Novel microneedle patch accelerates healing of chronic diabetic wounds using light

by

Researchers from Nanjing Drum Tower Hospital, Southeast University, and Wenzhou Medical University have developed a novel microneedle patch that combines MXene hydrogel with nitric oxide (NO) and hypoxia-inducible factor-1α (HIF-1α) plasmid for enhanced diabetic wound treatment. This study, published in the journal Engineering, presents a promising approach to addressing the chronic and non-healing wounds often … Read more

Scientists build world’s most accessible gut bacteria collection to unlock health and disease clues

New RNA barcoding method tracks gene transfer in microbial communities

by

In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive antibiotic resistance and even shape entire ecosystems. Now an interdisciplinary group of researchers at Rice University has developed an innovative RNA “barcoding” method to track these genetic exchanges in microbial communities, providing new insights into how genes … Read more
