Breaking AI & Tech News Analyzed

Anthropic, a leading artificial intelligence company, is set to face off against the US Pentagon in a San Francisco court over a ban that prevents the military from using its Claude AI model. The company refused to remove safety guardrails that prevent its AI from being used for fully autonomous weapons and mass domestic surveillance.The legal showdown began on Tuesday, with US District Judge Rita Lin presiding over the hearing. Anthropic argues that the Pentagon's move is an unprecedented and unlawful designation that violates freedom of speech protections and due process rights.The Pentagon-led ban was enacted after Anthropic refused to strip safety guardrails from its AI model. The company's designation as a national security supply chain risk prohibits anyone within the Defense Department or its contractors from using the technology.Legal experts believe that Anthropic is likely to prevail, pointing to a February 27 post on X in which Defense Secretary Pete Hegseth said he is directing the DoD to designate Anthropic a Supply-Chain Risk to National Security. The post also said that contractors, suppliers, or partners for the United States military are prohibited from commercial activity with Anthropic.The White House has pushed back on Anthropic's claims that government action violated free speech protections under the First Amendment of the US Constitution, saying the dispute stems from contract negotiations and national security concerns rather than retaliation.Democratic Senator Elizabeth Warren of Massachusetts has penned a letter to Hegseth voicing her concerns, saying she is particularly concerned that the DoD is trying to strong-arm American companies into providing the Department with the tools to spy on American citizens and deploy fully autonomous weapons without adequate safeguards.

The traditional cold war diplomacy of brinkmanship, characterized by carefully balanced standoffs and rules-based international order, has given way to a world in freefall. This shift is exemplified by the ever-widening conflict in the Gulf where strategic objectives remain as unclear as the potential endpoint of hostilities.Approaching a month since the United States and Israel launched attacks on Iran, the stated objectives of removing the country's nuclear threat and destroying its ballistic missile capability appear increasingly disconnected from the disproportionate impact on civilians and neighboring Gulf nations. Despite these consequences, the Iranian regime's willingness to escalate the conflict shows no signs of diminishing.The Guardian Weekly's coverage examines this critical juncture through multiple perspectives. Patrick Wintour recounts the pivotal week when global tensions reached a tipping point, while Richard Partington analyzes the long-term economic implications of a prolonged conflict, from oil price fluctuations to inflationary pressures and economic growth impacts. From South Lebanon, William Christou reports on healthcare professionals caught in the crossfire of Israeli airstrikes, highlighting the human cost of the escalating violence.Emma Graham-Harrison provides insight from Jerusalem, examining Israeli Prime Minister Benjamin Netanyahu's strategy of attempting to rehabilitate his image through what he frames as destruction of an 'axis of evil.' Meanwhile, Simon Tisdall poses a critical question: when US President Donald Trump eventually seeks to halt the conflict, will any parties be willing to heed his calls for de-escalation?Beyond the primary geopolitical focus, this week's Guardian Weekly edition explores several significant developments across different sectors. The UK political landscape features an examination of the upcoming local elections, where voter sentiment appears increasingly focused on rejecting established parties rather than actively supporting alternatives. The scientific section explores innovative approaches to addressing snoring disorders through CPAP machines, while the culture section features an in-depth interview with Dave Grohl discussing Foo Fighters, personal challenges, and grief following the loss of bandmate Taylor Hawkins.In sports, the publication celebrates the remarkable achievement of British athletes Keely Hodgkinson, Georgia Hunter Bell, and Molly Caudery, who each secured gold medals at the world indoor athletics championships in Poland, showcasing British excellence in track and field events.

Double world darts champion Luke Littler recently visited the England squad at their St George's Park training base, where he hosted a special darts tournament for the players as they prepare for upcoming pre-World Cup friendlies against Uruguay and Japan.The 19-year-old darts star shared dinner with the footballers before organizing the "Three Lions darts championship" at their Burton base on Tuesday night. In a surprising turn of events, Newcastle goalkeeper Aaron Ramsdale claimed the title of camp champion, leaving Littler thoroughly impressed despite Phil Foden hitting a notable 180 in the final."It was a dream as a football fan to come here to see the facilities, meet all the players and sit down and have dinner and have a laugh with them," said Littler, who is set to travel to Berlin for the latest round of Premier League darts action. "We played a bit of darts – as they were warming up, Thomas Tuchel told me to teach these boys a lesson! There's some good potential there in Phil Foden and Aaron Ramsdale. James Trafford had a little bit as well. The others not so much!"During his visit, Littler was presented with a signed shirt from the England squad, with Jude Bellingham adding a personal touch by giving him a signed jersey featuring the encouraging message "keep smashing it" on the back. The darts champion wished the England squad luck for their upcoming international campaign, expressing hope that they could "bring it home" this summer.

