Analysis of nearly 2,000 people living in remote villages in Honduras reveals who’s spreading gut microorganisms to whom. Originally published on November 20, 2024

So, we’ve found ourselves living through the worst pandemic in over a century, surrounded by uncertainty and drastic change. What comes next? Originally published on February 11, 2021.

It is almost exactly one year since the coronavirus Sars-CoV-2 was identified by Chinese scientists as the source of a new, lethal respiratory illness. Originally published on December 21, 2020.
 

When people work together on a project, they often come to think they’ve figured out the problems in their own respective spheres. If trouble persists, it’s somebody else—engineering, say, or the marketing department—who is screwing up. That “local focus” means finding the best way forward for the overall project is often a struggle. But what if adding artificial intelligence to the conversation, in the form of a computer program called a bot, could actually make people in groups more productive?

Our automated future has already arrived — at least, to some extent. Algorithms and smart devices help people choose what to buy, what to read, what to watch, and which roads to take. But social scientists Nicholas Christakis and Hirokazu Shirado at Yale University wanted to understand what this means on a bigger scale: how do machines change how humans interact with each other? And can robotic colleagues help humans work together more effectively? Originally published on May 17, 2017.

Unpredictable artificial intelligence (AI) doesn’t sound like a good thing. But a new study shows that computers that behave randomly can push us to better coordinate our actions with others and accomplish tasks more quickly. The approach could ease traffic flow, improve corporate strategy, and possibly even tighten marriages. Originally published on May 17, 2017.

Physician and social scientist Nicholas Christakis explains how face-to-face social networks and their structures influence behaviors and phenomena in human society and the natural living world. Originally published on March 4, 2016.

The highlands of Honduras’s Copán region, on the country’s Western border with Guatemala, remain nearly as socially isolated today as when the Mayans built one of their greatest civilizations there thousands of years ago. Far from Facebook, Instagram, or Twitter, however, researchers here are studying social networks, trying to map the true extent to which one’s connectivity can influence behavior and, more importantly, be leveraged to achieve positive outcomes.
