Lead: A Milestone Reflection on Climate ActionIn its 250th edition, the Guardian's Down to Earth newsletter pauses to assess how the world's fight against climate change has unfolded since the high‑water mark of Cop26 in Glasgow, 2021.Looking Back: Cop26’s Promise and the Five‑Year Journey2021‑2022: Nations pledged to limit warming to 1.5°C, set net‑zero targets and pledged to phase out coal.2022‑2023: The Russian invasion of Ukraine and the Iran‑oil conflict drove crude prices above $100 /barrel, exposing fossil‑fuel vulnerabilities.2024‑2025: Populist governments rolled back environmental regulations, while renewable technology became cheaper and more widespread.Numbers That Matter: Public Awareness and Emissions GapsThe “Covering Climate Now” survey found that 80‑89 % of the global public recognise the climate threat and demand government action.Current national plans still point to a projected warming of about 2.8 °C, well above the agreed target.Renewable energy costs have fallen by roughly 70 % since 2020, making clean power “cheap, widely available and overwhelmingly popular.”Why the Momentum Slowed: Geopolitics, Economics and PopulismWar‑driven spikes in oil prices, the re‑election of climate‑skeptical leaders and the rise of populist rhetoric have eroded the optimism that surrounded Cop26, pushing many countries to backtrack on commitments.What Lies Ahead: Hopeful Trends and Persistent ChallengesDespite setbacks, advances in clean‑tech, growing public pressure and emerging green‑economy initiatives suggest a pathway forward, but the intertwined climate‑biodiversity‑economy crises demand coordinated global action.

The Global Initiative to Reproductive HealthIn a landmark development for women's healthcare, an unprecedented global collaborative effort has resulted in the official renaming of Polycystic Ovary Syndrome to Polyendocrine Metabolic Ovarian Syndrome (PMOS). This significant shift in medical terminology aims to address long-standing concerns about the condition's name and bring fresh hope to the millions of women affected worldwide.The Evolution of PCOS TerminologyThe term 'Polycystic Ovarian Syndrome' has been used for decades to describe this common endocrine disorder affecting women of reproductive age. However, medical professionals and patient advocates have increasingly highlighted limitations in the current name, which focuses primarily on ovarian cysts while overlooking the broader metabolic and endocrine aspects of the condition.The new name, 'Polyendocrine Metabolic Ovarian Syndrome,' more accurately reflects the complex, systemic nature of the disorder, which involves multiple hormonal systems and metabolic processes beyond just ovarian characteristics.Understanding the Scope of PCOS ImpactPCOS/PMOS affects an estimated one in ten women of reproductive age globally, making it one of the most common endocrine disorders. The condition is associated with a range of symptoms including irregular menstrual cycles, hormonal imbalances, insulin resistance, and metabolic issues, which can significantly impact quality of life and long-term health outcomes.The renaming initiative represents a significant step forward in recognizing the complexity of this condition and improving both medical understanding and patient experiences.Shifting Medical Perceptions Through NamingThe terminology shift is expected to have profound implications for how healthcare providers approach diagnosis, treatment, and patient education. By emphasizing the metabolic and endocrine components of the condition, the new name encourages a more holistic approach to care that addresses the full spectrum of symptoms and health implications.For patients, the change represents validation of their experiences beyond reproductive concerns and recognition of the condition's systemic impact on overall health and wellbeing.The Future of Women's Metabolic HealthAs medical communities worldwide adopt the new terminology, researchers anticipate increased funding and focus on understanding the metabolic aspects of PMOS, potentially leading to more targeted treatments and improved outcomes for patients.This renaming effort underscores the importance of patient-centered approaches in medical terminology and sets a precedent for how conditions affecting women's health are described and understood in the future.

The Growing Fear Among Muslims In Meerut, India, a group of Muslim men are huddled inside a small mosque, discussing the arrangements for Eid al-Adha prayers. The conversation is not about sacrificial animals or charity, but about the pressing issue of where and how they will offer their prayers on Thursday. Restrictions on Public Prayers For more than a decade, right-wing Hindu groups have been protesting against Muslims offering public prayers on Fridays and festivals, citing traffic and security concerns. These groups, and even politicians from Modi's Bharatiya Janata Party (BJP), have disrupted namaz on roads, in parks, or on vacant plots of land. The Impact on Muslim Communities The restrictions on Eid prayers are creating an atmosphere in which even routine religious gatherings are increasingly treated as security concerns. Mosque committees are quietly recalibrating Eid arrangements, reducing the size of congregations, and asking worshippers to arrive in smaller groups or disperse quickly after prayers. The Psychological Impact For many Muslims, the psychological impact of such restrictions and targeting extends beyond the prayer ground. There is a fear of humiliation, and parents tell young people to avoid standing outside mosques because they don't want trouble. Selective Enforcement of Rules While the government frames the restrictive measures around Muslim festivals as necessary for traffic management and public order, it has also facilitated large Hindu religious processions and celebrations with traffic diversions, police protection, and public infrastructural support. Critics say the contrast with the crackdown on namaz deepens perception among Muslims of a selective enforcement of rules.

Scientists have unveiled a new giant sauropod from Thailand, naming it Nagatitan chaiyaphumensis. The discovery, detailed in Scientific Reports, positions the species as the largest known dinosaur from Southeast Asia and offers fresh clues about the region’s prehistoric environment.Discovery of Nagatitan chaiyaphumensis in Northeast ThailandThe fossil remains were first spotted by local residents a decade ago in the Chaiyaphum province, but systematic excavation only concluded in 2024. The specimen, recovered from one of the youngest Thai rock formations, displayed unique skeletal features that warranted classification as a new species within the sauropod lineage.Size and Weight Estimates Put Nagatitan Among the Largest SauropodsMeasurements indicate the herbivore stretched 27 metres (89 feet) long and weighed about 27 tonnes, comparable to the mass of nine adult elephants. Researchers note it likely outweighed the famous Diplodocus cast “Dippy” at the Natural History Museum by at least 10 tonnes. The animal is dated to have roamed the area between 100 and 120 million years ago, during the mid‑Cretaceous.Implications for Southeast Asian Paleontology and Regional HeritageAs the biggest dinosaur ever found in Southeast Asia, Nagatitan expands the known geographic range of late‑surviving sauropods, which were thought to have largely disappeared from the region when it became a shallow sea in the Cretaceous. The find underscores Thailand’s growing importance as a paleontological hotspot and adds to the modest list of 14 named Thai dinosaurs.Future Research Directions and Tourist OpportunitiesLead author Thitiwoot Sethapanichsakul—a University College London PhD student—suggests further fieldwork could clarify the dinosaur’s feeding habits, which likely involved bulk browsing of conifers and seed ferns. A life‑size reconstruction now stands at Bangkok’s Thainosaur Museum, hinting at increased scientific tourism and educational outreach in the region.
