JUST ONE PERSON—UK 🇬🇧 scientists think one immunocompromised person who cleared virus slowly & only partially wiped out an infection, leaving behind genetically-hardier viruses that rebound & learn how to survive better. That’s likely how #B117 started. 🧵 https://t.co/bMMjM8Hiuz

 2) The leading hypothesis is that the new variant evolved within just one person, chronically infected with the virus for so long it was able to evolve into a new, more infectious form.

same thing happened in Boston in another immunocompromised person that was sick for 155 days.
3) What happened in Boston with one 45 year old man who was highly infectious for 155 days straight before he died... is exactly what scientists think happened in Kent, England that gave rise to #B117. https://t.co/LBc8eCk3f9
4) Doctors were shocked to find virus has evolved many different forms inside of this one immunocompromised man. 20 new mutations in one virus, akin to the #B117. This is possibly how #B1351 in South Africa 🇿🇦 and #P1 in Brazil 🇧🇷 also evolved. https://t.co/74dr2pFiRg
5) “On its own, the appearance of a new variant in genomic databases doesn’t tell us much. “That’s just one genome amongst thousands every week. It wouldn’t necessarily stick out,” says Oliver Pybus, a professor of evolution and infectious disease at Oxford.
6) “New variants of Sars-CoV-2 are being created all the time but the vast majority of them go absolutely nowhere.
It was only when it became obvious that measures in Kent were failing that Public Health England realised the outbreak was being driven by a new variant.”
7) “#SARSCoV2 isn’t the only virus that can linger for an unusually long time within the human body. Ebola virus RNA has been detected in the semen of men a year after recovery. Some people stay infected with norovirus – a common stomach bug – for more than six months.
8) “One man in the UK has excreted infectious poliovirus for at least 28 years. The man had been shedding mutated virus for so long that researchers writing about his infection said that he, and other chronic excretors, pose an “obvious risk to the [polio] eradication programme”!
9) “But the real problem isn’t chronic infection – it’s a situation where pandemic is so out of control that the virus has endless opportunities to mutate into new variants. That situation is a reality in the UK and in dozens of other countries with dangerously high case rates.
10) ““These are all edge cases, but if you have enough people infected over a long time, you run the risk of hitting those edge cases,” says Hodcroft. It is not surprising that some of the most worrying new variants – from Brazil, South Africa and the UK –
11) ...”emerged from parts of the world with relatively high levels of transmission. “When you have millions of people infected, with millions of viruses replicating in each one, there are lots of chances for the virus to explore new mutations and combinations,” says Lauring.
12) ““If we had control of the virus, we wouldn’t be seeing as many variants pop up, because there wouldn't be as many opportunities for evolution to happen.”
13) Since Sars-CoV-2 infects cells relatively quickly, in most cases it enters a host, replicates and then swiftly infects someone else, leaving little time for the virus to acquire many genetic changes.
14) When the virus enters the body of someone who is already immunocompromised, their body is constantly applying evolutionary pressure on the virus – pushing it to evolve into new and, in some cases, more infectious forms.
15) My take: the moral lesson is that, when given time and opportunity, the virus finds a way. The virus is a cunning mutating beast that will try every way to defeat us if we let it keep proliferating. We must stop it FAST, or else it will evade: https://t.co/Zk46pouYLM
16) And the virus will even evade people who has had prior immunity and prior antibodies to the older common #SARSCoV2. Such as this example — here not even people were protected from severe disease even if with prior immunity. https://t.co/yqgeNJsgzj?
17) Now just look where we are... #B117 is threatening to dominate the US soon next month as well. Florida especially. https://t.co/I7zIjne6nD
18) It’s now growing so fast in Florida, #B117 is already at 10% of all cases. And doubling time in 9 days or maybe even less. https://t.co/DlHtxqaXAr
19) If we go for full suppression, then we can have this too https://t.co/6HkE2IoDTY

⚠️TWO DIFFERENT #COVID19 PANDEMICS—Many think with cases dropping that pandemic is nearly over. But truth is, there are now 2 different #SARSCoV2 pandemics diverging—old strain is waning, while the more contagious #B117 strain is dominating. We will be soon slammed very hard. 🧵


2) Here is what is really going to happen... most countries are having a gentle case decline with R(e) currently around 0.9. But this is deceiving. The #B117 is still relatively rare so far, so the R is being influenced mostly by the old common variant. But not for long...


