Evolution shapes new rules for ant behavior
In ancient Greece, the city-states that waited until their own harvest was in before attacking and destroying a rival community's crops often experienced better long-term success.
Researchers glue bar codes on to ants to study individual behavior within group (w/ video)
Fire ants assemble as a 'super-organism' (w/ video)
The ants may go marching one by one, but they end up forming a superstructure of thousands -- and together they can form a raft that stretches the boundaries of the laws of physics, according to new research ...
Next generation of algorithms inspired by problem-solving ants
(PhysOrg.com) -- An ant colony is the last place you'd expect to find a maths whiz, but University of Sydney researchers have shown that the humble ant is capable of solving difficult mathematical problems.
Ants die alone, protecting their nest mates from infection
Orphan army ants join nearby colonies
(PhysOrg.com) -- Colonies of army ants, whose long columns and marauding habits are the stuff of natural-history legend, are usually antagonistic to each other, attacking soldiers from rival colonies in border ...
Field study suggests brain size in ants adheres to specialization hypothesis
Meet the "swarmies"- robotics' answer to bugs
(Phys.org) —A small band of NASA engineers and interns is about to begin testing a group of robots and related software that will show whether it's possible for autonomous machines to scurry about an alien ...
Zombie ant fungi manipulate hosts to die on the 'doorstep' of the colony
A parasitic fungus that must kill its ant hosts outside their nest to reproduce and transmit their infection, manipulates its victims to die in the vicinity of the colony, ensuring a constant supply of potential ...
Dopamine turns worker ants into warrior queens
(Phys.org) —The ritualized fighting behavior of one ant species is linked to increases in dopamine levels that trigger dramatic physical changes in the ants without affecting their DNA, according to research ...
Scientists discover that ants, like humans, can change their priorities
All animals have to make decisions every day. Where will they live and what will they eat? How will they protect themselves? They often have to make these decisions as a group, too, turning what may seem ...
Mutual benefits: Stressed-out trees boost sugary rewards to ant defenders
When water is scarce, Ecuador laurel trees ramp up their investment in a syrupy treat that sends resident ant defenders into overdrive, protecting the trees from defoliation by leaf-munching pests.
Ants turn unwelcome lodgers into a useful standing army
Mercenary soldiers are notoriously unreliable because their loyalty is as thin as the banknotes they get paid, and they may turn against their employers before moving on to the next dirty job. Not so in fungus-farming ants, ...
A mathematical framework for understanding cities: Part social reactor, part network
Cities have long been likened to organisms, ant colonies, and river networks. But these and other analogies fail to capture the essence of how cities really function.
