A new study from Peking Union Medical College Hospital finds that robot-assisted cerebral angiography using China’s YDHB-NS01 system achieved a 100% success rate and significantly shorter procedure times than manual methods, without increasing radiation exposure, contrast use, or complications. This prospective study provides real-world clinical validation and highlights the potential of robotic systems to reduce occupational radiation risks in neurointerventional surgery.

After years of research, international experts have confirmed the discovery of a new chemical reaction, launching new opportunities for rapid advances in a range of fields – from recycled plastics to pharmaceuticals.

In a major new article to be published in top-ranking journal Nature Chemistry, the interdisciplinary team explore how sulfur-sulfur bonds can be formed and broken rapidly and cleanly at room temperature, opening new avenues for drug development, biotech and protein science, and chemical and material science.

Researchers studied wild Northern cardinals to see how everyday challenges shape the gut microbiome. Even brief disruptions, like short handling or rival interactions, triggered microbial changes linked to stress hormones, body condition and beak coloration. Birds with the largest microbial shifts also showed pronounced physiological and visual stress responses, highlighting the gut microbiome as a sensitive indicator of health. The study reveals how subtle, routine stressors influence internal biology, offering new insights into how wild animals maintain resilience and cope with environmental pressures.
