Monthly Links for December

2 Comments

So here we are with the last round of Monthly Links for 2024, and were ending with a fairly bumper bundle …

Science, Technology, Natural World

dog-like ancestral mammal

Let’s start off with Quanta Magazine‘s reviews of science during the year. [All are LONG READS]
The Year in Physics
The Year in Biology
The Year in Maths
The Year in Computer Science
For some reason Quanta don’t cover chemistry or medicine.

There’s this idea in theoretical physics that we are living in a simulation, driven by some higher powers. And now there is a possible new law of physics which could support this.

The mathematics of random gatherings is a bit of a riddle.

Exponential growth can be somewhat counter intuitive.

Meanwhile scientists have tossed 350,757 coins to prove that they’re not 50/50 heads/tails and that a fair coin is probably impossible.

By most standards our modern atomic clocks are pretty accurate, but they’re about to be superseded by nuclear clocks which are orders of magnitude even more accurate.

Somewhat at the other extreme there’s an ancient piece of space hardware which is surprisingly still working well beyond it’s intended lifespan.

Talking of space hardware, there’s growing concern at the quantity of space junk left flying about up above, and how it could destroy all possibility of further space missions.

There are, as NASA have discovered, a whole host of so-called “dark comets” flying about above our heads.

Let’s come back to earth, or rather the sea … a strange, previously unknown, predatory crustacean has been found miles deep in an ocean trench off the west coat of South America.

Land predators aren’t going to be left out … the 280-million-year-old fossil of a dog-like predator which is likely one of our oldest mammal ancestors, has been found in Spain (above).

From dogs to cats … scientists have made a lot of progress unravelling the complex genetics of ginger cats.

Finally in this section, Independent SAGE, which was formed early in the pandemic to communicate good and transparent science, have been doing some navel-gazing to see what they could have done better. There are two summaries by Kit Yates of the published research paper: activities and organisation and lessons learnt.

Health, Medicine

Although it’s now a bit late for Christmas 2024, here are some generally applicable ways, from a GP, to avoid some common health hazards.

The science and medical community are getting worried about a possible pandemic of H5N1 bird flu. But how close are we really close to a pandemic?

Meanwhile Bob Hawkins is writing a series of four articles on how one models a pandemic in order to understand how various scenarios play out. Here’s part 1, part 2 and part 3.

Here’s a look at why it makes sense to vaccinate boys against HPV.

Poliovirus has been found in wastewater in Spain, Germany and Poland. How important is this?

One of our most common symbols of Christmas, mistletoe, provides a number of therapeutic agents.

The Vagus Nerve, our most complex nerve, is responsible for the messaging associated with many of our organs, but it’s role in mental health is also being unravelled. [££££] [LONG READ]

Sexuality

It seems that sexual identity is much more fluid than we previously thought.

Sex educators provide 16 ways to talk to your children about bodies, porn and consent.

Environment

So how much do we know about really old people, and how reliable is it? [LONG READ]

Sweden is almost a cashless society, and that’s not good for who are left out.

Art, Literature, Language, Music

As one had always suspected, “Word of the Year” is a marketing gimmick which tells us nothing about the actual state of the world.

Many authors place imaginary books within their own real books. Now there’s an exhibition in New York which brings some of these imaginary works of literature to life.

History, Archaeology, Anthropology

Let’s start off with a summary of ten fascinating archaeological discoveries of 2024. [LONG READ]

It seems highly likely that the first tools were made from plants, not rocks; but it is difficult to prove. [££££] [LONG READ]

A Bronze Age pit in Somerset has revealed evidence not just of mass murder, but also cannibalism.

Back around 4500 years ago, the area which is now Iran is known to have had a number of sophisticated board games including the Royal Game of Ur; and of course there are no manuals. Now two researchers have looked at another of these games, which has not just the board but also many of the pieces, and worked out a possible set of rules for the game. (If you really want brain-ache, follow the link to the preprint paper at the end of the linked article for a detailed explanation.)

