The draft of a new study by the FDA on the safety of Bisphenol A (BPA) is a glaring example of substandard federal regulatory science that continues to place public health at risk. The study is rife with amateurish mistakes, antiquated toxicology, and a willful blindness to obvious experimental flaws that render its data and […]

So, what does early action on personal distancing and Shelter-In-Place actually get you?
This is particularly telling because, while California is less densely populated, it’s the nation’s largest gateway to China and early-on had more Chinese visitors arriving by air than any other state. More discussion about the differences here: Coronavirus: How California kept ahead of the curve.
This is the part about how you kill Grandma … and your co-workers, friends, grocery clerks, medical workers, police, fire fighters, other first responders …
People who ignore personal distancing and Shelter-In-Place orders need to get over the notion it’s all about THEM. This is about a Chicago family who tragically learned that lesson the hard way. First of all, it’s vital to keep in mind that a large percentage of people infected by COVID-19 do not show symptoms. Some […]
Mass(k) Confusion: Some masks ARE useful for COVID-19 prevention. Here’s how to tell which one is best for you. (And the science of why)
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 research!” (A Sisyphian tale … still in progress)
Based on our “back to the future” protocol revision approved by the, 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 area which included the global birth of the […]
OLD STUB-do not publish Testing BPA levels in milk: A long circuitous route sourcing dairy for the study
New confounding problem solves the two previous problems. (Sort of) While we were knock, knock, knocking on dairy’s door, the lack of cooperation from dairies and creameries combined with the inability to obtain an appropriate cream separator sent us back to our towering pile of scientific literature in search of a valid […]
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 […]
