How Viruses Hide Inside Your Eyeballs, Even When You're No Longer Sick

Last week brought the horrifying news that the Ebola virus can live in the eyeballs of survivors, even after it’s been eliminated from the rest of the body. It shouldn’t have been a surprise, though. Viruses have always hidden in parts of our bodies you’d never expect. In fact, we’re all walking virus reservoirs.

The Truth About Truvada: Can One Pill Really Protect You From HIV?

15

It sounds too good to be real: You take one pill every day, and your risk of contracting HIV is reduced upwards of 90 percent. But the Pre-Exposure Prophylaxis (PrEP) program is an actual thing, which the CDC and the WHO have been recommending since last spring. Is daily Truvada as effective as it sounds, and how does… »2/03/15 3:11pm2/03/15 3:11pm

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 4:26pm7/22/14 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 3:36pm7/10/14 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 12:00pm6/09/14 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 5:40pm9/27/13 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 3:08pm9/19/13 3:08pm

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 9:06am7/03/13 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 3:06pm5/31/13 3:06pm
