Homeopath, Ebola and New Zealand – a follow-up Grant Jacobs Nov 23

5 Comments

About three weeks ago I wrote in a comment following a post about a New Zealand member of Parliament supporting homeopathy to treat Ebola:

Also, it would be interesting to see if governments (internationally) will step up and condemn these homeopaths that aim to push their remedies on Ebola patients, in a similar way that governments condemn those that join Islamic militant groups or do similar counterproductive activities. I suspect they’ll simply say nothing despite the obvious trouble this may cause. (See the Guardian article for some background on this. The Homeopathy Without Borders group also took some members to Haiti after the earthquake, aiming the treat cholera…)

I’m learning belatedly and second-hand (or third-hand…) that the World Health Organisation has blocked homeopaths from offering their remedies in Liberia. These look to be members of another homeopathy group, the Liga Medicorum Homeopathica Internationalis.

The writer of that blog is an oncologist writing under a pseudonym. (As he points out himself from time to time, it’s not hard to find out who he is.) He takes his lead from a Daily Mail piece that, to be very polite, gives the homeopathy group too much leeway and in his article he expresses shame that some of these homeopaths were physicians.

Those interested should read ‘Orac’s take on this; I would only end up repeating points he’s already made. (It’s also not as long as some of his missives!)

The Daily Mail is often known to the science communication community as the Daily Fail for it’s habit of regularly producing articles with spectacularly wrong science.* For example, in that article they quote this straight-out false claim by Dr Lindemann (Marenostrum private natural therapies clinic, Calle Fontanella, Barcelona), but make no effort to check or challenge it -

‘There is not yet one specific medicine widely available for the treatment of Ebola but there are homeopathic remedies that have been proven successful in treating other epidemics such as cholera.’

Simply not true. (Similarly you’ll see a reference to research on “various epidemics including Yellow fever”.)

Good governance, democracy and investment in science Grant Jacobs Aug 28

1 Comment

From what others have written here at sciblogs most readers will know that we have elections on in New Zealand soon.

While reading the newspaper last weekend I encountered an opinion piece by political commenter Colin James that includes commentary on investing in science that readers might be interested in.

His essay opens by talking about democracy,* governance and good longer-term policy, and closes on the same topic. Sandwiched in between, the central portion of the essay offers strong investment in science as an example of properly supporting longer-term policy that is good for the nation as opposed to short-term electioneering,

Good government has both short-term and long-term perspectives. Durable, long-term policies are the pillars of government. Longer-lived governments maintain those pillars (Bill English is this lot’s main maintenance man). But election campaigners often divert into the short term.

So the campaign will pay little attention to investment in science.

Ministers in recent governments of all stripes have kept scientists on short rations. The Key government has spent more energy restructuring institutions than money for good science.

Comments welcome, of course. What do you think is good science policy?

Gene editing and GMOs in NZ, part two – is the law out of date? Grant Jacobs Jun 02

10 Comments

(If you’re not a biologist, you may prefer to start with part one. There’s also a third part.)

Are the GMO-related clauses of the Hazardous Substances and New Organisms (HSNO) Act 1996 out of date? Perhaps it’s time to start working on a replacement.

Recently a legal ruling in New Zealand overturned a previous opinion that using gene editing to create variants would not create genetically-modified organisms (GMOs). The key documents are gathered at the EPA website page for that query.

In part one, I offered a non-scientist’s introduction to what is intended with the type work being considered. I’ve since spent more time browsing the Act and the ruling than is healthy for someone who is not a lawyer. Here I’d like to offer some initial thoughts from this reading.

The HSNO Act (1996) also deals with hazardous chemicals. For simplicity, when I write ‘the Act’ below, I mean the portion of the Act referring to GMOs not the whole HSNO Act.

In a nutshell

The court noted difficulties in interpreting the Act. The court was very polite and modest about the difficulties it encountered: my reading suggests these difficulties run deeper and indicate the Act is not up to it’s task.

My opinion is that Act is out of date in fundamental ways. It will also expire on one of it’s founding premises at some time. Thus it would seem an opportune time to work towards what would follow the current Act. (To my reading the Act is time-limited, in that it uses a premise that once a class of techniques have stood the test of time organisms made using them are exempted from consideration; in time the techniques that create GMOs themselves will have stood this ‘test of time’ and be exempted, closing the Act. Consistent with this, a replacement for the Act would not be GMO-specific, but sit within food safety in general.)

On the ruling

Given the problems with the Act the court ruling noted, I was left wondering if a call to make no ruling could not have been made. I believe the issues run deeper than those noted in the ruling (see below).

