SUMMARY:IceCube Neutrino Observatory
DESCRIPTION:The IceCube Neutrino Observatory (or simply IceCube) is a neutrino observatory constructed at the Amundsen–Scott South Pole Station in Antarctica\, the project is a recognized CERN experiment (RE10). \nIts thousands of sensors are located under the Antarctic ice\, distributed over a cubic kilometre. Similar to its predecessor\, the Antarctic Muon And Neutrino Detector Array (AMANDA)\, IceCube consists of spherical optical sensors called Digital Optical Modules (DOMs)\, each with a photomultiplier tube (PMT) and a single-board data acquisition computer which sends digital data to the counting house on the surface above the array. IceCube was completed on 18 December 2010. DOMs are deployed on strings of 60 modules each at depths between 1\,450 and 2\,450 meters into holes melted in the ice using a hot water drill. IceCube is designed to look for point sources of neutrinos in the teraelectronvolt (TeV) range to explore the highest-energy astrophysical processes. In November 2013 it was announced that IceCube had detected 28 neutrinos that likely originated outside the Solar System. \nLinks:\nIceCube Neutrino Observatory \nIceCube: the coolest way to detect neutrinos (TV The Royal Institution) \nIceCube: the coolest way to detect neutrinos \nANITA experiment \nOur galaxy seen through a new lens: neutrinos detected by IceCube \n[LIVE] Observation of high-energy neutrinos from the Galactic plane

SUMMARY:Manifest tegen de uitverkoop van wetenschap
DESCRIPTION:Foodwatch roept op het manifest ‘Stop de uitverkoop van wetenschap!’ massaal te ondertekenen. \nVia het manifest wordt bijgedragen aan het debat over de uitverkoop van wetenschap\, maar Foodwatch hoopt dat het niet alleen bij woorden blijft. Het manifest stelt daarom acties voor om de uitverkoop van voedingswetenschap tegen te gaan. Dit zijn natuurlijk niet de enige mogelijke acties om onafhankelijke voedingswetenschap te waarborgen. Door concrete maatregelen voor te stellen\, hopen we dat de verschillende spelers zich geroepen voelen om actie te ondernemen. \nLinks:\nManifest ‘Stop de uitverkoop van wetenschap!\n\nWageningse voedingswetenschappers overschrijden gedragscode : Transparantie over nevenfuncties – publicatie \nVerkenning Wetenschappelijke Integriteit \nVertrouwen in wetenschap licht gestegen

SUMMARY:Surface Water and Ocean Topography (SWOT) mission
DESCRIPTION:The Surface Water and Ocean Topography (SWOT) mission is a satellite altimeter jointly developed and operated by NASA and CNES\, the French space agency\, in partnership with the Canadian Space Agency (CSA) and UK Space Agency (UKSA). \nThe objectives of the mission are to make the first global survey of the Earth’s surface water\, to observe the fine details of the ocean surface topography\, and to measure how terrestrial surface water bodies change over time. While past satellite missions like the Jason series altimeters (TOPEX/Poseidon\, Jason-1\, Jason-2\, Jason-3) have provided variation in river and lake water surface elevations at select locations\, SWOT will provide the first truly global observations of changing water levels\, stream slopes\, and inundation extents in rivers\, lakes\, and floodplains. In the world’s oceans\, SWOT will observe ocean circulation at unprecedented scales of 15–25 km (9.3–15.5 mi)\, approximately an order of magnitude finer than current satellites. Because it uses wide-swath altimetry technology\, SWOT will almost completely observe the world’s oceans and freshwater bodies with repeated high-resolution elevation measurements\, allowing observations of variations. \nLinks:\nSurface Water and Ocean Topography at NASA.gov \nOcean Surface Topography from Space at NASA.gov \nCnes project Library at CNES.fr \nAVISO+ portal for SWOT

