Male Circumcision

I’ve written before about my belief that male circumcision should be outlawed (unless really medically essential) — see inter alia here and here.
Well this peer reviewed paper looks like another damn good reason not to circumcise boys.
Morten Frisch & Jacob Simonsen, “Ritual circumcision and risk of autism spectrum disorder in 0- to 9-year-old boys: national cohort study in Denmark”, J R Soc Med OnlineFirst, 8 January 2015.

Abstract
Objective: Based on converging observations in animal, clinical and ecological studies, we hypothesised a possible impact of ritual circumcision on the subsequent risk of autism spectrum disorder (ASD) in young boys …
Participants: A total of 342,877 boys born between 1994 and 2003 and followed in the age span 0–9 years between 1994 and 2013.
Main outcome measures: Information about cohort members’ ritual circumcisions, confounders and ASD outcomes, as well as two supplementary outcomes, hyperkinetic disorder and asthma, was obtained from national registers. Hazard ratios (HRs) with 95% confidence intervals (CIs) associated with foreskin status were obtained using Cox proportional hazards regression analyses.
Results: With a total of 4986 ASD cases, our study showed that regardless of cultural background circumcised boys were more likely than intact boys to develop ASD before age 10 years … Risk was particularly high for infantile autism before age five years … Circumcised boys in non-Muslim families were also more likely to develop hyperkinetic disorder … Associations with asthma were consistently inconspicuous …
Conclusions: We confirmed our hypothesis that boys who undergo ritual circumcision may run a greater risk of developing ASD. This finding, and the unexpected observation of an increased risk of hyperactivity disorder among circumcised boys in non-Muslim families, need attention, particularly because data limitations most likely rendered our HR estimates conservative. Considering the widespread practice of non-therapeutic circumcision in infancy and childhood around the world, confirmatory studies should be given priority.

On Depression — V

This is number five in my series of articles on depression — my depression. They are written from a very personal perspective; they are my views of how I see things working and what it feels like on the inside. Your views and experiences may be vastly different. My views and experiences are not necessarily backed by scientific evidence or current medical opinion. These articles are not medical advice or treatment pathways. If you think you have a problem then you should talk to your primary care physician.

Questions & Answer
In the course of writing these posts I’ve collected a small number of articles which throw some interesting lights on various aspects of depression. I’ve already mentioned some, but this post is to try to gather some of the others together.
The first is a quote from The Body Keeps the Score: Brain, mind, and body in the healing of trauma by Bessel van der Kolk

If your parents’ faces never lit up when they looked at you, it’s hard to know what it feels like to be loved and cherished.

Now that’s a fairly telling statement and if, like me, it fits your childhood then any wonder we get depressed.
This next is a link to a cartoon, about just how badly we treat the mentally ill (not just the depressed but I guess it happens to us more as our illness isn’t always so apparent). So what would it be like if physical illness were treated as we treat depression.
And now a short animated video which explains a little of the science behind depression but also highlights, perhaps, how little we really know.
Unfortunately research into depression struggles to attract funding in a way which would not be tolerated for, say, cancer. This Scientific American article demonstrates how important it is to change this especially now that useful technologies are becoming available. For those who don’t want to read the whole article here are a few key comments.

If the extent of human suffering were used to decide which diseases deserve the most medical attention, then depression would be near the top of the list.
[…]
[A]lthough depression is common, it is often ignored. Three-quarters of people with depression in the United Kingdom go undiagnosed or untreated — and even if the disorder is diagnosed, today’s medications will work well for only about half of those who seek help.
[…]
Research into depression … seems to have floundered.
[…]
Although … extra money would have solved some challenges earlier, the technology needed to crack others — by probing the brain and analysing its circuits, for example — is only now emerging.
[…]
[A]nother major factor is the long-standing stigma associated with depression. Many people still do not acknowledge that it is a legitimate condition … A large proportion of people believe depression is just something that we all feel … They think you should pull your socks up and get back to work.

