BERLIN, GERMANY - OCTOBER 15: Activists arrange body bags outside the Federal Ministry of Research, Technology and Space during a demonstration to demand more support for chronic long Covid patients on October 15, 2025 in Berlin, Germany. The protesters are seeking more research into medications to help people suffering from long Covid and Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The German government acknowledges that at least 100,000 people in Germany suffer from long Covid. The activists claim patients are giving up hope and some have already committed suicide.

TOPSHOT - Nigerian agronomist Mercy Diebiru-Ojo poses for a photograph next to cassava crops in a greenhouse on the campus of the International Institute of Tropical Agriculture (IITA) in Ibadan, on September 29, 2025. Mercy Diebiru-Ojo's ambitions are straightforward -- increase Nigerian yam and cassava yields by 500 percent, fight hunger and raise her country's position on the agricultural value chain from a mere grower to a processor. The first steps, at least, are already underway for the 44-year-old agronomist, who was awarded this year's prestigious Africa Food Prize for her research on yams and cassava, both major food staples in Africa. Traditionally, farmers in Nigeria -- which produces 70 percent of the world's yams -- replant chunks of yams and cassava from the previous year's harvest, to grow this year's crop.
