A landmark discovery on an ancient branch of the River Nile may have solved the mystery of how the pyramids in Egypt were built centuries ago. The now dried-out waterway, which once ran through Giza might have been used to transport the materials that were used to construct the pyramids. The proximity to the waterway might also suggest why there is such a cluster of pyramids in that particular area of Cairo, as the large amount of water would have been able to support the various building blocks needed for the colossal structures. The discovery was made by Dr Eman Ghoneim who used radar satellite data from space to study the Nile Valley which showed an "invisible world of information beneath the surface." Ghoneim presented her research to the 13th Congress of Egyptologists earlier this year. Speaking to IFLScience Ghoneim said: "The length probably was really, really long, but also the width of this branch in some areas was huge. We're talking about half a kilometer or more in terms of width, which is something that is equivalent to today's Nile course width. So it wasn't a small branch. It was a major branch.” The defunct waterway has been dubbed the Ahramat Branch and ran from Giza to Faiyum and amazingly passed through 38 different pyramid sites. However, without confirmation of whether the river was active during the Old and Middle Kingdoms, around 4,700 years ago, cannot fully determine if water was used to help build the pyramids. One indication that it could have been used is that according to Ghoneim these pyramids were "located exactly at the bank of the branch that we found" which could mean that they were "valley temples" which acted like ancient ports. The research might not just unlock the secrets of the pyramids but it could also uncover parts of ancient Egypt that have long been lost as towns disappeared when the Nile naturally migrated. Ghoneim added: "As branches disappeared, Ancient Egyptian cities and towns also silted up and disappeared, and we have no clue actually where to find them."

A solar storm predicted to hit Earth on Friday (December 1) may cause internet blackouts, according to forecasters. Radio and GPS could also be affected due to the solar storm, also known as a coronal mass ejection (CME), which is caused by interference with Earth’s magnetic field. "A Direct Hit! The impressive #solarstorm launched in the Earth-strike zone has been modeledmodelled by NASA," space weather physicist Dr Skov posted on Twitter/X. "The storm is predicted to hit Earth by midday December 1. Along with two earlier storms already en route means we have a 1,2,3-punch. If the magnetic field is oriented correctly, expect #aurora to reach deep into mid-latitudes." She added: "Amateur #radio & #GPS reception issues are likely, especially on Earth's nightside. G3+ conditions are possible with this storm series." A solar storm can have substantial effects on the Earth, taking place when the sun emits powerful bursts of energy which come from solar flares and CME that contain charged plasma. During which, a stream of an electromagnetic field is directed towards Earth and this causes the aurora borealis. Three solar storms were predicted to advance towards Earth – and some may merge, resulting in increased disruptions to Earth’s magnetic field, according to The US National Oceanic and Atmospheric Administration (NOAA). “Along with two earlier storms already en route [this] means we have a 1,2,3-punch,” Dr Skov said. Consequently, she added there are “excellent chances” of strong G3-level magnetic storms and auroras on Earth. The way the strength of a solar storm is measured is with the letter G and then a number system from 1-5 (1 being the weakest, to 5 being the strongest). So a G3 level storm means radio, internet and GPS could be affected due to the strength of these events. Solar storms are also known to cause electrical grids and knock out satellites, depending on their strength. Meanwhile, experts have warned the solar storm thought to occur today may impact communication systems in high latitudes. “With 3 CMEs already inbound, the addition of a 4th, full halo CME has prompted SWPC forecasters to upgrade the G2 Watch on 01 Dec to a G3 Watch. This faster-moving halo CME is progged to merge with 2 of the 3 upstream CMEs, all arriving at Earth on 01 Dec,” the NOAA said. “G3 (strong) conditions are now likely on 01 Dec,” it added.

Fire might seem like one of the most elemental things in the natural world, but it’s never been found anywhere other than Earth. It’s because the creation of fire relies on very specific circumstances. In fact, if fire was ever found on another planet, it would be a good indicator of the possible existence of life. Oxygen is key to fire, and while it’s particularly prevalent in the universe, Earth’s atmosphere features an abundance of the element in the right molecular form for it to form. Even then, the way the Earth’s atmosphere has changed over its lifespan is also crucial to conditions being fostered where fire can form [via IFLScience]. For millions of years, in fact, there wasn’t enough oxygen in the atmosphere to create fire. Before the Middle Ordovician period, when there was far less oxygen, there’s no evidence of fire whatsoever. Most of the fuel that fire needs is also directly related to life existing on the planet – think wood, oil and coal. Without life, there isn’t an awful lot of fuel going around, which just shows why the existence of fire on another planet would be a very promising sign when it comes to exploring the universe for life. Despite fire being much rarer in the universe than most might think, it was previously confirmed that humans in Europe may have mastered fire long before we previously thought. According to a study published in Scientific Reports, humans made the discovery around 245,000 years ago, up to 50,000 years earlier than scientists believed, Researchers studied samples from the Valdocarros II, a huge archaeological site found east of Madrid, Spain. Using chemical analysis, they found certain compounds that show things were burnt by fire in "organised" social events, rather than through accidents or wildfires.