I found the approach that the advisory experts were used was unexpected. This will reflect my not being familiar with law practices, but it left me wondering if this was the best way to resolve interpretation of an Act. In addition, I feel more comfortable with advisory experts drawn from overseas and independently of the parties involved.

On the Act

The process to add new techniques to those that are considered exempt from GMO status seems (to this non-lawyer) to be ill-defined and problematic. There appears to be no explicit provision in the Act for new techniques that will arise. (The current ruling was caught out on this.) It feels as if a constructive mechanism to add new techniques is needed.

The Act was written at a time when testing if a technique created unexpected genetic changes was challenging and seems to reflect this in it’s design. This has changed, and will continue to change. My feeling is that this leaves the Act out of date in a fundamental way.

One premise in drafting the current Act is that organisms derived from classes of techniques that have stood the test of time are considered acceptable. This means makes Act is self-limiting in time: once GMOs have been around a suitable length of time the techniques that make GMOs as a class must also be considered acceptable. Given GMOs have been around approximately 20 years now, it would seem prudent to start work towards a more appropriate longer-term solution fitting them within food safety in general rather than as a special case.

Finally, and to be fairly brutal about it, parts of the argument used in the Act look ill-formed, possibly even fallacious. This is not helped by that it’s not clear precisely what the argument is, as it’s not made explicit; the court noted similar difficulties. Perhaps symptomatically, some labels and terms are not used in a self-consistent way (to this reader), confusing different positions and at odds with what they might ordinarily mean.

Sir Joseph Bank’s journal and account of New Zealand Grant Jacobs May 25

No Comments

Readers interested in historic scientific voyages and New Zealand history might like to know that Sir Joseph Bank’s journals of 25 August 1768 — 12 July 1771 aboard the HMS Endeavour under the command of Lieutenant James Cook are available on line from the University of Sydney Australia Digital Collections website.

This voyage observed the Transit of Venus (3 June 1769) and undertook geographical and natural history observation (including a search for the southern continent). According to the notes the natural history observation aspect to the voyage was an innovation “inspired, financed and directed by the 25 year old Joseph Banks.”

These journals include accounts of several islands, including a long account of New Zealand from their circumnavigation in 1770.

You can view the journal either as a web page or a PDF file. I find the latter more readable, but I wish they’d put the many-pages long series contents as an appendix rather than before to the body text. After reading the introduction, skip to page 26!

Homeopathy Awareness Week: how do you approve a course for something known not to work? Grant Jacobs Apr 15

13 Comments

Homeopathy[1] uses solutions diluted until the active ingredients are no longer present—water basically[2]—to treat illnesses.[3]

Poison-ivy-homeopathic-remedyThe premise of homeopathy is so absurd, it opens itself to parody.[4]

More seriously, homeopathy has been examined and found to be ineffective with several formal reports saying so. Fellow blogger Siouxsie mentions one such report from the Australian National Health and Medical Research Council. Similarly, the British House of Commons Science and Technology Committee’s report Evidence Check 2: Homeopathy gave a very firm “no” to homeopathy.

Coming forward and saying that homeopathy is ‘bunk’ isn’t a new development. Homeopathy has long been considered worthless. Take for example Oliver Holmes’ words this vectorial speech to medical students in 1871:[5]

  Some of you will probably be more or less troubled by the pretensions of that parody of mediaeval theology which finds its dogma of hereditary depravity in the doctrine of psora [homeopathy], its miracle of transubstantiation in the mystery of its triturations and dilutions, its church in the people who have mistaken their century, and its priests in those who have mistaken their calling. You can do little with persons who are disposed to accept these curious medical superstitions. The saturation-point of individual minds with reference to evidence, and especially medical evidence, differs, and must always continue to differ, very widely. There are those whose minds are satisfied with the decillionth dilution of a scientific proof. No wonder they believe in the efficacy of a similar attenuation of bryony or pulsatilla. You have no fulcrum you can rest upon to lift an error out of such minds as these, often highly endowed with knowledge and talent, sometimes with genius, but commonly richer in the imaginative than the observing and reasoning faculties.

[Oliver Wendell Holmes, Medical Essays. From The Young Practitioner, A Valedictory Address delivered to the Graduating Class of the Bellevue Hospital College, March 2, 1871.]

Modern statements that homeopathy is no better than placebo offerings are backed by studies. You might think that this would lead to no standards bodies approving courses teaching it.

However, in New Zealand the NZ Qualifications Authority (NZQA) approves courses in homeopathy.[6]

A question, then. How do you approve a course in something that is known not to work? Known not to have therapeutic value beyond a placebo effect.

