A volcanic eruption may have led to the spread of the Black Death

The infamous Black Death — a pandemic that killed as many as one third to one half of Europeans within just a few years — may have been aided in its devastation by an unknown volcanic eruption. That’s the hypothesis presented in research published December 4 in Communications Earth & Environment, which argues that the eruption triggered several seasons of climate instability and crop failures. That instability, in turn, forced several Italian states to import grain stores from new sources—specifically, from regions surrounding the Black Sea. Riding along on those grain stores, the researchers posit, were fleas infected with Yersinia pestis, the bacterium that causes the plague. (via Scientific American)

Research shows cold pizza might be better for you than hot pizza

Your first thought on hearing this is probably “Why? Why is leftover pizza healthier for me?” And the answer has to do with what happens when you cool the delicious crust. When you cool a pizza to below 40 degrees Fahrenheit, some of the starches in the dough will start to mingle together to form these long chains called resistant starches. They resist digestion, and another word for a carbohydrate that resists digestion is fiber! And even if you reheat the pizza, the chains stay intact, so your body doesn’t break them down to sugar. They mostly pass through. This could help reduce blood sugar spikes for people with diabetes or people who just need more fiber for a healthier gut. And this seems to work for a lot of starches, like rice, pasta, potatoes—even beans and lentils. Heating then cooling the starch changes its properties. It’s like tempering chocolate or forging a stronger steel. (via Scientific American)

How playing Santa Claus at Macy’s changed his life

Santa Claus was nursing a beer at an uptown dive bar. The neighborhood was gentrifying, and management seemed eager to accommodate—there was scented soap in the bathroom and twenty-two-dollar lobster rolls. But the place couldn’t outrun the regulars. They drank tumblers of Irish whiskey filled to the brim, illicit pours they secured with ten-dollar tips to a curvy Dominican bartender. Santa — Billy — was fiftyish, with a modest gut, gray hair, a lustrous beard, and a caddish gaze that followed the bartender up and down the rail. He was dressed in sweatpants and a T-shirt. For the price of three beers, he told me his story. As a young man, Billy had come to New York to be an actor. These were bad years, shameful even. He lost his job. He lost his wife. Lost touch with his young son too. He was overweight and undershaved. A friend had a weird idea: Billy could try playing Santa Claus at Macy’s. And that’s what Billy did. (via Esquire)

It’s illegal to sell chewing gum in Singapore and has been since 1992

The sale of chewing gum in Singapore has been illegal since 1992. Some motivations for the ban included stopping the placement of used chewing gum in inappropriate and costly places, such as the sensors of subway doors, inside lock cylinders, and on elevator buttons. Chewing gum was causing maintenance problems in high-rise public-housing apartments, with vandals disposing of spent gum in mailboxes, inside keyholes, and on lift buttons. Gum stuck on the seats of public buses was also considered a problem. Since 2004, an exception has existed for therapeutic, dental, and nicotine chewing gum, which can be bought from a doctor or registered pharmacist. It is not illegal to chew gum in Singapore, but it is against the law to import it and sell it, apart from the aforementioned exceptions. According to a BBC News article, it is legal for a traveler to bring in a small amount of chewing gum for personal use, and there is a fine for spitting the gum out in an inappropriate place.   (via Wikipedia)

That time Abraham Lincoln had a terrible blind date

In 1838, 29-year-old Illinois state representative Abraham Lincoln went on a pseudo blind date set up by a friend. The date wasn’t entirely blind — Lincoln had seen the sister some years before, and said she seemed to be “intelligent and agreeable.” But things quickly went from great to uncomfortable when Mary Owens did not look as Abe had remembered her. “I knew she was oversize, but she now appeared a fair match for Falstaff,” he wrote. “When I beheld her, I could not for my life avoid thinking of my mother; and this, not from withered features — for her skin was too full of fat to permit of its contracting into wrinkles — but from her want of teeth, weather-beaten appearance in general.” Despite this initial impression, Lincoln seems to have changed his mind later, because he proposed marriage — and Owens refused. Twice. (via Mental Floss)

If you have an allergy to pork scientists say you are probably also allergic to cats

A pork allergy is an adverse immune response after consuming pork and its byproducts. It is also called pork-cat syndrome because most pork allergies are related to cat allergies. The reason that some cat-sensitized individuals are susceptible to pork allergies is that some individuals are not only allergic to the cat dander, but are also allergic to a protein found in cats called albumin.  Albumin is also found in meat from pigs and other animals. Other causes of pork allergy are unknown. Undercooked pork or dried pork products tend to cause more reactions than well-cooked pork. Symptoms include urticaria (hives), pork allergy rash, and inflammation of the skin; gastrointestinal symptoms including nausea, vomiting, and stomach cramps; runny or stuffy nose; mild fever; wheezing and difficulty breathing; and in rare cases, anaphylaxis.

