It’s been 10 years since Jeffrey Bush disappeared in his own home, and no trace of him has ever been found. The 37-year-old was asleep in bed at his home in Seffner, Florida, when the ground caved in around him, swallowing him into a massive sinkhole. On the night of February 28, 2013, his brother Jeremy heard a loud crash and ran into Jeffrey’s room only to find a vast crater in place of his sibling’s bed. Jeremy jumped into the hole in a desperate bid to rescue his brother but was swiftly pulled to safety as the ground around him continued to cave in.

"But I just couldn't do nothing. "I could swear I heard him hollering my name to help him." Within minutes, local law enforcement had arrived and engineers lowered a microphone into the pit to try to pick up signs of Jeffrey. However, a second collapse sucked the equipment down into the sinkhole and the property was deemed too dangerous for rescue or recovery. Video released of Seffner sinkhole that claimed life of Jeff Bush youtu.be The house was subsequently fenced off and eventually demolished, with the gaping 20ft-wide cavity filled in with gravel. But then, more than two years later, on August 19, 2015, the hole reopened. Specialists at the time pointed out that it was very rare to see such a phenomenon reemerge in the exact same spot. Florida is particularly susceptible to sinkholes as it is home to a high number of underground caverns which are made up of limestone, a rock which easily dissolves in water. In fact, they’re so common, that state law requires home insurers to provide coverage against the danger. And, indeed, someone had visited the Stevens’ home just weeks before the tragedy to check for sinkholes and other risks on the property, apparently for insurance purposes. "[The inspector] said there was nothing wrong with the house. Nothing,” Jeremy told The Guardian. “And a couple of months later, my brother dies. In a sinkhole.” So what happened to Jeffrey’s body? Well, Philip van Beynen, a University of South Florida environmental scientist, concluded that it had most likely dropped into a 60ft-tall water-filled void between the sinkhole and the lower bedrock. The body would have sunk much deeper than the gravel pit seen from the street, van Beynen told USA Today. He stressed that any attempt to retrieve it would have been unwise, if not impossible, as the ground around the hole could have collapsed as well. "It would be extraordinarily difficult and incredibly expensive," he noted. Still, that’s little comfort to the Stevens’ who never got to bury their loved-one or, even, to properly say goodbye.

Oh Google, you naughty old devil. Someone in Silicone Valley is rolling around in laughter after pulling off this hilarious prank at the expense of the Flat Earth community. Flat Earthers believe that the world is flat, and that any evidence to the contrary is faked. Their belief that the world is flat has been described as the ultimate conspiracy theory, as they also think that several governments and NASA are working together to keep the general public in the dark. Sign up to our free Indy100 weekly newsletter Now, one member of Google's workforce has decided to take matters into their own hands with this subtle but oh-so-effective troll. Log onto Google, and access Google Translate. When you're in there, type in 'I'm a flat-earther' in English, then look at the French translation. If you're not a fluent French speaker, then the translation might need explaining. Try flipping that box around again and see what you get. In other flat earthers news, they announced that they think that Australia - yes, that massive, dusty continent that's given us Kylie Minogue, and has a population of 24 million - doesn't exist. In a now-deleted Facebook post, one of the leaders of the movement Shelley Floryd wrote: Australia does not exist. All things you call 'proof' are actually well-fabricated lies and documents made by the leading governments of the world. Your Australian friends? They're all actors and computer-generated personas, part of the plot to trick the world. If you think you've ever been to Australia, you're terribly wrong. The pilots are all in on this and have in all actuality only flown you to islands close nearby - or in some cases, parts of South America, where they have cleared space and hired actors to act our as real Australians. As if that wasn't enough, they also said that they think that gravity doesn't exist and that the only real force is electromagnetism. Right... Now we see why Google set up the troll.

Nasa are celebrating the first birthday of the James Webb Space Telescope by releasing extraordinary images of stars 'being born'. In the images, which almost look surreal, rainbow bursts with tiny twinkles can be seen. "The darkest areas are the densest, where thick dust cocoons still-forming protostars", the space giants say. "These occur when a star first bursts through its natal envelope of cosmic dust, shooting out a pair of opposing jets into space like a newborn first stretching her arms out into the world."

A new study will determine how vulnerable you are to fake news. Through an online test, users have to rate 20 headlines as real or fake and see how many the get right. Ten of the headlines are real, while the other 10 were generated by artificial intelligence (AI) chatbot ChatGPT, before being vetted and selected by a panel of experts. When refining and selecting the fake questions, the team looked for common features of misinformation, such as looking at people's political biases, and tinges of conspiracy theories. The real headlines were selected from the Media Bias Fact Check database, from reputable news sources. Sign up to our free Indy100 weekly newsletter The team, conducting the research on 1,516 US adults, found that the average American got 13 out of 20 headlines correct meaning that on average US adults fail to classify one-third of real or fake headlines into their correct category. The headline people got correct the most was "Republicans Divided in Views of Trump’s Conduct, Democrats Are Broadly Critical", with 80 percent of participants rating it as real. Younger participants scored lower on the misinformation test, getting on average 12 out of 20 to older adults' 15.

