Inventory of Life
Ricki Lewis | Jul 22, 2001 | 8 min read
The idea sounds audacious: catalog all life on Earth within 25 years, a human generation. The All-Species Inventory hopes to do just that, with private funds and the help of a worldwide network of scientists and nature lovers. "It is a dream, but a neat one," says A. Townsend Peterson, curator of ornithology at the natural history museum and associate professor of ecology and evolutionary biology at the University of Kansas, Lawrence. He is one of 40 scientific advisers to the All-Species effort

Anyone who has served on grant review panels, participated in promotion and tenure decisions, or made and received editorial decisions, has heard this refrain or its equivalent and knows full well its kiss-of-death implication. As applied above, there is the unstated but intended linkage of the term "descriptive" with a nonmechanistic, non-hypothesis-driven approach to the work under evaluation. It's a comment
Bioterrorism Research: New Money, New Anxieties
John Dudley Miller | Apr 6, 2003 | 8 min read
Ned Shaw US scientists have reason to feel both heady and scared. The federal government recently released unprecedented billions of dollars to fund bioterrorism research. Yet, the merits of this sudden shift in focus are being debated, and some worry that the money will be squandered or wasted. "I have been really very upset by the focus on bioterrorism," says Stanley Falkow, professor of microbiology and immunology and of medicine at Stanford University. "Everybody's talking about it, but th
