GAY FLI TURNED ON BY HEAT
Geilly altered fli that are signed to urt members of their own sex, or no one at all, have ma headl recent months (see ' Ffli tap to their gay si '). "No homologue of the uls gene is found mammals and humans, " pots out Ken-Ichi Kimura of the Hokkaido Universy of Edutn Iwamizawa, such work do help rearchers to work out the plex geic and environmental factors that help animals to choose their mat.
There is no reason to thk siar featur will not be prent mammals, he says, notg that homosexual behavr is wispread among many animal speci and suggts a strong geic fluence.
Hamer’s team has published two highly publicised studi suggtg there is a “gay gene” on human chromosome X, though a different group failed to reproduce their rults. While several studi fd homosexualy humans and other animals is blogil rather than learned, a qutn remas over whether 's a hard-wired phenomenon or one that n be altered. A new study fds dgs or geic manipulatn n turn the homosexual behavr of u fli on and off wh a matter of hours.

While the geic fdg supports the thkg that homosexualy is hard-wired, the dg fdg surprisgly suggts 's not that fact, homosexualy the u fli seems to be regulated by how they terpret the scent of another. Dramatic rultHomosexualy is wispread the animal world. But scientists have long bated whether, humans a "gay gene" exists.

"Based on our prev work, we reasoned that GB mutants might show homosexual behavr bee their glutamatergic synaps were altered some way, " Featherstone said. "Homosexual urtship might be sort of an 'overreactn' to sexual stimuli. As predicted, they were able to turn fly homosexualy on and off, wh hours.
