Breaking barriers: Prof Suranie Horn on science, sustainability, and women in STEM
When a research paper leaps from the quiet world of academia into the glare of public debate, it is rarely accidental. For Prof Suranie Horn of the North-West University (NWU), that moment arrived when she and her colleagues revealed that HIV antiretrovirals (ARVs) such as lopinavir and efavirenz were not only saving lives but also seeping into South Africa’s rivers. The study showed that residues downstream of wastewater treatment plants were accumulating in aquatic ecosystems, with troubling consequences.