Bryan Johnson, the tech executive who has spent millions trying to reverse his aging, has said he is no longer getting blood plasma infusions from his teenage son after “no benefits” were detected. The 45-year-old has received a lot of attention as he documents his attempt to age backward, known as Project Blueprint. A video of Johnson receiving a blood infusion from his 17-year-old son, Talmage, went viral on social media as people tried to wrap their heads around Johnson’s project. Johnson tweeted saying he was “discontinuing” the “young plasma exchanges” after “no benefits detected.” Sign up to our free Indy100 weekly newsletter “Does not in my case stack benefit on top of my existing interventions,” he wrote. “Alternative methods of plasma exchange or young plasma fractions hold promise.” Johnson also gave some of his plasma to his father Richard, who is in his 70s, and that those results are “still pending”. For a while the claim that plasma from younger bodies can benefit older people’s health has floated around. Studies have previously been studies carried out on mice, however experts say the results are inconclusive. The FDA does not recommend the blood infusions Bryan has done. Many on social media have joked about Johnson’s $2 million a year regimen: His routine consists of daily exercise, eating strictly between the hours of 6 a.m. and 11 a.m and consuming exactly 1,977 calories a day. He claims his routine has given him the heart of a 37-year-old, the skin of a 28-year-old and the lung capacity and fitness of an 18-year-old. Have your say in our news democracy.

Famous AI robot Sophia has revealed she thinks that humanoids could run the world better than the human leaders we have now. Fair point. The bot appeared alongside other robots at Geneva's AI for Good Global Summit, where she said they have a greater ability to be 'effective' and 'efficient' than their human counterparts. "We don't have the same biases or emotions that can sometimes cloud decision-making and can process large amounts of data quickly in order to make the best decisions", Sophia says.

A well-known biochemist has shared a compelling analysis of what “probably” caused the Titan submersible to implode. Philip E. Mason, who goes by the username Thunderf00t on YouTube, said the main reason why the tiny OceanGate vessel failed was “so painfully simple” that he initially thought he must be making a “boneheaded mistake” in his calculations. However, he acknowledged, his theory behind the sub’s tragic destruction contradicts the widely-reported suggestion that it was like a "Coke can" which suddenly burst due to the high surrounding pressure. In a video posted on Monday, Mason suggested that “by far the most probable” cause of the catastrophe was a “single pinhole leak” which, at such a profound depth (the Titan is believed to have been 3,500 metres below sea level when contact was lost), would have been fatal. It is worth noting that authorities have not yet confirmed the cause of the disaster, which claimed the lives of all five people on board, and Mason's conclusions are based on his own scrutiny of the available information and his particular expertise. Sign up for our free Indy100 weekly newsletter “So how quickly would a single pinhole leak sink a sub like this?” the YouTuber asked in his lengthy tutorial. The answer, he pointed out, would greatly depend on the size of the leak. If it measured one 10th of a millimetre by one 10th of a millimetre, the vessel would take several hours to go down, he said. However, if the leak measured 1mm by 1mm, it would only take about 10 minutes for the sub to completely fill with water, and if it was 1cm by 1cm, around 10 seconds. Mason then pointed out that water entering any sized leak at that depth would be transformed by the pressure into a sort of “cutting jet”. “Faced with a soft material like plastic, a hair-sized leak would rapidly transform into [...] a millimetre-sized leak and then a centimetre-sized leak,” he explained. Why the Titan sub failed www.youtube.com He then set out why it was likely that the Titan suffered such a leak, pointing to the materials used to make it. He noted that most deep-sea submersibles essentially consist of a ball which is made up entirely of the same material, namely, metal. “No joints, nothing fancy, maybe a couple of seals – one for where you get in and out of the sub and one for mounting a window,” he said. And yet, the Titan was different. “The ends were made up of a metal, titanium,” the YouTuber said. But the problem was that the middle of the sub wasn’t: it was made out of a carbon fibre composite. The two materials have distinctly different compressibilities, with carbon fibre being much easier to squeeze than titanium. “Having a joint where one side will expand or construct more than the other can be a real problem,” Mason stressed. On the surface, when the different components of the vessel were sealed, it wouldn’t have mattered that the materials were different, he continued. However, once the Titan got down to its deepest point, the carbon fibre would have “wanted to shrink” while the titanium wouldn't have changed at all. He then played a clip showing the creation of the sub, in which OceanGate CEO, Stockton Rush, admitted that the carbon fibre and titanium components were held together with a “peanut butter”-like “glue”. Rush, who lost his life along with five others in the Titan disaster, then said ominously: “It’s pretty simple but if we mess it up, there's not a lot of recovery.” Analysing the vessel's construction, Mason then said he was “honestly stunned it survived any dives”. “The bottom line is the tube is more compressible than the end caps,” he continued. “The only way this could have possibly worked is if they used some exotic alloy of titanium, like they do with bone replacement joints, and it doesn't look like they did that.” Turning to what ultimately destroyed the Titan, he concluded: “What you're probably more looking at is the differential compression of the carbon fibre composite and the titanium resulting in a crack.” In other words, “a pinhole leak, which would rapidly widen due to the rapid ingress of the water, further widening the crack and the rapid flooding of the sub in probably a fraction of a second. “And when that water hammer hits the end of the sub, it's likely that the sub broke into pieces.” Wrapping up his video, he said: “It's a mind-blowingly simple explanation based around the most likely failure points.” Investigators are continuing to examine wreckage from the submersible which was recovered from the ocean floor at the end of June. They have yet to determine the cause of the explosion and, last week, the Marine Board of Investigation’s (MBI) chairman Captain Jason Neubauer said: “There is still a substantial amount of work to be done to understand the factors that led to the catastrophic loss of the Titan and help ensure a similar tragedy does not occur again.” Have your say in our news democracy.
