World Metrology Day / Wereld Metrologie Dag 2026
World Metrology Day is an annual celebration of the signature of the Metre Convention on 20 May 1875 by representatives of seventeen nations, setting the framework for global collaboration in the science of measurement and in its industrial, commercial and societal applications.
The original aim of the Metre Convention – the world-wide uniformity of measurement – remains as important today as it was in 1875. The SI is now based on a set of definitions each linked to the laws of physics and have the advantage of being able to embrace further improvements in measurement science and technology to meet the needs of future users for many years to come. Indeed more widely metrology, the science of measurement, plays a central role in scientific discovery and innovation, industrial manufacturing and international trade, in improving the quality of life and in protecting the global environment. The recognition of World Metrology Day as a UNESCO International Day represents an extraordinary opportunity to promote the pivotal role of metrology in building a sustainable future

World AUTOimmune & AUTOinflammatory Arthritis Day 2026
World AUTOimmune & AUTOinflammator
Lack of awareness leads to relationship conflicts, delayed diagnosis, compromised quality of life, and elevated healthcare costs. Education about these diseases, including the fact they are full body diseases affecting many parts (joints, tissues, organs) is necessary to improve the lives of the 450 million worldwide affected.

#SavetheBees #WorldBeeDay / Wereld Bijendag 2026
World Bee Day is celebrated on 20 May, on this day Anton Janša, the pioneer of beekeeping, was baptized in 1734.
The purpose of the international day is to acknowledge the role of bees and other pollinators for the ecosystem. The UN Member States approved Slovenia’s proposal to proclaim 20 May as World Bee Day in December 2017. Bees are winged insects that form a monophyletic clade Anthophila within the superfamily Apoidea of the order Hymenoptera, with over 20,000 known species in seven recognized families. Some species – including honey bees, bumblebees, and stingless bees – are social insects living in highly hierarchical colonies, while over 90% of bee species – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary. Members of the most well-known bee genus, Apis (i.e. honey bees), are known to construct hexagonally celled waxy nests called hives. Unlike the closely related wasps and ants, who are carnivorous/omnivorous, bees are herbivores that specifically feed on nectar (nectarivory) and pollen (palynivory), the former primarily as a carbohydrate source for metabolic energy, and the latter primarily for protein and other nutrients for their larvae. They are found on every continent except Antarctica, and in every habitat on the planet that contains insect-pollinated flowering plants. The most common bees in the Northern Hemisphere are the Halictidae, or sweat bees, but they are small and often mistaken for wasps or flies.
Bees range in size from tiny stingless bee species, whose workers are less than 2 millimeters long, to the leafcutter bee Megachile pluto, the largest species of bee, whose females can attain a length of 39 millimeters. Vertebrate predators of bees include primates and birds such as bee-eaters; insect predators include beewolves and dragonflies. Bees are best known for their ecological roles as pollinators and, in the case of the best-known species, the western honey bee, for producing honey, a regurgitated and dehydrated viscous mixture of partially digested monosaccharides kept as food storage of the bee colony. Pollination management via bees is important both ecologically and agriculturally, and the decline in wild bee populations has increased the demand and value of domesticated pollination by commercially managed hives of honey bees. Human beekeeping or apiculture (meliponiculture for stingless bees) has been practiced as a discipline of animal husbandry for millennia, since at least the times of Ancient Egypt and Ancient Greece. Bees have appeared in mythology and folklore, through all phases of art and literature from ancient times to the present day, although primarily focused in the Northern Hemisphere where beekeeping is far more common. In Mesoamerica, the Maya have practiced large-scale intensive meliponiculture since pre-Columbian times.

Nieuw evenwicht in het energiesysteem : Kritieke materiaalvraag voor een klimaatneutraal Nederland in 2040 – publicatie
Schoner en onafhankelijker energiesysteem binnen planetaire grenzen is haalbaar met strategisch beleid.
Met strategische beleidskeuzes kan Nederland haar energie-onafhankelijkheid vergroten en tegelijkertijd het klimaat en cruciale ecosystemen beschermen. Dat blijkt uit het onderzoek ‘Nieuw evenwicht in het energiesysteem‘ van Copper8, Quintel en Polaris Sustainability in opdracht van Greenpeace Nederland. Het onderzoek laat zien dat een explosieve groei van transitiemetalen, voor onder andere zonnepanelen, windturbines en batterijen, geen gegeven is, maar een keuze. Ten opzichte van de huidige projecties kan de vraag naar transitiemetalen in de periode tot en met 2050 met 42 – 49% worden verlaagd door energiebesparing en innovatie. Mijnbouw in kwetsbare ecosystemen, waaronder de diepzee, is dan niet nodig.

De Straat Op : Vluchtelingen welkom
Na het geweld de afgelopen weken is het tijd voor een ander geluid: de straat op vóór solidariteit, WEES WELKOM zeggen tegen mensen op de vlucht.
Want waar je ook vandaan komt, wat voor huidskleur of religie je ook hebt, uiteindelijk willen en verdienen we allemaal hetzelfde. Een veilig huis, een veilige toekomst voor onze kinderen, betaalbare boodschappen. Daarom gaan 99 organisaties naast onze buren staan, of ze nou gevlucht zijn of altijd in een veilig land hebben gewoond, of ze een migratieachtergrond hebben of nooit uit hun geboorteland zijn verhuisd. Een samenleving maak je samen.

Wereld IBD dag / World IBD Day 2026
IBD staat voor Inflammatory Bowel Disease en is de verzamelnaam voor de chronische darmziekten colitis ulcerosa en de ziekte van Crohn.
Voor patiënten met colitis ulcerosa en de ziekte van Crohn is dat geen symbolische dag, maar een herkenning van hun dagelijkse werkelijkheid. Klachten die komen en gaan, energie die beperkt is en een ziekte die vaak onzichtbaar blijft. Chronische ontsteking van het spijsverteringskanaal of darm, IBD, raakt niet alleen de patiënt zelf. Ook partners, ouders en kinderen bewegen mee met de ziekte. Dat maakt het thema van Wereld IBD Dag in 2026, ‘Met elkaar sterker’, concreet en dichtbij. Want omgaan met IBD doe je niet alleen.

#WorldFamilyDoctorDay Wereldhuisartsendag 2026
World Family Doctor Day (FDD) – 19th May – was first declared by WONCA in 2010 and it has become a day to highlight the role and contribution of family doctors and primary care teams in healthcare systems around the world.
This celebration is the perfect opportunity to acknowledge the central role of Family Doctors in the delivery of personal, comprehensive and continuing health care for all patients. It’s also a chance to celebrate the progress being made in family medicine and the special contributions of primary care teams globally. In 2026, FFD celebrates family doctors navigating a world reshaped by digital technology, bringing their values of compassion, continuity and person-centred care into the digital age. Artificial intelligence can detect patterns, generate documentation and optimise workflows. But it cannot recognise hesitation. It cannot interpret silence. It cannot perceive fear behind polite reassurance. In many of our cultures, meaning is conveyed indirectly, through tone, through pauses, and through relationship built over years. No algorithm captures that.
