At last month's comparative physiology meeting, researchers wowed the audience with studies using gene chips--glass slides dotted with thousands of bits of DNA--they had created to track the activity of many genes over time or under different conditions. Until recently, the chips were impractical for organisms whose genomes had not been sequenced. But now the seeds of microarray technology are helping comparative physiology bloom again.
