Expert uses science to explain what causes so many Bermuda Triangle disappearances
Expert uses science to explain what causes so many Bermuda Triangle disappearances
One expert believes he’s “solved” the mystery of the Bermuda Triangle. Channel 5’s documentary, Secrets of the Bermuda Triangle, featured an interview with mineral prospector Nick Hutchings. Hutchings said that geology could explain the disappearances of planes and boats. According to the National Oceanic and Atmospheric Administration (NOAA), the Bermuda Triangle is in the western part of the North Atlantic Ocean and “has captured the human imagination with unexplained disappearances of ships, planes, and people.” The region has also been referred to as ‘The Devil’s Triangle’, with reports of disappearances in the area date as far back as the middle of the 19th century. Reports of distress signals or wreckages resulted in crews and passengers never being heard from again. Many have come up with conspiracy theories in an attempt to explain the bizarre occurrences that happen in and around the Bermuda Triangle. Some believe the lost city of Atlantis is responsible, others think it has something to do with rogue waves, and few go as far to suggest it is a portal to another space and time. But Hutchings has a different theory. This one involves rocks. “Bermuda’s basically a sea mountain - it’s an underwater volcano. 30 million years ago, it was sticking up above sea level,” Hutchings explained. “It has now eroded away and we’re left with the top of a volcano. We have a few core samples, which have magnetite in them. It’s the most magnetic naturally occurring material on Earth.” Using only a small piece of rock and a compass, Hutchings conducted an experiment during the documentary to demonstrate what this meant for ships sailing through the area. When the compass was passed over the rock its needle went berserk, ultimately resulting in the navigational device being completely useless. “You can just imagine the ancient mariners sailing past Bermuda,” he explained. “It would be very disconcerting.” In other words - people travelling through simply got lost. Whilst the Bermuda Triangle may seem to be this mysterious location, scientist at Sydney University, Karl Kruszelnicki, claims the percentage of missing planes and boats is similar to any other high-traffic part of the ocean.

Material discovered on Mars would be ’signs of life’ if found on Earth
Material discovered on Mars would be ’signs of life’ if found on Earth
A Nasa scientist has said chemicals found on Mars would be considered signs of ancient life if they were found on Earth, leading to suggestions the Red Planet could potentially have harboured life. Dr Michelle Thaller said: “On Mars we see chemistry that on Earth, if it were here, we would say is due to life. “But the question is, how well do we understand Mars and are we being fooled by something?” It’s not a done deal, of course. Signs of ancient life that we find regularly on Earth may not mean the same thing elsewhere, particularly with the vastly different conditions between the two planets. Dr Thaller told The Sun she is certain there is life out there in our solar system, but did not reveal the exact chemical substance that had been found. Nasa has previously found methane on Mars, which it said “could have supported ancient life”, and the organisation has also revealed plans to look for amino acids that haven’t yet been destroyed by space radiation. Organic chemicals like amino acids are used by archaeologists to determine whether life was present. A blog post from the US space agency said: “Amino acids can be created by life and by non-biological chemistry. “However, finding certain amino acids on Mars would be considered a potential sign of ancient Martian life because they are widely used by terrestrial life as a component to build proteins. “Proteins are essential to life as they are used to make enzymes which speed up or regulate chemical reactions and to make structures.” Alexander Pavlov of Nasa’s Goddard Space Flight Center in Greenbelt, Maryland, added: “Our results suggest that amino acids are destroyed by cosmic rays in the Martian surface rocks and regolith at much faster rates than previously thought. “Current Mars rover missions drill down to about two inches (around five centimeters). “At those depths, it would take only 20 million years to destroy amino acids completely.” That may sound like a long time, but Nasa is looking for life that is billions of years old, because scientists think Mars would have been more like Earth back then. Dr Thaller said it was important not to actually say there were signs of life until there is 100 per cent confirmation. “The solar system may be teeming with simple life, microbial life. “We just have to get that 100% certainty to say that we found it and we don’t have that yet.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

