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.

Scientists have found an array of “dashes” within our universe, all arranged in an unexpected pattern. The vast structures are lying in the middle of our Milky Way galaxy and point towards the black hole at its core. There are hundreds of them, each five to 10 light-years long, researchers say. “It was a surprise to suddenly find a new population of structures that seem to be pointing in the direction of the black hole,” Northwestern University’s Farhad Yusef-Zadeh, who led the research. “I was actually stunned when I saw these. We had to do a lot of work to establish that we weren’t fooling ourselves. And we found that these filaments are not random but appear to be tied to the outflow of our black hole. By studying them, we could learn more about the black hole’s spin and accretion disk orientation. It is satisfying when one finds order in a middle of a chaotic field of the nucleus of our galaxy.” Scientists have no confirmed explanation for where the structures came from, and much about their existence remains a mystery. But one possible explanation is that they were thrown out from after some activity a few million years ago. In the early 1980s, Professor Yusef-Zadeh found a set of gigantic, one-dimensional filaments hanging across our galaxy, near Sagittarius A*, the black hole at the heart of the Milky Way. The new filaments were previously undiscovered, and are much shorter and lie across, spreading out from the black hole. “We have always been thinking about vertical filaments and their origin,” he said. “I’m used to them being vertical. I never considered there might be others along the plane.” The research is described in a new paper, ‘The Population of the Galactic Center Filaments: Position Angle Distribution Reveal a Degree-scale Collimated Outflow from Sgr A* along the Galactic Plane’, published in The Astrophysical Journal Letters.
