Histamine can trigger itchiness, watery eyes, sneezing, trouble breathing, headaches, and asthma attacks, among other problems. Homes with bedbug infestations can become histamine Dutch ovens, according to a new study led by entomologists and health experts at North Carolina State University. The researchers found that histamine levels

Deadly battles play out several times a day in the Ivory Coast’s Comoé National Park, leaving wounded behind. The fights break out when hundreds of African Matabele ants march off to raid a nearby termite mound to slaughter termite workers and haul them back to the nest to feed the colony. But termites, with their strong, sharp mandibles, aren’t easy prey, and raiders often get limbs bitten off in the fight.

In the aftermath of a raid, researchers are finding evidence that the ants care for their wounded. The wounded ants secrete a pheromone that calls other returning raiders to carry their injured comrades home. Back at the nest, healthy nest-mates clean the injured ants’
