New tool untangles complex dynamics on hypergraphs

Networks are a powerful model for describing connected systems in biological, physical, social, and other environments. As useful as they are, though, conventional networks are static and are limited to describing links between pairs of objects. In a paper published in Communications Physics, SFI Schmidt Science Fellow Yuanzhao Zhang and collaorators describe a new framework for simplifying the analysis of synchronization patterns in a wide variety of systems that include hypergraphs, temporal networks, and multilayer networks.

When does reputation lie?

Is merit necessarily achieved, or does social status influence whether a person succeeds or is trapped in a system?  These are questions explored in a new paper published in Philosophical Transactions of the Royal Society B by former SFI postdocs Eleanor Power and Marion Dumas and their colleague Jessica Barker.

Virtual topical meeting takes stock of market risk and social media

In an age where it's easier to get on social media than off of it, we still know shockingly little about how the scope, speed, and structure of online communication forums impact beliefs about stock market investing. This October, SFI partners with UBS to host a virtual topical meeting titled “Technology and Risk: Will Speedier and Deliberate Communication Bring Higher Levels of Risk?”

A statistical fix for archaeology's dating problem

Archaeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there’s never been a statistical fix that works — until now.

New Complexity Explorer tutorial teaches Open Science

To solve our most intractable and pressing scientific problems, humanity needs the best possible science to innovate solutions. The best possible science is science that is open, reproducible, replicable, transparent, and inclusive, says Open Science advocate and SFI Complexity Postdoctoral Fellow Helena Miton.

Study: As cities grow in size, the poor 'get nothing at all'

On average, people in larger cities are better off economically. But a new study published in the Royal Society Interface builds on previous research that says, that’s not necessarily true for the individual city-dweller. It turns out, bigger cities also produce more income inequality.

SFI researchers publish new theory of life’s multiple origins

What if life evolved not just once, but multiple times independently? 

In a new paper, published in the Journal of Molecular Evolution, Santa Fe Institute researchers Chris Kempes and David Krakauer argue that in order to recognize life’s full range of forms, we must develop a new theoretical frame.

Virtual graduate workshop students explore vaccine hesitancy

The Graduate Workshop in Computational Social Science (GWCSS) has been a core feature of summers at SFI for a quarter-century. This year, in response to the ongoing pandemic, the 26th GWCSS was condensed into two intensive and productive days online, and students completed a homework problem centered around a question of contemporary significance.
