Novel method for measuring spatial dependencies turns less data into more data

The identification of human migration driven by climate change, the spread of COVID-19, agricultural trends, and socioeconomic problems in neighboring regions depends on data—the more complex the model, the more data is required to understand such spatially distributed phenomena. However, reliable data is often expensive and difficult to obtain, or too sparse to allow for accurate predictions.

A flexible color-changing film inspired by chameleon skin

Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a flexible film that changes color in response to stretching, pressure or humidity. They report their results in ACS Applied Materials & Interfaces.
