Effect of Atmospheric Dust on Ice Cloud Formation Confirmed
It is known that the proportion of ice-topped clouds depends on dust particles in the cloud that act as nuclei for ice crystal formation............

#Influenza virus #infection and #aerosol #shedding kinetics in a controlled #human infection #model

Source: Journal of Virology, ABSTRACTEstablishing effective mitigation strategies to reduce the spread of influenza virus requires an improved understanding of the mechanisms of transmission. We evaluated the use of a controlled human infection model using an H3N2 seasonal influenza virus to study critical aspects of transmission, including symptom progression and the…

Derk et al, 2023: CR boxes out-performed single-filter DIY air filtration units. 5cm-thick #MERV13 filters out-performed 2.5cm ones. Best #CRbox config. reduced #aerosol exposure to 22% that of HVAC units alone. Adding universal masking reduced it to 6%. https://www.reddit.com/r/COVIDZero/comments/106647p/derk_et_al_2023_cr_boxes_outperformed/

#Aerosols in indoor air can vary in #acidity & the #acidity determines how long viruses remain infectious in the air. New research study from ETH Zurich, EPFL and University of Zurich shows how the pH of #aerosol particles changes in the seconds and hours after #exhalation under different #environmental #conditions. It also shows how this affects the #viruses contained in the #particles. The study appears in the journal Environmental Science & Technology. #Flu #Covid https://www.futurity.org/aerosols-acidity-viruses-2848802-2/
