Controversial new research suggests SARS-CoV-2 bears signs of genetic engineering

The claim has yet to be peer-reviewed writes The Economist

Illustration of a coronavirus particle attacked by antibodies (immunoglobulin). Coronaviruses cause several diseases in humans, including covid-19, SARS and forms of the common cold.

Astring of about 30,000 genetic letters were all that it took to start the nightmare of covid-19, the death toll from which is likely to be more than 20m. Exactly how this story began has been hotly contested. Many think that covid-19’s emergence was a zoonosis—a spillover, as so many new pathogens are, from wild animals, for it resembles a group of coronaviruses found in bats. Others have pointed to the enthusiastic coronavirus engineering going on in laboratories around the world, but particularly in Wuhan—the Chinese city where the virus was first identified. In February 2021 a team of scientists assembled by the World Health Organisation (who) to visit Wuhan said a laboratory leak was extremely unlikely. However, this conclusion was subsequently challenged by the who’s boss, who said ruling out this theory was premature.

Two recent publications appear to have bolstered the case for a natural origin connected to a “wet market” in Wuhan. These markets sell live animals, often housed in poor conditions, and are known to be sites where new pathogens jump from animal to human. Early cases of covid-19 clustered around this market. But critics counter that there are so many missing data about the epidemic’s initial days that this portrait may be inaccurate.

The opposing idea of a leak from a laboratory is not implausible. The accidental escape of viruses from labs is more common than many people realise. The flu epidemic of 1977 is thought to have started this way. But an escaped virus does not imply an engineered virus. Virology labs are also full of the unengineered sort.

Research such as that done in Wuhan offers a number of ways for a virus to leak out. A researcher on a field trip could have picked it up in the wild and then returned to Wuhan, and so spread it to others there. Or someone might have been infected with a wild-collected virus in the laboratory itself. But some argue that sars-cov-2 could have been assembled in a laboratory from other viruses that were already to hand, and then leaked out.

Into this fray comes an analysis from an unlikely source. Alex Washburne is a mathematical biologist who runs Selva, a small startup in microbiome science based in New York. He is an outsider, although he has worked in the past on virological modelling as a researcher at Montana State University. For this study, Dr Washburne collaborated with two other scientists. One is Antonius VanDongen, an associate professor of pharmacology at Duke University, in North Carolina. The other, Valentin Bruttel, is a molecular immunologist at the University of Würzburg, Germany. Dr Washburne and Dr VanDongen have been active proponents of an investigation into the lab-leak theory.

The trio base their claim on a novel method of detecting plausibly lab-engineered viruses. Their analysis, published on October 20th on bioRxiv, a preprint server, suggests sars-cov-2 has some genomic features that they say would appear if the virus had been stitched together by some form of genetic engineering. By examining how many of these putative stitching sites sars-cov-2 has, and how relatively short these pieces are, they attempt to assess how much the virus resembles others found in nature.

They start from the presumption that creating a genome as long as that of sars-cov-2 would mean combining shorter fragments of existing viruses together. For a coronavirus genome assembly they say an ideal arrangement would be to use between five and eight fragments, all under 8,000 letters long. Such fragments are created using restriction enzymes. These are molecular scissors which cut genomic material at particular sequences of genetic letters. If a genome does not have such restriction sites in opportune places, researchers typically create new ones of their own.

They argue that the distribution of restriction sites for two popular restriction enzymes—BsaI and BsmBI—are “anomalous” in the sars-cov-2 genome. And the length of the longest fragment is far shorter than would be expected. They determined this by taking 70 disparate coronavirus genomes (not including sars-cov-2) and cutting them into pieces with 214 commonly used restriction enzymes. From the resulting collection, they were able to work out the expected lengths of fragments when coronaviruses are cut into varying numbers of pieces.

The paper, which as a preprint has received no formal peer review, and which has not been accepted for publication in a journal, will be picked apart in the coming days—as well it should be, for this is the way that science works. Early reactions, though, have been deeply divided. Francois Balloux, a professor of computational systems biology at University College London, said he found the results intriguing. “Contrary to many of my colleagues, I couldn’t identify any fatal flaw in the reasoning and methodology. The distribution of BsaI/BsmBI restriction sites in sars-cov-2 is atypical”. Dr Balloux said these needed to be assessed in good faith. But Edward Holmes, an evolutionary biologist and virologist at the University of Sydney, said that every one of the features identified by the paper was natural and already found in other bat viruses. If someone were engineering a virus they would undoubtedly introduce some new ones. He added, “there are a whole range of technical reasons why this is complete nonsense.”

Sylvestre Marillonnet, an expert in synthetic biology at the Leibniz Institute for Plant Biochemistry, in Germany, agreed that the number and distribution of these restriction sites did not look quite random, and that the number of silent mutations found in these sites did suggest that sars-cov-2 might have been engineered. (Silent mutations are a result of engineers wanting to make changes in a sequence of genetic material without making changes to the proteins encoded by that sequence.) But Dr Marillonnet also said that there are arguments against this hypothesis. One of them is the tiny length of one of the six fragments, something that “does not seem logical to me”.

The other point Dr Marillonnet makes is that it is not necessary for the restriction sites to have been present in the final sequence. “Why would people introduce and leave sites in the genome when it is not needed?” he wondered. Previous arguments in support of the possibility of a lab leak have stressed that a manipulated virus would not need to have any such tell-tales. However, Justin Kinney, a professor at Cold Spring Harbor Laboratory, in New York, said that researchers have created coronaviruses before and left such sites in the genome. He said the genetic signature indicates a virus ready for further experiments and said it needed to be taken seriously, but warned the paper needed rigorous peer review.

Erik van Nimwegen, from the University of Basel, says there are only small scraps of information and it is “hard to pull anything definitive out of that”. He adds, “one cannot really exclude at all that such a constellation of sites may have occurred by chance”. The authors of the paper concede this is the case. Kristian Andersen, a professor of immunology and microbiology, at the Scripps Research Institute in La Jolla, California, described the pattern, on Twitter, as “random noise”.

