A dismal jobs report affirms earlier warnings about the economic impact of Donald Trump's tariffs, immigration restrictions, and -led firings. At the start of last week, I watched a big cargo ship stacked high with containers enter New York Harbor. As the vessel approached the Verrazzano-Narrows Bridge, it appeared to stop, but that was an illusion created by its size and the slowness of its advance. Fifteen minutes later, it had managed to push its way under the bridge. Throughout the years, I've often compared the U.S. economy to a giant freighter that is tough to deflect from its course, and, since Donald Trump was elected for a second time, this metaphor has become particularly apt.

Ukraine has reported dozens of civilian deaths from Russian attacks over the past week, including three killed in a late-night assault on Wednesday in the southeastern city of Dnipro. A child was among the victims of the drone attack, which came hours before high-stakes meetings in Paris due to take place later on Thursday, during which United States Secretary of State Marco Rubio and special envoy to the Middle East Steve Witkoff are to meet French President Emmanuel Macron and other European officials to discuss the conflict. Ukraine's defence and foreign ministers, as well as President Volodymyr Zelenskyy's chief of staff, are also in the French capital for talks with US and European Union delegations, though Kyiv's delegation has not specified who it plans to meet. But as Moscow's self-imposed 30-day ceasefire on energy infrastructure approached its close, talks to achieve a broader ceasefire so far have showed little sign of progress. Russia has stuck to its hardline positions while accusing Ukraine of violating the energy ceasefire, to which Kyiv never agreed.

President Trump's press secretary Karoline Leavitt touted him as "the most transparent and accessible president in American history," particularly compared to former President Biden. President Trump said on Friday that the first physical examination of his second term went well, and overall he feels he's in "very good shape." The president told reporters on board Air Force One while en route to his home in West Palm Beach Friday evening that the yearly presidential physical at Walter Reed Medical Center showed he has a "good heart, a good soul," and "overall, I think I'm in very – I felt I was in very good shape." He also took a cognitive test. "I don't know what to tell you other than I got every answer right," the president told reporters.

One person was killed Sunday as Russian air strikes hit the Ukrainian capital, Kyiv, while the death toll from Friday's deadly attack on the central Ukrainian city of Kryvyi Rih continued to rise. The Kyiv victim was found close to the strike's epicenter of the attack in the city's Darnytskyi district, Mayor Vitali Klitschko said. A further three people were injured in the strike, which saw fires break out in several nonresidential areas, damaging cars and buildings. In a statement on social media, Ukrainian President Volodymyr Zelenskyy said the intensifying Russian attacks showed that there is still insufficient international pressure on Moscow. US WILL KNOW IN'MATTER OF WEEKS' IF RUSSIA IS SERIOUS ABOUT PEACE OR USING'DELAY TACTIC': RUBIO He said Russia has launched more than 1,460 guided aerial bombs, nearly 670 attack drones and more than 30 missiles at Ukraine in the past week alone.

A pro-Palestinian protest by Microsoft employees has interrupted the company's 50th anniversary celebration, the latest backlash over the tech industry's work to supply artificial intelligence technology to the Israeli military. The protest began on Friday as Microsoft AI CEO Mustafa Suleyman was presenting product updates and a long-term vision for the company's AI assistant product, Copilot, to an audience that included Microsoft co-founder Bill Gates and former CEO Steve Ballmer. "Mustafa, shame on you," shouted Microsoft employee Ibtihal Aboussad as she walked towards the stage and Suleyman paused his speech. "You claim that you care about using AI for good but Microsoft sells AI weapons to the Israeli military. Fifty-thousand people have died and Microsoft powers this genocide in our region."

At least 14 people, including six children, have been killed in a Russian missile attack on a residential area of the central Ukrainian city of Kryvyi Rih, according to President Volodymyr Zelenskyy, making it one of Moscow's deadliest strikes this year. Friday's attack on Zelenskyy's hometown, which comes as United States President Donald Trump is pushing for a ceasefire in the war, damaged residential blocks and caused fires, Dnipropetrovsk Governor Serhiy Lysak wrote on the Telegram messaging app. The dead and wounded could be seen lying on the pavement, one of them by a playground, in unverified videos circulating on Telegram as grey smoke rose into the sky. At least 50 people were wounded, the emergency services said, adding that the figure was growing. More than 30 people, including a three-month-old baby, were admitted to hospital, Lysak said.

Tesla Chief Executive Elon Musk told employees to hold on to their stock and stay optimistic amid a series of blows to his company's reputation that have sent shares plunging. Since Musk began his prominent role in the Trump administration in January, Tesla stock has taken a hit as protests against the electric vehicle brand have erupted across the country. Tesla shares rose 5% Friday to close at 248.71 but have dropped 34% this year. With Chief Executive Elon Musk playing a prominent role in the Trump administration, many Tesla drivers are no longer happy about supporting the car brand. Tesla vehicles, dealerships and charging stations have become targets for vandalism as distaste grows for Musk and his Department of Government Efficiency, or DOGE.

DOGE leader Elon Musk opens up about his work in space on'Kudlow.' Elon Musk has confirmed that SpaceX's Starship will head to Mars at the end of 2026. The ship will be carrying Optimus, Tesla's humanoid robot. The tech billionaire said that if all goes well, humans could be on the red planet by 2029, although he admitted that 2031 is more likely. NASA's Perseverance Mars rover used its dual-camera Mastcam-Z imager to capture this image of "Santa Cruz," a hill within Jezero Crater, on April 29, 2021, the 68th Martian day, or sol, of the mission. The X account for Optimus replied to Musk's announcement with just two words: "Hold on."

We look at reasoning on GSM8k, a dataset of short texts presenting primary school, math problems. We find, with Mirzadeh et al. (2024), that current LLM progress on the data set may not be explained by better reasoning but by exposure to a broader pretraining data distribution. We then introduce a novel information source for helping models with less data or inferior training reason better: discourse structure. We show that discourse structure improves performance for models like Llama2 13b by up to 160%. Even for models that have most likely memorized the data set, adding discourse structural information to the model still improves predictions and dramatically improves large model performance on out of distribution examples.

OpenAI on Friday rejected a 97.4bn bid from a consortium led by billionaire Elon Musk for the ChatGPT maker, saying the startup is not for sale. The unsolicited approach is Musk's latest attempt to block the startup he co-founded with CEO Sam Altman – but later left – from becoming a for-profit firm, as it looks to secure more capital and stay ahead in the AI race. "OpenAI is not for sale, and the board has unanimously rejected Mr Musk's latest attempt to disrupt his competition. Any potential reorganization of OpenAI will strengthen our nonprofit and its mission to ensure AGI benefits all of humanity," OpenAI said on X, quoting its chair Bret Taylor, on behalf of its board. On Tuesday, Altman told news website Axios that OpenAI was not for sale.
