Throwing a cable across a ravine is easier than building a bridge. Actually, throwing a cable across is the first step to building a bridge, but sometimes the project stops there, because people can cross with just a cable if they are brave enough. Slovenia has several manual cable cars strung across some of its more inaccessible ravines, but Tom Scott found only one that is regularly maintained. When you see it, you'll have your doubts. But Tom watched other people use it, and was game to demonstrate it for us. There's no way on earth you'd get me in that thing, even if I were being chased by some bad guys out of an Indiana Jones movie, and I grew up in the land of rickety swinging footbridges. Would you ride a rusty 70-year-old zipline? If heights make you queasy, be warned that they do show images of what Tom is crossing over.

From the early days of photography, here's a story of a torture that became a badge of honor. Born in 1799, Captain Jonathan W. Walker was an avid abolitionist. He worked with the Underground Railroad, and helped those who escaped slavery settle in Mexico. But in 1844, he was on a boat taking seven escapees to the West Indies when they got into trouble and were rescued by a ship with a pro-slavery crew. Walker was arrested, and a US Marshall branded his right hand with "SS," which stood for "slave stealer." He was jailed in Florida for eleven months.

The incident didn't slow Walker down at all, and he continued his abolitionist work lecturing and arranging for escapes after his bail was paid by an abolitionist group. Not long after, he commissioned a photograph to be made of his branded right hand. The image, however, is reversed and appears to be his left hand- notice that the Ss are backward.

At its most basic level, cancer is when our own cells decide to grow out of control. Yes, it's much more malignant than that sounds. Your body will recognize and fight the danger, but if it gets bad enough, your immune system will need outside help.

In this video, Kurzgesagt describes the immune system's battle against cancer in an analogy of a city and its emergency systems going up against a chaotic gang of dangerous troublemakers, some of them with malevolent supernatural power. That makes it easier to understand, but I also see another analogy here in the story of drug-resistant bacteria. If you spread antibiotics out too widely, such as treating entire livestock herds before any infection is present, or using antimicrobial soaps, you risk allowing some surviving superbugs to evolve and flourish. So who wins the battle? It's hard to say, because this can all go on without us ever knowing it. But concerning the cancers that become bad enough for us to detect them, we are learning more and more about building more powerful weapons against these malignant cells all the time.

Archaeologists studying an excavation in Nördlingen, Germany, have uncovered a sword in a grave that contained a man, a woman, and a young boy. It was among other weapons and artifacts included in the burial, which is considered around 3,000 years old. But the sword has been uniquely preserved, and looks only a few years old. The sword is bronze, made by the applied bronze casting method, which is labor intensive and requires quite a bit of skill. Scientists don't know where it was made. But you might wonder how it was preserved so long in such a pristine condition. It's all about the cuprous salts.

3/
Copper-based artifacts create exceptional preservational circumstances because copper salts ward off microbes and copper doesn't corrode the same way that iron does. This can often lead to artifacts looking practically brand new, like this 400 year old chafing dish fragment. pic.twitter.com/BYTzX4yqrZ

You can read more about the chemistry involved in the Twitter thread. We don't know if the sword has been removed from the site yet, but there's a possibility that whoever lifted it from the rock after all this time is now the rightwise king born of somewhere.  -via Metafilter

The ESA spacecraft carrying the James Webb Space Telescope launched on Christmas morning 2021 from the Centre Spatial Guyanais in the city of Kourou in French Guiana. You may wonder what a European spaceport is doing in South America. The French space agency CNES was established in 1961 with a spaceport in Algeria, which was then part of the French empire. Algeria fought and won their independence in 1962, and the space agency had to start all over. They selected French Guiana because it was already a French territory and had good conditions for space launches. They built Kourou specifically for the space center, evicting around 600 villagers to do so.

But French Guiana, and particularly the Salvation Islands off its coast, has a sordid history. Until the mid-20th century, it was France's penal colony. After slavery was abolished in France, the country sent prisoners to South America to serve out their sentences- and to harvest crops and build infrastructure. Of the 80,000 or so prisoners sent to French Guiana, the majority never made it back to France even after their sentences were up. This was the setting of the book and movie Papillon. Read about the space centre built overtop a notorious penal colony at Supercluster. -via Smithsonian

Fathers Day would not be complete without Darth Vader jokes. Star Wars fans of a certain age still haven't gotten over the twist in The Empire Strikes Back, the one that turned a single space adventure into an epic family saga. Too bad that was the peak of the series. (Dragging Leia into the family didn't happen until The Return of the Jedi, and never made much sense anyway. I think Lucas just did that solely so we wouldn't feel bad for the hero who didn't get the girl in the end. But I digress.) You'll have to recall what was said during that battle, because this video only has grunts, but I suspect you know what happened.

