Biomedical engineers from Brown University have developed a new wound dressing material that releases antibiotic drugs only when harmful bacteria are present in a wound. In the new study, published in the journal Science Advances, the researchers show that the material could help rapidly clear wound infections to accelerate healing while reducing the unnecessary use of antibiotics—a major driver of antibiotic resistance and hard-to-treat “superbug” infections that claim tens of thousands of lives worldwide each year.

Scientists from Great Ormond Street Hospital (GOSH) and University College London (UCL) have created the first lab‑grown esophagus—the food pipe—shown to safely replace a full section of the organ and restore normal function, including swallowing, in a growing animal without the need for immunosuppression.

Researchers at Graz University of Technology (TU Graz) have developed a novel virtual reality (VR) system that could make the treatment of arachnophobia, also known as spider phobia, more targeted and personalized in the future. The work is published in the journal Frontiers in Human Neuroscience.

Dartmouth researchers have developed a cell phone-based tool that monitors tissue health by using a naturally occurring molecule to measure the oxygen level in cells.
