MSN | K Rowling has challenged Scotland’s police to arrest her under the SNP’s new hate crime law after stating that a series of high-profile trans women are men.
The
Harry Potter author, who lives in Edinburgh, wrote on X, formerly
Twitter: “Freedom of speech and belief are at an end in Scotland if the
accurate description of biological sex is deemed criminal.
“I’m currently out of
the country, but if what I’ve written here qualifies as an offence under
the terms of the new Act, I look forward to being arrested when I
return to the birthplace of the Scottish Enlightenment.”
Rowling
posted pictures of 10 high-profile trans people on Twitter and mocked
their claims to be women. They included Isla Bryson, who was initially sent to a women’s prison after being convicted of two rapes.
al-mayadeen | Operation Al-Aqsa Flood has caught
"Israel" and the US by complete surprise. Americans are calling it
‘Israel’s Pearl Harbour’ moment --and an attack on America too). Nikki
Haley (running for election) is succinct: To Netanyahu: “Finish them”.
Al-Aqsa Flood is held to be "Israel’s"
greatest ‘intelligence failure’. Maybe so, but if Israeli and American
intelligence did not see the attack coming, it is because of their
Western mechanical, literal way of thinking. If I, and probably
thousands of Al Mayadeen readers, broadly knew that this was in the works (but not of course, of its operational details), why was "Israel" blind to it?
The writing was clearly written on the
wall. Two years ago, a missile campaign was unleashed from Gaza on "Tel
Aviv" in response to the Temple Mount Movement’s religious zealotry and
invasion of Al-Aqsa mosque.
Palestinians rallied to the call to
safeguard the Holy Mosque. It was not just Hamas; it was West Bank
Palestinians and (for the first time, too, 1948 Palestinians who have
Israeli passports) who all rose up to protect Al-Aqsa. Just to be clear,
the rallying cry was not for Hamas; it was not for Palestinian
nationalism. It was for Al-Aqsa -- an icon that goes to the heart of
what it is to be Muslim (Sunni or Shi’a). It was a cry that resonated
across the entire Islamic sphere.
Did the West not get it? Apparently
not. It was right under their nose, but super high-tech Intel doesn’t do
symbolic meaning. That was true for the 2006 Lebanon war too, by the
way; "Israel" could not grasp the symbolism of Hezballah’s ‘Karbala’
stand.
In the intervening period, "Israel" has
shattered into two equally weighted factions holding to two
irreconcilable visions of "Israel’s" future; two mutually opposing
readings of history and of what it means to be Jewish.
The fissure could not be more complete.
Except it is. One faction, which holds a majority in parliament, is
broadly Mizrahi -- a former underclass in Israeli society; and the
other, largely well-to-do liberal Ashkenazi.
So, what has this to do with Al-Aqsa
Flood? Well, the Right in Netanyahu’s government has two long-standing
commitments. One is to rebuild the (Jewish) Temple on ‘Temple Mount’
(Haram al-Shariff).
Just to be clear, that would entail demolishing Al-Aqsa.
The second overriding commitment is to
the founding of "Israel", on the "Land of Israel". And again, to be
clear, this (in their view) would entail clearing Palestinians from the
West Bank. Indeed, the settlers have been cleansing Palestinians from swaths of the West Bank over the past year (notably between Ramallah and Jehrico).
On Thursday morning (two days preceding
Al-Aqsa Flood), more than 800 settlers stormed the Mosque Compound,
under the full protection of Israeli forces. The drumbeat of such
provocations is rising.
This is nothing new. The First Intifada
was triggered by (then) PM Sharon making a provocative visit into the
mosque. I was a part of Senator George Mitchell’s Presidential Committee
investigating that incident. Even then, it was clear that Sharon
intended the visit to fuel the fire of Religious nationalism. At that
time, the Temple Mount Movement was a minnow; today it has ministers in
Cabinet and in key security positions -- and has promised its followers
to build the ‘Third Temple’.
So, the threat to Al-Aqsa has been
building for two decades, and today is reaching an apex. And yet US and
Israeli intelligence didn’t see resistance coming, and nor did they see
the settler violence building in the West Bank?
What happened on Saturday was widely expected and clearly extensively planned. So what’s next?
thesaker | The first Taliban press conference
after this weekend’s Saigon moment geopolitical earthquake, conducted
by spokesman Zabihullah Mujahid, was in itself a game-changer.
The contrast could not be starker with those rambling pressers at the
Taliban embassy in Islamabad after 9/11 and before the start of the
American bombing – proving this is an entirely new political animal.
Yet some things never change. English translations remain atrocious.
Here is a good summary of the key Taliban statements, and
– No problem for women to get education all the way to college, and
to continue to work. They just need to wear the hijab (like in Qatar or
Iran). No need to wear a burqa. The Taliban insists, “all women’s rights
will be guaranteed within the limits of Islamic law.”
– The Islamic Emirate “does not threaten anyone” and will not treat
anyone as enemies. Crucially, revenge – an essential plank of the
Pashtunwali code – will be abandoned, and that’s unprecedented. There
will be a general amnesty – including people who worked for the former
NATO-aligned system. Translators, for instance, won’t be harassed, and
don’t need to leave the country.
– Security of foreign embassies and international organizations “is a
priority.” Taliban special security forces will protect both those
leaving Afghanistan and those who remain.
– A strong inclusive Islamic government will be formed. “Inclusive” is code for the participation of women and Shi’ites.
– Foreign media will continue to work undisturbed. The Taliban
government will allow public criticism and debate. But “freedom of
speech in Afghanistan must be in line with Islamic values.”
– The Islamic Emirate of Taliban wants recognition from the
“international community” – code for NATO. The overwhelming majority of
Eurasia and the Global South will recognize it anyway. It’s essential to
note, for example, the closer integration of the expanding SCO – Iran
is about to become a full member, Afghanistan is an observer – with
ASEAN: the absolute majority of Asia will not shun the Taliban.
For the record, they also stated that the Taliban took all of
Afghanistan in only 11 days: that’s pretty accurate. They stressed “very
good relations with Pakistan, Russia and China.” Yet the Taliban don’t
have formal allies and are not part of any military-political bloc. They
definitely “won’t allow Afghanistan to become a safe haven for
international terrorists”. That’s code for ISIS/Daesh.
On the key issue of opium/heroin: the Taliban will ban their production. So, for all practical purposes, the CIA heroin rat line is dead.
As eyebrow raising as these statements may be, the Taliban did not
even get into detail on economic/infrastructure development deals – as
they will need a lot of new industries, new jobs and improved
Eurasian-wide trade relations. That will be announced later.
The go-to Russian guy
Sharp US observers are remarking, half in jest, that the Taliban in
only one sitting answered more real questions from US media than POTUS
since January.
What this first press conference reveals is how the Taliban are fast
absorbing essential P.R. and media lessons from Moscow and Beijing,
emphasizing ethnic harmony, the role of women, the role of diplomacy,
and deftly defusing in a single move all the hysteria raging across
NATOstan.
