In the Middle Ages, did contracting leprosy necessarily increase a person's chances of dying? Yes, says a new paper. But it's complicated.
In a two-part lecture series in Santa Fe on September 25-26, economist John Geanakoplos explored why it is that out of all economic variables, debt causes the most trouble. Watch part one of his talk here and part two here.
Inequality, climate change, financial crises: New economics textbook puts complex concerns at its CORE
The Economy, a new SFI-inspired textbook, is published in paperback format and as a free, online interactive text. The book aims to address the gap between complex, real-world economic problems and the topics traditionally taught in first-year economics courses.
Cells compete for nutrients. Political campaigns compete for voters. According to new research published in Nature Scientific Reports, general principles may begin to explain how differing strategies play out where groups compete for resources.
SFI's free online course, Introduction to Dynamical Systems and Chaos with College of the Atlantic professor David Feldman, begins September 4. Topics to be covered include: phase space, bifurcations, chaos, the butterfly effect, strange attractors, and pattern formation.
A team led by SFI postdoctoral researcher Laurent Hébert-Dufresne asks under what conditions a Zika outbreak might be sustained where mosquitos play no role.
Groups of interconnected nodes, called “communities” or “modules,” represent real-world relationships like friend groups on Facebook, businesses in a supply chain. A new paper addresses the challenge of identifying whether, and ultimately where, these structures exist within a mass of data.
In a fresh look at 20th-century philosopher-economist Friedrich Hayek, three authors note how the Nobel laureate’s work exemplifies complexity economics. They also show how his political support of laissez faire economic policies needn’t necessarily follow.
In a recent paper published in Global Ecology and Biogeography, SFI External Professor John Harte, SFI Omidyar Fellow Andy Rominger, and Erica Newman, a postdoctoral fellow at the University of Arizona, suggest that a theory independent of mechanistic drivers, such as sunlight, can accurately describe the distribution of species in a forest.
The Santa Fe Institute is launching an InterPlanetary Project — the first project of its kind to combine celebration with experimentation, and conversation with analysis.
The Santa Fe Institute will be pursuing questions about general, universal principles of complex time with support from the James S. McDonnell Foundation (JSMF) through a five year, $2.5 million grant.
Recent advances in technology have allowed scientists to probe the molecular nature of life, analyzing thousands of genes at a time and recognizing patterns of gene interaction. In a recent paper published in Proceedings of the Royal Society B, complexity scientist Samuel Scarpino and co-authors explore gene co-expression networks that have evolved to help plants withstand drought and cold.
Bali's famous rice terraces, when seen from above, look like colorful mosaics because some farmers plant synchronously, while others plant at different times. The resulting fractal patterns are rare for man-made systems and lead to optimal harvests without global planning.
How we make decisions— or, rather, how neurons make decisions for us, is the subject of new research published in Frontiers in Neuroscience. In the study, Bryan Daniels, Jessica Flack, and David Krakauer uncover a two-phase collective decision-making pattern which may suggest a general principle of collective computation.
