The piece examines the various parties that are maintaining the momentum of Sudan's war, shedding light on the intricate network of local militias, regional powers, and external stakeholders involved. While details remain limited, the analysis underscores how these actors collectively contribute to the persistence of violence, influencing both the humanitarian situation and regional stability.

The Atlantic meridional overturning circulation (Amoc), a critical component of the global climate system, is at risk of collapse, with new research indicating a significantly higher likelihood than previously thought. This current system plays a vital role in regulating global climate patterns, and its collapse would have catastrophic consequences for Europe, Africa, and the Americas.Scientists have long been monitoring the Amoc's decline, which is primarily caused by rising air temperatures in the Arctic due to global heating. The Amoc's slowdown allows more rainfall to accumulate in the salty surface waters, making it less dense and further slowing the sinking, creating a feedback loop.The research, published in Science Advances, combined real-world ocean observations with climate models to determine the most reliable predictions. The findings suggest an estimated slowdown of 42% to 58% by 2100, a level almost certain to end in collapse. This is a concerning development, as a collapse would shift the tropical rainfall belt, plunge western Europe into extreme cold winters and summer droughts, and add 50-100cm to already rising sea levels around the Atlantic.Experts, including Dr. Valentin Portmann and Prof. Stefan Rahmstorf, emphasize the gravity of the situation, with Rahmstorf warning that the 'pessimistic' models, which show a strong weakening of the Amoc by 2100, are unfortunately the realistic ones. He added that he is increasingly worried that the Amoc shutdown tipping point may be passed in the middle of this century, which is quite close.The Amoc's collapse would have severe impacts on global climate patterns, and scientists stress that it must be avoided at all costs. The research highlights the need for urgent action to mitigate the effects of climate change and prevent such a catastrophic event.

Gray whales have historically been a rare sight in the San Francisco Bay. They migrate over 10,000 miles from Mexico's Baja California to the Arctic region, seldom stopping in the busy shipping corridor for prolonged periods. However, in recent years, this has changed in a dire way.A new study published in the journal Frontiers in Marine Science has found that gray whales in the bay have been dying at alarming rates, largely due to collisions with vessels. Eastern North Pacific (ENP) gray whales began to appear more frequently in the well-trafficked maritime corridor around 2018.According to researchers, at least 18% of gray whales that entered the bay from 2018 to 2025 have died. They determined that for more than 40% of the whale carcasses, the cause of death was blunt force trauma consistent with vessel strikes, prompting calls for renewed efforts to help avoid more fatal collisions.“It was historically very unusual for them to enter the bay, especially for longer amounts of time or consistently year after year,” said Josie Slaathaug, lead author of the study. There are whale subgroups known to hunt for food south of the Arctic, but a majority of the recently spotted whales feeding in the bay were not a part of these foraging clusters.A wave of new whale presence had not been observed in the waters since the late 1990s. Researchers have theorized that Arctic warming is disrupting food availability for the whales, driving them to hunt in new places such as the bay, although it remains unclear what exactly they may be eating there.Their potential new feeding corner, though, is a major shipping route. The true mortality rate for whales in the bay may be higher, hovering somewhere from 40% to 50%, Slaathaug said.In recent years, there have been several reports of dead whales that wash up on Bay Area beaches. The ENP gray whale population has been in decline due to malnutrition and starvation from climate-driven prey shifts in the Arctic. The Southwest Fisheries Science Center estimated a population total of about 13,000 whales, its lowest count since 1970.“It’s not unique to their migratory corridor that a lot of whales are dying,” Slaathaug said. “What is unique about San Francisco Bay and this study was that there was such a clear emerging cause of death.”Some local efforts are under way to reduce vessel collisions. The Marine Mammal Center has developed a program called Whale Smart, to educate vessel operators in the San Francisco Bay on how to interpret whale behavior to avoid close encounters.In Alaska, where vessels also pose a threat to the whale population, one fleet company partnered with WhaleSpotter, a company that uses AI and thermal imaging to detect the presence of whales, so they can change course well in advance.Last year, the Center for Biological Diversity, a conservation group, sued the US Coast Guard, which regulates vessel traffic off the California coast, for failing to analyze how vessel routes may harm whales and sea turtles.“This most recent study about the gray whales reaffirms that we have way underestimated the problem and we are not managing human activities well enough to avoid the whales,” said Catherine Kilduff, senior attorney at the center.Federal action is needed to reduce the fatal collisions, Kilduff said. According to the Endangered Species Act, the coast guard should be consulting with the National Marine Fisheries Service when setting shipping lanes to assess impact to marine wildlife.Kilduff also suggested mandatory speed limits for vessels. “There are voluntary speed reductions on the west coast, but there is evidence that those aren’t effective. The compliance rate isn’t high enough,” she said.A 2022 study co-authored by the National Oceanic and Atmospheric Administration found that the average speeds of large vessels had decreased from 2010 to 2019 in voluntary speed reduction zones. But, researchers determined that the cooperation rate of roughly 50% was lower than the amount needed to reduce vessel strike-related mortality to a level that maintains a sustainable whale population.“These whales are using the oceans in such a sophisticated way. We can learn so much from them, and if we can figure out ways to avoid killing them, I know that they’ll come back to healthy population levels,” Kilduff said.

