That’s because in mink and other carnivorous (meat-eating) animals, three key genes required to detect and respond to infection by pathogens have lost their function. If these genes were working, they would activate inflammatory responses to fight off these disease-causing organisms.… read on > read on >
The health impact of wildfires is already huge, and new research suggests it might also raise a mom-to-be’s risk for preterm birth, according to a new study.
