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.

Senator Bernie Sanders, a proud Jewish American, has spoken out against the inhumane actions of Israel and its leader, Benjamin Netanyahu. He emphasizes that criticizing Israel's actions is not antisemitic, but rather a necessary stance against violations of international law.Sanders highlights the devastating impact of Israel's actions in Gaza, where over 72,000 Palestinians have been killed and over 170,000 wounded, mostly women, children, and the elderly. He also notes the destruction of almost all of Gaza's infrastructure, including water and sewer systems, and the demolition of every university and hundreds of schools.In the West Bank, Israeli soldiers and settlers have killed 1,071 Palestinians, including 233 children, and demolished over 6,000 Palestinian homes. Sanders argues that these actions are not just extremist settler behavior, but government policy, with Netanyahu's security cabinet approving sweeping changes to the West Bank's legal status.Sanders announces that he will force a Senate vote on two Joint Resolutions of Disapproval to block arms sales to Israel, including $151.8m in 1,000-pound bombs and $295m in bulldozers used for demolishing homes. He hopes his colleagues will join him in supporting these resolutions, citing plummeting support for Israel among Americans, especially young people.

An international conference in Berlin has yielded pledges of over £1 billion to support Sudan, a country devastated by three years of conflict. The funding, which exceeds the initial target of $1 billion (£740 million) set by German ministers, aims to alleviate the world's largest humanitarian crisis.The financial commitments will help address a chronic humanitarian funding shortfall in Sudan, where two-thirds of the population, or 34 million people, require assistance. The crisis has been exacerbated by ongoing conflict between the paramilitary Rapid Support Forces (RSF) and the army.UN Secretary-General António Guterres urged international delegates to take action, highlighting 'credible allegations of the gravest international crimes' and the need for an immediate cessation of hostilities. He emphasized that 'funding alone cannot substitute for peace.'The UK Foreign Secretary, Yvette Cooper, called for a concerted international effort to stop the flow of arms into Sudan, while the US emphasized its commitment to a humanitarian truce that would allow aid to reach those in need.Despite the funding pledges, the prospect of peace remains distant, with scant progress reported on ceasefire talks and neither of Sudan's warring parties attending the conference.

Negotiations between Washington and Tehran are expected to resume in Islamabad within days, placing President Donald Trump under intense pressure to deliver an Iran accord that can be credibly billed as superior to the 2015 Joint Comprehensive Plan of Action (JCPOA) brokered by former President Barack Obama. Two tests dominate the diplomatic calculus: the deal must demonstrably exceed the Obama agreement, and it must ensure that Iran derives no lasting strategic advantage, particularly over the vital Strait of Hormuz. While direct comparisons with the 159‑page JCPOA are imperfect—given the evolution of Iran’s nuclear program and the emergence of non‑nuclear concerns—the Trump team is framing its objectives around four pivotal issues. 1. Enrichment suspension: In Geneva on 26 February, the U.S. demanded a 10‑year freeze on all domestic uranium enrichment, a figure Iran’s foreign minister deemed unrealistic beyond three years. In Islamabad, the U.S. escalated the ask to a 20‑year suspension, yet Trump publicly dismissed even that, insisting on a permanent ban. The practical timeline for Iran to restart enrichment after the damage to its facilities remains uncertain. 2. Highly enriched uranium (HEU) stockpile: The original JCPOA capped uranium enrichment at 3.65% and limited the stockpile to 300 kg. Iran now holds 440.9 kg of 60%‑enriched uranium—a material that can be rapidly converted to weapons‑grade (90%)—mostly stored as UF₆ gas in scuba‑tank‑sized canisters. Tehran offered to down‑blend this stockpile to 3.67% in an irreversible process, mirroring the 2015 deal’s provisions. The U.S., however, is pressing for the entire stockpile to be removed from Iran under American supervision, a stance that raises questions about the relative merits of in‑country down‑blending versus export. 3. Sanctions relief: The JCPOA promised the release of roughly $100 billion in frozen Iranian assets and the lifting of oil trade restrictions, while retaining sanctions on terrorism, human rights, and missile proliferation. In the Geneva framework, over 80% of sanctions would be lifted, leaving only human‑rights‑related measures. Trump’s administration, wary of political backlash, seeks to attach conditions on how Iran can spend the relief, a demand Tehran rejects, insisting on a permanent, irreversible lifting of sanctions. 4. Non‑nuclear issues: Trump has repeatedly criticized the JCPOA for isolating Iran’s nuclear program from its broader regional behavior. The current negotiations must grapple with Iran’s ballistic‑missile program, support for proxy forces, and the strategic future of the Strait of Hormuz. Iranian officials are divided: one camp favors leveraging the strait for immediate revenue and national pride, while another views it as a diplomatic lever to secure a lasting ceasefire and security guarantees. The confluence of these challenges creates a “marshmallow test” for both sides—whether they can forgo short‑term temptations in favor of a durable, long‑term settlement. As the Trump presidency approaches its final year, the ability to craft a deal that convincingly outperforms the Obama era while addressing the expanded nuclear and geopolitical landscape will determine the legacy of U.S. policy on Iran and its impact on regional stability.

A recent court of appeal decision suggesting it's impossible to determine which identical twin fathered a child has sparked controversy among genetics experts. Prof Michael Krawczak from Kiel University, Germany, argues that this is not the case. According to Krawczak, the germ cells of monozygotic twins differ with sufficient probability and to a sufficient degree to allow their respective children to be clearly assigned to either of them using molecular genetic techniques.Krawczak and his colleagues first proposed this approach in 2012 and demonstrated its practical feasibility in 2018. While the required molecular genetic testing is costly, currently in the five-figure range, Krawczak questions whether these costs would be a significant enough barrier to preclude genetic testing, given the potential consequences of inaction for those involved.The court's assertion that it was "not possible" to determine paternity in such cases is therefore disputed. Krawczak's comments highlight the potential for genetic testing to resolve paternity disputes in cases involving monozygotic twins, offering a solution to a complex and sensitive issue.

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.

Sir Keir Starmer cannot be blamed for the economic consequences of a war he did not start, but he needs to have a plan in place for a severe and prolonged crisis. The public needs to see that the government is proactive and prepared to address the challenges ahead.

British Chancellor Rachel Reeves has stepped up her criticism of Donald Trump's war on Iran, describing it as a 'mistake' that has destabilized the global economy and damaged living standards around the world.In a marked fraying of the transatlantic relationship, Reeves said Trump's decision to break off from diplomatic talks with Iran and launch airstrikes seemed to have left the president in a worse place than he started.“I think it was a mistake to end those [talks with Iran] and to enter into conflict, because I'm not convinced that we are safer today than we were a few weeks ago,” she told an event in Washington.Reeves' comments added to blunt criticism of Trump she made just before flying out on Tuesday, when she expressed frustration at the 'folly' of his decision to go to war without a clear exit plan.The criticism adds to an increasingly tense atmosphere between Downing Street and the White House, with Trump's attacks on Prime Minister Keir Starmer becoming increasingly personal.The IMF warned on Tuesday that a further escalation in the Iran war could trigger a global recession that would affect the UK more than any of the other G7 nations.Reeves called for the urgent reopening of the strait of Hormuz to calm global energy prices, saying the lack of clear US targets in negotiations with Iran had worsened the situation.“We had the waterway open a few weeks ago. So, if now the objective is to reopen the strait of Hormuz? Well it was open at the beginning of this conflict,” Reeves added.Reeves said she had come to the IMF meetings to “deliver that fair message” that the conflict in the Middle East was hitting living standards worldwide and required urgent de-escalation.
