Any common face mask provides significant protection against the virus that causes COVID-19, but N95 masks are most effective at slashing the amount emitted by infected people, according to a University of Maryland-led study released Wednesday.
So-called “duckbill” N95 masks scored highest in the study, which measured the exhaled breath of participants who were tested both masked and unmasked to measure comparative outputs of SARS-CoV-2. The inexpensive masks, which have two head straps and a horizontal seam, captured 98% of exhaled virus, according to the study published in eBioMedicine.
The researchers also found that—in what might come as a surprise to many—cloth masks outperformed the specific brand of KN95 mask that was tested. Surgical masks brought up the rear in performance out of the four types, but even they blocked 70% of the virus, the tests showed. (To reflect the general public's use of masks, study volunteers were not fit-tested for their masks or trained how to properly wear them.)
“The research shows that any mask is much better than no mask, and an N95 is significantly better than the other options. That’s the No. 1 message,” says the study’s senior author, Donald Milton, a professor of environmental health and a global expert on how viruses spread through the air.

When I was little I thought the rainbow goes “Red Orange Yellow Green Blue Tilapia Purple”
The word “nila” in my mother tongue translates to both “tilapia 🐟” and “indigo (colour)”. My mom worked in seafood, and she gave me the wrong English word when I asked.

I love when translators get to write a foreword and 9 times out of 10 it's just "I'm sorry for my inadequate translation but human language is so problematic"

in guarani there's a standard greeting that literally translates to "are you happy" (ndevy'apa) and the natural reply is "i'm happy" (avy'a) and as americans learning the language we were so distressed like "but what if we're not happy....." and our teachers were like "that's so not the fucking point"
we kept trying to think of any other way to reply but our teachers kept trying to get it into our brains that it's an idiomatic greeting, it literally is not the time or place to traumadump, and as usamerican english speakers we are not some special exception for saying "what's up" with the reply being "not much" instead of "the ceiling"
but anyway while i was working in paraguay -- the country with the largest population of guarani speakers -- i got sent an article by some friends back home like "look! they're saying that paraguay is the happiest country in the world!"
and the methodology was "we went around and asked paraguayans if they're happy and recorded their responses" and i was like. oh. of course you did. and of course you got a 100% positive response rate.
wait. cancel post. gung-ho cannot be English. where did that phrase come from? China?
ok, yes. gōnghé, which is…an abbreviation for “industrial cooperative”? Like it was just a term for a worker-run organization? A specific U.S. marine stationed in China interpreted it as a motivational slogan about teamwork, and as a commander he got his whole battalion using it, and other U.S. marines found those guys so exhausting that it migrated into English slang with the meaning “overly enthusiastic”.
