ant : any of a family (formicidae) of colonial hymenopterous insects with a complex social organization and various castes performing special duties — Webster
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago, and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.
Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist mostly of sterile, wingless females forming castes of “workers”, “soldiers”, or other specialised groups. Nearly all ant colonies also have some fertile males called “drones” and one or more fertile females called “queens”. The colonies are described as superorganisms because the ants appear to operate as a unified entity, collectively working together to support the colony.
Ants have colonised almost every landmass on Earth. The only places lacking indigenous ants are Antarctica and a few remote or inhospitable islands. Ants thrive in most ecosystems and may form 15–25% of the terrestrial animal biomass. Their success in so many environments has been attributed to their social organisation and their ability to modify habitats, tap resources, and defend themselves. Their long co-evolution with other species has led to mimetic, commensal, parasitic, and mutualistic relationships. — Wikipedia
Myrmecology is a branch of entomology focusing on the scientific study of ants. Some early myrmecologists considered ant society as the ideal form of society and sought to find solutions to human problems by studying them. Ants continue to be a model of choice for the study of questions on the evolution of social systems because of their complex and varied forms of eusociality (social organization). Their diversity and prominence in ecosystems also has made them important components in the study of biodiversity and conservation. Recently, ant colonies are also studied and modeled for their relevance in machine learning, complex interactive networks, stochasticity of encounter and interaction networks, parallel computing, and other computing fields. — Wikipedia
Ant keeping is a hobby involving the capture, care, and observation of ants and ant colonies. — Wikipedia

In one species of ants, workers duel to establish new leadership after the death of their queen. While these sparring matches stretch for more than a month, changes in behavior and gene expression in the first three days of dueling can accurately predict who will triumph, according to a New York University study published in the journal Genes & Development.

What is it like to be a bee? Or a spider? Does a crab feel pleasure or pain? Behavioural and welfare science have moved on considerably in the past 20 years, but there is still a huge amount we don't know about how animals actually feel—or, indeed, whether they all do.

MedUni Vienna researchers led by Christian Gruber from the Institute of Pharmacology, with international collaborators, have shown that it is possible to dimerize the human neuropeptides oxytocin and vasopressin without forfeiting much of their efficacy. The researchers were inspired by a naturally occurring locust neuropeptide in the form of a dimer of two vasopressin-like molecules. "By making structural changes to the composition and orientation of the dimers, we managed to modify their […]

Imagine the texture of a plant. Many may come to mind—the smooth rubberiness of many tropical houseplants, the impossibly soft lamb's ear, the sharp spines of cacti, or the roughness of tree bark. But stickiness, in the flypaper-stick-to-your-fingers sense, probably isn't at the top of your list.
