If and when effective vaccines for Covid-19 are developed, some will surely rely on a nanoparticle delivery system whose origins lie in decades of painstaking groundwork. Offering a tour of that effort was Dr. Dan Anderson of MIT.
As Covid-19 began spreading in the United States, NIDDK scientists began studying how people might be transmitting the virus through speech. Their research revealed that normal talking disperses thousands of saliva droplets that can linger in the air; wearing a cloth mask dramatically helps prevent their release.

Gene therapy could soon provide a treatment for patients with hearing loss and dizziness, said Dr. Wade Chien.