A study last year found that every time you throw away a banana peel, you're missing out on a great snack. The study, published in ACS Food Science & Technology, found that if banana peels are blanched, dried, and ground into a flour, they can be turned into baked goods that taste just as good as wheat-based products. And it turns out it's actually really food for you. Consuming products made from banana peel means you consume minerals and cancer-fighting minerals. Sugar cookies that were enriched with banana peels not only tasted the same as peel-free sugar cookies, but contained much more fibre, magnesium, potassium, and antioxidant compounds. In 2021, a study on banana peel cake found the yellow skin of the fruit provided a natural food colour as well as a nutritional boost. Whilst a 2016 study found that substituting up to 10 per cent of wheat flower with banana peel flour can enrich baked bread with higher protein, carbohydrate, and fat contents. Not only is it a healthy food option, it also helps reduce food waste! And the same goes for other fruits too, such a mango skin, what was found to boost a cake's antioxidant properties and improve its flavour. Just make sure to add the right amount of banana peel to your bakes and makes. Adding too much banana peel flour did result in the study's cookies going somewhat brown and hard, possibly from all the extra fibre. 7.5 percent of banana peel flour seems to be the sweet spot, with the texture and taste hitting an appealing balance. So maybe reconsider next time you go to thrown a banana skin away. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Our canine companions could soon be enjoying much longer lifespans, if a drug which claims it can extend dogs’ lives eventually gets approved. The drug, made by a tech firm in California, just cleared a vital hurdle to doing just that, after it got partial approval by regulators in the US. Loyal, a San Francisco-based company founded in 2020, has been researching how it can increase dogs’ lifespans – in particular larger breeds, which tend to die younger. Large and “giant” breeds tend to live to between eight and 12 years. Smaller dogs, such as Chihuahuas, can keep going to the ripe old age of 20. Loyal’s main product, the catchily-titled LOY-001, is designed not only to extend dogs’ lives but also maintain their quality of life. Now, it has passed the “reasonable expectation of effectiveness” test, set by regulators at the US’ Food and Drug Administration. Loyal’s chief executive, Celine Halioua, said: "Loyal was founded with the ambitious goal of developing the first drugs to extend healthy lifespan in dogs. "This milestone is the result of years of careful work by the team. We'll continue to work just as diligently to bring this and our other longevity programs through to FDA approval." Selective breeding of dogs has caused higher levels of hormones which help the animals grow faster. That is also believed to reduce their lifespan, the company said. Big dogs tend to have more of this hormone than their smaller counterparts. Animal rights activists are not yet convinced. Some experts fear it will only serve to extend animals’ suffering. Loyal, on the other hand, says the drug aims to treat doggy diseases which are associated with ageing through preventing them, rather than waiting for the animals to get sick before treating them. The company said that the drug could be available to US customers as early as 2026. So that’s plenty of time for walkies between now and then.

When archaeologists explored an underwater cavern in southern Mexico in 2014, they were shocked by what they found. The cavern is known as Sac Uayum, and is located in Mexico’s Yucatán peninsula. It is technically a cenote – a natural pit that comes about after limestone bedrock collapses, exposing groundwater beneath. Local villagers were said to be terrified of the spot, because pits like this were sometimes used by the ancient Maya for sacrificial offerings. Archaeologist Bradley Russell, from College of St Rose, and a group of divers scaled down roughly 20 metres into the unknown. Inside the pit were two chambers with human bones and skulls scattered across the floors of each. The skulls were elongated, as part of an ancient practice that is thought to have involved flattening people’s heads during infancy. Archaeologists still don’t know why the ancient culture did this – but it ain't pretty. The cenote sits just outside the ruins of the ancient Maya city of Mayapán, and the researchers think this shows that, like the modern day locals, the ancient Mayans kept their distance too. Local legend says that Sac Uayum is guarded by a feathered, horse-headed serpent. Older residents of the nearby village of Telchaquillo tell stories of people seeing the serpent perching in a tree, leaping up, spinning around three times, and diving into the water. Russell explained to National Geographic that the sinkhole is said to be “evil”. “To this day, people do not get drinking water from that cenote, it is generally considered taboo. “It’s off-limits, people do not let their children plan near there and there’s a lot of beliefs around this cenote having evil forces or malevolent forces associated with it. “Cenotes are important because the main access to the water that you get is through these sinkholes. “They are also believed to be access to the Mayan underworld and the homes of Gods. “Mayapan is a large city, it’s incredibly dense, there’s nothing like it in the classic period, it’s incredibly dense for Maya history, there’s nothing quite like it.” He added that the location of Sac Uayum – south of Mayapan – is a clue as to what was going on. In Maya beliefs, south is the direction associated with the underworld. Alternatively, Russell also suggested they could have been plague victims. "You wouldn't want them near the rest of the population. And you wouldn't want to drink the water either.” How to join the indy100's free WhatsApp channel Sign up to our free indy100 weekly newsletter Have your say in our news democracy.

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 here again and soon your 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. The past few years Wrapped has arrived earlier and earlier, as reported by the Radio Times, so it's not surprise that its arrived on November 29th. Here are the dates it arrived on the previous years. 2017: 6th December 2018: 6th December 2019: 5th December 2020: 2nd December 2021: 1st December 2022: 30th November Finding your Wrapped couldn't be easier you just need to go to your Spotify app on the day it drops and it'll be there waiting for you at the top of the app alongside your saved songs and albums. Alternatively, if you just use Spotify on a laptop or desktop you can visit spotify.com/wrapped and use it from there. 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.

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.

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.

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.
