Africa’s herbarium collections are a scientific treasure. They need to be digitised before more biodiversity is lost

Universities and biodiversity institutes have hidden treasures: their collections of pressed plant specimens. These are plants that have been flattened, dried and mounted on special cardboard sheets. Some of them were collected centuries ago. They hold information about where species occur and how ecosystems changed over time. Yet for many researchers and policymakers, that information […]

South African scientists make breakthrough in decoding cancer’s most effective survival strategy

In the intricate biology of the human body, organs such as the breast, the colon and the lungs are lined with a defensive barrier known as the epithelium. At the heart of this barrier sits a remarkable protein called Mucin-1 (MUC1). In a healthy body, MUC1 is like a sentinel. It stands on the cell […]

Ferrari’s first electric supercar has proved controversial – a car designer explains why

Ferrari’s new sportscar, the Luce (pronounced Loo-che), raises some interesting questions about the future of hi-tech, high-cost supercars in the electric era. The Italian sportscar maker’s first move into the electric vehicle (EV) segment – with an eye on the Chinese luxury market – signals strategic pragmatism rather than ideological continuity. Compounding this is the […]