The next bombshell step in the P.R. wars will be to cut off the
lethal, evidence-free Taliban-9/11 connection; afterwards the “terrorist
organization” label will disappear, and the Taliban as a political
movement will be fully legitimized.
Moscow and Beijing are meticulously stage-managing the Taliban
reinsertion in regional and global geopolitics. This means that
ultimately the SCO is stage-managing the whole process, applying a
consensus reached after a series of ministerial and leaders meetings,
leading to a very important summit next month in Dushanbe.
WSJ | A genome is a blueprint for the factory of a cell to make proteins.
The language is made up of three-letter “words,” 64 in total, that
represent the 20 different amino acids. For example, there are six
different words for the amino acid arginine, the one that is often used
in supercharging viruses. Every cell has a different preference for
which word it likes to use most.
In the case of the gain-of-function supercharge, other
sequences could have been spliced into this same site. Instead of a
CGG-CGG (known as “double CGG”) that tells the protein factory to make
two arginine amino acids in a row, you’ll obtain equal lethality by
splicing any one of 35 of the other two-word combinations for double
arginine. If the insertion takes place naturally, say through
recombination, then one of those 35 other sequences is far more likely
to appear; CGG is rarely used in the class of coronaviruses that can
recombine with CoV-2.
In fact, in the entire class of coronaviruses that includes
CoV-2, the CGG-CGG combination has never been found naturally. That
means the common method of viruses picking up new skills, called
recombination, cannot operate here. A virus simply cannot pick up a
sequence from another virus if that sequence isn’t present in any other
virus.
Although the double CGG is suppressed naturally, the opposite
is true in laboratory work. The insertion sequence of choice is the
double CGG. That’s because it is readily available and convenient, and
scientists have a great deal of experience inserting it. An additional
advantage of the double CGG sequence compared with the other 35 possible
choices: It creates a useful beacon that permits the scientists to
track the insertion in the laboratory.
Now the damning fact. It was this exact sequence that appears
in CoV-2. Proponents of zoonotic origin must explain why the novel
coronavirus, when it mutated or recombined, happened to pick its least
favorite combination, the double CGG. Why did it replicate the choice
the lab’s gain-of-function researchers would have made?
Yes, it could have happened randomly, through mutations. But do
you believe that? At the minimum, this fact—that the coronavirus, with
all its random possibilities, took the rare and unnatural combination
used by human researchers—implies that the leading theory for the origin
of the coronavirus must be laboratory escape.
When the lab’s
Shi Zhengli
and colleagues published a paper in February 2020 with the virus’s
partial genome, they omitted any mention of the special sequence that
supercharges the virus or the rare double CGG section. Yet the
fingerprint is easily identified in the data that accompanied the paper.
Was it omitted in the hope that nobody would notice this evidence of
the gain-of-function origin?
NYMag | Take, for instance, this paper
from 1995: “High Recombination and Mutation Rates in Mouse Hepatitis
Viruses Suggest That Coronaviruses May Be Potentially Important Emerging
Viruses.” It was written by Dr. Ralph Baric and his bench scientist,
Boyd Yount, at the University of North Carolina. Baric, a gravelly
voiced former swim champion, described in this early paper how his lab
was able to train a coronavirus, MHV, which causes hepatitis in mice, to
jump species, so that it could reliably infect BHK (baby-hamster
kidney) cell cultures. They did it using serial passaging: repeatedly
dosing a mixed solution of mouse cells and hamster cells with
mouse-hepatitis virus, while each time decreasing the number of mouse
cells and upping the concentration of hamster cells. At first,
predictably, the mouse-hepatitis virus couldn’t do much with the hamster
cells, which were left almost free of infection, floating in their
world of fetal-calf serum. But by the end of the experiment, after
dozens of passages through cell cultures, the virus had mutated: It had
mastered the trick of parasitizing an unfamiliar rodent. A scourge of
mice was transformed into a scourge of hamsters. And there was more: “It
is clear that MHV can rapidly alter its species specificity and infect
rats and primates,” Baric said. “The resulting virus variants are
associated with demyelinating diseases in these alternative species.” (A
demyelinating disease is a disease that damages nerve sheaths.) With
steady prodding from laboratory science, along with some rhetorical
exaggeration, a lowly mouse ailment was morphed into an emergent threat
that might potentially cause nerve damage in primates. That is, nerve
damage in us.
"And we need to stop hunting for new exotic diseases in the wild, shipping them back to laboratories, and hot-wiring their genomes to prove how dangerous to human life they might become." https://t.co/N2Cnhk5Xde
A
few years later, in a further round of “interspecies transfer”
experimentation, Baric’s scientists introduced their mouse coronavirus
into flasks that held a suspension of African-green-monkey cells, human
cells, and pig-testicle cells. Then, in 2002, they announced something
even more impressive: They’d found a way to create a full-length
infectious clone of the entire mouse-hepatitis genome. Their “infectious
construct” replicated itself just like the real thing, they wrote.
Not
only that, but they’d figured out how to perform their assembly
seamlessly, without any signs of human handiwork. Nobody would know if
the virus had been fabricated in a laboratory or grown in nature. Baric
called this the “no-see’m method,” and he asserted that it had “broad
and largely unappreciated molecular biology applications.” The method
was named, he wrote, after a “very small biting insect that is
occasionally found on North Carolina beaches.”
In
2006, Baric, Yount, and two other scientists were granted a patent for
their invisible method of fabricating a full-length infectious clone
using the seamless, no-see’m method. But this time, it wasn’t a clone of
the mouse-hepatitis virus — it was a clone of the entire deadly human
SARS virus, the one that had emerged from Chinese bats, via civets, in
2002. The Baric Lab came to be known by some scientists as “the Wild
Wild West.” In 2007, Baric said that we had entered “the golden age of
coronavirus genetics.”
“I would be afraid to look in their freezers,” one virologist told me.
Baric
and Shi Zhengli of the Wuhan Institute of Virology, the two top experts
on the genetic interplay between bat and human coronaviruses, began
collaborating in 2015.
thebulletin | Why would anyone want to create a novel virus capable of causing a
pandemic? Ever since virologists gained the tools for manipulating a
virus’s genes, they have argued they could get ahead of a potential
pandemic by exploring how close a given animal virus might be to making
the jump to humans. And that justified lab experiments in enhancing the
ability of dangerous animal viruses to infect people, virologists
asserted.
With this rationale, they have recreated the 1918 flu virus, shown
how the almost extinct polio virus can be synthesized from its published
DNA sequence, and introduced a smallpox gene into a related virus.
These enhancements of viral capabilities are known blandly as
gain-of-function experiments. With coronaviruses, there was particular
interest in the spike proteins, which jut out all around the spherical
surface of the virus and pretty much determine which species of animal
it will target. In 2000 Dutch researchers, for instance, earned the
gratitude of rodents everywhere by genetically engineering the spike protein of a mouse coronavirus so that it would attack only cats.
