Discussion: Chinese Academy of Sciences (CAS) in Wuhan has been working with bats and coronavirus for many years - DNA manipulations, cloning.... - Ja

That is a very good interview. I've looked at more of Weinstein's channel and found it really interesting. He and his wife were professors at Evergreen State in Olympia, WA, about an hour from where I live. We truly are living in a world where it is getting more dangerous to tell the truth.
 
Thanks, Shiloh. He thinks like a chemist which is to say he actually thinks. I have someone in the family with a chemistry and medical lab background. He's been convinced that SARS-2 was a lab escape from the beginning.

"“The difference between our approach and other vaccine manufacturers is that we have a chemistry background, and we analyse the virus in detail as if we were making a drug,” S?rensen starts to explain."
 
MSCOX - PCR does not need live virus or even a whole strand, if you give it a whole strand it will break it into bits anyway. These short sections are then compared to the probes you have selected to test the sample against (this will be a short sequence, 20NTs typically, of SARS 30,000 NT genome) and then makes a DNA equivalent of any matches. A fluorescent marker is normally added to the nucleotides in the solution and are incorporated into this new DNA. The solution is then thermo-cycled (which basically doubles the DNA) repeatedly until there is enough DNA fluorescing to be detected. If there is any RNA present that matches the probe you will eventually get a glow the question is how many doublings does it take to get to that point. If it comes back positive after 10 to 20 cycles, this would be a strong positive from a clinical sample, if you get to 35 cycles without detection then it is deemed a fail, these numbers are typical but you can pick your sensitivity threshold. The sample you start with could be from a single infected patient or from bat guano (with a mix of viral, bat, bacterial and other RNAs) in either case the PCR is going to look for matches to your probe which is selected from a region you think/hope is unique to the virus you are interested in. The CDC uses 3 probes in its assay all short sections from the N gene.

Emily – In the link I provided Daszak states that it was a consensus sequence. In the whole interview and an earlier one, from Dec. 2019 pre outbreak, he explains clearly how they go about collecting the samples. SL betaCoVs are endemic in the bat population but circulate at fairly low level so only a few percent would be PCR positive at any time and 30% would be seropositive, much like avian flu strains in wild bird populations. Micro-bats are very difficult to sample in volume so PCR of guano is the normal method of finding out what viruses are prevalent in the population. The BSL4 lab in Wuhan has 4 live strains that they are culturing none of them are RaTG13. All this work was done prior to SAR-2 and mainly to look for the origin of SARS-1 and to find other SL sequences that are close to the Zoonotic edge and are therefore ripe to make the species jump to humans.

Kathy – You seem determined to see nefarious actions on the part of Shi et. al. when I would argue that all of what has happened is typical zoonotic behaviour we have seen played out hundreds of times in animal to human spill overs and requires no other mechanism. A Furin cleavage site has been found in other samples and all of reading frames that occur in SARS, 1 or 2, can be found in bats if we look, but then the funding to look has been cut so if you want the truth try and get the funding re-established.
 
JJackson: I never accused Shi. Any lab having the right sequence might have synthetized RaTG13 and manipulated it. The furin cleavage site is not natural in this group of viruses as I wrote it already several times and I won't repeat it. The RmYN02 strain has been claimed to have a kind of insertion but the alignment is false and there is actually no insertion, just mutations with no function in cleavage. This is an example of fabricated evidence for the natural origin for SARS-CoV-2.

You can see the false alignment here:

I am not aware of the hundreds of natural spill-over as SARS-CoV-2. This time there were no intermediate jumps and adaptation from animals as in the first SARS and in MERS. SARS-CoV-2 was from the beginning perfectly adapted to hACE2:

“SARS-CoV-2 is well adapted for humans. What does this mean for re-emergence?”

COVID-19: COVID: Eight questions for the WHO team going to China next week to investigate pandemic origins

BY GUEST WRITER ON JUNE 30, 2020.
By Daniel R. Lucey M.D., MPH, FIDSA
...
1. What animals in the Wuhan Huanan Seafood Market were tested, what types of specimens were obtained, and what were all the results?

