Med Research, EarlyView.This multi‐omics study identified genetic loci, gut microbiota, blood metabolites, and gray matter volumes of orbitofrontal cortex and cerebellum that were potentially relevant to alerting in healthy Chinese adults. Subsequent two‐step one‐sample Mendelian randomization further revealed a serial mediation pathway: Bacteroides intestinalis influences ...

Trends in Ecology & Evolution, 2002 In a recent paper, M. Beekman and co-workers carried out experimental and theoretical investigations into the behaviour of a biological system consisting of a colony of Pharaoh's ants. By manipulating the colony, the foraging behaviour of the ants was, remarkably, shown to be capable of undergoing a transition between a disordered and an ordered state ...

Sensitive ants are sensible ants
Proceedings of the 14th annual conference on Genetic and evolutionary computation, 2012This paper introduces an approach to evolving computer programs using an Attribute Grammar (AG) extension of Grammatical Evolution (GE) to eliminate ineffective pieces of code with the help of context-sensitive information.The standard Context-Free Grammars (CFGs) used in GE, Genetic Programming (GP) (which uses a special type of CFG with just a single

Ant opsins: Sequences from the Saharan silver ant and the carpenter ant
Invertebrate Neuroscience, 1996cDNA clones encoding opsins from compound eyes of carpenter ant, Camponotus abdominalis, and Saharan silver ant, Cataglyphis bombycina, were isolated from cDNA libraries. The opsin cDNAs from each species code for deduced proteins with 378 amino acids which are 92% identical.

Perhaps the most sophisticated tools for dissecting the social structure of ants are those ants that exploit other ants. These exploiters range from ants that merely rob others to those that use common trail systems, while yet more devious forms share both the nests and the food supply of their hosts.

The Numbers of Ants in Ant Colonies
Annals of the Entomological Society of America, 1942The number of ants in an ant hill is a question of perennial interest. Forel's estimate of a maximum of half a million to a hill was not supported by Yung's actual enumerations (1900) which showed that of five hills of Formica rufa only one approximated one hundred thousand ants, the other four being well below that number.

Ants belong to the order Hymenoptera, along with bees, wasps, yellow jackets, etc., they are the most successful animal genera in this world. It is their selfless social structure which accounts for their huge impact. Their effect on man ranges from the parasol ant, which makes plant cultivation untenable in certain parts of South America, to ...

The design of artificial systems inspired by biological behavior is recently attracting considerable interest. Many biological agents such as plants or animals were forced to develop sophisticated mechanisms in order to tackle various problems they encounter in their habitat.

The Sociological Review, 1998
The paper explores one after the other the four difficulties of actor-network theory, that is the words ‘actor’, ‘network’ and ‘theory’—without forgetting the hyphen. It tries to refocus the originality of what is more a method to deploy the actor's own world building activities than an alternative social theory.