Virologists started studying bat coronaviruses in earnest after these
turned out to be the source of both the SARS1 and MERS epidemics. In
particular, researchers wanted to understand what changes needed to
occur in a bat virus’s spike proteins before it could infect people.
Researchers at the Wuhan Institute of Virology, led by China’s
leading expert on bat viruses, Shi Zheng-li or “Bat Lady,” mounted
frequent expeditions to the bat-infested caves of Yunnan in southern
China and collected around a hundred different bat coronaviruses.
Shi then teamed up with Ralph S. Baric, an eminent coronavirus researcher at the University of North Carolina. Their work
focused on enhancing the ability of bat viruses to attack humans so as
to “examine the emergence potential (that is, the potential to infect
humans) of circulating bat CoVs [coronaviruses].” In pursuit of this
aim, in November 2015 they created a novel virus by taking the backbone
of the SARS1 virus and replacing its spike protein with one from a bat
virus (known as SHC014-CoV). This manufactured virus was able to infect
the cells of the human airway, at least when tested against a lab
culture of such cells.
The SHC014-CoV/SARS1 virus is known as a chimera because its genome
contains genetic material from two strains of virus. If the SARS2 virus
were to have been cooked up in Shi’s lab, then its direct prototype
would have been the SHC014-CoV/SARS1 chimera, the potential danger of
which concerned many observers and prompted intense discussion.
“If the virus escaped, nobody could predict the trajectory,” said Simon Wain-Hobson, a virologist at the Pasteur Institute in Paris.
Baric and Shi referred to the obvious risks in their paper but argued
they should be weighed against the benefit of foreshadowing future
spillovers. Scientific review panels, they wrote, “may deem similar
studies building chimeric viruses based on circulating strains too risky
to pursue.” Given various restrictions being placed on gain-of function
(GOF) research, matters had arrived in their view at “a crossroads of
GOF research concerns; the potential to prepare for and mitigate future
outbreaks must be weighed against the risk of creating more dangerous
pathogens. In developing policies moving forward, it is important to
consider the value of the data generated by these studies and whether
these types of chimeric virus studies warrant further investigation
versus the inherent risks involved.”
That statement was made in 2015. From the hindsight of 2021, one can
say that the value of gain-of-function studies in preventing the SARS2
epidemic was zero. The risk was catastrophic, if indeed the SARS2 virus
was generated in a gain-of-function experiment.
Seriously - Am I The Only Cat Fixated On This LOW HANGING SARS-CoV2 FRUIT?!?!?!
thescientist |Ralph Baric, an infectious-disease
researcher at the University of North Carolina at Chapel Hill, last week
(November 9) published a study on his team’s efforts to engineer a
virus with the surface protein of the SHC014 coronavirus, found in
horseshoe bats in China, and the backbone of one that causes human-like
severe acute respiratory syndrome (SARS) in mice. The hybrid virus could
infect human airway cells and caused disease in mice, according to the
team’s results, which were published in Nature Medicine.
The
results demonstrate the ability of the SHC014 surface protein to bind
and infect human cells, validating concerns that this virus—or other
coronaviruses found in bat species—may be capable of making the leap to
people without first evolving in an intermediate host, Nature reported. They also reignite a debate about whether that information justifies the risk of such work,
known as gain-of-function research. “If the [new] virus escaped, nobody
could predict the trajectory,” Simon Wain-Hobson, a virologist at the
Pasteur Institute in Paris, told Nature.
In October 2013, the US government put a stop to
all federal funding for gain-of-function studies, with particular
concern rising about influenza, SARS, and Middle East respiratory
syndrome (MERS). “NIH [National Institutes of Health] has funded such
studies because they help define the fundamental nature of
human-pathogen interactions, enable the assessment of the pandemic
potential of emerging infectious agents, and inform public health and
preparedness efforts,” NIH Director Francis Collins said in a statement at the time. “These studies, however, also entail biosafety and biosecurity risks, which need to be understood better.”
Baric’s
study on the SHC014-chimeric coronavirus began before the moratorium
was announced, and the NIH allowed it to proceed during a review
process, which eventually led to the conclusion that the work did not
fall under the new restrictions, Baric told Nature. But some researchers, like Wain-Hobson, disagree with that decision.
The
debate comes down to how informative the results are. “The only impact
of this work is the creation, in a lab, of a new, non-natural risk,”
Richard Ebright, a molecular biologist and biodefence expert at Rutgers
University, told Nature.
But Baric and others argued the
study’s importance. “[The results] move this virus from a candidate
emerging pathogen to a clear and present danger,” Peter Daszak,
president of the EcoHealth Alliance, which samples viruses from animals
and people in emerging-diseases hotspots across the globe, told Nature.
bloomberg | More than a year after Covid-19 touched off the worst pandemic in more than a century, scientists have yet to determine its origins.
The closest related viruses to SARS-CoV-2 were found in bats more than
1,000 miles from the central Chinese city of Wuhan, where the disease
erupted in late 2019. Initially, cases were tied to a fresh food market
and possibly the wildlife sold there. Other theories allege the virus accidentally escaped
from a nearby research laboratory, or entered China via imported frozen
food. Amid all the posturing and finger-pointing, governments and
scientists agree that deciphering the creation story is key to reducing
the risk of future pandemics.
1. Why don’t we know where it came from?
Where,
when and how a pathogen crosses the species barrier and begins
spreading in humans can be difficult, if not impossible, to pinpoint.
Although SARS-CoV-2 is genetically similar to coronaviruses collected
from a type of bat, it may have followed a long and convoluted path to
Wuhan, a city of 11 million people. Scientists are tracing the earliest
known cases to try to establish how they were infected, but the trail
backward largely goes cold in early December 2019. Where a new disease
starts spreading isn’t necessarily where it spilled over from the animal kingdom to infect the first human. HIV, for instance, is thought to have originated in chimpanzees in southeastern Cameroon, but didn’t begin spreading readily in people until the 1920s, when it reached the city of Kinshasa, hundreds of miles away. Scientists reported that finding in 2014, some three decades after the AIDS pandemic was recognized.
