Retracing a Mastodon’s Steps With Chemistry

The video explores the study of mastodon tusks to understand their migration patterns, focusing on a mastodon named Fred. Researchers used strontium and oxygen levels in tusks to track Fred's movements and behaviors, revealing similarities with modern elephants. The video also discusses innovations in vaccine delivery, comparing nasal sprays and inhaled aerosols for respiratory infections. Inhaled aerosols show promise for deeper lung penetration and stronger immune responses, potentially offering a needle-free, efficient vaccination method.

What did the study find regarding the immune response of mice that received inhaled aerosol vaccines?

What are the potential benefits of inhaled aerosol vaccines compared to traditional vaccines?

Why is it important to consider inhaled aerosol vaccines for respiratory illnesses?