In this holiday vignette from LEGO, we finally see what caused Darth Vader to do a sudden turnaround and decide his loyalties were with his son instead of the Emperor. A simple gift causes Vader to think about all the things that might have been if he had spent his time as a dad instead of a Sith Lord. Send this post to your Dad to give him a smile for Fathers Day. -via Geeks Are Sexy

The 2009 Disney Princess movie The Princess and the Frog is loosely based on the Grimm's fairy tale The Frog Prince. But the character of Tiana, the "princess," was inspired by a real person. Disney wanted to place a fairy tale in the United States with a Black protagonist, and after a lot of changes to the project, focused on the real-life story of Leah Chase of New Orleans, “the Queen of Creole Cuisine.” The parts of the story that were not from The Frog Prince are Chase's.

According to Leah Chase's daughter Stella Chase, it was always her mother's dream to open a restaurant. She fell in love with a New Orleans musician whose parents owned a po-boy stand. They married, and Chase worked in the kitchen, honing the cooking skills she brought from her large family. When she and her husband Edgar inherited the restaurant, she expanded it and introduced an extensive menu of Creole cuisine. Now named Dooky Chase's Restaurant, the establishment became a meeting place and a refuge during the Civil Rights Movement. Read about Leah Chase and how her legacy figures into The Princess and the Frog at Gizmodo.

The European Space Agency's Mars Express spacecraft has been mapping Mars for twenty years now. In honor of the occasion, the space agency has released a global color mosaic of the red planet that's more than just red. The High Resolution Stereo Camera (HRSC) science team has stitched together 90 images taken from 4000 to 10,000 kilometers above the surface to show the features of Mars in the clearest detail yet.

Mars look pretty much all red in the images we've seen before, because the planet has so much iron oxide. That's what we call rust. But Mars also has more dense, dark bluish-gray sand made of volcanic basalt that formed enormous dunes across the center of the planet from this angle. It also has clay and sulphates that formed from the contact of water with volcanic materials that show up as lighter colors. Read more about the image and how it was made at the German Aerospace Center.  -via Kottke

When you think of Nevada's Clown Motel, you think of it as one of the few surviving examples of American tourist kitsch. Or you may know its reputation for being haunted. How could you think otherwise, when you are surrounded by clowns? There are 2,000 of them in the lobby alone! But if you are staying overnight in the town of Tonopah, you won't have anything else to do but learn some of its history, and that can be rather frightening.

Tonopah was a silver mining boom town that sprung up out of nothing around 1900, with about 3,000 people. But in 1905, the miners began dying quickly and horrifically from a malady that made their necks swell up and their bodies turn black. This "Death Harvest" killed so many men that quite a few other miners fled the town. Then in 1911, a fire in the mine killed another 17 workers. One of them was Clarence David, who collected clowns. His children grew up and opened the Clown Motel in 1985. Tonopah's cemetery is right next to the Clown Motel, and holds around 300 graves dated between 1901 and 1911. Those buried there include victims of the Death Harvest, the mine fire, childhood disease, and murder. Read about the gruesome history of Tonopah and the Clown Hotel at New Lines Magazine.

Guy tries to break into hotel room while owner is there
by u/OnyxUnix in nope

A woman at the Holiday Inn in San Jose, California, ignored a knock on her door. Not long afterward, she saw a lock monkey snake its way into her room. She called the front desk and then recorded the break-in attempt. Hotel staff came and found a man and a woman who said they were looking for a friend. The couple got away before police arrived. The would-be intruders were obviously looking to rob a supposedly unoccupied room, since they knocked earlier to see if anyone was there. But it could have gone bad if she had confronted them herself. Here is the news report.



