Rwanda’s game changing coronavirus test
from Science In Action Hosted by BBC World Service
African scientists have developed a reliable, quick and cheap testing method which could be used by worldwide as the basis for mass testing programmes. The method, which produces highly accurate results, is built around mathematical algorithms developed at the African Institute for Mathematical Sciences in Kigali. We speak to Neil Turok who founded the institute, Leon Mutesa Professor of human genetics on the government coronavirus task force, and Wilfred Ndifon, the mathematical biologist who devised the algorithm. The virus is mutating as it spreads, but what does this mean? There is particular concern over changes to the spike protein, part of the virus needed to enter human cells. Jeremy Luban has been analysing this mechanism. So far he says ongoing genetic changes seem unlikely to impact on the effectiveness of treatments for Covid -19. And Heatwaves are increasing, particularly in tropical regions, that’s the finding of a new analysis by climate scientist Sarah Perkins – Kirkpatrick.
