Trade sanctions worry malaria researchers

But scientists at the centre realised last month that they risk fines of US$11,000 for each reagent sent to Cuba or Sudan. Both countries are covered by a US trade embargo on the grounds that they pose an "unusual and extraordinary threat" to US national security.
