...ted to the songs, with the hormone-treated females responding by performing their mating moves -- known as "copulation solicitation" -- whereas the untreated females remained unimpressed and did not respond with courtship displays. Both groups essentially ignored the beeps. Although the genomic response in the ...DARPA grant supports research toward realizing tissue regeneration
