New approach can control large complex networks, from cells to power grids As the world becomes increasingly connected, the need to ensure the proper functioning of its many underlying networks -- such as the Internet, power grids, global air transportation and ecological networks -- also is increasing. But controlling networks is very difficult. Now a Northwestern University research team has developed the first broadly applicable computational approach identifying interventions that...

Mathematicians at the University of York in the UK and the University of Canterbury in New Zealand say they have disproved a widely accepted theory underpinning the operation of complex networks of interactions in the natural world. Networks are a powerful way to describe ecological communities, which typically involve large numbers of species that can exhibit both negative (e.g. competition or predation) and positive (e.g. mutualism) interactions with one another. Recent mathematical and...

Ever wonder why your friends have more friends than you or diamond is harder than graphite? A new article by a Northwestern University complex networks expert discusses how networks governing processes in nature and society are becoming increasingly amenable to modeling, forecast and control. The article establishes relationships between seemingly disparate topics such as the friendship paradox -- by which our friends have on average more friends than we do -- and why carbon can result...

Much as meteorologists predict the path and intensity of hurricanes, Indiana University's Alessandro Vespignani believes we will one day predict with unprecedented foresight, specificity and scale such things as the economic and social effects of billions of new Internet users in China and India, or the exact location and number of airline flights to cancel around the world in order to halt the spread of a pandemic.In tomorrow's (July 24) "Perspectives" section of the journal Science,...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
