The morass of lies
It will come as no shock to regular readers of Skeptophilia that I really hate it when people make shit up and then misrepresent it as the truth.
Now making shit up, by itself, is just fine. I'm a fiction writer, so making shit up is kind of my main gig. It's when people then try to pass it off as fact that we start having problems. The problem is, sometimes the false information sounds either plausible, or cool, or interesting -- it often has a "wow!" factor -- enough that it then gets spread around via social media, which is one of the most efficient conduits for nonsense ever invented.
Here are three examples of this phenomenon that I saw just within the past twenty-four hours.
The first is about a Miocene-age mammal called Orthrus tartaros, "a distant relative of modern weasels," that was a scary hypercarnivore. Here's an artist's conception of what Orthrus tartaros looked like:
The second one cautioned the tender-hearted amongst us against catching spiders and putting them outdoors. "Spiders in your house," the post said, "are adapted to living indoors. 95% of the spiders captured and released outside die within 24 hours. Just let them live inside -- most of them are completely harmless."
While I agree completely that spiders have gotten an undeserved bad rap, and the vast majority of them are harmless (and in fact, beneficial, considering the number of flies and mosquitoes they eat), the rest of this is flat wrong. Given that here in the United States, conventional houses have only become common in the past two hundred years or so, how did the ancestors of today's North American spiders manage before that, if they were so utterly dependent on living indoors? And second, how did anyone figure out that "95% of the spiders captured and released died within 24 hours?" Did they fit them with little radio tracking tags, or something? This claim fails the plausibility test on several levels -- so while the central message of "learn to coexist with our fellow creatures" is well meant, it'd be nice to see it couched in facts rather than made-up nonsense.
The last one is just flat-out weird. I'd seen it before, but it's popping up again, probably because here in the Northern Hemisphere, it's vegetable-garden-harvest time:
What puzzles me about all this is why anyone would make this kind of stuff up in the first place. Why would you spend your time crafting social media posts that are certifiable nonsense, especially when the natural world is full of information that's even more cool and weird and mind-blowing, and is actually real? Once such a post is launched, I get why people pass it along; posts like this have that "One True Fact That Will Surprise You!" veneer, and the desire to share such stuff comes from a good place -- hoping that our friends will learn something cool.
But why would you create a lie and present it as a fact? That, I don't get.
Now, don't get me wrong; there's no major harm done to the world by people making a mistake and believing in the sexuality of peppers, doomed house spiders, and a Miocene hypercarnivorous weasel. But it still bothers me, because passing this nonsense along establishes a habit of credulity. "I saw it on the internet" is the modern-day equivalent of "my uncle's best friend's sister-in-law's cousin swears this is true." And once you've gotten lazy about checking to see if what you post about trivia is true and accurate, it's a scarily small step to uncritically accepting and reposting falsehoods about much, much more important matters.
Especially given that there are a couple of media corporations I could name that survive by exploiting that exact tendency.
So I'll exhort you to check your sources. Yes, on everything. If you can't verify something, don't repost it. To swipe a line from Smokey Bear, You Too Can Prevent Fake News. All it takes is a little due diligence -- and a determination not to make the current morass of online lies any worse than it already is.

Nerds FTW
I'd sort of accepted this without question, despite being one myself and at the same time happily married to a wonderful woman. The reason I didn't question it is that said wonderful woman pretty much had to tackle me to get me to realize she was, in fact, interested in me. You'd think, being bisexual, I'd have had twice the opportunities for romance, but the truth is I'm so completely oblivious that I wouldn't know it if someone of either gender was flirting with me unless they were holding up a sign saying "HEY. STUPID. I AM CURRENTLY FLIRTING WITH YOU." And possibly not even then.
Good thing for me, because not only am I a science nerd and a science fiction nerd, I write science fiction. Which has to rank me even higher on the romantically-challenged scale.
Or so I thought, till I read a study by Stephanie C. Stern, Brianne Robbins, Jessica E. Black, and, Jennifer L. Barnes that appeared in the journal Psychology of Aesthetics, Creativity, and the Arts, entitled, "What You Read and What You Believe: Genre Exposure and Beliefs About Relationships." And therein we find a surprising result.
Exactly the opposite is true. We sci-fi/fantasy nerds make better lovers.
