The world’s two richest tech bros have continued their war of words, after Elon Musk called Mark Zuckerberg a “chicken” for appearing to call off a planned fight between the two. Yesterday, Zuckerberg said he is moving on from a rumoured cage fight with Twitter owner Musk, claiming the Tesla boss “isn’t serious”. Musk responded: “Zuck is a chicken.” The rival billionaire tech bosses seemingly agreed to a brawl in June when Musk tweeted that he was “up for a cage fight”. Zuckerberg, who manages Facebook and Instagram, took a screenshot of Musk’s tweet, replying “send me location”. Musk, owner of social media platform X, formerly named Twitter, appeared to suggest the fight would be held in an “epic location” in Italy. Sign up to our free Indy100 weekly newsletter He outlined streaming options and an ancient setting for the proposed event, claiming he had spoken to Italian Prime Minister Giorgia Meloni. However, Zuckerberg yesterday wrote on Threads, his own social media platform: ”I think we can all agree Elon isn’t serious and it’s time to move on. “I offered a real date. Dana White (UFC boss) offered to make this a legit competition for charity. “Elon won’t confirm a date, then says he needs surgery, and now asks to do a practice round in my backyard instead. “If Elon ever gets serious about a real date and official event, he knows how to reach me. Otherwise, time to move on. I’m going to focus on competing with people who take the sport seriously.” Despite Musk claiming it was actually Zuckerberg backing down, some users of his own platform agreed that the latter might have a point. “Just need to give him a date,” one person said. Another wrote: “Not sure why you think so. He keeps trying to get a time and you keep postponing. Right?” Have your say in our news democracy.

Twitter has lost its head of trust and safety amid ongoing criticism of the site’s protections against harmful content. Ella Irwin said on Thursday that she had stepped down as the company’s head of trust and safety, a key role in ensuring that Twitter is able to avoid showing dangerous content and compromising relationships with advertisers. Ms Irwin, who joined Twitter in June 2022, took over as head of the trust and safety team in November when previous head Yoel Roth resigned. She oversaw content moderation. An email to Twitter returned an automated reply with a poop emoji. Irwin declined further comment and Musk did not immediately respond to a request for comment. Irwin’s departure comes as the platform has struggled to retain advertisers, with brands wary of appearing next to unsuitable content. Musk announced earlier this month that he hired Linda Yaccarino, former NBCUniversal advertising chief, to become Twitter‘s new CEO. Fortune earlier reported that Irwin’s internal Slack account appeared to have been deactivated. Since Musk’s acquisition, Twitter has cut costs dramatically and laid off thousands of employees, including many who had worked on efforts to prevent harmful and illegal content, protect election integrity, and surface accurate information on the site. Musk has promoted a feature called Community Notes, which lets users add context to tweets, as a way to combat misleading information on Twitter. The company is also facing increasing scrutiny from regulators over its moderation efforts. Twitter withdrew from a voluntary agreement with the European Union to tackle disinformation, while saying it was committed to complying with upcoming internet rules in the EU. EU industry chief Thierry Breton warned Twitter last week that it would not be able to avoid legal obligations in the EU after quitting the voluntary agreement.

Are your grandparents up very early in the morning, without fail? Well, it turns out there are scientific reasons why older people wake up earlier as they get older. It’s been revealed that in later life, the natural process of ageing leads to changes in the times the body approaches sleep. According to HuffPost, our approach towards resting and amount of sleep we require is down to both genetics and our age. Cindy Lustig, who is a professor of psychology at the University of Michigan, said: “Like most of the things that change with age, there’s not just one reason, and they are all interconnected.” Sign up to our free Indy100 weekly newsletter It’s all to do with the brain becoming less responsive as people age to factors such as sunlight, social cues and physical activity which indicate where in the day we are at any given time. “The wiring of the brain is likely not sensing... and responding to the inputs as well as it should because it’s an ageing brain,” Dr. Sairam Parthasarathy, the director of the Center for Sleep and Circadian Sciences at the University of Arizona Health Sciences, also told the publication. “These are all what we call time givers, or they give time to the brain,” he said. In other words, they help the brain sense where it is in the 24-hour circadian cycle. Younger people can more easily connect indicators like eating dinner with the idea of sleeping in the next few hours. However, that’s not as easy for older people to register naturally, especially as their vision tends to suffer in later life. “Interestingly, one of [the reasons] seems to be that the vision changes that come with age reduce the intensity of the degree of light stimulation that our brain receives, which plays an important role in ‘setting’ our circadian clock and keeping it on track,” said Lustig.
