The biggest public backer of World Liberty Financial, the crypto venture co‑founded by the Trump family, has publicly accused the firm of embedding a covert "backdoor blacklisting" feature that allows it to freeze token holdings at will. On Sunday, blockchain entrepreneur Justin Sun posted on X, alleging that World Liberty’s smart contracts for the WLFI token contain a tool that can unilaterally freeze, restrict, or confiscate any user’s assets without cause or recourse. Sun did not provide evidence, but said his own wallet was locked in September, making him the "first and single largest victim" of the alleged mechanism. World Liberty responded on X, stating, "We have the contracts. We have the evidence. We have the truth. See you in court, pal," and directed observers to its own posts for clarification. The company’s official risk disclosures do note that it may block or freeze addresses deemed linked to illegal activity or terms violations – a practice also employed by other crypto issuers such as Tether. Sun, who invested tens of millions of dollars in WLFI and later increased his stake to at least $75 million according to his 2025 posts, has not shared the purported blockchain records that supposedly show his wallet being blacklisted by a single administrative account. World Liberty, launched in 2024, claimed it would empower small investors through a decentralized‑finance app that has yet to launch. Reuters analysis indicated the venture generated **more than $460 million** for the Trump family in the first half of 2025. In March, the U.S. Securities and Exchange Commission settled a 2023 lawsuit against Sun for $10 million, alleging fraud and the sale of unregistered crypto securities. Sun made no admission of wrongdoing. The dispute highlights the murky regulatory environment for crypto in the United States, where the SEC has limited jurisdiction and has declined to comment on the legality of token‑freezing practices.

A recent set of studies has brought to light a concerning issue in social science research: up to half of all results published in reputable journals cannot be replicated by independent analysis. This problem is part of a broader challenge affecting various research fields, most notably social sciences and psychology, though concerns have also been raised in areas of biomedical research. The latest work, part of a seven-year project called Systematizing Confidence in Open Research and Evidence (Score), analyzed 3,900 social science papers. It found that newer papers and those published in journals requiring extensive sharing of underlying data were more likely to be reproduced. Additionally, medical research faces its own set of constraints, such as differing patient caseloads and limited sample sizes, which can make it resemble social sciences more than laboratory physics. Policymakers should be cautious of claims that don’t have a wide and robust base of evidence. The issue of reproducibility is crucial, as it looks at whether results can be recreated from the same data and methods, while replication tests whether the finding holds for new data in different contexts. However, politicians have increasingly looked to turn uncertainty into denial and recast normal scientific uncertainty as evidence of failure. Large-scale verification projects, like those undertaken by Score, are few and far between. Most academic researchers prioritize work that is more likely to enhance their careers. AI may help in deciding what to test, but it can’t reduce the costs and time involved in duplicating a piece of research. Not every failed replication signals a crisis; some findings don’t matter much, and replication studies can themselves be flawed. Greater transparency makes outright fraud more difficult and allows errors to be identified. Some argue that research “ultimately autocorrects,” but the long-term solution — shifting incentives so existing results are tested — would increase confidence. This requires restructuring of research culture and funding. For now, it remains largely notional. These studies should strengthen the case for change and serve as a warning. Social science is a powerful tool for understanding the world – and that trust will be built by acknowledging uncertainty, not repudiating it.

The EU's new entry-exit system (EES) has caused significant delays at several European airports, with travellers waiting up to three hours at border checks. The system, which came into effect on Friday in the Schengen countries, requires passengers from non-EU countries to register their personal information and biometrics at the border.Passengers in airports in countries such as France, Germany, Belgium, Italy, Spain, and Greece are experiencing several hours of waiting at border checks, according to the Airports Council International (ACI) body. Olivier Jankovec, the director of the ACI European division, warned that the situation will be "simply unmanageable" in the coming weeks and peak summer months.The EES has been gradually introduced since October and has already caused long delays at some airports. On Sunday, the BBC reported that more than 100 passengers were unable to board an easyJet flight from Milan to Manchester before it took off due to delays at passport desks.Airport representatives and the European Commission held a meeting to discuss problems with the system on Tuesday. The ACI has asked to extend existing exemptions and the power to fully suspend the new checks. Jankovec told the FT that the ACI needed the ability to "fully suspend EES registration whenever there are excessive waiting times at border control that are just unmanageable".A spokesperson for the European Commission said that the system is working well, with an average registration time of 70 seconds per passenger. However, the ACI has claimed that it can take up to five minutes. The commission said that there were a "few member states where technical issues have been detected" but that they "are being addressed".The EES has registered more than 52m entries and exits, as well as more than 27,000 refusals of entry, since its introduction in October. Almost 700 people were identified as posing a security threat.

