Scientists claim to find HIV virus-like insertions in the 2019-nCov [pdf] (biorxiv.org)

Sorry, but it's very easy to verify that these claims are crap by replicating their study, i.e. doing a simple blast search of the insert sequence against the virus database. Here's the result of the first insert: https://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Get&RID=398N4CS...

Although, there are some hits against HIV, there are also equally matching hits against bacteriophages; viruses that only target bacterias, they are completely unrelated to any viruses that target humans and animals. Furthermore, the E value is around 170, that means that matches are statistically completely insignificant, meaning they happened by chance only. Such a high E value corresponds to a p-value of very, very close to 1 (https://www.ncbi.nlm.nih.gov/BLAST/tutorial/Altschul-1.html).

These guys that published such a paper are either completely clueless or nefarious in trying to stir up conspiracy theories.


What's the chance of hitting all 4 of them though? This is a good step in verification but you are awfully too quick to reject their claim.


Read the paper, they actually only match 2 inserts, the other two inserts are modified by the authors in such a way that they are made to match (Table 1).

Both inserts 1 and 2 also match to Streptococcus phage, but a bacteriophage would of course not be such a bold claim as HIV matches are.

Also, be aware that because of the scientific interest in HIV, there are hundreds of HIV strains sequenced, a virus known for its mutation rate (especially in these two proteins gp120 and gag, as they are under pressure to mutate in order to evade the immunesystem). So in such a large library of protein sequences one is bound to find a match of a short 6 letter (amino acid) sequence. That's why E values exist to make a statement about the statistical significance.


For posteriority, here's the link to the Blast results for the second insert: https://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Get&RID=39ACRKV...


Hello posteriority here! I wanted to reference these comments in a discussion but the links expired :/


Large HIV database inflating matches is indeed a big concern. But dismissing one miss matches sounds arbitrary: these segments were not arbitrarily selected, but real insertions on tops of sars.


Again, take any random six letter amino acid sequence and chances are high that it matches to some HIV protein.

I just did the experiment with my first name that is coincidentally 6 letters long, and lo and behold: a match to HIV env protein!

Has my first name now been designed by a bioweapons facility?


> Has my first name now been designed by a bioweapons facility?

No, of course not. Your parents were designed by a bioweapons facility, so that they would choose that name.

;-)


You revealed my secret


Large (but <100) evalues are sometimes considered as weak evidence of some evolutionary process if you are querying against a huge database with closely related sequences. However, given the length of their first 2 hits I'd tend to think this is by random chance. The last 2 are more interesting.

And the fact that there's no known CoV with any of these inserts is quite intriguing.


The last two (look at table 1) are interesting in such a way that its almost scientific misconduct akin to photoshopping a picture in a scientific paper. They blasted the inserts, but apparently couldn't find any matches to HIV, so they just changed them until they found something.


>These guys that published such a paper are either completely clueless or nefarious in trying to stir up conspiracy theories.

In your opinion, do you think this kind of subterfuge could have been picked up by Dr. Eric Feigl-Ding or someone with a similar calibre, before broadcasting this preprint for wider consumption? Thanks.


I have not heard from this guy before (I work in microbial genomics, he seems to be in the field of health economics from a quick search), so I can't comment on that.


Outside of the assertion that it is related to HIV, does the original argument around deliberate insertions hold any water?


Occam's razor says no. The coronavirus spike protein is responsible for receptor binding and entry into the cell. Different strains with different hosts bind to different receptors, so they have differences in their spike protein sequences. Mutations in the spike protein are expected in the evolution of coronavirus.


Your reply is much appreciated.


This looks like a whole lot of rubbish to me. They're excited they managed to get blast hits for these short inserts.

But in the spirit of open-mindedness, what do I need to be convinced this is even interesting? First I want to see where on gp120 these inserts align to. Are they receptor/carbohydrate binding regions? Where do they map to on the coronavirus? These structures are known, so I don't know why this isn't in this manuscript.

