If you’ve ever been dumbfounded by a Covid-19 rule that seems to go against everything you ever read in PubMed then this article is for you, Baby! 👆👆👆👆
Covid-19 policies have banned:
- open-toed shoes
- bars after 10pm (but not before)
- parks and playgrounds
Surprise! If you are reading this tweet and past puberty, your thymus gland -- which harbors the T cells that help train the body to make protective antibodies against new viruses (and respond to vaccines) -- is already shrinking: nationalgeographic.com/science/2020/0…
Almost a century ago, Edith Boyd helped confirm that the thymus shrinks with age. Boyd was an anatomist who combed through data from 10,000 autopsies collected at the University of Minnesota and compared them to similar findings from European scientists: nationalgeographic.com/science/2020/0…
THREAD🧵--> For weeks, I've been tracking the scientific debate about whether we need masks to prevent transmission of the virus causing #COVID19 and whether it is #airborne. If you're confused, you are not alone. Stick with me here. Let's clear the air. 1/15
On Saturday, the World Health Organization used CAPS to say, "FACT: #COVID19 is NOT airborne." Here is the tweet. But keep reading this thread, because the wording is tricky.
As I wrote about 2 weeks ago, essentially, the word 'airborne' means something traveling in the air. But public health officials rely on a cutoff that any tiny bit of mucus larger than 5 microns in diameter that you cough out is called a 'droplet' 3/15 wired.com/story/they-say…
THREAD --> In this time of #COVID19, I figured it might be handy to share some basics with other reporters who might be new to the health beat. What's an 'antibody'? What is 'viral load'? Here's a list of some things reporters might want to know. I'm adding to it slowly.
First off. A lot of the tests being discussed are looking for 'antibodies'. What the heck are those? In a nutshell, proteins made by certain immune cells that bind to particles in the body (usually foreign) that we call 'antigens'. Here's a 3:28min primer:
What's that? You're a reporter too busy to watch a 3:28min video? I understand. Here's a picture capturing pretty much the same thing 3/n (source: slideplayer.com/slide/9390892/)
I don't think it captures preprints (meaning papers that have not undergone peer review), but it is really a great hub to bookmark if you are a reporter living in the year 2020.
