The Guardian’s latest science podcast examines the worldwide campaign to wipe out Guinea worm disease, a parasitic infection that could become the second human disease ever eradicated after smallpox. Hosted in 2026, the episode highlights why the disease remains a focal point for public‑health leaders and what its elimination would mean for global health security.Guinea worm, transmitted through contaminated water, has been the target of an intensive eradication effort led by the World Health Organization and partners in endemic regions. The podcast underscores the progress made: cases have plummeted from millions in the 1980s to just a handful today, illustrating the power of coordinated surveillance, safe‑water interventions, and community education.Despite the gains, experts caution that complete eradication is not guaranteed. Residual hotspots in remote villages, logistical challenges in delivering clean water, and the need for sustained funding pose ongoing risks. The discussion stresses that a lapse in commitment could allow the parasite to rebound, undoing decades of progress.Historically, smallpox remains the only disease humanity has fully eradicated, a milestone achieved in 1980 after a global vaccination campaign. The potential success of the Guinea worm program would mark a watershed moment, demonstrating that eradication is feasible beyond vaccine‑preventable illnesses and could inspire similar initiatives for other neglected tropical diseases.Listeners are encouraged to support the effort through the Guardian’s science podcast platform, where additional resources and ways to contribute are provided. As the episode concludes, the hosts reiterate that the fight against Guinea worm is both a test of global solidarity and a template for future disease‑elimination campaigns.

Season ContextManchester City host Arsenal at the Etihad with the title race at a fever pitch. A loss would leave Guardiola three points shy of the league leaders, meaning City would need to win their final match while Arsenal drops points to stay in contention.Guardiola's Contract and FutureCurrent contract runs until summer 2027, signed in November 2024.Guardiola has hinted this could be his “last season”, citing “the problems we had in the last month”.The club’s hierarchy, led by chairman Khaldoon al‑Mubarak, is reportedly seeking clarification ahead of the international break.Historical ComparisonReplacing Pep Guardiola could be as daunting as Manchester United’s search for a successor to Sir Alex Ferguson in 2013. Ferguson’s successor David Moyes was dismissed after just 34 league games, and United have cycled through five more managers since.Strategic ImplicationsCity sit three points behind Arsenal with one game remaining – a win would level the points and force a title decider.Guardiola already holds 16 major honours with City, including a recent Carabao Cup win over Arsenal.Should he depart, the club’s “best‑in‑class structure” under Mubarak would remain, but finding a manager capable of maintaining the elite culture is a significant risk.Beyond the silverware, the legacy of Guardiola’s decade at the Etihad may be measured by how smoothly the club navigates the transition, a test that could define City’s dominance for years to come.

Background and Early Years Bob Mould – former frontman of Hüsker Dü, solo artist after 1988. 1991: Mould writes songs that become Copper Blue while grunge explodes via Nirvana. 1992: Formation of Sugar with bassist David Barbe and drummer Malcolm Travis. Rise of Sugar and *Copper Blue* The debut album Copper Blue blended metallic guitar walls with melodic pop, earning critical plaudits and commercial success unprecedented for an underground act. It reached the UK Top 10 and won NME’s 1992 Album of the Year – a win Mould likens to “winning an Oscar.” This chart position represented a shift from niche indie sales (typically under 50,000 units) to mainstream exposure, roughly a 5‑fold increase in album‑move volume. Impact of Kurt Cobain’s Death In April 1994, while recording their second album at Triclops Studio, Mould learned of Kurt Cobain’s suicide. The shock prompted him to “pull the plug” on the recordings, erasing the tapes and stating there was “nothing worth saving.” This abrupt halt illustrates how the post‑Nirvana cultural landscape forced alternative bands into a new celebrity‑driven paradigm, pressuring them to navigate fame and personal trauma simultaneously. Second Album and Disbandment 1994: Release of the EP Beaster, reaching No 3 in the UK charts despite its dark religious themes. 1995: After a rushed three‑month writing session for File Under: Easy Listening, internal pressures and Barbe’s family commitments lead to Sugar’s dissolution. Reunion and Legacy After three decades of solo work, Mould, Barbe, and Travis reconvened in 2026. The band announced a European and US tour from May to October, adding two new tracks to commemorate the reunion. While Mould remains non‑committal about future recordings, he emphasizes enjoying the live experience—a contrast to the “no‑time‑for‑reflection” era of the early 90s. Key Takeaways Copper Blue transformed Sugar from an underground act to a mainstream chart‑breaker. The death of Kurt Cobain acted as a cultural inflection point, prompting Mould to abandon a nearly finished second album. Three‑decade‑long hiatus underscores the lasting influence of 90s alternative rock on today’s touring circuits. Fans are advised to bring earplugs—the band’s signature “colossal, metallic, thunderous” sound remains as punishingly loud as ever.

