The Diplomatic Row Poland's president, Karol Nawrocki, has proposed stripping Ukrainian President Volodymyr Zelenskyy of Poland's top honour, the Order of the White Eagle, following Zelenskyy's decree naming a military special forces unit 'Heroes of the UPA', after the Ukrainian Insurgent Army (UPA). The Controversy Surrounding UPA The UPA is regarded by some Ukrainian nationalists as heroes for their resistance against the Soviet Union and Nazi Germany. However, UPA fighters were also involved in the Volhynia massacres in western Ukraine from 1943 to 1945, resulting in the deaths of around 100,000 Poles. The Polish Reaction Polish President Karol Nawrocki expressed outrage and proposed the withdrawal of the Order of the White Eagle from President Zelenskyy. The Chapter of the Order of the White Eagle will meet on June 8 to discuss the matter. Polish Prime Minister Donald Tusk stated that Zelenskyy's move 'wounds our historical sensitivity' and is 'worrying from the point of view of our relations'. The Impact on Relations Poland has been a major ally to Kyiv since Russia invaded Ukraine in February 2022. However, the recent developments have strained relations between the two countries. Polish Nobel Peace Prize-winner Lech Walesa announced that he had stopped wearing a Ukrainian flag pin, stating that Zelenskyy had insulted him and all their massacred compatriots by honouring the UPA. The Future Outlook The diplomatic row between Poland and Ukraine may have implications for the ongoing war in Ukraine and the support provided by Poland to Kyiv. The situation highlights the complexities of historical narratives and their impact on contemporary international relations.

A Note on Chess and Professionals Back in the 1950s most top English players were amateurs, often civil servants or teachers, who competed in tournaments during their vacations. After the 1970s Fischer boom and English successes brought an influx of sponsors, chess professionals could earn a decent living, but the tide turned again during the 1990s. The breakup of the Soviet Union brought harder international competition, while Nigel Short’s world title defeat and the move to screen rather than print marketing drove sponsors away. A New Grandmaster: Harry Grieve Harry Grieve became England’s latest grandmaster on Tuesday when the 25-year-old, who was British champion in 2022 and helped CSC/Kingston finish second in this season’s UK 4NCL League, won first prize in Budapest with a 7/9 total.

The Genesis of a Masterpiece This week we mark two extraordinary centenaries. Sir David Attenborough's, of course, but only four days after the birth of the bona fide national treasure, Dmitri Shostakovich's First Symphony also first saw the light of day – premiered in Leningrad on 12 May 1926. The 19-year-old's composition was played by the Leningrad Philharmonic, conducted by Nicolai Malko. The Revolutionary Sound The symphony's four-movement structure is just about the only conventional feature it has. The teenage Shostakovich had imbibed all the lessons he could about what orchestral music should sound like and how it should behave, and was bold enough to subvert all those ideas and send them up. There is no forelock-tugging to earlier generations of Russian symphonists and orchestral pioneers; instead, Shostakovich's First resounds with a self-confidence that's both optimistic and deliciously sardonic. A Circus of Sound From the distorted trumpet call that opens the work – a fanfare that thumbs its nose at your expectations of how a symphony should start; not an affirmative flourish, but a snakingly dissonant question mark – Shostakovich sets out on a first movement that's like a circus: a cavalcade of characters who take the stage and exit, more often than not pursued by a cartoon bear, clown or bassoon. The momentum that Shostakovich generates from the way he juxtaposes ideas – cutting from one to the other as if the symphony were a reel of film – continues deliriously in the second movement. Here, a piano part is added to the orchestral texture, and that's where one of the secrets of this music's compositional energy is revealed. As a teenager, Shostakovich played the piano for Soviet silent cinema screenings, and in the symphony's piano solos, he turns his work into a knockabout farce that Buster Keaton would be proud of. A Masterpiece of Unbridled Creativity The movement builds to a climax that is both terrifying – a sudden fanfare that consumes the whole orchestra – and bathetic, in the form of the solo piano's chords, as if the pianist couldn't keep up with the music's pace. There is no hint anywhere in this piece of the bombast and poster-paint ideology of Shostakovich's later symphonies, but there is real feeling here, hinted at in that climax of the scherzo, as the cartoon suddenly shudders into real life. The slow movement that comes next is one of the most unironically passionate that Shostakovich ever wrote, as a solo oboe and solo cello inspire the whole orchestra to a melodic outpouring that feels more Shakespearean drama than circus hijinks. A Legacy of Creative Freedom The final movement somehow brings all of these worlds together, and the symphony ends in a torrent of irresistible energy, a culmination of pure sentiment as well as sheer excitement. This is, surely, the most creatively confident First Symphony by any teenager in musical history (and there is plenty of competition, from Mendelssohn to Knussen, from Rihm to Schubert). It announces a world of possibility in which musical conventions are gleefully turned upside down in a frenzy of modernist creativity that's both funny and profound. It's the sound of a unique symphonic avant garde that might have heralded an era of unfettered creative freedom for Shostakovich and generations of composers. A What-If of History Instead, these are the sounds of what might have been, for Shostakovich and for Russia. In Shostakovich's later symphonies, especially from the mid-1930s onwards, you hear the chilling of that freedom and the daily terror of living in Stalin's Soviet Union. The confidence and joy in his own brilliance that you hear in every page of the First Symphony is a miracle that Shostakovich never quite repeated and which is still strikingly new, a century on.

