1) Before you can hear anything, a sound must be created. In the case of the voice, this happens when speaking. The sound waves that we generate with the larynx and articulate with the mouth, especially the tongue, are wave-like vibrations in the air. What a person is saying can
2) therefore be heard because the vibrations reach the eardrum via the air. This is called air conduction. The resulting vibration sets the eardrum in motion, which causes the oscillations to be transmitted to the inner ear via the ossicles.

@JoeBiden At this moment, let’s do science!

COVID19 Deaths: 203,180 (covid.cdc.gov/covid-data-tra…)

Cardiovascular Deaths: (23,328,000 [timeanddate.com/date/durationr…] ÷ 36 [cdc.gov/heartdisease/f…]) = 648,000

You’re 3.1893-times more likely to die of heart disease than COVID.

Let’s do more science!

The mean mass of the Earth’d dry air mass is x̅5.1352 × 10¹⁸ kg. (journals.ametsoc.org/jcli/article/1…)

That’s: 5,135,200,000,000,000,000 kg
The permanent gases whose percentages do not change from day to day are 78% nitrogen, 21% oxygen and 0.9% argon.

Trace gases like carbon dioxide, nitrous oxides, methane, and ozone account for 0.01%, of the Earth’s atmosphere. (climate.ncsu.edu/edu/Composition)

🧵1-A thread for non-scientists on the issue of #COVID19 variant (614G vs. 614D) found most common in Québec (614G) & why it's irresponsible & inaccurate to blame the way pandemic unfolded in Québec on the variant

#scientific evidence shows this variant is NOT more dangerous
2-The phylogenetic analysis of #COVID19 in Québec has shown that majority of viral introductions to the province came from Europe ()
Therefore the variant (version of the virus) that was most common is Europe (614G) is also most common here
3- Wondering what D614G means:
genome is a long code that gets translated to functioning molecules. To keep track of each letter in the code, we assign them a number based on their position, hence 614. D&G refer to 2 molecules that different versions of the code can produce.

🧵In this thread I'll address the INACCURATE claim that the #COVID19 strain found in Québec is somehow more virulent & therefore the reason Québec was the epicentre of the pandemic in🇨🇦
I'll be referring to data from @McGillGenome study & @nextstrain

1st I'd like to acknowledge @bjesseshapiro @cl_murall & other amazing #scientists whose work & analysis should be relied on by policy makers & media alike.

See my summary of their phylogenetic study of #SARSCoV2 in Québec 👇🏾
2/11
Analyzing samples from 734 Québec residents shows a global introduction of the virus into Québec. However, once the borders were closed & restriction were put in place, certain clades of the virus become more frequent.
What is a clade you ask? good question, keep reading👇🏾

OK, #Canadian scientists, #science students, science influencers, scientific societies, student & postdoc unions, and everyone else who may know someone w/ science postgraduate training

We (@COVID_19_Canada ) and the province of #Ontario really need your help...every one of you.
Ontario needs to hire and train hundreds of people to work in #COVID-19 testing labs. This needs to be done w/in 3 weeks.

We are fielding requests from multiple testing labs who need scientists w/ the following qualifications:

1. At least a Masters or scheduled to graduate soon
2. Available IMMEDIATELY (in the next 1-3 weeks) for full-time paid work for temporary short-term contracts (at least 6 months, renewable, very likely to be renewed)

3. Live w/in commute distance of an #Ontario testing lab (throughout the province) or willing to quickly relocate

1/ Those who follow me know that I think too much and ask too many questions. In my curiosity, I recently stumbled upon a story of a bat cave of coronaviruses, sudden unexplained death, and mysterious poison mushrooms🍄 Buckle up it’s a weird one #medhistory #SARS #Covid_19 🧵👇
2/ It all started with that foolish preprint that was again claiming that SARS-CoV-2 was made in a lab. A claim that no respected scientist or clinician supports, given the lack of evidence, including: @K_G_Andersen @angierasmussen @CT_Bergstrom #COVID19

3/ So, I go back to what evidence we actually have. Because #science is awesome, we have a ridiculous amount of viral genomes that have continued to be tracked from early on in the pandemic:
- 4,678 @nextstrain @trevorbedford
- 84,932 @CovidGenomicsUK

As undergrad, I struggled immensely with this: reading and omg understanding papers.

Especially as non-native English speaker.

I did develop a system that helped me back then.

