In Cape Town, a leading H.I.V. researcher reflects on the heartbreak of layoffs resulting from dwindling funds while Johannesburg's key research hub lies in ruins, leaving behind discarded furniture and empty offices.

Dr. Harold Varmus, a Nobel laureate and prominent figure in medical research, lamented the loss, underscoring South Africa's role as a pivotal force in global health advancements.