2. Who’s looking?
The World Health Organization was asked in May to help with the research, and a team of 17 international scientists, including one based in the U.S., concluded a four-week joint mission
with 17 researchers from China in early February. Their findings are
slated to be released in March. Other groups, including an expert panel convened by the medical journal The Lancet called the Covid-19 Commission, are also
3. What do we know so far?
Not much. Bats are the source of two coronaviruses that
caused lethal outbreaks in people during the past two decades -- severe
acute respiratory syndrome (SARS) and Middle Eastern respiratory
syndrome (MERS) -- and the flying mammals are considered the reservoir
host for SARS-CoV-2 as well as a plethora of other viruses. (A reservoir host is an animal that harbors a pathogen but isn’t sickened by it.) After SARS-CoV-2 emerged, Shi Zhengli, a virologist who heads a group that studies bat-borne coronaviruses at the Wuhan Institute of Virology, identified three closely related viruses collected during the previous 15 years. The closest, which is about 96% identical to SARS-CoV-2, was isolated from swabs and fecal material from Rhinolophus affinis, a species of horseshoe bat, in the southern Chinese province of Yunnan in 2013. Some researchers have linked that particular virus to a mineshaft in Mojiang county in Yunnan, where six men contracted a pneumonia-like disease
in 2012 that killed three of them. Although SARS-CoV-2 and the virus
from Yunnan may share a common ancestor, they’re not sufficiently similar
to indicate SARS-CoV-2 was derived from the Yunnan virus. Sampling of
bats in Hubei, the province of which Wuhan is the capital, haven’t found
any positive for the pandemic strain. Coronaviruses sharing certain
genetic features with SARS-CoV-2 have been found in other Rhinolophus
bat species and pangolins, a scaly, ant-eating mammal, elsewhere in Asia, highlighting the broad distribution
of related coronaviruses that may have contributed to SARS-CoV-2’s
evolution. That’s led to multiple hypotheses for how and where it
emerged.
counterpunch | Our proposal is consistent with all the
principal undisputed facts concerning SARS-CoV-2 and its origin. The MMP
proposal has the additional benefit of reconciling many observations
concerning SARS-CoV-2 that have proven difficult to reconcile with any
natural zoonotic hypothesis.
For instance, using different approaches,
numerous researchers have concluded that the SARS-CoV-2 spike protein
has a very high affinity for the human ACE2 receptor (Walls et al., 2020; Piplani et al., 2020; Shang and Ye et al., 2020; Wrapp et al., 2020).
Such exceptional affinities, ten to twenty times as great as that of
the original SARS virus, do not arise at random, making it very hard to
explain in any other way than for the virus to have been strongly
selected in the presence of a human ACE2 receptor (Piplani et al., 2020).
In addition to this, a recent report found that the spike of RaTG13 binds the human ACE2 receptor (Shang and Ye et al., 2020).
We proposed above that the virus in the mine directly infected humans
lung cells. The main determinant of cell infection and species
specificity of coronaviruses is initial receptor binding (Perlman and Netland, 2009).
Thus RaTG13, unlike most bat coronaviruses, probably can enter and
infect human cells, providing biological plausibility to the idea that
the miners became infected with a coronavirus resembling RaTG13.
Moreover, the receptor binding domain
(RBD) of SARS-CoV-2, which is the region of the spike that physically
contacts the human ACE2 receptor, has recently been crystallised to
reveal its spatial structure (Shang and Ye et al., 2020).
These authors found close structural similarities between the spikes of
SARS-CoV-2 and RaTG13 in how they bound the human ACE2 receptor:
“Second, as with SARS-CoV-2, bat RaTG13
RBM [a region of the RBD] contains a similar four-residue motif in the
ACE2 binding ridge, supporting the notion that SARS-CoV-2 may have evolved from RaTG13 or a RaTG13-related bat coronavirus
(Extended Data Table 3 and Extended Data Fig. 7). Third, the L486F,
Y493Q and D501N residue changes from RaTG13 to SARS CoV-2 enhance ACE2
recognition and may have facilitated the bat-to-human transmission of
SARS-CoV-2 (Extended Data Table 3 and Extended Data Fig. 7). A
lysine-to-asparagine mutation at the 479 position in the SARS-CoV-2 RBD
(corresponding to the 493 position in the SARS-CoV-2 RBD) enabled
SARS-CoV to infect humans. Fourth, Leu455 contributes favourably to ACE2
recognition, and it is conserved between RaTG13 and SARS CoV-2; its
presence in the SARS CoV-2 RBM may be important for the bat-to-human
transmission of SARS-CoV-2″ (Shang and Ye et al., 2020). (italics added)
The significance of this molecular
similarity is very great. Coronaviruses have evolved a diverse set of
molecular solutions to solve the problem of binding ACE2 (Perlman and Netland, 2009; Forni et al., 2017). The fact that RaTG13 and SARS CoV-2 share the same solution makes RaTG13 a highly likely direct ancestor of Sars-CoV-2.
A further widely noted feature of SARS-CoV-2 is its furin site (Coutard et al., 2020).
This site is absent from RaTG13 and other closely related
coronaviruses. The most closely related virus with such a site is the
highly lethal MERS (which broke out in 2012). Possession of a furin site
enables SARS-CoV-2 (like MERS) to infect lungs and many other body
tissues (such as the gastrointestinal tract and neurons), explaining
much of its lethality (Hoffman et al., 2020; Lamers et al., 2020).
However, no convincing explanation for how SARS-CoV-2 acquired this
site has yet been offered. Our suggestion is that it arose due to the
high selection pressure which existed in the miner’s lungs and which in
general worked to ensure that the virus became highly adapted to the
lungs. This explanation, which encompasses how SARS-CoV-2 came to target
lung tissues in general, is an important aspect of our proposal.
The implication is therefore that the
furin site was not acquired by recombination with another coronavirus
and simply represents convergent evolution (as suggested by Andersen et al., 2020).
An intriguing alternative possibility is
that SARS-CoV-2 acquired its furin site directly from the miner’s lungs.
Humans possess an epithelial sodium channel protein called ENaC-a whose
furin cleavage site is identical over eight amino acids to SARS-CoV-2 (Anand et al., 2020).
ENaC-a protein is present in the same airway epithelial and lung
tissues infected by SARS-CoV-2. It is known from plants that
positive-stranded RNA viruses recombine readily with host mRNAs (Greene and Allison, 1994; Greene and Allison, 1996; Lommel and Xiong, 1991; Borja et al., 2007).
The same evidence base is not available for positive-stranded animal
RNA viruses, (though see Gorbalenya, 1992) but if plant viruses are a
guide then acquisition of its furin site via recombination with the mRNA
which encodes ENaC-a by SARS-CoV-2 is a strong possibility.
A further feature of SARS-CoV-2 has been the very limited adaptive evolution of its genome since the pandemic began (Zhan et al., 2020; van Dorp et al., 2020; Starr et al., 2020).
It is a well-established principle that viruses that jump species
undergo accelerated evolutionary change in their new host (e.g. Baric et al., 1997). Thus, SARS and MERS (both coronaviruses) underwent rapid and readily detectable adaptation to their new human hosts (Forni et al., 2017; Dudas and Rambaut, 2016).
Such an adaptation period has not been observed for SARS-CoV-2 even
though it has now infected many more individuals than SARS or MERS did.
This has even led to suggestions that the SARS-CoV-2 virus had a period
of cryptic circulation in humans infections that predated the pandemic (Chaw et al., 2020).
The sole mutation consistently observed to accumulate across multiple
studies is a D614G substitution in the spike protein (e.g. Korber et al., 2020).
The numerically largest analysis of SARS-CoV-2 genomes, however, found
no evidence at all for adaptive evolution, even for D614G (van Dorp et al., 2020).
The general observation is therefore that
Sars-CoV-2 has remained functionally unchanged or virtually so (except
for inconsequential genetic changes) since the pandemic began. This is a
very important observation. It implies that SARS-CoV-2 is highly
adapted across its whole set of component proteins and not just at the
spike (Zhan et al., 2020). That is to say, its evolutionary leap to humans was completed before the 2019 pandemic began.
