Germany, India, Mexico, and Spain. As multiparty democracies, these countries present a more complex picture of what brings people together—or divides them. Using social media data, a group of researchers proposes a novel approach to measuring polarization in nations with multiple political parties.

Complexity Science Hub scientist Samuel Martín-Gutiérrez and his colleagues developed a model that infers opinions from social networks, and measures the left-right political division, as well as other more nuanced sources of tension. They analyzed Twitter data from the Spanish elections of 2015 and 2019.

“It’s important to understand polarization in our society, and our findings shed new light on how political beliefs are shaped,” says Martín-Gutiérrez. “Our approach can lead to useful insights when applied to real-world debates happening on social media.”

Major changes in the spinal columns of mammals have been shaped by their highly variable numbers of vertebrae, according to new evidence from a team of international scientists, including researchers from the Milner Center for Evolution at the University of Bath.

The team unearthed new findings that identify how this column “complexity” in mammals has been shaped by their varying numbers of vertebrae.

The research group from the University of Lincoln, U.K., the University of Bath and Nanjing Institute of Geology and Paleontology, China, conducted a case study that examined the vertebrae of 1,136 modern mammal species, ranging from blue whales to shrews, to determine how column complexity evolved within major groups over time.

We posed these questions to GPT-4:

How can we address the often wide gap in perception of reality and adherence to the laws of the physical world when so many people prefer to imagine their afterlife instead of focusing on the life they are living now?

What are your thoughts on the viability of religion to provide people guidance during exponential times such as we are in now?

Microsoft’s text-to-speech model VALL-E can mimic anyone’s voice with little training data. Now it can do so across languages while replicating emotion.
