The method allows researchers to visualize where transplanted cells survive over time, which could help scientists evaluate and improve emerging stem cell therapies for heart damage such as those caused by heart attacks. Professor Hai-Ling Margaret Cheng and her team have shown that an imaging platform known as "bright ferritin MRI" can be used to track transplanted human pluripotent stem-cell-derived cardiomyocytes in the hearts of rats for up to eight weeks. The findings are published in Magnetic Resonance in Medicine. https://medicalxpress.com/news/2026-04-mri-technique-enables-term-tracking.html Wed, 08 Apr 2026 17:20:02 EDT news694882911 Researchers at NYU Abu Dhabi have developed smart molecules that can both detect and treat cancer, offering a safer and more precise approach to care. The research, published in the Journal of the American Chemical Society, focuses on magnetic resonance imaging (MRI), a widely used tool that allows doctors to see tumors inside the body. While MRI agents are commonly used for diagnosis, they do not typically play a role in treatment. The NYU Abu Dhabi team designed molecules that combine both functions in a single system. https://medicalxpress.com/news/2026-04-smart-mri-molecules-cancer.html Tue, 07 Apr 2026 17:20:03 EDT news694796521 Lung cancer remains the leading cause of cancer-related deaths worldwide, accounting for nearly one in five cancer deaths—around 1.8 million lives lost each year. One of the main reasons is late diagnosis: in its early stages, the disease appears as extremely small nodules that are difficult to distinguish from healthy tissue, even for experienced radiologists. https://medicalxpress.com/news/2026-04-ai-doctors-lung-cancer-earlier.html Tue, 07 Apr 2026 11:40:03 EDT news694779241 Sleep helps the brain to cleanse itself—and now this process can be measured in humans entirely noninvasively.
