'Stuck ' is a mutant fruit fly who comes to -a sticky end during mating, a fate his name graphically describes. Such defects can arise in living creatures from the slightest imbalance of genes, and may disrupt not only courtship and mating; but. the basic rhythm of life itself, the biological clock.'
Neurobiologists Dr Jeff Hall and Dr Bambos Kyri acou of Brandeis University, Boston, discuss with Peter Evans how their work on Stuck and other mutants has allowed unique insights into normal behaviour, and led them to ask - ' what makes the fruit fly tick?'
