The Duke and Duchess of Sussex have urged social media companies to reduce the amount of harmful content children can see online to protect their mental health. Harry and Meghan made the remarks at a mental health awareness festival run by non-profit Project Healthy Minds in New York on Tuesday. They are visiting the city for the first time since being caught up in what they called a catastrophic car chase there in May. The royal couple, who have spoken about their own mental health challenges in the past, took part in a panel discussion alongside US surgeon general Vivek Murthy moderated by NBC host Carson Daly, who has previously spoken of his struggles with anxiety. The event, on World Mental Health Day, has been co-ordinated by the duke and duchess’s Archewell Foundation. The couple called on social media firms to adopt better content moderation policies and tweak apps which can prove addictive for youngsters. They spoke after hearing from parents who have lost children to mental health issues linked to social media use. The duke urged tech bosses to “stop sending children content you wouldn’t want your own children to see”. The duchess said she and her husband are focusing on what they can do behind the scenes to make social media use “safer, better and more positive” and that the couple have spoken to tech executives about the issue. She added: “People are getting hurt – and people, specifically children, are dying. “A year ago we met some of the families, not all of them. At that time, it was impossible to not be in tears as I’m sure so many of you have been today hearing these stories. “As parents, our kids are really young – they’re two-and-a-half and four-and-a-half – but social media is not going away. “I think by design, there is an entry point that is supposed to be positive, in creating community and something has devolved, and there is no way to hear that and not try to help these families have their stories be heard.” In the UK, the Princess of Wales gave a speech to young people gathered in Birmingham for a day of workshops and discussions to mark World Mental Health Day, with her husband in the audience. Harry and Meghan were all smiles when they visited the Marcy Lab School in Brooklyn, New York earlier on Tuesday. The school’s website claims it is the “alternative to college that you have been looking for” for people looking to start a career in tech. Harry was applauded when he told a meditation class that “if one of you starts to go quiet, doesn’t show up, you need to find out why” and added “remember to have fun”. Meghan, who was wearing a varsity letterman jacket given to her at the Robert Clack School in Essex in March 2020, told a class she wishes her children were with her but they are “doing well”. Students later rushed to take pictures with the royal couple before the school’s co-founder Reuben Ogbonna joked “back to class, everyone”.

MIAMI--(BUSINESS WIRE)--Jul 25, 2023--

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.