Who knew? Not me, for sure, because I still think I'm clueless, frankly. But here's what the authors have to say:
Research has shown that exposure to specific fiction genres is associated with theory of mind and attitudes toward gender roles and sexual behavior; however, relatively little research has investigated the relationship between exposure to written fiction and beliefs about relationships, a variable known to relate to relationship quality in the real world. Here, participants were asked to complete both the Genre Familiarity Test, an author recognition test that assesses prior exposure to seven different written fiction genres, and the Relationship Belief Inventory, a measure that assesses the degree to which participants hold five unrealistic and destructive beliefs about the way that romantic relationships should work. After controlling for personality, gender, age, and exposure to other genres, three genres were found to be significantly correlated with different relationship beliefs. Individuals who scored higher on exposure to classics were less likely to believe that disagreement is destructive. Science fiction/fantasy readers were also less likely to support the belief that disagreement is destructive, as well as the belief that partners cannot change, the belief that sexes are different, and the belief that mindreading is expected in relationships. In contrast, prior exposure to the romance genre was positively correlated with the belief that the sexes are different, but not with any other subscale of the Relationships Belief Inventory.Get that? Of the genres tested, the sci-fi/fantasy readers score the best on metrics that predict good relationship quality. So yeah: go nerds.
As Tom Jacobs wrote about the research in The Pacific Standard, "[T]he cliché of fans of these genres being lonely geeks is clearly mistaken. No doubt they have difficulties with relationships like everyone else. But it apparently helps to have J.R.R. Tolkien or George R.R. Martin as your unofficial couples counselor."
Tolkien? Okay. Aragorn and Arwen, Galadriel and Celeborn, Eowyn and Faramir, even Sam Gamgee and Rose Cotton -- all romances to warm the heart. But George R. R. Freakin' Martin? Not so sure if I want the guy who crafted Joffrey Baratheon's family tree to give me advice about who to hook up with.
One other thing I've always wondered, though, is how book covers affect our expectations. I mean, look at your typical romance, which shows a gorgeous woman wearing a dress that looks like it's being held up by a combination of prayers and Superglue, being seduced by a gorgeous shirtless guy with a smoldering expression who exudes so much testosterone that small children go through puberty just by walking past him. Now, I don't know about you, but no one I know actually looks like that. I mean, I think the people I know are nice enough looking, but Sir Dirk Thrustington and Lady Viola de Cleevauge we're not.
Of course, high fantasy isn't much better. There, the hero always has abs you could crack a walnut against, and is raising the Magic Sword of Wizardry aloft with arms that give you the impression he works out by bench pressing Volkswagens. The female protagonists usually are equally well-endowed, sometimes hiding the fact that they have bodily proportions that are anatomically impossible by being portrayed with pointed ears and slanted eyes, informing us that they're actually Elves, so all bets are off, extreme-sexiness-wise.
So even if we sci-fi nerds have a better grasp on reality as it pertains to relationships in general, you have to wonder how it affects our bodily images. Like we need more to feel bad about in that regard. Between Victoria's Secret and Abercrombie & Fitch, it's a wonder that any of us, male or female, are willing to go to the mall without wearing a burqa.
But anyhow, that's the latest from the world of psychology. Me, I find it fairly encouraging that the scientifically-minded are successful at romance. It means we have a higher likelihood of procreating, and heaven knows we need more smart people in the world these days. It's also nice to see a stereotype shattered. After all, as Oliver Wendell Holmes said, "No generalization is worth a damn. Including this one."

Life during chaos
If there's one place and historical period I could choose to know more about, it would be England during, and immediately following, the withdrawal of the Romans in the fifth century C. E.
For one thing, this would settle once and for all the question of whether King Arthur was a real historical personage, a completely fabricated legend, or somewhere in that gray area in between. Whoever (or whatever) he was, I doubt our picture of him was anywhere near accurate:
In any case, besides finding out more about the King of the Britons, I'd love to have more knowledge about what exactly was going on back then. There are very few written records from Britain following the withdrawal of Roman troops from the northern and western parts of the island by the (usurping) Emperor Magnus Maximus in 383. Things stabilized a little after Magnus was deposed and executed in 387, but Roman rule in the west was definitely crumbling. The final blow came in 410 when Roman settlers in what is now southern England -- many of whom had been born there -- pleaded for help from Rome against the "barbarian" Celts, who were not above taking advantage of the instability, and Emperor Honorius basically told them to bugger off and take care of their own problems because he had more pressing concerns, the biggest being that Rome had just been sacked by a shitload of Visigoths.
