Your Monthly Links

So here’s our round-up of links to items which have caught our attention in the last month. There’s a lot in this month, so here goes …
Science & Medicine
Suspicious that expiry dates on products are a nonsense? Well that might be justified for some drugs.
The expected continual rise in life expectancy is slowing down. A leading medic suggests austerity is to blame.
It seems like what you always suspected may be true: a broken heart may damage your health.
We all know that cats purr. But do they purr only for our benefit?
An American veterinary service is working on making vet visits stress and fear free for nervous pets.
You thought plague was a thing of the past? Wrong. It is still alive and well in the American Southwest. Here’s the story of how one biologist tracks and identifies plague outbreaks before there’s harm to humans. [Long read]
Flying ants all seem to emerge on the same day. But do they?
Sexuality
Good news, lads! Science says you should masturbate 21 times a month – not that you needed an excuse! (Well actually they mean you should ejaculate that often; not necessarily the same thing.)
Environment
Jason Hickel in the Guardian posits that even if we all adhere to the Paris climate deal that isn’t going to be enough to save us – our future depends on de-growth
There’s a plan to reintroduce Eurasian lynx to the Kielder Forest.
Art & Literature
Worried about your books? Why not protect your library the medieval way with horrifying book curses?
History, Archaeology & Anthropology
Archaeologists are suggesting that a find of buried tools and pigments means humans reached Australia 65,000 years ago – that’s 18,000 years earlier than previously thought.
Yes, we knew the Romans had concrete. And now we know why it was so good that it still stands today when our modern concrete decays.
Infertility isn’t just a modern phenomenon. The mediaevals recognised it and realised that it could be the man at fault rather then the women – not really surprising as many in medieval times believed the embryo originated solely from the man. Oh and in true medieval style they concocted some horrid cures.


The Russian Hermitage Museum employs 74 cats just to keep its basements mice-free.
London
IanVisits investigates a south London experiment in tube tunnelling.
Lifestyle & Personal Development
What brings you happiness? Money? Stuff? Time? Surprisingly research is suggesting that you can gain the most happiness from freeing up time, even if that is paying someone to do things for you so you have the time to devote elsewhere.
So how often should you wash your bed sheets? A microbiologist looks at the problem.
On a similar note, here are a few suggestions for getting rid of pests and bugs the Buddhist way. While I can see some of this would work, a lot does seem rather unlikely.
To me this seems like a non-question: should teachers be allowed to have tattoos? Well why shouldn’t they; isn’t it all part of the life we’re supposedly educating our kids to navigate?
From which it is but a short step to asking whether witches are the ultimate feminists.
Shock, Horror, Humour
Two amusements to conclude this month …
An American researcher has used a neural network to generate a whole host of quaint, and sometimes rude, British place names.
And finally this summer’s latest fashion trend: Glitter Boobs …

Book Review: The Sex Myth

Brooke Magnanti
The Sex Myth: Why Everything We’re Told is Wrong
Weidenfeld & Nicolson; 2012
If, like me, you’re always doubtful of what “they” are telling us about sex (well actually about anything) then this book is an eye-opener. And who better to open our eyes than Brooke Magnanti, for if anyone knows then she should:

Brooke Magnanti studied Genetic Epidemiology and gained her PhD at the Department of Forensic Pathology, University of Sheffield. Her professional interests include population-based research, standards of evidence, and human biology and anthropology. In 2009 it was revealed that she is an ex-call girl and author of the bestselling Belle de Jour series of memoirs, which were adapted into the TV series, Secret Diary of a Call Girl.

She is also a novelist, blogger and activist who, in 2016, was called to give evidence about sex work conditions in the UK to the Home Affairs Committee investigating prostitution laws in Britain.
In describing the content I can’t do a lot better than the book’s cover blurb:

Is there any truth to the epidemic of sex addiction? Are our children really getting sexualised younger? Are men the only ones who like porn? Brooke Magnanti looks at all these questions and more – and proves that perhaps we’ve all been taking the answers for granted.
Brooke Magnanti is no stranger to controversy. As Belle de Jour she enthralled and outraged the nation … Now her real identity is out in the open, Brooke’s background as a scientist and a researcher comes to bear in this fascinating investigation into the truth behind the headlines, scandals and moral outrage that fill the media (and our minds) when it comes to sex.
… Brooke strips away the hype and looks at the science behind sex and the panic behind public policy. Unlike so many media column inches, Brooke uses verifiable academic research. This is fact, not fiction; science not supposition.

Don’t let the “science” label put you off. Yes, Brooke references all her sources but her style is light and eminently readable. She combines her skills in statistics, epidemiology and research with her experiences as a call-girl to blow the lid off what the Agenda Setters and politicians are telling us, thus exposing all the myths surrounding sex in society.
Brooke follows what the Agenda Setters and Evangelisers are saying and traces back where they get (or more usually fabricate) their data – and then by reference to peer-reviewed research shows where and how it is false. From sex addiction, through trafficking for sex, to the decriminalisation of prostitution, myths are well and truly busted.
If I had to find criticisms of the book they would be four, albeit relatively small: (1) It’s a shame the book is now 5 years old; it would be good to have an update. (2) Personally I would have liked more diagrammatic explanations of the data presented. (3) In each chapter a summary of the evidence, and how it is built into the arguments, would have helped my understanding of the (often necessarily) convoluted and detailed analysis. And (4) like so many books these days it could well be reduced in size by better design and typography and not printed on such cheap paper.
But that aside, the book is highly illuminating and well worth reading.
Overall Rating: ★★★★☆

