How mRNA vaccines could change medicine as we know it

When the final Phase 3 data came out last November showing the mRNA vaccines made by Pfizer/BioNTech and Moderna were more than 90% effective, Dr. Anthony Fauci had no words. He texted smiley face emojis to a journalist seeking his reaction.
This astonishing efficacy has held up in real-world studies in the US, Israel and elsewhere. The mRNA technology developed for its speed and flexibility as opposed to expectations it would provide strong protection against an infectious disease has pleased and astonished even those who already advocated for it.

DALLAS - April 30, 2021 - UT Southwestern scientists successfully employed a new type of gene therapy to treat mice with Duchenne muscular dystrophy (DMD), uniquely utilizing CRISPR-Cas9-based tools to restore a large section of the dystrophin protein that is missing in many DMD patients. The approach, described online today in the journal
Science Advances, could lead to a treatment for DMD and inform the treatment of other inherited diseases.

For more than 15 years, researchers at The University of Texas at Dallas and their collaborators in the U.S., Australia, South Korea and China have fabricated artificial muscles by twisting and coiling carbon nanotube or polymer yarns. When thermally powered, these muscles actuate by contracting their length when heated and returning to their initial length when cooled. Such thermally driven artificial muscles, however, have limitations.
