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. 

There's a complex paradox at play in the dynamics between mask-wearing and the spread of disease: While masking reduces transmission rates and consequently disease prevalence, the reduction of disease inhibits mask-wearing — thereby promoting epidemic revival. A new study led by researchers at the University of Virginia and co-authored by SFI's Simon Levin and Stefani Crabtree explores these complex dynamics. 

In a June 14-16 SFI workshop, “The Structure of Technology,” researchers seek to develop better frameworks to capture how technology emerges, takes shape, and shapes the world in turn. The workshop is the first of a series of meetings that are taking place through SFI’s Emergent Political Economies grant and research theme. 

The immune system is almost fantastically complex, and many basic questions remain unanswered about how it manages to keep us safe from intruders without attacking our own tissues. A June 8-10 SFI working group, Distributed Computing Perspectives on Theoretical Immunology, gathered a diverse community of researchers to both revisit classic problems in immunology with a fresh face and ask what new questions have arisen, taking advantage of recent developments in both biology and computer science.

The world is rife with rankings and orderings, but these hierarchies are only observed after the fact. That makes it difficult to know the true rankings of a system. In a recent paper published in Physical Review E, SFI's George Cantwell and Cris Moore offer a new model to evaluate rankings. 

SFI's two-day working group “Language as a window into mind and society” will discuss the many powerful roles language plays in the human mind and in our societies, and how our implicit biases flow into the language-based technologies we build.

On April 30, 2022, the Santa Fe Institute’s Science Board hosted its annual symposium. The meeting’s topic — political economy and climate change — is central to SFI’s new Emergent Political Economies research theme, and will remain a focus of SFI research for the duration of the five-year grant and beyond. 

A May 17-20 working group aims to expand the boundaries of our understanding of music by pooling the expertise of researchers from disparate disciplines.

SFI External Professor Mark Newman (University of Michigan) has been named a Fellow of the Royal Society, the Society announced on May 10, 2022

SFI External Professor and Science Board member Ricardo Hausmann (Harvard University) was named co-chair of SFI’s Science Board at the board's 2022 spring meeting.

SFI External Professor Wendy Carlin has been named an international honorary member of the American Academy of Arts and Sciences (AAA&S) the Academy announced on April 28, 2022.
