#NASA launches a billion-dollar #Earth science mission Trump tried to cancel
“It has been a long, strange trip," says the top scientist on #PACE, which stands for Plankton, Aerosol, Cloud, ocean Ecosystem. This mission will study #phytoplankton, microscopic #plants fundamental to marine #foodchain, and tiny particles called #aerosols that play key role in cloud formation. Scientists say PACE will try to fill in some gaps in their understanding of #climatechange. https://arstechnica.com/space/2024/02/trump-tried-to-kill-it-but-nasas-new-climate-satellite-is-finally-in-orbit/ #climate

Back to today, '#airborne transmission of pathogens has been vastly underappreciated, mostly because of insufficient understanding about airborne behaviour of #aerosols, and because of the misattribution of anecdotal observations'. @linseymarr et al. @NCBI

Media should ask public health how measles virus transmits

With all the attention on #measles #outbreaks recently, the media should ask public health how the measles# virus can catch a ride in #aerosols to help it stay #airborne for hours and infect people but somehow no other virus like #COVID or #respiratory viruses (#Flu, #RSV) can use the exact same transportation method and fall to the ground. 🤔🧵 1/

Infectivity of exhaled #SARSCoV2 #aerosols is sufficient to transmit #covid19 within minutes

https://www.nature.com/articles/s41598-023-47829-8

Although just published today, this is from Feb-March 2021, 7 months before the very first #omicron that was more infectious & 12-16 months prior to super infectious BA.5

So… my guess is, one can get enough infectious dose with 1-2 inhales. We are truly down to mere seconds #viralDose

& nearly nobody cares

Yeah, I’m not waiting for science studies for confirmation of what I’ve already known for years now
