03 Jul 2023 --- US-based researchers have successfully treated honey bees with a novel immune system booster for deadly viruses causing losses of the critical pollinator on a global level. Honey bees play a crucial role in our food system and production by pollinating crops, and their population decline, partly caused by viruses, is a direct danger to human health. The scientists found that bees could fight many viruses when encouraging their cells to produce free radicals.