One thing which seems to be common to most depressives is sleep disruption in some form, whether that is a disrupted or inappropriate sleep pattern or just plain old insomnia. But there may be some distant hope as scientists seem to be homing in on disrupted circadian rhythms being the underlying cause.

Disrupted sleep is so commonly a symptom of depression that some of the first things doctors look for in diagnosing depression are insomnia and excessive sleeping … scientists have observed for the first time a dysfunctional body clock in the brains of people with depression.
[…]
People with major depression … show disrupted circadian rhythms across brain regions.
[…]
[G]ene activity in the brains of depressed people failed to follow healthy 24-hour cycles. They seem to have the sleep cycle both shifted and disrupted.

The article goes on to explain how looking at the brains of dead but non-depressed people the scientists could pinpoint the time of death from how various genes were switched on or off. This was impossible with depressed subjects whose clocks were both shifted and disrupted. It isn’t simple as there are many genes involved, but variations in the gene expression could potentially cause all sorts of different sleep pattern disruptions.
Here are two more articles on sleep and depression. This first Sleep and Depression is a fairly simple explanation of the sleep disruption you may encounter and some pointers to what you can do to try to alleviate it. The second by David Nutt & Louise Paterson is an academic review from 2008 of what was then known; needless to say it contains lots of data.
Finally in this short round-up we must return to the question of body clocks, because another aspect is Season Affective Disorder (SAD) which affects many people during the darker winter months probably because we don’t get enough light to reset our clocks every morning. A very recent article by Katherine Hobson on Nautilus summarises some of what is known about high intensity light therapy to treat not just SAD but potentially other disorders too.

Light therapy has become standard for treating seasonal depression … light has a benevolent influence on mood during the dark days of winter instinctively makes sense: As hazardous as sunbathing is, it certainly feels good … research into the circadian underpinnings of chronic depression, bipolar disorder, Alzheimer’s disease, and fatigue suggests that light could help these patients readjust too.
[…]
Exactly how light works isn’t known, but many researchers suspect that bright lights help SAD sufferers by regulating their sluggish circadian clocks.
[…]
[C]ircadian rhythms appear to be disturbed in non-seasonal maladies too, which means there is a potential for light therapy beyond SAD.
[…]
In general, bright light therapy is a low-risk and low-cost option for treatment … it may speed up patients’ responses to antidepressants.
[…]
[T]he elderly might be particularly susceptible to the benefits of light therapy because their light perception declines with age, which might be throwing their internal clocks out of sync.

While SAD is one of the factors in my depression — and I know I feel much better on bright sunny days — it is far from the only one and is not the most crippling. I have tried light therapy two or three times over the years and never had much success with it. But it doesn’t work on everyone: while it doesn’t work for me it might work for you.

On Depression — IV

This is the fourth in my series of articles on depression — my depression. They are written from a very personal perspective; they are my views of how I see things working and what it feels like on the inside. Your views and experiences may be vastly different. My views and experiences are not necessarily backed by scientific evidence or current medical opinion. These articles are not medical advice or treatment pathways. If you think you have a problem then you should talk to your primary care physician.