It is hard to imagine an explanation for this high adaptiveness other than some kind of passaging in a human body (Zhan et al., 2020). Not even passaging in human cells could have achieved such an outcome.
Two examples illustrate this point. In a follow up to Shang and Ye et al., (2020),
a similar group of Minnesota researchers identified a distinct strategy
by which the spike (S) protein (which contains the receptor bind
domain; RBD) of SARS-CoV-2 evades the human immune system (Shang and Wan et al., 2020).
This strategy involves more effective hiding of its RBD, but it implies
again that the spike and the RBD evolved in tandem and in the presence
of the human immune system (i.e. in a human body and not in tissue
culture).
The Andersen authors, in their critique of
a possible engineered origin for SARS-CoV-2, also stress the need for
passaging in whole humans:
“Finally, the generation of the predicted
O-linked glycans is also unlikely to have occurred during cell-culture
passage, as such features suggest the involvement of an immune system” (Andersen et al., 2020).
The final point that we would like to make
is that the principal zoonotic origin thesis is the one proposed by
Andersen et al. Apart from being poorly supported this thesis is very
complex. It requires two species jumps, at least two recombination
events between quite distantly related coronaviruses and the physical
transfer of a pangolin (having a coronavirus infection) from outside
China (Andersen et al., 2020).
Even then it provides no logical explanation of the adaptedness of
SARS-CoV-2 across its whole genome or why the virus emerged in Wuhan.
By contrast, our MMP proposal requires
only the one species jump, which is documented in the Master’s thesis.
Although we do not rule out a possible role for mixed infections in the
lungs of the miners, nor the possibility of recombination between
closely related variants in those lungs, nor the potential acquisition
of the furin site from a host mRNA, only mutation was needed to derive
SARS-CoV-2 from RaTG13. Hence our attention earlier to the figure from P. Zhou et al., 2020showing that RaTG13 is the most closely related virus to SARS-CoV-2 over its entire length. This extended similarity is perfectly consistent with a mutational origin of SARS-CoV-2 from RaTG13.
In short, the MMP theory is a plausible
and parsimonious explanation of all the key features of the COVID-19
pandemic and its origin. It accounts for the propensity of SARS-CoV-2
infections to target the lungs; the apparent preadapted nature of the
virus; and its transmission from bats in Yunnan to humans in Wuhan.
washingtontimes | Meanwhile, a number of suspicious actions and a paper trail suggest that the virus escaped from one of the labs, though China is clamping down on the ability to pursue those leads.
“The most logical place to investigate the virus origin has been
completely sealed off from outside inquiry by the CCP,” said the
document, referring to the Chinese Communist Party.
The party has taken draconian steps to control information about the virus since January.
“A gag order to both places was issued on Jan. 1, 2020, and a major general from the PLA who is China’s top military microbiologist essentially took over the [Wuhan Institute of Virology] since mid-January.”
Labs face scrutiny
Both of the labs under scrutiny in the report
have conducted extensive research on bat coronaviruses, including those
that have close molecular similarities to SARS-Cov-2, the full
designation of the new pathogen.
Among the most significant circumstantial
evidence identified in the report are the activities of Shi Zhengli, a
leader in bat coronavirus research with the Wuhan Institute of Virology,
China’s only high-security, level four research laboratory.
Ms. Shi has been involved in bioengineering bat
coronaviruses, and a medical doctor named Wu Xiaohua launched an online
campaign to expose Ms. Shi’s work. Dr. Wu said she believes the
coronavirus at the root of the pandemic is one of 50 viruses in a
database Ms. Shi manages.
The document also points to a 2015 academic report in Nature Medicine
by Ms. Shi and 14 other scientists who said that while researching the
potential for bat coronaviruses to infect humans, “we built a chimeric
virus encoding a novel, zoonotic [animal-origin] spike protein … that
was isolated from Chinese horseshoe bats.”
The scientists said the “hybrid virus” allowed researchers to study the ability of the virus to “cause disease.”
Dr. Wu stated in an internet posting that Ms.
Shi used laboratory animals to test the human-infecting virus, and one
of those animals may have been the origin of the pandemic.
Dr. Wu also asserted that the institute’s
virus-carrying animals had been sold as pets, dead laboratory animals
were not properly disposed of, and lab workers were known to boil and
eat laboratory-used eggs.
“Wu’s charges of WIV management negligence are specific and have not been convincingly rebutted by WIV,” the analysis said.
Ms. Shi has worked closely with several U.S.
virologists, and some American scientists have defended her and the
institute from critics who point to her work with bat viruses as a
needed focus of an investigation, the analysis says. Ms. Shi, in
response to Dr. Wu’s assertions, said in March on her social media
account: “I promise with my life that the virus has nothing to do with
the lab.”
newsweek | The NIH research consisted of two parts. The first part
began in 2014 and involved surveillance of bat coronaviruses, and had a
budget of $3.7 million. The program funded Shi Zheng-Li, a virologist
at the Wuhan lab, and other researchers to investigate and catalogue bat
coronaviruses in the wild. This part of the project was completed in
2019.
A second phase
of the project, beginning that year, included additional surveillance
work but also gain-of-function research for the purpose of understanding
how bat coronaviruses could mutate to attack humans. The project was
run by EcoHealth Alliance, a non-profit research group, under the
direction of President Peter Daszak, an expert on disease ecology. NIH
canceled the project just this past Friday, April 24th, Politico reported. Daszak did not immediately respond to Newsweek requests for comment.
The
project proposal states: "We will use S protein sequence data,
infectious clone technology, in vitro and in vivo infection experiments
and analysis of receptor binding to test the hypothesis that %
divergence thresholds in S protein sequences predict spillover
potential."
In layman's terms, "spillover potential" refers to the
ability of a virus to jump from animals to humans, which requires that
the virus be able to receptors in the cells of humans. SARS-CoV-2, for
instance, is adept at binding to the ACE2 receptor in human lungs and
other organs.
According to Richard Ebright, an infectious disease
expert at Rutgers University, the project description refers to
experiments that would enhance the ability of bat coronavirus to infect
human cells and laboratory animals using techniques of genetic
engineering. In the wake of the pandemic, that is a noteworthy detail.
Ebright,
along with many other scientists, has been a vocal opponent of
gain-of-function research because of the risk it presents of creating a
pandemic through accidental release from a lab.
Dr. Fauci is renowned for his work on the HIV/AIDS crisis in the
1990s. Born in Brooklyn, he graduated first in his class from Cornell
University Medical College in 1966. As head of NIAID since 1984, he has
served as an adviser to every U.S. president since Ronald Reagan.
A
decade ago, during a controversy over gain-of-function research on
bird-flu viruses, Dr. Fauci played an important role in promoting the
work. He argued that the research was worth the risk it entailed because
it enables scientists to make preparations, such as investigating
possible anti-viral medications, that could be useful if and when a
pandemic occurred.
