A remarkable fossil discovery in Victoria, Australia, has revealed that giant echidnas once roamed the region. The Owen's giant echidna, Megalibgwilia owenii, lived during the Pleistocene epoch, which began 2.5 million years ago.The fossil, discovered in the Buchan cave complex in East Gippsland, is a significant find, as it fills a 1,000km gap in the species' known distribution. Previously, specimens of the extinct monotreme had been found across Australia, from Western Australia to Tasmania, but mysteriously absent from the fossil record in Victoria.The Owen's giant echidna was about twice the size of Australia's modern echidnas, growing up to 1 metre long and weighing up to 15kg. Its skeleton is much more robust than that of comparably sized animals, with deeper, more prominent muscle scars and larger attachments for ligaments, indicating it was using much greater force when interacting with the landscape.According to Tim Ziegler, the collection manager of vertebrate palaeontology at the Museums Victoria Research Institute, the fossil was likely used for digging for buried larvae, larger prey of beetles, or bogong moths, or tearing tree bark to access food.The research, published in Alcheringa: An Australasian Journal of Palaeontology, provides new insights into the distribution and habitat of the Owen's giant echidna during the ice age.

Peter Magyar, the leader of the Tisza party, announced a comprehensive reform agenda hours after his coalition was declared the winner of Hungary’s parliamentary election, ending Viktor Orban’s 16‑year rule. He emphasized that his government will work to restore the rule of law, plural democracy and a system of checks and balances that he says were eroded under the previous administration.At a news conference, Magyar detailed plans for a new anti‑corruption office and a separate body to oversee government spending, aiming to curb the graft that plagued the former regime. He also announced a constitutional amendment that will limit future prime ministers to two terms, a direct response to Orban’s repeated changes to the constitution designed to extend his hold on power.Regarding foreign policy, Magyar pledged that Hungary will remain a committed member of both the EU and NATO, describing these alliances as essential guarantees of peace. He vowed to phase out dependence on Russian oil and gas by 2035 and to pursue a cooperative, rather than confrontational, dialogue with Brussels.The new government is expected to unlock roughly €18 billion in EU funding, and Magyar highlighted that the parliamentary shift could also release a €90‑billion loan package for Ukraine that Orban had blocked a month earlier.Magyar’s position on Ukraine is nuanced. He called the country “the victim in the war” and said he would press President Vladimir Putin to end hostilities, yet he maintained that “fast‑tracking Ukraine’s EU accession is completely out of the question while the war continues.” He added that the restoration of ethnic Hungarian minority rights in Ukraine would be a precondition for deeper ties.On trans‑Atlantic relations, Magyar affirmed that the United States remains “a very important partner” and expressed a desire for “good relations” with the Trump administration, noting the recent visit of U.S. Vice President JD Vance to Budapest.Domestically, Magyar called on President Tamas Sulyok to expedite the transfer of power and urged the president to resign, reminding readers that the president must convene a new parliament within 30 days, after which lawmakers will elect the new prime minister.

The Iranian judiciary announced on Monday that the assets of Zahra Ghanbari, captain of Iran’s women’s national football team, have been released following a court decision. The assets had been frozen earlier after she was listed among alleged “traitors” for seeking asylum in Australia.According to the state‑run Mizan news agency, the release came after Ghanbari submitted a “declaration of innocence” and demonstrated a change in behaviour, prompting officials to lift the seizure.Ghanbari was part of a group of six players and one staff member who fled to Australia in March, after the team’s refusal to sing Iran’s national anthem during the AFC Women’s Asian Cup sparked a media backlash. Australian Home Affairs Minister Tony Burke had publicly offered asylum to the entire delegation, warning they could face reprisals on return.Within weeks, five of the athletes, including Ghanbari, abandoned their asylum applications and returned to Iran. They were greeted with a hero’s welcome at a ceremony in central Tehran on March 19, and the court subsequently moved to restore their frozen assets.The asset release follows a broader crackdown that began after the outbreak of the US‑Israel war on Iran on February 28, during which more than 2,000 Iranians were reported killed. Iranian state media published a list of individuals deemed “traitors,” leading to the freezing of their property and bank accounts.In interviews with Al Jazeera, two of the returning players described the intense pressure they faced, noting that any misstep could have severe personal and professional consequences. “Every decision felt like a life‑or‑death choice for my family and my career,” said Mona Hamoudi, one of the athletes.Human‑rights groups have repeatedly warned that Iranian authorities use tactics such as asset seizure, family intimidation, and legal threats to deter athletes from defecting or speaking out. The case of Ghanbari underscores how sports can become a flashpoint for broader geopolitical tensions.Only two members of the original squad remain in Australia, where they have continued training with Brisbane Roar, while the rest of the team prepares for upcoming domestic competitions under heightened scrutiny.