SUMMARY:Water op de Kaart
DESCRIPTION:De campagne ‘Water op de kaart’ van het Nederlands Instituut voor Ecologie (NIOO-KNAW) en de stichting Natuur & Milieu moet een beeld gaan geven van de kwaliteit van water rond een riooloverstort. \nZo’n 40 burgerwetenschappers verspreid over Nederland gaan in hun eigen buurt monsters nemen van de zogenaamde kleine oppervlaktewateren: de sloten of vijvers om de hoek. Dat water blijkt namelijk van niet zo’n goeie kwaliteit. Bij hevige plensbuien\, die in toenemende mate voorkomen\, komt het riool vol met water te zitten en stroomt het over naar omliggende sloten en plassen. Daar zit het probleem. Door die overstort komen stoffen uit het riool als medicijnresten en poep en plas in het oppervlaktewater terecht. Het project ‘Water op de kaart’ is een vervolg op het onderzoek Vang de Watermonsters\, waarbij burgerwetenschappers vijf jaar achter elkaar de waterkwaliteit onderzochten. \nLinks:\nWater op de Kaart \nBurgerwetenschappers gaan jaar lang waterkwaliteit meten

SUMMARY:Waterdier van het jaar 2025 : eendagsvlieg
DESCRIPTION:2025 staat bij Waterdiertjes.nl in het teken van de eendagsvlieg. \nOndanks hun naam leven eendagsvliegen langer dan één dag – hun larven brengen vaak een jaar door in het water voordat ze uitvliegen. In 2025 onderzoekt Waterdiertjes.nl de verspreiding van deze larven in Nederland om meer te leren over hun leefomgeving en de waterkwaliteit. Help jij de wetenschappers om dit waterdier in kaart te brengen? \nLinks:\n2025: jaar van de eendagsvlieg \nHet jaar van de eendagsvlieg

SUMMARY:Year of Quantum Science and Technology
DESCRIPTION:The International Year of Quantum Science and Technology (IYQ) recognizes 100 years since the initial development of quantum mechanics and is a United Nations observance that aims to highlight the contributions of quantum science and practical applications of quantum technology. \nThe mission of the IYQ is to use the occasion of 100 years of quantum mechanics in 2025 to help raise public awareness of the importance and impact of quantum science and applications on all aspects of life. Anyone\, anywhere can participate in IYQ by helping others to learn more about quantum on this centennial occasion or simply taking the time to learn more about it themselves. No One Owns Quantum Science No individual\, society\, country\, institution\, or discipline can claim ownership of the past or future of quantum science; it is knowledge that should be free to all. IYQ recognizes those who put effort into studying\, developing\, investigating\, using\, and teaching quantum science and technology\, while seeking to solicit and answer questions from anyone who wants to learn more about it. Those who have insights into the beauty\, power\, and importance of quantum science and technology should use IYQ as a moment to share these insights with people who are less familiar with quantum. IYQ asks everyone to make an effort to reach out to people with different cultural backgrounds and aesthetic sensibilities. \nIf you’re inclined to present or seek out a unified story\, make note of where others dissent. If you’re inclined to highlight disputes and controversies\, recognize where there is consensus. If you’re inclined to promote or to understand established knowledge\, make note of what is still unknown. Manythings have been and will be said about quantum science and technology that are untrue or misleading. The remedy for these statements is more quantum speech. All people proceed from learning simple\, sometimes incorrect stories to deeper\, more nuanced ones. IYQ aims to meet people where they are in their understanding and help them to construct pathways for this journey. There is often a disparity between how we hope scientific inquiry is conducted and how it is actually practiced by individuals and institutions. IYQ is an opportunity to communicate and model the ideals of how science should be practiced in the hope that future generations will take up these values. Pride in the past and optimism about the future are welcome\, and stories often have to be simplified out of necessity\, but IYQ should always aim to foreground honesty about the past and future of quantum science and technology. If quantum has brought joy to your life\, share this joy with others. \nLinks:\nYear of Quantum Science and Technology \nKwantummechanica \nOpening Ceremony of the International Year of Quantum Science and Technology