Questions & Answer
What causes your depression?
As I’ve tried to say in previous articles in this series, the cause of my depression is certainly multifactorial. I know I have a tendency to Seasonal Affective Disorder (SAD) and I am certainly worse during the winter months. I also know that I may have a genetic predisposition to depression. My father was depressive, although I think never treated for it. And by all accounts my father’s father also suffered from depression. In my grandfather’s case this was put down to Trench Fever from WWI and the depression shouldn’t be surprising given his experiences in WWI and that he was a struggling back-street corner grocer in the Depression. Clearly none of this would have helped my grandfather but I suspect, from the little I knew him in old age, that he would have suffered from depression regardless. But then all the men in my family (and I include myself) are dysfunctional.
Perhaps, to me, the most obvious cause of my depression is stress, change and far too much to do; so much that I can never hope to catch up. Yes, I know I take things on (although I am getting better at picking and choosing what I do) and I’m involved in various voluntary projects. But I can’t sit and do nothing! As I said in an earlier post, an acquaintance commented to me recently about his situation: “if I sat at home all day I’d go senile”.
Other things that add to the depression, although may not be direct causes, are financial security (will I run out of money in a few years time); lack of achievement (past and present); a lack of attention (although I’m a loner I do still need people); dieting, having to watch what I eat and drink; being ill. All of those make things worse.
What are the physical effects of your depression?
It’s sometimes hard to separate the physical from the mental, the depression is so pervasive. Basically I feel incapable of doing anything. Nothing is fun or enjoyable. Everything is too much effort; I don’t even want to get out of my chair and make a cup of tea; and it’s this lack of ability to get up and do which stops me doing all the things, like exercise, which I know I should do. It’s like someone has taken all the elastic out of the joints and brain. I’m usually headachy and irritable. I often feel weepy — which is usually a part of a mild panic attack about being able to do something. I’m not interested in anything; I don’t want to do anything — even hobbies; and I can’t concentrate. I frequently sleep badly, although I’m dead to the world in the mornings and can sleep fine all morning. In the last few years I’ve had a very low libido; something I never used to have a problem with. It is all too easy to eat too much (which I know I do) and drink too much alcohol (which I am able to control — I am nowhere near being an alcoholic but I know I could go that way).
You’re on antidepressants. Do they have any side effects?
Mercifully I seem to tolerate most drugs fairly well; I’m not someone who gets allergic reactions, nausea or many of the more regular side-effects of most drugs. I’m currently on a moderate dose of my antidepressant. In the past I have been on the maximum dose, but managed to reduce this a couple of years back. And I don’t want to go back on the maximum dose because then I do get some side effects. The two most noticeable things are due to the anticholinergic effect of antidepressants: they decrease gut motility, so one tends towards constipation; and they are extremely good at preventing (not just delay; prevent) orgasm (which is why I don’t want to go back on the higher dose).
The other thing about the antidepressant I’m currently on is that it is one of the worst for getting off. Over the years I’ve had several attempts at reducing them with the intention of changing drugs, but every time I’ve ended up with withdrawal symptoms. I’m currently trying again and I’m more hopeful this time.
What is the depression like on the inside?
At the moment I have half a cold. Apart from the slight sore throat and tickly cough this is how I feel almost permanently. At least some part of a headache. Stiff neck, which is probably the cause of the headache. Physically drained, as if someone has taken all the elastic bands out of my joints, and slightly achy. I just want to close my eyes, and maybe sleep. I feel as if I have a head full of cotton wool and it’s been used as a football. I cannot cope with thinking about doing anything; let alone actually doing anything and certainly nothing I have to concentrate on. Thinking is fuzzy because I can’t concentrate. Everything is an effort. All I really want to do is curl up under the duvet until it goes away.
This is very much like you feel after a bad bout of ‘flu; when you’re beginning to recover but can’t yet do anything. You’re totally debilitated and incapable. And everything is too much effort — mentally and physically. But with ‘flu this goes away after a day or two. With depression it doesn’t; it stays; day after day after day after day …
Sometimes I have to curl up under the duvet; and sometimes some part of it does go away. For a while.
Are you typical?
I’m not sure there is a typical depression or reaction to it; we’re all different, although as I’ve maybe shown there is a set of common themes.
I got another view recently from Charlie at Sex blog (of sorts) who wrote about her depression.

Anxiety is so much worse than depression, right? Depression is just, well, sadness. And I can handle sadness … Sadness can be fixed with chocolate and wine and hot baths and long walks and time alone. Sadness is like a prompt to take better care of yourself: to eat properly, to get some fresh air, some more sleep.

