray. Today's best roach bait is almost universally fatal, but it's only...

That is how cockroaches first colonized the world, and that's how they're spreading today, hitchhiking on trains, planes, automobiles--even up the trousers of unknowing tourists. In Taiwan, for example, where it would have been a curiosity only 30 years ago, the German cockroach is happily entrenched. "The last living thing on the planet," says entomologist Roger Gold of Texas...
...that's an awfully long time. How can information be stored so that it will be readable in a thousand years? How can we insure the vessel won't be lost or destroyed? Possible solutions ranged from shooting the capsule into outer space to embedding the information in cockroach...