If somehow this is engineered, I am honestly impressed that someone could take features from one protein and estimate how to engineer those same features in another protein altogether, with little homology. It's like engineering a monkey tail onto an elephant and somehow getting the elephant to swing through the trees.


I appreciate your skepticism (and your sense of humor) but for the benefit of other readers, it is not like engineering a monkey tail onto an elephant and expecting the elephant to swing through the trees.


I think the important things to know here are:

1. A group of scientist have submitted a manuscript for review with a number of exceptionally (and uncharacteristically) bold claims.

2. A huge amount of scrutiny and additional reproducibility will necessarily need to be conducted before conclusions of this nature can be drawn.

3. This manuscript hasn't even passed the normal muster... a biorxiv post isn't much different than a Medium post. Claims like these require many eyes.

EDIT: My sentiment echoed by someone who know more than I https://twitter.com/DrEricDing/status/1223325141364592640?s=...


As regards #3, I agree: the more eyes who see this unconfirmed claim, the better. That's the main reason I upvoted the OP.

A great outcome would be if reputable scientists see this on HN or Twitter or learn about it through colleagues, and subsequently refute it or dismiss it as bad science.


> the more eyes who see this unconfirmed claim, the better.

Isn't it a waste of those eyes' time if it turns out to be false? When there are plenty of confirmed things they could be reading?


#2: replicating their BLAST search is easy: https://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Get&RID=398N4CS... and it shows that the matches of these short inserts are completely by chance and don't constitute any statistically significant relationship.


Thank you for posting this here -- and thank you for taking a quick look at that paper and debunking it.

I just upvoted your comment at https://news.ycombinator.com/item?id=22206393.


This is especially interesting since there have been reports that China was testing HIV treatments on patients with the coronavirus:

https://www.reuters.com/article/us-china-health-abbvie-hiv/c...


Yes they are BUT it's my understanding those HIV drugs had already been used against SARS and found helpful in an anecdotal way. So it would be an obvious first go-to drug.


HIV drugs were used on SARS over a decade ago. https://www.ncbi.nlm.nih.gov/pubmed/15144898

It shouldn't be surprising that this new virus that is related to SARS can also be treated by HIV antiviral drugs.


A thread by an epidemiologist on the new results:

https://twitter.com/DrEricDing/status/1223305946723704832


This has been pointed out in previous threads, but this Twitter is full of alarmist unscientific BS and it appears to be spammed with some regularity on HN recently.


Alarmist, yes. Unscientific BS, not really. He’s got the background to make comments from a position of legitimacy. If we can’t trust this guy, even with some healthy skepticism, who should we trust?

https://scholar.harvard.edu/ericding/home

Edit: by trust, I don’t mean blindly believe, but mean one should consider his comments seriously.


From that link, it seems like he is commenting far outside of his expertise in "behavioral interventions" to improve things like "medicare cost."

Don't trust anyone, just weigh their claims and their background. In this case, I have yet to see people with serious credentials in genomics make this claim (outside of the original scientists who published the paper relating it to HIV - IIT is impressive, but I don't really know how to assess their credentials writ large)


How is this outside his area of expertise? He has a doctorate in epidemiology.

He graduated from The Johns Hopkins University with Honors in Public Health and Phi Beta Kappa. He then completed his dual doctorate in epidemiology and doctorate in nutrition, as the youngest graduate to complete his dual program at age 23 from Harvard SPH. Teaching at Harvard for over 15 years, he has advised and mentored 2 dozen students, and lectured in more than a dozen graduate and undergraduate courses, for which he received the Derek Bok Distinction in Teaching Award from Harvard College.


That largely depends on the credibility of the source of the Twitter posts. The author in the referenced thread does seem to be a legitimate commentator on the subject.


This particular person doesn't seem to be an example of that.

https://en.wikipedia.org/wiki/Eric_Ding

He's also calling for confirmation before everyone goes nuts:

https://twitter.com/DrEricDing/status/1223325141364592640


The Twitter user seems legit. The Internet in general is full of BS yet we don't guilt-by-association the entire Internet.