If you search the NZQA website for ‘homeopathy’ you’ll be offered five pages among them listing courses and institutes that they have approved. As one example, they approved a ‘Certificate in Acute Prescribing with Homeopathy’. You don’t have to be a medical practitioner to realise ‘acute prescribing’ of homeopathic remedies makes little sense.

Elsewhere I have argued that homeopathic remedies should not be present in pharmacies. Should courses in homeopathy not be formally approved by NZQA?

You’re welcome to offer your thoughts in the comments below.

My feeling is that veneers of respectability and soundness ought to not to be given to practices like this as it may give consumers the misleading impression that the treatments ‘must’ have some merit if a formal accrediting agency has put their weight behind the courses teaching it.

Footnotes

Thanks to Alison Campbell for bringing the NZQA approval of homeopathy courses to my attention.

1. Or homoeopathy, but I prefer the simpler and more common form. (I confess, also, that for a while I found myself occasionally mistyping homeopathetic.)

2. Some seem to use alcohol as the solvent, in which case you might just as well take a nip of your favourite (strong) alcoholic drink.

3. The mixtures are, apparently, shaken between each serial dilution. My recollection is that this originated from a variant of his remedy that Samuel Hahnemann, the ‘inventor’ of homeopathy, introduced to help sell his remedy where a strong brand of Christianity appealed to faith healing. This variant was to whack the mixture against a bible after each dilution so that the power of the good book might enter the remedy. (Or so the sales pitch went.) The (few!) homeopath websites I have viewed made no mention of a bible but do mention shaking the mixture.

4. There are many other examples; this one isn’t by any means the best but I hope it gives readers the general idea.

5. I like the allusion to Archimedes, although I suppose you could say it really wants ‘nor a lever long enough’ added to it, rather than (just) the size of the fulcrum.

6. We could also look at other things NZQA approve such as courses in such as naturopathy and so on, but let’s stick to homeopathy for now. They have a section ‘Complementary Therapies’.

Any New Zealand schools want to help judge the Flame Challenge? Grant Jacobs Dec 13

No Comments

(Crowd-sourcing how best to let NZ schools join in the judging of the Flame Challenge.)

The Flame challenge is an international competition that challenges scientists to explain to 11 year-old students a question. The results are judged by children. (There is more on the Flame Challenge in my previous post.)

This year’s question is ‘What is colour?’ Explanations are in two categories, written or visual. The visual entries include short videos.

The question was drawn from more than 800 suggestions from around the world. Last year there were over 20,000 student judges.

I have been asked by the Alan Alda Center for Communicating Science who run the Flame Challenge for suggestions how New Zealand schools might get involved in judging — apparently no New Zealand schools have been involved in judging the entries before.

AgResearch moving house – let’s have the full picture Grant Jacobs Aug 01

11 Comments

Further details of AgResearch’s plans to move (large) parts of its operation to create ‘hubs’ were released yesterday. As I had suspected earlier this involves substantially reducing operations in some parts of the country.

One hub will be created at Lincoln, which I introduced earlier; the Grasslands campus at Palmerston North is also to be expanded. I won’t speak much of the North Island part of this as I’m less familiar with the locations and science done there. (Fellow blogger Ken Perrott has written of the downscaling of the Ruakura campus.)

One of my concerns after the initial announcement of the hubs several months ago was that the disruptions and negatives of this would cause were glossed over in the initial announcement in a ‘positive spin’ exercise.

As Crown Research Institutes (CRIs), they are effectively owned by the public and I personally would have liked to see more complete communication of all aspects, not just a sales pitch, given the public monies involved.

In particular, I have been unable locate a document laying out the overall plan with an examination of the key issues and the estimated costs and benefits. I would like to have seen a publicly-released case for this before it was decided, but it seems that these actions have been decided at a high level as, for all practical purposes, a fait accompli.

Terry Speed on Epigenetics Grant Jacobs Jun 21

3 Comments

Epigenetics is an increasingly used jazz word, and I don’t just mean by scientists. You can see it in magazine articles, marketing spiels, and so on.*

It’s touted as some kind of new, special genetics.

Epigenetics itself isn’t new. It’s basically the business of how our cells express their genetics, how the characteristics of a particular cell type (or organ or animal) are realised from it’s genes.

Some things we’re learning about epigenetics are new, however.

But you don’t have to hear these from me.** You can listen to Terry Speed’s public lecture on epigenetics, given during a particularly strong winter storm in New Zealand’s capital city, Wellington. (Given that, we ought to praise those who attended too.)