This meant that running England fell to whoever could manage to keep their head on their shoulders long enough to do so. In some places, these were the Romano-British magistrates who chose not to decamp when the powers-that-be back on the Italian peninsula left them to their own devices; in other places, Celtic or Pictish warlords. This period saw the beginning of the Saxon invasions from what is now Denmark and northern Germany, something that would historically and linguistically change the entire face of the country.
But the fact remains that we don't know much for certain. The earliest record we have of the era was written at least a century after the events it chronicles -- Gildas's De Excidio et Conquestu Britanniae (On the Ruin and Conquest of Britain) -- but it contains as much hagiography and finger-wagging about pagan sinfulness as it does history. (For what it's worth, Gildas doesn't even mention King Arthur; the first time the Once and Future King appears in a written record is Nennius's Historia Brittonum, from around 900. If Arthur was real, this omission seems a little curious, to say the least.)
In any case, between the withdrawal of the Romans in 410 and the unification of England under King Æthelstan of Wessex in 927, we don't have a lot of reliable sources to go on. To be fair to the English, they had other fish to fry during those intervening centuries, what with the horrific Plague of Justinian ripping its way through Europe in the middle of the sixth century, repeated invasions by the Angles and Saxons, and then the depredations of the Vikings, starting with their destruction of the "Holy Island" of Lindisfarne in 793. Virtually the only people who could read and write back then were monks and clerics, and you have to figure that what they'd have been writing while they were being hacked to bits would have been gruesome reading anyhow. (Possibly, "Here may be found the last words of Joseph of Arimathea. He who is valiant and pure of spirit may find the Holy Grail in the Castle of Aaarrrrggh.")
The topic comes up because a new study out of the University of Cambridge that found something surprising -- at least in one region, the economy didn't tank completely when the Romans jumped ship. Pollution by heavy metals, as nasty as it can be, is a decent proxy record for the robustness of trade and industry; when things are really bad, chances are you're not going to be doing much smelting of silver, iron, and lead. The team, led by archaeologist Martin Millett, found that in sediment cores from the River Ure in Yorkshire, the levels of metal contamination stayed fairly constant throughout the period. This is evidence that the Roman settlement at Aldborough -- the Roman Isurium Brigantum -- continued to be a trading hub despite the chaos.
This, of course, doesn't tell you what was happening in other parts of the island. It could be that Aldborough just happened to hang on longer, for reasons we'll probably never know. Eventually, the plague and the repeated invasions caught up with them, too, and in the seventh and eighth centuries, there wasn't that much happening, at least not smelting-wise. The "Dark Ages" in England are "dark" not because they were necessarily any more barbaric than any other period, but because we know so little about them -- and this gives us at least a small piece of information about one town's fate after the fall of the Roman Empire.
I'm always attracted to a mystery, and there's something compelling about this period. Undoubtedly why there have been so many works of fiction that are set in pre-Norman England. It's nice to have one more bit of the puzzle, even if neither the worlds of Sexy King Arthur nor Silly King Arthur are likely to come anywhere near the reality of what life was like back then.

Looking for a signature
- ATP as an energy driver
- some form of sugar-fueled cellular respiration to produce that ATP
- phospholipid bilayers as cell membranes, and (for eukaryotes) for the internal membranes that compartmentalize the cell
- proteins to facilitate structure, movement, and catalysis (the latter are called enzymes)
- nucleic acids such as DNA and RNA for information storage and retrieval
- lipids for long-term energy storage

Flash in the pan
"There are more things in Heaven and Earth, Horatio, than are dreamt of in your philosophy."
So wrote William Shakespeare in Hamlet, and if anything, it's a significant understatement. If Shakespeare were writing today, considering recent discoveries in science, he might phrase it as, "Horatio, you seriously have no idea how weird it is out there. I mean, literally," which gains in accuracy but does lose something in poetic diction.
