El artículo presenta un análisis de la vida y anatomía de las hormigas, con énfasis en su organización social. El autor ofrece una descripción de distintos comportamientos de las hormigas, a la par que compara algunas de estas características con el comportamiento humano. Otros aspectos discutidos son estructura de los hormigueros, simbología y mitos en torno a las hormigas.

The article focuses on a study which found that the impressive spines in Pheidole ants which may deter predators, are not used for defence or attack but to chomp into thick seeds, and that the worker ants are very shy and are often the first to run away and hide.

The article discusses research by Johan Billen of the Catholic University of Leuven (KUL) which found that south-east Asian Camponotus cylindricus ants, which are able to secrete a deadly substance when their colony is threatened by exploding, have large gland reservoirs which rupture very easily.

Reports on German zoologists' analysis of mandibles of Odontomachus ants. Speed with which the jaws clutch victims; Sharp tooth in each end of the mandibles as doing the damage; O. bauri ants as using their mandibles for slower preys and as a defense against termites; Other uses of the jaws.

Two quizes related to the size of the Eurhopalothrix zipacna ant species, discovered by scientist Jack Longino, are presented.

This article discusses the discovery of a new ant species in the rainforests of Brazil. The ant is described as having a pale body, no eyes and mouth parts like forceps. Ant biologist Corrie Moreau suggests the ant could be a subterranean ant. She adds that the discovery of a single ant can offer us so much about the evolution of ants. The report will be online in the September 15, 2008 issue of "Proceedings of the National Academy of Sciences."

The article reports on the discovery of a new species of ant in South America called Martialis heureka. The ant has no eyes, with pale body and has long fanglike mouthparts. Christian Rabeling found the new species in the rainforest and decided to analyze its genetic material or DNA. Rabeling claims that his DNA analysis indicates that the species is only distantly related to other ant species.

This article reports on the mouth and jaws of soldier ants from the species Atta laevigata and how they are used for defense, as well as leaf-cutting and farming behavior. Ants developed farming behavior 50 million years ago and leaf-cutter ants appeared 8 to 12 million years ago. The article also discusses researchers Ted Schultz and Seán Brady, their work with the Smithsonian Institution in Washington, D.C. and their publication in the "Proceedings of the National Academy of Sciences."

Focuses on the head anatomy of the Atta cephalotes, a tropical ants subject to decapitation by parasitic flies of the genus Neodohrniphora. Measurement of the head; Performance of the ants after mating; Development of the egg into larva.
