Meta Sued in Australia Over Alleged Harm to Children
Social media giant Meta was hit with a class action lawsuit in Australia on behalf of children and teenagers who allegedly suffered harm over the addictive design features and exposure to harmful content on its platforms Facebook and Instagram.
Australian law firm MinterEllison filed the class action in the country’s Federal Court on Oct. 9. The firm announced the suit on Wednesday, saying it seeks to “recover compensation for both current and former users” of the two Meta social media platforms.
The class action, funded by Sydney-headquartered Litigation Lending Services, was brought in the names of eight unnamed lead applicants. Australia’s Federal Court on Monday ordered a gag on reporting any information that could reveal the applicants’ identities and their statements of claim.
“This proceeding raises important questions about the design and operation of social media platforms and their impact on children and teenagers in Australia,” MinterEllison Partner William Nolan said in its press release. “Those questions will now be considered through the Federal Court process.”
TIME reached out to Meta for comment. A spokesperson told Reuters: “We are aware of this claim and we will defend ourselves vigorously.”
The Australian government, which enforced the world’s first social media ban for children under 16, is also set to take action against Meta and other social media companies. In a Bloomberg interview published Tuesday, Communications Minister Anika Wells, a 2026 TIME100 Next honoree, said that the government expects to bring Meta’s Facebook and Instagram, ByteDance’s TikTok, Snapchat, and Google’s YouTube to court for allegedly failing to comply with the country’s laws.
U.S. parallels
The Australian class action follows several civil victories against Meta in the U.S. In March, a Los Angeles jury ordered Meta and Google to pay $6 million in damages to a 20-year-old plaintiff in a bellwether social media addiction trial. In August, a New Mexico court ordered Meta to pay more than $900 million and introduce a slew of reforms to its platforms, including rigorous age verification, time limits for users under 18 years old, and enhanced protection against sextortion and child sexual exploitation. The same month, Meta agreed to pay up to $18 billion to settle a nationwide lawsuit that alleged its platforms were “addictive” by design and harmed children.
Rob Nicholls, a senior researcher at the University of Sydney with expertise on digital regulations, tells TIME in an email that he was “not surprised” with the class action, given the cases in the U.S.
“The U.S. lawsuits were primarily concerned with negligence,” Nicholls tells TIME. “It’s likely that in Australia the suit will be both negligence and the consequences of the supply of an unsafe product.”
Regulatory enforcement
Australia has led the way in trying to rein in social media platforms in the name of child safety. Last year, it enforced a blanket ban on children under 16 from having social media accounts, a move that other countries have followed.
The effort, however, has been criticized by some, including politicians and digital rights advocates, for not being aggressively enough enforced since the ban took effect in December 2025. The latest data from the country’s online regulator, eSafety, shows that 42% of children aged 10 to 15 still own a social media account.
In a podcast published Thursday, Wells, the Communications Minister, said there was a “great initial response” with 5 million accounts deactivated, but that has since “tapered off.” She added that the eSafety Commissioner believes the five platforms in particular could be doing more to comply with the law and the Commission is investigating potential violations.
Asked why there haven’t been any fines yet, Wells said: “Unfortunately, this isn't a police officer on duty pointing a speeding radar at a car and issuing an on-the-spot fine. This is asking the eSafety Commissioner, our independent regulator, to take on some of the biggest, richest, most resourced companies in the world.”
In September, the Australian government increased the fines for noncompliant social media firms. Failing to take “reasonable steps” to prevent underage Australians from creating or keeping accounts could incur a maximum penalty of 109.2 million Australian dollars (around $76 million).
But speaking to Bloomberg, Wells pointed to the multi-billion-dollar settlement Meta agreed to in the U.S. and said, “I’m not convinced that any particular dollar value is going to change it.” For her, the policy should be measured on how it creates cultural change. “And cultural change,” she said, “takes time.”

Задача сложная, времени мало: какие упрощенные модели мы использовали для тепловых расчетов BBU
Система охлаждения — это камень преткновения для современных вычислительных систем с большим тепловыделением. Когда переход на жидкостное охлаждение невозможен, а увеличивать радиатор уже некуда, приходится искать другие способы, как не дать оборудованию перегреться.
Сегодня разработка вычислительных систем включает обязательное математическое моделирование, но на этапе проработки конструкции полноценные расчетные модели требуют огромных временных ресурсов. Упрощая геометрию и модели компонентов, можно ускорить процесс, но есть и обратная сторона: если упростить их слишком сильно, есть риск сделать неверные выводы о (не)работоспособности конструкции и «закопать» удачную идею на раннем этапе проектирования. А еще нужно понимать ограничения, которые накладывает использование упрощенных моделей, и знать, как свести их к минимуму.
Меня зовут Александр Воробьев, я ведущий инженер по моделированию в YADRO. Сегодня расскажу, как мы моделировали систему охлаждения BBU и какой подход помог ускорить этот процесс. Решения, которые я опишу, универсальны — сможете использовать их в своих проектах.

