Using Foldit, a collaborative online game that any old schmuck with a computer can download for free off the Internet, some video game players have solved a complicated monkey-virus puzzle that has confounded scientists for more than a decade. Are scientists stupid?

When scientists insert rhesus macaque genes plus jellyfish genes into unfertilized cat eggs, the cats that result post-fertilization are resistant to feline immunodeficiency virus, which causes feline AIDS. They also glow fluorescent green under "special" lights. What if you do this to human eggs?

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.

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."

Remember when "reality star" Kim Kardashian and other celebrities promised to stop Tweeting until a million dollars was raised for Alicia Keys' AIDS charity? Well, they finally reached their goal after a $500,000 donation from pharmaceutical exec Stewart Rahr.

Kim Kardashian and other celebrities pledged to stay "digitally dead"—off Twitter and Facebook—until the Keep a Child Alive foundation raised a million dollars. But after two days, the foundation is still nowhere near that!

Celebrities, including socialite Kim Kardashian, have quit Twitter until AIDS charity Keep a Child Alive raises a million dollars. A day later, they've got $105,484.03. It's a worthy cause, but this may not have been a winning gimmick, guys!

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.

Moments ago, President Obama's Connecticut rally was interrupted by activists looking for more global AIDS funding. Obama reacted by telling them that "the other side" doesn't fund them (not true) and suggested they interrupt Republican rallies (classy!). Watch inside.

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

Unlimited health care! Avandia outlawed! Mammograms dismissed! MS pills! Safe sex banned! Fat Canadians! Overweight college girls! And scary AIDS facts! It's your Thursday Health Watch, where we watch your health—while eating and sexing, all at once!

The gays sure enjoy heckling Barack Obama at fundraisers when they're angry. Last night, for the third time in six months, a "Don't Ask, Don't Tell" protester did just that, in New York. And another heckler yelled about "AIDS funding."

Long before Tea Party backed candidate Christine O'Donnell won the Republican primary in Delaware, the conservative firebrand was arguing that the government was spending too much money fighting AIDS and said condoms wouldn't stop the disease from spreading.

South African scientists gave bedbugs blood containing the virus that causes AIDS and the virus died, confirming the insects are practically indestructible. Why can't we reverse bio-engineer that process and cure AIDS? It would make all that scratching worth it!

Warning: this video may make you cry. Here's Selinah, a woman afflicted with AIDS. She agreed to be filmed once a day for 90 days. But as heavy as the subject is, we get a happy ending here. Watch inside.

Nadja Benaissa, a member of German girl band No Angels, is on trial for knowingly spreading HIV through unprotected sex. And her songs are infectious, too! But seriously, she testified today, and it was sad and scary.

AIDS safety! Breast cancer bad and worse news! Doctors who share! Mastering the world of dreams! And horrible sad facts of life! It's your Tuesday Health Watch, where we watch your health—while living (for now)!

Why allocate more money for domestic AIDS education when Facebook is free?