Yeah, right! Charlie is being somewhat tongue in cheek here. This isn’t full on clinical depression. It’s more like what I’ve termed Dynamic Depression. But then she goes on:

I sit and I feel this crashing sense of despair that things will always be this shit, so what’s the point? What’s the point of anti-depressants or therapy, when life isn’t going to improve? Why won’t everything just stop? Why can’t I just go to bed and stay there?
… … …
People don’t understand why depression is tiring … It’s tiring not only because everything seems so pointless, but also because I’m in constant battle with myself. I’m not this person who doesn’t have any determination to achieve stuff: I have a good degree, a good job, some fucking self-respect, for god’s sake … my ability to give a fuck about any of that stuff has totally gone. Except it hasn’t. I still do give a fuck about it and so I beat myself up: I’m doing a shit job at work, I’m not socialising enough, I’m a lazy cunt. And the more I think and act on those feelings the closer I circle to burn out.

That’s better. That’s pretty much how I feel a lot of the time.
How do you get out of that?
That’s the point. I don’t have a flying clue. If I did you wouldn’t be reading this.

This series may, or may not, be continued at a later date.

On Depression — III

This is the third in my series of articles on depression — my depression. They are written from a very personal perspective; they are my views of how I see things working and what it feels like on the inside. Your views and experiences may be vastly different. My views and experiences are not necessarily backed by scientific evidence or current medical opinion. These articles are not medical advice or treatment pathways. If you think you have a problem then you should talk to your primary care physician.

The medical profession generally characterise different types of depression by their causes and effects, and they may range from mild, through moderate to severe. (See, for instance, www.mentalhealth.org.uk/help-information/mental-health-a-z/D/depression/.)
However pragmatically, over the years, I’ve come to realise that there seem to be two types of depression, which I have never heard voiced by a clinician. I’ll call them Dynamic Depression and Static Depression on the basis of what appears to help alleviate them. I’m not in a position to work out if the symptoms and/or causes are different although I suspect Dynamic Depression is at the milder end of the spectrum.
Dynamic Depression
This is the type of depression which everyone thinks you have, and which is the subject of every self-help book (and a lot of counselling) that I’ve encountered. The “cure” (which is how I characterise these two types) goes along the lines of “put on some brass band music, have a cold shower, think how blessed you are with everything you have going for you, and just get on with life”. Yeah, right. That may work for some people; probably those with low-grade depression who have a short-term problem. This is out of the book of “tell it like I want it to be and it’ll be that way” management. It is a fallacy which does nothing but con the brain — though that may of itself be valuable for some. It doesn’t work for me; it never has; and it may be why I’ve never succeeded with talking therapies.
Static Depression
Many years ago I read an article by a couple of medics who had looked at a small number of patients hospitalised with depression. Unfortunately I didn’t keep the article and I cannot now trace it, but this was the gist … They found that if these patients were given the standard treatment of drugs and compulsory occupational therapy they didn’t get better and sometimes got worse. Further they observed that all the patients wanted to do was to sit in the corner. So the medics allowed them to sit in the corner. And they found that as long as the occupational therapy was there, and visible to the patients, then allowing the patients to sit and vegetate meant they eventually started to get better; they eventually came out and joined in the occupational therapy and started to recover. The medics’ hypothesis was that this was because these patients were suffering from too much stress and change in their lives and they needed a prolonged period of stability, on their own terms, to recover.
This is what my depression is like. It is (at least in part) triggered by stress, lots of expectation and a high level of change. Which, I suspect, is why the “dynamic” approach doesn’t work on me.
Fortunately it is now recognised that change, especially, is a major contributor to depression. And change is why our society has increasing rates of depression — society is always chasing after “faster, better, cheaper”; there is no stability and no respite. It is becoming a major mental health problem, and the solution is not to keep popping happy pills.

On Depression — II

This is the second in my series of articles on depression — my depression. They are written from a very personal perspective; they are my views of how I see things working and what it feels like on the inside. Your views and experiences may be vastly different. My views and experiences are not necessarily backed by scientific evidence or current medical opinion. These articles are not medical advice or treatment pathways. If you think you have a problem then you should talk to your primary care physician.

