Nature Hurts My Brain

I read quite a bit of scientific material. Not the deep research papers; those days are long gone and my knowledge is too out of date to follow along with immensely detailed analyses of ever more intricate experiments. What I do read is the commentary for the intelligent layman: the specialist science journalism in, for example, New Scientist, Science, Scientific American, Quanta, and various other places elsewhere online.

I don’t read everything – there isn’t time, and anyway there are subjects like climate change, extra-terrestrial life and artificial intelligence which bore me rigid.
[No I didn’t say they aren’t important, or don’t exist; I just said they’re not things I can enthuse over.]

The more I read, the more incredulous I become that anything in the living world works at all – let alone that it could have evolved from nothing, however long the timescales involved.

Apart from the way in which the SARS-CoV-2 virus seems to work, what brought this home to me most recently was and article in The Scientist about left-handed DNA. You see the normal DNA which makes up all our genes has a helical structure which twists in a right-handed direction. And the way that works is gobsmacking enough.

But DNA can twist the other way (left-handed) to form Z-DNA. This has been known for some time, but it is now thought it may have a role in cancer and autoimmune diseases. Even more bizarre is that short sections of normal DNA can flip to Z-DNA and this obviously has a major control on how the whole of the transcription process (which turns DNA code into proteins) works (or doesn’t work) – and that may be important for the prevention of autoimmune diseases or the growth of cancer.

It is fiendishly complex, and yet only one tiny piece in the corner of the jigsaw puzzle which is eukaryote metabolism. I remember when I was a postgrad student (45 years ago) having a huge A1 (maybe bigger) poster full of the (then known) metabolic pathways in tiny print. It was gobsmacking, and totally unmemorable, then and has since been shown to be many times more complex.

The way the living world works – from grass, to rabbit, to fox, and to you yourself – is absolutely incomprehensible and incredible. I can quite see why some people cannot believe in evolution and insist that the whole must be divine design. I don’t agree with that, but that makes it no less brain-addling.

Much More than Environmental Reform

My friend Ivan had recety started a new blog, Restored World. In Ivan’s words:

I have created this website to share my thoughts and reflections on how we might respond in new ways to the needs of our damaged, ailing world. What has led me to speak out here is my belief that our current way of thinking and doing things is not only inappropriate but continues to harm us.

It is clear from our collective struggles to even begin to address the climate emergency, the mass species extinction, increasing inequality, or other challenges such as the present spread of the Covid-19 pandemic, that we appear trapped … within an outdated mode of thinking that determines our functioning, a mode no longer appropriate to the immense challenges we face in the present global crisis.

We collectively all need renewal, myself included, if the world in which we live is to be restored. My hope is that this website, which is a personal account of my search for that renewal, can be a small contribution to our collective effort in imagining how we will restore our world.

Although Ivan and I are coming at the problem from different perspectives (and this blog is more wide-ranging) we seem to be singing from the same hymn sheet. Ivan is a thinker, and as a professional writer is much more eloquent in expressing his views than am I.

One thing reading Ivan’s thoughts has done is to goad me into finishing something I started long ago: encapsulating the way I see the complexity of environmental reform in a diagram.

Environmental Reform Diagram

Environmental reform isn’t easy. As the above diagram shows it involves a whole interdependent network of actions and effects which revolve around three core necessities:

  • Reform of Agriculture and Fisheries
  • Reform of Natural Resource Usage
  • Reform of Energy Production.

There are a number of obvious entry points to the network, although starting anywhere one can is better than not starting at all.

What this doesn’t show is the necessity to reduce our reliance on product, and reform both our dominant capitalist hegemony and our broken political system. Each will be another complex network and connecting these reform networks will be yet another level of interdependent network – and I haven’t thought about any of that, yet! We could start on this anywhere, in any of the networks, and hopefully actions in one place will flow through into the other networks.

None of this is easy. But we have to start somewhere and hopefully the current Coronavirus pandemic will trigger the paradigm shift we need, which will flow over into real action on climate change and global reform.

