It’s important to realize that hand to face contact is a serious avenue of infection spread which is best addressed by frequent hand washing and avoiding face touching. However, the Coronavirus can spread through the air, through aerosols or contaminated dust particles. Early on in the pandemic, experts were adamant that masks were not effective […]

Updated 4/18/20 – How 2 Billion pennies explain why social distancing is so vital to defeating COVID-19 (And not killing Grandma)
Note: This article was updated April 18, 2020 These two exponential/geometric growth charts look a lot alike. But they represent two very different things. To understand, first imagine you are owed a great debt. The person who owes you money gives you a choice, but you have to respond right then. Choice #1: $1 million […]
Coronavirus/COVID-19: Face masks actually CAN help. Also beware the threats from restroom hand dryers, poop & toilet flushing
Note: proper-frequent hand-washing and other public health warnings should be followed, but there exist other significant considerations that can add to those. Several of those, are below, along with links to peer-reviewed scientific papers (and a couple of well-sourced articles from the media and government sources) H0w masks can help protect you against COVID-19 Like […]
Micro- and Nanoplastics: Background
Microplastics are generally those fragments that are less than five millimeters in size. However, a single microplastic fragment rarely stays the same size. Whether found on dry land, in steams and oceans — or in your mouth as you chew, swallow and digest — natural and biological forces relentlessly reduce microplastics in size. Eventually, […]
No Milk For A Scientific Study! + How researchers almost bought a cow.
Based on our “back to the future” protocol revision approved by the University of California San Francisco Medical School, , we began to contact dairies, creameries, farm organizations, and agriculture-related educational institutions. We assumed that obtaining raw milk would be relatively easy given that the study’s investigators lived and worked in the San Francisco Bay […]
As terrible as those plastic-polluted ocean photos are, your body is a SERIOUSLY more contaminated by the same chemical garbage
You are the ocean. You are — on average — about 65% water. Your blood vessels flow with a saline solution with chemical properties that ares eerily similar to sea water. Your heart imitates the cadence of waves on a beach — a sound many people find comforting, especially those that keep time with a […]
Why plastic isn’t just plastic (and most can’t be trusted)
NOTE: This is adapted from Appendix 3 of the “Revised Stealth Syndromes Study Protocol as approved by the University of California San Francisco Medical School Committee on Human Research. Plastic chemicals contaminate our food because plastic isn’t just plastic. Instead, what we see as plastic is a mixture of one or more polymers along with […]
Why “BPA Free” is a meaningless marketing scam (And some plastic safety claims are false)
BPA substitute Tritan found to cause estrogenic activity: Migration of plasticisers from Tritan ™ and polycarbonate bottles and toxicological evaluation Estrogenic chemicals often leach from BPA-free plastic products that are replacements for BPA-containing polycarbonate products Chemicals having estrogenic activity can be released from some bisphenol A-free, hard and clear, thermoplastic resins In addition, the number […]
The math behind the ocean/human plastic contamination concentration
Geek note: mass and weight are not the same thing. Mass is a measurement of how much matter is in something. Weight is a measure of the pull of gravity on mass. That’s why an object on the moon weighs 1/6 that of that same object on the earth.(And why astronauts on the space station […]
Radiation, Ebola, lice, bedbugs, ticks & BPA: No matter how hard you try, you can’t avoid plastic chemicals
Risk = concentration + frequency. Radiation, Ebola, lice, bedbugs ticks and Bisphenol A (and other plastic chemicals) have a fair amount in common. Fortunately, you can choose to avoid five of those six, but the third gets forced upon you every minute of every day. First, they are all alike because the damage they can […]
