Story summary

Massachusetts Institute of Technology (MIT) engineers developed a programmable drug-delivery patch for bypass surgery that reduces damaged heart tissue by 50% and improves cardiac function in rats.
The patch dissolves over time and increases survival by 33% versus traditional treatments.
Researchers plan further animal testing before pursuing human trials.
University of California, Berkeley researchers have created a heart-on-a-chip model to identify lipid nanoparticles for delivering mRNA therapies into heart cells.