Any conclusion that sars-cov-2 was engineered will be hotly contested. China denies the virus came from a Chinese lab, and has asked for investigations into whether it may have originated in America. Dr Washburne and his colleagues say their predictions are testable. If a progenitor genome to sars-cov-2 is found in the wild with restriction sites that are the same, or intermediate, it would raise the chances that this pattern evolved by chance.

Any widely supported conclusion that the virus was genetically engineered would have profound ramifications, both political and scientific. It would put in a new light the behaviour of the Chinese government in the early days of the outbreak, particularly its reluctance to share epidemiological data from those days. It would also raise questions about what was known, when, and by whom about the presumably accidental escape of an engineered virus. For now, this is a first draft of science, and needs to be treated as such. But the scrutineers are already at work.

If the Wuhan lab-leak hypothesis is true, expect a political earthquake

There was a time when the Covid pandemic seemed to confirm so many of our assumptions. It cast down the people we regarded as villains. It raised up those we thought were heroes. It prospered people who could shift easily to working from home even as it problematized the lives of those Trump voters living in the old economy.

Like all plagues, Covid often felt like the hand of God on earth, scourging the people for their sins against higher learning and visibly sorting the righteous from the unmasked wicked. “Respect science,” admonished our yard signs. And lo!, Covid came and forced us to do so, elevating our scientists to the highest seats of social authority, from where they banned assembly, commerce, and all the rest.

We cast blame so innocently in those days. We scolded at will. We knew who was right and we shook our heads to behold those in the wrong playing in their swimming pools and on the beach. It made perfect sense to us that Donald Trump, a politician we despised, could not grasp the situation, that he suggested people inject bleach, and that he was personally responsible for more than one super-spreading event. Reality itself punished leaders like him who refused to bow to expertise. The prestige news media even figured out a way to blame the worst death tolls on a system of organized ignorance they called “populism.”

But these days the consensus doesn’t consense quite as well as it used to. Now the media is filled with disturbing stories suggesting that Covid might have come — not from “populism” at all, but from a laboratory screw-up in Wuhan, China. You can feel the moral convulsions beginning as the question sets in: What if science itself is in some way culpable for all this?

*

I am no expert on epidemics. Like everyone else I know, I spent the pandemic doing as I was told. A few months ago I even tried to talk a Fox News viewer out of believing in the lab-leak theory of Covid’s origins. The reason I did that is because the newspapers I read and the TV shows I watched had assured me on many occasions that the lab-leak theory wasn’t true, that it was a racist conspiracy theory, that only deluded Trumpists believed it, that it got infinite pants-on-fire ratings from the fact-checkers, and because (despite all my cynicism) I am the sort who has always trusted the mainstream news media.

My own complacency on the matter was dynamited by the lab-leak essay that ran in the Bulletin of the Atomic Scientists earlier this month; a few weeks later everyone from Doctor Fauci to President Biden is acknowledging that the lab-accident hypothesis might have some merit. We don’t know the real answer yet, and we probably will never know, but this is the moment to anticipate what such a finding might ultimately mean. What if this crazy story turns out to be true?

The answer is that this is the kind of thing that could obliterate the faith of millions. The last global disaster, the financial crisis of 2008, smashed people’s trust in the institutions of capitalism, in the myths of free trade and the New Economy, and eventually in the elites who ran both American political parties. 

In the years since (and for complicated reasons), liberal leaders have labored to remake themselves into defenders of professional rectitude and established legitimacy in nearly every field. In reaction to the fool Trump, liberalism made a sort of cult out of science, expertise, the university system, executive-branch “norms,” the “intelligence community,” the State Department, NGOs, the legacy news media, and the hierarchy of credentialed achievement in general.

Now here we are in the waning days of Disastrous Global Crisis #2. Covid is of course worse by many orders of magnitude than the mortgage meltdown — it has killed millions and ruined lives and disrupted the world economy far more extensively. Should it turn out that scientists and experts and NGOs, etc. are villains rather than heroes of this story, we may very well see the expert-worshiping values of modern liberalism go up in a fireball of public anger.

Consider the details of the story as we have learned them in the last few weeks:

  • Lab leaks happen. They aren’t the result of conspiracies: “a lab accident is an accident,” as Nathan Robinson points out; they happen all the time, in this country and in others, and people die from them.
  • There is evidence that the lab in question, which studies bat coronaviruses, may have been conducting what is called “gain of function” research, a dangerous innovation in which diseases are deliberately made more virulent. By the way, right-wingers didn’t dream up “gain of function”: all the cool virologists have been doing it (in this country and in others) even as the squares have been warning against it for years.
  • There are strong hints that some of the bat-virus research at the Wuhan lab was funded in part by the American national-medical establishment — which is to say, the lab-leak hypothesis doesn’t implicate China alone.
  • There seem to have been astonishing conflicts of interest among the people assigned to get to the bottom of it all, and (as we know from Enron and the housing bubble) conflicts of interest are always what trip up the well-credentialed professionals whom liberals insist we must all heed, honor, and obey.
  • The news media, in its zealous policing of the boundaries of the permissible, insisted that Russiagate was ever so true but that the lab-leak hypothesis was false false false, and woe unto anyone who dared disagree. Reporters gulped down whatever line was most flattering to the experts they were quoting and then insisted that it was 100% right and absolutely incontrovertible — that anything else was only unhinged Trumpist folly, that democracy dies when unbelievers get to speak, and so on.
  • The social media monopolies actually censored posts about the lab-leak hypothesis. Of course they did! Because we’re at war with misinformation, you know, and people need to be brought back to the true and correct faith — as agreed upon by experts.
*

“Let us pray, now, for science,” intoned a New York Times columnist back at the beginning of the Covid pandemic. The title of his article laid down the foundational faith of Trump-era liberalism: “Coronavirus is What You Get When You Ignore Science.”

