Why does the war in Sudan persist three years after it began? According to the latest episode of Al Jazeera’s podcast The Take, the answer lies in the network of external actors that continue to fund and arm the warring factions – the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF). The episode, hosted by journalist Malika Bilal and featuring political analyst Dallia Abdelmoniem, explores how regional and global rivalries have turned Sudan into a proxy battleground. With the United States and Israel engaged in a broader confrontation with Iran, and tensions in the Strait of Hormuz inflating oil prices, the cost of fuel and food in Sudan has surged, worsening an already dire famine situation. Key insights from the discussion include: Foreign financing and arms supplies keep both the SAF and RSF operational, preventing a decisive military outcome. US‑Israel‑Iran dynamics divert international attention and resources, allowing the Sudanese conflict to fester. Rising global fuel prices driven by Strait of Hormuz instability increase transport costs, making humanitarian aid more expensive and less accessible. Food price spikes exacerbate famine risk for millions of displaced Sudanese, deepening the humanitarian crisis. The podcast also notes that without a coordinated diplomatic push to address the external backers and the broader geopolitical tensions, a sustainable cease‑fire remains unlikely. Production credits go to Tamara Khandaker (producer), with contributions from Noor Wazwaz, Sari el‑Khalili, Spencer Cline, Chloe K Li, and Tuleen Barakat. Editing was handled by Alexandra Locke, while Alex Roldan provided sound design and Hisham Abu Salah and Mohannad al‑Melhem managed video editing.

Bath Rugby, who recently overcame Northampton Saints in a thrilling quarter-final, have a contrasting style that could potentially counter Bordeaux's modus operandi. Bath's tighthead Thomas du Toit and scrum-half Finn Russell could provide a strong challenge to Bordeaux's backline.Exeter Chiefs also had a remarkable win in their Challenge Cup quarter-final, coming from behind to beat Benetton 44-41. Their ability to hang tough in the final quarter and secure crucial kicks will be essential in their upcoming match against Ulster.The semi-final matchups are set to be intense, with Bath facing Bordeaux Bègles and Exeter Chiefs taking on Ulster. Will Bordeaux continue their winning streak, or will one of these teams manage to pull off an upset?

The United Kingdom's decision to ban Israelis from attending the Royal College of Defence Studies (RCDS) over Israel's actions in Gaza has sparked concern within the college about its reputation. The Ministry of Defence (MOD) announced the ban in September after Israel planned a major ground assault on Gaza City.The British government made the decision amid widespread condemnation of Israel's escalation of the war. Previously unreported correspondence shows that the move prompted discussion within the RCDS about potential harm to its reputation as an institution that welcomes students of all backgrounds.RCDS commandant George Norton asked a senior military official, Tom Copinger-Symes, for help in shaping the public narrative while a government minister was preparing to answer a question about the ban in the UK's upper house of parliament. Norton sought to ensure that the public understood the college played no role in the decision.In an email, Norton told Copinger-Symes that it would be important for the government minister to highlight that the college does not invite or select participants in its courses, and that invitations were a government-to-government matter. He emphasized that the college's reputation as a welcoming institution could be harmed by the perception that it was deciding which countries to invite or not.The emails, obtained by Al Jazeera via a Freedom of Information request, reveal the college's efforts to distance itself from the government's decision. The MOD spokesperson stated that decisions about military education and training are made on a case-by-case basis and following robust assessment of benefits and risks.The UK-Israel relationship has been strained due to Israel's actions in Gaza, where over 72,000 Palestinians have been killed since Israel launched its military operation. The RCDS did not respond to a request for comment.

The article features three brainteasers with their respective solutions. The first puzzle involves a Navy admiral choosing between sending one ship with a P per cent chance of success or two ships each with a P/2 per cent chance of success. The solution reveals that sending one ship is always the better option.The second puzzle introduces two oracles, Randie and Rando, who answer questions differently. Randie responds randomly, while Rando decides to tell the truth or lie. The solution explains how to distinguish between them by asking a specific question that yields the same answer from both a liar and a truthteller.The third puzzle involves a mathematical problem where Johnny calculates 5548-5489 = 59 by incorrectly canceling out digits. A similar calculation XXYZ - XYZW is analyzed, and the solution reveals that Z and W are 8 and 9, respectively.

