Modular -- or cliquey -- group structure isolates the flow of communication between individuals, which might seem counterproductive to survival. But for some animal groups, more information isn't necessarily better, according to new SFI research published in Philosophical Transactions of the Royal Society B.
Understanding economies in times of crises? Modern macroeconomics failed so far. Researchers from the Complexity Science Hub Vienna are now proposing a novel method that makes the effects of shocks on out-of-equilibrium economies computable for the first time.
Physicists at the Santa Fe Institute and MIT have shown that Markov processes, widely used to model complex systems, must unfold over a larger space than previously assumed.
We are more original than we think -- this is what is being suggested by literary text analysis carried out by a new method of stylometry proposed by scientists from the Institute of Nuclear Physics Polish Academy of Sciences. The author's individuality can already be seen in connections between no more than a dozen of words in English text. It turns out that in Slavic languages authorship identification requires even fewer words and is more certain.
There's been a rapid resurgence of interest in understanding the energy cost of computing. Recent advances in this 'thermodynamics of computation' are summarized in a new review published in the Journal of Physics A.
Researchers at the Max Planck Institute and the Santa Fe Institute have developed a new model to explain the evolutionary origins of empathy and other related phenomena, such as emotional contagion and contagious yawning. The model suggests that the origin of a broad range of empathetic responses lies in cognitive simulation.
Using a statistical approach known as stylometry, which analyzes everything from the poem's meter to the number of times different combinations of letters show up in the text, a team of researchers found new evidence that Beowulf is the work of a single author.
Big data analysis of popular online dating website reveals that geographic distance within the US is the strongest driver of mutual romantic interest. At the city level, users in New York, Boston, Chicago, and Seattle may experience very different sub-markets depending on their age, sex, and race.
Women constitute approximately 47 percent of the workforce yet are underrepresented at the highest levels of business, government, medical and academic hierarchies. A team of researchers has developed a model, described in the journal Chaos, to study the ascension of women through professional hierarchies. It factors in the relative roles of bias and homophily and predicts that gender parity is not inevitable and deliberate intervention may be required in various fields to achieve gender balance.
Biophysicists have used an automated method to model a living system -- the dynamics of a worm perceiving and escaping pain. The model makes accurate predictions about the dynamics of the worm behavior, and these predictions are biologically interpretable and have been experimentally verified.