The Conceptual Penis

Anyone who needs cheering up on a Sunday afternoon, could do worse than read Jerry Coyne’s blog post A new academic hoax: a bogus paper on “the conceptual penis” gets published in a “high quality peer-reviewed” social science journal – and the papers to which it refers.
If you don’t understand a word of it, that’s fine, because the paper being described, The conceptual penis as a social construct in Cogent Social Sciences, is a total and elaborate hoax which even the authors admit they don’t understand! Just as a small example:

Nowhere are the consequences of hypermasculine machismo braggadocio isomorphic identification with the conceptual penis more problematic than concerning the issue of climate change. Climate change is driven by nothing more than it is by certain damaging themes in hypermasculinity that can be best understood via the dominant rapacious approach to climate ecology identifiable with the conceptual penis.

The paper was designed to expose the trendy opaque nonsense of much of the social sciences. And it succeeded as it was published in a peer-reviewed journal.
The paper’s text sort of makes superficial sense – and I could see it becoming a radical feminist meme – but it is actually complete bollox. Enjoy it!

Radiation

There was a useful, if short, review by David Ropeik of Harvard in Aeon a couple of weeks ago under the title “Fear of radiation is more dangerous than radiation itself“.
This is something which has been said for a long time, but it is useful to have the threads pulled together in a referenced article.
As usual I’ll give your the tl;dr version.

The fear of ionising (nuclear) radiation is deeply ingrained in the public psyche … we simply assume that any exposure to ionising radiation is dangerous. The dose doesn’t matter. The nature of the radioactive material doesn’t matter. The route of exposure – dermal, inhalation, ingestion – doesn’t matter. Radiation = Danger = Fear. Period.
The truth, however, is that the health risk posed by ionising radiation is nowhere near as great as commonly assumed. Instead, our excessive fear of radiation … does more harm to public health than ionising radiation itself. And we know all this from some of the most frightening events in modern world history: the atomic bombings of Japan, and the nuclear accidents at Chernobyl and Fukushima.
Much of what we understand about the actual biological danger of ionising radiation is based on the joint Japan-US research programme called the Life Span Study … of survivors of Hiroshima and Nagasaki [see also here]… Within 10 kilometres of the explosions, there were 86,600 survivors … and they have been followed and compared with 20,000 non-exposed Japanese. Only 563 of these atomic-bomb survivors have died prematurely of cancer caused by radiation, an increased mortality of less than 1 per cent.


Based on these findings … the lifetime cancer death toll from the Chernobyl nuclear accident might be as high as 4,000, two-thirds of 1 per cent of the 600,000 Chernobyl victims … For Fukushima, which released much less radioactive material … UNSCEAR predicts that ‘No discernible increased incidence of radiation-related health effects are expected among exposed members of the public or their descendants.’
Both nuclear accidents have demonstrated that fear of radiation causes more harm to health than radiation itself … 154,000 people in the area around the Fukushima Daiichi … were hastily evacuated. The Japan Times reported that the evacuation was so rushed that it killed 1,656 people … The earthquake and tsunami killed only 1,607 in that area.
… … …
In 2006, UNSCEAR reported: ‘The mental health impact of Chernobyl is the largest public health problem caused by the accident to date’.
… … …
Fear of radiation led Japan and Germany to close their nuclear power plants. In both nations, the use of natural gas and coal increased, raising levels of particulate pollution and greenhouse gas emissions. Neither country will meet its 2020 greenhouse gas emissions-reduction targets.
… … …
Fear of radiation has deep roots. It goes back to the use of atomic weapons, and our Cold War worry that they might be used again … Psychologically, research has found that we worry excessively about risks that we can’t detect with our own senses, risks associated with catastrophic harm or cancer, risks that are human-made rather than natural … Our fear of radiation is deep, but we should really be afraid of fear instead.

Or in the immortal words of Rear-Admiral Sir Morgan Morgan-Giles: Pro bono publico, nil bloody panico.

Is the “Dildo of Damocles” daunting? What does/will happen when sex toys connect to the internet?
Environment
It is estimated that the Fukushima accident gave everyone on the planet radiation exposure equivalent to a single X-ray – although unsurprisingly those in Fukushima received rather more it was unlikely to be more than two year’s worth of background radiation, so tiny in the overall scheme of things.
Hedges are as important for the environment as trees, at least in cities.
In another non-obvious finding, research is showing that beaver dams keep streams cool.
History, Archaeology & Anthropology

Five Questions, Series 9 #4

With question four we’re getting near the end of this series of Five Questions.

★★★★☆

Question 4: How many even prime numbers are there?
I’m not sure if this is a trick question, mathematically, or not.
First let’s be clear what a prime number actually is. It is a integer number which is divisible only by itself and 1. All even numbers (2, 4, 6, …) are divisible by 2. So 2 itself, is therefore the only even numbered prime number. And given that the technical definition of a prime number is that it has to be greater than 1, the answer is that there is just the one even prime. And there is no trick. (See Wikipedia for a fuller description.)
But why might this have been a trick question? Well I thought it might be a trick, because I did wonder about 0. Is 0 odd or even? Well actually it doesn’t matter because dividing 0 by anything you get 0, not 1, which seems to negate the question, regardless of the technical definition of a prime number.