We should question the veracity of the information presented. The nature of this fluid topic is a good example. I read the first part, a few days ago, and most of the information presented tallied with what was presented elsewhere. However, since then Dr. Eric Ding's profile has risen in prominence and the Twitter feed is commingling speculation with credentials, so it is entirely justified to question the validity of your source.

It would seem that there were doubts around the content in the Wikipedia entry.

What are the geopolitical ramifications if this is indeed a bioweapon?


I don't think it will be talked about in that way. Especially if this is a bioweapon created in China which accidentally escaped. No one wants the dirty laundry spilled of all the countries who are doing bioweapon research. China is too powerful economically and surely has too much dirt on everyone else to go down alone. So I believe the official position will be that it's either not engineered at all ("inconclusive"), or just an unfortunate accident related to legitimate non-weapon research. Worst case scenario is US, EU, etc. do a little finger wagging that China needs to "stop eating bats" and then it will be let go. Of course, that's just the official/public position.


China is a signatory to the Biological Weapons Convention [1]. The US State Department regularly issues a compliance report about it (and other international agreements). Here [2] is how it summarized China's compliance in August 2019:

"Information indicates that the People’s Republic of China (China) engaged during the reporting period in biological activities with potential dual-use applications, which raises concerns regarding its compliance with the BWC. In addition, the United States does not have sufficient information to determine whether China eliminated its assessed biological warfare (BW) program, as required under Article II of the Convention."

(That's followed by some more details, which you can read about in [2].)

Given this ongoing scrutiny, it would be very surprising if a smoking gun that the PRC has in fact been developing bioweapons were just swept under the rug.

[1] https://en.wikipedia.org/wiki/Biological_Weapons_Convention

[2] https://www.state.gov/wp-content/uploads/2019/08/Compliance-...


I'm making the assumption that there's a MAD situation here with regards to revealing bioweapon programs. I am assuming every major economy has clandestine bioweapon programs and that every major economy has the dirt on everyone else's bioweapons programs, regardless of treaties. So if the US, or someone else, comes out hard against China for an alleged bioweapon program, then China will release information about US programs. That is why, in my opinion, the media headlines and public positions of the major players will be a polite fiction. The truth may wind up buried in some report somewhere, but it won't make the same kinds of headlines that "kooky bat eating" makes.


One of the issues in treaty monitoring for bioweapons is that so much research is inherently dual-use. The CDC synthesized Spanish flu and infected primates to study why it was so lethal.. they've even tweaked regular strains of flu to make them more lethal, in order to study what genetic factors influence virulence and mortality. There are legitimate, compelling reasons to make even genetically engineered pathogens. Even straight-up engineered bioweapons can be used to study defenses.


Just do not leak and not under communist rule.

Even if this is not, you just cannot trust them. They leak sars in their Beijing lab

“ In fact, the SARS virus had ‘escaped’ multiple times from a lab in Beijing, according to the Nature article.”


Perhaps the US and EU will put aside squabbles caused by the trade war to have a united front against China?


Maybe this is naive, but I would assume if it was a bio-weapon it would be a lot more deadly.


Funny, I would have assumed the opposite. Nobody wins a war by releasing a doomsday virus that indiscriminately kills 5% of the world. But they can win battles by temporarily incapacitating an army, with no fear of loss of their own life if the winds blow in the opposite direction.


Viruses which kill too quickly don't spread widely enough to kill a lot of people.

Good viruses kill after a few days of showing few (if any) symptoms so that they can maximise their spread.

This is the difference between epidemic and pandemic viral contagions.


But the point of a bio weapon is not to kill everyone,just your enemy. So i guess you would want it to be very deadly and not spread to far. And i imagine you would want to primarily take out young healthy people (soldiers) not the eldery and sickly. (I assume)


This virus spreads quickly (check) but has a mortality rate of 2%, mostly the old and already immunocompromised. If that's a bioweapon it's a pretty ineffective one.


If you want to extinct homo sapiens you should probably make a virus that infects everybody and has as little symptoms as possible and then kills them a year later.

We don't know yet if this virus has any long-term consequences. HIV would seem harmless if we estimated its effects after 1 month.