The work in question was a type of
gain-of-function research that involved taking wild viruses and passing
them through live animals until they mutate into a form that could pose a
pandemic threat. Scientists used it to take a virus that was poorly
transmitted among humans and make it into one that was highly
transmissible—a hallmark of a pandemic virus. This work was done by
infecting a series of ferrets, allowing the virus to mutate until a
ferret that hadn't been deliberately infected contracted the disease.
WaPo | Two years before the novel coronavirus pandemic upended the world, U.S.
Embassy officials visited a Chinese research facility in the city of
Wuhan several times and sent two official warnings back to Washington
about inadequate safety at the lab, which was conducting risky studies
on coronaviruses from bats. The cables have fueled discussions inside
the U.S. government about whether this or another Wuhan lab was the
source of the virus — even though conclusive proof has yet to emerge.
In January 2018, the U.S. Embassy in Beijing took the unusual step of
repeatedly sending U.S. science diplomats to the Wuhan Institute of
Virology (WIV), which had in 2015 become China’s first laboratory to
achieve the highest level of international bioresearch safety (known as
BSL-4). WIV issued a news release in English about the last of these
visits, which occurred on March 27, 2018. The U.S. delegation was led by
Jamison Fouss, the consul general in Wuhan, and Rick Switzer, the
embassy’s counselor of environment, science, technology and health. Last
week, WIV erased that statement from its website, though it remains archived on the Internet.
What the U.S. officials learned during their visits concerned them so
much that they dispatched two diplomatic cables categorized as
Sensitive But Unclassified back to Washington. The cables warned about
safety and management weaknesses at the WIV lab and proposed more
attention and help. The first cable, which I obtained, also warns that
the lab’s work on bat coronaviruses and their potential human
transmission represented a risk of a new SARS-like pandemic.
“During
interactions with scientists at the WIV laboratory, they noted the new
lab has a serious shortage of appropriately trained technicians and
investigators needed to safely operate this high-containment
laboratory,” states the Jan. 19, 2018, cable, which was drafted by two
officials from the embassy’s environment, science and health sections
who met with the WIV scientists. (The State Department declined to
comment on this and other details of the story.)
The
Chinese researchers at WIV were receiving assistance from the Galveston
National Laboratory at the University of Texas Medical Branch and other
U.S. organizations, but the Chinese requested additional help. The
cables argued that the United States should give the Wuhan lab further
support, mainly because its research on bat coronaviruses was important
but also dangerous.
As the cable noted, the U.S. visitors met with Shi Zhengli, the head of
the research project, who had been publishing studies related to bat
coronaviruses for many years. In November 2017, just before the U.S. officials’ visit, Shi’s team had published research
showing that horseshoe bats they had collected from a cave in Yunnan
province were very likely from the same bat population that spawned the
SARS coronavirus in 2003.
harvardtothebighouse | we have Peter Daszak.
His company, EcoHealth Alliance, which is a non-profit that depends
largely on multi-million dollar government grants to function, has been partnering with Chinese researcher for years
in an attempt to secure funding for more and more research into
coronaviruses. At least they’re not really even pretending to be
philanthropic.
And in one of the more transparent attempts at blatant PR-spin, Daszak was featured alongside one of the researchers who learned how to create hyper-virulent bat coronaviruses
at UNC back in 2015, Zhengli Shi. Their article insists we should take
Zhengli at her word when she claims to have not found a match after she
checked COVID-19’s genome against everything in her lab. As if someone
responsible for releasing the most virulent pathogen to hit humanity in
modern history, one that’s already killed thousands and is projected to
kill millions and millions more all across the globe, would simply
fess-up to it, torpedoing her career and the years of research performed
by her and her colleagues? And possibly opening all of them up to legal
and other repercussions?
If you still aren’t sure whether the scientists involved with kind of
research are being forthright, there’s Dr. Ralph Baric. It was in his lab at UNC
that a hyper-virulent bat Franken-virus was created by splicing a new
protein-spike on an existing coronavirus, creating a monster so vicious
that a virologist with the Louis Pasteur Institute of Paris warned: “If the [new] virus escaped, nobody could predict the trajectory.” It
should also be noted that several years prior to tinkering directly
with bat coronavirus spike-proteins, Baric orchestrated research that
involved isolating a coronavirus from civets and then passing it through mammalian ACE2 receptor cells that
were grown in the lab from kidney and brain samples – serial passage
through host cell lines instead of entire hosts, which imparted a strong
affinity for ACE2, and presumably created an airborne strain of
coronavirus. And if cells derived from kidneys and brains were used for
the serial passage development of COVID-19, that might help explain its
affinity for attacking the kidneysand brains of its human hosts.
So if he was being honest, you might expect him to warn the public
about the lethal potential coronaviruses pose during our current
outbreak. However, when he was asked if the public should be worried
about COVID-19 he said that people should be more worried about the seasonal flu.
Pretty bizarre statement from a scientist who knew full well how
dangerous coronaviruses could be, especially given the fact that not only was Zhengli Shi working in his lab on that project in 2015, but Xing-Yi Ge was too. Both of whom returned to Wuhan where they’ve continued their work for years.
Xing-Yi Ge is especially notable since in 2013 he became the very first scientist to isolate a bat coronavirus from nature that uses the ACE2 receptor,
which is found in human, tree shrew, and ferret lungs and allows
coronaviruses to become airborne. And as you might have learned by now,
that’s the exact receptor used by COVID-19 to enter human cells – if
anyone would know how to finagle that part of the coronavirus genome,
it’d be him. So both Xing-Yi Ge and Zhengli Shi were part of the
research team that created this hybridized hyper-virulent bat
coronavirus under Baric, who’s actively downplayed the risk posed by
COVID-19, and then returned to work in Wuhan, where funding provided in
part by Daszak’s company allowed them to continue their work on
coronaviruses with plenty of research to cut-and-paste into their work
at the Wuhan Institute of Virology’s Disease Engineering Technical
Research Center.
And as Dr. Ian Malcolm puts it in Jurassic Park,
it is never a good idea to futz around with science and research when
you don’t fully understand it, nor its possible implications.
However it wasn’t just Daszak funding their work, Zhengli also
secured millions of dollars in grant money from various American
institutions including our Department of Defense as well as the U.S.
Biological Defense Research Directorate, and millions more from other
foreign governments.
So although the Chinese Communist Party deserves its share of the
blame for attempting to cover the outbreak up, arresting the heroic
scientists trying to warn us and issuing gag-orders and the destruction
of evidence, this research likely wouldn’t have occurred at all if the
NIH hadn’t lifted the ban on gain-of-function research in the first
place. And it was funded directly by American tax dollars, by government
officials willing to let others play god at their behest.
But now that the virus is out of the lab, are the private entities
responsible for its creation going to bear any of the blame at all? Or
will America and China continue to point fingers at each other until the
worst happens?
“Mars will accuse Earth of using a bio-weapon. Earth will claim
it was Mars. The Belt will blame the other two. It’s a good way to start
a war and cover it up.”
