The acoustic niche hypothesis.

Sounds in the jungle or forest are not a cacophony of cluttered noise but a lush musical harmony. 

Creatures evolved to make sounds in different rhythms and pitches so as not to interrupt each other. 

Many creatures need to hear and be heard in order to find food, water, mates. And it's best to do that without wasting energy.

So they evolved over millions of years to be able to all make sounds together but without interrupting each other. 

It's like evolution, brutal a rap as it gets, actually forged a sonic civility.

They're trying to find that niche [amongst the cacophony of sound] which is a clear channel of communication so that their voices can be heard.

Bernie Krause and Stuart Gage developed the acoustic niche hypothesis, posing that creatures sharing an ecosystem evolved to make sounds in different rhythms and pitches so they don't get in each other's way.

Chef's Table S 1: Ep 2

"John Gold wrote a review that defined who we were before we even knew it ourselves"

"Farm to table is an old way of eating."

We're a nation of immigrants, and when we first came here we had abundance like no one had ever seen.

Great cuisine comes out of hardship, they were all forced into a negotiation between peasants  and their environment. That's a real tragedy. You have the recipe for what is American cuisine today, because everything grew in abundance. 

"Not great ingredients in large abundance."

"Every chef I know that’s successful has had moments of just really intense failure.”

Why are hot water taps always on the left?

"back in the 19th century, when indoor plumbing was introduced, water was generated by a hand pump...since most people...are right-handed, the pump was placed on the right side of the sink...

"why are toilet flush handles on the left? ...Early indoor toilets had pull chains connected to overhead water tanks... located…[on] the right from your on-the-throne perspective."

Covid-19 - Decontamination of N-95 masks APSF

"Although Covid-19 virus is ~ 0.1 µm in size, the exhalation droplets can be several micrometers or larger but shrink while traveling in air due to water evaporation..."N95 respirator ...>98% efficient at Covid-19 virus size of ~ 0.1 µm."Figure 1, N95 respirator has greater than 95% efficiency over the entire size range...and is greater than 98% efficient at Covid-19 virus size of ~ 0.1 µm... steam heat treatment caused slight efficiency drop (less than 5% on the average) on surgical masks after 10 treatment cycles"

Coronavirus symptoms

chills, repeated shaking with chills, muscle pain, headache, sore throat, and new loss of taste or smell. This is in addition to the previous official symptoms: fever, cough, and shortness or breath. These symptoms may appear 2-14 days after exposure to the virus.

Marvelous Mrs. Maisel - Cinematography of the Long Take

Shoes are fomites

I never really thought about where all those nasty COVID droplets in the air end up - the floor. I was so preoccupied with hand washing. 

Footwear: The CDC released a study suggesting that infection prevention strategies regarding footwear might be helpful when responding to the COVID-19 pandemic.

• The floor is always considered contaminated.
• Practices to consider include:
  • Placing the lower half of a cardboard box in trunk/car and changing out of work shoes that have been worn in the hospital before entering the car to drive home or elsewhere.
  • Removing shoes in the garage and not taking them into the house.
  • When arriving at the parking lot for work, removing work shoes from the car and changing into them.

COOSF mutant enzyme breaks down plastic

"The mutant enzyme broke down 90% of 200 grams of PET in a small reactor in just 10 hours."

"The enzyme cannot be added to waste plastic until it is ground up and melted, however, so the recycled PET is still more expensive than virgin plastic."

Clean your N-95 mask in the microwave

There's a Stanford website that describes ways to process N-95 masks in your microwave for reuse. 

Here is the website:

www.N95decon.org

Here's the CDC guidance on how to clean them for reuse:

"Steam treatment may be a suitable approach for decontaminating FFRs. The limited number of studies for steam report minimal effect on FFR filtration and fit performance and a minimum 99.9% reduction in H1N1 and bacteriophage MS2 [14, 15]. Fisher et al. used microwave steam bags, designed for disinfecting infant feeding equipment, to decontaminate six FFR models and achieved 99.9% inactivation of MS2 bacteriophage. Filtration performance of all tested FFRs scored above NIOSH certification requirements. Three FFRs were further evaluated for three cycles of steam exposure and demonstrated no change in filtration performance [15]. Bergman et al. also demonstrated acceptable filtration performance after three cycles of exposure to microwave generated steam [3]. Microwave generated steam had little effect on FFR fit after exposure to up to three cycles of steam [9, 10]. Using microwaves to produce steam to decontaminate FFRs is not without limitations. Not all microwaves are constructed the same and some are more powerful than others. The effect of higher power microwaves on FFRs is unknown. Furthermore, the metal nosebands of FFRs may cause arcing, sparks inside the microwave oven, during exposure to microwaves."
