BASE experiment at CERN succeeds in transporting antimatter - publication
2026-03-24
The experiment successfully transported a trap filled with antiprotons across CERN’s main site, a remarkable first step towards delivering antimatter to other European laboratories.
a team of scientists from the BASE experiment at CERN successfully transported a trap filled with antiprotons in a truck across the Laboratory’s main site. The team managed to accumulate a cloud of 92 antiprotons in an innovative portable cryogenic Penning trap, then disconnect it from the experimental facility, load it onto a truck and continue experiment operation after transport. This is a remarkable achievement, given that antimatter is very difficult to preserve, as it annihilates upon contact with matter. This world premiere is a test, the ultimate aim being to transport antiprotons to other European laboratories, such as Heinrich Heine University Düsseldorf (HHU), where very-high-precision measurements of the antiproton properties could be performed. Antimatter is a naturally occurring class of particles that is almost identical to ordinary matter except that the electric charge and magnetic moment are reversed. According to the laws of physics, the Big Bang should have produced equal amounts of matter and antimatter. These equal-but-opposite particles would have quickly annihilated each other, leaving an empty Universe. However, our Universe contains predominantly matter, and this imbalance has baffled scientists for decades. Physicists suspect that there are hidden differences that may explain why matter survived and antimatter all but disappeared.

The scientific study ‘Mapping pesticide mixtures to cancer risk at the country scale with spatial exposomics‘ reveals a strong link between exposure to agricultural pesticides in the environment and the risk of developing cancer.
By combining environmental data, a nationwide cancer registry, and biological analyses, researchers from the IRD, the Institut Pasteur, the University of Toulouse, and the National Institute of Neoplastic Diseases (INEN) in Peru have shed new light on the role of pesticide exposure in the development of certain cancers. Pesticides are widely present in food, water, and the environment, often in the form of complex mixtures. Until now, it has been difficult to accurately assess their effects on human health, as most studies focus on isolated substances and experimental models that are far removed from real-world exposure conditions. This new study adopts an innovative, integrative approach that accounts for the complexity of real-world exposures experienced by populations.

#CitizenScience Month 2026
2026-04-01 - 2026-04-30
SciStarter established an annual Citizen Science Month in April to celebrate and bring greater awareness to the valuable contributions of the public to scientific research and data collection endeavors.
Citizen science (similar to community science, crowd science, crowd-sourced science, civic science, participatory monitoring, or volunteer monitoring) is research conducted with participation from the general public, or amateur/nonprofessional researchers or participants for science, social science and many other disciplines. There are variations in the exact definition of citizen science, with different individuals and organizations having their own specific interpretations of what citizen science encompasses. Citizen science is used in a wide range of areas of study including ecology, biology and conservation, health and medical research, astronomy, media and communications and information science. There are different applications and functions of citizen science in research projects. Citizen science can be used as a methodology where public volunteers help in collecting and classifying data, improving the scientific community’s capacity. Citizen science can also involve more direct involvement from the public, with communities initiating projects researching environment and health hazards in their own communities. Participation in citizen science projects also educates the public about the scientific process and increases awareness about different topics. Some schools have students participate in citizen science projects for this purpose as a part of the teaching curriculums.

Maand van de Filosofie 2026
2026-04-01 - 2026-04-30
April is in 2026 al 25 jaar de Maand van de Filosofie!
Jaarlijks worden in april door heel Nederland en Vlaanderen filosofische nachten, programma’s, lezingen, debatten en festivals georganiseerd rondom het thema van de Maand van de Filosofie. Het thema van 2026 is ‘Ken onszelve’. Elk jaar verschijnt er een nieuw filosofisch essay, wordt de Socratesbeker uitgereikt aan het beste filosofieboek van het jaar en eens in de twee jaar wordt een nieuwe Denker des Vaderlands uitgeroepen. De filosofie of wijsbegeerte is de oudste theoretische discipline die het verlangen en het streven uitdrukt naar kennis en wijsheid. Zij kwam voor het eerst echt op in de 6e eeuw voor de Gregoriaanse jaartelling. Een beoefenaar van de filosofie wordt een filosoof of wijsgeer genoemd. In het dagelijks spraakgebruik wordt de term filosofie gebruikt om elke vorm van wijsheid of levensbeschouwing aan te duiden (zoals in “iemands filosofie”) of iemands uitgangspunten (zoals in “het sluit niet aan op de filosofie achter dit plan”). Dit verschilt van het begrip filosofie in een academische context.

Inzicht in openbare kwaliteitsinformatie in de medischspecialistische zorg : Nulmeting van de huidige staat van transparantie - publicatie
2026-04-02 | Nederland, Nederland
In het rapport ‘Inzicht in openbare kwaliteitsinformatie in de medischspecialistische zorg : Nulmeting van de huidige staat van transparantie‘ staat een nulmeting Zorginstituut Nederland en Patiëntenfederatie Nederland over de transparantie van kwaliteitsinformatie in de medisch-specialistische zorg.
Uit dit onderzoek blijkt dat er weinig informatie over de kwaliteit van zorg openbaar is voor patiënten. En dat de hoeveelheid openbare kwaliteitsinformatie de afgelopen jaren nauwelijks toeneemt. In het rapport staan de resultaten. Deze meting is uitgevoerd om een stand van zaken te krijgen over de huidige mate van transparantie van kwaliteitsinformatie in de medisch-specialistische zorg in Nederland. Deze meting volgt uit de afspraken van het Aanvullend Zorg- en Welzijnsakkoord (AZWA). Hierin staan afspraken die partijen maken om meer informatie over kwaliteit van zorg transparant te maken. Door de jaren heen zijn meerdere afspraken gemaakt om kwaliteitsinformatie voor patiënten transparant te maken, maar deze afspraken werden ook uitgesteld. Dat roept vragen op: wat is nu eigenlijk de stand van zaken? Zijn de afspraken tussen partijen in het veld en de overheid nagekomen? En zijn hiermee de beloftes aan de patiënt waargemaakt?

Exploring Everyday Microplastic Exposures - publication
2026-04-08
The report ‘Exploring Everyday Microplastic Exposures‘ reveals shocking scale of hidden global microplastic exposure.
The 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.

#10April #InternationalDayOfVolcanoes #JournéeInternationaleDesVolcans #GiornataInternazionaleDeiVulcani #DiaInternacionalDeLosVolcanes – petition 2026
2026-04-10
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.
Tanguy 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’
