The reshuffling of neurons during fruit fly metamorphosis suggests that larval memories don’t persist in adults.

A new genetics study of ant “social parasites” shows how complex sets of features can emerge rapidly and potentially split species.

Queen ants live far longer than genetically identical workers. Researchers are learning what their longevity secrets could mean for aging in other species.

Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex.

Field research suggests a new explanation for the synchronized flashing in fireflies and confirms that a novel form of “chimeric” synchrony occurs naturally.

The evolution of a defensive gland in beetles shows how organs can arise from novel cells carving out new functional niches for their neighbors.

From crumpled paper to termite mounds to three-sided coins, L. Mahadevan has turned the whole world into his laboratory.

Carpenter ants need endosymbiotic bacteria to guide the early development of their embryos. New work has reconstructed how this deep partnership evolved.

As Scarlett Howard taught honeybees to do arithmetic, they showed her how fundamental numbers might be to all brains.
