Andy Brewer is an audio engineer and composer. He was playing around with pink noise, what we lay people would call static or just noise, on an equalizer and found he could extract musical notes from it with a little work. Could he play a song using just those notes? It would be a song without a voice or musical instrument. Yes, he could, although it was a lot of work. You wouldn't be able to do this if you didn't know a lot about music already. This song is technically "electronic music," and it's what a synthesizer (which is a musical instrument) does, although Brewer didn't use a synthesizer; just an equalizer. 

Music buffs in the comments said this is an additive synthesizer or a subtractive synthesizer. I don't know which is correct, but it took many people many years to develop the music synthesizer, while Brewer started from almost nothing and figured it out on his own. I'm impressed. The song is quite pleasant, too. -via kottke 

The world has always known people who just do not want to be told what to do. Sometimes it can be hard to draw the line between rebellion and mental illness, especially when you throw in exacerbating factors. Frances Farmer was a beautiful woman who became a movie star in the 1930s. Naturally rebellious, she could not abide the Hollywood studio system that had her under contract. They told her what to wear, who to talk to, and even who to marry. They prescribed amphetamines to keep her weight under control. Eventually, it became too much. 

Farmer was arrested several times in the 1940s for various offenses, in which she resisted arrest, even fighting the cops. She back talked a judge in a court exchange that reporters found hilarious. To keep her out of jail, Farmer was sent to a series of mental institutions, where she underwent electroconvulsive therapy, and she came out with stories of neglect, rape, and abuse that were common to such institutions at the time. She still made comebacks, in film, in television, and then on stage, but she never lost her rebellious streak. Read about the crimes of Frances Farmer at Messy Nessy Chic.

Crazy cat lady that I am, I have a small part of my garden dedicated to catnip (and strawberries; they seem to get along well). The cats like it, and it makes my home the cool place for neighborhood kitties to hang out. But is there any evolutionary reason for cats to go crazy for catnip? Research has isolated the exact compounds that intoxicate cats, nepetalactone in catnip, and nepetalactol in silver vine, another popular cat attractant. 

Not only have scientists found how these compounds affect cats, but also why. It's an adaptive feature of their evolution! Cats rarely pay any attention to plants, but the cats who went for catnip or silver vine were more likely to survive and reproduce millions of years ago until a catnip attraction became quite common among several cat species on the African savannah. This TED-Ed video explains why with some charming cat animation, although you might not like one of the experiments that led to this knowledge. -via Geeks Are Sexy 

Dough Lisa is a bread artist whose sourdough work has become a viral sensation. Pictured above is one of her most recent creations: a groovy-looking loaf with woven threads of tie-dye dough covered with an outer black shell.

You can see her full process video here. It has eleven colors inside. The results when she cuts it open are extraordinary. It's like a human brain that's been drenched in the art of the 1970s.

Cinematographer Jamie McPherson took a crew to northern Canada to shoot footage of narwhals for the Netflix documentary series Our Planet in 2017. In his account of the trip, we will learn more about narwhals than about polar bears, but it was the bear that made the project dramatic. Narwhals gather at the edge of the ice in spring, waiting for the ice to crack so they can reach fishings grounds that were closed to them all winter. The crew got aerial footage in a helicopter, and underwater footage from a specialized crew, but they needed footage from the ground, meaning the ice, to round out the collection. For safety, they were using a boat.

They spotted the polar bear asleep as they prepared to set off in the boat. When the bear woke up and started running toward them, one crew member fired a warning shot to scare it off, but found the gun didn't work. They got the boat into the water in a hurry, planning to put some distance between themselves and the bear. But the boat motor didn't work, either. Since McPherson is telling the story now, you know he survived, and you can read his account at DiscoverWildlife. The moral of the story is to check all your equipment before going on an Arctic adventure. -via Damn Interesting 

The story of Lover's Lane is an urban myth about a couple who goes parking and narrowly escapes a horrible death. What we called "parking" is the custom of young people in a car finding a secluded space to canoodle away from prying eyes, and many towns have at least one road that is famous for such activities nicknamed Lover's Lane. The first part of this video explores the history of how parking itself became a thing. 

Then at about five minutes in, we learn about the very real crimes that may have sparked the urban legend. Or did the urban legend inspire the crimes? Since we don't really know how far back the legend goes, it's not quit clear. But for someone who wants to kill and get away with it, teenagers in a car on a lonely road present a tantalizing opportunity. 

The third section of the video goes into how these crimes and the Lover's Lane legend influenced the modern horror film. That seems only natural, since the target audience for these movies are young people who have the world in the palm of their hands, until they don't.

The soft, rolling melody of "Fields of Gold" is among British singer Sting's most famous songs. Here's a cover performance by The Petersens, a family band that is based in Bronson, Missouri. With a fiddle, a mandolin, a banjor, a gutiar, a double bass, and a dobro, this group offers bluegrass, folk, and traditional hymns.

The Petersens also present a folk version of "Dreams" by the Cranberries that is as uplifting as when Dolores O'Riordan first sang it.

On June 5, 1968, presidential candidate Robert F. Kennedy made his way through a crowd at the Ambassador Hotel in Los Angeles after winning the California primary. He was shaking hands as a bullet tore through him, and he was dead the next day. The last hand he shook was that of 17-year-old hotel busboy Juan Romero. Romero crouched down beside Kennedy, and became a subject in the photograph that everyone remembers from that day.

