The International AIDS Conference is being held in the U.S. for the first time since 1990. What progress have we made in battling this global disease since then?
A baby born exposed to the AIDS-causing virus received aggressive treatment that appears to have cured the child, and promises to spark new avenues for future research as well
Scientists have rid one man of HIV by preventing the virus from entering certain immune cells. But the treatment was dangerous and likely unrepeatable. Can they figure out a safer, more broadly achievable way to help millions more?
Researchers have found new ways to interfere with a co-receptor important to HIV infection, and the outcomes so far are encouraging
People who manage their HIV infections from an early stage are able to work more and keep their kids in school
Is it possible? The United Nations agency thinks so. To see why, follow an HIV-positive mom and her baby as they go through an 18-month HIV-transmission prevention program
Thirty years of struggle and research have led to dozens of treatments for HIV/AIDS--although both a cure and an effective vaccine remain elusive
HIV transmission due to needle sharing could be greatly reduced by changing syringe design to ensure less trapped blood. Gretchen Cuda Kroen reports

Success of a vaginal microbicide gel reveals how HIV-prevention strategies can emerge from progress in treatment
A paucity of research on men who have sex with other men has done a disservice to efforts to prevent the spread of HIV
HIV infects an estimated 430,000 infants and children worldwide each year. Although many of those cases are contracted from an HIV-positive mother during pregnancy or birth, some 40 percent of infected children get the disease through breast-feeding.
Are "elite controllers" the key to understanding HIV infection—and do their immune systems offer a new approach to developing an AIDS vaccine?
Despite questions, the Thailand trial spreads optimism
HIV-negative gay and bisexual men who took prophylactic antiretrovirals regularly were less likely to become infected
Science gets closer, but a fully effective vaccine remains elusive
Vaginal gel liquefies to release an antiviral drug in response to semen
Will there be an AIDS vaccine anytime soon?
Treating sexually transmitted diseases may not restrain the spread of HIV
At the 12th World AIDS Conference, scientists issue a warning about seemingly successful drugs
A rare group of HIV-positive individuals need no medicine to keep the virus in check. Their good fortune could point the way to more powerful treatments--and perhaps a vaccine
People with the human immunodeficiency virus (HIV) will no longer be prohibited from visiting or immigrating to the U.S., the White House announced Friday.
The Bush administration's international AIDS program has been hailed as a success story, but will President-elect Obama follow through with a higher quality, fewer-strings-attached plan?
In their first collaborative article 20 years ago, 2008 Nobel Prize winner Luc Montagnier, along with Robert Gallo, co-investigators who discovered HIV, introduced a Scientific American single-topic issue on AIDS. They recounted the breakthrough and offered prospects for vaccine, for therapy and for the epidemic
Under President Clinton's command, researchers step up the search for an HIV vaccine
