SFI archeologists Stefani Crabtree and Devin White win a prestigious HPC Innovation Excellence Award for their work developing supercomputing methods to study human migration.

SFI Science Board Member Simon Levin (Princeton University) was recognized by the BBVA Foundation for his essential mathematical contributions to the field of spatial ecology. 

A recent study led by SFI External Professor Marten Scheffer identified a set of striking patterns in the written record that suggest that, in the universe of language, an era framed by sentiment and individuality has been on the rise for decades. A response from External Professor Simon DeDeo gives a replication of the findings with similar results and also offers remarks on both the methodological challenges and some of the interpretive questions the work raises.

Hate speech and disinformation have become intractable problems on social media and other online platforms— might counter speech be an effective strategy to curb it? It’s a difficult thing to address scientifically because so many societal factors are at play beyond the online forums. However, a study published in EPJ Data Science uses a multifaceted approach to begin exploring the question.

Over the past three years, SFI’s Applied Complexity Network (ACtioN) has had a front-row seat in a series of meetings where SFI researchers have been evolving a new kind of engineering, one better suited to the complex systems that drive the contemporary world. Called emergent engineering, it generates the conceptual frameworks and design principles that practitioners need to carry out engineering projects that engage with adaptive agents.

The laws of physics underlying everyday life are, at one level of description, completely known, and can be summarized in a single elegant — if quite complex — equation. That’s the claim Santa Fe Institute physicist Sean Carroll makes in a recent paper.

The intensifying search for life on other worlds begs an important question: Will we recognize life when we find it? New work co-authored by SFI External Professor Sara Imari Walker offers an innovative approach.

The advancement of everything from science to education relies in large part on the ability to come up with new ideas. But under what conditions is innovation most likely? To help answer this key question in the science realm, SFI External Professor Manfred Laubichler and colleagues developed a framework to identify the origins of innovation across one field: evolutionary medicine.

We can’t understand polarization unless we analyze it as a complex system, argues SFI External Professor Scott Page (University of Michigan) in a commentary for a special feature on the dynamics of political polarization in the Proceedings of the National Academy of Sciences.

Polarization is dangerous for democracy. Though the U.S. Constitution was designed to harness rivalry with a diverse, redundant, and modular set of institutions, if that rivalry curdles into the belief that your competitors are your enemies, those institutions may not be strong enough to hold a nation together. In a Perspective piece in the Proceedings of the National Academy of Sciences, SFI External Professor Jenna Bednar (University of Michigan) argues that polarization poses three perils in particular.

A new study in the Proceedings of the National Academy of Sciences suggests extreme polarization can be avoided when two sides of a stubbornly intolerant population have low exposure to each other. This paper is part of a PNAS special issue on the dynamics of polarization.

SFI and EU partners launch International Summer School focused on social disintegration. Applications open through January 18, 2022.

Yuanzhao Zhang, a Schmidt Science Fellow at SFI, was one of three recipients of the Complex Systems Society’s 2021 Emerging Researcher Award.

In a new article in The Proceedings of the Royal Society B, SFI External Professor Mary I. O’Connor and colleagues argue that public policy would benefit greatly if it were informed by the science of biological feedback.

In the largest single donation in its history, the nonprofit Santa Fe Institute will receive $50 million from legendary investor Bill Miller. The gift will advance the Institute's pioneering science of complex systems by growing its research community and expanding the facilities in which it works. 

For the past few years, SFI Professor David Wolpert and physicist Artemy Kolchinsky, a former SFI postdoctoral fellow, have been collaborating to better understand the connection between thermodynamics and information processing in computation. Their latest exploration of the topic, published in Physical Review E, looks at applying these ideas to a wide range of classical and quantum areas, including quantum thermodynamics.

A new book from the SFI Press, edited by David Krakauer Geoffrey West, underscores the importance of resisting simple answers in combatting such a complex phenomenon as a global pandemic and instead recognizing its inherently messy nature.

In a study published in the Proceedings of the National Academy of Sciences, SFI External Professor Amy Bogaard and colleagues document the distribution of valuable artifacts across Southeast Asian gravesites over an era that spans from the Neolithic Period to the Agricultural Revolution.

In a new paper published in Physical Review X, SFI physicists David Wolpert and Artemy Kolchinsky explore more realistic bounds on entropy production by considering how constraints affect Landauer’s limit. Their approach to understanding how much work can be extracted from a physical system could lead to a better understanding of the thermodynamic efficiency of various real-world systems, ranging from biomolecular machines to recently-developed “information engines” that use information as fuel.

Mathematicians who study dynamical systems often focus on the rules of attraction, finding the “basins” that show the states the systems are drawn to. For straightforward systems, the shape and size of a basin is comprehensible, but not so for more complicated systems. In fact, they may look like the tentacles of an octopus, according to a new paper by SFI Postdoc Yuanzhao Zhang and co-author Steven Strogatz.
