A scientist has broken the world record for living underwater after spending 74 days living in a habitat 30 feet (9 metres) below a Florida lagoon. Former naval officer Dr Joseph Dituri is the first person to live that long that far underwater without depressurisation, with plans to remain in Jules’ Undersea Lodge in Key Largo until 9 June as part of a 100 day mission dubbed Project Neptune 100. The mission combines educational outreach with medical and ocean research, with scientists keen to see what impact sustained exposure to such pressure will have on the human body. One hypothesis is that the increased pressure – roughly 1.6-times that of the surface pressure – will lead to improvements in health, while also potentially having an impact on key indicators related to disease and longevity. “We know for sure that when you’re exposed to about half the pressure that I am right now, you double the number of circulating stem cells,” Dr Dituri told The Independent via video chat in April. “I will have longer telomeres – potentially reversing ageing – and I will also gain bone density and muscle when I’m down here.” Scientists also estimate he may lose around an inch in height during the mission due to the pressure exerted on his body – in the same way that astronauts grow around 3 per cent taller after spending time in the weightlessness of space. Dr Dituri’s 74th day residing in the underwater lodge was similar to previous days spent there since he submerged on 1 March. The university professor, who also goes by the moniker “Dr. Deep Sea,” ate a protein-heavy meal of eggs and salmon prepared using a microwave, exercised with resistance bands, did his daily pushups and took an hour-long nap. Unlike a submarine, the lodge does not use technology to adjust for the increased underwater pressure. The previous record of 73 days, two hours and 34 minutes was set by two Tennessee professors – Bruce Cantrell and Jessica Fain – at the same location in 2014. “The record is a small bump and I really appreciate it. I’m honoured to have it, but we still have more science to do,” Dr Dituri said. “The idea here is to populate the world’s oceans, to take care of them by living in them and really treating them well.” While he says he loves living under the ocean, there is one thing he really misses. “The thing that I miss the most about being on the surface is literally the Sun,” he said. “The sun has been a major factor in my life – I usually go to the gym at five and then I come back out and watch the sunrise.” During his time underwater, Dr Dituri also claims to have discovered a brand new species. “We found a single-cell ciliate, a single-celled organism that we believe is a brand new species to science,” Dr Dituri said. “People have dived in this area thousands and thousands of times – it’s been here, we just didn’t look.” Additional reporting from agencies Read More Woman talks to past self in ‘trippy’ conversation after feeding childhood journals to AI Nearly half of all internet traffic is now bots, study reveals ChatGPT is finally connected to the web 75% of Irish data watchdog’s GDPR decisions since 2018 overruled – report

SANTA MONICA, Calif.,--(BUSINESS WIRE)--May 16, 2023--

MGM Resorts has shut down some of its systems as a result of a "cybersecurity issue," according to a company social media post on Monday.

Apple has announced a surprise event, at which it is expected to unveil new Macs. The event is unusual in a number of ways, including its much later start than Apple’s regular events: it will begin at 5pm local pacific time, or midnight in the UK. Apple events almost always begin at 10am local time, and it did not give any indication of why it had changed its time. It will also take place notably late in the year, on 30 October. Apple appeared to reference the proximity to Hallowe’en in its invitation, which used the title “Scary fast”. It will also be entirely virtual, with no in-person attendance. Apple switched to fully virtual events during the pandemic, but has since opened up physical attendance as restrictions have lifted. Unlike many recent Apple events, it is unclear what exactly the company is planning – though Apple’s website used the “Finder” icon from the Mac operating system, all but confirming a focus on its computers. Apple seems likely to introduce a new version of its iMac, which was last updated in April 2021 and is now far behind all of the rest of Apple’s line-up. It still uses Apple’s M1 chip, and the event will presumably at least bring it up to speed with the existing M2 processors. The company might unveil its first M3 processors, however. Apple’s first M2 computers arrived last summer, inside updated MacBook Air and MacBook Pro models, and so those computers could also be updated with the latest generation. Some reports have also suggested that Apple could be planning an update for its most high-end and expensive 14- and 16-inch MacBook Pro, too. Those were overhauled earlier this year, however, with the introduction of the M2 Pro and M2 Max, meaning that any new update might be less likely or could be more minor. Recent weeks brought rumours that Apple was planning to update at least some of its iPads. The rumoured launch day only brought a new Apple Pencil, however – which may mean that the iPads were delayed for the upcoming event, or may mean that Apple opted not to make any changes to the iPad and released the Apple Pencil to clear the way for its new Macs. The latest launch comes the month after Apple held another live event – at its usual time – to launch the new iPhone 15 and other products.
