In the final weeks before Romania’s presidential vote in November 2024, TikTok accounts that had previously spent years posting about manicures or fashion suddenly started promoting a little-known politician named Calin Georgescu.

His posts, espousing hard-line views on immigration and anti-Semitic tropes, were viewed 120 million times before the vote. Georgescu, who had previously been polling in the single digits, stunned observers by winning the election’s first round with 23 percent of the vote.

In the Netherlands, Adriana Iamnitchi was watching closely. As chair of computational social sciences at Maastricht University, she leads the research into disinformation campaigns. She wanted to know how pro-Georgescu content was being monetized on TikTok through hidden influencer marketing and livestreamed political content.

Paramount Skydance agreed to a longer-term delay of its $111 billion acquisition of Warner Bros. Discovery, preventing the companies from combining until after a judge rules on the merits of a case in which a dozen states challenged the legality of the merger.

Under a stipulation filed in court today, the states and companies agreed that the merger will not be completed and the firms will not integrate their operations until "five days after the merits determination in these matters," or on June 1, 2027, whichever is earlier. The delay was also agreed to by the Writers Guild of America, which filed its own lawsuit to block the merger. If there is no merits determination by June 1, the plaintiffs could seek a preliminary injunction to keep blocking the deal.

The agreement amounts to "a months-long halt" to the merger, New York Attorney General Letitia James' office said. “Halting this merger while our case proceeds is a critical victory in our efforts to uphold the law and protect the film and television industries," James said.

In a widely expected move, a committee organized by the Food and Drug Administration (FDA) has voted to endorse removing restrictions on the manufacture of peptides for human use. Thursday's panel meeting saw a sharply divided group recommend lifting limits on four peptides; votes on three additional peptides are scheduled for today. The move comes despite a continuing lack of evidence regarding their safety and effectiveness.

The move had been telegraphed months earlier as peptide enthusiast and Health and Human Services Secretary Robert F. Kennedy Jr. took steps to ensure this outcome.

Like proteins, peptides are composed of amino acids that are chemically linked into a chain. Peptides differ merely by length; they're often 10–20 amino acids long, in contrast to proteins, which can be hundreds or thousands. Some of them, such as insulin, are specifically made by targeted processing of a protein into shorter fragments, and the resulting peptide interacts with receptors that have evolved to send signals to cells based on its levels.

After criticism from a federal judge, the Department of Justice yesterday withdrew demands for phone records and grand jury testimony from New York Times reporters who wrote about security concerns related to the Air Force One jet donated to Trump by Qatar.

It was a setback in the Trump administration's attempts to unmask journalists' confidential sources. US District Judge Arun Subramanian "grilled Justice Department lawyers for nearly an hour over their handling of the subpoenas" during a hearing on Thursday, The New York Times wrote.

“Either we can quash the subpoenas, or you could withdraw the subpoenas,” Subramanian reportedly told Sean Buckley, chief counsel for the US attorney in New York's southern district.

A U.S. citizen has asked a court to throw out the government's claim that he gave over a passcode to border authorities that wiped his phone's data, opening up fresh questions about a person's constitutional rights at the U.S. border.

The offline messaging app surged in popularity in India amid protests in New Delhi.

AI companies, including Nvidia and Mistral, urge policymakers to avoid broad restrictions on open-weight AI models as Washington debates responses to Chinese AI and alleged model distillation.

The Trump administration is quietly considering a rule change that could make it easier for polluters to build facilities—including certain gas plants and diesel generators that power data centers—with little to no notice to the public.

On Wednesday, the Environmental Protection Agency held a public hearing on a proposed rule change that would hand the power to states to decide how the public participates in the permitting process for certain new sources of air pollution. The proposed rollback comes as data centers face greater pushbackacross the US, with many communities using the permitting process to try to slow down development. Any changes could have major consequences for how ordinary people are given notice about new or expanded polluting facilities coming into their neighborhoods.

“As someone actively working in communities with data centers, I know this to be fundamentally true: People want to have a say,” Vanessa Lynch, a Pennsylvania organizer with Moms Clean Air Force, said at the EPA hearing.

EU law gives researchers unprecedented rights to scrutinize social media data. Researchers say TikTok, X, and Meta impede their attempts to look inside.

A proposed law called the AI Kill Switch Act would let US government officials order the shutdown of AI systems "that can cause catastrophic harm," the bill's sponsors said today.

If approved by Congress, the bill would let the Trump administration and future administrations decide when an AI company must block user access, disable or restrict a particular capability, or shut an entire AI system down completely. The bill would require AI makers to deploy technical capabilities allowing them to throttle or shut down the systems when ordered to do so by the government.

The bill would amend the Homeland Security Act of 2002 with authority for the Secretary of the Department of Homeland Security to order the suspension or shutdown of AI systems. AI developers that refuse to shut systems down could face fines of up $20 million for each day on which a violation occurs.

On Tuesday, the White House Office of Science and Technology Policy (OSTP) released a report entitled "Science: A New Golden Age," in which it lays out how it has viewed science, found it lacking, and believes the Trump administration is in the perfect position to fix things. It's a bit unexpected coming from an administration that has been proposing crippling funding cuts to research and trying to enable political appointees to terminate grants awarded based on scientific merit.

The report presents itself as the spiritual successor of "Science, the Endless Frontier," a policy document that laid out the case for government-funded science in the wake of World War II. The New Golden Age (SNGA) says that, while the concepts promoted by the original remain vital, the circumstances have changed such that we need major revisions to how the government is implementing things.

The result is an odd mix. It completely ignores or glosses over many things that the administration is doing to harm scientific progress. In some cases, it identifies issues that have already been discussed as problems within the scientific community, but misrepresents them. Elsewhere, it's a mixture of political grievances, ideas without a solid intellectual foundation, and an injection of Silicon Valley's perspective on innovation (Michael Kratsios, the director of the OSTP, formerly worked with Peter Thiel). As a result, it's unlikely to have anything like the impact of "Science, the Endless Frontier."

As access to Anthropic’s and OpenAI’s frontier models becomes more restricted, Chinese labs are pitching their open-source alternatives as stable, accessible, and increasingly capable.

Laos did something no other country has tried: it banned the import of new gas and diesel passenger cars outright. As of June 1, nearly every new car cleared for import has to be electric.

It’s the most aggressive EV mandate on the planet right now, and it has almost nothing to do with consumer demand.

Diplomats say de-escalation talks continue as Trump vows retaliation over US soldier deaths

The US military said it has launched its 10th consecutive round of strikes on Iran to force the reopening of the strait of Hormuz.

Earlier on Monday, Iran’s president said the country is in a “full-scale war” after the US expanded its aerial campaign and Tehran struck Washington’s Gulf allies, even as diplomats said talks to de-escalate were continuing.

Heatwaves, high energy prices, calls for reindustrialisation and North Sea drilling are all high on the to-do list

Wildfires cast a pall of smoke this week over Greater Manchester, whose former mayor Andy Burnham stands on the threshold of No 10. Amid three UK heatwaves so far this year, which have killed thousands of people in England and Wales, damaged harvests and left children crying in classrooms, the new prime minister’s plans for the climate crisis remain as shrouded as his city.

“Burnham has been very quiet about the climate [crisis] so far,” says Chris Venables, an environmental campaigner and fellow at the Green Alliance thinktank. “I don’t think [it] is at the forefront of his mind, but that does not mean he will water down this agenda.”
