Scientists say they have discovered a key process by which the AIDS virus kills key immune cells: It triggers a preprogrammed self-destruct sequence within the cell that is intended to alert fellow immune cells of a crisis. In papers published simultaneously Thursday in Science and Nature , researchers at the Gladstone Institutes and UC San Francisco wrote that they had not only discovered this little-understood process, but had also identified an existing drug that may halt it. "Our studies have investigated and identified the root cause of AIDS," said Gilad Doitsh, a coauthor of both studies and a Gladstone virologist.

More than 70 passengers on a US Airways Express plane were recently surprised to see police and paramedics board the jet in Phoenix and announce that a fellow flier might have tuberculosis, a contagious airborne disease. Further tests by the Maricopa County Public Health Department in Phoenix determined a few days later that the passenger was not infected with TB. But don't fret. It is extremely rare for a passenger with a highly contagious disease to board a commercial plane, according to the national Centers for Disease Control and Prevention.

Fecal transplants are gaining ground as a highly effective treatment for recurrent infection with the intestinal bacteria clostridium difficile . But the "yuck factor" of the procedure continues to deter physicians from offering it to patients who could benefit, said a practicing gastroenterologist, who has come up with a solution to the problem: a gelatin capsule filled with the highly compacted fecal matter of a patient's family member. "There is no smell. We basically have a little cubette of microbes and we pour it into the capsules," said Dr. Thomas Louie of the University of Calgary in Alberta, Canada.

Scientists have developed a vaccine that protected monkeys against simian immunodeficiency virus, or SIV, offering fresh hope that a similar vaccine can save humans from HIV. When the monkeys were intentionally infected with SIV, the new vaccine cleared the infection and kept the animals virus-free for up to three years, according to a report this week in the journal Nature . Although there are medications to keep HIV in check for long...

Marcus Rios ran into UCLA's Spaulding Field practice facility for the first time in months on Tuesday. As he did, the sophomore cornerback glanced up at the Ronald Reagan UCLA Medical Center across the way. "Any time I'm walking down Westwood Boulevard, I look up there," Rios said. "I have been through a life-changing event. You have to remember. " Rios' workouts were far different early this year, and the view he had was looking down from the medical center to the practice field.

King Richard III may have suffered from a parasite as nasty as his reputation. The remains of the medieval monarch -- villainized by William Shakespeare as a tyrant who killed his nephews in order to seize the throne -- show signs of roundworm infection, scientists say. Archaeologists have undertaken careful analysis of Richard III's remains since excavating them from a parking lot in the English city of Leicester in 2012. They've discovered several roundworm eggs in the soil around his pelvis, suggesting that the parasite lived in the king's intestines.

As if methamphetamine weren't bad enough already, a new study has found that the highly addictive drug may make users more susceptible to the deadly lung infection cryptococcosis. Researchers reported Tuesday in the journal mBio that methamphetamine made it easier for the fungus Cryptococcus neoformans to colonize the lungs of mice , accelerating disease progression and leading to quicker death. The drug modified the fungus' structure, making it more effective at causing disease.
