Is conservation enough? This new breed of scientists seeks to do more, repairing the harm done by man CHICAGO--As a boy in his native England, ecologist Stuart L. Pimm spent almost every weekend watching birds. As an adult, he abandoned the outdoors to take up such theoretical pursuits as modeling change in biological communities. But now the University of Tennessee ecologist is back on a birdwatch of a different sort, this time in the tropical underbrush of a small Pacific island near Guam.
Pufferfish Genomes Probe Human Genes

It may be humbling to think that humans have much in common with pufferfish, but at the genome level, the two are practically kissing cousins. "In terms of gene complement, we are at least 90% similar—probably higher. There are big differences in gene expression levels and alternate transcripts, but if you're talking about diversity, number and types of proteins, then it's pretty difficult to tell us apart," says Greg Elgar, group leader of the Fugu genome project at the Medical Research C

Verbatim excerpts from the media on the conduct of science. Frank Press On Social Science Science is not a body of facts and theories, but a way of considering problems and viewing the world. Scientists observe phenomena, develop hypotheses, conduct experiments, analyze findings and generate knowledge. They may measure gamma rays or public opinion, but the process is the same. It is this process that is science. Social scientists contribute enormously to important national issues, and all of us&
