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

SUMMARY:Stop de sloop van het hoger onderwijs - stakingsdag
DESCRIPTION:Het (voormalig) kabinet geeft geen ene moer om onderwijs en wetenschap\, in de voorjaarsnota zijn zelfs extra bezuinigingen aangekondigd: Dit is geen bezuiniging meer\, dit is een regelrechte sloopoperatie. \n25.000 mensen stonden er op het Malieveld\, en tijdens de estafettestakingen kwamen nog eens 32.500 mensen in actie. Toch gaat het kabinet door met de sloop van ons onderwijs: in de voorjaarsnota zijn zelfs extra bezuinigingen van 400 miljoen aangekondigd. Daarom wordt op 10 juni 2025 opnieuw door medewerkers en studenten in het hoger onderwijs het werk neergelegd\, de locatie van de stakingsmanifestatie is (verplaatst naar) De Dam in Amsterdam. De eis blijft staan: alle bezuinigingen moeten van tafel. De staking is een initiatief van onder andere WO in Actie\, de AOb en FNV\, de studentenvakbonden en diverse actiegroepen. \nLinks:\nKabinet sloopt hoger onderwijs \n10 juni nieuwe landelijke stakingsdag hoger onderwijs!

SUMMARY:TED Countdown Summit 2025
DESCRIPTION:The TED Countdown Summit will bring together a visionary group of global innovators\, business executives\, scientists\, policymakers\, next-generation leaders\, artists\, activists — all united in their commitment to building a brighter future. \nOur world is in the midst of a hard reset. Institutions are faltering\, and achievements\, like the Paris Agreement\, appear increasingly precarious. Critical challenges that mark everyday life remain unresolved\, deepening fears about our shared future. Yet amid these headwinds\, there are clear signs of progress toward a better world. Booming clean energy industries in China\, the end of coal in the U.K.\, and a new generation of leaders in Kenya committed to leapfrogging old patterns of development\, all point the way forward. Positive tipping points – many already in motion – can take us further\, faster. There is no path to achieving the Paris goals that does not run through Africa. That’s why we’ve chosen to host the 2025 Summit in Nairobi\, a city on the vanguard of the continent’s energy transition. Kenya boasts one of the greenest grids in the world\, with 90% of its electricity from renewables and 50% of this from geothermal. With 70% of its population under 30\, Kenya is also home to a new generation of leaders committed to leapfrogging old patterns and pioneering a resilient path to economic development. In Nairobi\, we will gather to learn from one another\, bridge divides\, and harness the wisdom and creativity of a remarkable network of leaders spanning sectors and geographies. The TED Countdown Summit will gather innovative thinkers and radical changemakers to inspire commitment and collaboration\, fast-track solutions\, and create a world that proves better than we think. \nLinks:\nTED Countdown Summit 2025

SUMMARY:Tübinger Mediendozentur 2025 mit Harald Lesch „Die informierte Gesellschaft und ihre Feinde“ (TV webcast)
DESCRIPTION:Im Rahmen der 20. Tübinger Mediendozentur hält Astrophysiker und Bestsellerautor Prof. Dr. Harald Lesch\, einer der bekanntesten Wissenschaftler des Landes\, am Mittwoch\, den 25. Juni 2025\, einen Vortrag im Festsaal der Universität (Neue Aula\, Geschwister-Scholl-Platz). \nIn seinem Vortrag mit dem Titel „Die informierte Gesellschaft und ihre Feinde“ geht es um die Frage\, wie das Zusammenspiel von Populismus\, sozialen Medien und Künstlicher Intelligenz die Idee von Wahrheit\, den Charakter von Debatten und die politischen Verhältnisse verändert – auf dem Weg zu einer polarisierten\, von Hypes und Hysterien regierten Gesellschaft\, der die nötige Kompromiss- und Konsensfindung im Angesicht ineinander verschlungener Großkrisen immer schwerer fällt. \nLinks:\nMediendozentur 2025 mit Harald Lesch (mit Video) Vortrag zum Thema „Die informierte Gesellschaft und ihre Feinde“

SUMMARY:Tau-Dag / Tau Day 2025
DESCRIPTION:Tau (τ) [/tɑu/] heeft\, in navolging van pi-dag\, ook een eigen dag: tau-dag. \nTau is de 19e letter van het Griekse alfabet\, is in 2010 door fysicus-ondernemer Michael Hartl voorgestelde symbool voor de wiskundige constante tweemaal pi (2π)\, welke constante sinds 2001 wordt gepropageerd door initiatiefnemer Bob Palais (wiskundehoogleraar) en een groep medestanders als vervanging van de cirkelconstante π. Door τ te gebruiken in formules\, in plaats van 2π\, kunnen wiskundige formules worden verkort. Uit de formule voor de omtrek van een cirkel volgt dat een volledige cirkel overeenkomt met τ radialen. \nLinks:\nThe Tau Manifesto \nState of the Tau 2024