In a landmark decision, a Manhattan federal jury determined that Live Nation and its Ticketmaster subsidiary wield a monopolistic grip on major concert venues across the United States. The four‑day deliberation ended Wednesday with a finding that the ticket‑selling platform had overcharged buyers by $1.72 per ticket, a figure that will now be used by a judge to calculate total damages. The case, originally spearheaded by the federal government and later joined by dozens of states, accused Live Nation of leveraging its extensive venue network to stifle competition. Plaintiffs argued that the company barred venues from using alternative ticket sellers and retaliated against those that attempted to do so. Attorney Jeffrey Kessler, representing the states, called Live Nation a “monopolistic bully” that inflates prices for concertgoers. He cited the company’s control of 86% of the concert‑ticket market and 73% of the combined concert‑and‑sports market, underscoring the breadth of its influence. Live Nation, which reported over $22 billion in annual revenue, rejected the monopoly label, insisting that pricing decisions rest with artists, sports teams, and venue owners. Company counsel argued that the firm’s size reflects “excellence and effort,” not antitrust violations. The jury’s finding arrives amid a broader regulatory push. In 2024, the Federal Trade Commission required Ticketmaster to disclose ticket fees up front, prompting the company to eliminate a post‑checkout processing charge. However, a recent Guardian investigation revealed that Ticketmaster introduced alternative fees to offset lost revenue, raising questions about compliance with FTC rules. Earlier, the Department of Justice settled with Live Nation under the Trump administration, creating a $280 million settlement fund for participating states. The agreement also imposed caps on service fees at select amphitheaters and opened the door—though not the obligation—for venues to work with Ticketmaster rivals such as SeatGeek and AXS. More than 30 states declined the settlement and pursued the trial, arguing that the federal government’s concessions were insufficient. During the proceedings, Live Nation CEO Michael Rapino testified, including about the 2022 Taylor Swift ticket fiasco, which he attributed to a cyber‑attack. Internal communications from Live Nation executive Benjamin Baker surfaced, in which he described certain pricing practices as “outrageous” and disparaged customers as “so stupid,” later apologizing for the “very immature and unacceptable” remarks. Live Nation has announced its intention to appeal the verdict, stating confidence that the ultimate outcome will align with the original DOJ settlement framework. The case continues to spotlight the tension between dominant market players and antitrust enforcement in the live‑entertainment industry.

The future of the LIV Golf series hangs in the balance after Saudi Arabia’s Public Investment Fund (PIF) signaled a possible withdrawal of its multi‑billion‑dollar support. Executives were summoned to a high‑stakes meeting in New York this week, a development that follows growing speculation that the rebel tour could be shut down. While the fifth season’s sixth event in Mexico City is set to proceed on Thursday, the tournament is being eclipsed by reports that PIF intends to cut the tour’s funding. The tour has already faced challenges securing a merger with the PGA Tour despite a three‑year “framework agreement,” and the funding pull would exacerbate its financial strain. According to the PIF’s newly released five‑year economic strategy, the fund is prioritising sustainable domestic investments and has omitted sport from its seven key focus areas. This shift signals a move away from the “free‑spending, disruptive internationalism” that characterised the launch of LIV Golf in 2021. Since its inception, PIF has poured over $5 bn into the tour, but this year prize money and bonus payouts have already been slashed. High‑profile players such as Phil Mickelson, Dustin Johnson, Jon Rahm, Sergio García and Bryson DeChambeau initially defected from the PGA and DP World Tours, yet recent defections back to the PGA—including Brooks Koepka and Patrick Reed—highlight the tour’s precarious position. DeChambeau has yet to sign a new contract. A source familiar with the Saudi Ministry of Sports confirmed that the fund is redirecting its sports budget toward football and esports, with golf no longer a priority. The same source noted that PIF is ending its partnership with the Women’s Tennis Association, and the three‑year WTA Finals deal in Riyadh will not be renewed after its November expiry. The rumours ignited on Tuesday after journalist Ryan French posted on X that multiple sources warned of a “bombshell announcement” on LIV’s future, later suggesting the tour might be shutting down. LIV officials and players have not received any formal update. In Mexico, Sergio García told reporters they have only heard the same message from PIF chief Yasir al‑Rumayyan at the start of the year: that the project is a long‑term commitment, and that rumours are inevitable. Technical glitches, including an alleged power failure at the venue, forced the cancellation of pre‑tournament press conferences on Tuesday. Nevertheless, the pro‑am competition resumed on Wednesday at 8:30 a.m. local time, indicating that day‑to‑day operations continue despite the uncertainty. The outcome of the New York meeting could determine whether LIV Golf survives as a viable alternative to traditional tours or becomes another casualty of shifting Saudi investment priorities.

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.

At the Metropolitano, Barcelona appeared to be in control early on, with Lamine Yamal delivering a pinpoint cross that set up a near‑certain goal for Fermín López. The strike was thwarted by a spectacular save from Juan Musso, leaving López drenched in claret. Had the ball found the net, Barcelona would have taken a 3‑0 lead and an advantage in the tie after already scoring through Yamal and Ferran Torres in the opening half‑hour.The deadlock was broken when Charlton‑trained forward Ademola Lookman netted the decisive goal, sending Atlético Madrid into the Bigger Cup semi‑finals. The victory sparked an exuberant reaction from coach Diego Simeone, who praised his side’s enthusiasm and readiness for the next challenge, hinting at a possible showdown with Arsenal or Sporting.In the aftermath, Barcelona winger Raphinha launched a scathing critique of referee Clément Turpin, alleging that the officiating had robbed his team not only in the second leg but also in the first. The Brazilian warned that his comments could land him on UEFA’s disciplinary “naughty step,” with precedent suggesting a suspension of at least three matches for such language.The controversy deepened as Turpin refrained from issuing any bookings to Atlético players and denied Barcelona what they believed were two clear penalty opportunities across both legs. Musso, who had earlier saved López’s chance, dismissed the accusations, emphasizing that the match was decided on the pitch and that disciplinary actions are part of the game’s reality.Further coverage of the European fixtures, including live updates from the Bigger Cup quarter‑finals and analysis from Guardian experts, is available on the publication’s football portal.

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.