In Norway, a number of Viking women’s graves have revealed jewellery, coins, and a ‘vulva stone’

An archaeological site in Kent is turning up lots of Anglo-Saxon finds, including a remarkably well preserved sixth-century sword.

Two articles on the plethora of archaeological finds from the reconstruction of Notre Dame. First from Science and second from Good News Network.

Unexpectedly, letters from Elizabeth I, Benjamin Franklin and Lord Byron are among a collection discovered in British stately home.

Around the globe there are around 8,500 shipwrecks from WWI and WWII, and many are now a ticking time-bomb of pollution, or worse.
Polluting shipwrecks are the ticking time-bomb at the bottom of our oceans.

Food, Drink

Now here’s a curiosity … Diamond Geezer has discovered that the British are drinking a lot less tea than 50 years ago, but coffee consumption is about the same.

cup of tea

Lifestyle, Personal Development, Beliefs

People have always needed to make sense of the world within their knowledge span, so they end up believing all sorts of things which later generations reveal to be rubbish.

Here are three articles from Corey S Powell in which he takes a cosmic look at thought …
Perspective from the stars
You Are a Ripple of Information
Your information bubble is your legacy

How Polynesian voyagers navigate Earth’s biggest ocean.

So just why don’t more women choose to propose to their male partners? Spoiler: patriarchy.

Once they reach 40 many women become invisible to men, and they won’t all accept it. [££££]

Scientists have found a surprisingly intact sabre-toothed tiger kitten frozen in Siberian ice, and it’s revealing unknown details about the species.

In 2023 researchers sent a dummy alien signal to Earth, without telling anyone, and it has now been decoded although not understood!

Jupiter is large enough to swallow at least 1000 Earths, and yet it has no surface.

NASA has a large number of satellites studying the sun, and they’re providing some surprising discoveries unrelated to the sun.

Look deeper and you find that comets have sinkholes, which generate jets of material.

In another piece of work from NASA, they’ve discovered two galaxies, looking like bloodshot eyes, which seem to be in the process of merging.

And finally in this section, astronomers have rediscovered a “dandelion-like” supernova first spotted in 12th-century China and Japan. [££££]

Health, Medicine

H5N1 bird flu has been detected in pigs, which is a big cause for concern as they are a well-known “mixing vessel”. And a teenager hospitalised in Canada has H5N1 with mutation(s) which may make it more transmissible between people.

It turns out that humans evolved to share beds, and not only with their romantic partner.

Synaesthesia is strange (especially for those of us who don’t have it) but ticker-tape synaesthesia, where real life comes with subtitles, is really bizarre.

Sexuality

Girls, is it that you just don’t like sex, or is it that you don’t like patriarchal sex? [LONG READ]

So how do you like your dirty talk during sex? [££££]

Is using lube really that much of a taboo for straight couples? Seems it is. [££££]

Environment

OK, so let’s change track …

Japan tiny forest

Apparently British cities are taking on the Japanese concept of “tiny forests“.

And in a similar vein, relatively small patches of wildflowers in cities are as good as natural meadows for insect biodiversity.

History, Archaeology, Anthropology

An amateur archaeologist has discovered another two stone circles on Dartmoor, and believes they add to the theory of a sacred arc of stone circles.

So who was Gunhild? And was she a victim of medieval ethnic cleansing?

On the other side of the world, a postgraduate student has serendipitously found a lost city in the Mexico jungle.

In Leicester they’ve found an 800-year-old burial pit containing 123 bodies, and it’s a complete mystery.

In order to make sense of the world as best they could medieval people had lots of supernatural beliefs: elves and fairies; abductions and the undead.

On which subject, here’s a look at some medieval animal ghost stories.

When you’re a peasant economy and don’t have the resources to feed lots of livestock through the winter, November becomes Blotmonath, the month of animal sacrifice and trying to store the meat.

