Scientists have found an explanation for a 'gravity hole' in the Indian Ocean. A gravity hole is an area where gravitational pull is low, causing the seafloor to sink. Deep beneath the ocean, there is one that is three million square kilometers in size and previously it has confused scientists. Now two researchers from the Indian Institute of Science, Debanjan Pal and Attreyee Ghosh, think they have solved the mystery. More than 1,000 kilometers (621 miles) beneath Earth's crust, they found cold, dense remnants of an ancient ocean plunged into a 'slab graveyard' beneath Africa some 30 million years ago, stirring up hot molten rock. Sign up to our free Indy100 weekly newsletter Pal and Ghosh retraced the formation of the massive geoid by modeling how tectonic plates skimmed over Earth's mantle for the past 140 million years. They ran simulations and compared the shape of the oceanic low those models predicted with observations of the dent itself. The models that reproduced the Indian Ocean geoid low in its current form all had one thing in common: plumes of hot, low-density magma wafting up beneath the low. These plumes, as well as a distinctive mantle structure, are what created the geoid low; if they rise high enough, Pal and Ghosh reckon. "In short, our results suggest that to match the [shape and amplitude of the] observed geoid low, plumes need to be buoyant enough to come up to mid-mantle depths," the pair wrote. The first of these plumes appeared about 20 million years ago, to the south of the Indian Ocean geoid low, and around 10 million years after the old Tethys Sea sank into the lower mantle. As the plumes spread beneath the lithosphere and inched towards the Indian peninsula, the low intensified. But more research needs to be done to work out what is really going on as not all scientists are convinced. Science is crazy. Have your say in our news democracy.

For years people have been looking to the skies for signs of alien life - but maybe, they should have been looking at the bottom of the ocean this whole time. A Harvard physicist has claimed that parts of an alien 'spacecraft' could have been uncovered under the sea. Professor Avi Loeb set off on a search along the bottom of the Pacific Ocean and found 50 iron pieces which originated from the IM1 meteor. IM1 crashed off the coast of Papua New Guinea and Leob believes it could contain key information in the search for life out there in the universe, saying he hasn’t discounted the idea of the pieces being evidence of a “spacecraft” from an “extraterrestrial technological civilization” which crashlanded on Earth. Sign up to our free Indy100 weekly newsletter Loeb is currently the head of Harvard’s Galileo Project, focusing on the search for aliens, and he said the fragments they found must have come from “a natural environment different from the solar system, or an extraterrestrial technological civilization.” Speaking to Fox News Digital, Loeb detailed his thoughts on the origins of the meteor fragments by saying: “Given IM1's high speed and anomalous material strength, its source must have been a natural environment different from the solar system, or an extraterrestrial technological civilization.” He added that IM1 “is actually tougher and has material strength that is higher than all the space rocks that were catalogued by NASA. That makes it quite unusual.” Have your say in our news democracy. Click the upvote icon at the top of the page to help raise this article through the indy100 rankings.

It’s footage that’s fascinated conspiracy theorists for decades, but artificial intelligence is making people look at the most famous alleged sighting of ‘Bigfoot’ in a new light. Back in 1967, a clip known as the Patterson–Gimlin film claimed to show the mysterious creature, also known as ‘sasquatch’, walking through the Six Rivers National Forest in California. Roger Patterson and Robert Gimlin shot a figure moving in the woods in low resolution footage and claimed that they had discovered proof of the urban legend known as Bigfoot. The pair claimed at the time they tracked the figure before setting up filming equipment and capturing grainy video which looks briefly at the camera. Sign up to our new free Indy100 weekly newsletter While it was dismissed by the scientific community at the time and seen as a hoax by most people, it’s been poured over by conspiracy theorists ever since. It’s been analysed many times since, but new artificial intelligence has been used to present a clearer image than ever before. The clip has been stabilised and de-grained, and the results are clearer than ever. Social media user Rowan Cheung often shares the “latest developments in the world of artificial intelligence” and he posted the footage. Just as many conspiracists will have feared, the newly treated footage proves that it was clearly just a guy in a gorilla costume all along. Yes, we all knew that already, but this newly developed footage offers the clearest look at an infamous piece of footage yet – and people were quick to react on social media. “Nooppe! thats just a dude on his way to a costume party!” one wrote. Another said: “This is the ai work we needed.” One more said: “Just some bro out for a stroll.” “So it’s a dude in a gorilla suit?” a comment read. Artificial intelligence, it seems, has the power to surprise us when we least expect it. It’s not the first time ‘Bigfoot’ has made headlines this year, after people claimed to have discovered a sighting via Google Maps. Have your say in our news democracy.

