Ants may not be able to adjust their behavior in response to rising temperatures. That's a problem because if ants get too hot, they die.

The ways eastern fence lizards have changed in response to red imported fire ants demonstrate how species can adapt to survive the presence of invasive predators.

Ant pupae secrete a never-before observed milk-like fluid that adults and larvae drink to keep the entire colony healthy.

Chowing down on fire ants might bolster lizard immune systems for attacks in the future, "somewhat like a vaccine," researchers say.

Ants go through both physiological and behavioral changes to adjust to unnatural settings like urban sprawl, a new study shows.

Ant feet are equipped with an array of tools – from retractable sticky pads to claws to special spines and hairs – enabling them to defy gravity and grip virtually any surface.

Queen ants live a lot longer than workers. A new study indicates that protein that suppresses insulin plays a role in their longevity.

When ants get together, they make collective decisions a bit like networks of neurons in a brain, according to new research.