The British Library currently has an exhibition Medieval Women: In Their Own Words. Here’s a review.

Food, Drink

Our drinking water contains many “forever chemicals”, but practically and personally what can we do to ameliorate this?

Wow! Ha ha!

So it’s that time of year, the season of Winter Vagina.

Monthly Links, October

So once more, somehow, another month passes and we come around again to this month’s selection of links to items you didn’t know you didn’t want to miss!

Science, Technology, Natural World

Starting here, it’s all downhill, because it seems that a lot of science is actually faked.

Fly brains may be tiny in size but they’re still stuffed with very complex inter-weavings of thousands of neurons, so it’s amazing that researchers have managed to map every neuron. Two reports, first from BBC, and second from Scientific American [££££].

At a different level, scientists have analysed ancient DNA to unravel how the endangered Iberian Lynx avoided extinction.

Some fish in the sea are so bizarre … here’s one that walks on six legs, and those legs can smell its prey in the sand. [££££]

Still at sea, but now above the water, research has found that the windless doldrums around the equator are caused in a completely different way than previously thought.

Staying with things geographical, apparently Mount Everest is still getting taller and not quite in the way we might expect.

It’s no great surprise that scientists have found that the asteroid which wiped out the dinosaurs was not a one-off.

And talking of meteorites, there was a mega meteorite about 3 billion years ago which was at least the size of Greater London which boiled the ocean and created a 500km wide crater.

NASA has shut down one of Voyager 2’s five remaining instruments to save power.

And finally in this section, did the early universe balloon in size with “cosmic inflation“, or is there a much simpler explanation?

Health, Medicine

This month’s medical matters are all to do with reproduction, in one way or another …

There are many genetic changes that link puberty to other aspects of physiology and affect its timing.

Prof. Christina Pagel highlights why we need to stop ignoring period pain and heavy bleeding!

Why is it that many doctors don’t believe women about the menopause? [££££]

At which point the Guardian asks if wearing a bra makes breasts more perky.

Let’s segue away from “women only” … in a move labelled “bonkers” by many, an NHS hospital in Norfolk has instructed staff that they must not describe babies as “born” male or female [££££]

And finally to the morgue where pathologists have found, during an autopsy, that the deceased 78-year-old man had not two, but three penises – and it is only the second ever such report and the first in an adult. Two reports, from Popular Science and Gizmodo. And the published academic papers make interesting reading!

Environment

In the hope of re-establishing colonies right across Britain, a number of pine martens have been released at a secret locations in Devon.

Social Sciences, Business, Law, Politics

It is being alleged that companies will no longer want to force people to change passwords every few weeks to counteract cyber attacks. I’ll believe it when it happens.

Art, Literature, Language, Music

An illustrator talks about how she went about a big commission.

Brits are forever complaining about the relentless invasion of English by Americanisms, but British English regularly invades the US.

History, Archaeology, Anthropology

What?! So little history this month?!

Archaeologists have found a very rare Bronze Age wooden spade in southern England.

Archaeologists have found another tiny house in Pompeii which is decorated with erotic frescoes.

Going Medieval finds that medieval people were just as much into side hustles as their modern counterparts.

Food, Drink

White mulled wine seems set to be a thing in UK this Christmas, with Marks & Spencer taking the lead.

Why did European cuisine become so bland? Apparently because snobbery decreed the removal of all the spices and contrasting flavours from the cuisine.

Is it possible to make a commercial, ethically responsible, and tasty fish finger?

Lifestyle, Personal Development, Beliefs

We should put down our mobile phones and get back into the habit of reading

So just why shouldn’t women propose marriage to men?

And last, but by no means least …

Monthly Links

Our packed monthly round-up of links to items you may have missed …

Science, Technology, Natural World

First up we have to highlight this years Ig Nobel prizes.