But I don't think bioweapons need to be deadly. If you can make a virus that kills 2% of people but shuts down global trade with your main economic competitor for example - that's quite useful (if you don't care for morality of course).

I'm not persuaded it's human-created, but it's a possibility.


2% so far, it's very early in the lifecycle of this epidemic and most people go days without showing any symptoms.

The mortality rate will rapidly increase as it spreads to areas where it can overwhelm the local infrastructure. Not every country is capable of creating hospitals in 6 days like China, and China has a lot of experience responding to these crises since the Sars days.

We are only a month in, it's too early to really count mortality.


It might not be a bioweapon. It might be an economic weapon.


Well, it's a Made in China bio Weapon..


Why was this submission suddenly so heavily penalized by the mod(s)?


Users can press the “flag” button for content that is off-topic. I flagged this article because it is an unreviewed pre-print paper that has been rushed out by its authors, who clearly have not investigated any of the most obvious follow-up questions, such as “what is the probability of this occurring naturally?”


Okay so we definitely need to flag any machine learning papers from Arxiv because hey preprint.

Further, do you assume that other members cannot read the preprint warning and decide for themselves? This strikes me as some sort of bizarre way to patronize the entire community.


I’m not a biologist, so I’m really not interested in this type of paper, and I expressed my opinion through the voting mechanism.

Also, there are thousands of researchers studying this new virus. If this turns out to be an important finding, I can wait until it is validated. At this point, this paper looks poor quality, and it was a waste of time for me to click on it and read it.


There are no post downvotes on HN for a reason (or at least normal users dont have them) - flag doesn't and shouldn't mean the same thing as a downvote.


I don’t flag things often, as one might downvote a comment they disagree with. The flag mechanism is for off-topic or spam content, and I consider this way off-topic for this site. There have already been hundreds of published articles about this virus, and if I was interested in seeing them, I would use a site like PubMed to see them.


Need summary otherwise bad coin drive away good coins. What are the good one?


> it is an unreviewed pre-print

Any relevant work on nCoV will be unreviewed at this point.


>who clearly have not investigated any of the most obvious follow-up questions, such as “what is the probability of this occurring naturally?”

If it's true then the cause is an entirely different question.


Follow-up - this seems to be happening to other, maybe all 2019-nCoV posts, I just hadn't noticed before.

In which case they just change the title normally.. rather than penalizing it heavier than any other penalized post Ive noticed recently.


Could be automod stuff. I have read a few hypothesis a couple of times about things that can trigger automodding, like many upvotes but few comments, or lots of deeply nested comments very quickly.


Also curious about this.


I noticed this as well. Censorship...



"...unlikely to be fortuitous."

Ignoring the odd word-choice, this ties in to the conspiracy theory that this was a Wuhan biolab containment leak.

I have been writing it off as a crackpot conspiracy until now, depending on peer review.


I'm not saying I believe the conspiracies, but it would be a pretty scary future if a totalitarian nation decided to quietly immunize their population (or just a selected elite) from a pathogen designed by themselves, and if push comes to shove you have a bioweapon that will do the job for you, which you know the people you care about can't contract. It's like a smart nuke.


Given historical experimentation by the military and intelligence agencies it seems pretty likely that this sort of research is happening.


So what is the probability that a lab that works with HIV normally, now working under extreme pressure, contaminated or mixed up a sample?

And what is the probability that this is not just a third type of major coronavirus, but in fact a secret bioweapon?

Knowing how commonly there are arguments about mixed up samples in the biolabs friends work in, I know where I would place my bets.


The article claims that the new coronavirus is an "hybrid" of an usual coronavirus with some parts of HIV. If you mix both virus in a bottle of water, you don't get the hybrid.

If both virus infect a cell simultaneously, there is a small possibility that something like this happens. I think it's so small that is not possible to do it in a laboratory even on purpose, and definitively not by accident but IANAB.

It is easier with other virus. For example mixing variants of flu, because they have (IIRC) 8 strands of DNA. There are avian, swine, human, others flu, and each of them has many subvariants. If some animal get infected with two variants at the same time, a cell may have a double infection and the viral offspring may have a mix.