Bulgaria is holding its eighth parliamentary election in five years, with polling stations opening at 7am local time (04:00 GMT) and closing at 17:00 GMT. The election is significant as it could bring to power a left-leaning, pro-Russian former President Rumen Radev, just days after voters in Hungary rejected the authoritarian policies and global far-right movement of Viktor Orban.The December protests that brought down the previous conservative-led government drew hundreds of thousands of mainly young people to the streets, calling for an independent judiciary to tackle widespread corruption. Radev, a former air force general, has said he wants to rid the country of its “oligarchic governance model” and backed anticorruption protests late last year.Radev has advocated for renewing ties with Russia and criticised sending military aid to Ukraine. He resigned from the mainly ceremonial presidency in January to launch his bid to lead the government as prime minister. However, his stance has drawn criticism from opponents, who accuse him of being too accommodating towards the Kremlin.Bulgaria, a nation of 6.5 million people, has faced repeated political instability since 2021, with fragmented parliaments producing weak coalition governments. The EU member state has cycled through a succession of administrations since mass anticorruption protests in 2021 ended the conservative rule of longtime leader Boyko Borissov.The opinion polls suggest that Borissov’s pro-European GERB party is expected to finish second, with about 20 percent support, ahead of the liberal PP-DB alliance. Official results are likely to be announced on Monday.

Venice, a city renowned for its rich history and cultural heritage, is facing an unprecedented threat from rising sea levels. The Mose flood defence system, which was launched in 2020, has saved the city from potential flooding 154 times. However, despite its success, the city authorities are already seeking a plan B due to the accelerating sea level rise.The Mose system, which stands for modulo sperimentale elettromeccanico (experimental electromechanic module), was designed to protect Venice from frequent acque alte (high waters) caused by storm surges. The system consists of massive, luridly coloured flood barriers sunk into the seabed at three inlets between the lagoon and the Adriatic. The barriers have been effective in preventing flooding, but their frequent use is damaging the lagoon's ecosystem.Rising sea levels due to the climate crisis mean engineers are forced to raise the flood barriers more frequently, which encourages an excess growth of algae. When the algae die, they decompose, sucking out all the oxygen in the water and killing off fish and other marine flora. The tides create a natural exchange of water and sediment between the Venice lagoon and the Adriatic, but the raised flood barriers block the flow of water, leading to a deterioration of the lagoon's ecosystem.Andrea Rinaldo, the head of the scientific committee of the newly appointed Lagoon Authority, warns that an estimated extra metre of sea level rise by the end of the century represents a 'death knell for the city'. He stresses that immediate action is necessary to prevent the city's destruction. 'You won't have a lagoon. You won't have a city. And all of this could happen in a timeframe that is comparable with the time that we had to design and build the Mose.'The city authorities are exploring alternative solutions, including redirecting Venice's economy away from its reliance on tourism, which is a major threat to the city. Rinaldo plans to put out a global call for ideas from leading thinkers across various disciplines to devise a proposal for the city's future.

Marine expert Richard Land leads a 2026 effort to release more than 15 million juvenile oysters into the North Sea off Orkney, aiming to rebuild historic beds and spark a trophic cascade of climate and ecological benefits.The project, backed by the Green Britain Foundation, the Nature Restoration Fund, Marine Fund Scotland and North Bay Innovations, employs a novel on‑shore rearing technique that cultivates oysters on calcium‑carbonate‑enriched plates before deploying them on long lines at sea.According to Richard Land, the initiative will not only aid fish stocks but also support sea mammals, seabirds and the broader marine environment. He describes the scheme as a blueprint for wider oyster reintroduction across the UK and European waters.Historical oyster beds once covered areas the size of Wales in the North Sea. Over‑exploitation during the Industrial Revolution—Londoners alone ate an estimated 700 million oysters between 1840‑1850—combined with pollution, climate change and habitat removal, led to a “negative cascade” that devastated marine ecosystems.Researchers estimate the new 100‑hectare (247‑acre) reef could sequester up to 76 tonnes of CO₂ annually. Project backer Dale Vince notes that once natural spawning is re‑established, carbon capture could exceed this figure by over 1,000‑fold after about 15 years.Alistair Carmichael, Liberal Democrat MP for Orkney and Shetland, welcomed the plan, highlighting its dual promise of wildlife recovery and carbon sequestration. Philine Zu Ermgassen of the University of Edinburgh stressed that hatchery innovations are essential to produce sufficient local‑genetic stock for successful restoration.By re‑introducing native oysters, the scheme aims to create complex reefs that host scallops, molluscs, algae, seaweeds and numerous invertebrates, thereby revitalising marine biodiversity while contributing to climate mitigation.

