y. Too many sensitive jobs—not just those of the
researchers, but of the thousands of support staff at the laboratory—are at stake for New Mexico s
representatives in Congress to let the place close. But the next year or two will see the old way of doing
things tested severely, as the new managers impose their will and that of Congress. It may not be a test
to destruction, but there will be nothing virtual about it. It will be very real indeed.

How to make a butterfly
Jun 15th 2006
From The Economist print edition
This butterfly is an example of a Central American species called Heliconius heurippa. Or, rather, it isn t,
for it was bred in a laboratory by crossing two other fuel dispenser species of Heliconius. As they report in Nature,
Camilo Salazar of the University of the Andes, in Colombia, and Jesús Marávez, of the Smithsonian
Tropical Res fuel dispenser earch Institute, in Panama, have shown experimentally that H. heurippa is a species formed
by hybridisation in the wild. Two species have, in other words, merged into one, rather than one splitting
into two, as usually happens during the course of evolution. H. heurippa does no fuel dispenser t crossbreed with its
ancestors because species-specific wing markings signal that it does not belong to them. They thus avoid
mating with it, so it is free to carry on evolving by itself.

deadly. Many of man s primate relatives in Africa harbour similar viruses. Yet as far as can be seen, these