That photo brought Romero celebrity, but he had a hard time dealing with it. He was only a teenager, and was wracked with guilt. What if he hadn't gone for a handshake from Kennedy? Would the bullet have missed him? It didn't help that other people were thinking the same thing, and let him know about it. Romero lived with the "what ifs" for the next fifty years, until his death in 2018. But he eventually made peace with history, and was even able to talk about it. Read Romero's account of what happened that day, and how he dealt with the aftermath at Utterly Interesting.

Bowling balls can be quite heavy. The United States Bowling Congress requires that they weigh between 10 and 16 pounds. That can be too much for people with limited hand strength or finger coordination, so it's fortunate that the governing organization for that sport accepts adaptive balls.

These balls made by differentcompanies have retractable handles. As soon as the player releases the ball, the handle snaps inside. The ball can then roll down the lane with minimal distruption from the site of the handle.

William Pool of Bolivar, Missouri passed away at the age of 101. He enlisted in the US Army in 1941 and served throughout World War II, including participating in the Battle of the Bulge and the long Allied offensive that ended in Austria.

Pool was a member of the Sons of Union Veterans of the Civil War, a fraternal organization that honors ancestors who fought for that side of the Civil War. In the 161 years since the conclusion of that war, the organization is in the hands of later descendants, but Pool's father was, literally, a Civil War soldier.

KY3 News reports that Pool's father, Charles Parker Pool, was born in 1844. He served in the 6th West Virginia Volunteer Infantry Regiment. He was 80 years old when his son, William Pool, was born in January of 1925.

Who was the last son of a Confederate veteran? What was Calvin Robertson Crane, who passed away in 2019 at the age of 102. Like Pool, Crane was a combat veteran of World War II.

When a cool science fiction weapon sticks around for half a century and gathers more and more fans and more fiction, there will be people who put way too much thought into it. The lightsabers from Star Wars were born out of a cool special effect, but now everyone wants one, or at least wants to understand them.   

What happens if you drop a lightsaber? Specifically, what happens if you drop one vertically, business end first, into the ground. Would it keep burning its way through the earth indefinitely? In the Star Wars universe, no, because there's a safety feature that disables the blade when it's not held. But there have been depictions of Jedi throwing lightsabers, so this feature apparently can be disabled. So what would happen in the real world? Rocket Riley goes through all the ways a lightsaber would act on earth, if there were such a thing. -via Laughing Squid 

Around the turn of the 20th century, about two million children in America younger than 15 were full-time workers. Some were a lot younger than 15, and they worked dangerous jobs, sometimes 12 hours a day or more, just like their parents. The photo above shows two boys at a cotton mill in Georgia. An adult working this machine would have their feet on the floor, but children were assigned such work because they had smaller hands and arms that could manage the machines better. And of course, they weren't paid much. 

The National Child Labor Committee was formed in 1907, and they commissioned sociologist and photographer Lewis Hine to document the practice in 1908. Hine knew that nothing would move popular opinion like a photograph. Factory overseers knew it, too. He had to sneak into workplaces, pretending to be an inspector or a Bible salesman to gain access, and he often took notes with his hands in his pockets to avoid detection. Hine's photos taken between 1909 and 1911 shocked the country, and led directly to the first federal child labor law in 1916. See samples of Hine's child labor photographs that led to changes in the system at Smithsonian. 

First, you watch the video because cat, but wow, what a fine looking cat. Then you are impressed by her behavior. Rory (short for Aurora Borealis) is a four-year-old Bengal cat with nice markings and stunning aqua blue eyes. But Rory is more than her looks. She understands the English language better than you can imagine! That's because her person has so many delightful activities and rewards that go with those words. Or is Rory just a magical being trapped in a pretty cat body? She responds to a variety of commands, and she talks back, too. You have to wonder whether she's giving her own commands when she speaks. And since we don't understand, who are the real dumb animals here? 

Rory takes that in stride. She has her mom wrapped around her little paw, and she's living a good life, chasing a plastic propellor around the house and impressing the internet. See more of Rory at her Instagram page. 

Sometimes imaginative play can go too far.

Andy Sahlstrom, an artist in Brooklyn, calls his site "Kids Toys, Adult Issues." At Shampoooty, he offers custom toys that parody the Little Tikes aesthetics marketed toward preschoolers. But despite their small sizes, pastel colors, and gently rounded contours, they're made for adults with a very dark sense of humor.

Pressure News Media wrote that Sahlstrom was struggling with a breakup when he went into a workshop to work through his pain. His first piece was the Cozy Hearse.

Sahlstrom's creativity has met with...resistance. Pressure News Media notes that the artist experienced legal responses from the brands that he parodies.

A case study from Brazil offers a tantalizing possibility for treating dementia with magic mushrooms. A woman in her 80s suffering from advanced Alzheimer's disease had been incontinent for five years, did not initiate conversation, and only spoke in monosyllables. Her medical guardian gave permission for a dose of hallucinogenic mushrooms. She was given five grams of mushrooms containing psilocybin, which is a massive dose, much more than in other such experiments. 

After sleeping for 19 hours, the patient woke and began talking to herself. Over the next few days, she began speaking to others in complete sentences, controlled her bladder, and was even able to dress herself! The effects were lasting, too. She was given a second three-gram dose a month later, and showed even more improvement. The data from this one patient is a little sparse, as they didn't do any brain scans before and after treatment, but it may lead to more such experimentation. Read more about the magic mushroom treatment at Science Alert.