Visual Journey Through Soviet Scientific HeritageThe Guardian released a curated collection of photographs that traverse the former USSR, highlighting Soviet Union landmarks that once celebrated breakthroughs in physics, aerospace, and medicine. The series captures iconic sites such as the Vostok rocket monument outside Moscow, the abandoned Institute of Atomic Physics in Dubna, and the towering Cosmonaut Alley in Baikonur. Scope and Scale of the Photo ProjectOver 30 locations photographed across Russia, Kazakhstan, and UkraineMore than 150 high‑resolution images released onlineCollaboration with local historians and the Russian Academy of Sciences Preservation Numbers Reveal a Strained EffortRecent government reports indicate that only 42% of Soviet scientific monuments receive regular maintenance, with an annual budget of roughly $12 million allocated for restoration. Visitor counts at major sites have risen 15% year‑over‑year, suggesting growing public interest. Why These Symbols Matter for Today’s Science LandscapeThe monuments serve as tangible reminders of the USSR’s rapid advancements during the Cold War, influencing contemporary Russian pride in space exploration and nuclear research. Their presence fuels debates over heritage versus propaganda, especially as Roscosmos seeks to leverage historic imagery for new launch campaigns. Looking Ahead: Preservation, Tourism, and Cultural Re‑engagementExperts predict increased funding for site restoration as heritage tourism expands, potentially adding $30 million to regional economies by 2030. Moreover, the photo series may inspire educational programs that reconnect younger generations with the scientific legacy of the Soviet era.

The Doomsday Clock: A Symbol of Humanity's Existential Threats The Earth is facing unprecedented dangers, from rising temperatures and raging conflicts to the infiltration of AI in critical decision-making processes. The Doomsday Clock, maintained by the Bulletin of the Atomic Scientists, serves as a stark reminder of these threats, currently set at 85 seconds to midnight. The Origins of the Doomsday Clock Established in 1947 by a group of Manhattan Project scientists, the Doomsday Clock was designed to symbolize the urgency of the nuclear age. The first setting was seven minutes to midnight, chosen for its aesthetic appeal. Since then, the clock has been adjusted numerous times in response to global events. Key Milestones in the Clock's History 1947: The first clock setting at seven minutes to midnight. 1949: Moved to three minutes to midnight after the Soviet Union's first nuclear test. 1953: Set to two minutes to midnight following the development of the hydrogen bomb. 2023: Set to 90 seconds to midnight, the closest to apocalypse in its history. The Current State of Global Threats According to Alexandra Bell, CEO of the Bulletin of the Atomic Scientists, the world is sleepwalking into increasing dangers. The intertwining of climate change, nuclear proliferation, and AI integration into military strategies has created a perfect storm of risks. Bell emphasizes the need for leadership and diplomatic efforts to mitigate these threats. The Future of the Doomsday Clock The Doomsday Clock is more than a symbol; it's a call to action. Its setting is determined annually by the Bulletin's science and security board, comprising leading scientists, academics, and diplomats. The clock's message is clear: humanity must act collectively to prevent its own destruction.

Returning Heroes: Liquidators Revisit Chernobyl After Four DecadesOn April 26, 2026, a group of former “liquidators” from Ukraine’s Poltava region stepped onto the abandoned streets of Chernobyl for a day‑long pilgrimage. Their visit marks the 40th anniversary of the explosion that devastated reactor four and serves as a poignant reminder of the personal sacrifices made to contain the world’s worst civilian nuclear accident.Scale of the Cleanup: Numbers Behind the 600,000‑Strong Liquidator Force~600,000 personnel mobilised across the Soviet Union between 1986‑1990.Roles ranged from helicopter pilots dumping sand, clay and lead to miners burying contaminated machinery.Cleanup operations continued for more than 10 days of core fire, followed by years of decontamination work.Environmental and Human Legacy: How the Disaster Shapes Ukraine’s Landscape TodayThe exclusion zone now spans thousands of square kilometres, covering parts of Ukraine, Belarus and Russia. While the nearby city of Pripyat remains a ghost town, nature has reclaimed much of the area, with rare species such as the endangered Przewalski’s horse roaming freely. The human toll includes lingering health issues among survivors and a collective memory that continues to influence Ukrainian society.Future of the Exclusion Zone: Tourism, Conservation, and Security OutlookSince Russia’s invasion in 2022, the zone has been closed to tourists, prompting debates over its future use. Experts argue for a balanced approach that leverages controlled tourism to fund conservation while maintaining strict safety protocols. The return of the liquidators may accelerate policy discussions on how to preserve the site’s historical significance and ecological recovery.