A startup says it has a process for turning mercury into gold

A fusion energy start-up claims to have solved the millennia-old challenge of how to turn other metals into gold. Chrysopoeia, commonly known as alchemy, has been pursued by civilisations as far back as ancient Egypt. Now San Francisco-based Marathon Fusion, a start-up focused on using nuclear fusion to generate power, has said the same process could be used to produce gold from mercury. In an academic paper published last week, Marathon proposes that neutrons released in fusion reactions could be used to produce gold through a process known as nuclear transmutation. The paper has not yet been peer-reviewed but has had a positive reception from some experts in the field. “On paper it looks great and everyone so far that I talk to remains intrigued and excited,” Dr Ahmed Diallo, a plasma physicist at the US Department of Energy’s national laboratory at Princeton who has read the study, told the Financial Times.

A raccon broke into a liquor store and was found passed out face down in the bathroom

A drunken raccoon was found asleep amid its work at the ABC liquor store in Ashland, Virginia, a trail of broken bottles and spilled booze leading to its resting place by the staff toilet. “Officer Martin safely secured our masked bandit and transported him back to the shelter to sober up before questioning,” Hanover County Animal Protection and Shelter posted to social media. “After a few hours of sleep and zero signs of injury (other than maybe a hangover and poor life choices), he was safely released back to the wild, hopefully having learned that breaking and entering is not the answer. … Just another day in the life at Hanover Animal Protection!” The Associated Press talked to the animal control officer who responded to the call and found the plastered procyonid. “I personally like raccoons,” she told them, “He fell through one of the ceiling tiles and went on a full-blown rampage, drinking everything.” (via Boing Boing)

Self-driving cars are an unambiguous social good

Before we get started, let’s agree that Elon Musk’s promises about full self-driving on the Tesla have been figments of his ketamine-addled imagination, if not an outright fraud. Musk first promised FSD in 2016, almost a full decade ago, and it is barely any closer now. His then-Twitter account almost 10 years ago was full of hype about features like “Summon,” where a Tesla owner across the city could click a button in the app and their car would autonomously leave the garage and drive across town, something that still hasn’t arrived. Is it because Musk refuses to use LiDAR, which literally every other self-driving car maker uses, and has stuck to trying to get cameras and algorithms to do it alone? Possibly. Regardless, the fact is that a Tesla still has problems making it onto highway exits or detecting when lanes are closed, and it routinely cuts other drivers off. In other words, Tesla self-driving is a pale imitation of what Musk has been promising for years, to the point where there are multiple class-action lawsuits about it.

That said, however, I think there’s ample evidence that self-driving cars — even the somewhat flawed ones we have now — are an unambiguous social good. They are so much better than cars driven by human beings that it doesn’t seem fair to even compare them. It’s like arguing that toasters are better than jamming a piece of bread on a stick and holding it over a fire, or that anaesthesia is better than telling someone to bite a bullet before you operate. If it were possible to flick a switch and make all cars self-driving, it would be incumbent on us to flick that switch as quickly as possible. To get a sense of why I believe this is the case, Waymo — Google’s self-driving car startup — recently released statistics on the accident rate of its cars, of which there are more than 2,500 in five cities. As of June this year, Waymo cars had driven almost 100 million miles and had 90 percent fewer crashes causing serious injury, and 90 percent fewer incidents involving pedestrians (Tesla also reports accidents but with much less detail).