Ten months later, at the end of a scary article about the history of “gain of function” research and its possible role in the still ongoing Covid pandemic, Nicholson Baker wrote as follows: “This may be the great scientific meta-experiment of the 21st century. Could a world full of scientists do all kinds of reckless recombinant things with viral diseases for many years and successfully avoid a serious outbreak? The hypothesis was that, yes, it was doable. The risk was worth taking. There would be no pandemic.”

Except there was. If it does indeed turn out that the lab-leak hypothesis is the right explanation for how it began — that the common people of the world have been forced into a real-life lab experiment, at tremendous cost — there is a moral earthquake on the way.

Because if the hypothesis is right, it will soon start to dawn on people that our mistake was not insufficient reverence for scientists, or inadequate respect for expertise, or not enough censorship on Facebook. It was a failure to think critically about all of the above, to understand that there is no such thing as absolute expertise. Think of all the disasters of recent years: economic neoliberalism, destructive trade policies, the Iraq War, the housing bubble, banks that are “too big to fail,” mortgage-backed securities, the Hillary Clinton campaign of 2016 — all of these disasters brought to you by the total, self-assured unanimity of the highly educated people who are supposed to know what they’re doing, plus the total complacency of the highly educated people who are supposed to be supervising them.

Then again, maybe I am wrong to roll out all this speculation. Maybe the lab-leak hypothesis will be convincingly disproven. I certainly hope it is.

But even if it inches closer to being confirmed, we can guess what the next turn of the narrative will be. It was a “perfect storm,” the experts will say. Who coulda known? And besides (they will say), the origins of the pandemic don’t matter any more. Go back to sleep.

Why the suspicion on China’s Wuhan lab virus is growing

 Tara Kartha in The Print

It’s been nearly eighteen months since the coronavirus brought the world on its knees, with India in the middle of a deadly second wave that is claiming 4,000 lives daily on an average. No one can tell when this will end. But it is possible to probe how this catastrophe began, and China’s role in it. Fortunately, even as cover ups go on. Several reports are out in the public domain and anybody who isn’t afraid of speaking the truth should be able to connect the dots.

One report out is that of the Independent Panel, set up by a resolution of the 73rd World Health Assembly. The specific mission of the committee was to review the response of the World Health Organization (WHO) to the Covid outbreak and the timelines relevant. In other words, it was never meant to be an inquisition on China. And it wasn’t. Not by a long chalk. It went around the core question of the origin of the virus, even while indulging in what seems to be pure speculation. Then there are two recent publications investigating the origin of the virus, which are worthy of note. Neither are written by sage scientists, but by analysts viewing the whole sequence of events through the prism of intelligence. Which means that these efforts skip the big words, and get to the facts. Collate all these different sources, add a little more of the background colour, and you start to get the big picture. 

Is this biological warfare?

The need to find out the truth becomes urgent as the situation worsens, for instance with dangerously high death rates in Aligarh Muslim University, where there is now speculation whether the deaths could be linked to a separate strain. There are arguments that India’s second wave could be a deliberate one, especially since the ‘double mutant’ has not hit any of its neighbours. Such speculation is likely to rise, given that China has now effectively closed any possibility of withdrawal from Ladakh, and the Chinese economy goes from strength to strength, growing a record 18.3 per cent in the first quarter of the new financial year. Unsurprisingly, even world leaders, like Brazil’s President Jair Bolsonaro, have linked the pandemic to biological warfare.

Arising from this is the biggest potential danger: someone may decide to respond in kind in a bid to fix Beijing. That’s how intelligence operations work. After all, major countries haven’t been funding their top secret labs for nothing. In any scenario, there’s some serious trouble ahead, especially since the Narendra Modi government seems to be more intent on playing down the crisis than addressing it. 

The Independent Panel 

The panel’s mandate is set out clearly in the May 2020 resolution, which calls for “a stepwise process of impartial, independent and comprehensive evaluation…to review experience gained and lessons learned from the WHO-coordinated international health response to COVID-19…” and thereafter provide recommendations. This the panel undoubtedly did.

The 13-member panel included former Prime Minister of New Zealand Helen Clark, former President of Liberia who has core expertise in setting up health care after Ebola, an award winning feminist, a former WHO bureaucrat, and a former Indian health secretary, who had six months experience in handling the first Covid wave, was on innumerable panels on health, and in the manner of civil servants in this country, also did a stint in the Ministry of Defence, not to mention the World Bank. The Indian representative certainly gives the whole exercise the imprimatur of legality, given hostile India-China relations. And finally, Zhong Nanshan who was advisor to the Chinese government during the Wuhan outbreak, and who received the highest State honour of the Medal of the Republic from his President—Xinhua describes him as a “brave and outspoken” doctor.

The WHO also lists Peng Liyuan as a Goodwill Ambassador, describing her as a famous opera singer. She is the wife of President Xi Jinping. It’s,therefore, entirely unsurprising that while the panel diligently shows WHO the sources of early warning, it makes a vague case on the origins of the virus, noting that while a species of bat was “probably” the host, the intermediate cycle is unknown. Most astonishingly, the committee states that the virus “may already have been in circulation outside China in the last months of 2019”. No evidence for that either. The overall tenor of the report is that it would take years to sort all this out.

There is only one paragraph of note from the point of view of those seeking the truth.

The panel’s report states that less than 55–60 per cent of early cases had been exposed to the wet markets, and that the area merely “amplified” the virus. In other words, the market, with its hundreds of exotic wildlife, could not have been the source. It, however, carefully notes that the Wuhan Institute of Virology (WIV) sequenced the entire genome of the virus almost within weeks, and later provided this to a public access source. The report praises the diligence of clinicians who managed to isolate the virus within a short time. That’s wonderful all right. No question. But it doesn’t at all address the question whether those diligent researchers were also experimenting on the virus. 