Tanya Khovanova has long been a leading voice in the world of recreational mathematics, authoring a popular blog and running the Number Gossip site where enthusiasts can inquire about any number.She now debuts her first book, Mathematical Puzzles and Curiosities, co‑written with fellow puzzle‑enthusiasts Ivo David and Yogev Shpilman. Published by World Scientific, the volume offers fresh challenges and inventive twists on classic problems.To give readers a taste, Khovanova selected three puzzles for the Guardian column:1. Battleships – As a naval admiral you must choose between sending a single vessel with a success probability of P % or two vessels each with a P/2 % chance, where the mission succeeds if at least one ship does. Which strategy maximises the odds?2. The Two Oracles – You face two respondents, Randie, who answers randomly, and Rando, who randomly decides to tell the truth or lie before each answer. Is there a method to distinguish them?3. Bad Maths – A student computes 5548 − 5489 as 59, claiming the “548” cancels out. He then experiments with a subtraction of the form XXYZ − XYZW (distinct digits) and observes the result is XW. How many digits in the new expression match those in the original calculation?Solutions to the trio were later posted online (update), but readers were urged to avoid spoilers until the scheduled reveal.Khovanova also reminds fans that she has been curating puzzles for the Guardian every other Monday since 2015 and welcomes new submissions via email.

At 19,000 miles above the lunar surface, the Artemis II astronauts heard the voice of Apollo‑13 commander Jim Lovell greeting them from beyond the grave, a message recorded shortly before his death at 97. Mission control transmitted the tribute on the morning of 6 April, when astronaut Reid Wiseman held a silk square bearing the original Apollo 8 patch—handed to him by Lovell’s son—before the crew’s launch. Launch director Charlie Blackwell‑Thompson secured a unanimous "go" from every console, a moment the author describes as a snapshot of humanity’s capacity to honor the past while reaching for the future. The ceremony stood in stark contrast to the Pentagon’s agenda. Two decades after a 2006 Iraqi kill‑board note reading “Let the bodies hit the floor,” the current defense chief pledged “death and destruction from the sky all day long” against Iran, a stance legal scholars warn could constitute a war crime. That rhetoric accompanies a proposed $1.5 trillion defense budget, including an additional $200 billion earmarked for operations against Iran—figures that dwarf NASA’s entire annual budget of $24.4 billion. Amid this fiscal disparity, crew members reflected on their place in history. Victor Glover, the first Black astronaut to travel deep space, described the view of Earth as an "oasis" in the void, while Christina Koch, the first woman to orbit the Moon, pressed her face to the window and formed a heart with her hands, calling the mission’s spirit "humility." Reid Wiseman watched the planet rotate beneath him, noting the sight of Africa, Europe, and the aurora‑lit north, saying it "paused all four of us in our tracks." Canadian astronaut Jeremy Hansen broke Jim Lovell’s 56‑year distance record and asked mission control to name a lunar feature after his late wife, Carroll. The crew agreed, designating a bright spot on the Moon as "Carroll," a tribute that will endure beyond any single lifetime. When Koch announced the spacecraft’s descent, she radioed, "We are now falling to the moon rather than rising away from Earth," a poetic reversal that underscored the mission’s symbolic return. The article recalls the author’s 2022 reflection on the James Webb Space Telescope, noting how humanity’s finest inventions now aim outward, seeking answers to our origins rather than turning inward toward conflict. Artemis II’s vessel, named Integrity, carried four breathing humans who, in a moment of collective grief, pressed their faces to the glass and imagined the faces of every loved one ever lived, captured in a single frame. Beyond the spacecraft, cultural threads wove through the mission: Hansen’s patch displayed the Seven Sacred Teachings of the Anishinaabe people, and the Chinese myth of Chang’e reminded viewers of the Moon’s timeless allure. As Carl Sagan famously wrote, "We are made of star‑stuff," the Artemis crew embodied that sentiment—not as passive observers, but as active participants in a fragile, hopeful narrative that rises above the relentless tally of bodies on Earth’s battlefields.