Гораздо реже вспоминают, что с настройками по умолчанию кнопка завершения работы в Windows не выключает систему полностью, а ноутбук в рюкзаке иногда только делает вид, что находится в спящем режиме.

Frustration with a sprawling fraud scandal has cut Peggy Flanagan’s poll lead – could ex-NFL reporter Michele Tafoya win a first statewide election for Republicans in 20 years?
As Democrats fight to regain control of the US Senate, hopes are rising in states – from Kansas to Texas – where they have not prevailed in decades. But in Minnesota, where Republicans have not won statewide election since 2006, the contest for an open Senate seat is closer than expected.
Should Peggy Flanagan – the state’s Democratic lieutenant governor – win the election, she will be the first Native American woman to serve in the US Senate. But history has not yet been made. The closely watched Cook Political Report shifted its rating on the race this week from “likely Democrat” to “lean Democrat”.

Agency declines to reveal in which state latest measles death occurred as it delays reporting other measles deaths
The US Centers for Disease Control and Prevention (CDC) added a third measles death to its dashboard on Wednesday, but the agency would not reveal whether the death occurred in Pennsylvania or another state – which is “notable” as the agency delays reporting other measles deaths, experts say.
The CDC cited privacy laws in not sharing the name of the state, but experts say there are no privacy concerns in doing so – and this information is important for the public to have as the outbreak continues accelerating, growing by 8% in one week to 4,410 confirmed cases so far this year, nearly double last year’s count.

New U.S.-Israeli Plans to Attack Iran, and Trump’s Whistle-Blower Rewards Program
Is Trump going to steal the midterms? - Stateside with Kai and Carter
This week, the Department of Justice charged 28 green card holders in California over alleged voter fraud. It’s the latest move by the Trump administration to crack down on noncitizen voters, and part of a wider push to throw the results of the midterms into doubt. In today's episode, Carter Sherman and Kai Wright are joined by George Chidi and Sam Levine, two reporters who have spent years covering Donald Trump’s attacks on voting rights. They analyze the tactics being used to purge voter rolls, and look ahead to how Trump might react if the results on election day don’t go his way.

The U.S. and Israel are reportedly developing plans for major strikes on Iran after the U.S. midterm elections in November.
Citing people familiar with the deliberations, the New York Times reported on Wednesday that Defense Secretary Pete Hegseth discussed the possibility of renewed strikes on Iran with Israeli Prime Minister Benjamin Netanyahu in Israel this week. Possible targets of the strikes reportedly include Iran’s energy infrastructure, nuclear facilities, and missile and drone arsenal. TIME has reached out to the White House for comment.
U.S. officials have repeatedly asserted that the Iranian Islamic Revolutionary Guard Corps are teetering on the edge of collapse but are deliberately prolonging the war in an effort to meddle with Republican prospects in the midterm elections. Once the elections are over, President Donald Trump promised last month, the Iranian regime would quickly capitulate.
“I think the war is going to end immediately after the election,” Trump said. “They can’t hold out any longer.”
Renewed strikes could complicate that outlook.
Some officials have reportedly argued that resuming attacks for an intense but limited campaign would hasten Iran’s economic collapse, especially as the country has been squeezed by an ongoing U.S. blockade on Iranian ports and economic sanctions campaign. The officials hope the blow will make Iran more amenable to negotiations.
Trump has at times shared that view.
Last week, Trump told Newsmax he was considering additional military action in Iran, including a possible strike on Iran’s Pickaxe Mountain, a nuclear facility deep underground. His comments came amid reports that he was weighing deploying a 22,000 GBU-43/B Massive Ordnance Air Blast bomb, also known as the “mother of all bombs.”
The President added the war would end soon, be it through negotiation or escalation.
“Do I annihilate the Islamic Republic and do it quickly, never giving them a chance to kill and destroy people and countries again? Do I drive them into hell with no chance of survival and no hope of future greatness or generations?” he said in a speech to the United Nations General Assembly last month.
“But I believe we’ll make a deal,” he added, “right after the election.”
Will the U.S. renew strikes on Iran?
Intensified fighting between the Iran-aligned Houthi rebels and the Saudi and Yemeni governments has threatened to create a broader regional crisis that could be harder to disengage from. The State Department on Wednesday ordered nonemergency government employees and their families to leave Saudi Arabia amid escalating attacks by the Houthis on Saudi infrastructure.
Houthi attacks on Saudi airports and Aramco facilities, as well as their attempts to disrupt shipping through Bab El-Mandeb, which has become an important alternative to the Strait of Hormuz for energy trade, could prompt direct U.S. strikes in support of Saudi Arabia, analysts have said. Trump said earlier this month that the U.S. “may” join Saudi strikes on the Houthis, although that has yet to transpire.
Israel’s Oct. 27 election could also raise the stakes of additional military action. Netanyahu, whom Trump has endorsed, would remain in office until a new government is formed, even if his bloc loses the election, and his government would retain the authority to order strikes during that transition. But renewed strikes before the election, or after an electoral defeat, could invite scrutiny. “One ordered in the last weeks of a deadlocked campaign would be judged in Israel as politics as well as strategy,” Gregg Roman, executive director of the Middle East Forum, wrote in a September analysis.
Nevertheless, the forum assessed that a large-scale Israeli strike on Iranian territory, with or without U.S. participation, was probable before the end of the year. Analysts told the Times Netanyahu could use the prospect of joint strikes to form a unity government that could allow him to stay in power.
“The larger constraint,” Roman argued, “is Washington.”
Trump has not yet approved the proposed strikes, the Times reported.
Trump has also called off plans to renew attacks on Iran before. He reportedly blocked an Israeli plan for a multi-day offensive against Iran earlier this month, and rejected five proposals for major operations against Iran or the Houthis in recent months.
The U.S. and Iran have not exchanged major fighting in recent weeks. The last reported U.S. strikes on Iran were on Sept. 8, even as Iranian attacks on commercial shipping have continued. Earlier this month, Trump ruled out attacking Iran before the midterms.