That troubling question

These assessments by the Independent Panel are now, however, being questioned, leading to bits of intelligence being pieced together from within a country that would put the term ‘Iron curtain’ to shame. An earlier WHO study on the virus’ origin was roundly condemned by a group of countries,including the US, Australia, Canada and others (not India) as being duplicitous in the extreme.

In January 2021, the US Department of State released a Fact Sheet on activity of WIV, which is entirely based on intelligence. That factsheet is damning, indicating that several researchers at the institute had fallen ill with characteristics of the Covid virus, thus showing up senior Chinese researcher Shi Zhengli’s claim that there was “zero infection” in the lab. The lab was the centre of research of the SARS virus since its first outbreak, including on ‘RaTG13’ virus found in bats, and which is 96 per cent similar to the present virus SARS-COV-2. Worst, it also pointed out that “the United States has determined that the WIV has collaborated on publications and secret projects with China’s military. The WIV has engaged in classified research, including laboratory animal experiments, on behalf of the Chinese military since at least 2017”.

That’s intelligence. Now for the analysis — the two recent publications probing the virus’ origin. 

Disaggregating the facts 

One analytical article is published in the prestigious Bulletin of the Atomic Scientists. Another is a paper by the equally reputed Begin Sadat Centre for Strategic Studies. Both are a careful collation of facts, and establish the following.

The paper by Begin Sadat Centre brings out additional information that bolsters the US Fact Sheet. It appears that the US had been able to get a ‘source’ from WIV directly, and that another Chinese scientist had defected to an unknown European country. That led directly to information on the military side of the programme. The study also quotes David Asher, who led the Department of State investigation. Asher observes that the WIV had two campuses, not one, as popularly believed. This was known by the Indian authorities for years, but does not seem to have been put about. Asher also adds that all mention of the SARS virus was dropped from the institute’s publicly admitted biological “defence programmes” by 2017 at the same time when the Level 4 lab kicked off operations.

Even more surprising was that an adjacent facility had already administered vaccines to its senior faculty in March 2020 itself. That doesn’t suggest an accident. That suggests a program that was designed to kill, and for which vaccines were already under research. Then there damning studies stated: “There are plenty of indications in the sequence itself that [the initial pandemic virus] may have been synthetically altered. It has the backbone of a bat [coronavirus], combined with a pangolin receptor binder, combined with some sort of humanized mice transceptor. These things don’t actually make sense (and) …..the odds this could be natural are very low… [but this is attainable] through deliberate scientific ‘gain of function research” that was going on at the WIV.

There is no doubt that ‘gain of function’ research is practised in biological research labs world over, resulting in, sometimes, dangerous incidents. This type of research involves in-crossing viruses, ostensibly to gain knowledge on how to battle the disease from within. In these cases, it’s almost impossible to decide where the ‘defence’ aspect leaches into an offensive capability. That these findings were from US scientists who were ‘fearful’ of being quoted shows not just the extent of Beijing’s clout in university research and funding, but also a high degree of restraint. Biological research is almost never talked about. 

The denials begin

Biological research and the secrecy around it is the aspect of focus in Nicholas Wade’s article published in Bulletin of the Atomic Scientists. As he writes, from the beginning, there was denial at the highest levels from some unexpected quarters. The first was in The Lancet— one of the oldest journals of medical research—by a group of authors in March 2020, when the pandemic had just broken out. Even to a layman, it would have seemed that it was far too early for the group of authors to contemptuously dismiss ‘conspiracy theories’ that the virus was not of a natural origin.

It turns out that The Lancet letter was drafted by Peter Daszak, President of the EcoHealth Alliance of New York, who’s organisation funded corona virus research at the Wuhan lab. As is pointed out in Wade’s article, any revelation of such a connection would have been criminal to say the least, if it was proved that the virus did escape from the lab. Unsurprisingly, Daszak was also part of the WHO team investigating the origins of the virus.

Another burst of outrage came from a group of professors who also hurried to disprove, in an article, the ‘lab created’ theory on the grounds – simply put – that it was not of the most probably calculated design. The lead author Kristian G Anderson is from the Scripps Research Institute, La Jolla, which specialises in biomedical research. It also has partnerships with Chinese labs and pharma companies. None of that is criminal. Especially when Scrippsis already in financial distress at the time.  Besides, such collaborations are not restricted to just US labs. See, for instance, an account of Australian doctor Dominic Dwyer, who was part of the first WHO study, and who dismissed without any evidence presented that the virus had leaked from a lab.

Dwyer’s claim that the Wuhan lab seems to have been run well, and that nobody from the facility seemed to have fallen sick has now been disputed. Evidence of a dangerous virus escaping a lab – as it has in the past on what he calls “rare” occasions – would mean a death blow to labs everywhere. Funding is, after all, hard to come by. Then there is the nice hard cash involved. The Harvard professor Dr Charles Leiber who was arrested, together with two other Chinese, for collaborating quietly with the Wuhan University of Technology (WUT), was being paid roughly $50,000 per month, living expenses of up to 1,000,000 Chinese Yuan (approximately $158,000) and awarded $1.5 million to establish a research lab at WUT.  He was also asked to ‘cultivate’ young teachers and Ph.D. students by organising international conferences.

It’s all very pally and friendly, and a lot of money is involved. The end result? A virus out of hell, that seems not to affect the Chinese as its economy powers ahead and shifts its weight more comfortably into its rising position in the global order.

Covid lies cost lives – we have a duty to clamp down on them

George Monbiot in The Guardian

Why do we value lies more than lives? We know that certain falsehoods kill people. Some of those who believe such claims as “coronavirus doesn’t exist”, “it’s not the virus that makes people ill but 5G”, or “vaccines are used to inject us with microchips” fail to take precautions or refuse to be vaccinated, then contract and spread the virus. Yet we allow these lies to proliferate.