President Donald Trump announced on Fox Business that he will dismiss Federal Reserve Chair Jerome Powell if the central‑bank chief does not vacate the post by the statutory end of his term on May 15. “I’ll have to fire him, OK, if he’s not leaving on time,” Trump said, adding that he had previously held back the decision to avoid controversy. Powell, who has just over a month left in his tenure, has repeatedly been criticized by Trump for what the president calls a “bad job” and for refusing to lower interest rates despite Trump’s repeated demands since his return to the White House in January 2025. In January, Trump nominated former Fed governor Kevin Warsh to replace Powell. Warsh, known for his criticism of the Fed’s relatively high rates, is expected to align more closely with Trump’s push for rate cuts. His confirmation hearing before the Senate Banking Committee is slated for April 21, but the outcome remains uncertain. Republican Senator Thom Tillis of North Carolina, a member of the banking committee, has signaled he will block Warsh’s nomination until the Department of Justice concludes its criminal investigation into alleged misconduct surrounding the Fed’s headquarters renovation in Washington, D.C. Tillis described the probe as “reaching the point of absurd,” yet insists the investigation must be resolved before moving forward. The probe appears active: prosecutors made an unannounced visit to the construction site this week, as reported by the Wall Street Journal, underscoring the seriousness of the inquiry. During the same interview, Trump dismissed the investigation’s relevance, claiming the project was “probably corrupt, but what it really is is incompetence,” and questioned whether a $25 million renovation could balloon to a $4 billion expense. Powell responded in January with a rare public rebuke, labeling the investigation a “pretext” aimed at pressuring the Fed to lower rates. He warned that political intimidation could jeopardize the Fed’s ability to set monetary policy based on economic evidence. The legal backdrop adds another layer of uncertainty. The Supreme Court has yet to rule on Trump’s authority to fire a Fed board member without cause—a question that resurfaced after the president’s attempted removal of Fed governor Lisa Cook last summer. Justices appeared skeptical of such unilateral action during oral arguments in January. With the Fed’s independence at stake, the coming weeks will determine whether Trump’s threat translates into action, whether Warsh can secure Senate confirmation, and how the renovation investigation will influence the broader debate over political interference in U.S. monetary policy.

Snap Inc, the parent company of Snapchat, has announced plans to lay off 1,000 workers, or 16% of its employees, citing rapid advancements in artificial intelligence as the reason. The social media company informed staff of the decision in an internal memo on Wednesday.The layoffs are part of a wave of tech industry job cuts in the past year, with many firms, including Microsoft, Amazon, and Oracle, blaming AI for the reductions. Snap Inc's CEO, Evan Spiegel, claimed that the layoffs would help the company move towards profitability and suggested that AI could fill the gap left by human labor.In his memo to staff, Spiegel wrote: “While these changes are necessary to realize Snap’s long-term potential, we believe that rapid advancements in artificial intelligence enable our teams to reduce repetitive work, increase velocity, and better support our community, partners, and advertisers.”The company, which employed around 5,200 people as of December last year, had also posted 300 open roles that will no longer be filled. Snap's stock rose around 6% in early trading following the news of the layoffs.The move has sparked concerns about the impact of AI on the labor market, with some experts and workers accusing firms of “AI-washing” layoffs to posture for investors and the market. However, top AI firms such as OpenAI and Anthropic have launched a charm offensive to address AI's potentially harmful effects on the labor market.

Manchester United's Harry Maguire will miss his team's upcoming match against Chelsea due to an additional one-match ban imposed by the Football Association. The ban comes as a result of Maguire's reaction to being sent off during a match against Bournemouth last month.The 33-year-old defender was shown a red card at the Vitality Stadium for a foul in the area on Evanilson, which led to Bournemouth sealing a 2-2 draw. Following the incident, Maguire allegedly made a comment towards the officials, stating they were 'a joke.'The FA's written reasons confirmed that the fourth official, Matthew Donohue, submitted an Extraordinary Incident Report Form, claiming Maguire shouted: 'You're a joke. You're all a fucking joke.' Maguire, however, claimed he said 'something along the lines of 'it is a fucking joke.''As a result, Maguire has been imposed a one-match suspension and a £30,000 fine by an independent Regulatory Commission. This suspension adds to the absence of fellow centre-backs Matthijs de Ligt and Lisandro Martínez, potentially leading to young players Ayden Heaven and Leny Yoro lining up at the heart of defence against Chelsea.

