odds. but for the most protection, wearing an n 95 or kn 95 was associated with 83% lower odds. and that s compared with wearing no mask at all. now, i spoke with an expert on aerosol particles about this, and he tells me if everyone else is unmasked, those percentages could go down, because more particles from the unmasked people could release into the air. but the bottom line, if your mask is on, that mask can still filter particles offering some protection. boris, christi? thank you for that. a new study from providence healthcare system shows unvaccinated people developed the same amount of protection of reinfection as those who have been infected. but as dr. sanjay gupta explains, it is not that simple. at this lab in emory university, this scientist is working to answer one of the
Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to .