3) Here is what is going to happen... currently R is ~0.9 in many places, but with the more infectious #B117, the R will jump 50% approximately. And it is inevitable (all CDC and Danish models say this) that B117 will take over as the reigning dominant variant soon...


4) and when that happens, what worked before to keep the pandemic contained at R of 0.9 will no longer work. Here is the model for Alberta, 🇨🇦 by @GosiaGasperoPhD. The B117 dotted red line will soon dominate and drive a new surge in latter half of March and April.


5) And Denmark 🇩🇰 CDC has found the same thing. I GQR works now for keeping R around 0.9 or even 0.8, will absolutely not work anymore once #B117 variant takes over. Forget about it. We will be hit hard. But there is a way—if we suppress R to 0.7 or less.

NEW—CDC was truly suffocated by Trump WH at every turn. Kyle McGowan, a former chief of staff at CDC, and his deputy, Amanda Campbell, witnessed WH dismissal of science, WH’s slow suffocation of CDC’s voice, meddling in messages & siphoning of CDC budget.
https://t.co/HeuNbUggiw


2) ““Everyone wants to describe the day that the light switch flipped—It didn’t happen that way—more of like a hand grasping something, and it slowly closes, closes, closes, closes until you realize that, middle of the summer, it has a complete grasp on everything at the CDC”

3) “Mr. McGowan and Ms. Campbell, both 34, say they tried to protect their colleagues against political meddling from WH and HHS but was largely stifled by the Trump administration.

4) “The White House insisted on reviewing — and often softening — the C.D.C.’s closely guarded coronavirus guidance documents, the most prominent public expression of its latest research and scientific consensus on the spread of the virus.”

5) “The documents were vetted not only by the White House’s coronavirus task force but by what felt to the agency’s employees like an endless loop of political appointees across Washington.
Mr. McGowan recalled a White House fixated on the economic implications of public health.

Stupid—Oregon church has huge 74+ person #COVID19 outbreak after dozens of maskless churchgoers stood onstage singing & clapping inside a packed indoor venue for Easter Sunday service. The Peoples Church, is vowing to do continue church service on Sunday.

2) Now, the Oregon Health Authority says that at least 74 people associated with the church have tested positive for the coronavirus — one of the state’s largest workplace outbreaks.

3) “In a statement, the church’s leaders attributed the outbreak to a recent rise in covid-19 cases in Marion County, Ore.

Murray said the church, which has held in-person services throughout the pandemic, intends to continue with in-person ceremonies on Sunday.

4) Who saw this coming? Countless scientists. If only airborne-denialists didn’t muzzle the airborne aerosols science.

Wow. 1 in 3 hospitalized with #COVID19 gets readmitted to the hospital within a few months after discharge. ~48,000 UK patients.

Great animated lecture on #LongCovid by @Dr2NisreenAlwan, animated by @VickiGSP using info from UK @IndependentSage experts.


2) Furthermore, 1 in 8 of those who were discharged subsequently die. And many suffer long term ailments like heart disease, liver, kidney, diabetes, and more. This doesn’t even include less clinical critical cognitive effects. #LongCovid is real.


3) How common is #LongCovid overall? UK estimates 1 in 5 at 5 weeks and 1 in 10 have symptoms have even 12 weeks after initial #COVID19 diagnosis.

Lecture again by @Dr2NisreenAlwan


4) Let these numbers sink in... 1 in 10 at 12 weeks still have symptoms!


5) Here is the original study of the above lecture from few weeks ago. We need to prepare our healthcare system long term for the impact of millions with #LongCovid. This is gonna be larger than Gulf War Syndrome or long term health of 9/11 first responders.