AI in music: The top artists are are for and against the technology
AI in music: The top artists are are for and against the technology
With the rise of AI, we've all seen how powerful this new technology can be particularly when it comes to music. As a result, people have been using AI to perfectly replicate the singing voices of different artists such as Drake, Ariana Grande, Billie Eilish, Taylor Swift and Harry Styles in order to make AI covers of different songs. For example, there is a viral AI cover of Harry Styles singing in a duet with Taylor Swift on her track Style which fans have been going crazy about. While AI can also be used to create deep fakes of celebrities too - where the celeb's face is digitally imposed on someone else's body which is often used to spread misinformation or for malicious intent. But what do artists think about this issue? Here are the celebrities who have spoken out so far on the topic of AI: Drake An AI song called "Heart on My Sleeve" that used Drake's and the Weeknd's voices went viral before being taken down by music streaming services. While Drake himself hasn't commented on all the AI songs that have been created, he did express his disapproval of the practice after the rapper responded to an AI-generated cover of him rapping Ice Spice’s “Munch”, writing: “This is the final straw AI.” Grimes Grimes has expressed enthusiasm towards the new AI-generated songs - and has told her fans they can use her voice to create their own tracks. Taking to Twitter, she shared a New York Times article about the viral AI-generated song using Drake and The Weeknd's voice. She wrote: "I'll split 50 per cent royalties on any successful AI-generated song that uses my voice. Same deal as I would with any artist I collab with. Feel free to use my voice without penalty. I have no label and no legal bindings." "I think it's cool to be fused w a machine and I like the idea of open-sourcing all art and killing copyright," she added. Though, later she did add a clarification on the platform as to what circumstances would cause her to get certain AI songs taken down for copyright - where "rly rly toxic lyrics," are used with her voice. "Ok hate this part but we may do copyright takedowns ONLY for rly rly toxic lyrics w grimes voice: imo you'd rly have to push it for me to wanna take smthn down but I guess plz don't be *the worst*. as in, try not to exit the current Overton window of lyrical content w regards to sex/violence. Like no baby murder songs plz," she wrote. "I think I'm Streisand effecting this now but I don't wanna have to issue a takedown and be a hypocrite later. ***That's the only rule." Rly don't like to do a rule but don't wanna be responsible for a Nazi anthem unless it's somehow in jest a la producers I guess "- wud prefer avoiding political stuff but if it's a small meme with ur friends we prob won't penalize that. Probably just if smthn is viral and anti abortion or smthn like that. Grimes added: "Rly rly don't like adding rules so I apologize but this is the only thing." Most recently, the singer and producer has shared a guide on how to do this, and shared the link in a tweet: "HOW TO MAKE MUSIC FEAT GrimesAI - we can distribute it for you and you can earn royalties from your work." Billie Eilish During an appearance on The Late, Late Show with James Corden back in May this year, Billie Eilish shared her thoughts on AI. "I feel like my approach is not as optimistic, I'm a little bit scared of it," she admitted. "I'm a little scared of what someone could create of me doing something with it." Eilish added: "Scary, scary to me, it just looks so real," as she went on to note how it's "One of the most impressive things I've encountered in my life." The singer's comments come after deepfake porn' of singer Eilish was promoted on people's TikTok in December last year.

Mystery of how a meteor left Earth thousands of years ago, then came back
Mystery of how a meteor left Earth thousands of years ago, then came back
Baffled scientists are trying to unravel the mystery of how a meteorite left Earth’s atmosphere and somehow came back again. Unlike boomerangs, meteorites don’t have a reputation for coming back around again, so when a black rock found in Morocco in 2018 seemed to have done just that, it left the scientific community confused. The rock, whose official name is Northwest Africa (NWA) 13188, is a scientific first (that we know of) to have left the Earth’s atmosphere, gone into outer space and returned again. The 646-gram piece of rock is remarkable not only for its journey but also its makeup. NWA 13188 has a bubbly texture and contains crystals. Its chemical components suggest that the rock is made out of the minerals produced by molten minerals that come from volcanic activity. It also possesses trace elements and oxygen isotopes, which suggests to scientists that it is not the typical meteorite that originates in space, but instead, it originated on Earth itself. However, according to a geophysicist from the French National Centre for Scientific Research, Jérôme Gattacceca, who studied the rock and presented the findings, it has undergone an interesting journey in orbit. Scientists can identify this because of the presence and concentration levels of Helium-3, Beryllium-10, and Neon-21, which suggest exposure to cosmic rays that are not present in Earth’s atmosphere. Compared to other more traditional meteorites scientists have studied, the concentrations are lower on NWA 13188 but are still higher than rocks on Earth. It is thought that NWA 13188 could have been expelled from Earth and in orbit for thousands of years. Scientists said, “We consider NWA 13188 to be a meteorite, launched from the Earth and later re-accreted to its surface”. Despite the rock originating on Earth, the team said it fits the definition of a meteorite since it has achieved orbit. The definition states: “Material launched from a celestial body that achieves an independent orbit around the Sun or some other celestial body, and which eventually is re-accreted by the original body, should be considered a meteorite. “The difficulty, of course, would be in proving that this had happened, but a terrestrial rock that had been exposed to cosmic rays and had a well-developed fusion crust should be considered a possible terrestrial meteorite.” It is not yet understood how the rock came to be launched from Earth into space, as researchers said it still “remains to be determined”.

