SUMMARY:DNA Day 2026
DESCRIPTION:DNA Day is a United States holiday celebrated on April 25\, it commemorates the day in 1953 when James Watson\, Francis Crick\, Maurice Wilkins\, Rosalind Franklin and colleagues published papers in the journal Nature on the structure of DNA. \nFurthermore\, in early April 2003 it was declared that the Human Genome Project was very close to complete\, and “the remaining tiny gaps were considered too costly to fill.” In the United States\, DNA Day was first celebrated on April 25\, 2003\, by proclamation of both the Senate and the House of Representatives. However\, they only declared a one-time celebration\, not an annual holiday. Every year from 2003 onward\, annual DNA Day celebrations have been organized by the National Human Genome Research Institute (NHGRI)\, starting as early as April 23 in 2010\, April 15 in 2011 and April 20 in 2012. April 25 has since been declared “International DNA Day” and “World DNA Day” by several groups. Genealogical DNA testing companies and genetic genealogy publishers run annual sales around DNA Day\, seeking interest from the public and promoting their services. \nLinks:\nDNA Day \nESHG DNA Day Essay & Video Contest

SUMMARY:Day in Memory of the Victims of Earthquakes 2026
DESCRIPTION:In April 2025\, the United Nations General Assembly designated 29 April as the International Day in Memory of the Victims of Earthquakes inviting all Member States\, organizations of the United Nations system and other relevant international organizations to collaborate on the commemoration. \nIn doing so\, the General Assembly reaffirmed its commitment to the 2030 Agenda for Sustainable Development and recalled the Sendai Framework for Disaster Risk Reduction 2015–2030\, recognizing that disasters continue to undermine sustainable development. These commitments underscore that understanding disaster risk\, strengthening prevention and mitigation\, and improving preparedness and effective response are essential to protecting lives and achieving the Sustainable Development Goals by 2030. Earthquakes are among the deadliest natural hazards\, often striking without warning and causing devastating loss of life and long lasting social\, economic\, and psychological harm. Recent earthquakes in countries such as Myanmar and Afghanistan are stark reminders of how these events can destroy infrastructure\, displace entire communities\, and affect generations long after the ground stops shaking. Their impact is severe and measurable. Since 1900\, there have been at least 12 major earthquakes\, each of which killed more than 50\,000 people. Earthquakes also have substantial economic consequences\, accounting for more than a quarter of global disaster losses and causing trillions of dollars in damage over recent decades. Beyond direct destruction\, they can trigger fires\, tsunamis\, and landslides\, compounding damage across housing\, health\, education\, and livelihoods. Earthquake risk is driven by factors such as rapid urbanization in seismic areas\, weak or ageing infrastructure\, poverty\, inequality\, and poor enforcement of building codes—making risk informed development and resilient infrastructure essential. In acknowledgement of the grave consequences of these disasters\, the United Nations has established the International Day in Memory of the Victims of Earthquakes\, observed annually on 29 April\, and tasked the United Nations Office for Disaster Risk Reduction (UNDRR) with facilitating its observance. The Day provides a moment to remember those lost and renew commitment to prevention\, preparedness\, and building back better\, in line with the priorities of the Sendai Framework for Disaster Risk Reduction. \nLinks:\nWhen the ground shakes: Remembering victims and reducing future loss