3) We cannot have a repeat of the fascism from WW2. This is @Schwarzenegger’s speech was so powerful.


4) My wife @andreafeigl1’s 🇦🇹 great grandfather secretly fought Hilter’s Nazi regime & smuggled many Jews to safety as an aircraft engineer. He was thrown into a concentration camp, and escaped.

She knows a few things about Nazi history—Jan 6th was downright fascist. Read 👇

Get a cup of coffee.

In this thread, I'll help you understand the basics of Binomial Thinking.

The future is always uncertain. There are many different ways it can unfold -- some more likely than others. Binomial thinking helps us embrace this view.


2/

The S&P 500 index is at ~3768 today.

Suppose we want to predict where it will be 10 years from now.

Historically, we know that this index has returned ~10% per year.

If we simply extrapolate this, we get an estimate of ~9773 for the index 10 years from now:


3/

What we just did is called a "point estimate" -- a prediction about the future that's a single number (9773).

But of course, we know the future is uncertain. It's impossible to predict it so precisely.

So, there's a sense of *false precision* in point estimates like this.

4/

To emphasize the uncertainty inherent in such predictions, a better approach is to predict a *range* of values rather than a single number.

For example, we may say the index will return somewhere in the *range* of 8% to 12% (instead of a fixed 10%) per year.

5/

10 years from now, this implies an index value in the *range* [8135, 11703]:

1) Science denial is destroying our societies, our civilization. Various vested interests, usually right wing ideologues find various scientific facts and information contrary to their agenda, so through propaganda they are orchestrating the public into denying this science.

2) We are seeing this with regard to the COVID virus, where a range of denial is being promoted, ranging from absolute denial the virus exists, to different levels of denial, such as only some people are vulnerable to the virus, to facilitate business as usual.

3) For a long time, to promote business as usual, vested interests have been promoting the denial of the climate and ecological crisis through propaganda. The aim being to create a large enough body of public denial to prevent action which can change anything.

4) We have seen similar patterns over a long time, such as when tobacco companies promoted denial of the emerging scientific evidence of how harmful and addictive tobacco smoking was. This further denial uses exactly the same methods.

5) Understandably, the public can't be educated about everything and have to rely on experts to inform them of concerns about threats to public safety. Malicious vested interests take advantage of this by using pseudo-experts to misinform the public.

Did we get dietary saturated fats all wrong? The #HADLmodel provides a new understanding and an opportunity to get it right. THREAD👇👇👇
@simondankel @kariannesve

Increased dietary saturated fatty acids lead to increased cholesterol in lipoproteins, but we don’t know why. Enter the #HADLmodel, which explains changes in lipoprotein cholesterol as adaptive homeostatic adjustments that ensure optimal cell membrane fluidity and cell function.

We propose that circulating lipoproteins enable appropriate redistribution of cholesterol molecules between specific cells and tissues, to accomodate changes in dietary fatty acid supply, due to our omnivore nature and variable intake of fatty acids. #HADLmodel

Our #HADLmodel implies that circulating levels of LDL change for protective, not for pathological reasons; an SFA-induced raise in LDL cholesterol in healthy individuals is a normal response, while a lack of this needed response may reflect a deeper pathology in lipid handling.

Circulating lipoproteins may change for pathological reasons, when regulatory mechanisms become disrupted by pathogenic processes related e.g. to inflammatory processes. Diverging lipoprotein responses in healthy versus metabolically unhealthy individuals support this view.

What is carbon capture? And how does it work?

While carbon capture is regularly discussed in the media, no one really ever explains what it is.

Below is a quick thread discussing the technology behind traditional carbon capture 👇

Carbon capture is broadly the "capture" of CO2 emissions from a power plant or other type of industrial facility.

Technology is connected to the "tailpipes" of these facilities and is used to remove CO2 from the plant exhaust.

Once the CO2 is removed from the plant exhaust, it is typically pressurized and sent under ground for permanent storage.