2. What does a “One Health” (human, animal, environmental) blueprint map of the market show...

3. What exactly were each of the 33 virus-positive environmental samples (e.g., what type of sewage, cutting boards, door handles, garbage truck)?
...
4. What are the detailed results of testing in other markets in Wuhan, outside Wuhan in Hubei province, and outside Hubei province?
...
5. What are the complete data referenced in the March 13, 2020 article in the South China Morning Post (by Josephine Ma) titled: “Coronavirus: China’s first confirmed Covid-19 case traced back to November 17.”
...
6. Given that the origin of the virus has been stated by the China CDC Director not to be the Wuhan Huanan Seafood Market (as quoted in the May 23 SCMP (by Zhuang Pinghui) was quoted in the South China Morning Post May 23 saying: it is important to address questions about any potential laboratory source of the virus, whether in Wuhan or elsewhere e.g. What kind, if any, “Gain-of-Function” experiments were done with coronaviruses...

7. Were any type of laboratory ferret-to-ferret passage of coronaviruses performed whether in Wuhan or elsewhere in China, or in collaboration with foreign laboratories? If so, what viruses were studied and what were the results? Were coronaviruses studied in any ferret-to-ferret studies that came from different animal e.g., bats, pangolins, and/or other animals?

8. Why was the single specific environmental virus isolate from the Wuhan Huanan Seafood Market used chosen, as well as the single specific human isolate of the virus chosen in the experiments to infect ferrets in the “in the biosafety level 4 and animal biosafety level 4 facilities in the Harbin Veterinary Research Institute (HVRI) of the Chinese Academy of Agricultural Sciences (CAAS)”?

Structural analysis of COVID-19 spike protein provides insight into its evolution

9-Jul-2020 12:45 PM EDT, by Francis Crick Institute

Newswise — Researchers at the Francis Crick Institute have characterised the structure of the SARS-CoV-2 spike protein as well as its most similar relative in a bat coronavirus. The structures provide clues about how the spike evolved and could help inform vaccine design.

A characterising feature of SARS-CoV-2, the virus that causes COVID-19, is the protein spikes which cover the surface, which the virus uses to bind with and enter human cells.

Analysing the structure of these spikes could provide clues about the virus' evolution. It is not yet known how SARS-CoV-2 evolved to infect humans and whether this happened directly from coronaviruses in bats or via an intermediary species.

In their study, published in Nature Structural & Molecular Biology, the researchers characterised the spike protein in high resolution using a technique called cryo-electron microscopy, which allowed them to achieve a greater level of detail than previously reported structures. They then compared this structure to the spike protein of a bat coronavirus, RaTG13, which has the most similar spike to that of SARS-CoV-2.

While the spikes as a whole were over 97% similar, the researchers found a number of significant differences at the location where SARS-CoV-2 binds with a receptor on human cells, called ACE2, and at the surfaces that keep the subunits of the spike together.

These differences mean the spike of SARS-CoV-2 is more stable and is able to bind around 1,000 times more tightly to a human cell than this bat virus.

Based on their findings, the researchers suggest it is unlikely that a bat virus similar to RaTG13 could infect human cells. This supports the theory that SARS-CoV-2 is the result of different coronaviruses coming together and evolving over time, potentially also through several host species.

Antoni Wrobel, co-lead author and postdoctoral training fellow in the Structural Biology of Disease Processes Laboratory at the Crick, says: "The spike is the entry key that allows SARS-CoV-2 into human cells. Changes in the virus' genome, which affect the spike's structure, therefore have potential to make the virus either more or less able to enter the host's cell."

"At some point in the evolution of this virus, it seems to have picked up changes, like the differences we found, which made it able to infect humans."

Donald Benton, co-lead author and postdoctoral training fellow in the Structural Biology of Disease Processes Laboratory at the Crick, says: "The exact process of how SARS-CoV-2 evolved remains unclear and is something many researchers are trying to piece together. Our work provides a piece of this puzzle, as it suggests that the virus did not come straight from the bat coronaviruses currently known."

