SUMMARY:Exploring Everyday Microplastic Exposures - publication
DESCRIPTION:The report ‘Exploring Everyday Microplastic Exposures‘ reveals shocking scale of hidden global microplastic exposure. \nThe report highlights the vast scale of microplastic exposure in daily life in what experts are calling a “microplastic storm” from overlooked and emerging sources. Funded by Plastic Soup Foundation and The Flotilla Foundation\, ‘Exploring Everyday Microplastic Exposures’\, the first-of-its-kind report draws on over 350 peer-reviewed studies and concludes that human exposure is continuous and global. The findings lay bare an exposure crisis through mapping microplastic release across five categories of everyday life: outdoor sources\, indoor environments\, children’s products\, healthcare and personal care\, and food and drink. By highlighting a continuous flow of particles generated from overlooked and emerging sources the report reframes the plastics crisis as a systemic exposure issue embedded across modern society. Among the report’s most striking findings is evidence that emerging climate interventions could make microplastic exposure significantly worse. For example\, stratospheric aerosol injection – a form of solar geoengineering being advanced by countries including the United Kingdom and United States – involves dispersing vast quantities of particles high into the atmosphere. Multiple patents already exist describing the release of particles including micro sized polymeric particles at altitudes of up to 20 km in the atmosphere\, creating a potentially ‘tera scale’ source of intentionally added airborne microplastics and fallout. The research identifies that rainfall already contains microplastics with wear and tear from car tires and synthetic textiles and clothing contributing to atmospheric pollution. In hospitals\, plastic particles may be introduced into the body via devices and treatments\, with microplastic fallout in operating rooms recorded at up to 9\,258 particles per square meter during a single shift. Cardiac catheters\, silicone breast implants\, orthopedic implants or intravenous fluid all cited as sources with the potential of inadvertently dosing patients with microplastics. Startlingly\, premature babies fed intravenously in neonatal units are estimated to receive up to 115 microplastic particles over a 72-hour feeding period from the infusion circuits alone. Baby formula intake exposes babies to microplastics at levels from <1 to 17 microplastics per gram formula with packaging types playing a role in releasing the observed microplastics. Children’s products are also of significant concern – building bricks\, baby play mats and other products for children releasing PET\, polypropylene\, polyethylene and PVC into a child’s living environment. As children naturally ingest more settled dust during play and breathe in more air per kilogram bodyweight\, their exposure is proportionally higher than adults. Another unexpected indoor exposure is via paint. Plastic is the main component of many paint products and such paint emit microplastics when it wears down or when old layers are scraped off. A single coat applied across 100 square meters is estimated to contain between 17 and 68 quadrillion polymeric particles. \nLinks:\nShocking report about our hidden microplastic exposure

SUMMARY:#10April #InternationalDayOfVolcanoes #JournéeInternationaleDesVolcans #GiornataInternazionaleDeiVulcani #DiaInternacionalDeLosVolcanes – petition 2026
DESCRIPTION:Petition proposing an ‘International Day of Volcanoes’ to be observed officially by the United Nations and we are asking that the U.N. General Assembly please consider a resolution for establishing an ‘International Day of Volcanoes’ on 10th April every year. \nTanguy De Saint-Cyr\, owner of French volcano tour company\, that came up with the concept for an ‘International Day of Volcanoes’ and Jeannie Curtis\, a New Zealand technical writer and educator are proposing an ‘International Day of Volcanoes’ to be officially recognised and observed by the United Nations and ask that the General Assembly please consider a resolution for establishing an ‘International Day of Volcanoes’ on 10th April. The date of 10th April has no recognised international day and we propose this date for the following reason: On 10 April 1815 Gunung (Mount) Tambora in Indonesia erupted and generated massive pyroclastic flows and tsunami that instantly killed 10\,000 locals\, who were unaware of the danger. The massive eruption injected huge amounts of aerosols into the Earth’s stratosphere\, causing a global haze which reflected back the incoming sunlight and cooled our planet by half a degree (celsius). This affected the planet’s climate for three years\, causing crop failure and famine\, resulting in up to 60\,000 more human deaths globally – as well as affecting animals\, fauna and agriculture. Tambora is still the deadliest eruption in recorded history\, and 10th April is a date in which the people of the World can reflect upon an “International Day of Volcanoes’ \nLinks:\nSUPPORT a proposal to United Nations for an ‘International day of Volcanoes’ to be recognised on 10th April \nInternational Day of Volcanoes

SUMMARY:J.C. Kapteyn Lezing : Traces of Ancient Genes in Modern Life
DESCRIPTION:The Neanderthals are alive – in us! \nEvolutionary geneticist and Nobel Laureate Svante Pääbo led the team that successfully sequenced the Neanderthal genome and this breakthrough revealed modern humans still carry DNA from Neanderthals. The team also discovered a previously unknown extinct Asian hominin group related to Neandertals\, which they named “Denisovans”. They found that about 2.0% of the genomes of people living outside Africa come from Neandertals while about 5.0% of the genomes of people living in Oceania come from Denisovans. In this J.C. Kapteyn Lecture\, Pääbo explains that these genetic contributions have numerous physiological and medical consequences today\, for example in growth patterns and sensitivity to pain. \nLinks:\nJ.C.