I was first diagnosed with depression back around 1980 — certainly some time in the two years after Noreen and I married. I have been on and off antidepressants ever since. And over the years I’ve tried just about every possible approach to managing the depression: drugs; psychiatry; counselling; CBT; giving in and curling up under the duvet.
Talking therapies don’t work on me and they never have; I know (and have likely tried) everything they try to suggest and I know already it doesn’t work. Such is the curse of being intelligent, questioning and experimental. The last thing I need is for some therapist to give me something more to do.
For the last couple of years I’ve been having monthly-ish hypnotherapy sessions and even this has not yet been very productive, although I remain hopeful; it feels closer to a solution than many previous attempts.
Looking back I have probably been depressed at least since my teenage years, maybe earlier, although no-one, including me, realised. It may all be tied up with being shy; a loner; and not having many friends.
The first real trigger I can remember was at the start of my second year at university (so over 40 years ago) when my girlfriend of over 2 years and I broke up (at her instigation).** This, piled on top of other circumstances, left me paralysed with depression for several months; I’m very lucky I didn’t totally screw my chances of getting a degree. Of course being male, and young, and not really knowing what was happening, I never got medical help but just tried to struggle on.
Since then, although I have had bouts of more serious depression, above the background level, I am not conscious of any particular thing which has been a trigger. I’m lucky in that I have never been seriously suicidal or into self-harm; that’s something I’ve not had to cope with. Nor do I have bipolar disorder: I never have the highs.
But one general trigger does seem to be a high level of change and overload. Too much to do and/or too much change. This happened when I was at work; everything occasionally got on top of me and I had to take a duvet day. This did my career and reputation no favours, and I was well aware of it. This is also why I never pushed to get higher up the ladder than I did; I knew I didn’t want the aggravation that went with it, much as I would have liked the recognition. It is also why I ended up retiring early, because I could not have done another year of the “project from hell” I was working on.
And this overload/change effect still happens, because I still keep doing things. I cannot not be involved. If I didn’t get involved I fear I would quickly vegetate. As someone expressed it to me the other day: “if I sat at home all day I’d go senile”.
But sometimes everything gets too much. I try not to let it get in the way of things I have committed to do for other people – just as I tried to avoid it affecting my professional life. But that means all too often the fallout descends on my personal life. Hobbies get neglected; and far too often I end up ducking out of something we’ve booked to do. However much I need to find that space, I always feel bad about it because it always affects at least Noreen as well. I’ve got to the stage where the only real way to mitigate this is to book as little in advance as I can. And that in itself is demoralising and depressing.
I’m very lucky in that Noreen does her best to understand this and ride with it, even if she cannot really understand from the outside what the depression is actually like on the inside. Understandably she feels helpless to do anything to alleviate my suffering. I’m continually surprised, and hugely grateful, that Noreen is as understanding and patient as she is. She does a lot to help: doing bits and pieces for me; mopping up after me; quietly, behind the scenes, helping me achieve a lot of the things I get involved in. And she stops me getting involved in too much! I don’t think she realises just how much difference she makes and just how grateful I am. In this I am truly lucky; it is probably the one thing which really keeps me going.

On Depression — I

This is the first of a series of articles on depression — my depression. They are written from a very personal perspective; they are my views of how I see things working and what it feels like on the inside. Your views and experiences may be vastly different. My views and experiences are not necessarily backed by scientific evidence or current medical opinion. These articles are not medical advice or treatment pathways. If you think you have a problem then you should talk to your primary care physician.

