To find the right network model, compare all possible histories

Scientists rarely have the historical data they need to see exactly how nodes in a network became connected. But a new paper by SFI's George Cantwell offers hope for reconstructing the missing information, using a new method to evaluate the rules that generate network models.

Accounting for the gaps in ancient food webs

Studying ancient food webs can help scientists reconstruct communities of species, many long extinct, and even use those insights to figure out how modern-day communities might change in the future. There’s just one problem: only some species left enough of a trace for scientists to find eons later, leaving large gaps in the fossil record — and researchers’ ability to piece together the food webs from the past.

A new paper by paleoecologist Jack Shaw, SFI's Jennifer Dunne, and other researchers shines a light on those gaps and points the way to how to account for them.

New paper: What makes an explanation good enough?

What makes an explanation good enough? As a personal matter, people have different answers to this question, and not all of them agree, says a new paper in Trends in Cognitive Sciences by Simon DeDeo and Zachary Wojtowicz. The authors use Bayes’ Rule, a famous theorem in probability and statistics, to investigate what we value in scientific and moral explanations.

Jennifer Dunne reflects on a year without ‘superpowers’

The Santa Fe Institute has always been defined by its ability to bring diverse, leading thinkers into the same room to tackle important research questions. So for SFI, 2020 has been something like stepping into that red chamber in the Fortress of Solitude. Jennifer Dunne, SFI’s Vice President for Science, jokes that the pandemic, with its necessary restrictions on in-person gatherings, “took away our superpower.” In this Q&A, Dunne talks about which aspects of SFI science can and cannot be replicated in a virtual environment, and what this means going into 2021.
