How to predict your 2023 Spotify Wrapped
How to predict your 2023 Spotify Wrapped
It's almost that time of year again, when we see how many hours we've shamelessly spent listening to mortifying music and just playing Taylor Swift on loop. Yes, Spotify Wrapped is almost here again and soon you social media feeds will be full of people either showing you how cool by how much Senegalese lounge Jazz they listen to or embarrassed that they still haven't moved on from The Libertines or The Strokes. Each and every year, even for the most dedicated of music lovers, Spotify Wrapped throws up countless surprises in your top artists and songs leading many to question just how it tallies what you listen to. With the big day somewhere on the horizon (it arrived on November 30 in 2022 and December 1 in 2021) music nerds are curious to know what their Wrapped will look like for 2023. Spotify have never officially said how they compile their data for Wrapped but a Reddit user in 2021 revealed how they believed it works. In the post Hudsonlovestech pointed out six key takeaways that they discovered after downloading their data from the music platform. They were: This year the data was logged from January 1st 00:00 to November 15th 23:59. You have to listen to a song for more than 30 seconds for it to count in your song rankings. Your top songs are calculated by play count rather than total time listened. In your top 100 playlist only the first 10 songs are sorted by play count, the rest are close but sorted by artist. Your total time listening includes podcasts. Your top artists are calculated by total play counts rather than total time listening. If you apply this date to your own listening history then there is a chance you might discover what your Wrapped will look like this year although there is no guarantee. Meanwhile, many users on X/Twitter are posting memes, imagining what their Wrapped will look like this year. To be honest, we're just dreading seeing how much we listened to Ryan Gosling sing 'I'm Just Ken' from the Barbie soundtrack.

How a Scottish boy digging for potatoes found an ancient Egyptian 'masterpiece'
How a Scottish boy digging for potatoes found an ancient Egyptian 'masterpiece'
For decades, archaeologists have been trying to work out how a trove of ancient Egyptian artefacts were buried in the grounds of a school in Scotland. In 1952, a schoolboy was sent to dig up potatoes as a punishment – how times have changed – when he found a statue. It turned out to be a masterpiece made some 4,000 years ago. Fourteen years later, more treasure was discovered by a boy during a PE class, before, in 1984, a group found another item with a metal detector. It turned out to be part of a set of 18 antiquities dug up over the next 30 years at Melville House, a historic building in Fife, Scotland. But nobody had any idea how they got there. Now, researchers think they might have unearthed what was going on. Alexander Lesie-Melville was a young heir to Melville House when he travelled to Egypt in 1856. A year later, he had returned to Scotland and died. Leslie-Melville might have picked up the collection on his travels – it certainly beats the Duty Free section at Heathrow – as antique dealers routinely sold ancient artefacts to rich foreigners during that period. After Leslie-Melville died, family members are thought to have moved the objects to an outbuilding, where they were promptly forgotten about. The outbuilding was then demolished. Margaret Maitland, principal curator of the Ancient Mediterranean at National Museums Scotland where most of the objects are housed, said: “The discovery of ancient Egyptian artifacts that had been buried in Scotland for over a hundred years is evidence of the scale of 19th century antiquities collecting and its complex history.” “It was an exciting challenge to research and identify such a diverse range of artefacts.” Dr Elizabeth Goring, who has since investigated the site, said: “Excavating and researching these finds at Melville House has been the most unusual project in my archaeological career, and I’m delighted to now be telling the story in full." The full story will be published in an upcoming article in the journal Proceedings of the Society of Antiquaries of Scotland.