But the mix is a mix of the strands of DNA, like 3 swine flu + 5 human flu. This is usual, but you must consider that there are millions and millions of animals in the wild and farms. It's more difficult to do it in a small lab, but IANAB.

The main difference is that the article claim that the usual coronavirus and the HIV parts are in a single strain, not a bunch of strains packed together.


Could easily be "mixed samples" on the other end instead of intentional leaks. You know how old lab equipment could be really useful in a live seafood market.


It would be a pretty lame bioweapon given how few people it’s killed.


Be advised that there are many posts on Chinese social media claiming the crematoriums are backlogged with people whose listed cause of death is "viral pneumonia" (or just "pneumonia") because hospitals are turning away so many and diagnostics are not catching up. Do not take statistical reporting for granted: The numbers are a best case scenario of definitive knowns. Also, bioweapons have as diverse a variety of use cases as any other class of weapon: They don't need to kill half of a population to be effective weapons.


While I think China is hiding the number of infected, it'd be pretty hard to hide the proportion of dead to infected as the virus has already escaped Wuhan.


The question is not hard but no one really know. Would you test a body died recently?

China is not very reliable in gdp (one top guy told us to look at the electricity and we look at pollution). It is very hard to get stat.

So far touch wood no one died outside of China. The death rate should not be high unless the alternative saying hiv death rate after 1 month is 0%.

The conspiracy theory in a proper sense is accidentally leaked for an experiment, like sars virus leaked (later and during study) by Beijing level 3 lab.


Does anyone know the extent of the symptoms of 2019-nCoV? Does the virus get fully expelled from a person when they are recovered? Or is there a secondary effect / reemergence?


Some comments on this Biorxiv site from an epidemiologist: https://twitter.com/aetiology/status/1223328143647236097

"For non-scientists, if you see something posted from a site called BioRxiv, have some skepticism. It could be a fantastic paper! (I've used it!)--but. The site is for preprints, which means they haven't undergone peer review yet."


That's very, very disturbing.

If this is an engineered virus, why as a race do we keep doing these things to ourselves? Do we _really_ think that weapons of mass destruction won't be turned on us? Is our hubris so high that we think no one else can replicate what we built?


Our eye and hand was developed mainly to focus against other humans.

Our military has to study this ...

But officially one has to study this as dual use as one has to prepare the natural evolution of say SARS to another strain. Can’t be sitting duck, let evolution run its course (2% death rate is not high but times 1.4 billion it is 28m people). Hence there is a case to study it, even change it. But then ...

Just like we should fight hiv. But then someone in china use human to experiment on it.

It is not there is no case. There are. Just stupidity of human ...


>Is our hubris so high that we think no one else can replicate what we built?

How do we know someone else hasn't already built what we've built? They don't exactly post these things on Facebook...

....which is why we have to build it too.


If a horrible weapon can be built, it will be built. And it is better to be the one building the weapon than the one at the mercy of those who built it.


to someone who doesn’t know anything about the relevant science (me) the use of the word “insertions” seems to imply this was engineered. Can someone who actually understands this explain what this document is saying?


Well, the conclusion of this paper is that the odds of this virus coming to be naturally are very small. Which is a very scientific way of saying "we think this was man-made".

But, that is what the paper is saying. Extraordinary claims, extraordinary evidence is what I think. I feel the evidence here is quite small, but I'm not a bio-data-scientist.


Is it an extraordinary claim? The sequence matching should be easy to verify as the genome has been published. If the sequences are short or common enough maybe it would be a more likely coincidence.

That said: What are the priors on a "natural" virus erupting in the only city in China with a level 4 biohazard facility?

Source: http://english.www.gov.cn/state_council/ministries/2018/01/0...


So if it's not extraordinary it's still going to require evidence, which without peer review we still pretty much have none.


This is evidence, but it requires corroboration from other evidence. Peer review doesn't provide additional evidence - it's just a sober second opinion that lends credence (or not) to the proposed evidence and interpretation.