My name is Keith. I have depression.
I have been in a serious bout of depression for most of the last 6 months — yes all summer and autumn — and I have no clue why.
I’ve decided to write a occasional things about depression; my depression. Just because.
Unless you are one of the half a handful of people closest to me you would probably not know I have depression, because most of the time when I’m out and about I can put on a mask to hide it and function more or less normally.
I want to get rid of the depression but I don’t have the first fucking clue how to.
No that isn’t an invitation to tell me how to do it – so please don’t! — because over the years I have tried almost everything and it hasn’t worked (as you’ll see by reading on).
I’ve been on antidepressants for many years; this time around I know it is well in excess of 12 years because I was on them when I changed doctors shortly after the millennium. I’ve been on the tablets for so many years I no longer have a clue whether they are doing any good, but currently it feels as if they’re useless.
Unfortunately the antidepressant I’m on is one of the worst for withdrawal symptoms when you try to get off them. I’ve had several attempts over the years but failed every time. After talking with my GP recently I’m currently having another attempt to switch to a different antidepressant. I’m hopeful this time I will succeed; but I’m fearful that I won’t.
What makes this worse is that I don’t really know why I have depression. I know that it is multifactorial and I know what some of those factors may be. For instance I know that I am worse during the winter and that I do technically have mild SAD (I was tested for that about 25 years ago). I know change and overload are also big factors. And there may be a genetic predisposition as my father and his father were also both depressives. Worrying about all the things I know I should do (exercise, lose weight, blah, blah, blah) makes the depression worse too. So it isn’t as if there is one cause which I can change to fix the problem. I wish there were.
Along with the depression, for me, go anxiety and panic attacks. Fortunately the panic attacks are now relatively rare; much rarer than they were back in the 1990s. But only because I have found strategies to avoid putting myself in the position where they are likely to happen; so I can to a large-ish extent control this.
For instance, I dislike the London Underground: the motion; the lack of fresh air; being packed in like sardines; the claustrophobia. So ask me to travel on a packed tube train and you’re asking me to have a panic attack. So I don’t travel on the underground if I can avoid it, although short distances and the over-ground parts are doable, sometimes. I feel similarly about buses, although there the problem is more to do with motion sickness — something I’ve always suffered from. Compensating for this gets expensive as it means using taxis. And luckily I am OK with normal trains; I’ve always loved proper trains.
Here’s a useful graphic which will tell you a lot more about depression. (Click the image for a larger, readable, version.)

Book Review: The Incredible Unlikeliness of Being

Alice Roberts
The Incredible Unlikeliness of Being: Evolution and the Making of Us
Heron Books, 2014
Alice Roberts is Professor of Public Engagement with Science at the University of Birmingham, and is perhaps the outstanding scientific polymath of our age: medic, anatomist, anthropologist, archaeologist, television science presenter and no mean artist. The Incredible Unlikeliness of Being is her latest book and sets out to unfold for us the amazing way in which we develop as an embryo and foetus and some of the ways in which we have probably evolved to this. And what an amazing voyage we are taken on!
I found the book immensely interesting and very readable. Roberts’ style is light, airy and chattily personal, while being scientifically accurate and informative — at times amusing and even ribald: how many authors could get away with a section entitled “Mind the Bollocks”? In fact I found the book so readable I had to ration myself to one or two chapters a night otherwise I would have devoured it in a single all night read.
We are taken on a journey from conception to birth with a look at how all the major systems of the body develop throughout pregnancy from the single egg and the successful sperm to the birth of a baby. Along the way Roberts describes the embryology, including insights from her own two pregnancies and the medical tests she has had done on her in the interests of science.
But more than this, she also discusses the archaeological evidence for how and why evolution has given us the kit of parts we have; how evolution got to produce them; and why they are different from other species. Right at the beginning of the book Roberts discusses the various theories of embryos and how babies are built from Aristotle to the present day. She is at pains to point out that each of these theories was consistent with the state of knowledge at the time so we shouldn’t scoff at them for being ignorant — one day our theories will be considered equally backward in the light of new knowledge.
Yes, I thoroughly enjoyed this book, but that doesn’t mean I don’t have reservations about it. It is a book for the scientifically (specifically, medically) literate layman. Roberts, rightly in my view, calls things by their correct scientific and medical names but I felt too often missed the opportunity to explain those names; what the part is or does. Of course the downside of providing more explanation is that it could disrupt the flow of the text (and make for a larger, more expensive book).
However I think there is a solution, at least in part, to this problem. The book is illustrated by Roberts’ own delightful line drawings — a very real demonstration of her skill as an anatomist! But there are for my money far too few illustrations. There were many occasions where I felt that a drawing (or other illustration) could have made the text much more powerful: especially in cases where the anatomy of different species, or at different stages of development, is being compared. Yes, some of those drawings are there, but for me too few. And drawings could have been used to explain some of the otherwise unexplained. In this respect I wanted more.
My other gripe is one which I all too frequently have to level at modern publishing (rather than authors): the poor quality of the paper used. Yes everyone wants to keep cost down and at £19.99 for almost 400 pages in hardback this is at the cheaper end of the spectrum. But oh that poor quality paper, which will not stand the test of time.
These are, however, relatively minor complaints about a book which I found informative, hugely interesting and immensely readable. I definitely came out somewhere different to where I went in!
So if you are interested in how babies grow in the womb, and how we got to be the shape we are, then I would thoroughly recommend this book.
It really is just so unlikely that we are all here, and as “normal” as we are!