We have a right to speak freely. We also have a right to life. When malicious disinformation – claims that are known to be both false and dangerous – can spread without restraint, these two values collide head-on. One of them must give way, and the one we have chosen to sacrifice is human life. We treat free speech as sacred, but life as negotiable. When governments fail to ban outright lies that endanger people’s lives, I believe they make the wrong choice.

Any control by governments of what we may say is dangerous, especially when the government, like ours, has authoritarian tendencies. But the absence of control is also dangerous. In theory, we recognise that there are necessary limits to free speech: almost everyone agrees that we should not be free to shout “fire!” in a crowded theatre, because people are likely to be trampled to death. Well, people are being trampled to death by these lies. Surely the line has been crossed?

Those who demand absolute freedom of speech often talk about “the marketplace of ideas”. But in a marketplace, you are forbidden to make false claims about your product. You cannot pass one thing off as another. You cannot sell shares on a false prospectus. You are legally prohibited from making money by lying to your customers. In other words, in the marketplace there are limits to free speech. So where, in the marketplace of ideas, are the trading standards? Who regulates the weights and measures? Who checks the prospectus? We protect money from lies more carefully than we protect human life.

I believe that spreading only the most dangerous falsehoods, like those mentioned in the first paragraph, should be prohibited. A possible template is the Cancer Act, which bans people from advertising cures or treatments for cancer. A ban on the worst Covid lies should be time-limited, running for perhaps six months. I would like to see an expert committee, similar to the Scientific Advisory Group for Emergencies (Sage), identifying claims that present a genuine danger to life and proposing their temporary prohibition to parliament.

While this measure would apply only to the most extreme cases, we should be far more alert to the dangers of misinformation in general. Even though it states that the pundits it names are not deliberately spreading false information, the new Anti-Virus site www.covidfaq.co might help to tip the balance against people such as Allison Pearson, Peter Hitchens and Sunetra Gupta, who have made such public headway with their misleading claims about the pandemic.

But how did these claims become so prominent? They achieved traction only because they were given a massive platform in the media, particularly in the Telegraph, the Mail and – above all – the house journal of unscientific gibberish, the Spectator. Their most influential outlet is the BBC. The BBC has an unerring instinct for misjudging where debate about a matter of science lies. It thrills to the sound of noisy, ill-informed contrarians. As the conservationist Stephen Barlow argues, science denial is destroying our societies and the survival of life on Earth. Yet it is treated by the media as a form of entertainment. The bigger the idiot, the greater the airtime.

Interestingly, all but one of the journalists mentioned on the Anti-Virus site also have a long track record of downplaying and, in some cases, denying, climate breakdown. Peter Hitchens, for example, has dismissed not only human-made global heating, but the greenhouse effect itself. Today, climate denial has mostly dissipated in this country, perhaps because the BBC has at last stopped treating climate change as a matter of controversy, and Channel 4 no longer makes films claiming that climate science is a scam. The broadcasters kept this disinformation alive, just as the BBC, still providing a platform for misleading claims this month, sustains falsehoods about the pandemic.

Ironies abound, however. One of the founders of the admirable Anti-Virus site is Sam Bowman, a senior fellow at the Adam Smith Institute (ASI). This is an opaquely funded lobby group with a long history of misleading claims about science that often seem to align with its ideology or the interests of its funders. For example, it has downplayed the dangers of tobacco smoke, and argued against smoking bans in pubs and plain packaging for cigarettes. In 2013, the Observer revealed that it had been taking money from tobacco companies. Bowman himself, echoing arguments made by the tobacco industry, has called for the “lifting [of] all EU-wide regulations on cigarette packaging” on the grounds of “civil liberties”. He has also railed against government funding for public health messages about the dangers of smoking.

Some of the ASI’s past claims about climate science – such as statements that the planet is “failing to warm” and that climate science is becoming “completely and utterly discredited” – are as idiotic as the claims about the pandemic that Bowman rightly exposes. The ASI’s Neoliberal Manifesto, published in 2019, maintains, among other howlers, that “fewer people are malnourished than ever before”. In reality, malnutrition has been rising since 2014. If Bowman is serious about being a defender of science, perhaps he could call out some of the falsehoods spread by his own organisation.

Lobby groups funded by plutocrats and corporations are responsible for much of the misinformation that saturates public life. The launch of the Great Barrington Declaration, for example, that champions herd immunity through mass infection with the help of discredited claims, was hosted – physically and online – by the American Institute for Economic Research. This institute has received money from the Charles Koch Foundation, and takes a wide range of anti-environmental positions.

It’s not surprising that we have an inveterate liar as prime minister: this government has emerged from a culture of rightwing misinformation, weaponised by thinktanks and lobby groups. False claims are big business: rich people and organisations will pay handsomely for others to spread them. Some of those whom the BBC used to “balance” climate scientists in its debates were professional liars paid by fossil-fuel companies.

Over the past 30 years, I have watched this business model spread like a virus through public life. Perhaps it is futile to call for a government of liars to regulate lies. But while conspiracy theorists make a killing from their false claims, we should at least name the standards that a good society would set, even if we can’t trust the current government to uphold them.