A terrifying thing happens to astronauts' fingernails on a spacewalk
A terrifying thing happens to astronauts' fingernails on a spacewalk
Going on a spacewalk might sound like a lot of fun – but in reality it’s no walk in the park. From their muscles getting less dense all the way to erectile dysfunction, astronauts have to put up with all sorts of things going wrong with their body. And none more gross than what happens to their fingernails. Turns out they just fall right off. The technical term for this is onycholysis, and it has to do with how much – or how little – atmospheric pressure there is in space. Because there is so little ambient pressure in space, astronaut’s space suits need to be pressurised to keep the human body intact. But that’s not good for the hands, it turns out. “Injuries to the hands are common among astronauts who train for extravehicular activity (EVA),” says a 2015 conference paper by space specialists Wyle Laboratories. “When the gloves are pressurized, they restrict movement and create pressure points during tasks, sometimes resulting in pain, muscle fatigue, abrasions, and occasionally more severe injuries such as onycholysis. “Glove injuries, both anecdotal and recorded, have been reported during EVA training and flight persistently through NASA's history regardless of mission or glove model." A 2010 study looked at 232 hand injuries sustained by astronauts, and found that the wider your knuckle joints, the more likely you are to suffer in a space suit. The study suggested that because space suit gloves limit the mobility of these knuckles, the fingers then get put under more pressure. This, in turn, means less blood gets to the fingers, and risks onycholysis. Ouch. Work has been done to try to improve the design of space suit gloves, of course. One team found that the more tailored they were to each astronaut’s finger length the less likely they were to lose their fingernails. That’s no mean feat, however. These gloves are made of at least four layers: one which touches the skin, one which helps create the pressurised environment, another one which makes the pressure layer less stiff, and an outer layer which protects the astronaut from everything on the outside. Mercifully for NASA astronauts at least, they usually have their gloves fitted to each wearer, and with new space suit design moving forward each day, the number of injuries is decreasing. Nonetheless, it sounds like a trip to space is no time for a manicure.

New research suggests dinosaurs were wiped out by more than just a meteorite
New research suggests dinosaurs were wiped out by more than just a meteorite
We’ve all been told the story of what wiped out the dinosaurs – a giant meteor careers down from the sky, crashes into Earth and bang! The rest is history. But what if that wasn’t the whole story? A new study suggests there may have been more to it than just an asteroid – and it involves climate change. A chain of huge volcanic eruptions which eventually cooled the planet an alarming amount may have been partially to blame, according to research. The study, published in Science Advances and co-authored by Don Baker, a professor in McGill University's Department of Earth and Planetary Sciences, suggests that this might be the case. The researchers looked into volcanic eruptions at the Deccan Traps, a huge, rugged plateau that formed when molten lava solidified and turned to rock. The plateau dates back to around 66-65m years ago, when magma from deep inside Earth erupted to the surface. That just so happens to be around the time when scientists think the dinosaurs met their demise. Baker’s team suggest that the eruptions produced a staggering 1m cubic kilometres of lava, which then turned into rock, which may have played a key role in cooling the global climate around 65m years ago. The scientists say it’s all to do with how much sulphur and fluorine was pumped into the atmosphere as a result of the eruptions. Incredibly, they found the event could have sparked a drop in temperature all around the world, dubbed a “volcanic winter”. Baker said: “Our research demonstrates that climatic conditions were almost certainly unstable, with repeated volcanic winters that could have lasted decades, prior to the extinction of the dinosaurs. “This instability would have made life difficult for all plants and animals and set the stage for the dinosaur extinction event. “Thus our work helps explain this significant extinction event that led to the rise of mammals and the evolution of our species.” The scientists worked it out using new chemical techniques developed at McGill to measure how much sulphur is in the rock formations which came about at the time, then from that, figuring out how much went into the atmosphere. The paper is titled “Recurring volcanic winters during the latest Cretaceous: Sulfur and fluorine budgets of Deccan Traps lavas.” How to join the indy100's free WhatsApp channel Sign up to our free indy100 weekly newsletter Have your say in our news democracy.