SUMMARY:Mount Lewotobi Laki-laki - eruptions June / July 2025
DESCRIPTION:Lewotobi is a twin volcano located in the southeastern part of the island of Flores\, Indonesia\, it has two peaks; the Lewotobi Laki-laki (Male Lewotobi) and Lewotobi Perempuan (Female Lewotobi) stratovolcanoes\, the more active Lewotobi Laki-laki is about 2.1 km northwest of the taller Lewotobi Perempuan. \nOn 21 March\, Lewotobi Laki-laki erupted\, sending ash clouds over 8 km high. Authorities raised the alert to the highest level\, and Jetstar canceled some flights to Bali. The eruption followed smaller ones since 13 March. One person was injured during the evacuations\, although the details reported were unclear. Bali airport remained open\, but seven international flights were canceled. The geological agency warned of lava floods and continued activity. Lewotobi Laki-laki erupted again on 18 May\, prompting authorities to raise Indonesia’s highest volcanic alert level. Lewotobi Laki-laki erupted on 17 June\, sending ash clouds 11 km high\, prompting authorities to raise Indonesia’s highest volcanic alert level again\, with a plume visible from a distance of 90 km to 150 km. Multiple flights were cancelled due to the amount volcanic ash released into the atmosphere. Two major eruptions occurred on 7 July\, ejecting debris as far as 8 km away and producing pyroclastic flows that reached 5 km from the crater and an ash cloud 13 km high. At least 24 flights were cancelled in Bali. \nLinks:\nIndonesia’s Mount Lewotobi Laki-laki spews 11 kilometre high ash cloud after eruption \nAlert raised to the highest level after Indonesia’s Mount Lewotobi Laki Laki volcano erupts \nIndonesia volcano spews ash more than 6 miles into sky\, dozens of Bali flights canceled \nLewotobi – Pusat Vulkanologi dan Mitigasi Bencana Geologi

DESCRIPTION: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. \nCitizen 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. \nLinks:\nCitizen Science Month \nCitizen Science Month – USGS \nApril is Citizen Science Month \nKennis Burgerwetenschap

SUMMARY:Maand van de Filosofie 2025
DESCRIPTION:April is de Maand van de Filosofie\, jaarlijks worden tijdens deze maand door heel België en Nederland filosofische nachten\, programma’s\, lezingen\, debatten en festivals georganiseerd. \nElk 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. \nLinks:\nMaand van de Filosofie

SUMMARY:Onderzoek naar het voedingsgedrag van wolven (Canis lupus) in Nederland in 2023 - publicatie
DESCRIPTION:Wolven in Nederland eten vooral wilde hoefdieren zoals reeën\, wilde zwijnen en edelherten maar ook natuurgrazers in wildarme gebieden. \nOnder meer in Drenthe\, voeden wolven zich ook met in het wild levende runderen die worden ingezet voor natuurbeheer. Dat blijkt uit een onderzoek naar de ontlasting van de wolven in ons land. Het onderzoek naar het voedingspatroon van de wolven in Nederland\, uitgevoerd door het Centrum voor Milieuwetenschappen van de Universiteit Leiden\, Stichting Leo\, Universiteit Antwerpen en de Zoogdiervereniging\, bracht het voedingspatroon van wolven in 2023 gedetailleerd in kaart. Uit de resultaten blijkt dat op de Veluwe\, wilde zwijnen (aanwezig in 62% van de onderzochte uitwerpselen)\, reeën (56%) en edelherten (32%) de voornaamste prooidieren zijn. In Drenthe\, waar vrijwel alleen reeën in het wild voorkomen\, voeden wolven zich naast reeën (aangetoond in 63% van de uitwerpselen) ook met natuurrunderen (43%) die ingezet worden voor natuurbeheer\, en schapen (10%). Het onderzoek is een langdurige studie die in ieder geval loopt tot en met 2025. De wetenschappelijke bevindingen kunnen bijdragen aan het maatschappelijk debat\, maar ook aan de onderbouwing van een beter beleid voor wolven in Nederland. Er is nu voor het eerst objectieve informatie over het wolvendieet in Nederland. De onderzoekers hopen dat deze informatie bijdraagt aan de inspanningen om een vreedzaam samenleven van mens en wolf in Nederland mogelijk te maken. \nLinks:\nWolven in Nederland eten vooral wild\, maar ook natuurgrazers in wildarme gebieden \nWolven in Nederland eten relatief weinig schapen\, zeggen onderzoekers

