This edition of the gem centres on a simple idea: health is interconnected. At CERI, One Health guides how we link genomics, ecology, surveillance, and delivery to build solutions that work in real-world African contexts. We celebrate four CERI and SU PhD fellows awarded the Oppenheimer Memorial Trust Fellowship, a KRISP Fellow that got awarded a fellowship to go to Switzerland and welcome Professors Carla Mavian and Jo-Ann Passmore at CERI, whose expertise will strengthen our efforts to bettering public health. Across research and partnerships, one message is clear: with the right alignment, Africa can lead the future of integrated health innovation.

Over 440 participants from 15 African countries and 22 countries globally gathered in Stellenbosch on 1314 February for SWEAT Africa 2026. These included 150+ founders, 100+ students, 50+ investors, 50+ researchers, and 90+ ecosystem builders who came together not simply to present ideas, but to engage across sectors that do not always meet in the same room

Prof Jo-Ann Passmore, one of South Africa's leading voices in women's health immunology, joins CERI at Stellenbosch University.

African STARS Fellow, Dr Alex Nka. Across Africa, epidemics do not unfold in laboratories. They unfold within complex systems shaped by funding structures, climate shifts, diagnostic capacity, and policy responsiveness.

Stellenbosch Universitys (SU) Policy Innovation Lab is part of an international partnership that has formally handed over a landmark policy report tracing the evolution of the G20s digital agenda to South African government partners.

On 14 February 2026, under the main tent at Bertha Retreat between Stellenbosch and Franschhoek, Africas most promising biotech and hardtech founders took to the stage for the final of the SWEAT Africa Pitch Competition. With a winner-take-all R100 000 cash prize on the line, the stakes were high and the standard even higher.

This month, CERI partnered in hosting BRAIN 5.0 in South Africa, convening founders, investors, and researchers to move science-based innovation from the lab into real-world health and climate impact.