The Moon has been a subject of awe and fascination for millennia, with its shape-shifting powers and enigmatic dark side. And though it’s the one celestial body on which man has taken (small) steps, we still have big leaps to go in understanding its potential and uncovering its secrets. However, one hidden feature of the Moon has been unearthed by scientists and it’s very, very big, and very, very heavy. Buried beneath its South Pole-Aitken basin – one of the largest preserved craters in the Solar System – is a structure which weighs at least 2.18 billion kilogrammes and measures more than 300km (186 miles) in depth and 2,000km (1,243 miles) in length. Sign up for our free Indy100 weekly newsletter The researchers who made the discovery, all based in the US, posited that the “anomaly” could be made out of metal from the core of an asteroid or oxides from the crystallisation of a magma ocean. "One of the explanations of this extra mass is that the metal from the asteroid that formed this crater is still embedded in the Moon's mantle,” lead author Peter B. James, from Houston’s Baylor University, said in a statement shared with IFLScience. Illustrating just how gigantic this thing is, he went on: "Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That's roughly how much unexpected mass we detected.” The groundbreaking finding was made thanks to NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, which measures changes in the Moon’s gravitational field. Data collected by GRAIL can then be used to study the internal composition of our cratered companion. The South Pole-Aitken Basin has been at the centre of numerous investigations because of just how unique it is. The region offers clues both on the interior composition of our closest satellite and its history, and who knows what other mysteries it holds... Have your say in our news democracy.

Scientists have designed a new robot that people are dubbing a 'transformer' thanks to its ability to roll, fly, crawl, crouch, balance, and tumble its way through any terrain. Its adaptability is similar to that of a number of animals, including seals, meerkats, and chukar birds. The morphobot was created by the Northeastern University in the US, and will impact the future designs of response and rescue robots, as well as space exploration vehicles.

Would you sign up to live in isolation for a year, all in the name of furthering scientific research? Probably not, we’re guessing, but that’s exactly what four NASA volunteers have agreed to do over the next 12 months. The participants will live in an environment created to simulate conditions on the surface of Mars as part of NASA's Crew Health and Performance Exploration Analog for 378 days. The people involved are research scientist Kelly Haston, structural engineer Ross Brockwell, emergency medicine physician Nathan Jones and US Navy microbiologist Anca Selariu. Sign up to our free Indy100 weekly newsletter The simulation has been built at the Johnson Space Center in Houston, Texas, and will see the four volunteers undertake a series of tasks as part of the exercise. Data collected over the next 12 months will help to inform future missions to send astronauts to Mars. During that time, the guests will take part in activities such as crop growing as well as simulated spacewalks and other operations. The 3D-printed hub they’ll spend their time in contains a kitchen, sleeping areas, two bathrooms as well as work and recreation spaces. The mission will also see the guests faced with simulated obstacles, which are designed to test responses to equipment failure, communication delays and other issues. Speaking at a recent briefing, the mission's principal investigator at NASA Grace Douglas said: “Thank you all for your dedication to exploration. Our best wishes go with you." Haston also spoke, calling her fellow participants an "amazing group of dedicated individuals who feel very passionate about space exploration and science." "The crew has worked so hard this month to get ready for this mission," Haston added. "It has been very special to be a part of such a tremendous group of scientists and specialists from a diverse set of backgrounds working together to bring CHAPEA 1, the first of three missions, to reality."

It turns out that human ancestors and dinosaurs could have actually co-existed, according to new research. Scientists have produced a study which suggested that placental mammals were around before the asteroid that brought an end to the Cretaceous period hit Earth 66 million years ago. A new paper published in the journal Current Biology claims that fossil records of placental mammals suggests that our ancestors roamed the Earth before the extinction event, and later flourished due to the lack of competition from dinosaur species afterwards. According to the research, primates evolved shortly before the asteroid hit. Sign up to our free Indy100 weekly newsletter Lead author Emily Carlisle of Bristol’s School of Earth Sciences said: “We pulled together thousands of fossils of placental mammals and were able to see the patterns of origination and extinction of the different groups.” Carlisle added: “Based on this, we could estimate when placental mammals evolved.” “The model we used estimates origination ages based on when lineages first appear in the fossil record and the pattern of species diversity through time for the lineage,” co-author Daniele Silvestro from the University of Fribourg shared. While we don’t have a full picture of what human ancestors looked like at that time, it’s thought they “were small and squirrely”. Carlisle said: “Unfortunately we don’t know what our placental mammal ancestors would have looked like back then. “Many of the earliest fossils of placental mammals are quite small creatures such as Purgatorius – an early ancestor of primates – which was a small burrowing creature a bit like a tree shrew. So it’s likely that many of our ancestors were small and squirrely.” Have your say in our news democracy.

