Terror networks are comparable in their structure to hierarchical organization in companies and certain online social networks, say the authors of a paper outlining how
a mathematical model to disrupt flow of information in a complex real-world network, like a terrorist organization, can work, using minimal resources. 

In those hierarchical social networks, information flows in one direction from a source, which produces the information or data, downwards to sinks, which consume it. 


A group contends that the journal impact factor (JIF), which ranks scholarly journals by the average number of citations their articles attract in a set period, has increasingly become an obsession in science. Impact factor of articles is used in evaluating research for funding, hiring, promotion, or institutional effectiveness. 


Hofstadter's Butterfly, a complex pattern of the energy states of electrons that resembles a butterfly, has appeared in physics textbooks as a theoretical concept of quantum mechanics for nearly 40 years but had never been directly observed - until now.

What was the diet and movements of the first New Zealanders like?

Isotopes from their bones and teeth can tell us. Researchers say they have been
able to identify what is likely to be the first group of people to colonize Marlborough's Wairau Bar, possibly from Polynesia around 700 years ago. They also present evidence suggesting that individuals from two other groups buried at the site had likely lived in different regions of New Zealand before being buried at Wairau Bar. 

The researchers undertook isotopic analyses of samples recovered from the koiwi tangata (human remains) of the Rangitane iwi tupuna (ancestors) prior to their reburial at Wairau Bar in 2009.
