New technology makes internet memes accessible for people with visual impairments

People with visual impairments use social media like everyone else, often with the help of screen reader software. But that technology falls short when it encounters memes, which don't include alternate text, or alt text, to describe what's depicted in the image. To counter this, researchers at Carnegie Mellon University have developed a method to automatically identify memes and apply prewritten templates to add descriptive alt text, making them intelligible via existing assistive technologies.

From firearms to fish -- following patterns to discover causality

Mathematicians have successfully applied a new, pictorial approach to answer complex questions that puzzle analysts, such as, do media stories on firearm legislation influence gun sales? Cause-and-effect queries like this pop up in various fields, from finance to neuroscience, and objective methods are needed to deliver reliable answers. The team of researchers wrestled mathematical theory into quantifiable colorful maps called symbolic recurrence plots, and in this week's Chaos, they have proven the method's validity.

Industrial bread dough kneaders could use physics-based redesign

When making bread, it's important not to overknead the dough, because this leads to a dense and tight dough due to a reduced water absorption capacity that impairs its ability to rise. But bakers also want to avoid underkneading, because this decreases the gas retention capacity. Researchers have now explored the local mechanical and microstructural changes that occur during different stages of the kneading process via numerical simulation.