A virus that kills cancer: the cure that's waiting in the cold


On the snow-clotted plains of central Sweden where Wotan and Thor, the clamorous gods of magic and death, once held sway, a young, self-deprecating gene therapist has invented a virus that eliminates the type of cancer that killed Steve Jobs.
'Not "eliminates"! Not "invented", no!' interrupts Professor Magnus Essand, panicked, when I Skype him to ask about this explosive achievement.
'Our results are only in the lab so far, not in humans, and many treatments that work in the lab can turn out to be not so effective in humans. However, adenovirus serotype 5 is a common virus in which we have achieved transcriptional targeting by replacing an endogenous viral promoter sequence by…'
It sounds too kindly of the gods to be true: a virus that eats cancer.
'I sometimes use the phrase "an assassin who kills all the bad guys",' Prof Essand agrees contentedly. 
Cheap to produce, the virus is exquisitely precise, with only mild, flu-like side-effects in humans. Photographs in research reports show tumours in test mice melting away.
'It is amazing,' Prof Essand gleams in wonder. 'It's better than anything else. Tumour cell lines that are resistant to every other drug, it kills them in these animals.'
Yet as things stand, Ad5[CgA-E1A-miR122]PTD – to give it the full gush of its most up-to-date scientific name – is never going to be tested to see if it might also save humans. Since 2010 it has been kept in a bedsit-sized mini freezer in a busy lobby outside Prof Essand's office, gathering frost. ('Would you like to see?' He raises his laptop computer and turns, so its camera picks out a table-top Electrolux next to the lab's main corridor.)
Two hundred metres away is the Uppsala University Hospital, a European Centre of Excellence in Neuroendocrine Tumours. Patients fly in from all over the world to be seen here, especially from America, where treatment for certain types of cancer lags five years behind Europe. Yet even when these sufferers have nothing else to hope for, have only months left to live, wave platinum credit cards and are prepared to sign papers agreeing to try anything, to hell with the side-effects, the oncologists are not permitted – would find themselves behind bars if they tried – to race down the corridors and snatch the solution out of Prof Essand's freezer.
I found out about Prof Magnus Essand by stalking him. Two and a half years ago the friend who edits all my work – the biographer and genius transformer of rotten sentences and misdirected ideas, Dido Davies – was diagnosed with neuroendocrine tumours, the exact type of cancer that Steve Jobs had. Every three weeks she would emerge from the hospital after eight hours of chemotherapy infusion, as pale as ice but nevertheless chortling and optimistic, whereas I (having spent the day battling Dido's brutal edits to my work, among drip tubes) would stumble back home, crack open whisky and cigarettes, and slump by the computer. Although chemotherapy shrank the tumour, it did not cure it. There had to be something better.
It was on one of those evenings that I came across a blog about a quack in Mexico who had an idea about using sub-molecular particles – nanotechnology. Quacks provide a very useful service to medical tyros such as myself, because they read all the best journals the day they appear and by the end of the week have turned the results into potions and tinctures. It's like Tommy Lee Jones in Men in Black reading the National Enquirer to find out what aliens are up to, because that's the only paper trashy enough to print the truth. Keep an eye on what the quacks are saying, and you have an idea of what might be promising at the Wild West frontier of medicine. This particular quack was in prison awaiting trial for the manslaughter (by quackery) of one of his patients, but his nanotechnology website led, via a chain of links, to a YouTube lecture about an astounding new therapy for neuroendocrine cancer based on pig microbes, which is currently being put through a variety of clinical trials in America.
I stopped the video and took a snapshot of the poster behind the lecturer's podium listing useful research company addresses; on the website of one of these organisations was a reference to a scholarly article that, when I checked through the footnotes, led, via a doctoral thesis, to a Skype address – which I dialled.
'Hey! Hey!' Prof Magnus Essand answered.
To geneticists, the science makes perfect sense. It is a fact of human biology that healthy cells are programmed to die when they become infected by a virus, because this prevents the virus spreading to other parts of the body. But a cancerous cell is immortal; through its mutations it has somehow managed to turn off the bits of its genetic programme that enforce cell suicide. This means that, if a suitable virus infects a cancer cell, it could continue to replicate inside it uncontrollably, and causes the cell to 'lyse' – or, in non-technical language, tear apart. The progeny viruses then spread to cancer cells nearby and repeat the process. A virus becomes, in effect, a cancer of cancer. In Prof Essand's laboratory studies his virus surges through the bloodstreams of test animals, rupturing cancerous cells with Viking rapacity.
The Uppsala virus isn't unique. Since the 1880s, doctors have known that viral infections can cause dramatic reductions in tumours. In 1890 an Italian clinician discovered that prostitutes with cervical cancer went into remission when they were vaccinated against rabies, and for several years he wandered the Tuscan countryside injecting women with dog saliva. In another, 20th-century, case, a 14-year-old boy with lymphatic leukaemia caught chickenpox: within a few days his grotesquely enlarged liver and spleen had returned to ordinary size; his explosive white blood cell count had shrunk nearly 50-fold, back to normal.
But it wasn't until the 1990s, and the boom in understanding of genetics, that scientists finally learnt how to harness and enhance this effect. Two decades later, the first results are starting to be discussed in cancer journals.
So why is Magnus – did he mind if I called him 'Magnus'? – about to stop his work?
A reticent, gently doleful-looking man, he has a Swedish chirrup that makes him sound jolly whatever his actual mood. On the web, the first links to him proclaim the Essand Band, his rock group. 'Money,' he said. 'Lack of.'
'Lack of how much money? Give me a figure,' I pressed. 'What sort of price are we talking about to get this virus out of your freezer and give these people a chance of life?'
Magnus has light brown hair that, like his voice, refuses to cooperate. No matter how much he ruffles it, it looks politely combed. He wriggled his fingers through it now, raised his eyes and squinted in calculation, then looked back into his laptop camera. 'About a million pounds?'
More people have full-blown neuroendocrine tumours (known as NETs or carcinoids) than stomach, pancreas, oesophagus or liver cancer. And the incidence is growing: there has been a five-fold increase in the number of people diagnosed in the last 30 years.