The U.S. military announced that, starting at 14:00 GMT on Monday, it will enforce a blockade of every Iranian port, a step taken after President Donald Trump ordered a naval closure of the Strait of Hormuz—the waterway through which roughly one‑fifth of global crude oil normally flows. The blockade comes on the heels of stalled peace negotiations in Islamabad, where talks between Washington and Tehran collapsed without an agreement despite a prior cease‑fire pledge. Trump’s escalation has already driven crude prices above $100 per barrel and unsettled Asian equity markets, with the Nikkei 225 down 0.84%, the Topix slipping 0.42% and South Korea’s Kospi falling 1.83%. Iran’s response is equally forceful. The Islamic Revolutionary Guard Corps warned that any vessel entering the strait would be deemed a breach of the cease‑fire and dealt with “harshly and decisively,” insisting it has “full control” and threatening a “deadly vortex” for any misstep. Navy chief Shahram Irani dismissed Trump’s threat as “ridiculous and funny,” while state television said Iranian forces are closely monitoring U.S. movements. Foreign Minister Abbas Araghchi lamented “maximalism, shifting goalposts, and blockade” that undermined a near‑final Islamabad memorandum, quoting, “Good will begets good will. Enmity begets enmity.” Parliament speaker Mohammad Bagher Ghalibaf pledged resistance and mocked U.S. gasoline prices, posting a map of Washington‑area pump prices and predicting nostalgia for $4‑$5 gas. U.S. Central Command clarified that the blockade will stop all vessels bound for or from Iran, while traffic to non‑Iranian ports will continue unhindered. Trump also warned that any ship that has paid an “illegal toll” to Iran will be intercepted on the high seas, and he publicly criticized Pope Leo XIV for urging an end to the conflict. In Lebanon, Israeli airstrikes have killed at least five people, bringing the country’s overall death toll to 2,055. Hezbollah retaliated with a rocket barrage aimed at northern Israeli towns, citing violations of a cease‑fire. The United Nations Interim Force in Lebanon (UNIFIL) reported that an Israeli tank rammed peace‑keeping vehicles twice in the south. Israel’s Prime Minister Benjamin Netanyahu visited troops on the Lebanese border, claiming that Hezbollah’s invasion threat has been neutralized, though he acknowledged that hostilities continue within the security zone. On the energy front, shipping through the Hormuz corridor has “immediately halted,” according to Lloyd’s List, with several vessels turning back after the blockade announcement, further tightening global oil supplies.