The online gaming world has a new obsession, with a game called Only Up where you simply have to keep climbing up a series of random objects until you reach space. The game sounds relatively straightforward as anyone who has even the most basic concept of videogames knows how to climb up various structures. However, Only Up does not make the game easy for players as the seemingly infinite amount of objects range from pipes, bridges and trampolines but even the slightest of mistakes can end in disaster sending the players plummeting all the way back to the start of the game. Only Up was developed by SCKR Games and released in May 2023. It is available to play on Steam for the price of £8.50 ($10.80). Sign up to our free Indy100 weekly newsletter The game has gone viral thanks to high-profile streamers such as Adin Ross, Hasan Piker and iShowSpeed playing the game on their respective streams. iShowSpeed, who has 17 million followers on YouTube, attempts to play the game have proved to be particularly entertaining. At one point he lost 8 hours of progress. Thankfully, while playing the game on Tuesday the 18-year-old was able to complete the game in just under 5 hours. The most impressive run on the game so far has come from streamer Shade managed to find a glitch which allowed him to complete it in just 33 seconds. Whether you want to complete the game properly or use the glitch is your call but have fun regardless. Have your say in our news democracy.

A man known for flying 4,000 miles to track down a thief who stole his AirPods is at it again – and this time, he’s baring all. With artificial intelligence technology on the rise, former Apprentice contestant, Lewis Ellis, is on a mission to find out if robots are going to come for our jobs. In a bizarre experiment, the 32-year-old, who is no stranger to unusual projects – having previously auctioned off his bum cheek for the highest bidder to choose a tattoo – he used ChatGPT to re-create an image for a billboard. And the result is hilarious. The giant billboard, featured at Victoria Warehouse in Lewis' hometown of Manchester, shows the entrepreneur stark naked – as a mermaid. Sign up to our free Indy100 weekly newsletter He used the famous Burt Reynolds Cosmo centre-fold for the main image and asked ChatGPT to “create the content”. ”Whatever it creates, that goes live,” Lewis says in a YouTube video. “I’m not sure if it’s is a good idea, I’m not sure if it’s going to be a complete waste of time but I guess we’ll find out.” Measuring in at 17.6m x 17.4 billboard, it is believed to be the second largest in Europe – however Lewis believes it is the “world’s largest AI-generated billboard. The Apprentice star photoshops his face and tattoos onto the nude Reynolds. The billboard went live at 9am on Wednesday (21 June) and… it’s definitely interesting. Lewis said: ”I was silly to assume that AI would pull it together for me – I won’t really have to do much. ”Turns out it's way harder than I thought. ”And it looks so bad.” The sorry-looking AI generated advert morphed the image of Lewis and Burt Reynolds into the sea creature. In the background, there is a cartoon drawing of a lighthouse and beach. The sign reads: “Feast your eyes on this tragic masterpiece. ”The world’s largest AI-generated billboard. ”AI is going to take over the world. ”That may be true… but it’s not going to be today.” The billboard ad is a recreation of his company, Hussel Marketing’s previous marketing campaign. Lewis took his inspiration for the experiment from the likes of McDonald's, Burger King and Subway, with the brands using ChatGPT for recent ads. To make it even harder, he gave himself just 24 hours to complete the challenge. The entrepreneur certainly isn’t shy in pushing the boundaries of what is possible and using technology to do so. In the past, he has shelled out £2,300 on flights, accommodation and food to fly 4,000 miles to track down his headphones, saying his mum describes him as “mental”. He told Jam Press: “We had no real plan but just hoped to find them again. “The fact you can track tiny headphones around the world is unbelievable. “I didn’t really expect to get them back and I joked that flying to Doha to get them is the pettiest thing I’ve ever done. “But it’s just great that we managed to find them – and now I don’t need to buy a new pair!” What does the marketing guru have up his sleeve next? It’s anyone’s guess. But one thing is certain – AI bots aren’t going to take over his job just yet. Have your say in our news democracy.

Pasta lovers are often guilty of draining their pasta water down the sink before adding sauce. But there is an important reason to save your pasta water and it is pretty scientific. Because pasta is made of flour, it releases starch into the cooking water as it boils, creating a white, cloudy liquid that emulsifies sauces it is added to. Emulsification is the process of blending two liquids that would otherwise repel each other ― in the case of pasta, it’s oil and water ― into a smooth, inseparable mixture. Sign up to our free Indy100 weekly newsletter Starchy pasta water is also a thickener, so saving some and mixing it into sauce creates something creamy and thick that won’t ever separate. This makes for a better sauce, so if you ladle some pasta water out before draining the rest you are going to be giving serious chef vibes. With that said, it is time to impress everyone you ever cook for again - just from the simple act of saving a small bit of water. Have your say in our news democracy.