150 million year old water trapped in salt contains secrets to our ocean history
150 million year old water trapped in salt contains secrets to our ocean history
The key to discovering the secrets of life at the bottom of the ocean 150 million years ago has been discovered, and it was trapped inside ancient salt formations this whole time. Experts have been able to uncover the Earth's geological history y studying tiny water particles which have been preserved in crystals for millions of years. It’s all to do with analysing the amount of lithium which is trapped in samples rock salt. As it turns out, the level of lithium can tell us far more about atmospheric conditions in the oceans over the ages than most of us previously realised. Geochemists Mebrahtu Weldeghebriel of Princeton University and Binghamton University and Tim Lowenstein of Binghamton University have published their findings in a new study. The rock salt they studied, known as marine halite, came from across the world including the US, Europe, Asia and Africa. A total of 639 samples were taken from 65 halite crystals dating back to 150 million years ago. "There is a close link between ocean chemistry and atmospheric chemistry," Weldeghebriel said. “Whatever changes happen in the ocean also reflect what's happening in the atmosphere." "The oceans and atmosphere are connected to one another, and how they change is related," Lowenstein added. "Everything is connected." Most notably, their findings have helped to create a better understanding of tectonic movement on the seafloor. The reason the presence of lithium was so important is due to what it tells us about hydrothermal activity. The amount in the water indicates the levels of chemicals and heat which was being released into the oceans by vents between tectonic plates. As tectonic plate activity declined, there was a global drop in lithium levels. Instead, it was replaced by a rise in magnesium and calcium. The reduction in activity would also have meant less carbon dioxide being released into the atmosphere, which could potentially have been a factor in the temperature drop which resulted in the ice age.

'Hidden structures' discovered deep beneath the dark side of the moon
'Hidden structures' discovered deep beneath the dark side of the moon
Scientists have just uncovered billions of years’ worth of secrets buried beneath the surface of the moon. Our celestial companion has been a source of awe and mystery since time immemorial, but now, thanks to China’s space programme, we’re starting to piece together its past. In 2018, the Chang’e-4 lander, of the Chinese National Space Administration (CNSA), became the first spacecraft ever to land on the far side (or the dark side, if you'd prefer) of the moon. Since then, it has been capturing incredible images of impact craters and extracting mineral samples, offering a long-sought insight into the structures that make up the top 1,000 feet of the moon’s surface. Earlier this month, the Chang’e-4’s findings were finally published, and the world was invited to delve deep into the history of our cherished natural satellite. The results, published in the Journal of Geophysical Research: Planets, reveal that the top 130 feet (40m) of the lunar surface are made up of multiple layers of dust, soil, and broken rocks. Hidden within these layers is a crater, which formed when a large object slammed into the moon, according to Jianqing Feng, an astrogeological researcher at the Planetary Science Institute in Tucson, Arizona, who co-led the pioneering analysis. Beneath this, Feng and his colleagues discovered five distinct layers of lunar lava that spread across the landscape billions of years ago. Experts believe that our moon formed 4.51 billion years ago, when a Mars-size object crashed into Earth and broke off a chunk of our planet, as Live Science notes. Over the following 200 million years or so, the moon continued to be pummelled by space debris, with numerous impacts leaving cracks in its surface. Just like on Earth, the moon’s mantle contained pockets of molten magma, which infiltrated the newly formed cracks thanks to a series of volcanic eruptions, Feng explained. However, the new data provided by Chang’e-4 showed that the closer the volcanic rock was to the moon’s surface, the thinner it got. "[The moon] was slowly cooling down and running out of steam in its later volcanic stage," Feng said. "Its energy became weak over time." It is understood that volcanic activity on the moon died out between a billion and 100 million years ago, which means it is largely considered “geologically dead”. However, Feng and his co-authors have suggested there could still be magma buried deep beneath the lunar surface. Chang’e-4 still has much work to do, and Feng and his team hope this is just the beginning of their literally ground-breaking mapping of the moon.