Palaeontologists have discovered several new species of extinct bone-crushing Tasmanian Tigers.

At the other end of the size scale, researchers looking in a Tibetan glacier have found over 1700 different frozen viruses.

Still with research reported in Popular Science magazine, the social white-browed sparrow weavers varying nest shapes demonstrate that birds have “culture”. Mind I thought we already knew that from the dialects of Meso-American parrots.

And while with “culture” apparently marmosets have individual “names” for each other.

Grief is well documented emotion in humans, and it seems some other species, but do cats grieve?

Scientists continue to unravel the meaning of our dreams.

So how do you know what that smell is? How does our sense of smell work? [LONG READ]

Leaving the animal world for the geological, in September 2023 something made Earth ring like a bell for nine days. [LONG READ]

Back in the early life of the solar system, it seems that Jupiter’s moon Ganymede was struck by an asteroid bigger than the one which wiped out the dinosaurs.

The asteroid Apophis is due to fly by very close to Earth in 2029, and now an astrophysicist is predicting a very slightly higher chance it may hit us.

Meanwhile, way out in the universe, researchers have discovered the largest jets ever from a black hole – and they make our galaxy look miniscule.

OB/GYN Dr Jen Gunter shares some takeaways from the recent (American) Menopause Society Meeting.

Our bodies are full of nerves, but the longest one orchestrates the connection between brain and body.

While on brains, within the billions of neurons they contain there are trillions of typos – some good, some bad. [LONG READ]

And still on brains, it’s being suggested that many older people don’t just maintain, but actually increase, their cognitive skills. [££££]

And finally with things mental, a Stanford-led research group has identified six different types of depression each of which is likely to respond differently to various treatments. [LONG READ]

Sexuality

Philip Curtis, the director of The Map House in London, talks about mapping Antarctica.

History, Archaeology, Anthropology

In Britain we are generally pretty ignorant about the way in which ancient India shaped science and mathematics.

Archaeologists in Spain have used DNA to uncover some of the secrets of a Christian cave-dwelling medieval community.

Meanwhile in Poland archaeologists have found the burial of two children suspected of being vampires.

Henry VIII did many notable things including accidentally changing the way we write history.

London

Our favourite London blogger, Diamond Geezer, visits Theobalds Grove (one stop outside Greater London). This is my home town; I was brought up just three minutes walk from this station! Needless to say it’s changed quite a bit since I last lived there in late 1970s.

I lived a couple of hundred yards down the road to the right of the church

Lifestyle, Personal Development, Beliefs

So just why do men bother with depilation?

Emma Beddington set out to see what it’s like to spend a day as a dog, and finds it impossible.

Once more unto our monthly links, brethren …

Science, Technology, Natural World

fish-like arthropod

The fossilised remains of a 500-million-year-old fish-like arthropod suggests it was among the first creatures with jaws. [££££]

There’s a living fish with a genome 30 times that of a human, and it’s just been sequenced.

Continuing with odd research findings, it seems that all modern birds share an iridescent ancestor.

And well what do you know? Apparently parrots have accents.

And now to tiny wings … scientists are doing all sorts of probes into honey and finding it can tell a huge story about the environment where it was created – it’s full of pollen, DNA, bacteria, and a lot of other junk. [££££]

Back to one of my favourite themes: wasps.
Each summer, wasps in the UK capture about 14 million kilogrammes of insects such as caterpillars and greenfly, making them important friends to gardeners.
First Prof. Seirian Sumner (aka. @waspprof) looks at why there are so few wasps around this year. (Spoiler: wet Spring.)
Secondly, yet another look at the importance of wasps as both predators and pollinators.

Tardigrades, those almost indestructible micro-creatures, that have been preserved in amber are revealing when they gained their indestructability. [££££]

Psychological research has a problem with reproducibility, and now there are indications that men may not be more attracted to scent of fertile women, after all.