Yeah, I don't think switching to Airbnb would be any safer. But there are travel aids you can get that will block a door opening while you are in a hotel room. Something to think about. -via reddit

I know a guy from the Gambia, which is a small country surrounded on three sides by Senegal. The Gambia consists of both sides of the Gambia River down to the Atlantic Ocean. I asked him what "Gambia" means. He said, "River." I couldn't help but laugh. @Foone once mused about these confounding names that just happen when translated into other languages as they would apply to a potential universal translator, the kind they use in the Star Trek Universe. Aliens would think us mad.

Have you ever thought about what archaeologists 1,000 years from now will think when they dig up artifacts of our lives? If civilization, or even mankind itself, can hold out that long, they may be quite confused. Imagine that they dug up a museum and dated the structure to the 21st century. The museum holds artifacts dating to, say, 1,000 BCE, but will the future archaeologists know that? It's happened already that archaeologists find collections of artifacts that are much older than their location would indicate. But one ancient collection stands out because it was a real museum with even more ancient artifacts properly labeled and dated. And it was run by a woman.

Ennigaldi-Nanna was a priestess and a princess of the Neo-Babylonian Empire. She was also an archaeologist and a museum curator, establishing her museum of artifacts around 530 BCE in Ur (modern Iraq). Her displays dated back as far as 2,000 BCE! The museum was discovered in 1925, and has yielded a treasure trove of ancient information. Ennigaldi, who was way ahead of her time, labeled her finds in three languages, including Sumerian, which modern language experts can translate. After the collapse of the Sumerian kingdom, the museum was lost and the practice of labeling artifacts fell out of use for another couple of thousand years. Read about Ennigaldi-Nanna's unique museum at Messy Nessy Chic.

Nothing will clear a room of cats faster than a vacuum cleaner. They are large, mysterious, and worst of all, they make an infernal noise. While there are a few outlying exceptions, cats hate vacuum cleaners. Except Roombas, because Roombas don't make that much noise and they are fun to ride around on.

Simon's Cat is a typical cat, and hates the big, noisy vacuum cleaner. So does the kitten. In this video, they team up together to defeat the enemy. It's nice to see them getting along after all these years of jealousy and spite. And it's nice to have a Simon Tofield video in color!

Acronyms are handy for making long names easier to write, like SETI or NASA. There are so many organizations, facilities, and projects in the world of space exploration that acronyms are everywhere, and making them easy to pronounce and remember is important. But some groups go out of their way to come up with a clever acronym that strains credulity. Glen Petitpas collected these into a master list you may find amusing. Some examples:    

ABRACADABRA stands for A Broadband/Resonant Approach to Cosmic Axion Detection with an Amplifying B-field Ring Apparatus. You get the feeling they could have explained this more simply.

ARMPIT stands for ASKAP Rotation Measure and Polarisation InvestigaTion. Not only is that forced with the T, it's an acronym within an acronym (ASKAP is the Australian Square Kilometer Array Pathfinder).

FIREFLY somehow means Fitting IteRativEly For Likelihood analYsis. They had to go really weird to get that one to work.

GADZOOKS! is for Gadolinium Antineutrino Detector Zealously Outperforming Old Kamiokande, Super! The exclamation point is crucial for some reason.  

GANDALF was created from Gas AND Absorption Line Fitting algorithm.

PEPSI means Potsdam Echelle Polarimetric and Spectroscopic Instrument.

SHIT stands for Super Huge Interferometric Telescope.

My favorite is WISEASS, which is the Weizmann Institute of Science Experimental Astrophysics Spectroscopy System. It's not forced at all, and I'll always remember it.

There are a lot more, and you will probably find funnier ones in there somewhere. The list is called Dumb Or Overly Forced Astronomical Acronyms Site, which of course lends itself to the acronym DOOFAAS. -via Kottke

Cincinnati, Ohio, has always had beer breweries, but in the 1840s, there was an influx of German immigrants who brought lager with them, while existing breweries specialized in port or ale. They aged their lager at cooler temperatures. To achieve the required conditions, they built huge facilities underneath the surface of the city, which got larger and larger as the demand for their product increased. But it wasn't a perfect system, and innovations had to be made over time to make them safe- not from collapse, because they are pretty strong, but from carbon dioxide and ammonia, in addition to industrial accidents. The brewers dealt with all that, but they couldn't withstand the forces of discrimination against German descendants that came with World War I and with Prohibition that soon followed. These underground factories, warehouses, and tunnels are now close to 200 years old, and mostly empty. But Cincinnati is starting to regain its reputation for beer. -via Laughing Squid
