kary mullis, pcr, & covid tests - BioBlog

May 19, 2021

You’ve probably come across the name Kary Mullis recently, via social media. He’s best remembered for his invention (along with a team of other researchers) of the Polymerase Chain Reaction, or PCR for short (and for many biology students was probably immortalised in their memories via this earworm of an advertisement¹). This turned out to be a very powerful tool, often used in combination with genome sequencing, for medical researchers and other scientists. It’s been used for everything from determining paternity, forensic testing, ancient DNA (aDNA) work on human ancestors (and other species), obtaining enough DNA from a specific gene for research on genetic disorders, and more besides, including identifying the presence of SARS-Cov-2. If you’d like to learn more about the technique, there’s a good explanation here, and this teachers might find … Read More

covid-19 infection and how the spike protein is involved in doing harm - BioBlog

May 05, 2021

  Just this morning a journalist sent me a link to a press release about a new paper looking at how SARS-Cov-2 affects the vascular system, & asked to comment on it for a article. If you’d like to read the actual paper you can find it here, but be aware that it does get complex in places (it’s an in vivo study using hamsters as the host organism). I found it really interesting  – as the researchers say, it “could open the door for new research into more effective therapies.” The spike proteins are the structures projecting from the virus, and they’re what the immune system learns to recognise (and then attack). SARS-Cov-2 uses them to connect to host cells, before its genetic material is moved into the cell & used to force the cell to make … Read More

on Plan B’s support for an anti-vaccine court case - BioBlog

Apr 26, 2021

Some of my readers may be aware that Nelson lawyer Sue Grey is taking a case to the NZ High Court in an attempt to stop the roll-out of the Pfizer vaccine. I don’t agree with her stance, but she has every right to do this. However, I was more than a little surprised to see that one of the academics promoting “Plan B” as an alternative to the government’s current means of controlling the spread of SARS-Cov-2 in this country has provided an affidavit supporting this action. You can find this document on the public website, as “Vaccine_Court Documents – Our land Our Water Our bodies”. I haven’t linked directly because my antiviral software didn’t like the page. (I find this … amusing.) Dr Thornley’s PhD research was into the statistical prediction of cardiovascular disease, and … Read More

sam bailey on isolating viruses, and why she is wrong - BioBlog

Apr 19, 2021

Recently I was told I needed to go to the Youtube channel of Dr Sam BaileyA and watch one of her videosB. So I did. This particular video is called The Truth About Virus Isolation, and yes it’s on Youtube, and no I’m not linking directly because I refuse to link to such a misleading channel. It’s ostensibly about the (lack of) isolation of the SARS-Cov-2 virus. Given that there have been a lot of papers published on this very topic, one might expect a discussion of what Bailey sees as their flaws – especially given her lead-in claim that “the scientific literature is a mess” – and at the very least reference to some of them. One would be mistaken. There is, however, a certain amount of shadeC: “I’m not sure if many virologists and scientists are aware of … Read More

why it’s important to check sources - BioBlog

Apr 17, 2021

While checking my spam folder (before yeeting the contents permanently) I noticed that I’d been sent a bunch of email ‘newsletters’ from the group “Voices for Freedom.” Out of interest I opened one, just in case the contents were worth a post or two – & indeed they were. The writers of the newsletter state that “And we take it further: we’re about sound science” and then a little further down the page claims “that there’s striking evidence that SARS-CoV-2 was around from at least 12 March 2019.(How do we know? Yes, we read the papers that experts write.)” They are, however, being a little disingenuous here. The link goes, not to a paper published in a journal, but to a pre-press server. I’ve highlighted the relevant bits from the top of the document. In … Read More

so much misinformation on a page supposedly about health - BioBlog

Apr 15, 2021

It’s always something of a shock to come across a page run by a health-focused business that contains substantial misinformation. This one left me gobsmacked, given the sheer number of statements that are demonstrably untrue. And while a fair bit of the content is prefaced by the statement that it’s the personal opinion of one individual, the fact that it’s carried prominently on the business’s webpage means that the business appears to support those views. The Covid-19 vaccines offered in NZ from this moment are no [sic] vaccines but a high risk first ever trial on humans of a GMO (gene modification) therapy. Just, no. The Pfizer BioNTech product is a vaccine: it stimulates an immune response to a pathogen (or more correctly, to an antigen from that pathogen) without your being exposed to the actual disease-causing organism. The … Read More

we haven’t taught critical thinking particularly well - BioBlog

Apr 14, 2021

  Yesterday I got told to “do some research” &, by extension, to think critically. The biologist in me cringed a little when I read it (and not because of the advice about doing research). Biology teachers I know suggested that perhaps everyone should take the NCEA standard that lets students learn about the basic genetics that this commenter got so very, very wrong. But personally I think that’s not really the issue, and it isn’t the fix either. This is because the relevant genetics content isn’t taught until students hit year 12, and sadly a lot of students (up to 60%, by some estimates) have decided not to continue with the sciences beyond year 10. That in itself is a problem that needs addressing, but it’s not my focus for this post. To me there are … Read More

evidence vs spin - BioBlog

Apr 14, 2021

A friend of mine pointed me in the direction of this blog post by New Zealand’s “Plan B” group. While initially this group opposed the government’s use of lockdowns to manage covid19 outbreaks in this country, they seem to have since moved on to opposing the rollout of vaccines against SARS-Cov-2. And, while they claim to be “injecting evidence into the vaccine spin,” on balance the spin is on their part¹. Why do I say this? Let me count the ways. The authors of this Plan B post, Simon Thornley & Gerhard Sundborn, describe the Pfizer/BioNTech vaccine as the least tested vaccine in living memory Least tested? The Phase III randomised controlled trial (RCT) for this vaccine involved 43,000 people – more participants than in pretty much any other vaccine RCT. For example, this large trial of Gardasil … Read More

there’s a word for this sort of misinformation about vaccines - BioBlog

Apr 10, 2021

A friend found a concerning FB post (see below – this is a public post & so I have not redacted the name) & – as you do – immediately queried it with Southern Cross Life & Health Insurance as well as sending the screenshot to me¹. We both read the relevant policies & exclusions and were pretty sure the post was incorrect. (My friend said he was blown away by the number of commenters who clearly hadn’t bothered to do even a rudimentary fact-checking exercise.) Here’s what SCLHI has to say on the issue of insurance cover & getting a vaccine against covid-19. I’ve used bold font to highlight the key comment, but there is so much wrong in what’s being claimed in that FB post. Southern Cross follows the recommendations of the Ministry of Health and MedSafe … Read More

“doing my own research” & the scientific method - BioBlog

Apr 07, 2021

This evening I was engaging in polite conversation (well, I was polite, anyway) on an RNZ Facebook post about – you guessed it! – the covid19 vaccination program. One of those present offered up a link to a blog post by Joseph Mercola to support a claim he was making about the vaccines. When I pointed out that Mercola is an osteopath, who makes a lot of money from selling products that included fake cures for covid19 (he got an FDA warning for that), my interlocutor said that the source was fine because it was “with references to verify what he says. You know, the scientific method.” To me, this highlights a key problem with many of those who claim to have “done their own research” or tell me to do mine. They don’t really know … Read More