To take just one example, consider the paper that appeared in Astrophysical Journal Letters this week, about a gamma ray burst that was discovered by the amusingly-named Very Large Telescope (they're currently building a bigger one down in Chile which will be called, I shit you not, the Extremely Large Telescope). Gamma ray bursts are already pretty astonishing; NASA describes them as "second only to the Big Bang as the most energetic and luminous phenomena known." There are several possible causes of these enormous releases of high-frequency electromagnetic radiation -- supernovae, the catastrophic merger of neutron stars, and flares from magnetars amongst them. (You would not want to be looking down the gun barrel of one of these when it went off. There is some suspicion that the Late Ordovician Mass Extinction -- one of the "Big Five" mass extinctions, and second only to the Permian-Triassic "Great Dying" event in terms of magnitude -- was caused by a nearby gamma ray burst.)
Most of these events are one-offs, and considering the energy they involve (most of them release more energy in a few seconds than the Sun will in its entire lifetime) you can understand why. After one flare-up of that size, it's unsurprising that it wouldn't do it again any time soon. So the astrophysicists were puzzled when they found a gamma-ray burster (GRB 250702B) that seems to recur -- it produced a sequence of five flares, and did that entire sequence three times. Weirdest still, each time, the interval between the second and third flare in the sequence was an integer multiple of the interval between the first two!
What in the hell could cause that?
The gamma-ray burst seems to be extragalactic -- to be coming from a source outside the Milky Way. The source is near a known galaxy, but whether the burst is coming from within the galaxy, or simply from a source that happens to be lined up with it, hasn't been determined yet. The galaxy is one of the thousands that have been located by the Hubble and James Webb Space Telescopes but have yet to be studied; they don't even know what its red shift is (which would tell you how far away it is). But because the red shift of gamma ray bursts is impossible to determine -- to calculate red shift, you need identifiable spectral lines, and those don't occur in something as massive and chaotic as a burst -- this still wouldn't tell you whether the source was actually inside the galaxy or not.
In fact, there's more that's unknown than known about this phenomena. The periodicity led the researchers to suggest one possibility, that it was some unfortunate massive star in an elliptical orbit around a massive black hole, and having pieces torn off it every time it gets to perihelion. Another possibility is an "atypical stellar core collapse," which is astrophysics-speak for "a collapsing star where we really have no idea why it's acting like it does." A third is that the detected periodicity is an artifact caused by "dust echoes" -- reflection of the original gamma-ray burst from concentric shells of dust surrounding the remains of an exploded star. The final possibility -- at least of the ones the authors came up with -- is that it's an example of gravitational lensing, where light emitted by a star (or other astronomical object) travels close to a black hole, the curved space around the black hole causes the light beam to split along more than one path, and different parts of it arrive at different times.
The upshot is that we simply don't know what's going on here. The authors write:
We have... new, multiwavelength observations of a superlative series of associated GRB triggers, GRB 250702B. Our observations reveal a rapidly fading, multiwavelength counterpart likely to be embedded in a galaxy with a complex and asymmetric morphology. We... conclude that GRB 250702B is an extragalactic event. The relatively bright and extended host suggest the redshift is moderate (z < 1).
GRB 250702B is observationally unprecedented in its timescale, morphology, and the onset of X-ray photons prior to the initial GRB trigger. In addition, we find a striking, near-integer time step between the GRB outbursts, suggesting (although not proving) possible periodicity in the events.
All of this is absolutely fascinating to the astronomers, because it opens up the perennial question of "Is this a phenomenon we've already seen and know how to explain, or is it actually new physics?" At present, there's no way to answer this with any certainty. All that's known is something really weird is going on out there, and we're going to have to do a lot more observation before we'll be able to figure out what the explanation is.
So like I said, Shakespeare was spot-on. And the more we look out into the skies, the more we find that is Not Dreamt Of In Our Philosophy. Only now we have astrophysicists working on actually explaining these phenomena -- so perhaps this very peculiar flash-in-the-pan won't remain a mystery forever.

The phantoms of Jedburgh Abbey
Even so -- and despite the Scottish Reformation pretty well doing away with all the Catholic monasteries in Scotland -- part of the building was still used as the parish kirk. Finally, in 1871, it was deemed unsafe, and a new church was built; the remains of the abbey became a historical landmark, where it attracts tourists lo unto this very day.
It also is the home of a particularly terrifying pair of specters -- which, if you believe the ghost hunters, still sometimes can be seen stalking around the abbey grounds.