In medical school, students are taught 'when you hear hoof beats, think horses not zebras' – don't diagnose a rare disease when there's a more prob-able explanation. It leads to frequent misdiagnoses: until the death of Steve Jobs, NETs were considered the zebras of cancer, and dismissed as irritable bowel syndrome, flu or the patient getting in a tizz. But doctors are now realising that NETs are much more prevalent than previously thought. In a recent set of post-mortem investigations, scientists cut open more than 30,000 bodies, and ran their hands down the intestines of the dead as if they were squeezing out sausage skins. One in every 100 of them had the distinctive gritty bumps of NETs. That's two people in every rush-hour tube carriage on your way home from work, or scaled up, 700,000 people in Britain, or roughly twice the population of the city of Manchester. The majority of these tumours are benign; but a small percentage of them, for reasons that no one understands, burst into malignancy.
Many other cancers, if they spread, acquire certain features of neuroendocrine tumours. The first person to own a successful anti-neuroendocrine cancer drug – it doesn't even have to cure the disease, just slow its progress as anti-retrovirals have done with Aids – will be not only healthy but also Steve Jobs-rich. Last year the pharmaceuticals giant Amgen bought a cancer-assassinating version of the herpes virus for $1 billion. That Magnus's virus could be held up by a minuscule £1 million dumbfounded me.
'That's a banker's bonus,' I said. 'Less than a rock star's gold toilet seat. It's the best bargain going. If I found someone to give you this money, would you start the clinical trials?'
'Of course,' replied Magnus. 'Shall I ask the Swedish Cancer Board how soon we can begin?'
I do not have a million pounds. But for £68 I flew to Uppsala. I wanted to pester Prof Essand about his work, face to face, and see this virus, face to petri dish. I wanted to slip some into my mittens, smuggle it back to England in an ice pack and jab it into Dido.
Magnus's work is already funded by the Swedish Cancer Society and the Swedish Children Cancer Society (neuroblastoma, the most common cancer in infants, is a type of neuroendocrine tumour). A virus that he previously developed (against prostate cancer) is about to enter human trials in Rotterdam, supported by a European Union grant.
The difficulty with Magnus's virus is not that it is outré, but that it is not outré enough. It is a modified version of an adenovirus, which is known to be safe in humans. It originates from humans, occurring naturally in the adenoids. The disadvantage is that it is too safe: the immune system has had thousands of years to learn how to dispatch such viruses the moment they stray out of the adenoids. It is not the fact that Magnus is using a virus to deal with cancer that makes his investigation potentially so valuable, but the novel way he has devised to get round this problem of instant elimination by the immune system, and enable the virus to spread through tumours in other parts of the body.
The closer you get to manipulating the cellular forces of human existence, the more you sound like a schoolboy babbling about his model aeroplane. Everything in the modern genetics lab is done with kits. There are no fizzing computer lights or fractionating columns dribbling out coagulations of genetic soup in Magnus's lab; not a single Bunsen burner. Each narrow laboratory room has pale, uncluttered melamine worktops running down both sides, wall units above and small blue cardboard cartons dotted everywhere. Even in their genetics labs, Swedes enjoy an air of flatpack-ness. The most advanced medical lab in the world, and it looks like a half-fitted kitchen.
To make and test their virus, Magnus buys cell lines pre-fab (including 'human foreskin fibro-blast') for $50-100 from a company in California; DNA and 'enzyme mix' arrive in $179 packets from Indiana; protein concentrations are tested 'according to the manufacturer's instructions' with a DIY kit ($117) from Illinois; and for $79, a parcel from Santa Cruz contains (I haven't made this up) 'horseradish peroxidase conjugated donkey anti-goat antibody'.
In a room next to Magnus's office, a chatty woman with a ponytail is putting DNA inside bacteria. This God-like operation of primal delicacy involves taking a test tube with a yellow top from a $146 Qiagen kit, squirting in a bit of liquid with a pipette and putting the result in a box similar to a microwave: 'turn the dial to 25 kilovolts and oophlah! The bacteria, they get scared, they let the DNA in. All done,' the woman says. As the bacteria divide, the desirable viral fragments increase.
What costs the £1 million (less than two per cent of the price of Francis Bacon's Triptych 1976) that Magnus needs to bring this medicine to patients is not the production, but the health-and-safety paperwork to get the trials started. Trials come in three phases. What Magnus was suggesting for his trifling £1 million (two Mont Blanc diamond-encrusted pens) was not just a phase I trial, but also a phase II, which, all being well, would bring the virus right to the point where a big pharmaceuticals company would pay 10 or 100 times as much to take it over and organise the phase III trial required by law to presage full-scale drug development.
'So, if Calvin Klein or Elton John or… Paris Hilton stumped up a million, could they have the virus named after them?'
'Why not?' Magnus nodded, showing me the bacteria incubator, which looks like an industrial clothes washer, only less complicated. 'We can make an even better one for two million.'
There are reasons to be cautious. A recent investigation by Amgen found that 47 of 53 papers (on all medical subjects, not just viruses) by academics in top peer-reviewed science journals contained results that couldn't be reproduced, even though company scientists repeated the experiments up to 50 times. 'That's why we have to have such a careful peer-review process,' Dr Tim Meyer, Dido's energetic, soft-spoken oncologist, warns. 'Everybody thinks that their new treatment for cancer is worth funding, but everybody is also keen that only good-quality research is funded.' Similar to Prof Essand in youth but less polite of hair, Dr Meyer is the co-director of the Experimental Cancer Medicine Centre at University College London. Beside his office, banks of white-coated researchers are bent over desks, busy with pipettes and microscopes. His team pursues an exciting brew of new anti-cancer ideas: antibody-targeted therapy, vascular therapy, DNA binding agents and photodynamic therapy. Each of these shows remarkable promise. But even for such a brilliant and innovative team as this, money is not flowing.
Everyone in cancer science is fighting for ever-decreasing small pools of cash, especially now the government has started tiptoeing into charities at night and rifling the collection boxes. It is big news that Dr Meyer and the UCL team won a grant of £2.5 million, spread out over the next five years, to continue his institute's cutting-edge investigations into cancers that kill off thousands of us every week: leukaemia; melanoma; gynaecological, gastrointestinal and prostate cancers. Without this money, he would have had to sack 13 members of staff. The sum of £2.5 million is roughly what Madonna earns in 10 days.
