#WorldIPDay World Intellectual Property Day / Werelddag voor Intellectueel Eigendom 2026

World Intellectual Property Day is observed annually on 26 April.

The event was established by the World Intellectual Property Organization (WIPO) in 2000 to “raise awareness of how patentscopyrighttrademarks and designs impact on daily life” and “to celebrate creativity, and the contribution made by creators and innovators to the development of societies across the globe”. 26 April was chosen as the date for World Intellectual Property Day because it coincides with the date on which the Convention Establishing the World Intellectual Property Organization entered into force in 1970. This event has been criticized by a number of activists and scholars as one-sided propaganda in favor of traditional copyright, ignoring alternatives related to copyleft and the free culture movement.

In het radioprogramma wordt het gesproken woord omlijst door licht klassieke muziek en salonmuziek. Het radioprogramma werd in 1978 voor het eerst uitgezonden door de VARA en is een van de langst lopende en best beluisterde radioprogramma’s van de publieke omroep. Het wordt elke zondagmorgen uitgezonden tussen 07:00 en 10:00 op NPO Radio 1. De beginmuziek is een bewerking van Vivaldi’s “Piccolo Concerto in C major” (RV 443).

Op twee locaties zagen vogelringers rare sterfgevallen en neurologische verschijnselen bij zwaluwen. De vogels bleken veel insecticiden op hun veren te hebben. Wie aan mummies denkt, dwaalt af naar het oude Egypte. Maar voor mummiekatten, -otters en zelfs mensen kan je ook gewoon in Nederland blijven. Deel twee van het Nationaal Vogelconcert met een hoofdrol voor het geluid van de eider. En verder: biodiversiteit op het erf, het lied van Agilouz, trek van de winde en De column is van Bibi Dumon Tak. Vroege Vogels Radio wordt gepresenteerd door Jan van Poppel vanuit het Groene Huis in Amersfoort.

De tv editie wordt uitgezonden via NPO 2 op zondag, vaak rond een thema.

Honderden grote zilverreigers strijken neer in de Lettelberterpetten om te slapen, terwijl aan de overkant van het Leekstermeer blauwe kiekendieven de nacht ingaan. In dit natte grensgebied tussen Drenthe en Groningen wemelt het van soorten die afhankelijk zijn van water. We zien rietgorzen op zoek naar eten en waterroofkevers tussen de krabbenscheer. De filmploeg loopt mee met jonge natuurliefhebbers die de muizenpopulatie in de gaten houdt. Ze ontdekken niet alleen de kritische waterspitsmuis, die hier juist talrijk is. Ze worden ook nog verrast door de nog veel zeldzamere bosspitsmuis.

DNA Day 2026

DNA

DNA Day is a United States holiday celebrated on April 25, it commemorates the day in 1953 when James WatsonFrancis CrickMaurice WilkinsRosalind Franklin and colleagues published papers in the journal Nature on the structure of DNA.

Furthermore, 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.

White House Correspondents’ Association Annual Dinner / Correspondents’ Dinner 2026

WHCA

The White House Correspondents’ Association (WHCA) annual dinner, begun in 1921, traditionally held on the evening of the last Saturday in April at the Washington Hilton, has become a Washington, D.C. tradition, and is attended by the president and vice president.

Until 1962, the dinner was open only to men, even though WHCA’s membership included women. At the urging of Helen Thomas, President John F. Kennedy refused to attend the dinner unless the ban on women was dropped. Prior to World War II, the annual dinner featured singing between courses, a homemade movie, and an hour-long, post-dinner show with big-name performers. Since 1983, the featured speaker has usually been a comedian, with the dinner taking on the form of a comedy roast of the president and his administration. The dinner also funds scholarships for gifted students in college journalism programs. Many annual dinners have been cancelled or downsized due to deaths or political crises. The dinner was cancelled in 1930 due to the death of former president William Howard Taft; in 1942, following the United States’ entry into World War II; and in 1951, over what President Harry S. Truman called the “uncertainty of the world situation.” In 1981, Ronald Reagan did not attend because he was recuperating after the attempted assassination the previous month, but he did phone in and told a joke about the shooting. During his first presidencyDonald Trump did not attend the dinners in 2017, 2018, and 2019. Trump indicated that he might attend in 2019 since this dinner did not feature a comedian as the featured speaker. However, on April 5, 2019, he announced that he again would not attend, calling the dinner “so boring, and so negative,” instead hosting a political rally that evening in Wisconsin.

On April 22, Trump ordered a boycott of the dinner, with White House Cabinet Secretary Bill McGinley assembling the agencies’ chiefs of staff to issue a directive that members of the administration not attend. However, some members of the administration attended pre- and post-dinner parties. After the April 30, 2022 dinner, several attendees, including Secretary of State Antony Blinken, tested positive for COVID-19. However, no cases of serious illness were reported as a result of the dinner. At the 2024 White House Correspondents’ Dinner, pro-Palestinian protesters shouted “Shame on you!” at arriving attendees. Trump also declined to attend the dinner in 2025, the first year of his second presidency. Some members of his administration were also absent from the dinner and instead attended the launch party for Executive Branch, a new private club in Georgetown that is owned by Donald Trump Jr. and others with ties to the administration. He attended the dinner in 2026 before evacuating after gunshots were heard. After officers secured the Washington Hilton hotel building, the guests at the dinner departed the hotel. The first lady, Melania Trump, was also in attendance and evacuated promptly alongside her husband. An alleged shooter was arrested.

World Malaria Day / Wereld Malaria Dag

WHO and partners will mark World Malaria Day by celebrating the achievements of countries that are approaching – and achieving – malaria elimination.

They provide inspiration for all nations that are working to stamp out this deadly disease and improve the health and livelihoods of their populations. On World Malaria Day 2026, the World Health Organization joins partners to launch the campaign: “Driven to End Malaria: Now We Can. Now We Must“. This is a rallying cry to grasp the moment—to protect lives now and fund a malaria-free future.

World Penguin Day / Wereld Pinguïn Dag 2026

April 25th is World Penguin Day. This celebratory day coincides with the annual northern migration of Adelie penguins.

This intrinsic migration pattern is conserved across generations. Native to Antarctica are six breeding species, Emperor, King, Chinstrap, Adelie, Gentoo and Macaroni penguins. Most penguins are monogamous and have distinct calls, enabling them to locate their mates in large groups. Penguin species lay up to two eggs per mating season with the Emperor and King penguins laying only one egg. Alarmingly, of the 17 recognized living species, 11 have been listed as Vulnerable or Endangered.