One last spoiler warning… okay, so in The Expanse the
central plot device pushing things forward is the discovery of a
mysterious substance dubbed the protomolecule, which seems to have a
mind of its own and seek out radiation as sustenance before then
beginning “the Work,” a mysterious intergalactic goal that isn’t
revealed until later seasons.
And its not individual nations who first attempt to harness the
protomolecule, but their Peter Daszak, the aforementioned scientist and
CEO named Jules-Pierre Mao, who attempts to weave it into the genomes of
immuno-compromised children to create hybridized super-soldiers. Not
for his own private army, but as a game-changing bio-weapon he’ll sell
to whichever government is willing to pay the most for it. So in The Expanse, it
takes amoral scientists as well as the collusion of officials
affiliated with both governments for this research to happen and be
hidden, and when these Hybrids are eventually dropped between both
armies the carnage is immense.
Luckily, we haven’t gotten that far on earth yet, but the rhetoric between America and China has been heading in that direction
– it’s been growing increasingly hostile as each blames the other for
starting the pandemic and covering it up, with China even going so far
as to threaten to cut off our supply of antibiotics and other
life-saving medical goods. Meanwhile Daszak, Baric, Zhengli, and others
sit back counting their lucky stars and their money, since both
governments and the public at large seem to have bought their story that
there’s no way this virus leaked out of one of their labs, and every
government on earth now wants to harness their research to help create
vaccines and treatments.
And these researchers have been assisted by scientifically spurious and journalistically vacuous articles which mindlessly regurgitate claims from the Chinese government, and its scientific propaganda arm,
the WHO, about how bad the outbreak was in the past and how contained
it is now. As the Chinese government arrested whistle-blowers and sent
agents out into the street in bio-hazard gear while carrying automatic
weapons to detain anyone suspected of breaking quarantine, while literally welding apartments buildings shut, the American media fawned over China’s “decisive and heroic” actions.
Please take a moment to consider the fact that almost everyone
reading the news to you on television was selected due to their
connections or how photogenic they are, not because of any actual
journalistic chops or ability to think critically.
So as two superpowers are pushed closer and closer to conflict, the
research that’s almost certainly the source of COVID-19 not only
continues unabated, but if anything talk of more funding to stop this
sort of supposedly natural pandemic from happening again is pouring into
the pockets of the people who, if they weren’t directly responsible,
should certainly have been at the forefront of warning the world about
the risks posed by lab-altered coronaviruses, and been disclosing the
existence of this sort of research in the first place.
Oddly, each and everyone one of them is pretending that viral
dual-use gain-of-function research has never occurred at all. Or not so
oddly, when you stop and think about how much they have to lose if their
role in this pandemic is revealed.
“The hardest part of this game is figuring out who the enemy really is.”
Other than the fact it doesn’t bear the direct marks of genetic
tampering, just like the engineered hyper-virulent H5N1 Bird Flu,
there’s literally nothing natural about COVID-19’s behavior or clinical
presentation. And hauntingly, peer-reviewed research has noted that a
crucial region of its genome “may provide a gain-of-function… for efficient spreading in the human population.”
Not only is it so distant from any other coronavirus that it forms
its own clade, but there isn’t even a natural path for it to have
emerged through – assertions about pangolins have always been dubious at
best, but were even further debunked when analysis of COVID-19’s genome
at the regions that most accurately show heritage made it “very unlikely” that pangolins had ever been involved at all.
Beyond that is the fact that its affinity for the ACE2 receptor is somewhere between 10 and 20 times higher than SARS, and it also creates viral loads thousands of times higher than SARS. These two characteristics point towards COVID-19 using antibody-dependent enhancement,
or ADE, to enter human cells. This is when the virus is able to hijack
white blood cells to more easily enter into the rest of our body’s
cells, allowing it to seep deep into its hosts’ nervous systems,
creating permanent neurological damage in the hosts it doesn’t kill
outright. ADE could also explain why between 5% and 10% of once “recovered” patients in Wuhan
have been showing up with fresh infections, since that phenomenon
allows a virus to hijack the antibodies created by a previous infection
to re-attack an old host. And curiously Zhengli Shi, of UNC and Wuhan
fame, co-authored a 2019 paper
which used inert viral shells to figure out exactly how SARS, with its
affinity to the ACE2 receptor just like COVID-19, was able to harness
ADE to hijack white blood cells for enhanced cell entry. A
gain-of-function extension of this research would be exactly the kind of
experiment that could’ve given birth to COVID-19, especially
considering that 2019 paper managed to fine-tune the exact concentration
of antibodies that would best facilitate ADE.
Both HIV and Dengue Fever use antibody-dependent enhancement to boost
their virulence, however its generally a phenomenon that takes a long
time to occur when it happens in nature. However COVID-19 looks like it may have had its ADE jacked into hyper-drive
as it was passed between a series of animal hosts, since it has the
aforementioned much stronger ability to bind to host cells and creates
viral loads orders of magnitude higher, and also appears to immediately
to be able to enter its hosts nervous systems, killing many of its
victims by attacking the region of the brain that controls breathing,
drastically lowering white blood cell counts early on in infections,
and apparently re-infecting individuals who had already appeared to
clear their infection.
Further increasing the possibility that COVID-19’s unique clinical
presentation may be due to its ADE being juiced by laboratory
engineering are the observations from an ER doctor who’s stated that I have seen things that I have never seen before…
I have witnessed medical phenomenon that just don’t make sense in the
context of treating a disease that is supposed to be viral pneumonia. In
an interview with Medscape, Dr. Cameron Kyle-Sidell went on to say that
the closest thing to the symptoms he was witnessing in his emergency
room.
WaPo | The story of how the novel coronavirus
emerged in Wuhan, China, has produced a nasty propaganda battle between
the United States and China. The two sides have traded some of the
sharpest charges made between two nations since the Soviet Union in 1985
falsely accused the CIA of manufacturing AIDS.
U.S.
intelligence officials don’t think the pandemic was caused by
deliberate wrongdoing. The outbreak that has now swept the world instead
began with a simpler story, albeit one with tragic consequences: The
prime suspect is “natural” transmission from bats to humans, perhaps
through unsanitary markets. But scientists don’t rule out that an
accident at a research laboratory in Wuhan might have spread a deadly
bat virus that had been collected for scientific study.
“Good science, bad safety” is how Sen. Tom Cotton (R-Ark.) put this theory in a Feb. 16 tweet.
He ranked such a breach (or natural transmission) as more likely than
two extreme possibilities: an accidental leak of an “engineered
bioweapon” or a “deliberate release.” Cotton’s earlier loose talk about
bioweapons set off a furor, back when he first raised it in late January
and called the outbreak “worse than Chernobyl.”
President Trump and Secretary of State Mike Pompeo added to the bile last month by describing the coronavirus as the “Chinese virus” and the “Wuhan virus,” respectively.