Bear with me it is pretty...mundane. 1/n

#reading #PhDLife #PDlife #undergradlife #papers #science
I printed each paper. And while reading I used a yellow, a green, and a pink highlighter.

When reading, I labeled every first mention of an abbreviation in green.

This helped me to find their meaning quickly again when deep into the text.

2/n
In pink, I labeled key questions and take-home messages.

If done correctly, you can look at pink sentences alone and recap the whole paper.

Peo-rip: first and last sentences of paragraphs often are pink sentences.

Pro-tip 2: write papers that have pink sentences.

yet, emotions aren’t facts..

they don’t exist beyond our experience of reality - they are a function of our existence ..

there exists only #OR - objective reality ..
e.g.
#love doesn’t exist beyond the function of survival of human offspring - - when the male stays with his children, he fends off potential male predators from killing them;
#empathy doesn’t exist beyond human kind, it is still very rare in the middle phase of human evolution;
the newest empathic neurotype believe that human predators such as Trump, Bolsonaro, Hitler etc are ‘evil’, yet predatory instincts evolved first in human species, driving predatory species like the Neanderthal for hundreds of millions of years — modern predators are a legacy..

Rife believed bacteria or viruses inside tumors emitted specific electromagnetic frequencies (EMFs). He developed a microscope that could detect EMFs from bacteria and viruses by the color of their auras.
- 🦠
In the 1930s, he developed a machine called the Rife Frequency Generator. Which produced low-energy radio waves with the same frequency as cancer-causing microbes. He believed sending this frequency to the body would make cancer-causing microbes shatter and die. This frequency
was called the mortal oscillatory rate.
- 🧬
It claimed the American Medical Association (AMA) and government agencies were covering up evidence about Rife machines.

Researchers have started experimenting with radiofrequency EMFs to treat cancer. They’ve concluded low-l

So let's unpack this.

We hear a lot about "#dashboards"; we were even promised sight of one, back in March* - though we've not seen it yet.

But what are they, in reality?

*healthtech.blog.gov.uk/2020/03/28/the… ImageImage
Well, for starters, we know quite a bit about @NHSEngland's 'dashboard(s)': back in March, @MattHancock gave it powers to DEMAND confidential patient information from care providers*, for (broadly defined) "#COVID19 purposes"...

Under the #COPInotices:

...and we know @NHSEngland's hoovering up *at least* 70 different datasets into its #DataStore (the list at data.england.nhs.uk/covid-19/ is no longer comprehensive due to the controversial contents of some of the datasets).

#Europe takes it, refurbishes, labels it their own.

🚨BREAKING: @HHSGov spokesman Michael Caputo and Dr. Paul Alexander tried to “browbeat” @CDCgov officials at the peak of the #pandemic—challenging the #science behind their public statements + attempting to silence CDC staff—to politically spin the data.
nytimes.com/2020/09/18/us/…
When Dr. Anne Schuchat, CDC principal deputy director, advised Americans to #WearAMask and warned, “We have way too much virus across the country,” Alexander—a part-time assistant professor of health research methods—wrote: “Her aim is to embarrass the president.”🙄

#COVID19
Alexander emailed Caputo, “She is duplicitous,” asking him to “remind” Schuchat that thousands of Americans died “under her work” during the 2009 H1N1 swine flu outbreak.

12,500 Americans died of swine flu in 1 year vs. >200,000 of #COVID19 in 6 months💥

🚨BREAKING: @CDCgov *reverses* its guidance on #coronavirus testing—it previously advised that asymptomatic people exposed to the virus “do not necessarily need a test,” but now clearly instructs: “You NEED a test.”

Prior guidance came from @HHSGov.🧐

nytimes.com/2020/09/18/wor…
‼️HSS officials bypassed CDC to post the prior DANGEROUS guidance advising NOT to test asymptomatic people exposed to #coronavirus—allowing undetected viral spread➡️MORE #COVID19 cases and deaths—just like last spring!

Trump is trying to spin the data🤬
CDC needs to continue stand for #science against Trump’s dangerous political antics to protect American lives.

This deadly #coronavirus does NOT care about politics. No matter how Trump spins it: the virus infects, spreads like wildfire, and kills.

Students in our universities are inundated with critical race theory. This is a marxist doctrine holding that America is a wicked and racist nation. That even young children are complicit in oppression, and that our society needs to be radically transformed.
2/
Critical race theory is being forced into our children’s schools, it’s being imposed into workplace trainings, and it's being deployed to rip apart friends, neighbours and families.