Wish us luck!

Coronavirus: Attitudes to Panic

This post has originated in all the fuss surrounding the Coronavirus situation. In it I’m not interested in the science of how the Coronavirus works, or how it is being treated. I’m more interested in our reactions and the way we (individually and collectively) are approaching the problem.

The post is constructed around quotes from four comment articles [1-4] (referenced below) which have appeared in the last few days.

What’s interesting to me, from a rational standpoint, is the psychology and attitudes behind what is happening.

In the new coronavirus, we see a world that is more connected than ever by international travel, but that has also succumbed to growing isolationism and xenophobia. We see a time when scientific research and the demand for news, the spread of misinformation and the spread of a virus, all happen at a relentless, blistering pace. [4]

For example: The number of people travelling by plane every year has more than doubled since SARS first emerged, in 2003 [4] and we now have 24 hour rolling news both online and on TV.

On top of that

People are often optimistic about risks [called] “optimism bias”; people may think they can control their own exposure to diseases, that they don’t need a vaccine because they aren’t susceptible to flu, or that they won’t transmit their cold to others. [1]

It’s entirely normal that there are still many uncertainties [4]. We don’t yet know enough to be completely certain about the risks of COVID-19 … no one really knows how bad COVID-19 is, and how much damage it could eventually lead to [3].

For instance: How transmissible is the virus? Once infected, how much time passes before people show symptoms, and how likely are they to die? Which people are most at risk? [4].

It appears that on average, infected people spread the virus to two or three others [4]. This the Basic Reproduction Number (what epidemiologists call R0). It is about the same as that for flu, but way lower than for measles which has an R0 of 12-18 [5].

Current data suggests that COVID-19 kills around 2% (the Case Fatality Rate) of those infected [3] (although expect this number to change). However flu with a Case Fatality Rate of 0.1% kills more people [3] (presumably because although it is more widespread, we have a vaccine).

Even the normally cautious epidemiologists don’t know the answers. Harvard epidemiology professor Marc Lipsitch [says] “I think the likely outcome is that it will ultimately not be containable” [2].

In fact

Lipsitch predicts that within the coming year, some 40 to 70 percent of people around the world will be infected with the virus that causes COVID-19. But … this does not mean that all will have severe illnesses. “It’s likely that many will have mild disease, or may be asymptomatic”. [2]

That doesn’t sound good, so no wonder the uncertainties that academics are used to dealing with, about fatality rates or transmissibility, are stoking fear [4] because when we’re uncertain about something, we often rely upon our feelings and prior experiences in place of information. Surgical face masks offer the sense, however illusory, of protection [1].

Indeed

According to experts, the value of surgical masks depends entirely on the context in which they’re used: a surgical mask won’t work unless it’s worn consistently and properly. If worn incorrectly, their utility quickly plummets … Though face masks may provide the feeling of security, masks are most valuable in situations where they are necessary – such as among front-line health workers … We touch our faces, noses and eyes many times a day, making it difficult to completely avoid contact with infection. [1]

[If you want more on face-mask efficacy, see my post “Coronavirus and Face Masks” of a few days ago.]

While

researchers can share data and refine ideas faster than ever … they’re doing so in full view of a concerned citizenry … [and] … preliminary data that might once have run the gantlet of peer review before being published can now be downloaded by anyone, sparking misinterpretations and conspiracy theories. [4]

A climate of uncertainty can cause misinformation to flourish [1] and create fertile ground for mixed messages and inconsistency, which in itself can breed mistrust and fear [3]. And as we all know false reports readily cascade through channels that amplify extreme messages over accurate ones … Hoaxes and half-truths are huge problems during epidemics [4].

But of course we’re often required to make decisions based on having incomplete information [3]. I would actually go further: we never have all the information we need to make the decision; all we can do is to make the best decision we can at the time with the (limited) information we have.

