This will go down in history as one of science and medical research's greatest achievements. Perhaps the most impressive.
I put together a preliminary timeline of some key milestones to show how several years of work were compressed into months. Image
There are several points noteworthy related to this timeline:
1. Moderna had a head-start, so why didn't their Phase 3 trial finish first?
Part of #OperationWarpSpeed (OWS), they were requested to slow down enrollment to get better minority representation

2. 3 scientists led the way
Katalin Karikó, worked on a mRNA vaccine for ~30 years, was demoted from @PennMedicine d/t losing her grants, went to @moderna_tx

and the husband and wife team @BioNTech_Group

3. The 5 days from sequencing the virus to design of an mRNA vaccine, relayed by Tony Fauci in our conversation
@Medscape Image
4. Whose idea was OWS and when did it kick in?
Peter Marks @US_FDA

It was announced May 15th

Most people haven’t heard of this test, which is available in the US. It accurately predicts Alzheimer’s (not just if there’s a risk, but when). It is favorably affected by exercise and likely many other lifestyle factors.
Here’s (almost) everything we know about it. In Ground Truths (link in my profile d/t X-suppression)Image
Here's the response to exercise Image
The most sensitive and accurate biomarker to date Image

A major @Nature paper this week found a significant decline in dementia after an outdated Shingles vaccine.
I've reviewed the study and many other relevant ones in a new Ground Truths (link in profile) Image
A Table from the post Image
The effect in the 2 natural experiments differed substantially by sex with the benefit predominant in women Image

Of >105,000 participants with 30-year follow-up, only 9.3% achieved healthy aging (age 70, w/o any chronic diseases). Their diet was significantly associated with this outcome🧵 @NatureMedicine Image
These are the specific foods that were linked with healthy aging and other outcomes. Green-favorable; Red-unfavorable Image
Adherence to these diets (most to least in quintiles) linked to healthy aging Image

A paper on microplastics accumulating in the brain was just published @NatureMedicine, open-access
I review the background and major implications in a new Ground Truths edition (link in my profile)nature.com/articles/s4159…Image
Image
The human brain:
—had 7-30 times more accumulation of microparticles (MPs) than the liver or kidney (organs with previously documented high propensity)
—from people with dementia had 5X accumulation of MPs compared with non-dementia
—there was a marked increase of accumulation over recent years

Three new @NEJM reports on #H5N1 today
1. An overview by @MichaelGIsonMD and @DrJeanneM
"urgent need for vigilant surveillance of emerging mutations and assessment of the threat of human-to-human transmission" Image
