The Persistence length of dsRNA is an interesting thought.
4.2kb is about 1um in length. 43T of these is 43,730 kilometers.
The Circumference of the Earth is ~40,000km.
A 100ug injection is enough degradation resistant RNA in your body to circle the Earth. Image
Caveat... The shot is 99+% ssRNA (in theory) which has a shorter persistence length since it folds on itself but for illustrative purposes, dsRNA is shown. The 4.2Kb is the length of the ssRNA in the shot.

This school is a disgrace.
@MiddlesexSchool
Why don’t you recognize the Covid recovered?

How does it feel to be discriminatory towards people who recovered from C19 and have better immunity than your cultish obsession over a vaccine that doesn’t stop transmission?

Woke cult. Image
I once donated my time to present genomics to your students.

Never again will I help your discriminatory school.
Over 150 articles that demonstrate the Covid recovered have better immunity than your experimental liability free vaccine that doesn’t stop transmission.

How can a school be this dumb?

Or are you too woke to read new data?

The Antartica metagenomic samples that @jbloom_lab nicely covered has some quirks.
NCBI claims its Illumina Data
Fastq files have headers that look like MGISeq data.

So I decided to take a look at their Adaptor sequences as each sequencer has their own unique flow cell primers
TrimGalore indeed confirms these are MGISEQ reads.
This paper has the MGISEQ adaptor sequences-
frontiersin.org/articles/10.33…
Why does this matter? The authors posit that this could be a result of the high index hopping problem seen on Illumina platforms.
MGISEQs documented index hopping rate is orders of magnitude lower than Illumina.

Psilocybe cubensis assembly in NCBI.
This couldn't be done without @PhaseGenomics or @PacBio

These HiC maps were performed on spores which express no controversial compounds.
Illumina libraries are also generated with spore preps.

Carl Fuller et al are at it again.

This is wild. 16,384 CMOS chip capable of single molecule movies at each pixel.

Each pixel has a protein nanowire bridging it. These are assembled with electrophoresis.

Once wired, click chemistry binds one molecule.

20nM gap for the nanowire peptide bridge.

1000Hz read outs. 0-400pAmp sensors.

Many people ask me about this Moderna patent sequence.

Some calc the odds of a 19mer by chance as 4^19.
A big number if life were truly random.
But evolution is a preservation of those random words that improve fitness so we have to ask, are there similarities to common words?
Take the 19mer sequence and plug it into NCBI BLASTn against the Nr database.

Check ‘exclude’ and enter coronaviridae.

You’ll get microbial hits like this.

Check the E-Value.
What’s the E-Value?
Q: What is the Expect (E) value?
The Expect value (E) is a parameter that describes the number of hits one can “expect” to see by chance when searching a database of a particular size. It decreases exponentially as the Score (S) of the match increases.

If you read the Corman Drosten retraction demand addendum, you will see we voice concerns over both FN and FPs.

A common newb retort is that the test can’t have both.
On an individual test this is true but on a population level this is false.

pubmed.ncbi.nlm.nih.gov/34741305/
So why do we only hear debate about the FP rate?

I believe this is because the implications of FPs are less severe than the implications of FNs.

FPs you can confirm with another test or just suck it up and quarantine for the ‘greater good’.
FNs, on the other hand, expose the entire track trace system as the scam that it is.

Particularly when they are this high.
Once negative, very few people want to stand in a line with other potentially sick people and pay $50-300 a second shot at quarantine.
