Van Savage and Geoffrey West: Why do we sleep? (Aeon)

Much of modern sleep research has focused on the hormones, cells, and enzymes that regulate how we sleep, and what goes wrong when we can't sleep. But “all of this leaves unanswered the more fundamental question of why we need to sleep in the first place. What, in fact, is sleep’s function?” ask SFI's Van Savage and Geoffrey West in an essay for Aeon magazine.

A statistical fix for archaeology's dating problem

Archaeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there’s never been a statistical fix that works — until now.

Study: As cities grow in size, the poor 'get nothing at all'

On average, people in larger cities are better off economically. But a new study published in the Royal Society Interface builds on previous research that says, that’s not necessarily true for the individual city-dweller. It turns out, bigger cities also produce more income inequality.

SFI researchers publish new theory of life’s multiple origins

What if life evolved not just once, but multiple times independently? 

In a new paper, published in the Journal of Molecular Evolution, Santa Fe Institute researchers Chris Kempes and David Krakauer argue that in order to recognize life’s full range of forms, we must develop a new theoretical frame.

Virtual graduate workshop students explore vaccine hesitancy

The Graduate Workshop in Computational Social Science (GWCSS) has been a core feature of summers at SFI for a quarter-century. This year, in response to the ongoing pandemic, the 26th GWCSS was condensed into two intensive and productive days online, and students completed a homework problem centered around a question of contemporary significance.

Research brief: Really real patterns

Does the universe follow patterns, or do we humans just see them wherever we look? In a new paper for the Australasian Journal of Philosophy, SFI Program Postdoctoral Fellow Tyler Millhouse proposes a criterion evaluating just how real a pattern is likely to be.

How chemical reactions compute

If chemical reactions can be “programmed” like other types of computing machines, they might be exploited for applications in many areas, including intelligent drug delivery, neural networks, or even artificial cells, write SFI External Professor Juan Pérez-Mercader and Marta Dueñas-Díez in a review article for Frontiers in Chemistry.