On a recent weekday evening, a special bus tour whisked art lovers through over twelve galleries and museums that stayed open until midnight, offering a late‑night glimpse of the Abidjan Art Week programme.The after‑hours event, dubbed the Night of the Galleries, was first trialled in January 2024 alongside the Africa Cup of Nations – a tournament that Côte d’Ivoire both hosted and won – and has become a staple of the festival’s third edition, which ran from Tuesday to Sunday.Since its inception, the week has broadened its footprint, moving beyond the city centre to include venues such as the La Rotonde des Arts contemporary‑arts hub in the Plateau district and the Adama Toungara Museum of Contemporary Cultures (MuCAT) in the working‑class neighbourhood of Abobo.Local collectors are emerging in force. MuCAT has hosted the Africa Foto Fair each year since 2022, and the Marché des Arts du Spectacle d’Abidjan – the city’s answer to the Dakar Biennale – is set to launch its 14th edition later this month.A graffiti festival launched two years ago has transformed the perception of street art, with vibrant murals now adorning the façade of the La Pyramide building and several upscale hotels in Plateau.Organisers stress that the festival’s growth should be independent of external validation. This year’s roster featured artists from Cameroon, the Democratic Republic of the Congo and Mali, and the number of participating galleries more than doubled compared with previous editions.Founder Yacouba Konaté, who also directs La Rotonde des Arts, highlighted the festival’s commitment to accessibility, arguing that art should not be seen as an elite pastime.The opening tribute honoured Simone Guirandou‑N’Diaye, a pioneering Ivorian art historian whose legacy lives on through Galerie LouiSimone Guirandou, now run with her daughter Gazelle.Among the week’s highlights, MuCAT presented Murmures d’Archives, a quieter, archival‑focused exhibition that concluded with an artists’ workshop and a DJ set.In the upscale Cocody district, New York‑based artist Ouattara Watts staged a solo show at Galerie Cécile Fakhoury, drawing the Ivorian diaspora into dialogue with the local scene. Watts explained that his work aims to transcend borders, describing it as “a vision that goes beyond any map – it is the cosmos that I paint.”

The Department for Culture, Media and Sport, acting on Historic England’s advice, has awarded Grade II* listed status to a limestone rubble barn on a grassy knoll in the Lake District, joining an elite roster that includes Battersea Power Station and the London Coliseum.Dubbed “Henry’s Castle,” the structure was most recently used as a shelter for livestock, but research suggests it may date back to the 14th century and originally served a high‑status function that remains unknown.Only 5.8% of England’s listed buildings achieve the Grade II* level, indicating they possess “more than special interest.” The barn’s unusual features – a corbelled chimney stack, a stepped garderobe, and a plastered interior showing signs of fire – set it apart from ordinary field barns.Historic England’s listing team leader, Sarah Charlesworth, described the building as “one of those rare structures that raises more questions than it answers,” underscoring its intrigue for scholars and visitors alike.Lake District National Park’s built‑environment adviser, Rose Lord, recalled her 2022 visit, noting that despite layers of animal manure the barn’s architecture hinted at something “very special” – a construction far beyond typical agricultural outbuildings.Four years of meticulous work by archaeologists, architects, and conservation engineers have restored the barn’s most striking element: an oak roof featuring a hand‑finished, chamfered and pegged central truss, a technique associated with high‑quality carpentry of the 14th or 15th centuries.Experts speculate on the barn’s original purpose, ranging from a defensive lookout or hunting lodge to a luxurious summer house. Historic England notes similarities to bastles – fortified farmhouses common along the Anglo‑Scottish border – though the building’s location south of the border makes a strict classification unlikely.Originally converted to domestic use in the 16th or 17th century and later repurposed as a field barn by the 19th century, the structure takes its name from former owner farmer Henry Willison.Lord called the new listing the “cherry on the cake” for the restoration project, highlighting that most buildings of comparable significance have already been recorded in earlier surveys. Interpretation panels and an owl‑nesting box are slated for installation in the coming weeks, adding educational and ecological value to the site.
