Tire microplastics could fuel antibiotic resistance in urban environments

Tiny particles released as vehicle tires wear down may do more than pollute urban air, water, and soil. A new perspective article suggests that tire microplastics could create environmental hotspots that help antibiotic resistance genes persist, move between bacteria, and spread through cities.

Researchers train AI to detect diabetes and assign four diagnostic labels

Researchers developed a two-stage machine learning framework that detected diabetes and classified records as prediabetes, type 1, type 2, or type 3c diabetes using two public datasets. XGBoost showed strong internal performance, but inconsistent model rankings, non-standard variables, and the absence of external clinical validation limit immediate use.

Photoreceptors possess internal recycling system to preserve vision

For decades, scientists believed that photoreceptors in the retina relied primarily on neighboring support cells, known as the retinal pigment epithelium (RPE), to remove waste. While the RPE is still responsible for clearing away the worn-out tips of photoreceptors each day, new findings from the University of Oklahoma reveal that photoreceptors also perform much of their own internal housekeeping.