China
dished wild, irresponsible allegations of its own. On March 12, Chinese
foreign ministry spokesman Lijian Zhao charged in a tweet: “It might be [the] US army who brought the epidemic to Wuhan.” He retweeted an article that
claimed, without evidence, that U.S. troops might have spread the virus
when they attended the World Military Games in Wuhan in October 2019.
China retreated on March 22, when Ambassador to the United States Cui Tiankai told “Axios on HBO” that such rumors were “crazy” on both sides. A State Department spokesman said Cui’s comment was “welcome,”
and Trump and Chinese President Xi Jinping pledged in a March 27 phone
call to “focus on cooperative behavior,” a senior administration
official told me.
WashingtonTimes |Chinese government
researchers isolated more than 2,000 new viruses, including deadly bat
coronaviruses, and carried out scientific work on them just three miles
from a wild animal market identified as the epicenter of the COVID-19
pandemic.
Several Chinese state media outlets in recent months touted the virus research and lionized in particular a key researcher in Wuhan, Tian Junhua, as a leader in bat virus work.
The coronavirus strain now infecting hundreds
of thousands of people globally mutated from bats believed to have
infected animals and people at a wild animal market in Wuhan. The exact origin of the virus, however, remains a mystery.
Reports of the extensive Chinese research on bat viruses likely will
fuel more calls for Beijing to make public what it knows about such
work.
“This is one of the worst cover-ups in human
history, and now the world is facing a global pandemic,” Rep. Michael T.
McCaul, Texas Republican and ranking member of the House Foreign
Affairs Committee, said last week. Mr. McCaul has said China should be held accountable for the pandemic.
A video posted online in December and funded by the Chinese government shows Mr. Tian inside caves in Hubei province taking samples from captured bats and storing them in vials.
“I am not a doctor, but I work to cure and save people,” Mr. Tian says in the video. “I am not a soldier, but I work to safeguard an invisible national defense line.”
harvardtothebighouse | Some of the dystopian carnage creeping across China may be due to
the fact that much of China’s population may have already been exposed
to coronavirus infection via SARS or other less notorious strains, which
would allow the Wuhan Stain COVID-19 to use antibody-dependent enhancement to much more efficiently enter into cells,
and then become much more virulent since this enhancement hijacks the
body’s preexisting immune response to coronavirus infections and allows
easier entry. However whether or not people have been exposed to a
coronavirus infection before, once it’s been circulating in a population
for long enough the Wuhan Strain may be able to reinfect its own past
hosts and use this molecular hijacking on antibodies left from its own
previous infection to become far more virulent, regardless of whether or
not someone has been exposed to other coronaviruses before COVID-19.
And early reporting from Chinese doctors indicates that re-infections of the Wuhan Strain are far more lethal than the first.
– Additionally, although
another since-retracted pre-print noted several very short genomic
sequences in COVID-19’s spike-protein gene that look far more similar to
sequences found in HIV than to other coronaviruses – critics
quickly pointed out that the shared homology didn’t reach statistical
significance. However a closer look at the data reveals that there were a
few small shared genomic segments that, despite being physically
separated from each other along each strand of DNA, all worked together
to code for the Wuhan Strain’s protein-spike’s crucial receptor binding
site. Something that is highly unlikely to have happened by chance. And
despite most of its protein-spike being shared with SARS, these
substituted segments weren’t shared at all – nor were they found in any
other coronavirus. One possible but likely reason for these HIV-like
segments is that they were meant to be epitopes, or molecular
flags meant to mark intruders for a vaccine to target. It is
mathematically possible for this to happen in nature – but only in a ten-thousand bats chained to ten-thousand Petri dishes and given until infinity sense. Alternatively, it could also be produced by infecting a room full of ferrets with a bespoke coronavirus vaccine and sifting through the wreckage for your genomic needle.
– Even more troubling, a peer-reviewed study noted that one
particular part of the Wuhan Strain’s spike-protein genome also wasn’t
found in any of its relatives, “and may provide a gain-of-function to [COVID-19] for efficient spreading in the human population.”
And according to that paper, this particular type of furin cleavage
site makes similar viruses both more pathogenic and more neurotoxic.
– Evidence for the Wuhan Strain’s neurotoxicity arrived in late February, in a published paper which notes that “the
most characteristic symptom of COVID‐19 patients is respiratory
distress, and most of the patients admitted to the intensive care could
not breathe spontaneously.” Combined with the observation that “some
COVID‐19 patients also showed neurologic signs such as headache, nausea
and vomiting,” this paper asserts that since SARS was found heavily
concentrated in the brainstems of its autopsied victims, COVID-19 is
also probably crossing the blood-brain barrier and killing its victims
not just via pneumonia, but also by causing neurological respiratory
failure.
– One of the worst possible scenarios for COVID-19’s mutation rate would be if it falls into the Goldilocks range that would allow it to form mutant viral swarms:
too many mutations will cause a virus to eventually implode, not enough
allows host immune systems to catch-up, but if things are just right
mutant swarms can form and spread across host populations, burrowing
into host nervous systems and causing permanent neurological damage.
Mutant swarms form when a virus produces mutationally-damaged copies of
itself inside a host, some of which aren’t infectious but find their way
into the nervous system where they burrow in causing damage, and others
that combine with complimentary broken copies inside host cells to
produce working infectious copies of the virus. So a host can not only
become crippled with neurological issues, but also still be producing
infectious copies of the virus. And it seems as if COVID-19 has many
characteristics that indicate the potential to form mutant swarms: the
“striking” mutation rate mentioned above and the fact a second
widespread mutated strain seems to have already emerged in Washington
State with many other isolated strains reported elsewhere, crossing
between species is another factor and a dog in Hong Kong appears to have
tested positive, the fact that the Wuhan Strain can infect not only the
respiratory tract but feces as well – multi-organ involvement is an important contributor to viral swarms,
and finally the markedly viral load rate of COVID-19 compared to SARS –
SARS produced a viral load several times lower which decreased over
time, while COVID-19 produces a “very high” viral load that appears to increase over time and can peak several orders of magnitude higher than SARS was measured to reach. And alarming evidence that this phenomenon is occurring emerged from a Chinese pre-print which noted that over one-third of the roughly 200 patients studied has some neurological symptoms, with nearly half of the most severe patients exhibiting neurological issues.
– Another exceptional trait of the Wuhan Strain COVID-19 is that not
only does it form its own clade, it’s calculated to have diverged from
SARS and its other sister coronaviruses some 260 years ago. And yet in all that time, while it every other branch of the coronavirus tree was busy branching-off into countless variants,
if it emerged naturally, COVID-19 somehow spent a quarter of a
millennium as the lone known example of its clade, somehow not mutating
into related lineages in all that time. Another simpler explanation is
that this apparent hereditary distance and genetic uniqueness is the
just the result of being altered in a lab. And although two distinct
strains of COVID-19 have been identified, there’s no reason to believe
this mutational differentiation happened before contact with humans in
December of 2019. Additionally, when neutral sites, the specific points
in the genome which most reliably show evolutionary change, were
examined: COVID-19 looks even more evolutionarily distant from any of its possible relatives.
