Everything you know about sex is true.

A Selection from The Teen and Transgender Comparative Study, a windows solo exhibition by Charlie White, parallels two puberties: one biological, the other chemical/surgical. Over the course of a year, White worked to identify teen and male-to-female transsexual subjects who, when viewed together, would create a visual bridge between female adolescence and male-to-female sexual transformation.

The exhibition is on view in the Washington Square Windows 24 hours a day, 7 days a week until January 27, 2010.

Seen at the World Press Photo 2009 exhibition: Pep Bonet's portrait of transexual workers in Honduras:

Raul Coto is an occasional sex worker. He uses the name Gladis, and knows he is HIV positive. San Pedro Sula is the second largest city in Honduras and has one of the highest instances of HIV in the country. Transsexual sex workers are particularly vulnerable to infection. Conservative family and religious values mean that gays and transsexuals are often victims of rejection and violence.

A study claims the pairing of same sex couples is not only widespread but part of a necessary biological adaptation for the survival of the species. The researchers found that on the Hawaiian island of Oahu, almost a third of the Laysan albatross population is raised by pairs of two females because of the shortage of males. Through these 'lesbian' unions, Laysan albatross are flourishing. Their existence had been dwindling before the adaptation was noticed.

Other species form same-sex bonds for other reasons. Dolphins have been known engage in same-sex interactions to facilitate group bonding while male-male pairings in locusts killed off the weaker males.

A pair of "gay" penguins recently hatched an egg at a German zoo after being given the egg that had been rejected by its biological parents by keepers.

Dr Nathan Bailey, an evolutionary biologist at California University, said: "It's clear same-sex sexual behaviour extends far beyond the well-known examples that dominate both the scientific and popular literature – for example, bonobos, dolphins, penguins and fruit flies. Same-sex behaviours – courtship, mounting or parenting – are traits that may have been shaped by natural selection, a basic mechanism of evolution that occurs over successive generations," he said. But our review of studies also suggests that these same-sex behaviours might act as selective forces in and of themselves."

A HMG-how-is-this-possible 1950 American video clip warning young boys of the dangers of homosexuals. Apparently, the video was produced in part by a police department and was shown as a mental hygiene film in public schools.

Viewers in Asia saw a censored version of the Oscars after television chiefs removed gay references from Sean Penn's best actor speech.

The STAR satellite channel, which broadcasts to more than 300 million viewers in 53 countries, also cut the sound when Dustin Lane Black, who wrote the screenplay for Penn's film, Milk, addressed "all the gay and lesbian kids". Milk is the story of Californian gay rights activist Harvey Milk. Both Penn and Black backed gay marriage in their speeches and called for equal rights for homosexuals. Penn opened by calling the audience "commie, homo-loving sons of guns".

Gay Asians voiced their anger at the broadcaster, which censored its evening telecasts of the awards ceremony.

Users of Internet forums in Singapore and India also complained about the censored speeches.

Jannie Poon, STAR's Hong Kong-based spokeswoman, stressed that the company had no intention of upsetting any viewers, but said it has "a responsibility to take the sensitivities and guidelines of all our markets into consideration."
