CRISPR gene-drive technology reverses antibiotic resistance in bacteria

Antibiotic resistance (AR) has steadily accelerated in recent years to become a global health crisis. As deadly bacteria evolve new ways to elude drug treatments for a variety of illnesses, a growing number of "superbugs" have emerged, ramping up estimates of more than 10 million worldwide deaths per year by 2050.

Early biomarkers predict infections after breast reconstruction surgery

In the U.S., one in eight women will get breast cancer in their lifetime, and about half of them will have mastectomies.

New guidance on diagnosing UTIs without an in-person exam

Researchers developed criteria for triaging suspected UTIs, focusing on antibiotic use and urine testing to improve outpatient care and telehealth efficiency.

Ancient ice and modern pollution combine to spread antibiotic resistance as glaciers melt

Glaciers harbor both ancient and human-derived antibiotic resistance genes, preserved in ice and increasingly mobilized by climate-driven melt. This global review proposes a glacier-to-downstream “continuum” to understand how resistance genes may move through connected freshwater ecosystems.
