June 29, 2021 (LifeSiteNews) — Researchers from two Australian universities have published a paper demonstrating that COVID-19 is especially adept at infecting human cells and not those of bats, furthering speculation over the pathogen’s origin.
A team of scientists from Flinders University in South Australia, along with researchers at La Trobe University, Victoria, published a study June 24 on the ability of the molecule associated with SARS-CoV-2 infection, the spike protein, to bind with ACE2 (angiotensin converting enzyme 2) proteins in a range of animal species. The team designed their study to focus on the most receptive species to COVID-19 infection with the hope that more might be known about cross-species transfer of the virus from an intermediary animal vector, as was proposed in the previously favored bat-origin thesis.
However, the researchers discovered that, in line with the lab-leak thesis, “[s]pike protein exhibited the highest binding to human (h)ACE2 of all the species tested,” including bats and a further eleven domestic and wild animal species, which means that the spike protein is more suited to attacking human cells than any other proposed origin species, they said. Typically, it is expected that the highest binding capacity of a viral protein to the cells of a particular species shows that species to be the most likely origin of the virus.
“[C]omputer modelling found the virus’s ability to bind to the bat ACE2 protein was poor relative to its ability to bind human cells. This argues against the virus being transmitted directly from bats to humans,” said Professor Nikolai Petrovsky, epidemiologist at Flinders University. As a result, “if the virus has a natural source, it could only have come to humans via an intermediary species which has yet to be found.”
David A. Winkler, biochemistry and genetics professor at La Trobe University, also on the research team, noted surprise that human ACE2 cells “showed the strongest spike binding,” especially if “an animal was the initial source of the infection in humans.” Winkler explained that pangolins, an anteater found in parts of Africa and southeast Asia, showed the highest binding strength of all the non-human animals tested, returning results markedly higher than bats but still less than humans.
Despite having the highest susceptibility of non-human animals, the researchers stressed that “nevertheless, no SARS-CoV-2-like virus has been found in pangolins, suggesting they were not the original source.” Petrovsky added that, “putting aside the intriguing pangolin ACE2 results, our study showed that the COVID-19 virus was very well adapted to infect humans.”
“Based on available genome sequence data, this study concluded that the current pandemic has been driven entirely by human-to-human transmission since at least December,” the researchers wrote.
“In summary, our study suggests that from the beginning of this pandemic the SARS-CoV-2 S [spike] protein already had very high, optimal binding to [human] hACE2. There is minimal early evidence of selection pressure to further optimise binding, in contrast to what has been seen with other zoonotic [cross-species] viruses at the time of their entry into the human population.”
In the meantime, support grows for the Wuhan lab-leak theory, whereby gain-of-function research on coronaviruses at the Wuhan Institute of Virology led to the first known instances of COVID-19 infections in the city of Wuhan, despite an initial pushback on the hypothesis from Big Tech and members of the scientific community, such as Dr. Anthony Fauci.
Fauci, who acts as the chief medical adviser to the president, was found to have sent funds through his National Institute of Allergy and Infectious Diseases (NIAID) toward virus enhancement research at the Wuhan Institute of Virology. Fauci, as head of the NIAID, had authorized the funding to a group called the EcoHealth Alliance for five years, between 2014 and 2019. The group’s head, Dr. Peter Daszak, used the money to contract with Dr. Shi Zheng-li, a virologist in Wuhan, on gain-of-function experimentation.
PETITION UPDATE (5/12/2021) -
It seems that Dr. Anthony Fauci's role in the NIH's funding of so-called "gain-of-function" research may be catching up with him.
In the last couple of days, both U.S. Senator Rand Paul and Fox's Tucker Carlson have laid into Fauci for his alleged promotion of this dangerous research which develops bat-based coronaviruses into more potent variants, capable of infecting humans.
Dr. Fauci denied funding this research.
But, Senator Paul noted that a resident virologist at the Wuhan Institute of Virology, Dr. Shi Zheng-li and Dr. Ralph Baric, an American virologist funded by Fauci's department in the NIH, "collaborated on gain-of-function research where they enhanced the SARS virus to infect human airway cells and they did it by merging a new spy protein on it. That is gain-of-function. That was joint research between the Wuhan Institute and Dr. Baric. You [Dr. Fauci] can’t deny it."