Let’s explode another psychological stereotype … only children are no more self-centred, spoiled and lonely that those with siblings. [LONG READ] [££££]

As below, so above – maybe …

Astronomers have spotted a comet which is being kicked out of the solar system.

And NASA’s army of citizen scientists have spotted an object moving at an incredible 1 million miles per hour (that’s about 40 times round the Earth, an hour!).

Social Sciences, Business, Law, Politics

London blogger Diamond Geezer takes a look at why people are wrong.

Just a quick reminder that the original (ancient Greek) Olympic Games were entirely male and entirely nude.

Going Medieval takes a look at the medieval attitude to body count. [LONG READ]

Now much more up to date … Divers have discovered 100 bottles of champagne in a 19th-Century wreck in the Baltic.

Food, Drink

Last year’s Storm Ciarán’s ruined our tea. Here’s how.

A statistician looks at how to take the perfect penalty in football.

Scientists think they’ve discovered a cave on the moon, without being there.

So just how do astronomers work out the size of the solar system, again without going there?

And why do some planets have moons and others don’t?

And still in space, how often are we actually visited by asteroids?

Is it a fossil? Is it a meteorite? No it’s a meteor-wrong! [££££]

And finally for this section, we go from space to the ocean depths … Oceanographers think they’ve found an unexpected source of oxygen on the seafloor. [££££]

There are currently lots of sunspots and we’re nearing the solar cycle maximum … so the sun’s magnetic field is about to flip.

The search for a planet beyond Pluto has been going on since I was a kid, although astronomers can’t even agree Planet Nine exists, nor what they’re actually looking for.

Even so Planet Nine is amongst eight strange objects which could be hiding in the outer solar system – maybe.

Back down to Earth with a bump … Adam Kucharski asks “Can we predict who will win a football match?“.

Here’s a BBC News item about the beavers which have been reintroduced less than a mile from my house.

So it looks as if our invasive Asian Hornets have successfully overwintered here, although for some reason the government doesn’t see this as a huge problem!

…

How old is that termite mound? Researchers in South Africa have found 34,000-years-old termite mounds, beating the previously known oldest by 30,000 years!

Research is showing that our native wild orchids (not the tropical ones you buy in a supermarket) actually feed their seedlings through underground fungal connections. [££££]

Health, Medicine

How many of us are really aware that body organs aren’t always where they are supposed to be?

In addition you may have more body parts that you should have!

You should pay attention to your nipples – and this applies you you guys too, not just the gals – as they can tell you things about your health.

A chemist and an epidemiologist take a look at the whys and wherefores of sunscreen.

Apparently 80% of people with sleep apnoea are undiagnosed. Here’s what to look for.

Sexuality

How might one start a conversation about sex with a partner or teen?

A cancer diagnosis, or indeed any serious illness, can affect how we approach sex.

I’m used to seeing green parakeets in my west London garden – they’re noisy, they’re quarrelsome, but they’re colourful and often comic – so how did they actually get here from India?

In good news, it seems that the Iberian Lynx, one of the world’s rarest cats, is recovering from near extinction.

…

Social Sciences, Business, Law, Politics

Kit Yates lays out why it is important for democracy that we have a numerate society.

So what are the defining characteristics of a fascist? What should we look for?

History, Archaeology, Anthropology

First, Corey S Powell suggests that, like gravitational waves or ripples in a pond, we are just ripples of information in expanding outwards space-time. I see his point but I’m still trying to work out what it means.

And finally finally, a piece of science fiction suggesting that we could live forever if we merge biologically with the fungal network. [££££]

I suspect merging those two is going to be a bit like finding a unified theory of gravity and quantum mechanics.

Monthly Links

Behold, this month’s collection of links to items you may have missed. Let’s dive straight in as there’s quite a bit of science-y stuff this month.

Science, Technology, Natural World

Astronomers have been seeking the so-called Planet 9 for decades, but still can’t even agree that it is likely to exist.