The meaning of life is the ultimate mystery – why do we exist? And is there a point to… well… anything? These are questions to which we may never find answers, but at least we can define what “life” means in scientific terms. And yet, our understanding of what life is is changing all the time, thanks to space exploration. As scientists continue to hunt for life beyond our own world, biologists are having to rethink the meaning of the word “life” itself. Sign up for our free Indy100 weekly newsletter Generally, biologists explain “life” as connoting a self-sustaining chemical system which is capable of performing functions such as eating, metabolising, excreting, breathing, moving, growing, reproducing, and responding to external stimuli. This definition works pretty well here on Earth (although there are some important exceptions, such as viruses), but experts have pointed out that if life exists elsewhere in the universe, it may not display the same properties that we’re used to. Indeed, it might be unrecognisable as life as we know it (forget those little green men). In which case, how will we spot it if it ever crosses our path? Astrobiologist Sara Imari Walker and chemist Lee Cronin think they’ve come up with a solution. The pair are now arguing that highly complex molecules found in all living creatures can’t exist thanks purely to chance. Therefore, they say, the universe must have a way of creating and reproducing complex information and retaining a “memory” of all of this.. In an interview with New Scientist, Walker, of Arizona State University, explained their radical idea on how objects come into existence. The concept, known as Assembly Theory, explains why certain complex objects have become more abundant than others by considering their histories. If the theory proves correct, it will redefine what we mean by “living” things and show that we’ve been going about the search for extraterrestrial life all wrong. In the process, we could even end up creating alien life in a laboratory, she stressed. In her discussion with New Scientist, Walker pointed out: "An electron can be made anywhere in the universe and has no history. You are also a fundamental object, but with a lot of historical dependency. You might want to cite your age counting back to when you were born, but parts of you are billions of years older. "From this perspective, we should think of ourselves as lineages of propagating information that temporarily finds itself aggregated in an individual." Assembly theory predicts that molecules produced by biological processes must be more complex than those produced by non-biological processes, as Science Alert notes. To test this, Walker and her team analysed a range of organic and inorganic compounds from around the world and outer space, including E. coli bacteria, urine, meteorites and even home-brewed beer. They then smashed up the compounds into smaller pieces and used mass spectrometry to pinpoint their molecular building blocks. They calculated that the smallest number of steps required to reassemble each compound from these building blocks was 15. And whilst some compounds from living systems needed fewer than 15 assembly steps, no inorganic compounds made it above this threshold. "Our system … allows us to search the universe agnostically for evidence of what life does rather than attempting to define what life is," Walker, Cronin, and others wrote in a 2021 Nature Communications article. The handy thing about this building block system – which they’ve dubbed the “'molecular assembly index” – is that it doesn’t rely on carbon-based organic materials to be identified. In other words, an alien could be made of entirely different stuff entirely and we’d still be able to spot it as life using the index. It also works regardless of what stage of “life” an extraterrestrial being is in – whether it is still in its infancy or has moved into a technological stage beyond our understanding. That’s because all of these states produce complex molecules which couldn’t exist in the absence of a living system. If all of this is hurting your head, let’s just get back to the basics: if there is a secret to life, it might all be down to what we do, not what we are. Have your say in our news democracy.

New findings have suggested that adding sensors to supermarket trolleys could save people’s lives. Scientists investigated whether installing electrocardiogram (ECG) sensors – designed to check the heart’s rhythm – on the handles of supermarket, trolleys could identify shoppers with atrial fibrillation, which causes an irregular and often abnormally fast heart rate. The sensors would detect heart conditions that put them at increased risk of stroke. The researchers said that over the course of two months, they identified 39 people who were unaware that they had the condition. Ian Jones, professor of cardiovascular nursing at Liverpool John Moores University, who led the study, said: “That’s 39 people at greater risk of stroke who received a cardiologist appointment.” He added: “This study shows the potential of taking health checks to the masses without disrupting daily routines.” It is estimated that around 1.5 million people in the UK have atrial fibrillation, contributing to one in five strokes. The condition is treatable, but at least another 270,000 people in the UK remain undiagnosed and unaware, according to the British Heart Foundation. Sign up for our free Indy100 weekly newsletter There are wearable devices that can also spot irregular heartbeat but this would also require people to take responsibility and wear the device. Professor Jones said: “Nearly two-thirds of the shoppers we approached were happy to use a trolley, and the vast majority of those who declined were in a rush rather than wary of being monitored. “This shows that the concept is acceptable to most people and worth testing in a larger study.” He added: “Checking for atrial fibrillation while people do their regular shopping holds promise for preventing strokes and saving lives. “A crucial aspect is providing immediate access to a health professional who can explain the findings and refer patients on for confirmatory tests and medication if needed.” The findings were presented at ACNAP 2023 conference organised by the European Society of Cardiology (ESC).