Just wanted to clarify the language here.


Totally right - and thank you for the clarification in language.


Indeed, the paper seems to suggest that the natural occurrence of this virus is the extraordinary claim.


> This indicates that these insertions have been preferably acquired by the 2019-nCoV, providing it with additional survival and infectivity advantage. Delving deeper we found that these insertions were similar to HIV-1. Our results highlight an astonishing relation between the gp120 and Gag protein of HIV, with 2019-nCoV spike glycoprotein. These proteins are critical for the viruses to identify and latch on to their host cells and for viral assembly (Beniac et al., 2006). Since surface proteins are responsible for host tropism, changes in these proteins imply a change in host specificity of the virus. According to reports from China, there has been a gain of host specificity in case 2019-nCoV as the virus was originally known to infect animals and not humans but after the mutations, it has gained tropism to humans as well.

> Our analysis of the spike glycoprotein of 2019-nCoV revealed several interesting findings: First, we identified 4 unique inserts in the 2019-nCoV spike glycoprotein that are not present in any other coronavirus reported till date. To our surprise, all the 4 inserts in the 2019-nCoV mapped to short segments of amino acids in the HIV-1 gp120 and Gag among all annotated virus proteins in the NCBI database. This uncanny similarity of novel inserts in the 2019- nCoV spike protein to HIV-1 gp120 and Gag is unlikely to be fortuitous. Further, 3D modelling suggests that atleast 3 of the unique inserts which are non-contiguous in the primary protein sequence of the 2019-nCoV spike glycoprotein converge to constitute the key components of the receptor binding site. Of note, all the 4 inserts have pI values of around 10 that may facilitate virus-host interactions. Taken together, our findings suggest unconventional evolution of 2019-nCoV that warrants further investigation. Our work highlights novel evolutionary aspects of the 2019-nCoV and has implications on the pathogenesis and diagnosis of this virus.

So, maybe, maybe not. What's the likelihood of natural occurences resulting in these inserts ? Are these novel evolutionary aspects natural or engineered ?

Can't outright say "It was made in a lab" but can say "Something's new here".


Insertions can occur naturally.

https://en.wikipedia.org/wiki/Insertional_mutagenesis

> Because many viruses integrate their own genomes into the genomes of their host cells in order to replicate, mutagenesis caused by viral infections is a fairly common occurrence. Not all integrating viruses cause insertional mutagenesis, however.

This paper does seem to allege that these particular sets of insertions aren't via natural causes, though.


There could be naturally occurring insertions, but they would generally look similar to an associated coronavirus, or something else local, not 4 discrete changes that are all nearly identical to a (very well studied) virus that should be completely unrelated..



The amazing thing is last week someone on 4chan posted this: https://i.imgur.com/Jkq8tYK.png Which shows that the virus had been modified. 4chan wins once again at sleuthing.


This lab theory has been systematically censored across the internet for the last week or so. For me it has been fascinating to watch content on it pop up and then disappear.


Psyberwar in action...


Maybe I'm missing something obvious but nothing in that image shows the virus has been modified? Or at least the commentary doesn't say that.


The study is probably bunk and sensational. check the comments by this redditor : https://www.reddit.com/r/China_Flu/comments/ewt9ep/scientifi...

https://www.reddit.com/r/China_Flu/comments/ewuotw/discussio...

The real question is: how far are we from this becoming real ?


Interesting, that user claims to be especially familiar with the 'gag' protein where the paper claims to find a match. User explicitly says that the "matching" portions claimed in the paper are so tiny as to be negligible, and not unique to HIV. They claim that this is easily verifiable with a simple 'blast' search. Could someone comment on these claims?



I BLASTed all 4 2019-nCoV insert sequences and agree with that user. The sequences are short and found in many other proteins. It is appropriate to trim out the gaps (relative to the HIV sequences) in inserts 3 & 4, reducing the length of the query. In other words, we have 4 sequences of lengths: 6, 6, 8, & 12 amino acids, where the alphabet of naturally occurring amino acids is N=20. Amino acid frequency in proteins in non-uniform.


