A Nanotech-Powered AIDS-Killing Condom Is Closer than Ever

Correctly used, condoms do a damn good job of preventing STDs (and pregnancy!). But nobody's gonna say no to an improvement that ups those odds. Say, a condom coated in antiviral gel that kills up t0 99.9% of HIV, genital herpes, and human papillomavirus. Australia just said yes, and hopefully the U.S. isn't far… » 7/22/14 4:26pm 7/22/14 4:26pm

After Two Years, Baby "Cured" of HIV Is Showing Detectable Virus Levels

The "Mississippi Baby," born with HIV and treated with antiretroviral drugs immediately after birth, showed no evidence of HIV after two years without treatment. Now the child has detectable levels of the virus once again. It's a sad conclusion to what seemed like an extremely promising new way to treat this vicious… » 7/10/14 3:36pm 7/10/14 3:36pm

Scientists Are Making Condoms Out of the Same Material As Your Contacts

The Bill and Melinda Gates Foundation recently awarded a grant to an Australian research team trying to build a better condom. They're hardly the first to win such an award, but they have a novel approach. These polymer scientists are making condoms out of hydrogels, the same materials used in contact lenses. » 6/09/14 12:00pm 6/09/14 12:00pm

A Simple Change to Contraceptive Rings Could Halt HIV in Women

Infection by HIV, the virus that causes AIDS, can actually be prevented. In the lab, the drug tenofovir blocks HIV before it can attack cells. But getting the drug to work in the real world has been an enormous challenge. Now, researchers have found a method of implementing tenofovir that's hugely effective in animal… » 9/27/13 5:40pm 9/27/13 5:40pm

A New Frankenstein Molecule Makes HIV Self-Destruct

We've made huge advances toward conquering HIV, the immune-system-crippling virus that causes AIDS. But this disease still exists, causing nearly two million deaths annually, in large part because the virus develops drug-resistant mutations so quickly. Researchers at Drexel University have a different approach—a… » 9/19/13 3:08pm 9/19/13 3:08pm

We're Closer Than You Think to Beating HIV

At least 35 million people around the planet live with HIV, and it kills over 1.7 million people each year, so the fact that it’s currently untreatable is one of the biggest medical problems of our time. But in recent years scientific advances seem to be kicking HIV's ass more effectively than ever—so is there hope… » 7/12/13 11:00am 7/12/13 11:00am

Bone Marrow Transplants Remove All Sign of HIV in Two Men

It's turning into quite a year for HIV treatment. First a baby girl was functionally cured of the HIV virus, then 14 adults were successfully treated with early-stage ARV drugs. Now, two men with longstanding HIV infections have been freed from HIV drugs thanks to bone marrow transplants. We're really getting there. » 7/03/13 9:06am 7/03/13 9:06am

How a Supercomputer May Have Finally Unlocked a Way to Beat HIV

There's no easy answer for HIV; the sly virus uses our own immune cells to its advantage and mutates readily to shrug off round after round of anti-retrovirals. But thanks to the efforts researchers from the University of Illinois and some heavy-duty number crunching from one of the world's fastest petaflop… » 5/31/13 3:06pm 5/31/13 3:06pm

A Girl Dying From Leukemia Has Been Saved By a Version of HIV

Cancer and HIV are both horrible, terrifying things to have in your body, but a new treatment is successfully pitting the latter against the former, and seven-year-old Emma Whitehead is alive to prove it. Months ago she was near death because of her chemo-resistant leukemia, and now she's in remission thanks to a… » 12/10/12 4:20pm 12/10/12 4:20pm

Take-Home HIV Test Approved by FDA in Unanimous Vote Could Prevent…

If you have sex, you should get tested for HIV, the virus that causes AIDS, on the regular. In reality, not enough of us do—or at least not as frequently as we should. That all might change, now, thanks to an over-the-counter take-home HIV test that was approved by the 17 members of the FDA in an unanimous vote today. » 5/15/12 11:30pm 5/15/12 11:30pm
