The origin of SARS-CoV-2, revisited

Since early in the pandemic, scientists have overwhelmingly concluded that the evidence makes a natural origin for SARS-CoV-2, the coronavirus that causes COVID-19, a far more likely explanation for the pandemic than a laboratory origin. Over the last three weeks or so, however, there has been considerable chatter about the “lab leak” hypothesis, and President Biden even ordered US intelligence agencies to…

A “not antivaccine” antivax pediatrician asks how we will know a COVID-19 vaccine is safe and effective

Dr. Liz Mumper is associated with Robert F. Kennedy, Jr.’s antivax organization Children’s Health Defense. She recently gave a presentation asking: How will we know that a COVID vaccine is safe? It’s a presentation that provides an excellent example of how to identify if someone is antivaccine.

The American Abyss

America will not survive the big lie just because a liar is separated from power. It will need a thoughtful repluralization of media and a commitment to facts as a public good. The racism structured into every aspect of the coup attempt is a call to heed our own history. Serious attention to the past helps us to see risks but also suggests future possibility. We cannot be a democratic republic if we tell lies about race, big or small. Democracy is not about minimizing the vote nor ignoring it, neither a matter of gaming nor of breaking a system, but of accepting the equality of others, heeding their voices and counting their votes.

Denial Is the Heartbeat of America

When have Americans been willing to admit who we are?

We must stop the heartbeat of denial and revive America to the thumping beat of truth. The carnage has no chance of stopping until the denial stops. This is not who we are must become, in the aftermath of the attack on the U.S. Capitol: This is precisely who we are. And we are ashamed. And we are aggrieved at what we’ve done, at how we let this happen. But we will change. We will hold the perpetrators accountable. We will change policy and practices. We will radically root out this problem. It will be painful. But without pain there is no healing.

And in the end, what will make America true is the willingness of the American people to stare at their national face for the first time, to open the book of their history for the first time, and see themselves for themselves—all the political viciousness, all the political beauty—and finally right the wrongs, or spend the rest of the life of America trying.

This can be who we are.

Coronavirus: why we’re using llamas to help fight the pandemic

The search is on for effective treatments to combat the unprecedented COVID-19 pandemic. Given the lengthy development process for vaccines, one major immediate priority is the development of selective antibodies that can neutralise the SARS-CoV-2 virus responsible for COVID-19. And a particularly exciting new advance is the recent development of “nanobody” technology.

Nanobodies are smaller, more stable types of antibody taken from the immune systems of camelid species – such as llamas, alpacas and camels – that could be more effective at fighting disease. A recent report confirmed that llama nanobodies could neutralise the SARS and MERS viruses and could also be engineered to fight SARS-CoV-2.

Since 2015, the University of Reading has collaborated with several academic and industry partners to generate specialised nanobodies from llamas. We currently keep a herd of 15 llamas at the university, including a recent unexpected arrival in the form of a cria (baby llama), whose mother surprised everyone when her pregnancy was discovered.

The timing of the birth coincided with the leadership contest of the UK Conservative Party in July 2019 and an online poll was launched to name the cria “Boris” or “Jeremy” after the candidates Johnson and Hunt. Jeremy won on this occasion and so baby Jeremy has joined the effort to discover new nanobodies, along with older llamas such as Fifi, who is leading our search for COVID nanobodies.

Our aim is to generate llama nanobodies that bind to proteins in the SARS-CoV-2 virus. These proteins include the “spike” glycoprotein that enables the virus to enter human cells, so these nanobodies could help neutralise it.

We inject the llamas with isolated proteins from the virus and then collect samples of their blood containing nanobodies produced in response by the immune system. Because we are only injecting individual proteins not the entire virus, the animals are not infected. We work with a range of partners, including those at the University of Oxford, Rosalind Franklin Institute and Francis Crick Institute, who extract and test the nanobodies and then reproduce them at a larger scale.

This strategy was recently given a boost by the report that researchers in the US and Belgium had generated llama nanobodies that bind to the spike protein of the SARS-CoV-1 and MERS-CoV coronaviruses behind the SARS and MERS diseases, respectively. What was particularly encouraging was that researchers also demonstrated that engineered nanobodies could neutralise these viruses, but also SARS-CoV-2, in the lab.

They also noted that a conventional antibody (called CR3022), another one that is good at binding to the SARS-CoV-2 spike protein, was unable to neutralise the virus in the same way that the llama nanobody was able to.

Now the hope is that similar llama nanobodies directed specifically against the SARS-CoV-2 version of the spike protein – and potentially against an additional range of viral proteins – may hold the key to combating COVID-19. The next step would be to trial the nanobodies in small animals and then non-human primates.

If this is successful, the authors of the report estimate the first tests of their nanobodies in humans could occur in around one year’s time. Due to their small size, nanobodies could potentially be converted into a fine spray (nebulised) and inhaled – ideal for a respiratory disease such as COVID-19.

Tiny defenders

Llama nanobodies have several potential advantages over conventional antibodies. Each type of antibody is a large compound consisting of “light” and “heavy” chains of molecules, some parts of which are always the same and some parts of which vary between individual antibodies. By contrast, nanobodies consist only of the variable part of heavy chain (VHH).

The VHH region is the “business” part of the molecule, responsible for binding to whatever invader it was created to fight. This means nanobodies can have similar neutralising function to their larger antibody relatives without the extra baggage that other chains add. As a result, nanobodies may be able to access targets that conventional antibodies cannot reach and better avoid detection by the virus. Nanobodies are also more stable in response to heat or chemical attack.