Metal detectorist finds mystery rock that turns out to be worth more than gold
Metal detectorist finds mystery rock that turns out to be worth more than gold
Metal detecting can be a pretty thankless task, with most enthusiasts lucky if they find a couple of quid or an old belt buckle. But for one man in Australia, the experience was out of this world. David Hole was out digging for gold in Maryborough Regional Park, near Melbourne, back in 2015 when his trusty detector alerted him to a strange, red-brown rock embedded in some yellow clay. Hole took the mysterious boulder home with him and did his utmost to crack it open, using a rock saw, a sledgehammer, a drill, and even dousing it in acid, according to Science Alert. And yet, nothing left so much as a dent. Admitting defeat years later, in 2018, Hole took his find to the Melbourne Museum, hoping someone there could explain its impenetrability; convinced it contained a golden nugget. However, the discovery was far more significant than a precious metal: it was a 4.6 billion-year-old glimpse at the birth of our solar system – a rare meteorite that had crashed down to Earth. The museum’s geologists, Dermot Henry and Bill Birch, said they grew excited as soon as Hole pulled the enigmatic rock from his rucksack. Speaking to the Sydney Morning Herald back in 2019, Henry recalled: "It had this sculpted, dimpled look to it. "That's formed when they come through the atmosphere, they are melting on the outside, and the atmosphere sculpts them." Meanwhile, Birch told the paper he knew the specimen was special as soon as he held it. “If you saw a rock on earth like this, and you picked it up, it shouldn’t be that heavy,” he said. Testing soon confirmed their suspicions, as well as the composition of this extraordinary chunk of history. In July 2019, the two colleagues published a scientific paper describing the meteorite, which they christened “Maryborough”, after the area where it was found. The space rock, which measures 38.5cm by 14.5cm by 14.5cm, weighs a staggering 17 kg, and after using a diamond saw to slice through it, the experts discovered that it is what is known as an H5 ordinary chondrite. This means that it contains tiny crystallised droplets (chondrules), that were created by flash heating of dust clouds in the early solar system. "Meteorites provide the cheapest form of space exploration. They transport us back in time, providing clues to the age, formation, and chemistry of our Solar System (including Earth)," Henry said in a statement published by Museums Victoria. "Some provide a glimpse at the deep interior of our planet. In some meteorites, there is 'stardust' even older than our Solar System, which shows us how stars form and evolve to create elements of the periodic table. "Other rare meteorites contain organic molecules such as amino acids; the building blocks of life." The scientist added that the Maryborough Meteorite was most likely formed in the asteroid belt between Mars and Jupiter. Despite all of Henry and Birch’s work, plenty of questions surrounding the rock remain unanswered. They don’t know for sure when it landed on Earth, with carbon 14 testing it was between 100 and 1,000 years ago. Still, multiple meteor sightings were reported in the Maryborough district between 1889 and 1951, so it could have crashed down within this relatively recent time period. Whatever its precise origins, the researchers insist it’s worth more to science than its weight in gold. "This is only the 17th meteorite found in Victoria, whereas there's (sic) been thousands of gold nuggets found," Henry told Channel 10 News at the time. "Looking at the chain of events, it's quite, you might say, astronomical it being discovered at all." Birch echoed this sentiment, adding: “When you consider all the events this chunk of rock has experienced since its formation 4.6 billion years ago, it's really mind-boggling that we get the opportunity to hold it and study it today.

Women may have been better hunters than men, scientists find
Women may have been better hunters than men, scientists find
Scientists are challenging the way many people think about ancient hunter gatherers, after finding that women may have been better hunters than men. New findings have shown that while there are clear differences between the sexes when it comes to biology, the idea of men being naturally better suited to hunting is a myth. New research from professor Cara Ocobock points to women being metabolically better placed to hunt. Ocobock is an assistant professor in the Department of Anthropology and director of the Human Energetics Laboratory at the University of Notre Dame. She published a study on the subject alongside anthropologist Sarah Lacy at the University of Delaware. The research also points to female hunters dating back to the Holocene period which were uncovered buried with hunting tools – and they’re challenging widely held assumptions over gender roles with the study. Ocobock said in a statement: "This was what everyone was used to seeing. This was the assumption that we've all just had in our minds and that was carried through in our museums of natural history." “Here we review and present emerging physiological evidence that females may be metabolically better suited for endurance activities such as running, which could have profound implications for understanding subsistence capabilities and patterns in the past,” the pair wrote. That’s due to the fact that the presence of the hormones estrogen and adiponectin give women the upper hand when it comes to endurance – a factor which would have been “critical in early hunting because they would have had to run the animals down into exhaustion before actually going in for the kill”. The presence of those hormones is better for modulating fat and glucose. As such, estrogen makes the body use stored fats for energy before turning to carbohydrates. “Since fat contains more calories than carbs do, it’s a longer, slower burn, which means that the same sustained energy can keep you going longer and can delay fatigue,” Ocobock said. “Estrogen is really the unsung hero of life, in my mind. It is so important for cardiovascular and metabolic health, brain development and injury recovery.” “With the typically wider hip structure of the female, they are able to rotate their hips, lengthening their steps. The longer steps you can take, the ‘cheaper’ they are metabolically, and the farther you can get, faster.” “When you look at human physiology this way, you can think of women as the marathon runners versus men as the powerlifters.” Sign up for our free Indy100 weekly newsletter How to join the indy100's free WhatsApp channel Have your say in our news democracy.