This is why clear messaging from trusted sources, and guidance on what to do and how to do it, is essential during a pandemic [1]. Especially communicate often, communicate what is and isn’t known clearly, and provide simple action items for individuals to take … like hand-washing [and] acknowledge that [all of this] may change quickly [3].

However with public health that’s not easy. The risks of sending the “wrong” message can have devastating consequences – unnecessary anxiety on the one hand … and thousands of unnecessary deaths on the other [3]. And confused citizens might forgo sensible measures such as hand washing in favour of inefficient ones like panicked mask buying [4].

What’s perhaps worse is that border screenings and travel bans have historically proved ineffective and inefficient at controlling diseases. If anything, they can make matters worse. People will find a way to get where they want to go [4]. For example, although the Iran/Afghanistan border has been closed, some 3000 people cross that border illegally every day [6].

What’s more

bans can also break the fragile bonds of international trust … If countries know that they’ll be cut off during an epidemic … they may be less likely to report future outbreaks, leading to costly delays. [4]
Waiting too long to sound the alarm can be disastrous. [3]

As with many things this leaves us with a spectrum of possible reaction and attitude.

On the rational end, we must ask ourselves about … the effectiveness of [any] solution … [and how individuals can use that] solution effectively. On the emotional end, we ask ourselves about … how severe might it be if we … were infected [and] how likely we might contract it. [3]

A lot of the expert discussion (or at least discussion quoting experts) in the media has been at the rational end about the effectiveness of various actions, while I suspect a majority of individuals are inclined to work more towards the emotional end of the spectrum – often because they’re not presented with clear, concise, factual information; whether deliberately by the less reputable press and politicians, by omission, or because it is just packaged in a way they can’t understand.

At the end of the day we probably have to move individuals quite a long way (probably further than is possible) towards the rational side, while at the same time ensuring that the experts are doing as much as possible to make the right solutions effective and have some understanding to allow them to meet the individuals part way. That’s probably a circle that can never be made fully square. Nevertheless the experts have to work their socks off to square the circle as best they can, and take the people with them in supporting their solutions. And that ain’t ever going to be easy.

Fukushima’s Tritium

The Fukushima nuclear site is now overflowing with contaminated water (from cooling the remaining fuel cores to prevent further meltdown) which is being stored in huge tanks. Like they have almost 1.2 million tonnes of water from which the major radioactive contaminants have been removed (they say). And they’ve almost run out of space for more tanks.

However the stored water is still contaminated with tritium (3H), a rare radioactive isotope of hydrogen with a nucleus containing one proton and two neutrons, and a half-life of 12.32 years. Although radioactive, tritium is generally considered safe, at least externally (one common use is in luminous watches and displays).

But this presents a problem, because to even reduce the tritium level by 90% through natural decay will, I guestimate, take in the region of 40 years (something over 3 half-lives). Would that level of reduction be enough? I don’t know; I’ve not seen the data.

Extracting the tritium from the water is technically very difficult and there is no industrial-scale process available to do it.

So to solve their storage problem Tokyo Electric (Tepco) want dump the contaminated water into the Pacific Ocean. The alternative contending suggestion is to allow the water to evaporate into the atmosphere (taking the tritium with it); but this has been rejected.

Now I see the logic of dumping the water into the ocean. There is already a (low) level of tritium in seawater anyway; and most nuclear facilities use either seawater or river-water as a coolant, with the waste water flowing back into the river/ocean in real-time with low levels of contaminants (mostly tritium).

My reaction to this as a scientist is that dumping the water into the sea, over a period of years, and maybe from several sites separated by a distance, is likely the best solution; and not a solution that would, I think, worry me if it were “in my backyard”. On the other hand I do quite see, from an environmental viewpoint, why local people and nearby countries don’t like the idea.

It’s just a pity there isn’t an industrial-scale extraction process, because the tritium would be extremely valuable, even if it amounted to just a handful of grams. For one, the JET European Torus experimental nuclear fusion reactor is planning a run for late this year, and for that they need a few grams of tritium, which costs around $30,000 a gram. Surely there must be a way?
