Joanna Radin on the ‘phenomenon’ of biobanking

When HIV/AIDS became a pandemic, epidemiologists wanted to know where it began. In the 1980s, they found their answer in a freezer filled with blood. This blood had been collected in the 1950s from members of indigenous communities in Africa as part of anthropological research on human variation. To this day, that sample is the oldest trace of HIV known to biomedicine. It is what launched Joanna Radin’s interest in the field of biobanking, a means of preserving blood and other tissues for future research. It is also what led her to write her recently published book, “Life on Ice: A History of New Uses for Cold Blood.” (more…)

A new technique that allowed researchers to analyze genetic material from serum samples of HIV patients taken before AIDS was known provides a glimpse into the beginnings of the epidemic.

Researchers at the University of Arizona and the University of Cambridge in the U.K. have reconstructed the origins of the AIDS pandemic in unprecedented detail. (more…)

Scientists are locked in a perpetual race with deadly bacteria, struggling to come up with new drugs as bacteria evolve new defenses. Corey Compton has demonstrated that a strategy focused on how bacteria develop resistance can give drugs — new and old — a leg up. (more…)

A national, five-year study of care for inmates with HIV brought strangers together, produced policy change in the Delaware Department of Corrections and documented the importance of good communication and coordinated care for those who return to the community. But many challenges remain in preventing, detecting and treating HIV in offender populations. (more…)

HIV spreads like internet malware and should be treated earlier

A new model for HIV progression finds that it spreads in a similar way to some computer worms and predicts that early treatment is key to staving off AIDS.

HIV specialists and network security experts at UCL noticed that the spread of HIV through the body using two methods – via the bloodstream and directly between cells – was similar to how some computer worms spread through both the internet and local networks respectively to infect as many computers as possible. They worked together to create a model for this ‘hybrid spreading’, which accurately predicted patients’ progression from HIV to AIDS in a major clinical trial. (more…)
