Is human reproduction exceptionally egalitarian compared to other mammals, or do we have high "reproductive skew"? It's a question that a team of more than 100 researchers tackled in a recent paper published in PNAS. Their finding? “Human exceptionalism has been greatly exaggerated,” says SFI External Professor Monique Borgerhoff Mulder (UC Davis).

James Pelkey, former member of the SFI Board of Trustees, passed away on February 16, 2023, at the age of 77 in Maui, Hawaii. A committed supporter of the research carried out at SFI, Pelkey served on SFI’s Board of Trustees for a decade, and became the Chair of the Board from 1990-1992.

For the past 14 years, SFI has played an important role at pivotal moments in Milena Tsvetkova's career, including her recent four-month sabbatical. 

SFI Science Board member and External Professor Lauren Ancel Meyers and colleagues organized a May 17-18 workshop to reimagine how pandemic simulation games can help us prepare for the superbugs of the future, bringing together epidemiologists; military war game specialists; officials from the Centers for Disease Control and Prevention; and experts in human behavior, cognitive science, and artificial intelligence. 

AI and the Barrier of Meaning 2, a workshop held at the Santa Fe Institute on April 24–26, brought together experts working in AI, cognitive science, philosophy, anthropology, linguistics, neuroscience, and law. Videos of the talks from the workshop are now available on YouTube. Similar to the first AI and the Barrier of Meaning workshop, held in 2018, the event focused on questions related to “understanding” and what it means to “extract meaning” in a humanlike way.

Information architectures — the rules and norms that govern the spread of information — likely serve a dominant force in shaping society. A May 9-11 workshop meets to explore a host of emerging questions around information architectures and their impact on our lives.

Human innovations often arise "ahead of their time," but evolution, we’re told, innovates only in response to environmental conditions. In his new book, Sleeping Beauties: The Mystery of Dormant Innovations in Nature and Culture, SFI External Professor Andreas Wagner urges us to consider another possibility. “What if,” he asks, “many innovations arise before their time,” in nature just as in human culture? 

In a new paper in PNAS, Eric Libby, Christopher Kempes, and Jordan Okie take a quantitative approach to begin tackling one of the great mysteries of biology: how eukaryotes arose. 

Understanding higher-order interactions — phenomena that involve three or more entities — can be tricky, says SFI Complexity Postdoctoral Fellow Yuanzhao Zhang. In a new paper in Nature Communications, Zhang and his colleagues show how the choice of network representation can influence the observed effects.

As Covid roared through prisons in 2020, the U.S. prison population fell by as much as 30 percent, creating the largest, fastest reduction in prison population in American history. But this decarceration disproportionately benefited white incarcerated people, sharply increasing the fraction of incarcerated Black and Latino people. A new study in Nature shows that this increased racial disparity in U.S. prisons stems in large part from a long-standing problem with the justice system: Non-white people tend to get longer sentences than white people for the same crimes.

In times of crisis, groups of people respond in a variety of ways — with sometimes vastly different outcomes. A company might be resilient during a recession while another business fails. Some groups refused to get vaccinated for COVID-19, remaining more vulnerable to the virus, while others quickly adopted the new vaccine. Why do some communities and organizations struggle to respond deftly to threats? A new paper in the Journal of the Royal Society Interface presents a new conceptual framework that could provide answers in the future.

AI research papers typically report only aggregate results, without the granular detail that will allow other researchers to spot important issues like errors in recognizing certain faces on racial and gender lines. In a new paper, SFI Professor Melanie Mitchell and co-authors explore this problem and suggest solutions. 

A new study co-authored by SFI Complexity Fellow Daniel Muratore takes a close look at the carbon-to-nitrogen ratios in marine microorganisms, with results that may lead researchers to rethink the role of these microorganisms in the oceanic carbon cycle.

A March 15-17 working group brought a complex-systems lens to study the paradox of why human societies have increased in intricacy despite the second law of thermodynamics's wisdom that entropy increases over time. 

SFI Sabbatical Visitor Carlos Gershenson, a research professor at the Universidad Nacional Autónoma de México, spends his sabbatical at SFI to finish work on his book Balance.

The specter of information is haunting the sciences. With these words, Wojciech H. Zurek invited fellow scientists to attend the 1989 Santa Fe Institute workshop on which the proceedings volume Complexity, Entropy & the Physics of Information was based. In a two-volume reprint, the SFI Press offers an affordable and accessible update to the original text, with a new preface from attendee Seth Lloyd that contextualizes the significance of this record of a meeting that marked the intersection of information, physics, complexity, and computation.

SFI's summer undergraduate research program celebrates three decades this year.

SFI External Professor Wendy Carlin (University College London) has received the inaugural RES Medal for Services to the Economics Profession from the Royal Economic Society. 

SFI External Professors Amos Golan, Matthew Jackson, and Doug Eriwn have been named fellows of the American Association for the Advancement of Science (AAAS) for 2022, the association announced on January 31, 2023.

In December 2022, SFI opened applications for its Postdoctoral Fellows to apply for funding through the Lou Schuyler Internal Postdoctoral Research Grant Fund. Now in its second round, the fund offers SFI Postdoctoral Fellows up to $15,000 per grant to explore new areas of research or expand the scope of their current projects.