The Lead: Tesla's Texas Expansion Tesla is expanding its fully driverless operations, expanding its robotaxi service to Dallas and Houston to join Austin as the third Texas market. Despite the rollout, the fleet size appears significantly smaller than in Austin, and safety metrics remain a critical point of scrutiny following 14 reported crashes in the initial market.The Event Details: Rolling Out in Dallas & Houston Tesla announced the expansion via social media, confirming that "Robotaxi is now rolling out in Dallas & Houston 🤠." The company released a video demonstrating vehicles navigating city streets without human monitors or drivers in the front seat. This move marks a significant step in Tesla's broader strategy to transition from a traditional automaker to a mobility-as-a-service provider, building upon the foundation established in Austin.Fleet Size Disparity: Austin vs. New Markets While the expansion is a strategic milestone, the scale of deployment reveals a stark contrast between markets. Crowdsourced data from the Robotaxi Tracker indicates that while Austin hosts 46 active vehicles, only a single vehicle is currently registered in both Dallas and Houston. This suggests that Tesla is prioritizing infrastructure and regulatory approval in its home state before aggressively scaling the fleet to new territories.Safety Implications and Regulatory Scrutiny The expansion comes at a time when safety remains a major hurdle for autonomous vehicle (AV) companies. A February filing revealed that Tesla's robotaxis in Austin have been involved in 14 crashes since the service launched. As Tesla pushes into major metropolitan areas like Dallas and Houston, regulators are likely to intensify their oversight, potentially demanding higher safety standards or clearer liability frameworks for fully driverless rides.The Future of Fully Autonomous Mobility The Dallas and Houston expansion signals Tesla's intent to dominate the autonomous driving market in the South. However, the disparity in fleet numbers suggests a cautious approach. We can expect Tesla to focus on optimizing its software and safety protocols in these new cities before a wider rollout. Ultimately, the success of this expansion will hinge on whether Tesla can reduce the accident rate in its existing markets to gain public trust and regulatory approval in high-density urban environments.

President Donald Trump signed an executive order on Saturday in the Oval Office, joined by podcaster Joe Rogan, to fast‑track the federal review of psychedelic drugs such as ibogaine, aiming to broaden treatment options for serious mental illness.The ceremony highlighted Rogan’s long‑standing advocacy for ibogaine, a plant‑derived compound used by some veteran groups to address post‑traumatic stress. Rogan recounted texting Trump about the drug, to which the president replied, “Sounds great. Do you want FDA approval? Let’s do it.”Trump framed the order as a lifeline for patients: “Today’s order will ensure that people suffering from debilitating symptoms might finally have a chance to reclaim their lives and lead a happier life.” He added that successful outcomes could have “a tremendous impact.”In a brief moment of levity, Trump joked, “Can I have some, please? I’ll take some.” He quickly refocused, noting he has no time for depression and stays busy instead.The move enjoys rare bipartisan backing, despite ibogaine and other psychedelics remaining classified under the federal government’s most restrictive drug schedule.Health Secretary Robert F. Kennedy Jr. had previously pledged to ease medical access to psychedelics, a stance echoed in the new order, which directs the Department of Health and Human Services to allocate at least $50 million to states developing programs for serious mental‑health conditions.Simultaneously, the FDA is set to issue “national priority” vouchers for three psychedelic candidates. Commissioner Marty Makary said the vouchers will enable rapid approval “if they align with our national priorities.”The agency also plans the first human trials of ibogaine in the United States, overcoming earlier concerns about potential fatal heart effects.Ibogaine’s origins trace back to the Bwiti religious ceremonies in West‑Central Africa, where the plant has been used for centuries in spiritual contexts.Former Navy SEAL Marcus Luttrell, also present at the event, praised ibogaine, stating, “It absolutely changed my life for the better.”Rogan’s endorsement and the executive order have added a new dimension to Trump’s 2024 campaign narrative, even as he has publicly questioned the administration’s stance on the war with Iran.
