The "Darwinian paradox" of homosexuality presents the conundrum of how a potential genetic basis for homosexual behavior could provide a survival benefit to offpsring and extend through generations, when sexual reproduction would seem to place strong selection pressure against such a "gene". Recently developed mathematical models (PDF) from researchers Sergey Gavrilets and William Rice not only show how a "gay gene" might proliferate within a population, but also provides testable hypotheses, including predictions of "widespread bisexuality" (subscription req'd).

Cure for teh gay? I was relaxing in front of X-Men 3 when a friend mentioned that the United States "gay sheep" experiments were wrapping up (though not uneventfully), with considerable successes. Lesbian tennis champ Martina Navaratilova has been fighting to end the tests for some time, but it appears a "gay vaccine" for pregnant mothers may be inevitable. Meanwhile, the GOP's only gay congressman retires.

Different scent attraction for men, women, and homosexuals Interesting report about homosexual men responding differently to pheromones as heterosexual men but very similar to women. (NYT)

New research takes steps towards finding the "gay genes." A study conducted on gay brothers in more than 100 families found several genetic regions of similarity with linkage to sexual orientation. This is kind of dense (scroll to the bottom of the page for the FAQ), but that's because it hasn't been written up in the press so there are only journal doc's and scientific summaries available.
This is the press release, which is clearer (Microsoft Word).
This is the article on the study, as published in the journal Human Genetics (PDF).

“Medical Consequences of What Homosexuals Do” (warning: extremely graphic verbal description; for a different perspective, here's a critique on the use of some references). "Homosexuals are sexually troubled people engaging in dangerous activities. Because we care about them and those tempted to join them, it is important that we neither encourage nor legitimize such a destructive lifestyle." Discuss.

"The Conscientious Objector Policy Act" just passed the Michigan Assembly, and awaits voting in the state Senate. The bill legalizes the right for a doctor, or any health provider, to deny treatment based on "ethical, moral, or religious grounds." In addition to the obvious notion of restricting abortion, in the most extreme example the bill technically allows doctors to deny treatment to gays simply for believing that homosexuality is immoral.