SUMMARY:Wat zegt een keurmerk nog? - publicatie / Dierenleed verdient geen keurmerk! - petitie
DESCRIPTION:De keurmerken ASC en GGN prijken op bijna alle zalmproducten in onze supermarkten\, ze beloven consumenten verantwoorde visteelt\, schoon water en eerlijk toezicht. \nMaar officiële inspectierapporten en het onderzoek ‘Wat zegt een keurmerk nog?‘ van foodwatch tonen een heel ander beeld: op gecertificeerde kwekerijen sterven vissen bij miljoenen\, worden hygiëneregels aan de laars gelapt en blijven zelfs grove overtredingen zonder gevolgen. In Noorwegen (’s werelds grootste zalmleverancier) stierf in 2023 elke zesde zalm vóór de slacht. De hoogste sterfte die het Noorse Veterinaire Instituut ooit mat. Toch dragen zo’n 42 procent van de Noorse kwekerijen nog steeds het ASC-keurmerk\, en bij GGN loopt dat zelfs op tot 90 procent. Het systeem faalt. Inspecties worden weken van tevoren aangekondigd; tijd genoeg om problemen te verdoezelen. Dat er dan genoeg tijd is om te “opruimen”\, bewees een kwekerij in Schotland: slechts uren vóór een aangekondigde inspectie door parlementariërs werden er in 2024 tonnen dode vissen afgevoerd. Die kwekerij had geen ASC-certificering\, maar dit incident toont aan dat het aankondigen van inspecties uitnodigt tot verdoezeling van problemen. Meerdere kwekerijen worden als groep gecertificeerd\, waardoor lang niet elke locatie individueel wordt gecontroleerd. En de traceerbaarheid stopt bij het verpakkingsbedrijf: foodwatch kocht diverse ASC- of GGN- gecertificeerde kweekzalmproducten en vroeg de supermarkten naar de herkomstboerderij. Dat lukte maar bij 37\,5% van de gevallen. Supermarkten en consumenten vertrouwen blind op deze keurmerken. Dat vertrouwen is niet gerechtvaardigd. Teken de petitie en stuur een bericht aan ASC en GGN: dit is niet goed genoeg! De eisen: \n\nVolledige traceerbaarheid voor consumenten tot aan de individuele kwekerij\, niet alleen tot het verpakkingsbedrijf.\nOnaangekondigde\, onafhankelijke inspecties en publicatie van alle auditresultaten.\nBindende sterftegrenzen met directe gevolgen: wie de grens overschrijdt\, verliest het keurmerk.\n\nLinks:\nFoodwatch slaat alarm\, maar hoe problematisch is kweekzalm nu echt?

SUMMARY:The “Nuclear Energy Paradox”- Investigating nuclear imaginaries in energy projections - publication
DESCRIPTION:The paper ‘The “Nuclear Energy Paradox”- Investigating nuclear imaginaries in energy projections‘ investigates the “nuclear energy paradox” which shows the recurring divergence between historical projections and actual developments. \nA data compilation of long-term energy projections from international organizations such as the IAEA and the IEA as well as energy system models like GCAM and MESSAGE\, as used in the IPCC\, reveal a recurring pattern of high-growth projections for nuclear power. Decades of high-growth projections for nuclear power from (inter-)national agencies and from academia can be observed. Actual development shows divergence between projections and reality. A recurring pattern of overestimation can be identified\, which we call the “nuclear energy paradox”. The paradox is rooted in nuclear imaginaries like the plutonium economy and/or hopes of mass production of\, e.g.\, SMRs. Recent energy scenarios are still driven by narratives that are based on certain nuclear imaginaries. \nLinks:\nWarum Kernenergie scheitert • Nukleares Paradox & Falsche Prognosen?

SUMMARY:De hoogste bomen vangen minder wind: belastingdruk op inkomens en vermogens - publicatie
DESCRIPTION:De economische verschillen tussen huishoudens nemen toe\, het belastingstelsel dempt deze ontwikkeling niet en draagt soms zelfs bij aan de groeiende verschillen. \nDat komt onder meer doordat verschillende vormen van inkomen en vermogen anders worden belast\, belastingheffing soms langdurig kan worden uitgesteld en er veel ondoelmatige fiscale regelingen zijn. Aanpassingen van het belastingstelsel kunnen bijdragen aan het beperken van verdere groei van economische verschillen en economische verstoringen en zo de welvaart bevorderen. Dat blijkt uit de publicatie ‘De hoogste bomen vangen minder wind: belastingdruk op inkomens en vermogens‘ van het Centraal Planbureau (CPB). Welke mate van ongelijkheid wenselijk of acceptabel is\, is een politieke vraag. Dat geldt ook voor de mate waarin het belastingstelsel een herverdelende werking zou moeten hebben\, maar de meeste mensen zijn van mening dat herverdeling via de belastingen gewenst is. \nLinks:\nDe hoogste bomen vangen minder wind: belastingdruk op inkomens en vermogens