And, later, Fox News host Tucker Carlson picked up on the discrepancy, noting Fauci’s involvement in the creation and promotion of public health directives on account of COVID-19 while also being allegedly tied to the origin of the virus and its spread throughout the world.
So, the evidence - both in testimony and in the court of public opinion - continues to mount.
Could we ask you to consider SIGNING and SHARING this important petition, which calls for Dr. Fauci to be fired and investigated for any role he played in promoting and funding the dangerous research which may have cost the world dearly in lives and jobs lost.
When concerned scientists warned the US government of the great danger of creating superviruses in the lab, one man publicly defended the risky experiments: that man was the influential head of the National Institute of Allergy and Infectious Diseases (NIAID), none other than "Mr. Science" himself: Dr. Anthony Fauci.
In 2014, the same year the US government called for a moratorium on this insanely dangerous research, Dr. Fauci's NIAID began funding a program to study the transmission of bat coronaviruses to humans.
Not only did his funding go to develop the technology for making bat coronaviruses spread more easily to humans, but much of it went to the lab located in the exact location where the Covid pandemic eventually emerged: Wuhan, China.
Like every person, Dr. Fauci deserves to be presumed innocent until proven guilty.
But the evidence is so overwhelming that Fauci gambled with a supervirus and lost (the whole world lost), that, at a minimum, he needs to be fired from his position of public trust and must be investigated for possible violations of US law which mandated a moratorium on this extremely dangerous practice of creating superviruses in the lab.
However Dr. Fauci, far from being held responsible for his dangerous gamble, has been promoted to the point where, currently, he is the highest paid employee in the US Government.
Please SIGN and SHARE this petition if you agree that Dr. Anthony Fauci should instead be immediately fired and investigated for his role in causing the Covid-19 pandemic.
Just like the Wall Street moguls, whose financial negligence precipitated the financial crisis of 2008, received massive bailout bonuses, Dr. Anthony Fauci recklessly pushed for the research that probably caused the deadly pandemic. And now, he, too, has been rewarded with money and power.
As has been carefully and meticulously documented by Steve Hilton of Fox News, the probable origins of the coronavirus point to Dr. Anthony Fauci.
Dr. Fauci was one of the greatest proponents of developing superviruses in labs.
Dr. Fauci was responsible for the funding of much of the research through the NIAID.
And, it appears that Dr. Fauci funneled taxpayer funds through an intermediary to allow the research to continue in the unsafe Wuhan Institute of Virology, even after the US government banned the funding of this dangerous research.
Until a thorough investigation into his role of the origins of the current pandemic has taken place, Dr. Fauci should not be in a position of public trust.
Please SIGN and SHARE this petition to demand that Dr. Fauci be fired immediately and investigated fully for his role in the creation of Covid-19 and the ensuing pandemic.
P.S. It should be noted that Dr. Fauci not only has proven to be catastrophic for public health with his advocacy of dangerous research, but he has also been a disastrous public health advisor, advocating measures that have negatively impacted every aspect of our lives, from the economy to our most fundamental liberties.
P.P.S. Dr. Anthony Fauci, recently stated that he is delighted to be pushing Joe Biden's return to US taxpayer funding of abortions abroad. So, evidently, not only does Dr. Fauci have problems with public health, public safety, and economics, but also with basic human rights and embryology.

After the coronavirus outbreak started to make headlines, Daszak organized a letter, published in The Lancet in February 2020, categorically dismissing “conspiracy theories suggesting that COVID-19 does not have a natural origin.” In January 2021, however, a spokesman for Daszak said that the British scientist had penned the letter to protect Chinese scientists who were receiving death threats at the time.
Daszak was invited to be part of a World Health Organization (WHO) team investigating the origins of the virus that same month, acting as their sole American representative. The report returned an “extremely unlikely” verdict on the virus originating in the laboratory.
Following reports among mainstream media outlets like the Wall Street Journal giving credence to the lab-leak theory, Big Tech drastically changed its position on censorship of those who would give a platform to the thesis. Social media giant Facebook revised its “misinformation” policy to no longer include the Wuhan lab-leak in its intent to “remove false claims on Facebook and Instagram about COVID-19,” namely that “COVID-19 is man-made or manufactured,” which they said was “debunked by public health experts” at the time.
