Here’s our monthly round-up of items you may have missed previously. Slightly late again — apologies! There’s a lot here, this month too!
Science & Medicine
Research is showing that magpies possess self-awareness to rival that of primates, dolphins and elephants.

Humans are practically bald and are one of the very few (almost) hairless mammals which may be why we thrived as a species.
Now here is something which looks odd … it seems that women who have had their appendix removed are more fertile. Ditto for tonsillectomy.
So, the age old question … do women’s periods really synchronise when they live together? Spoiler: no.
A pain in the guts? Research is suggesting that the range and quantity of microbes in our guts may have a powerful effect on conditions like depression, MS and obesity.
However eating yoghurt is not enough to keep those gut living microbes in balance. [Long read]
Just like I’ve always known, travel sickness is a glitch between the brain, the ear, the eye and the stomach.
Now here’s one for the lads out there … just how big is a fart? Answer: somewhere between a bottle of nail polish and a can of drink. Maggie Koerth-Baker has the low down.
Your dentist knows — but likely won’t admit — what you have suspected: flossing is a waste of time.
IFLscience looks at the theories as to why time seems to pass more quickly as we get older.
Sexuality
The French (only the French?) have created a 3D model of the clitoris as an aid to their schoolchildren’s sex education.
Environment
So what is it really like to drive a Eurostar train? Andrew English in the Daily Telegraph finds it’s more complex than one might imagine.
Social Sciences & Business
So here’s something else we’ve always known: people who don’t have children benefit our environment more than any campaign. And that should be valued.
Noreen and I have done jury service three times between us. What are your chances of being called more than once.
Here’s our favourite zen master, Brad Warner, on whether “White Buddhism” is cultural appropriation.
History
There is something special on the Parisian road outside La Santé prison … the city’s last vespasienne urinal (below).

When the US Army took control of Japan after WWII they confiscated thousands of secret Japanese military maps, covering much of Asia, shipped them back to the US and dispersed them to libraries across the country for safekeeping. Now they are being brought back together and their historical interest realised.
London
In this new section, we look at items about my home city.
Once upon a time there was a plan to build a ginormous “Pyramid of Death” in London. Luckily it never happened.
Time Out looks at the complete history of Paddington Station.
Meanwhile Londonist takes a look at the history of floods on the Underground.
In another item from IanVisits he looks at the old North London Line which ran from Broad Street to Richmond, and is now part of the Overground.
It always surprises me what people can find by way of historic artefacts washed up on the Thames foreshore.
Londonist (again) looks at the top 10 of London’s “spy sites”.
And finally for London, here are nine places that apparently Londoners never go.
Shock, Horror, Humour
The Atlantic brings us the unbelievable, mysterious and Byzantine story of Jesus’s wife. [Very long read]
I often think that academics and medics, more than most of us, get up to some exceedingly strange things. One Dr Bruce Ragsdale has developed a taxonomy of the Occlupanida — this little plastic clips that are used to close plastic bread wrappers etc. Very odd.

And finally, thanks to the Guardian, Yes Minister explains everything about Brexit.
Phew! More next month …