This step is called "sequestration" and is why experts often talks about "carbon capture and sequestration" or "CCS".

So how do you "capture" the CO2 molecules from exhaust?

Currently, one of the most economic forms of carbon capture is called "amine-based" capture.

An "amine" is a special liquid chemical which selectively grabs on to CO2 molecules.

To get the amine to grab on to the CO2, the amine is put into the top of a large column, while the exhaust is put into the bottom of the column.

The exhaust bubbles up through the column, and the amine drips down.

The liquid amine and gas exhaust mix in the column.

Look like that they got a classical case of PCR Cross-Contamination.
They had 2 fabricated samples (SRX9714436 and SRX9714921) on the same PCR run. Alongside with Lung07. They did not perform metagenomic sequencing on the “feces” and they did not get


A positive oral or anal swab from anywhere in their sampling. Feces came from anus and if these were positive the anal swabs must also be positive. Clearly it got there after the NA have been extracted and were from the very low-level degraded RNA which were mutagenized from

The Taq. https://t.co/yKXCgiT29w to see SRX9714921 and SRX9714436.
Human+Mouse in the positive SRA, human in both of them. Seeing human+mouse in identical proportions across 3 different sequencers (PRJNA573298, A22, SEX9714436) are pretty straight indication that the originals

Were already contaminated with Human and mouse from the very beginning, and that this contamination is due to dishonesty in the sample handling process which prescribe a spiking of samples in ACE2-HEK293T/A549, VERO E6 and Human lung xenograft mouse.

The “lineages” they claimed to have found aren’t mutational lineages at all—all the mutations they see on these sequences were unique to that specific sequence, and are the result of RNA degradation and from the Taq polymerase errors accumulated from the nested PCR process

RISHI PINGALA:THE ANCIENT INDIAN SAGE DISCREDITED FOR HIS MAJOR CONTRIBUTIONS TO MATHEMATICS & PHI

Have you ever heard about,"The Golden Ratio"?
The Golden Ratio or Phi(Greek) is a mathematical ratio of nature. Mother Nature is the most exquisite artist in herself.


&Its this Phi she uses to create all the beauty in World.
If anyone uses this ratio correctly in their art,it can turn into a spell-binding piece of work.Such is the significance of'Phi'.But my thread isn't about it.Its about somethin called'Fibonacci Series'&who actually made it


Phi is related to Fibonacci series(0,1,1,2,3,5,8,13,21,34...)
&this series is responsible for everything dat is beautiful on this planet. Just try to calculate the ratio of any 2 successive numbers ÷ each of them by the number before it in above infinite series.

E.g. 3/2=1.5, 5/3=1.666, 8/5=1.6, 34/21=1.61904 and so on. Did you notice something? The ratio is coming almost same every time. This ratio is called 'Phi 'which is numerically represented as 1:1.618. This Golden Spiral is made in exact proportion of 1:1.618.


The thing I want to emphasize here is that we always find only those things appealing and attractive that have Phi. It's in our subconscious. Isn't it some revelation? We are the part of this Divine proportion of the God or the Mother Nature. Check these:

Oleg Karpov pisze, że gdyby Siergiej Sirotkin zdobył w pierwszej części sezonu więcej punktów od Strolla, to jego kontrakt z automatu zostałby przedłużony na kolejny sezon. Tak się nie stało i Williams ma możliwość szukania innych opcji i to właśnie robi. #F1pl

Czego w artykule brakuje, to informacji, że SMP prawdopodobnie przekazało Williamsowi część środków na sfinansowanie sezonu 2019. W przypadku zakończenia współpracy ekipa z Grove będzie musiała zwrócić te środki. #F1pl

To tłumaczy wysokie kwoty jakich Williams ma oczekiwać za fotel od nowego kierowcy. Jest pewnie próg opłacalności i dopóki nie zostanie osiągnięty, to zmiana z finansowego punktu widzenia nie będzie się zwyczajnie opłacała. #F1pl
