New MRI technique enables long-term tracking of transplanted stem cell-derived heart cells

University of Toronto Faculty of Applied Science & Engineering
Peer-Reviewed Publication

Researchers at the Institute of Biomedical Engineering at the University of Toronto have demonstrated a new way to monitor transplanted stem-cell-derived heart cells using magnetic resonance imaging (MRI). 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.

These AI-powered guide dogs don’t just lead – they talk

Binghamton University
Reports and Proceedings

Guide dogs are powerful allies, leading the visually impaired safely to their destinations, but they can’t talk with their owners — until now.

Using large language models, a team of researchers at Binghamton University, State University of New York has created a talking robot guide dog system that determines an ideal route and safely guides users to their destination, offering real-time feedback along the way.
