Alejandro Zuluaga and Andrea Palacio packed up their bags and resigned from their corporate jobs to live on their sailboat named Hakuna. The couple rented out the two empty rooms in their house and sold their cars. In a few months, they were able to move in with their dogs to their sailboat and sailed to the Dominican Republic. Forbes interviewed the couple about their unconventional lifestyle. Check the full piece here.

Well, that’s to be expected from a lake growing in the belly of a volcano. A mysterious lake the size of five football fields is growing inside Hawaii’s Kilauea volcano. The deadly waters range from 176 to 185 degrees (80 to 85C), according to the USGS Hawaiian Volcano Observatory, as the Lexington Herald Leader details:
“Globally, only a few volcanic lakes have surface temperatures greater than ... 176 degrees Fahrenheit,” the USGS reported Aug 8.
Why is the water so hot? Experts have not settled on a specific reason.
One factor could be “residual heat” built up in rubble at the base of the site’s pit crater, the USGS says. Another possibility is the nearby gas vents ( fumaroles ) that produce heat in the range of 302 degrees Fahrenheit, the report said.
The lake began forming sometime after a May 2018 eruption caused the floor of Kilauea’s caldera to collapse, leaving “a hole nearly as deep as One World Trade Center,” according to a report by NASA’s Earth Observatory. Prior to the eruption, the caldera hosted “a large lake of lava,” NASA says.
“In July 2019, helicopter pilots began to notice water pooling into a pond in the lowest part of the crater. Water levels have risen steadily ever since,” NASA says. “Today, the lake — now with a rusty brown sheen on its surface due to chemical reactions taking place in the water — has an area larger than five football fields combined and a maximum depth of roughly ... 100 feet.”
Scientists believe the lake is growing because the crater’s floor fell low enough to put it below the water table, NASA says.

The Salpalinja, also known as the ‘Salpa Line’ is a system of more than 700 field fortifications along Finland’s eastern border. The system was built between the Winter War and the Continuation War to prevent the Soviets’s invasion of Finland. Salpalinja consisted of bunkers, trenches, fueling stations, and more. The massive wall of defense never got to fulfill its purpose, as the potential Soviet invasion never came. The system is now a popular tourist spot, as Atlas Obscura details:
Along the line are multiple museums dedicated to its past and its bunkers, as well as tours that provide a great overview of its history.
However, many bunkers, dugouts, and obstacles are buried deep in the forests, away from guided tours and foot traffic. These areas offer great experiences for those interested in a different or additional perspective from the various museums. The Ventovuori area in Virolahti offers numerous bunkers and systems to explore but it is still just a very small part of Salpalinja.
Salpalinja was painstakingly built in the name of preparedness and defense, but today it remains only as a reminder of a history that never was, but could have been.

Emma Aldenryd, 18, is known as the "human Etch A Sketch." She has dermatographia, a medical condition that makes the skin very sensitive to the touch. By using a pencil as a stylus, she can make temporary, artistic marks on her body.
Whether we’ve seen the beauty of a comet in motion through a telescope or shooting in the night skies, it’s definitely a magnificent visual worth witnessing. Its tail of gas and dust discharge that shines brilliantly as it is moved by solar winds and sunlight pressure from the sun is worth a photo for all the world to see. And the history and schedule in which it returns can prepare us to snap our own little photos for our picture collage.
For over 30 years, Paul Knapp Jr. has been taking travelers out into the Carribean Sea to let them hear the songs of the humpback whales. He has guided some 4,000 people on these listening trips. Science and tech journalist Dyllan Furness is one of these people, and he writes about his experience over at Outside Online.
After 20 minutes, we reached Knapp’s most reliable listening location, an indistinctive stretch of open water just west of a peninsula. Knapp cut the engine, plugged a hydrophone into a pair of boat speakers, and dropped the device into the water. “OK,” he said as the cable ran through his fingers, falling to 50 feet below the surface. “Let’s see if we hear anything.”
Within seconds, a chorus of cetacean song filled the air—humpbacks emanating a series of elevated chirps and bellows and downward-spiraling moans. I’d listened to countless whale recordings in preparation for the trip, but they failed to convey how haunting the songs are in person. Knapp fell silent for a few minutes before rattling off guesses at the whales’ numbers and distance from us—two or three of them, maybe three or four miles away.
Furness is lucky enough to have been able to listen to the humpback whales in person. But perhaps there will be no more humpback whale songs to listen to in the future, and that is because of human-made noise, as well as seismic blasts, which affect zooplanktons (a main food source for whales).

Ever since the release of Justice League in 2017, people have been asking for the director’s cut, which is commonly known as the Snyder Cut. On May 20 of this year, Snyder himself confirmed that it will be released.
Just recently, the official trailer of Zack Snyder’s Justice League was released, and fans are looking forward to the film, which will be shown sometime next year. The trailer features some muted scenes from the film, overlaid with the song Hallelujah.

Pfc. Austin Ferrell will most likely graduate from basic training in the US Marine Corps on September 4. He's already broken marksmanship records. Every marine is supposed to be a rifleman and Ferrell has already proven that he can deliver the lead on target with remarkable precision. The Marine Corps Times reports:
The new Marine scored 248 out of a possible 250 on Table 1 of the Marine Corps Rifle Qualification and followed it by a perfect 100 on Table 2, earning him the recruit record at Parris Island, South Carolina, under the modern scoring system.
Table 2, which consists of close range fire at multiple targets and moving targets, was added to Marine Corps rifle qualifications in 2005.
After a perfect score at 200 yards, Ferrell missed at 300, causing a loss of two points. But he once again scored perfectly at 500 yards. He was so good that some instructors were skeptical that his performance was real:
“I was told by the recruits in the pits that were doing my target that all of the drill instructors were over there talking to make sure I wasn’t cheating … because they couldn’t believe it either,” Ferrell added.
Appropriately, Ferrell hopes to become a sniper.