Welsh Cannabis

Following on from the previous post about the liberalisation of prostitution, here’s another piece of unexpected sensible news.
The NHS in Wales will be the first in the UK to fund a cannabis-based medicine for people with multiple sclerosis. The drug in question is Sativex which has been on the market for some time.
Bravo for them as this is in line with current medical research, but directly contrary to the the recent draft NICE clinical guideline which rejected the drug for use on the NHS in Wales and England based, apparently, on a flawed assessment of its cost effectiveness.
You see, by chipping away, entrenched attitudes can be changed.

More links to items of interest which you may have missed. Quite a science based set this time, although again none of it too deep that non-scientists will get totally lost!
To start off this holiday season, what causes the scent of the sea? And no, it isn’t ozone as everyone believes!


Quickly followed by a quick look at the chemistry of insect repellents.
From insect pests to bacterial pests … A new study suggests that culling badgers is going to have next to no effect on bovine TB and the only way to constrain it is with mass culls of cattle. Sadly there’s probably zero chance the politicians will listen.
Following on from which George Monbiot is (quite rightly) scathing about the way the government is attempting to prevent the reintroduction of wildlife to the UK by using the Infrastructure Bill currently before parliament.
And here’s a piece on how we need to change the way we produce food if we are to be able to feed the ever increasing world population. Basically the whole global food narrative has to change because the current one, even with known tweaks, won’t work!
While we’re on food, here is a piece debunking ten common claims about genetically-modified crops. Yes, I understand the science, but I’m still not entirely comfortable with GMOs.
More food … This time it’s cheese, and a look at the work going on to understand the complex web of bacteria and fungi which turn milk into different types of cheese.
An important article looking at how we have to understand the statistical basis for evaluating actions (medical, social etc.). We have to measure their effectiveness against the background expected death rate (say), rather than against zero deaths.
[Trigger warning, especially for those who may have had miscarriages etc.]
Now let’s slide quietly into the medical arena with a look at the human placenta and the work that is going on to really understand it’s complexity and involvement in gestational and neonatal problems.
Here’s another important piece by the ever-excellent Prof Alice Roberts on how some hormonal contraceptives might be making PMS worse. And apparently this is something many women and lots of GPs do not understand well enough.
Here are twenty things you didn’t know about teeth.
And still on things medical, an interesting article by Carl Zimmer on the mysteries surrounding human blood groups and why we have them.
Now how’s this for a piece of lateral thinking? … A team of scientists are working on a system to use bubble wrap for conducting cheap blood and bacterial tests out in the field, away from the pathology lab, and where cost is a major issue.
The modern bathroom is a wasteful and unhealthy design. But it seems to stay that way because it is space efficient.
So at last we slide into psychology with an article on why the much hated Myers-Briggs test of personality types is totally meaningless.
I don’t pretend to understand Islam, so I found this infographic on the relationship between the various Islamic Sects very illuminating. Now will someone please do the same for Christianity and Buddhism.

And finally … A group of physicists and mathematicians are using mathematical tools to look at the complex social relations in the Icelandic Sagas (as well as other texts) and finding new things that literature specialists haven’t been able to unravel.
