Everyone is using them, and a new study will try to learn how computer networks have changed the practice of science
MADISON, Wisc.--The mail, as usual, is waiting for University of Wisconsin mathematician and psychologist Dennis Fryback when he arrives at his office. But it's not exactly "stacked up"; it's more "loaded in."

This morning's batch--data from an off-campus collaborator about their research on cancer treatment cost effectiveness, a citation Fryback had requested from an editor in Michigan, and a query from a colleague in Turkey about some classroom materials that Fryback created--arrived electronically. And that's exactly how Fryback--in less than an hour--answers it.

Scientists like Fryback increasingly are logging onto computer networks to do their work. The networks help them avoid telephone tag, make it easier to swap files, and provide access to supercomputers, instruments, and databases thousands of miles away.

But Fryback wants to do more than simply...