Deep within Earth there are two giant mystery blobs. What do we know about them?

We all happily talk about the average this or the average that, but what do we mean by average, and why isn’t it always, well, average?

Now to the animal kingdom …

Many animals, including our pets, have a third eyelid, so why don’t we?

Try to get your head round this … Alan Turing’s pattern-generating mechanism for spots and stripes on animal coats; and how the mechanism is modified. [LONG READ]

Despite their size, gorillas have extremely small penises, and it turns out that the genetic mutations which cause this may also help human male fertility.

group of sperm whales

Scientists have been investigating the vocalisations of sperm whales for years, and some now think that they may be the elements of a language, with dialects.

A new to Britain exotic jumping spider has been found in Cornwall, and it isn’t the only one.

And on the subject of foreign arrivals, the Guardian has a sensible and thoughtful piece about the invasive Asian Yellow-Legged Hornet (Vespa velutina) which has invaded continental Europe and is trying to get a foothold in the UK. [LONG READ]
Here’s the BBC article which triggered my recent blog post on these hornets.
STOP PRESS: The Asian Yellow-Legged Hornet has now been discovered in a southern state of USA (Georgia to be precise)!

face of an Asian yellow-legged hornet

Still with wasps … It seems that many parasitic wasps have tamed viruses so they can use them to help subdue their prey. [LONG READ]

From hornets to their forest home … there’s a theory that trees are social and communicate with each other across the “wood wide web” of fungal filaments. But it is only a theory and some are arguing it is fantasy. [LONG READ]

Treat with extreme care … Bloodroot (Sanguinaria canadensis) is quite a pretty American Spring flower. But don’t go messing with it as the roots contain a blood red alkaloid, sanguinarine, which will shut down and kill any cells it comes in contact with, and more.

We all contain vestiges of our evolutionary past like goose bumps, extra nipples and the ability to waggle our ears. [££££]

Which brings us to several items about Neanderthals …
So what is the difference between Neanderthals and Homo sapiens? We interbred so there can’t be a lot, right?
There’s still debate about Neanderthals ability to talk.
Some aspects of our health seem to depend on DNA we inherited from Neanderthals.
And most weirdly, apparently the Neanderthal Y chromosome (which codes for male) has been lost, suggesting that human/Neanderthal hybrid males were infertile (in some form).

So is the menopause like puberty in reverse? Well, yes, and then again no. [LONG READ]

Most of us guzzle diet drinks and other low calorie goodies, but research is now indicating that the sweeteners are actually harmful to our gut and its microbes.

Archaeological research is now suggesting that (red) squirrels were instrumental is spreading leprosy and transmitting it to humans.

Egyptian Goddess Nut

One astrophysicist has been exploring the connection between the Milk Way and Nut, the ancient Egyptian Sky Goddess.

There’s a rare and very strange, apparently Roman, object (below) which was found at Norton Disney, Lincolnshire. The trouble is no-one knows what it is, or was used for, and there are a number of theories.

A 1,700-year-old Roman shipwreck found on the coast at Mallorca was loaded with fish sauce when it sank.

We know there was a thriving, early medieval Norse colony in Greenland, but why did it suddenly vanish in the 13th century?

So what was going on in London during the English Civil War (January 1642 to April 1646). [LONG READ]

London

Specifically now to modern London … London’s Royal Parks have their own plant nursery in the middle of Hyde Park, and IanVisits went to look.

Bhutan, the Dragon Kingdom, strictly limits visitors in order to protect its environment and heritage. But what is it like when you do go there?

Kate Lister asks how you know when you’re in love, and when you’re falling out of it. [££££]

A growing number of women are choosing to not have children. Here some tell what that’s like.

And finally on one of my hobbyhorses … the need to normalise and desexualise nudity if we are to achieve a well balanced society.

