Studying epidemics can help us plan for the future and identify better ways of dealing with them. Now, in a new study published in the Proceedings of the National Academy of Sciences, a multi-institutional research team led by the Institute of Industrial Science, The University of Tokyo, has worked...

How many people will travel during a given week between two specific cities? Answering this question is important for many reasons, for example, to design efficient public transport infrastructures, or, as was the case during the COVID-19 pandemic, to understand how mobility patterns could be used...

When you look at your surrounding environment, it might seem like you're living on a flat plane. After all, this is why you can navigate a new city using a map: a flat piece of paper that represents all the places around you. This is likely why some people in the past believed the Earth to be flat....

You can learn a lot from a little slime mold. For Nate Cira, assistant professor of biomedical engineering in Cornell Engineering, the tiny eukaryotic organism provided inspiration for modeling "traveling networks"—connected systems that move by rearranging their structure....

Elections are a well-documented example of collective human decision-making, with voting data available for elections globally over several decades. SFI Complexity Postdoctoral Fellow Aanjaneya Kumar, along with former colleagues at the Indian Institute of Science Education and Research (IISER)...

A game of chess requires its players to think several moves ahead, a skill that computer programs have mastered over the years. Back in 1996, an IBM supercomputer famously beat the then world chess champion Garry Kasparov. Later, in 2017, an artificial intelligence (AI) program developed by Google...

The math that describes the branching pattern of trees in nature also holds for trees depicted in art—and may even underlie our ability to recognize artworks as depictions of trees....

During the Super Bowl, every decision matters. With millions of fans watching, the game often comes down to a single play call. And no call is more scrutinized than what a coach decides to do on fourth down. Punt? Attempt a field goal? Or go for it?...

The collective motion of large crowds may be predictable past a certain density of people in a given area, according to a study published in Nature. The findings, based on four years of observations at a traditional Spanish festival, offer insights that could help to predict dangerous crowd behavior...

In India, many kids who work in retail markets have good math skills. They can quickly perform a range of calculations to complete transactions. But as a new study shows, these kids often perform much worse on the same kinds of problems as they are taught in the classroom. This happens even though...
