Researchers have created new light-controlled tools that respond to blue light with pinpoint accuracy, offering safer, more precise treatments in the future.

Run. Red. World. Pronouncing the “r” sound in these words requires precise control of the tongue. For most children, this happens naturally, but many children struggle with residual speech sound disorder (RSSD) in which speech errors persist past the age of eight.

In a large-scale study, researchers in speech pathology tested a promising treatment approach that incorporates biofeedback—a method that uses technology to provide visual feedback to improve speech. They found that children’s ability to say the “r” sound improved at a much faster rate than with traditional methods during the early stages of therapy, demonstrating the value of biofeedback. Previous studies hinted at these benefits, but were limited by small sample sizes.

Virtual reality is emerging as a powerful tool to improve care for veterans, including helping community members recognize suicide warning signs. Researchers at The University of Texas at Arlington have conducted two studies exploring how the technology can address the complex challenges veterans face.