Monthly Self-Portrait, May

We’re staying with the medical for this month’s self-portrait. As long-time readers will know I have Obstructive Sleep Apnoea, which means I can stop breathing when asleep. To counteract this, I have a CPAP machine which pumps air into my airway overnight to keep the airways open. It isn’t invasive, just a nuisance, and it does cramp one’s style somewhat. As you’ll appreciate from the image, us users are sometimes colloquially termed “hoover heads”. This is my usual sleeping attire!

Monthly Links

Somehow we’ve almost got to the end of April, which means it’s time for our regular round up of links to items you may have missed. As well as the usual motley collection, we seem to have a lot of science-y stuff this month, so let’s get stuck in!

Science, Technology, Natural World

crab

It is interesting the way that Nature keeps evolving the same patterns independently. As an example, crabs have evolved five separate times.

Talking of the unexpected, researchers have used decades-old tins of salmon to track the health of the ocean’s fish stocks. [££££]

And on the subject of tracking … scientists in the UK have developed a trap which is an early warning system for Asian hornets.

And we keep the chain going … wasp researchers have agreed that the media is biased against wasps. Well who would have guessed!?

And now for something completely different … medical researchers continue to try to make sense of death and near death experiences. [LONG READ]

So why is it that some people always get lost, but others don’t? [LONG READ]

Researchers are using ancient records of previous total solar eclipses to help measure history.

I bet you didn’t know that billions of years ago the moon turned inside out, well sort-of. I certainly didn’t.

It’s well established that Stonehenge is aligned with the sun, but is it also aligned with the moon? Archaeologists and astronomers are about to use a rare lunar event to find out.

And still on space, NASA scientists have seemingly done the impossible and managed to bring the Voyager 1 probe back to its senses. Two, slightly different, looks in the Guardian and on Live Science.

Health, Medicine

An epidemiologist highlights that kids don’t need to get diseases to be healthy.

Here a medical health researcher looks at the UK’s failure in 2020 to “act fast and isolate” against Covid.

And staying on pandemics, the consensus amongst scientists is that the next pandemic will be caused by a flu virus.

Changing tack somewhat … a top OB/GYN looks at the basics of menstrual blood and explodes more than a few myths.

And another myth exploded … it seems that time-restricted eating is linked to a 91% (ie. almost double) higher risk of cardiovascular death.

Lastly in this section: you’ve heard of dyslexia, but do you know about dyscalculia? [££££]

Sexuality

The somewhat outspoken sex researcher, Dr Kate Lister, asserts that all straight men should try pegging once.

Meanwhile sex educator Dr Emily Nagoski talks to the BBC about sex and orgasm myths.

And coincidentally two women talk in the Guardian about their experiences of their unexpectedly open marriages. First Cassie Werber; and secondly New Yorker Molly Roden Winter. [BOTH ARE LONG READS]

IanVisits reckons that according to an inoperative law we have the date of Easter all wrong.

UK Supreme Court building

Politicians in the UK fulminate about foreign courts having sway over our law, when in fact there are more foreign courts on UK soil pontificating on affairs elsewhere in the world.

Now what have I been saying for years? … Using phonics to teach children to read doesn’t work.

Imaginary fashion art by Rose Wong

Here’s a blog post on the interesting work of New York artist Rose Wong.

Meanwhile Ian Dunt eulogises the word cunt.

Early medieval England saw a boom in the minting of silver coins, but until now no-one really knew why.

Mediaeval Mythbusting goes on the trail of the tales behind our more ancient pubs, including one of my favourites, The Mermaid in Rye. [LONG READ]

London

London once had dozens of iconic green huts which were cabman’s shelters. Now there are only 13 and the final one has just got heritage protection.

So here’s another look at the culture and usefulness of pubic hair.

And finally … Another of my favourite places in Dungeness, on which stands Prospect Cottage, the late Derek Jarman’s seaside home. It is sometimes open to the public, but the Guardian has some interior photographs.