The literary world was recently abuzz with the news that critically acclaimed author Helen DeWitt had declined a $175,000 Windham-Campbell prize due to its onerous promotional requirements. The prize, which aims to give recipients the financial freedom to focus on their work, came with obligations that DeWitt found unsustainable, including six to eight hours of filming.This decision has ignited a fierce debate about the pressures of self-promotion in the publishing industry and the challenges faced by authors who are unable to meet these demands due to disability, chronic illness, or other personal circumstances. DeWitt's stance has been praised by some as a principled refusal to play the self-promotion game, while others have criticized her as entitled or spoiled.The Windham-Campbell prize is one of the most prestigious literary awards, recognizing eight writers each year for their life's work. This year's winners include Gwendoline Riley, an author known for her nuanced explorations of family relationships. Riley's win is a testament to the prize's ability to shine a light on talented writers who may have been overlooked.The controversy surrounding DeWitt's decision highlights the precarious nature of a literary career. With average author earnings plummeting and the industry becoming increasingly professionalized, many writers are finding it difficult to make a living from their work. The emphasis on self-promotion can be particularly challenging for authors who are neurodivergent or have disabilities, as it can exacerbate existing difficulties.DeWitt's experience has sparked a wider conversation about the need for greater inclusivity and support in the publishing industry. As one author noted, the art world is ahead of publishing in terms of facilitating access and assistance for artists with disabilities. The industry must adapt to accommodate writers with diverse needs and ensure that opportunities are accessible to all, regardless of their abilities.In a surprising twist, DeWitt has since announced that she has received a $175,000 grant from a conservative university thinktank with no strings attached. This development has raised questions about the role of philanthropy in supporting literary talent and the complexities of author promotion in the modern publishing landscape.

Miami Heat coach Erik Spoelstra expressed strong disapproval of LaMelo Ball's actions during Tuesday night's play-in tournament game against the Charlotte Hornets. Spoelstra stated that Ball should have been ejected for tripping Bam Adebayo, which resulted in Adebayo's injury and subsequent absence from the game.The incident occurred early in the second quarter when Ball appeared to reach out and grab Adebayo's left leg as he fell to the floor after missing a shot. This led to Adebayo falling on his back and eventually walking to the locker room under his own power, though he did not return to the game.Spoelstra emphasized that there is no place in the game for such actions, describing the play as 'stupid' and 'dangerous'. He also mentioned that it was not an excuse for the Heat's loss but highlighted the significance of Adebayo's absence.LaMelo Ball, who scored 30 points and made the go-ahead layup in overtime, apologized for his role in Adebayo's injury. He claimed he was disoriented after being hit in the head during the drive and did not intentionally grab Adebayo's leg.The play was not reviewed or penalized in real-time, with official Zach Zarba explaining that the window to review the play was closed due to the fast-paced nature of the game and the lack of an immediate whistle.The incident has implications beyond the game, with Zarba indicating that the league operations will determine if Ball should be assessed a flagrant foul in the coming days.

Leeds, the largest European city still without a mass‑transit system, may finally see a tram line – but not before the late 2030s. The latest West Yorkshire Mass Transit plan, championed by combined‑authority mayor Tracy Brabin, received a fresh £200 million in development funding, part of a broader £2.1 billion allocation for the region.City council leader James Lewis, who began his career on a 1993 work‑experience placement with the council’s highways department, says the new scheme differs from past attempts. Instead of squeezing trams onto existing bus routes, the proposal envisions a dedicated line that could “float over or under the M621 motorway, similar to the Docklands Light Railway,” linking the White Rose shopping centre, Elland Road stadium, Leeds railway station and St James’s Hospital.The Treasury’s independent review, however, forced the government to demand a fresh business case that proves the need for trams rather than buses. This procedural hurdle has added roughly two years to the timetable, pushing the projected opening into the late 2030s. Brabin acknowledges the setback, noting critics now claim the project is effectively “cancelled,” but she insists the work is merely delayed, not abandoned.Leeds’ transport woes date back to the removal of its historic double‑deck tram network in 1959 and the construction of the M621, which many locals blame for isolating the city’s south side. A 2025 Treasury review warned that previous “Supertram” proposals failed because they could not demonstrate sufficient value for money, leading to the withdrawal of funding in 2005 and the abandonment of a trolley‑bus plan in 2016.Supporters argue the tram is essential for unlocking massive regeneration. Leeds United investor Pete Lowy predicts the line could catalyse up to £1 billion of investment, including 2,500 new homes, retail and leisure space, and a 15,000‑seat stadium expansion. Northern Powerhouse Partnership chief executive Henri Murison points to the emerging South Gateway development in Bradford as evidence that transport‑led investment is already materialising.Critics remain sceptical. Leeds University transport professor Greg Marsden questions how an 18‑year‑long project can still be justified, while local residents voice doubts that a tram can ever be built in a city they consider “not big enough.” Tom Forth, co‑founder of data‑city firm Information Group, blames centralised decision‑making in London, arguing that devolved funding would accelerate delivery.In the meantime, the council is focusing on improving bus services, which will come under public control in 2027. Centre for Cities analyst Rob Johnson notes that increasing bus frequencies could immediately benefit the 390,000 residents currently poorly connected, potentially delivering more mobility gains than a tram in the short term.Nevertheless, Brabin maintains that trams are “more attractive, carry more passengers, and generate more jobs and growth” than buses, and she reaffirms her promise: “I promised a tram, and a tram is what we’re going to get.” The pledge to have “spades in the ground” by 2028 for preparatory works remains on the table, even as the project navigates the Treasury’s stringent process.
