What if you were holding life-saving medicine ... but had no way to administer it? Zoom down to the nano level with engineer Kathryn A. Whitehead as she gives a breakdown of the little fatty balls (called lipid nanoparticles) perfectly designed to ferry cutting-edge medicines into your body's cells. Learn how her work is already powering mRNA-based COVID-19 vaccines and forging the path for future therapies that could treat Ebola, HIV and even cancer.

Kathryn A. Whitehead: The tiny balls of fat that could revolutionize medicine

The tiny balls of fat that could revolutionize medicine

Lipid nanoparticles, the unsung heroes behind mRNA vaccine efficacy, encapsulate and deliver life-saving instructions to our cells.

Lipid nanoparticles, akin to a Trojan horse, smuggle mRNA into cells, revolutionizing vaccine delivery and future medicine.

mRNA vaccines, taught our cells to combat COVID, now pave the way for targeting diseases like cancer and cystic fibrosis.