Ignoring the political implications, how would HIV insertions change the virulence and epidemiology of the infection?


In the paper they hypothesize:

> Due to the presence of gp120 motifs in 2019-nCoV spike glycoprotein at its binding domain, we propose that these motif insertions could have provided an enhanced affinity towards host cell receptors. Further, this structural change might have also increased the range of host cells that 2019-nCoV can infect.


I wonder if this could happen because someone with a retrovirus got both infections at once?


It's not even necessarily someone with HIV - HIV is just one virus that is especially well-studied. If horizontal gene transfer in viruses is more common than we expect it to be, this genetic material could've been picked up from just about anywhere and we wouldn't necessarily know about that source.


This would be a really scary outcome. As has been commented elsewhere, there's confirmed events of at least four virus leaks from labs in Beijing.

Evidence/article on it here:

https://thebulletin.org/2014/03/threatened-pandemics-and-lab...

Not only that, but just last year there was a case of a Chinese scientist who was banished from a Canadian bio lab level 4 for stealing virus samples, as well as a Harvard Academic found to be taking money from the Chinese gov to help develop the lab in Wuhan.

None of this proves the lab theory, but I do believe that with enough genetic analysis the truth will come out.


I don't like how people are saying that theories regarding it being accidentally leaked are conspiratorial in nature.

Intentional leaking? Sure, I think it's fair to consider that a conspiracy theory. But not accidental.


I know that specifically on reddit, most posts related to the lab theory are deleted on the main pages and subreddits for this virus. For me it's been fascinating to watch the curation and deletion of content that has been evolving over the last few days.

I agree that anything with intentional leaking is really far into conspiracy theory land, but the idea that it was a leak is not so crazy.


It would be conspiratorial in nature because it questions the Chinese government's official narrative that the virus emerged from a seafood market, and implies they're covering up the truth.

Of course, people usually use the term "conspiratorial" to be synonymous with "untrue" or even "patently absurd."


We already know for sure that the initial cases did not originate in the seafood market and that the market was just an infection vector for subsequent cases.

Recently available data shows that the first few cases happened in November.


> None of this proves the lab theory

The attempted and partially continued cover-up and downplaying of the outbreak does add a significant amount of credence to the theory.


How long would it take for any other scientists to confirm or deny this?


Maybe we should wait for peer review before we jump to any conclusions.


I generally agree with the folks who flagged this posting on HN (I didn't though) because the thought of ... airborne, highly contagious HIV in an early phase pandemic ... is a really very un-HN-like thought ... the mere theoretical possibility it could be true is the sort of thing I'd hope might inspire a generation to make our leaders globally take a time out on heated rhetoric and the ongoing technological arms race.



My dose of speculation. So far we have strong evidence that this is a biolab virus, probably they were experimenting with this virus on animals the lab personal didn't realize on time how easy this virus could be transmitted by air, probably they were using the public transport from home to work during the incubation period thats how it boomed all of a sudden.


It does seem like something escaped a lab or a human trial gone wrong. Here's a better explanation: https://jameslyonsweiler.com/2020/01/30/on-the-origins-of-th...


2019-nCov is "The novel coronavirus (2019-nCoV), informally known as the Wuhan coronavirus."

source: https://en.wikipedia.org/wiki/Novel_coronavirus_(2019-nCoV)


This is all just guys stirring up trouble, conspiracy theories abound.


The virus is real. How it spread and where it comes from is an important analysis needed. SARS seems from eating wild cat and they are not sold there (there after decade there are selling in that market still but not those type).

You learn. But so far due to the source is far away from more reliable scientific base (hk in 2003), no one knows. Hence one have to reconstruct.

These might be wrong but investigation is needed. “ For his contemporaries, the ideas presented by Copernicus were not markedly easier to use than the geocentric theory and did not produce more accurate predictions of planetary positions. ”

Let the river flow. Dead water you can step in twice is not good water.


Have in mind that this paper is not peer reviewed.


"The finding of 4 unique inserts in the 2019-nCoV, all of which have identity /similarity to amino acid residues in key structural proteins of HIV-1 is unlikely to be fortuitous in nature."