SUMMARY:The MICrONS Project : anatomical images of individual cells in mouse visual cortex - publications
DESCRIPTION:The MICrONS Project published package of papers about an unprecedented dataset of high resolution anatomical images of individual cells in mouse visual cortex\, mapped on to their responses. \nThis integrated view of function and structure lays a foundation for discovering the computational bases of cortical circuits. A cubic millimetre might not sound like much — roughly the size of a grain of sand — but to neuroscientists\, it is enormous. One cubic millimetre of a mammalian brain contains tens of thousands of neurons with hundreds of millions of connections\, or synapses\, between them. For most of the history of neuroscience\, tracing the detailed connectivity (or connectomics) and measuring activity of neurons at such a large scale was unthinkable. Instead\, neuroscientists worked at more manageable scales — even single pairs of connected cells can provide important information\, especially when accrued over hundreds of labs doing similar experiments. Nevertheless\, the goal of studying millimetre-scale volumes of brain in such detail started to come closer after a period of intense focus on new neuroscience technologies in the 1990s and 2000s. This period led to tools to label\, trace and image the activity of neurons in increasingly large populations. However\, the fundamental problem of scale remained. A complete reconstruction of a cubic millimetre of neurons requires roughly a petabyte of data. Tracing the intricate branches of the neurons is far too time consuming to do by hand\, so improved tools for automation were needed. A parallel revolution in computing — increased computing power and advances in machine learning and artificial intelligence — suddenly made those challenges tractable. This brings us to today’s announcement of the MICrONS project. The team made and designed tools to allow dense neural reconstruction at scale. The resulting data set includes 200\,000 cells and 523 million connections in the primary visual cortex and surrounding areas of a mouse. A unique contribution of the MICrONS project is that it also includes in vivo functional data from around 75\,000 of the neurons. Even landmark connectomics studies\, such as FlyWire\, include only the anatomical data. The inclusion of functional data means that we can directly relate connectivity to function and decipher the elusive algorithms of the cortex. \nLinks:\nThe MICrONS Project – Nature

SUMMARY:#10April #InternationalDayOfVolcanoes #JournéeInternationaleDesVolcans #GiornataInternazionaleDeiVulcani #DiaInternacionalDeLosVolcanes – petition 2025
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:Kenniscafé Groningen : Een streep door de Wadden
DESCRIPTION:De Wadden\, sinds 2009 UNESCO Werelderfgoed\, is een beschermd natuurgebied; onvervangbaar\, uniek en ‘eigendom van de hele wereld’ – net als het Great Barrier Reef en de Grand Canyon. \nHet Waddengebied spreekt tot de verbeelding: het landschap is continu in verandering en het is rijk aan biodiversiteit. De Wadden zijn echter meer dan de idylle van de rosse grutto’s\, zeehonden en wadlopen. Toerisme\, visserij en industrie verstoren het ecologische systeem\, wat leidt tot verlies van biodiversiteit\, maar ook tot het verdwijnen van de culturele diversiteit van de Waddeneilanden. Menselijke ingrepen in het verleden\, zoals de aanleg van de Afsluitdijk\, hebben grote ecologische schade aangericht. De gaswinning heeft geleid tot verslibbing en verarming van het bodemleven. Tegenwoordig vormen windmolens en stroomkabels een grote bedreiging voor de Wadden. Hoe beschermen we de Wadden? Kunnen we de ecologie van de Wadden herstellen? En bestaan de Wadden over honderd jaar nog wel? \nLinks:\nEen streep door de Wadden