Steve Gamblin, group leader of the Structural Biology of Disease Processes Laboratory at the Crick says: "The world was caught off guard by SARS-CoV-2. Examining the structure of this virus, and its likely precursor, helps us understand where it came from, and how it interacts with human cells."

The Crick researchers will continue to study the structure of the virus, with a view to finding further clues as to its evolutionary path.

The spike protein structures are open-access, so other researchers can use these in their work and to aid with drug discovery and vaccine design.

EXCLUSIVE: Chinese virologist accuses Beijing of coronavirus cover-up, flees Hong Kong: 'I know how they treat whistleblowers'

Li-Meng Yan told Fox News that she believes China knew about the coronavirus well before it claimed it did. She says her supervisors also ignored research she was doing that she believes could have saved lives.

She also claims the co-director of a WHO-affiliated lab, Professor Malik Peiris, knew but didn't do anything about it.

Peiris also did not respond to requests for comment. The WHO website lists Peiris as an "adviser" on the WHO International Health Regulations Emergency Committee for Pneumonia due to the Novel Coronavirus 2019-nCoV.

Yan was frustrated, but not surprised.

"I already know that would happen because I know the corruption among this kind of international organization like the WHO to China government, and to China Communist Party," she said. "So basically... I accept it but I don't want this misleading information to spread to the world."

Many thanks Professor Peiris!

On Friday 3 July, all staff of the HKU-Pasteur Research Pole gathered for a very special happy hour to express their heartfelt and sincere thanks to Professor Malik Peiris, who is stepping down as Co-Director of HKU-Pasteur.

Malik Peiris co-directed the HKU-Pasteur Research Pole for 14 years alongside Professor Roberto Bruzzone, who welcome Malik by briefly remembering how his work has been significant to HKU-Pasteur and to science as a whole.

In the presence of Professor Keiji Fukuda, Director of the School of Public Health (HKU), Alexandre Giorgini, Consul General of France in Hong Kong and Macau, and Diane-Sophie Trevoux, Attach?e for Education, University and Science, the evening went along in a very warm and friendly atmosphere.

Guests thanked him for his groundbreaking scientific work within the lab as well as his remarkable contribution in teaching, and highlighted how his discoveries, notably in the field of coronaviruses, have been decisive for the current response to the pandemic...

WHO remains tight-lipped on experts sent to investigate coronavirus in China

...
The WHO said last week that two experts – an animal health specialist and an epidemiologist – would start work on Saturday but by Sunday evening there was still no word on the name of the specialists, the schedule of the trip, and their agenda.
...
Yanzhong Huang, a senior fellow in global health governance, also with the Council on Foreign Relations, said a transparent investigation by the WHO could be a chance for the organisation to “rebuild its reputation and show it is an authoritative neutral actor in global health governance”.

But the “composition of the [future international] delegation, where are they going to visit, what is the plan of the investigation, this is all subject to negotiation,” he said, adding that even the WHO’s comments last week that Wuhan would be the starting point for the inquiry “is subject to negotiation or has to be decided by the Chinese side”.

Much depends on how much access the team gets to data and to investigate different scenarios, including the theory that the virus is linked to a Wuhan lab, some observers say.

Daniel Lucey, an infectious disease and outbreak expert at Georgetown University Medical Centre, said the international team would need to “adequately address” this theory.

Speculations have been going around about the coronavirus "escaping" from a lab in Wuhan. Some even say that the virus was genetically manipulated by man and has gotten out of control.

However, Mark Kortepeter, the former deputy director of the United States Army Medical Research Institute of Infectious Diseases, argues that the virus most likely spread through natural channels rather than from a "hot zone" lab.
....
Kortepeter considers two possible scenarios in the lab. He says either someone got exposed to a natural origin such as an animal, or an exposure to a manipulated virus. His theory is that it started from exposure in the natural environment. However, considering being a biodefense and Army official, he says he does not shut out the possibility of someone trying to do things for vicious intents...
 
The virus structure can only tell so much. What fuels suspicion is the sudden crackdown on communications from the labs along with the purging of their files.
Sadly the WHO is quite beholden to the national governments and hence incapable of any forceful investigation. So the clouds will linger.