Mick Jagger was a pioneer in streaming video on the internet

In the late 1990s, when most people just about had an email address and the smartphone with even one G, never mind five of them, was just a twinkle in a mad inventor’s eye, the internet was still regarded by many as the preserve of the nerd. Most of the record industry either treated it as an irrelevance or, with the advent of Napster and other streaming services a few years later, a threat. But Jagger was an early adopter, or at least he was someone who spotted the internet’s potential while others retained suspicion. Jagger is also a cricket nut. So when he discovered that nobody was planning to broadcast the Akai-Singer Champions Trophy — a relatively minor one-day tournament in December 1997, featuring England, Pakistan, India and West Indies — these two interests converged. So he formed a company and broadcast it himself. (via the NYT)

Some scholars believe the Wizard of Oz is an allegory for the move to a gold standard in 1873

In a 1964 article, educator and historian Henry Littlefield outlined an allegory in the book of the late-19th-century debate regarding monetary policy. According to this view, for instance, the Yellow Brick Road represents the gold standard, and the Silver Shoes (Ruby slippers in the 1939 film version) represent the Silverites’ wish to maintain convertibility under a sixteen to one ratio. Hugh Rockoff suggested in 1990 that the novel was an allegory about the demonetization of silver in 1873, and that the City of Oz earns its name from the abbreviation of ounces “Oz” in which gold and silver are measured. The cyclone that carried Dorothy to the Land of Oz represents the economic and political upheaval, the yellow brick road stands for the gold standard, and the silver shoes Dorothy inherits from the Wicked Witch of the East represents the pro-silver movement. When Dorothy is taken to the Emerald Palace before her audience with the Wizard she is led through seven passages and up three flights of stairs, a subtle reference to the Coinage Act of 1873.

Fun trick: Try to get a German person to say the word squirrel

If you are bored and there are German-speaking people around, try to get them to say the English word “squirrel.” They may try valiantly to do so, but most will be unable — for the simple reason that the word contains a number of sounds that either don’t exist in the German language or never appear in that order. The soft “w” sound that the “uir” in squirrel involves, for example, doesn’t exist — w is exclusively pronounced as a hard V (conversely, the letter “v” is pronounced like an F, so Volkswagen sounds like Folksvagen). There are YouTube videos of German people trying to say squirrel and failing hilariously.

I’ve come across a number of stories over the years about how the word squirrel was used during World War II as a “shibboleth” or a word that could reveal whether someone was a German spy, since the vast majority of Germans would be unable to say it properly. So supposedly English speakers would try to work the word into a conversation to see if the suspected spy could say it. According to one report I came across, this story was repeated by a former World War II warrant officer in the US Army, but I’ve been unable to prove that it’s true (Top Gear host Jeremy Clarkson may have started this).

So far, I’ve been unable to confirm whether the story is true or not. If you know of someone who can confirm it, please let me know! Interestingly enough, the German word for the animal that English speakers call a squirrel is Eichhörnchen, which is extremely difficult for English speakers to say, as this video proves. So perhaps both sides during World War II could have used their language’s term for the animal as a secret spy test!

Lead poisoning may have led to a generation of serial killers

The Pacific Northwest is known for five things: lumber, aircraft, tech, coffee, and crime. What might account for the abrupt rise and equally abrupt fall, between the nineteen-sixties and the turn of the century, of the “golden age” of serial killing? And why were so many of these brutes cradled in a crescent of psychopathy around Seattle’s Puget Sound? Fraser thinks the master key is to be found in the fact that the area south and southwest of Seattle was home to massive ore-processing facilities, and her subjects were reared in their murky shadows. “Spare some string for the smelters and smoke plumes,” she writes of her crazy wall, “those insidious killers, shades of Hades.” The smelters caused a profusion of heavy metals in the air and water, and toxins such as lead and arsenic were found in staggering concentrations in the blood of Tacoma’s children. Some were merely dulled, or delinquent; a few became tabloid monsters. (via the New Yorker)

Spotify changed its randomness algorithm to make it less random but it feels more random

Spotify’s first iteration of its shuffle feature was dictated by a decades-old algorithm that generated unbiased randomness from a finite sequence of elements. Breathtakingly efficient, the Fisher-Yates shuffle was employed by Spotify to dismantle user playlists and reassemble them into new, unpredictable orders. From the developers’ perspective, the task of creating this feature was masterfully accomplished with just a few lines of code. From early users’ perspective, shuffle was a travesty. This discrepancy was bewildering for both parties, but mainly for developers, who had delivered a mathematically perfect version of randomness. Perfection turned out to be the problem. The algorithm captured a Platonic ideal of randomness instead of one compatible with the human mind. We presume that randomness must always be chaotic. However, as randomness is unpredictable, it will at times give the impression of order. (via the FT)