The New Lunar RaceThe world recently watched as NASA sent four astronauts around the moon, marking the first crewed mission to the lunar vicinity since 1972. But the symbolic flyby is merely the opening act in a new space race between the United States and China. Both nations are planning to build the first inhabited lunar bases in history—settlements on another celestial body—while searching for rare resources and testing technology for future crewed missions to Mars.Budget and Political ChallengesWhile NASA possesses institutional knowledge from its Apollo program, it faces significant constraints. The space agency is attempting to return to the moon with just a fraction of the national budget it had in the 1960s. Additionally, NASA is vulnerable to changes in government every four years, making it difficult to maintain consistency in decade-long plans. This political instability contrasts sharply with China's approach, where rocket engineers in a one-party state can execute long-term strategies without interruption.China's Strategic ApproachChina's National Space Administration (CNSA) has demonstrated remarkable consistency in meeting its timeline. When they set a date, they tend to hit it. Unlike the US, China has never lost interest in space exploration. Over the past 25 years, China's space program has accelerated dramatically, partnering with both the military and local businesses. While China has never sent taikonauts beyond low Earth orbit, it has already established its own space station and achieved significant milestones, including becoming the first nation to retrieve samples from the lunar far side with its Chang'e-6 probe in 2024.The Private Space RaceTo move ahead at speed, NASA has outsourced critical mission components to private firms, including billionaire-led ventures aiming to capitalize on the burgeoning space economy. Elon Musk's SpaceX and Jeff Bezos's Blue Origin are both racing to design and build lunar landers in time for test flights next year. However, neither lander is complete, raising questions over NASA's ambitious 2028 moon-landing timeline. In contrast, China is developing its own nine-meter lunar lander called Lanyue ("embracing the moon") and a new spacesuit called Wangyu ("gazing into the cosmos") designed for greater flexibility on the rugged lunar terrain.Marathon, Not a SprintUnlike the 1960s race to the moon between the Soviet Union and the US, the 21st-century competition is shaping up to be more like a marathon, with a gargantuan effort to launch multiple missions over many years. As astrophysicist Scott Manley explains, "It doesn't matter who gets to the moon next. It matters who gets to the moon the next 10 times. The nation that keeps going is going to be the one that actually starts to win; starts to actually claim space."Future Lunar PresenceWith space governance being an area with opaque legal consensus, the first country to establish a sustained presence on the resource-rich lunar surface will likely have a head start in defining the rules. The symbolic value of the first return crewed mission remains significant for domestic prestige and international power projection. NASA Administrator Jared Isaacman acknowledges the tight competition, noting that "the difference between winning and losing will be measured in months not years." While NASA plans to land in 2028 (possibly delayed) and Beijing by 2030 (potentially sooner), the long-term advantage may belong to the nation that demonstrates sustained commitment to lunar exploration and development.

President Donald Trump has launched a scathing attack on NATO, expressing disappointment with the alliance's reluctance to support the US in its conflict with Iran. In a post on his TruthSocial platform, Trump wrote in capital letters: "NATO wasn't there when we needed them, and they won't be there if we need them again".The remarks came after a two-hour meeting with NATO's Secretary-General, Mark Rutte, at the White House. The meeting took place a day after the US and Iran agreed to a ceasefire. Trump's comments have raised concerns about the future of the transatlantic alliance, which he has repeatedly called a "paper tiger".Rutte, known as the "Trump whisperer" for his ability to maintain a productive relationship with the US president, said that Trump was "clearly disappointed with many NATO allies". However, Rutte also pushed back against some of Trump's broader criticism, highlighting the contributions of many European nations to NATO.In addition to his criticism of NATO, Trump also appeared to revive his threat to seize Greenland from Denmark, a move that had previously roiled the alliance. "Remember Greenland, that big, poorly run, piece of ice!!!" he wrote.The Wall Street Journal reported that Trump was considering punishing some NATO members he believed were unhelpful during the conflict by moving US troops out of their countries. However, Rutte declined to comment directly on the report.NATO, formed in 1949 to counter the Soviet Union, has been the cornerstone of Western security. The alliance has only activated its mutual defence clause on one occasion, following the September 2001 attacks on the World Trade Center in the US.
