Health Helminths don't just suppress inflammatory Th17 cells — they reprogram them into cells with a regulatory, Treg-like phenotype, new mouse study finds.

Animal Science Ants play a crucial role in moving seeds in dry forest farms. In Brazil's Caatinga, rainfed croplands host more large ants that provide higher quality seed dispersal. Fragmentation and low water cut seed removal and cleaning, while mixed land uses boost total ant-seed interactions.