With so many people staying at home, gardening is bigger than ever this year. Now that harvest season is here, more people are trying their hand at home canning, so much so that manufacturers are having a hard time supplying enough mason jars. Luckily, I have plenty. If you're waiting on a shipment, you might wonder where they originally came from, and why they are named mason jars. That name comes from the inventor, John Landis Mason.
In 1858, a 26-year-old Mason patented threaded screw-top jars “such as are intended to be air and water-tight.” The earliest mason jars were made from transparent aqua glass, and are often referred to by collectors as “Crowleytown Jars,” as many believe they were first produced in the New Jersey village of Crowleytown. Unfortunately for Mason, he neglected to patent the rest of his invention—the rubber ring on the underside of the flat metal lids that is critical to the airtight seal, and made wax unnecessary—until 1868, a full decade later. By this point, mason jars were being manufactured widely. Mason tried to regain control of his invention, but after various court cases and failed business partnerships he was edged out. He died in 1902, allegedly penniless.
The jars' history continues with the Ball brothers and the rise and fall of home canning through different eras, at Smithsonian.

Alan Bellows of Damn Interesting is offering up a browser game that may drive you crazy. The object is to diffuse a bomb by flipping levers in a certain order, but there are 28 levers and if you make one wrong move, the whole building explodes. I don't know what happens if you win, because I've blown up the building every time so far.
The occasion for the game launch is to commemorate an article published exactly five years ago about an incident that occurred exactly 40 years ago. In August of 1980, a mysterious machine appeared in the back area of Harvey's Wagon Wheel Casino in Lake Tahoe, Nevada. It was a metal box with 28 toggle switches on its face. A nearby note explained that it was a bomb. The writer demanded three million dollars to be delivered in an extremely convoluted way, or the bomb would be detonated. Examination proved the device to be quite complex, and unable to be moved safely. Before long, authorities involved included the bomb squad from the local sheriff's office, plus "FBI Special Agents, the local Fire Chief, the state Fire Marshal, a military bomb disposal squad, representatives from the Nuclear Emergency Support Team, and scientists from both the Naval Surface Warfare Center and Lawrence Livermore National Laboratory." As far as the delivery of the ransom, well, the very complexity of the instructions caused that operation to go awry. The Zero-Armed Bandit is a fascinating true story that would make a good movie.
Aimee Hartley believed that she knew how to breathe. After all, that’s what she has been doing all her life. Aside from that, she was also a yoga teacher, and yoga is a practice which involves breathing exercises.
But then she took a lesson with a breathing coach, who told her where she was going wrong. He pointed out she wasn’t taking the air into her lower lungs but was, she says, an “upper chest breather. He then taught me this conscious breathing and I felt my lower belly open, and I felt myself breathing a lot better after just one session. So I then became fascinated by how we breathe.”
Now, Hartley is a Transformational Breath Coach, passing on to people what she had learned about breathwork.
These are exercises that promise to help us become better breathers, which, it is claimed by practitioners, can transform our physical and mental health by improving immune function, sleep, digestion and respiratory conditions, and reducing blood pressure and anxiety (or transporting you to a higher realm of consciousness, if that is your thing).
There is little high-quality research to back up many of these claims, although it has become widely accepted that diaphragmatic breathing (engaging the large muscle between the chest and abdomen to take bigger, deeper lungfuls of air) can reduce feelings of stress and anxiety – and the NHS recommends this for stress relief.
So how do we breathe well? See the steps over at The Guardian.

In normal times, we are amused at the phenomenon in which people have a nagging question in their everyday lives which they try to solve in the geekiest manner possible. We call that "overthinking." In 2020, people have more time to indulge in those personal missions. Ethan Rosenthal is a physicist and a data scientist in New York City, so he's had plenty of time to think about his favorite sandwich, made with peanut butter and bananas.
I start a peanut butter and banana sandwich by spreading peanut butter on two slices of bread. I then slice circular slices of the banana, starting at the end of the banana, and place each slice on one of the pieces of bread until I have a single layer of banana slices. Every time I do this, the former condensed matter physicist in me starts to twitch his eye. You see, I have this urge, this desire, this need to maximize the packing fraction of the banana slices. That is, I want to maximize the coverage of the banana slices on the bread. Just as bowl-form food is perfect because you get every ingredient in every bite, each bite of my sandwich should yield the same golden ratio of bread, peanut butter, and banana.
If you were a machine learning model (or my wife), then you would tell me to just cut long rectangular strips along the long axis of the banana, but I’m not a sociopath. If life were simple, then the banana slices would be perfect circles of equal diameter, and we could coast along looking up optimal configurations on packomania. But alas, life is not simple. We’re in the middle of a global pandemic, and banana slices are elliptical with varying size.
So, how do we make optimal peanut butter and banana sandwiches? It’s really quite simple. You take a picture of your banana and bread, pass the image through a deep learning model to locate said items, do some nonlinear curve fitting to the banana, transform to polar coordinates and “slice” the banana along the fitted curve, turn those slices into elliptical polygons, and feed the polygons and bread “box” into a 2D nesting algorithm.
Read how he did exactly that, in excruciating detail, in a study of the optimal way to make a peanut butter and banana sandwich. You could say it's bananas. -via Metafilter
