SFI welcomes new Program Postdoctoral Fellow Arseny Moskvichev, who is fascinated by how people use language and abstraction to communicate and share knowledge.
SFI welcomes Complexity Postdoctoral Fellow Kelle Dhein, who hopes to shed new light on the debate about what information is by exploring how particular concepts of information influence present-day research in the behavioral sciences.
The climate and biodiversity crises are stressing wildlife species around the world in unprecedented ways. A species’ evolutionary past, however, can help shed light on its fate in the face of future environmental change. Helping to fill in these crucial data gaps is the focus of Complexity Postdoctoral Fellow Jack Shaw’s work at SFI.
In a new paper, SFI Complexity Fellow Stefani Crabtree and Jennifer Dunne, SFI’s Vice President for Science, lay out the first comprehensive definition of archaeoecology, an emerging field that can fill a knowledge gap about important questions of how humans and nature interacted and shaped each other across different places and through time.
Many researchers at SFI are driven by a curiosity to understand the laws that underlie various forms of life. Work spearheaded more than two decades ago by SFI’s Geoffrey West, Brian Enquist, and Jim Brown has illustrated that organisms’ biological functions are governed by scaling laws. Other researchers have gone on to discover that human social life, from cities to organizations, follows similar rules. “These laws apply, with their own specificities, across domains,” says Veronica Cappelli, an SFI Applied Complexity Postdoctoral Fellow.
A new kind of predictive network model could help determine which people will change their minds about contentious scientific issues when presented with evidence-based information. A new study in Science Advances presents a framework to accurately predict whether a person will change their opinion about a certain topic. The approach estimates the amount of dissonance, or mental discomfort, a person has from holding conflicting beliefs about a topic.
Imagine a bookshelf that stretches far into the distance, laden with genre fiction: potboilers, romances, thrillers. Farther down, we glimpse the royal blue of a Fitzcarraldo edition. The catch? Every book has the same author: E. Machina. They’ve all been written by AI. To SFI External Professor Dan Rockmore (Dartmouth College), we’re closer than we think to the world of that bookstore. The working group “The Anxiety of the Computational” explores questions about how AI-written literature might impact the humanities.
Ten percent of carbon burned on Earth comes from devices like your cellphone, quietly computing even when you aren’t looking at it. Developing a greater understanding of the thermodynamics of computation like that done by your cellphone is critical to reducing energy use. It is also critical to understanding a host of deep, long-standing scientific problems. An Aug. 15–17 workshop, "The Thermodynamics of Natural and Artificial Distributed Computational Systems," meets to identify challenges, opportunities, and priorities to push forward scientific investigations of this topic.
Heatwaves are triggering wildfires and killing people around the globe. The climate emergency and the planet’s sixth mass extinction event have already begun. A special themed issue in Philosophical Transactions of the Royal Society B: Biological Sciences addresses what actions have led us to this point and what we can do from here.
At present, the global economy is experiencing structural changes that often seem unprecedented. Rapid technological evolution, climate migration, demographic shifts, and deepening inequality all contribute to the current flux of economic systems. The threat of economic reconfiguration also appears to be fueling political polarization around the globe. In light of the current patterns that researchers are observing, many seek new methods to understand the mechanisms that shape the new landscape. An August 8-12 working group explores “How Can Complexity Economics Give More Insight into Political Economy?”
Imagine that we rewound life’s tape to a distant past and let evolution play out again. Which species and traits would succeed the second time? Which characteristics would emerge over and over again, invariant to random chance? Aviv Bergman of the Albert Einstein Institute of Medicine is spending his sabbatical at the Santa Fe Institute, developing computational models designed to answer those questions.
SFI welcomes nine new members to our External Faculty and one rejoining member.
SFI Research Development Director Susan Carter has received a 2022 Mentoring Award from the National Organization of Research Development Professionals (NORDP).
To address climate change and other societal challenges like rising inequality, human migration, and biodiversity loss, humanity must consider the ecological, economic, and political constraints of our planetary systems. In late July, the International Centre for Theoretical Physics (ICTP) in Trieste, Italy, hosted a workshop to discuss these considerations and foster collaboration across research communities. SFI co-hosted the workshop in partnership with ICTP and the Fondazione Internazionale Trieste.
A general theory describing how life depends on temperature has been lacking — until now. In a recent paper in the Proceedings of the National Academy of Sciences, research led by José Ignacio Arroyo, an SFI Postdoctoral Fellow, introduces a simple framework that rigorously predicts how temperature affects living things, at all scales.
After two years of online-only and postponed events, SFI's summer education programs are back in person. June brought students from around the world to participate in the Undergraduate Complexity Research, Complex Systems Summer School, Graduate Workshop in Computational Social Science, and Advanced Graduate Workshop programs.
By taking another look at the complex relationship between crime and society, researchers at the University of Chicago, including SFI External Professor James Evans, have developed an algorithm that can predict urban crime one week in advance with 90% accuracy. The study, published in Nature Human Behavior, analyzed eight cities — Chicago, Atlanta, Austin, Detroit, Los Angeles, Philadelphia, Portland, and San Francisco — and found consistent results.
In human cultural life, change often happens in a few notable ways. Some human institutions, like fashion and political opinions, seem to be in constant flux. Others, such as beliefs and scientific theories, change so slowly as to appear static, before suddenly and dramatically shifting course. A new paper in PLOS ONE by SFI’s David Krakauer and Jessica Flack with co-author Phillip Poon offers an underlying framework to describe these changes, both fast and slow.
One of the great goals in physics is to discover whether gravity and the three other fundamental forces in the Universe — strong, electromagnetic, and weak — can be united into a single force, and many superstring and grand unified theories have been created that assume this is possible. But no such grand unified theory has ever been proposed that would unite the characteristics of life — until now.
From its inception in 2017, the Santa Fe Institute’s Research Coordination Network has been bringing interdisciplinary researchers together to study life’s possible origins. This summer, SFI hosts two working groups through the RCN: “Feasible but Undiscovered Metabolisms,” from July 11–16, and “Multiple Life,” from August 22–26.
