Ukrainian President Volodymyr Zelensky is set to visit Prime Minister Sir Keir Starmer in the UK on Tuesday to agree a new defence partnership aimed at tackling cheap attack drones. Downing Street said the deal would bring together Ukrainian expertise and the UK's industrial base to manufacture and supply drones and other capabilities. The two leaders are also expected to discuss further support Ukraine against Russia's full-scale invasion, now in its fourth year. Their meeting comes as the US-Israeli war with Iran enters a third week, during which US President Donald Trump has criticised the UK and other countries over the extent of their response to the conflict. Under the partnership between the UK and Ukraine, closer co-operation in the defence industries will also be sought with third countries as part of efforts to bolster international security.

US's new scramble for Africa is biomedical imperialism Late in February, Zimbabwe pulled out of a proposed $367m United States health funding agreement after objecting to provisions requiring broad American access to sensitive health data. The five-year programme was presented as support for HIV/AIDS, tuberculosis, malaria and epidemic preparedness efforts. However, the terms demanded extensive sharing of national health intelligence, including epidemiological surveillance data and pathogen samples, while offering no binding guarantees that Zimbabwe would receive equitable access to medical technologies developed from them. Harare called the proposal an "unequal exchange", warning that Zimbabwe risked supplying the "raw materials for scientific discovery" while the resulting benefits could remain concentrated in the United States and global pharmaceutical firms. Critics increasingly describe this pattern as biomedical extractivism: a toxic combination of exploitative research practices and colonial thinking that reinforces Western dominance.

They will start showing up as an option in the Uber app. Uber's and Motional's Hyundai Ioniq 5 autonomous EVs will start appearing as an option for riders in Las Vegas. Passengers requesting for an UberX, Uber Electric, Uber Comfort or Uber Comfort Electric ride may be matched with a Motional robotaxi. They will not be forced to take it, though, and will be notified and given the option to decline and choose a regular ride instead. But if they want to try it, they can boost their chances of getting matched with a robotaxi ride by opting in via the Ride Preferences section under Settings.

As AI drives extraordinary power demands, energy intelligence is rapidly becoming a core business metric. Loudoun County, Virginia, once known for its pastoral scenery and proximity to Washington, DC, has earned a more modern reputation in recent years: The area has the highest concentration of data centers on the planet. Ten years ago, these facilities powered email and e-commerce. Today, thanks to the meteoric rise in demand for AI-infused everything, local utility Dominion Energy is working hard to keep pace with surging power demands. The pressure is so acute that Dulles International Airport is constructing the largest airport solar installation in the country, a highly visible bid to bolster the region's power mix. Data center campuses like Loudoun's are cropping up across the country to accommodate an insatiable appetite for AI.

Outside OpenAI's headquarters, a handful of people gathered on Monday holding pieces of colorful chalk. They got down on their knees and started writing messages on the sidewalk. Please no legal mass surveillance. At issue was a business deal that the company recently signed with the Department of Defense, following the Pentagon's sudden turn against Anthropic . OpenAI will now supply its technology to the military for use in classified settings, the sorts that may involve wartime decisions and intelligence-gathering--an agreement, many legal experts told me, that could give the government wide-ranging powers.

The AI search startup once predicted advertising would be a massive business. Perplexity is abandoning plans to put ads in its AI search product as the industry looks for sustainable business models that won't hurt user trust. The changes are part of a larger strategic shift for the company, which has long focused on disrupting Google Search's business. Google is changing to be like Perplexity more than Perplexity is trying to take on Google, said a Perplexity executive at a press briefing on Tuesday. Executives spoke to the press on the condition of anonymity.

Sales of the iPhone hit an all-time high in the final three months of last year, tech firm Apple reported on Thursday. Revenue rose by 16% compared to the same period last year to $144bn (£82.5bn) - the strongest growth since 2021 - thanks to a jump in sales in China, as well as Europe, the Americas, and Japan. However, sales in other parts of the company were less positive. Wearables and accessories, which include things like the Apple Watch and AirPods, fell by roughly 3%. Apple chief executive Tim Cook said the iPhone's boost in sales meant the firm was in supply chase mode.

Google's Smart Glasses Will Have the Best Software. But They'll Have to Win on Style Too When Google releases its smart glasses in the coming months, the strength of its AI-powered software will be its biggest leg up on its rivals. But will people want to be seen wearing them? When Google ships its newly refreshed smart glasses this year--as the rumor mill is predicting, and as the hands-on demos posted just last week have all but confirmed it will--the company's tech will be joining a crowded field. But whether this rebirth of Glass will pop or fizzle comes down to whether Google can best its main competitor: Meta .

Apple's Google artificial intelligence partnership will launch a Siri overhaul using Gemini's large language models, the tech giants announced.

No one can truly have it. The world is too interconnected for nations to go it alone. Governments plan to pour $1.3 trillion into AI infrastructure by 2030 to invest in "sovereign AI," with the premise being that countries should be in control of their own AI capabilities. The funds include financing for domestic data centers, locally trained models, independent supply chains, and national talent pipelines. This is a response to real shocks: covid-era supply chain breakdowns, rising geopolitical tensions, and the war in Ukraine. But the pursuit of absolute autonomy is running into reality.
