CITY OF INDUSTRY, Calif.--(BUSINESS WIRE)--Jun 8, 2023--

Great white sharks are displaying unprecedented behaviours, and experts can’t explain why. One of the ocean’s greatest apex predators has been entering the twilight zone way beneath the surface of the ocean, and far beneath the areas they normally feed in. The twilight zone, also referred to as the mesopelagic zone, is the area 200 to 1,000 metres down below the surface which is at least partly permeated by sunlight. The midnight zone, meanwhile, is found 1,000 to 3,000 metres down and is impenetrable to sunlight. Now, a new study published in the journal PNAS offered insight into the behaviours of 344 tagged predatory fish including great white sharks. Scientists would usually expect the creatures studied to dive to the deep scattering layer (DSL), which is full of small fish and other ocean life forms and therefore attracts more predators than other levels. However, there was also evidence that suggested predators dove down far deeper than the DSL, and scientists don’t know why. According to the research, great white sharks dive down to as deep as 1,128 metres. Camrin Braun is assistant scientist at the Woods Hole Oceanographic Institution and study lead. Braun told Live Science: "How, when, where they access the deep ocean certainly varies, but the clear anecdotal answer is that the deep ocean seems like an important habitat regardless of the predator species. It's clear there are good reasons for these animals to dive deep, otherwise why would they all do it? "There's good evidence for some species/situations in which diving deep is clearly for foraging," Braun added. "So that supported our expectation. However, we also find several cases where we can pretty definitively say the use of the deep ocean is not for feeding – or if it is it represents a totally different kind of predator-prey interaction or mysterious prey resource." The study could suggest that the twilight zone could be far more important to great white sharks and other predatory fish than previously thought. "If it turns out that there is indeed more biomass in the twilight zone than in all current marine capture fisheries combined then it's possible to imagine a kind of mesopelagic 'gold rush' to catch and use this biomass," Braun said. "There are many 'ifs' in this chain and many issues in making mesopelagic fishing feasible but it seems that biomass may be important for predators. Therefore, we really need to better quantify those links between predators and mesopelagic biomass before we can sustainably harvest/use those resources.” Sign up for our free Indy100 weekly newsletter How to join the indy100's free WhatsApp channel Have your say in our news democracy.

Referees could be replaced by robots within the next 30 years, an expert in the field believes. Artificial intelligence is already prominent in officiating, with the use of VAR and goalline technology, but it is expected to heavily increase in the future. With more high-quality data available, it could be possible for matches to be officiated by an AI-powered machine, taking away the need for an on-field human referee. “Computer vision will be more and more effective in the next few years and the number of cameras on the pitch will only increase,” Aldo Comi, chief executive of leading global football analytics provider Soccerment, told the PA news agency. “The amount of data that is tagged and the quality of the models that are trained with that data will increase exponentially and thanks to that you will have AI models that can make refereeing decisions on the back of what they see on the pitch. “So we might get to the point where we don’t need a referee at all. “Before that, you will maybe have a referee but not linesmen, maybe they will be the first to disappear from the game. And you will have the referee connected to the virtual assistant, guiding them to make better decisions. “Ultimately in a matter of 20 or 30 years probably the referee will be just an AI. I am not saying this is positive, I’m just saying it is likely to happen.” The increase of AI and machine learning in football will not be restricted to officiating and it is already present in the game. The use of data analytics have helped the likes of Brighton and Brentford disrupt the established Premier League hierarchy as they have unearthed high-quality signings which they have sold on for significant profits. But the improvement in the integration of data could see managers using a virtual coach to help them with team selection and tactics. “AI can become a source of new ways of thinking about the game in the next few years,” Comi added. “If you give AI enough high-quality data, you will have the possibility to have a virtual assistant, which will have a better understanding of what is going on the pitch. Ultimately in a matter of 20 or 30 years probably the referee will be just an AI Aldo Comi, CEO of data analtyics company Soccerment “By having the data analysed by AI you can train models to better understand what will happen in the future, for example understanding the probabilities of what is happening in the next five or 10 minutes. “By having this predictive analytics, the AI can give you a so-called prescriptive analytics. It says, ‘Things are expected to go this way, in order to improve your chances I have 10 ideas’. “That could be swapping two players or changing the structure of the team. “The things that the AI suggests will be filtered by the assistant coach and then pass on the information to the manager and it will be up to him to accept. “There will be AI, but not replacing professionals, but it is more of a high-quality support. The clubs that can get this sport will outperform the ones that refrain from having it.” Comi, whose company serve several Serie A and Serie B clubs, says that people will need to learn to trust AI but the evidence of it working is already out there. He added: “It will take time to trust, but in the same way with data analytics, there are enough positive cases to say that you can out-perform the others, we have seen it with Brentford and Brighton. “The advantage that AI can give you is X times more important than data analytics.” :: Soccerment has launched a new platform, xvalue.ai, which has introduced never seen before metrics such as Gegenpressing Intensity (GPI), Expected Offensive Value Added (xOVA), Gegenpressing Efficiency (GPE) and BuildUp Disruption Percentage (BDP%), providing users with more data insights than ever before.

Tucker Carlson’s Twitter show has reportedly suffered a significant drop in viewership since his debut episode of Tucker on Twitter. Journalist Matt Binder tweeted the number of video views the former Fox News host has garnered since his Twitter show began on 6 June. While his first show attracted 26.7m video views, the subsequent episode attracted half as many: 13.9m. His most recent episode, his eighth, only garnered 3.8m video views, according to Binder. It counts as a “view” if someone watched the video for more than two seconds. Media Matters senior fellow Matthew Gertz also calculated the views per posts, noting a significant decline since Carlson’s show launched. Although the first post generated 120m views, his most recent only generated 8.6m. Carlson was fired from Fox News — for reasons that reportedly remain unknown to the network’s former superstar. In March, one month before his termination, Carlson averaged 3.3m viewers per show, according to Nielsen. The social media platform’s views aren’t necessarily equivalent to broadcast news views. According to Twitter, a post view is tallied when “anyone who is logged into Twitter who views a Tweet counts as a view, regardless of where they see the Tweet (e.g. Home, Search, Profiles, etc.) or whether or not they follow the author. If you’re the author, looking at your own Tweet also counts as a view.” The views are also not always from unique viewers, the social media giant noted. Carlson may have joined Twitter at a particularly turbulent time for the platform, after Elon Musk took over. Mr Musk’s policies have sparked a lot of criticism from users as well as a Congressional investigation. Things may have gotten more complicated last week after the “Twitter killer” app was introduced. Threads, a rival platform created by Mark Zuckerberg, comes as many fed-up Twitter users are threatening to leave Mr Musk’s platform. “I don’t know why I was fired. I really don’t. I’m not angry about it. I wish Fox well,” Carlson said during a recent podcast interview. Fox News reached a massive $787m settlement with Dominion Voting Systems after spreading false statements about the voting machine company. His former employer sent him a cease-and-desist letter, to which Carlson’s lawyer replied, he will “not be silenced.” The Independent has reached out to Carlson and Twitter for comment.