SUMMARY:Satellite quantification of enhanced methane oxidation applied to the stratospheric plume following Hunga Tonga-Hunga Ha’apai eruption - publicatie / publication
DESCRIPTION:Een internationaal onderzoeksteam onder leiding van het KNMI heeft voor het eerst overtuigend aangetoond dat methaan — een belangrijk broeikasgas — in de atmosfeer op een natuurlijke manier kan worden afgebroken door chloor. \nDeze ontdekking werd gedaan dankzij een mengsel van zout en as in de enorme rookpluim van de Hunga Tonga–Hunga Ha’apai-vulkaanuitbarsting van januari 2022\, een van de krachtigste uitbarstingen in recente decennia. De resultaten\, gepubliceerd in het artikel ‘Satellite quantification of enhanced methane oxidation applied to the stratospheric plume following Hunga Tonga-Hunga Ha’apai eruption‘\, zijn gebaseerd op satellietmetingen en bieden nieuwe inzichten in hoe de atmosfeer zichzelf zuivert — en wat dat kan betekenen voor de aanpak van klimaatverandering. \nLinks:\nVulkaan Tonga toont voor het eerst natuurlijke katalytische afbraak van methaan door vulkaanas in de atmosfeer

SUMMARY:David Attenborough 100
DESCRIPTION:David Frederick Attenborough (/ˈæt(ə)nb(ə)rə/; born 8 May 1926) is an English broadcaster\, natural historian\, conservationist\, writer\, producer and narrator. \nHis presenting career began as host of Zoo Quest in 1954\, and has spanned eight decades; it includes the nine documentary series forming The Life Collection\, Natural World\, Wildlife on One\, the Planet Earth franchise\, The Blue Planet and Frozen Planet. He is the only person to have won BAFTA Awards in black-and-white\, colour\, high-definition\, 3D and 4K resolution. Over his life\, he has collected dozens of honorary degrees and awards\, including three Primetime Emmy Awards for Outstanding Narrator and one Daytime Emmy Award for Outstanding Daytime Personality – Non-Daily. Attenborough was a senior manager at the BBC\, working as controller of BBC Two and director of programming for BBC Television in the 1960s and 1970s. While his earlier work focused primarily on the natural world\, his later work has been more vocal in support of environmental causes. He has advocated for restoring planetary biodiversity\, limiting population growth\, switching to renewable energy\, mitigating climate change\, reducing meat consumption and setting aside more areas for natural preservation. On his broadcasting and passion for nature\, NPR stated that Attenborough “roamed the globe and shared his discoveries and enthusiasms with his patented semi-whisper way of narrating”. He is widely considered a national treasure in the UK\, though he does not embrace the term. \nLinks:\nWish Sir David Attenborough a happy 100th birthday

SUMMARY:Centrale Eindexamens voortgezet onderwijs Nederland 2026
DESCRIPTION:Het eindexamen is het afsluitende examen van een studierichting of opleiding. \nIn Nederland wordt daarmee doorgaans bedoeld: het schoolexamen en het centraal examen ter afsluiting van een opleiding (vmbo\, havo\, vwo) aan het voortgezet onderwijs. Voor het voorbereiden van het eindexamen wordt vaak gebruik gemaakt van Examenbundel en sommige leerlingen volgen ook een examentraining. In België bestaat geen dergelijk centraal examen; een eindexamen is er het proefwerk in het laatste jaar van een opleiding. \nLinks:\nExamenrooster 2026 \nEindexamens voortgezet onderwijs \nLAKS Examenklacht

SUMMARY:Deep Arctic Expedition
DESCRIPTION:Voor de eerste keer gaat Greenpeace\, samen met onderzoekers van verschillende universiteiten\, op expeditie naar de diepzee van de Noordpool en zal dit onbekende natuurgebied verkennen om wetenschappelijk bewijs te verzamelen om de diepzee te beschermen. \nDiep onder het ijs van de Noordpool ligt een schat die van ons allemaal is. Het is een plek waar oude sponzen groeien en walvissen samenkomen. Het “Banana Hole” is een bijzonder gebied in de Noordpool. Hier vind je onderwaterbergen en vulkanische warmwaterbronnen die ons alles vertellen over de geschiedenis van onze aarde. Maar dit kwetsbare gebied is in gevaar: mijnbouwbedrijven willen de bodem afgraven voor mineralen. Dit zou de natuur voor altijd vernietigen\, nog voordat we de planten en dieren daar hebben ontdekt. \nLinks:\nOntdek het onbekende Bescherm de diepzee