The United States military confirmed that, beginning at 10 a.m. Eastern Time (14:00 GMT) on April 13, all maritime traffic entering or leaving Iranian ports will be blocked. The directive, issued by U.S. Central Command (CENTCOM), targets vessels of every nation operating in the Gulf and the Gulf of Oman, but explicitly excludes ships merely transiting the Strait of Hormuz to non‑Iranian ports, marking a narrower scope than former President Donald Trump’s broader strait‑wide threat. This decisive action follows the abrupt end of marathon peace talks in Islamabad, where negotiators failed to secure a memorandum of understanding with Tehran. The stalemate has revived fears of renewed hostilities, prompting the U.S. to leverage maritime pressure as a bargaining chip. Financial markets reacted sharply: U.S. crude oil prices surged 8 % to $104.24 per barrel, while the benchmark Brent crude rose 7 % to $102.29. The spikes reflect investor anxiety over potential disruptions to the flow of oil and liquefied natural gas that currently passes through the Strait of Hormuz, a chokepoint responsible for roughly one‑fifth of global energy shipments. Since the February 28 launch of a joint U.S.–Israel operation against Iran, the strait’s traffic has dwindled to a trickle. Iran continues to navigate its own vessels and has allowed limited passage for foreign ships, while discussing a post‑conflict toll system for the waterway. In response to the blockade threat, Iran’s Islamic Revolutionary Guard Corps warned that any U.S. warship attempting to enforce the measure would breach the existing U.S.–Iran ceasefire—set to expire on April 22—and would be "dealt with severely." Iranian Foreign Minister Abbas Araghchi blamed the United States for the diplomatic failure, accusing U.S. negotiators of "shifting the goalposts" when a deal was "just inches away." Academic commentary echoed regional concerns. Zohreh Kharazmi, an associate professor at the University of Tehran, asserted that the United States "is not in a position to dictate" Iranian maritime movements and warned that a prolonged standoff would quickly reveal which side—"the resilience of the Islamic Republic or the resilience of global markets"—would suffer first. While the blockade targets Iranian ports, CENTCOM emphasized that it will not impede freedom of navigation for vessels merely passing through the Strait of Hormuz, a subtle but significant concession aimed at avoiding a full‑scale maritime confrontation.

U.S. President Donald Trump launched a scathing attack on Pope Leo XIV on Sunday night, branding the pontiff “weak on crime” and “terrible for foreign policy.” The criticism was posted on Trump’s Truth Social account, where he asserted he does not want a Pope who “criticises the President of the United States.” The outburst appears to be a direct response to recent statements by Pope Leo that condemned the United States’ involvement in the Israel‑Iran conflict. Last week, the Pope issued a rare rebuke of Trump’s threat to eradicate Iranian civilisation, calling the threat “truly unacceptable.” On Sunday, he further urged world leaders to halt ongoing bloodshed, describing the war‑driving mindset as a “delusion of omnipotence.” Trump’s post also referenced the Pope’s earlier questioning of the administration’s hard‑line immigration stance, noting the pontiff’s remark that such policies might not be “pro‑life.” In his response, Trump demanded that Leo “use common sense,” stop “catering to the radical left,” and focus on being a “great Pope, not a politician.” Adding a personal jab, Trump claimed credit for the Vatican’s selection of the first U.S.-born Pope, suggesting the election was intended to curry favour with the White House. “If I wasn’t in the White House, Leo wouldn’t be in the Vatican,” he wrote, before reiterating that he is “not a big fan” of the pontiff, accusing him of “liking crime” and labeling him “very liberal.” The tension echoes past friction between Trump and the Vatican, notably with Pope Francis, who had previously criticized the president’s immigration proposals and questioned his Christian credentials. Despite the diplomatic spat, Pope Leo is scheduled to commence an 11‑day African tour on Monday, beginning with a historic visit to Muslim‑majority Algeria.

The ongoing conflict between the US and Iran has taken a turn for the worse, with President Trump's decision to escalate rather than negotiate turning this into a global problem. Europe, which had initially adopted a stance of non-involvement, is now facing the consequences of Trump's actions. The US naval blockade of Iran aims to prevent the country from shipping oil to market unless it allows free passage through the Strait of Hormuz. However, this move has caused oil prices to rise and stocks to fall, with the global economy feeling the pinch. The International Monetary Fund (IMF) meeting in Washington has turned into a crisis summit, with global growth forecasts being revised down due to the expected prolonged energy shock. The conflict has also raised concerns about shortages of essential goods such as medicines, fertilizers, and helium, which could have far-reaching consequences for the global economy. The article suggests that Trump's threats to stop tankers reaching Iranian ports and seize any ship paying Iran a toll for safe passage risk spiraling the war out of control. In this context, former UK Prime Minister Boris Johnson's suggestion that Europe should help the US get out of the mess it has created has some merit. The article argues that Europe needs to find a way to help Trump retreat without losing face, and that diplomacy and negotiation are crucial to resolving the crisis. The article concludes that Trump's war aims are unpredictable and that the US needs NATO's diplomats and ideas to resolve the crisis, rather than just brute force. Europe must find a way to work with the US to end the conflict and prevent further economic damage.

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.