Nanobodies can be produced, stored and even stockpiled as needed. Their properties mean they can be used to bind to and stabilise protein molecules, such as those that may cause disease in the body. The first nanobody drug, capacizumab, was approved in 2018 and binds to a protein present in human blood to prevent a rare blood clotting disease.

There are also other ways in which a nanobody used against a coronavirus protein could be useful. If a nanobody can bind to a viral protein then this could allow gathering of detailed information about the structure of the protein and how it is presented within the virus.

This could help in the development of new drugs that may treat the infection. Llama nanobodies might also be used to develop much-needed, efficient and rapid diagnostic tests.

Because our work involves animals, it’s important to note that the University of Reading is a signatory to the Concordat on Openness on Animal Research in the UK. In 2019, the university won an Openness Award for its llama research social media campaign. The university is also committed to the principles of “the 3Rs”, working to replace, reduce and refine procedures on animals.

Coronavirus, ‘Plandemic’ and the seven traits of conspiratorial thinking

No matter the details of the plot, conspiracy theories follow common patterns of thought.

The conspiracy theory video “Plandemic” recently went viral. Despite being taken down by YouTube and Facebook, it continues to get uploaded and viewed millions of times. The video is an interview with conspiracy theorist Judy Mikovits, a disgraced former virology researcher who believes the COVID-19 pandemic is based on vast deception, with the purpose of profiting from selling vaccinations.

The video is rife with misinformation and conspiracy theories. Many high-quality fact-checks and debunkings have been published by reputable outlets such as Science, Politifact and FactCheck.

As scholars who research how to counter science misinformation and conspiracy theories, we believe there is also value in exposing the rhetorical techniques used in “Plandemic.” As we outline in our Conspiracy Theory Handbook and How to Spot COVID-19 Conspiracy Theories, there are seven distinctive traits of conspiratorial thinking. “Plandemic” offers textbook examples of them all.

Learning these traits can help you spot the red flags of a baseless conspiracy theory and hopefully build up some resistance to being taken in by this kind of thinking. This is an important skill given the current surge of pandemic-fueled conspiracy theories.

The seven traits of conspiratorial thinking.

1. Contradictory beliefs

Conspiracy theorists are so committed to disbelieving an official account, it doesn’t matter if their belief system is internally contradictory. The “Plandemic” video advances two false origin stories for the coronavirus. It argues that SARS-CoV-2 came from a lab in Wuhan – but also argues that everybody already has the coronavirus from previous vaccinations, and wearing masks activates it. Believing both causes is mutually inconsistent.

2. Overriding suspicion

Conspiracy theorists are overwhelmingly suspicious toward the official account. That means any scientific evidence that doesn’t fit into the conspiracy theory must be faked.

But if you think the scientific data is faked, that leads down the rabbit hole of believing that any scientific organization publishing or endorsing research consistent with the “official account” must be in on the conspiracy. For COVID-19, this includes the World Health Organization, the U.S. Centers for Disease Control and Prevention, the Food and Drug Administration, Anthony Fauci… basically, any group or person who actually knows anything about science must be part of the conspiracy.

3. Nefarious intent

In a conspiracy theory, the conspirators are assumed to have evil motives. In the case of “Plandemic,” there’s no limit to the nefarious intent. The video suggests scientists including Anthony Fauci engineered the COVID-19 pandemic, a plot which involves killing hundreds of thousands of people so far for potentially billions of dollars of profit.

4. Conviction something’s wrong

Conspiracy theorists may occasionally abandon specific ideas when they become untenable. But those revisions tend not to change their overall conclusion that “something must be wrong” and that the official account is based on deception.

When “Plandemic” filmmaker Mikki Willis was asked if he really believed COVID-19 was intentionally started for profit, his response was “I don’t know, to be clear, if it’s an intentional or naturally occurring situation. I have no idea.”

He has no idea. All he knows for sure is something must be wrong: “It’s too fishy.”

5. Persecuted victim

Conspiracy theorists think of themselves as the victims of organized persecution. “Plandemic” further ratchets up the persecuted victimhood by characterizing the entire world population as victims of a vast deception, which is disseminated by the media and even ourselves as unwitting accomplices.

At the same time, conspiracy theorists see themselves as brave heroes taking on the villainous conspirators.

6. Immunity to evidence

It’s so hard to change a conspiracy theorist’s mind because their theories are self-sealing. Even absence of evidence for a theory becomes evidence for the theory: The reason there’s no proof of the conspiracy is because the conspirators did such a good job covering it up.

7. Reinterpreting randomness

Conspiracy theorists see patterns everywhere – they’re all about connecting the dots. Random events are reinterpreted as being caused by the conspiracy and woven into a broader, interconnected pattern. Any connections are imbued with sinister meaning.

For example, the “Plandemic” video suggestively points to the U.S. National Institutes of Health funding that has gone to the Wuhan Institute of Virology in China. This is despite the fact that the lab is just one of many international collaborators on a project that sought to examine the risk of future viruses emerging from wildlife.

Learning about common traits of conspiratorial thinking can help you recognize and resist conspiracy theories.

Critical thinking is the antidote

As we explore in our Conspiracy Theory Handbook, there are a variety of strategies you can use in response to conspiracy theories.

One approach is to inoculate yourself and your social networks by identifying and calling out the traits of conspiratorial thinking. Another approach is to “cognitively empower” people, by encouraging them to think analytically. The antidote to conspiratorial thinking is critical thinking, which involves healthy skepticism of official accounts while carefully considering available evidence.

Understanding and revealing the techniques of conspiracy theorists is key to inoculating yourself and others from being misled, especially when we are most vulnerable: in times of crises and uncertainty.