That said, it is silly to blame China for the global scale of the outbreak. There was plenty of warning, but no clear understanding or leadership in much of the world.

Bolduc [Retired Army Brig. General Don Bolduc] has also echoed Trump's baseless conspiracy theory that the coronavirus may have been engineered in a lab in Wuhan, China.

"They (China) started this **** and they weren't transparent about it," Bolduc said in a March interview. "And they probably created it in a lab. And now we're stuck with it. And the whole world is stuck with it."

He later doubled down in an interview with local news outlet WMUR, arguing that the virus was "probably a biological program they put together and it got beyond their ability to contain" and that it was designed to have a "a fatal effect on our older generation."...

...Bolduc, a 33-year U.S. Army veteran and retired Brigadier General, made the comment to reporters during a conference call in which he said he is qualified to deal with the coronavirus outbreak based on his experience dealing with the Ebola outbreak in 2014, when he led the U.S. Special Operations Command in Africa.

“China created this worldwide epidemic,” Bolduc said.

Bolduc said he agreed with the view Cotton, who has endorsed Bolduc, expressed about a month ago that the outbreak was, Bolduc said, “probably a biological program they put together and it got beyond their ability to contain.”

He said it was probably an attempt at population control, which, he said, could be “weaponized during a conflict.”

“The virus was designed to get the younger generation sick and designed to have a fatal effect on our older generation,” Bolduc said, adding that by taking seriously the idea – which has been disputed and debunked by some scientists – he did not feel that he was buying into “a conspiracy theory.”

In a brief follow up interview, Bolduc reconfirmed his belief.

“Anything is possible in the way the Chinese have been behaving,” he said. “You can’t trust the numbers they’re reporting. There are labs outside of Wuhan,” the Chinese city where the coronavirus outbreak is believed to have begun. “I am leaning toward supporting Sen. Cotton.”

Bolduc said his experience in Africa qualifies him to help people to understand the spread of the coronavirus.

He said he has no criticism of the way the federal government is dealing with the crisis and called for an end to partisan criticism...

Trump ‘owes us an apology.’ Chinese scientist at the center of COVID-19 origin theories speaks out

The coronavirus pandemic has thrust virologist Shi Zhengli into a fierce spotlight. Shi, who’s been nicknamed “Bat Woman,” heads a group that studies bat coronaviruses at the Wuhan Institute of Virology (WIV), in the city in China where the pandemic began, and many have speculated that the virus that causes COVID-19 accidentally escaped from her lab—a theory promoted by U.S. President Donald Trump. Some have even suggested it could have been engineered there.

China has forcefully rejected such claims, but Shi (pronounced SHIH) herself has said very little publicly.

Now, Shi has broken her silence about the details of her work. On 15 July, she emailed Science answers to a series of written questions about the virus’ origin and the research at her institute. In them, Shi hit back at speculation that the virus leaked from WIV. She and her colleagues discovered the virus in late 2019, she says, in samples from patients who had a pneumonia of unknown origin. “Before that, we had never been in contact with or studied this virus, nor did we know of its existence,” Shi wrote.

Science shared Shi’s responses—available here in full (PDF)—with several leading researchers in other countries. “It’s a big contribution,” says Daniel Lucey of Georgetown University, an outbreak specialist who blogs about SARS-CoV-2 origin issues. “There are a lot of new facts that I wasn’t aware of. It’s very exciting to hear this directly from her.”

Shi’s answers were coordinated with public information staffers at the Chinese Academy of Sciences, of which WIV is part, and it took her 2 months to prepare them. Evolutionary biologist Kristian Andersen of Scripps Research says he suspects Shi’s answers were “carefully vetted” by the Chinese government. “But they’re all logical, genuine, and stick to the science as one would have expected from a world-class scientist and one of the leading experts on coronaviruses,” Andersen says.

However, Richard Ebright, a molecular biologist at Rutgers University, New Brunswick, who from the early days of the pandemic has urged that an investigation look into the possibility that SARS-CoV-2 entered humans through a laboratory accident, was decidedly unimpressed. “Most of these answers are formulaic, almost robotic, reiterations of statements previously made by Chinese authorities and state media,” Ebright says...