He peers at Magnus's pairs of photographs of splayed rodents with glowing tumours in one shot that have vanished in the next. He knows the Uppsala neuroendocrine team well and has great respect for them. 'It may be good,' he agrees. But until Magnus's findings are tested in a clinical trial, nobody knows how good the work is. Astonishing results in animals are often disappointing in humans. 'We all need to be subject to the same rules of competitive grant funding and peer review in order to use scarce resources in the most effective manner.'
Back at home with whisky and fags, I nursed my entrepreneurialism. There are currently about half a dozen cancer research institutes in Europe developing adenoviruses to treat cancer – all of them pathetically short of cash. Enter the Vanity Virus Initiative. Pop a couple of million over to Uppsala University, and you will go down in medical books as the kind heart who relieved Ad5[CgA-E1A-miR122]PTD of its hideous hump of a moniker, and gave it the glamour of your own name. What's the worst that can happen? Even if Magnus's innovations don't work in clinical trials the negative results will be invaluable for the next generation of viruses. For the rest of time, your name will pop up in the reference sections of medical papers as the (insert your name here) virus that enabled researchers to find the cure for cancer by avoiding Magnus's error.
On my third glass of whisky, I wrote an email to Dr Meyer suggesting that he issue a shopping list each year at the time that bankers receive their bonuses, which could be circulated in the City. The list would itemise the therapies that his Experimental Cancer Medicine Centre have selected for support, and quantify how much would be needed in each case to cover all outstanding funds and ensure that the work is branded with your name.
The corridors connecting the different research departments of the Uppsala medical campus are built underground, in order to protect the staff from death during the Swedish winters. Professors and lab technicians zip back and forth along these enormous rectangular tunnels on scooters, occasionally scratching their heads at the tangled intersections where three or four passageways meet at once, then pushing off again, gowns flying, one leg pounding the concrete floor like a piston, until they find the right door, drop the scooter and rise back upstairs by lift. Suspended from the ceiling of these corridors is a vacuum tube that schluuuuups up tissue samples at top speed, and delivers them to the appropriate investigative team. Magnus led me along these tunnels to the Uppsala University Hospital, to visit the chief oncologist, Kjell (pronounced 'Shell') Oberg – the man who will run the trial once the money is in place.
'The trouble with Magnus's virus is Magnus is Swedish,' he says, wincing and clutching the air with frustration.
'It is so,' Magnus agrees sorrowfully. Swedishly uninterested in profiteering, devoted only to the purity of science, Magnus and his co-workers on this virus have already published the details of their experiments in leading journals around the world, which means that the modified virus as it stands can no longer be patented. And without a patent to make the virus commercial, no one will invest. Even if I could raise the £2 million (I want only the best version) to get the therapy to the end of phase II trials, no organisation is going to step forward to run the phase III trial that is necessary to make the therapy public.
'Is that because pharmaceuticals companies are run by ruthless plutocrats who tuck into roast baby with cranberry sauce for lunch and laugh at the sick?' I ask sneerily.
'It is because,' Kjell corrects me, 'only if there's a big profit can such companies ensure that everyone involved earns enough to pay their mortgage.'
There is no ready source of public funds, either. For reasons understood only by Wotan and Thor, the Swedish government refuses to finance clinical trials in humans, even when the results could potentially slash the country's health bill by billions of kronor.
All is not lost, however. Kjell does not have to wait until the end of the trials – which could take as much as 10 years – for the full, three-phase process before being able to inject Magnus's virus into his patients, because as soon as the test samples are approved and ready for use, he can by European law start offering the medicine, on an individual basis, to patients who sign a waiver confirming that they're prepared to risk experimental treatments. Within 18 months he could be starting his human case-studies.
At several moments during my research into this cancer-delaying virus from the forests of Scandinavia I have felt as though there were someone schlocky from Hollywood operating behind the scenes. The serendipitous discovery of it on the internet; the appalling frustration of being able to see the new therapy, to stand with my hand against the freezer door knowing that it is three inches away, not well-guarded, and that it might work even in its crude current state, but that I may not use it; the thrill of Kjell Oberg's powerful
support; the despair over the lack of such a silly, artificial thing as a patent. Now, Dr Leja steps into the narrative: she is the virologist whose brilliant doctoral thesis first put me on to the cancer-eating-virus-left-in-a-freezer, and whose name heads all the subsequent breakthrough research papers about this therapy. She turns out to be 29, to look like Scarlett Johansson and to wear voluptuous red lipstick.
Justyna Leja slinks up from her chair, shakes my hand and immediately sets off into a baffling technical discussion with Magnus about a good way to get the patent back for the virus, by a subtle manipulation that involves something called a 'new backbone'. She also has in mind a small extra tweak to the new-backboned microbe's outer coat, which will mean that the virus not only bursts the cancer cells it infects, but also provokes the immune system to attack tumours directly. It will be easy to see if it works in animals – but is it worth lumbering the current virus with it for use in humans, who tend to be less responsive? The extra preparatory work could delay the phase I and II trials for a further year.
Back at his lab, Magnus opened up the infamous freezer. I took a step towards the plastic flasks of virus: he nipped the door shut with an appreciative smile.
'What would you do,' I asked bitterly, returning my hand to my pocket, 'if it were your wife who had the disease, or one of your sons whose photograph I saw on your desk?'
He glanced back at the freezer. Although his lab samples are not made to pharmaceutical grade, they would be only marginally less trustworthy than a fully-sanctioned, health-and-safety certified product that is between 1,000 and 10,000 times more expensive.
'I don't know,' he groaned, tugging his hair in despair at the thought. 'I don't know.'