How might Iran respond to new strikes?
Tehran’s reluctance to make concessions to the U.S. appears to have strengthened, rather than weakened, over the course of the war. Iranian leaders reiterated this week that they will not directly negotiate with the U.S. unless Washington accedes to certain demands, which include ending its naval blockade and releasing frozen Iranian funds.
The initial U.S. and Israeli bombing campaign on Iran that began the war on Feb. 28, as well as June 2025 attacks during an earlier round of U.S.-Iran nuclear diplomacy, also hardened the Iranian view that the U.S. is not serious about negotiating. Iranian Foreign Minister Abbas Araghchi said in March that the previous disruptions of negotiating rounds had increased distrust in Washington.
Last month, the IRGC published an open letter appealing to American voters to “wrest control” from their government. In the letter, the IRGC said: “Despite all the hardships that our enemies impose on us, we will continue fighting, as we have done for the past 47 years.”
Both the U.S. and Iran appear to believe they hold enough leverage to achieve their goals, and those “dueling perceptions” have impeded progress towards a deal, according to an Oct. 1 analysis by the New York-based nonpartisan research organization The Soufan Center.
Iran’s key point of leverage is its blockade of the Strait of Hormuz, a narrow waterway vital to global energy trade. Iran’s militarization of the strait has disrupted global oil and liquefied natural gas supplies, leading to soaring energy prices and inflation.
Analysts previously told TIME that the higher prices are politically costly for Trump. In recent weeks, a growing number of Republicans have broken with Trump on Iran. The President has also seen his lowest approval ratings of his second term.
Iran’s ability to choke off regional oil exports, however, appears to be waning. Middle East oil exports topped prewar levels last week as shipping companies use alternative routes to bypass the Strait of Hormuz. HSBC Group Chief Executive Georges Elhedery also projected that Hormuz could be “redundant” in five years thanks to investment in alternative logistics routes.
Iranian officials told the Times that they are aware of the U.S. and Israel’s war planning and are developing their own tactics.
Earlier this week, IRGC spokesperson Hossein Mohebbi told the Tehran Times that “even a limited” attack from Washington would provoke a “serious energy crisis” for the world. Iranian Foreign Ministry spokesperson Esmail Baghaei said that an attack on Pickaxe Mountain would be met with a response “just as hard,” if not “stronger.”
And earlier this month, Iranian officials said Iran had prepared potential retaliatory operations that would depart from the U.S. and Israel’s assumptions. Security Chief Mohsen Rezaei told Press TV that Iran could respond to renewed attacks by targeting new targets, including U.S.-linked data centers and AI facilities in the Gulf, as well as subsea communications cables. Last month, Iran threatened to retaliate against any further U.S. attacks by targeting U.S. oil and gas assets in the Gulf.
In a post on Telegram on Sunday, Mahdi Mohammadi, a senior adviser to Iran’s negotiator Gen. Mohammad Bagher Ghalibaf, said, if the U.S. and Israel attack, “they may want to keep it short, but we will not allow it.”
He added on Wednesday: “The war will continue longer and across a wider geography than the enemy calculates.”