Does this lend support to the theory that the coronavirus was engineered in Wuhan's bioweapons laboratory?


If that is ever proven and a cover up ensues I’d like to think the people would at last slough off their gov.


I'm not sure that realizing your totalitarian government is more dangerous and less principled than you thought is going to encourage rebellion.

Very true but but people are better informed and are no longer powerless peasants and roboter. They have a bit more self determination.


Worse than creating a super plague?


Yes? https://en.wikipedia.org/wiki/Great_Leap_Forward

> A lower-end estimate is 18 million and upper estimates find that some 45 million people died.

That's more than virtually all epidemics. Black Death, Spanish flu, and (maybe) HIV exceed it.


Harvesting organs from political prisoners is pretty bad.

Happening by a lucky chance.

It's implying it was inserted on purpose... (Sorry had to look up that meaning.)

Detecting intelligent design in things is done all the time. Teacup dachshunds are intelligently designed. So's corn and broccoli.

Throwing your hands up and saying "God must've done it!" when you don't have an immediate explanation and can't be bothered to do some research into one is the bad science part.

A religious flamewar on top of whatever else we've got here is the last thing this thread needs!


Fair enough! I don't seem to be able to delete it; please feel free.

"Intelligent design" is an argument for the existence of God, which is a religious topic.

The issue from an HN moderation point of view isn't religion; it's religious flamewar, which is what internet arguments about religion—at least in large public forums—inevitably degrade into. Therefore we don't go there.


Intelligent design is the theory that it is possible to detect intelligent intervention, as an explanation for specified complexity. Some use the theory to argue for the existence of God, but there are also atheists like Thomas Nagel who promote the theory. So, the theory itself is orthoginal to religion,and is properly a scientific or philosophical topic. Both science and philosophy are well within the scope of HN discussions.


> there are also atheists like Thomas Nagel who promote the theory.

Well, if there are atheists who do so, they are in that respect specifically not like Thomas Nagel. While Nagel does endorse certain criticisms of the consensus models made by proponents of intelligent design (in the same breath as noting that those criticism have also been made by people not promoting intelligent design), he explicitly does not endorse the alternative explanation provided by intelligent design (and does also explicitly point to intelligent design as being motivated by religion.) So, it's beyond ludicrous to cite Nagel as not only a supporter of ID but support for the idea that ID is independent of religion.

Nagel’s also a philosopher best known for advancing the perspective that materialist objectivity is a limiting perspective, that is, he is a skeptic of the framework in which science operates. So he's even a worse example to use to make the argument (even if he supported ID, which he doesn't) that ID is within the domain of science.


Mind and cosmos is one long argument about why we need some sort of teleological principle to explain our reality. He definitely comes across as an ID proponent in that book. Maybe I missed something...

For reference, here is an article Nagel wrote explaining the core of his book. https://opinionator.blogs.nytimes.com/2013/08/18/the-core-of...

"This means that the scientific outlook, if it aspires to a more complete understanding of nature, must expand to include theories capable of explaining the appearance in the universe of mental phenomena and the subjective points of view in which they occur – theories of a different type from any we have seen so far."

That is totally ID in a nutshell. One may then go on to make theological inferences, or not, as Nagel does.

In which case, perhaps he thinks the current paradigm of science as methodological naturalism is lacking. This is the same perspective that ID promotes. If correct, then Nagel and ID are on the side of science.

At any rate, I propose the relationship between ID and religion is not quite as you believe it to be. Happy to discuss the topic further if you are interested.


I totally agree. Intelligent design is about doing the research and good science, not 'god of the gaps'. The only assumption in the field is that detecting intelligent design is possible. If design detection can be done for the recent past, then design detection can be done for the distant past, as well.


If someone with deep pockets may be liable, there will be a well funded effort to debunk this.


You mean like the government of China?


...or a well funded PR campaign to assign blame to somebody else.

Seriously, this particular mutation of unknown bat virus + HIV is predicted in film. I recommend to watch it: it's very scientific, and has almost no action.