A newly expanded policy from the Trump administration could require travelers from five World Cup-qualified African countries to post a bond of up to $15,000 in order to enter the United States for the tournament.Visa bonds function as security deposits: a one-time payment that is meant to be refunded after a traveler exits the US under the terms of their visa. The amounts typically range between $5,000 and $15,000, and are required for passport holders from certain countries to enter the US legally under B-1 or B-2 visas, which are necessary for business travelers or tourists.The US State Department has mandated these bonds since launching a pilot program in late 2025, targeting many of the same countries affected by the Trump travel ban along with others – predominantly nations from Africa, the Middle East, Latin America and parts of Asia. Last week, the state department announced an expansion of the program, with visitors from 50 countries now required to submit the deposits if requested by US consular officials.Among those 50 countries, five have qualified for the World Cup, all from Africa: Algeria, Cape Verde, Côte d'Ivoire, Senegal and Tunisia. Though refundable, the cost of the bonds alone is sufficient to make travel to the US prohibitively expensive for most fans from these nations, where average annual income levels are approximately $5,000 per year or less. Tunisia is scheduled to play one group-stage game in the US with the other two in Mexico. Senegal and Côte d'Ivoire will play twice in the US and once in Canada. Algeria and Cape Verde will compete in all three of their group-stage matches in Mexico.Even if affordable for some supporters, the multi-thousand dollar requirement adds another significant complication for fans from these countries, including exorbitant ticket prices for the games themselves, hotel rates far above average, plus additional visa processing delays and potential safety concerns created by the presence of federal immigration officers from ICE and other agencies in US cities.It remains unclear which entities, if any, will be exempt from the visa bonds. While Trump's travel bans contain exemptions for athletes and officials participating in major sporting events like the World Cup, the visa bonds program contains no such provision.The 2026 World Cup is scheduled to commence on June 11, with the final taking place on July 19 at MetLife Stadium in East Rutherford, New Jersey.

Three elite runners, Jessica McClain, Emma Grace Hurley, and Ednah Kurgat, who were leading the USA Track & Field Half Marathon Championships in Atlanta earlier this month, were inadvertently led off course by a guide vehicle. This chaotic turn of events resulted in them finishing in ninth, 12th, and 13th place, respectively, more than two minutes behind the winner, Molly Born.The incident deprived them of the top prize of $20,000 and the three qualifying places for the World Road Running Championships. However, USATF announced on Wednesday that World Athletics had granted permission to expand its team from four to seven, allowing McClain, Hurley, and Kurgat to compete in Copenhagen this September.“From the moment this happened, our focus was on doing right by the athletes,” said USATF CEO Max Siegel. “Jessica, Emma Grace, and Ednah had clearly separated themselves in the race and we are sorry they did not get to celebrate their accomplishment by breaking the tape.”The USATF team for the championships will include Born, Carrie Ellwood, and Annie Rodenfels, along with a final athlete determined by the world rankings in May. The team will consist of four “scoring athletes” and three “non-scoring athletes,” with USATF funding prize money for the non-scoring athletes.

A recent study published in the European Journal of Preventive Cardiology has revealed that small changes to daily habits can have a significant impact on cardiovascular health. The research, conducted by experts from Australia, Chile, and Brazil, examined data on more than 53,000 middle-aged UK adults taking part in the Biobank study.The study found that sleeping for 11 minutes more each night, doing 4.5 additional minutes of brisk walking, and eating an extra 50g of vegetables each day can reduce the risk of major cardiovascular events, including heart attacks and strokes, by about 10%. These small behavior changes were found to be more "achievable and sustainable" compared to attempting major changes in a single behavior.According to the study, the "optimal" way to avoid cardiovascular incidents includes getting eight to nine hours of sleep each night, a good diet, and a minimum of 42 minutes of moderate-to-vigorous physical activity each day. Combining these measures leads to a 57% lower risk of heart attacks and strokes.Dr. Nicholas Koemel, the study's lead author, noted that "making a few small, combined changes is likely more achievable and sustainable for most people when compared with attempting major changes in a single behavior." He encouraged people to make small changes to their daily routine, as they can have a surprisingly large positive impact on cardiovascular health.Prof Emmanuel Stamatakis, a senior author of the study, plans to build on these findings to develop new digital tools that support people in making positive lifestyle changes and establishing sustained healthy habits.Commenting on the study, Emily McGrath, a senior cardiac nurse at the British Heart Foundation, said that "small tweaks – like getting a little more sleep, adding a few extra minutes of activity to your day or eating a bit more veg – can work together to have a meaningful positive impact on your heart health."
