Mysterious mosaic
Belle Vue cottage, a detached residence, has been lately been purchased by a gentleman, who, having occasion for some alterations, directed the workmen to excavate some few feet, during which operation the work was impeded a large stone, the gentleman being immediately called to the spot, directed a minute examination, which led to the discovery of an extensive grotto, completely studded with shells in curious devices, most elaborately worked up, extending an immense distance in serpentine walks, alcoves, and lanes, the whole forming one of the most curious and interesting sights that can possibly conceived, and must have been executed by torch light; we understand the proprietor intends shortly to open the whole for exhibition, at small charge for admission.
- a seventeenth- or eighteenth-century rich person's "folly"
- a prehistoric calendar
- a meeting place for "sea witches" (whoever those might be)
- something connected to the Knights Templar
A lunatic is easily recognized. He is a moron who doesn't know the ropes. The moron proves his thesis; he has a logic, however twisted it may be. The lunatic, on the other hand, doesn't concern himself at all with logic; he works by short circuits. For him, everything proves everything else. The lunatic is all idée fixe, and whatever he comes across confirms his lunacy. You can tell him by the liberties he takes with common sense, by his flashes of inspiration, and by the fact that sooner or later he brings up the Templars.
Be that as it may, we still don't know who built the Shell Grotto. There are also extensive shell mosaics that were created by the Romans and the Phoenicians, but the archways in the Rotunda have impressed archaeologists as being more consistent with those used in twelfth-century Gothic cathedrals (although not nearly as large, obviously), and therefore not nearly old enough to be Roman or Phoenician in origin. It seems like the simplest thing to do would be to carbon date one of the shell fragments -- mollusk shells are largely calcium carbonate, so it should be possible -- but the site is under private ownership, and to my knowledge no one has done that yet.
So the Shell Grotto remains mysterious. It certainly represents an enormous amount of skill and dedication, whoever created it; just cutting a tunnel that long through chalk bedrock would take extensive and back-breaking labor, not to mention then hauling over four million shells there and somehow getting them to adhere to the walls in beautiful and flowing artistic patterns. It's open for visits from the public, and next time I'm in England I'd love to check it out. Just another reason to travel to a country I love -- as if I needed another one.

The free speech you disagree with
Thomas Paine said, "He who would make his own liberty secure, must guard even his enemy from oppression; for if he violates this duty he establishes a precedent that will reach to himself."
This principle -- espoused by many leaders of the Enlightenment -- was famously summarized by historian Evelyn Beatrice Hall as "I may disagree with what you say, but I will defend unto death your right to say it." It's a central founding tenet of democracy. We all have voices, and are allowed (within certain well-demarcated boundaries, including prohibitions against threats, hate speech, and fraudulent claims) to use them to voice our own views.
That right has been steadily eroding under the Trump regime.
The situation got markedly worse following the assassination of right-wing agitator Charlie Kirk last week. First, allow me to state up front that I am in no way celebrating Kirk's death. No one deserves to be murdered, period, end of story.
But. The fact remains that Kirk was a thoroughly horrible human being, and his violent death doesn't cleanse him of the odium of things he himself said. Here's a small sampler:
- "[The biblical injunction to stone gay people to death] is God's perfect law when it comes to sexual matters."
- "[Black people] are coming out, and they're saying, 'I'm only here because of affirmative action.' Yeah, we know. You do not have the brain processing power to otherwise be taken really seriously. You had to go steal a white person's slot to go be taken somewhat seriously."
- "We made a huge mistake when we passed the Civil Rights Act in the mid-1960s."
- "I can't stand the word empathy, actually. I think empathy is a made up new age term that does a lot of damage."
- "[Transgender people] are an abomination to God."

Mechanical brain transplant
My first thought was, "Haven't you people ever watched a science fiction movie?" This feeling may have been enhanced by the fact that just a couple of days ago I watched the Doctor Who episode "The End of the World," wherein the Doctor and his companion are damn near killed (along with everyone else on a space station) when a saboteur makes the shields malfunction using little scuttling metallic bugs.
The creator of the Neanderthal brain bits is Alysson Muotri, geneticist at the University of California - San Diego's School of Medicine. He and his team isolated genes that belonged to our closest cousins, Homo sapiens neanderthalensis, and transferred them into stem cells. Then, they allowed the cells to grow into proto-brains to see what sorts of connections would form.
Muotri says, "We're trying to recreate Neanderthal minds." So far, they've noticed an abnormally low number of synapses (as compared to modern humans), and have speculated that this may indicate a lower capacity for sophisticated social behavior.
But Muotri and his team are going one step further. They are taking proto-brains (he calls them "organoids") with no Neanderthal genes, and wiring them and his "neanderthalized" versions into robots, to make comparisons about how they learn. Simon Fisher, a geneticist for the Department of Psycholinguistics at the Max Planck Institute, said, "It's kind of wild. It's creative science."
That it is.
I have to admit there's a cool aspect to this. I've always wondered about the Neanderthals. During the peak of their population, they actually had a brain capacity larger than modern humans. They clearly had culture -- they ceremonially buried their dead, probably had language (as they had the same variant of the "linguistic gene" FOXP2 that we do), and may have even made music, to judge by what appears to be a piece of a 43,000 bone flute that was found in Slovenia.
All that said, I'm not sure how smart it would be to stick a Neanderthal brain inside a metallic crab. If this was a science fiction movie, the next thing that happened would be that Muotri would be in his lab late at night working with his Crab Cavemen, and he'd turn his back and they'd swarm him, and the next morning all that would be found is his skeleton, minus his femur, which would have been turned into a clarinet.
Okay, I know I'm probably overreacting here. But it must be admitted that our track record of thinking through our decisions is not exactly unblemished. Muotri assures us that these little "organoids" have no blood supply and therefore no potential for developing into an actual brain, but still. I hope he knows what he's doing. As for me, I'm going to go watch Doctor Who.
Let's see, what's the next episode? "Dalek." *reads description* "A superpowerful mutant intelligence controlling a mechanical killing device goes on a rampage and attempts to destroy humanity."
Um, never mind. *switches channel to Looney Tunes*

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.
