This week, with air raid warnings wailing in the distance, Kyiv held a funeral for two sisters. They had already lost their father who had been fighting on the front line. Their grieving mother is now the family's sole survivor. This is the human cost of the largest sustained Russian aerial assault so far - with 1,500 drones and 56 missiles fired at Ukraine within 48 hours. But the loss of life could have been even higher.

Elon Musk's SpaceX has revealed its plans to go public in the US, allowing people to trade shares in the firm on the stock market. SpaceX makes rockets, offers a satellite internet service called Starlink, and also owns Musk's controversial artificial intelligence (AI) firm xAI. The initial public offering (IPO) on the US stock market is set to be the largest in Wall Street history and could start next month under the ticker symbol SPCX. Because of the shares he will own in SpaceX, the IPO could make billionaire Musk, who is already the world's richest person, a trillionaire. SpaceX values itself at $1.25tn, and Musk's majority ownership of the company means his share could be worth more than $600bn.

Israeli air strikes have killed at least 19 people in southern Lebanon, the country's health ministry has said. Ten of them, including three children and three women, were killed in a single attack that hit a house in the town of Deir Qanoun, the ministry said. Lebanon was drawn into the war on 2 March, when the Iran-backed armed Shia Islamist group Hezbollah fired rockets at Israel in retaliation for US-Israeli strikes that killed Iran's supreme leader. The latest deaths less than a week after the US said that Lebanon and Israel had agreed to extend a ceasefire by 45 days, with the two sides set to resume talks at the beginning of June. Despite the extension, both Israel and Hezbollah have continued to exchange fire, especially in southern Lebanon.

Estonia has said a Nato fighter jet shot down a drone, which it suspects was a Ukrainian projectile knocked off course by Russian electronic jamming, over its territory. Defence Minister Hanno Pevkur said a Romanian F-16 fired a missile and drone debris fell in a marshy area in central Estonia on Tuesday. Ukraine reacted by accusing Russia of deliberately redirecting Ukrainian drones launched at legitimate military targets in Russia, apologising to Estonia and all of our Baltic friends for such unintended incidents. Russia has not commented on the latest in a series of recent drone incursions over Nato members Estonia, Latvia and Lithuania. Last week, Latvian Prime Minister Evika Silina resigned following a political crisis over Russia-bound Ukrainian drones straying into Latvian territory.

It is not only OpenAI but the AI race itself that was vindicated in the California courtroom last night . Even though Elon Musk essentially lost on a technicality, there's a clear signal from the verdict that making lots of money from AI and competing fiercely with rivals is simply business. The industry sometimes tries to display a united front, especially when it comes to safety, research and inclusivity. But this case served as a powerful reminder that none of the AI giants are charities and don't have to be, even if they once said otherwise. Cracks in the façade of industry collaboration for the sake of humanity have been exposed before.

Banking giant Standard Chartered has become the latest major company to announce job cuts as it increases its adoption of artificial intelligence (AI). The firm, which has its headquarters in the UK, said it will cut more than 15%, or around 7,800, back-office roles by 2030. The BBC understands that Standard Chartered aims to move some of the effected workers to other roles in the business. Companies around the world have announced major job cuts in recent months as they increasingly use AI tools for roles currently carried out by humans. The company did not give details of where the roles would be cut.

Researchers at the University of Cambridge are using satellite data and AI in an effort to slow the decline in Britain's hedgehog population. Using an AI tool called Tessera, which analyses detailed images of the UK gathered from space, experts can precisely determine locations of hedgehog habitats - and where these are disappearing. The resulting maps capture landscapes in minute detail, including down to individual hedgerows, while AI can accurately predict hedgehog-friendly places obscured by cloud cover. Those behind the project hope it will help to shed light not just on where hedgehogs live across the UK, but barriers preventing them from finding food and mates. The researchers say Tessera's outputs can be used to track the impact of new housing developments and other environmental changes on landscapes that could affect hedgehogs over time.

Elon Musk just lost another lawsuit. Elon Musk, the world's richest man, has not been winning in court lately. His loss on Monday in his lawsuit against OpenAI and its co-founder Sam Altman is the latest in a string of legal defeats or settlements. Late last year he agreed to settle with former Twitter executives and thousands of former employees of the social platform, which he has renamed X, after fighting for years to pay them nothing. Then in March, he lost a case brought against him by investors of Twitter, who claimed they were misled by public statements he made during the takeover.

A California jury has tossed out Elon Musk's high-profile lawsuit against OpenAI and its boss Sam Altman. In a unanimous verdict, the case was thrown out because Musk had filed his lawsuit after a statute of limitations to bring such claims had expired. Musk had accused Altman of breaching a non-profit contract by shifting the ChatGPT-maker to a for-profit company after Musk donated $38m (£28.5m). Musk had argued Altman deceived him by accepting his money and then reneging on OpenAI's original non-profit mission to develop artificial intelligence (AI) technology for the benefit of humanity. Jurors spent three weeks viewing internal correspondence and hearing testimony, and arrived at a verdict on Monday after deliberating for roughly two hours.
