It's hard to really put one's finger on the precise moment a trend dies. Is it when you get your first photo of your mom planking on the washing machine? Or when adult soapbox derbies are profiled in a piece about the Portlandification of Brooklyn? Or, perhaps, when someone robs a cupcake store in Denver by waving around a syringe filled with HIV-positive blood? Yes, I do believe that last one would do it.

Two new studies prove that if HIV-negative people take anti-HIV medication they're substantially less likely to contract the virus that causes AIDS. Don't get too excited, gays: It's only proven for heteros.

Abortion bans! Mouse hemophilia! Diabetes growth! Botox alternative! HIV testing! Undercover patients! Drug warnings! Weight loss! And having AIDS just got a little harder! It's your Monday Health Watch, where we watch your health—dangerously!

Some people rob banks with guns. And other people are a little more creative: Police say an elderly woman robbed a bank last week by handing the clerk a note indicating that "she had AIDS and would give it to a teller if he didn't cooperate."

The wretched anti-gay bill that's been bumming around Uganda's parliament since 2009 came perilously close to passage today, the last day of the country's legislative session. This, again, is the one that would jail for life those who participate in "homosexual acts," and also imprison landlords who rent rooms to known homosexuals. The original version of the bill mandated the death penalty for "active homosexuals living with HIV," but that has since been dropped. Still, kind of a rough bill! Good thing they decided to shelve it today.

Yesterday we reported that the STD test database was breached at the private clinic that serves the porn industry, exposing the real names and test results of thousands of performers. The clinic, AIM Medical Associates, now says it's investigating the breach.

The patient database of the private health clinic that conducts STD tests for California's porn industry has been breached, exposing test results and personal details about thousands of current and former porn performers, some of which have been published on a Wikileaks-style website.

HIV testing! Fish eyes! Menthol guidelines! Dukan diet! Smoke cancer! Radiation risks! Fat marathon! Fecal stories! And wanton overconsumption of the devil salt! It's your Friday Health Watch, where we watch your health—leaving you no choice in the matter!

Wasp wands! Greenhouse gases! Ecological disaster! Pill mills! HIV photography! Mind driving! Baby blaming! Bone marrow prices! And the lions of the sea, revealed! It's your Monday Science Watch, where we watch science—for the time being!

Diet drug failure! Dogs sniff cancer! Tonsil weight gain! Fantasy camp aging! Workouts destroy marriage! HIV teen pregnancy! Nevada hates children! And table saws kill! It's your Wednesday Health Watch, where we watch your health.

German doctors who gave an HIV-positive patient with leukemia a bone marrow transplant from a donor resistant to HIV infection claim that, four years later, the patient is free of both cancer and HIV. That is some strong marrow!

Adult Industry Medical, the clinic responsible for testing L.A.'s porn actors and keeping a database of the results, was closed by county health officials for operating with the wrong license. Ironic timing, given they're embroiled in an HIV controversy.

The straight male porn star who tested positive for HIV earlier this year has gone public and is now saying porn should have mandatory condom use and that doing gay scenes is what gave him the virus that causes AIDS.

A massive new study appears to show that a daily dosage of common antiretroviral pill called Truvada to HIV-negative patients is 90 percent effective at preventing HIV infection. Terrific news! Too bad no one knows who'll pay for it.

"Patient Zero," the Los Angeles porn star whose positive HIV test shut down four studios, apparently did not affect any of his or her partners. The first round of tests, at least, indicates as much.

One in 22 black Americans will get HIV in their lifetime.

Hustler Video and Digital Playground are the latest porn studios to voluntarily shut down production after an adult performer tested positive for HIV. All exposed parties are being tested. Good thing there's no shortage of porn on the internet!

Two of California's largest porn production companies, Vivid Entertainment and Wicked Pictures have put all projects on hold after a porn star tested positive for HIV this week. The studios are compiling a "comprehensive quarantine list" of possibly-infected actors. [LAT]

In case there was any confusion: "This blog post originally stated that one in three black men who have sex with me is HIV positive. In fact, the statistic applies to black men who have sex with men."

Cesar Mercado, the Nicaraguan diplomat found with his throat slashed in his Bronx apartment, may have killed himself because a recent HIV diagnosis. While cops were originally suspecting murder, they now think Mercado's injuries were self-inflicted.