King Alexander III of Scotland (1249-1286), whose great-great grandfather David I founded Jedburgh Abbey, had a terrible time of it even judging by medieval Scottish standards, where life was (in Thomas Hobbes's immortal words) "solitary, nasty, poor, brutish, and short." He became king at age seven -- never a good way to start -- and his first years were dominated by a fight for power between two factions both determined to gain control over the young monarch. He married Margaret Plantagenet, daughter of King Henry III of England, but this only served to give Henry incentive to demand fealty from Alexander, entangling Scotland in another of the long conflicts it had with its neighbor to the south.
Along the way, Alexander had what would turn out to be his only real victory; in 1263 the Scots defeated the invading force of King Haakon IV of Norway at the Battle of Largs, and in the treaty that ended the conflict, Scotland gained ownership of the Hebrides and the Isle of Man.
But after that, things started to fall apart. Alexander's wife Margaret died in 1275, and all three of his children by her had followed their mother into the grave by 1284. As was typical of the time, Alexander started casting around for a second wife. His only heir was his grandchild, the daughter of his deceased eldest child Margaret who had married King Eric II of Norway, grandson of the defeated Haakon IV -- but the girl (also named Margaret) was an infant... and still lived in Norway.
Here's where it takes an even darker turn. Alexander fell for a woman named Yolande de Dreux, the daughter of a French nobleman. Yolande reciprocated his attention, but there was a snag -- she was already betrothed, to a French knight named Eranton de Blois. There's no historical certainty about what happened next, but according to the legend, Yolande conspired with one of her father's henchmen, the Comte de Montbar, to get de Blois out of the way, and he did -- via a dagger in the back.
The Abbot of Jedburgh demanded an investigation, but (predictably) nothing came of it. Yolande was engaged to marry King Alexander, and the ceremony took place in the abbey church on November 1, 1285.
Everything was going forward with the typical medieval pomp and solemnity until the door of the church flew open with a bang, and an uninvited guest strode up the aisle, wearing armor and a tattered and bloodstained cloak. When he reached the front of the church, the king said in a furious voice, "Who are you?"
At this point the figured lifted its visor, to reveal the decaying visage of a corpse.
De Montbar collapsed to the floor, writhing, and Yolande recoiled -- because, of course, they both recognized the dead man's face. The specter pointed at Yolande and said, "Ask her. My curse be on you and on her, the curse of the assassin's victim, treacherously ambushed and foully slain. Hear me well, unhappy king. Before three months have passed, they will sing masses for your soul in Jedburgh Abbey and she will be left a widow. She will suffer the hatred of her people and will forever be reminded of her crimes."
Three months turned out to be an underestimate, but not by much. On March 19, 1286, the king rode out after dark to join his wife at Kinghorn in Fifeshire, and the next morning was found at the bottom of a steep, rocky embankment with his neck broken. Pragmatic folks said his horse lost its footing in the dark and threw its rider to his death; the more imaginative said it was the curse being fulfilled. However it was, the whole thing propelled Scotland into chaos. Alexander's granddaughter, Margaret, "Maid of Norway," died on board ship during the crossing to Scotland in 1290, leaving no heir to the throne. The following years of civil war and repeated invasions from England (including the one that ultimately led to the brutal execution of William Wallace) only ended in 1306 with the coronation of Robert the Bruce.
As far as the rest of the "curse," it kind of... didn't happen. There's no indication that Yolande was hated; she returned to France, where she remarried to Arthur II, Duke of Brittany, had six children of whom five reached adulthood, and lived to age 67 (neither of those a bad accomplishment back then). She had received land in Scotland as a dowry for her first marriage and continued to manage it from over the Channel, apparently untroubled by the sordid story that was attached to her name.
But as for Alexander, death didn't bring him any peace. Both his ghost and de Blois's have been seen on the abbey grounds, despite the fact that even the harshest versions of the legend didn't attach anything blameworthy to either one, and the spirits of the two people who were the real bad guys (Yolande and her murderous co-conspirator de Montbar) are nowhere to be found. I guess there's no justice to be had, even in the afterlife.
Anyhow, that's today's creepy story, appropriate given that I'm already seeing Halloween decorations in the stores around here. It makes a good tale even though the great likelihood is that large parts of it were made up after the fact. But if you ever get a chance to visit Jedburgh, keep an eye out for phantoms. A medieval king with a broken neck and a bloodied corpse in armor. Shouldn't be hard to spot.