SUMMARY:Bijentelling 2026
DESCRIPTION:De Nationale Bijentelling wordt georganiseerd door Naturalis Biodiversity Center\, LandschappenNL\, en IVN Natuureducatie\, in samenwerking met EIS Kenniscentrum Insecten en Waarneming.nl en mede-initiatiefnemer Natuur & Milieu. \nHet doel is om zoveel mogelijk over bijen te weten komen\, zodat we de bij beter kunnen helpen. Daarom wordt iedereen gevraagd om mee te doen aan dit landelijk bijenonderzoek. In Nederland komen bijna 360 bijensoorten voor. Ruim de helft daarvan is bedreigd. Bijen zijn belangrijk voor bestuiving: 80% van onze eetbare gewassen en bijna 90% van onze wilde planten worden bestoven door bijen en andere insecten. Meedoen is eenvoudig\, ook voor wie weinig of geen kennis van bijen heeft. Er is een telformulier en bijengidsje waarmee iedereen de zestien verschillende soorten wilde bijen\, hommels en zweefvliegen kan herkennen. \nLinks:\nBijentelling \nHommels in het voorjaar: zo houd je ze uit elkaar + filmpje \nBijentelling Resultaten 2026 \nOpnieuw weinig hommels geteld tijdens Nationale Bijentelling

SUMMARY:#WorldAmateurRadioDay Wereld Amateur Radio Dag 2026
DESCRIPTION:Jaarlijks op 18 april vieren radioamateurs wereldwijd World Amateur Radio Day\, het was namelijk op deze dag in 1925 dat de International Amateur Radio Union (IARU) werd opgericht in Parijs. \nDe IARU behartigt wereldwijd de belangen van radioamateurs en de VERON doet dat voor alle Nederlandse amateurs via de IARU. Radioamateurs toonden als eersten aan dat het korte golfspectrum bepaald geen waardeloos stuk radiospectrum is. Integendeel\, zo bleek\, op de korte golf is wereldwijde propagatie van radiosignalen mogelijk. In alle haast om de korte golf commercieel te gaan gebruiken\, dreigden radioamateurs volledig buitengesloten te worden. Mede daarom richtten enkele radiopioniers in 1925 de IARU op. Twee jaar later\, op de International Radiotelegrapgh Conference\, kregen radioamateurs toegang tot de 10m-\, 20m-\, 40m-\, 80m- en 160m-band. Tot de dag van vandaag mogen de inmiddels 3.000.000 gelicentieerde radioamateurs deze frequentiebanden gebruiken. En behartigt de IARU wereldwijd nog steeds de belangen van radioamateurs.\n\nLinks:\nWorld Amateur Radio Day is April 18

SUMMARY:18 april\, Hoorn: tweede van tien demonstraties “Verplaats het standbeeld van J.P. Coen naar het Westfries Museum”
DESCRIPTION:Maar liefst tien demonstraties gaan We Promise en de Werkgroep Slavernijverleden Hoorn in 2026 organiseren om ervoor te zorgen dat het standbeeld van de genocidepleger Jan Pieterszoon Coen wordt verwijderd uit de openbare ruimte en verplaatst naar het Westfries Museum. \nDe demonstraties maken deel uit van een bredere verplaatsingscampagne rond het standbeeld. De eerste demonstratie van de reeks vindt plaats op 14 maart\, de laatste op 19 december. Andere onderdelen van die campagne zijn: een petitie die op 12 februari is gelanceerd\, een oproep aan organisaties om die petitie te ondersteunen\, en een officiële verplaatsingsprocedure die nog in gang moet worden gezet. Uit de oproeptekst: “Jan Pieterszoon Coen was verantwoordelijk voor extreem koloniaal geweld\, waaronder de genocide op de Banda-eilanden in 1621. Een metershoog standbeeld van genocidepleger op een centraal plein in Hoorn is geen neutrale herinnering\, maar een eerbetoon. \nLinks:\nVerplaats het standbeeld van J.P.

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
