Nelson Mandela once claimed sport could spark hope where despair prevailed – a sentiment that now feels overly optimistic as climate change threatens every arena, from football pitches to alpine slopes.Extreme weather events are already cancelling competitions and rendering venues unplayable through floods, wildfires and storms. Rising heat and air‑pollution expose athletes to heat‑related illnesses, asthma and cardiovascular strain, while also increasing injury risk and diminishing performance for officials and spectators alike.Countries most vulnerable to climate impacts face the harshest sporting challenges. As Barbados Prime Minister Mia Mottley warned, athletes must compete on the conditions that exist, not on idealised pitches, while wealthier nations and governing bodies often look the other way.Historian David Goldblatt estimates sport’s carbon footprint rivals that of a small‑ to medium‑sized nation – roughly the emissions of Cuba to Poland. Yet the industry continues to chase growth, attracting sponsorship from fossil‑fuel giants and even entities reminiscent of the tobacco era.A 2024 “Dirty Money” report by the New Weather Institute revealed that state‑owned and private fossil‑fuel companies have poured at least $5.6 billion (£4.2 billion) into global sport across 205 active deals. The recent Milan‑Cortina Winter Olympics relied on oil major Eni to fund artificial snow, while the upcoming men’s football World Cup – labelled the “most polluting ever” by Scientists for Global Responsibility – will be plastered with ads from Aramco, the world’s largest corporate greenhouse‑gas emitter, with emissions projected to be 92 % higher than typical tournaments between 2010‑2022.Fans and grassroots organisations are pushing back. Groups such as Surfers Against Sewage, Fossil Free Football, FrontRunners and Protect Our Winters are mobilising, while clubs like Forest Green Rovers and athletes such as Australian cricket captain Pat Cummins are publicly denouncing fossil‑fuel ties.Alternative sponsorships are emerging: Northern Rail backs the Rugby Super League, Metrobank partners with cricket, and Oxford United’s limited‑edition shirt celebrates John Ruskin’s “Study of a Wild Rose,” linking sport to environmental heritage.“The Hotspot” aims to surface the most compelling stories, analyse data, and chart a path forward for sport in a warming world.

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.

The Evolution of Enterprise AutonomyMicrosoft is quietly pivoting from reactive AI assistants to proactive, autonomous agents within its ecosystem. The tech giant is currently testing a new feature set for Microsoft 365 Copilot that mimics the capabilities of the open-source OpenClaw agent. This move signals a strategic shift toward "always-on" intelligence that can execute multistep tasks autonomously, rather than merely responding to user prompts. Microsoft's "Always-On" Copilot StrategyThe core innovation of this potential new agent is its ability to function continuously. Unlike previous iterations that required active user engagement, this tool would be designed to take actions at any time, effectively acting as a persistent digital assistant. Microsoft has confirmed to The Information that the focus is on enterprise customers, specifically addressing the security concerns that have historically plagued open-source alternatives. Autonomous Execution: Capable of handling multistep workflows without constant supervision. Enterprise Focus: Prioritizing security controls over the flexibility of open-source tools. Integration: Built directly into the existing Microsoft 365 ecosystem. Cloud vs. Local: The Hardware ImplicationWhile the source material suggests a comparison with OpenClaw—which runs locally on hardware like the Mac Mini—Microsoft has not confirmed if this new agent will be local or cloud-based. However, the trend is clear. The company previously launched Copilot Cowork (powered by Anthropic's Claude) and Copilot Tasks, both of which operate in the cloud. The potential shift to a local execution model would explain the recent surge in Mac Mini sales, as users seek hardware capable of running these resource-intensive, privacy-focused agents. Why This Matters for Enterprise SecurityThe primary driver for this development is the "trust gap" in enterprise AI. Open-source agents like OpenClaw offer powerful automation but carry significant security risks. By creating a proprietary version, Microsoft aims to offer the autonomy of open-source tools with the governance of a major corporation. This aligns with Microsoft's broader strategy of anchoring AI experiences in security, governance, and trust, reducing the friction of daily operations for enterprise workers. Expectations for Microsoft Build 2026Industry analysts predict that this new agent—or an upgraded version of existing tools—will be a centerpiece of the upcoming Microsoft Build conference in June. While the company remains tight-lipped about the specifics, the spokesperson's confirmation that they are "experimenting" with broader orchestration and autonomy suggests a major reveal is imminent. This development could redefine how businesses interact with their software stack, moving from a tool-based model to an agent-based model.

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 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.

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.
