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:Lewotobi Laki-laki - eruption 2024
DESCRIPTION:An eruption is ongoing since 23 December 2023 in Lewotobi\, twin volcano (Lewotobi Laki-laki (Male Lewotobi) and Lewotobi Perempuan (Female Lewotobi) stratovolcanoes) located in the southeastern part of the island of Flores\, Indonesia\, displacing up to 6\,500 people as of January 2024. \nOn 4 November 2024\, the volcano spewed molten debris at several villages some 4 kilometers (km) away\, destroying homes and killing at least nine. The Centre of Volcanology and Geological Hazard Mitigation recommended that a 7 km radius around the volcano be evacuated. Seven villages were affected by the eruption. A larger eruption occurred on November 7. On November 8\, the volcano erupted several times\, one bearing an ash plume with a height reaching 10 km. \nLinks:\nIndonesia’s Mount Lewotobi Laki Laki continues to unleash towering column of hot clouds \nLewotobi volcano\, Flores\, Indonesia

SUMMARY:2024: jaar van de kokerjuffer
DESCRIPTION:In 2024 kun je weer helpen met het in kaart brengen van de biodiversiteit van de Nederlandse wateren door waterdiertjes te tellen en je waarnemingen door te geven. \nIn 2024 wordt één van deze waterdieren extra in het zonnetje gezet: de kokerjuffer\, de larve van de schietmot. Deze beestjes zijn niet alleen belangrijk voor de wetenschap omdat ze ons iets vertellen over de waterkwaliteit\, maar zijn ook ontzettend leuk om te vangen omdat ze prachtige kokertjes bouwen. Kokerjuffers gebruiken verschillende materialen om hun koker te bouwen. Voor de wetenschap is het super interessant om te zien welke materialen kokerjuffers gebruiken om hun huisjes te bouwen. Daarom kan jij zes verschillende type materialen doorgeven. Naast de kokerjuffer met koker is er ook een kokerjuffer zonder koker. Ondanks dat de naam ‘kokerjuffer’ doet vermoeden dat elke soort kokerjuffer een koker bouwt\, zijn er ook kokerjuffers zonder koker\, ook wel naakte kokerjuffers genoemd. Het leven van kokerjuffers begint als een pakketje met eitjes die door de schietmot wordt afgezet in of in de buurt van water. Deze eitjes ontwikkelen zich tot larven\, de kokerjuffers. \nKokerjuffers voeden zich met algen\, bladeren\, watervlooien of andere waterdiertjes. Ze vervellen vier keer voordat ze volgroeid zijn en hun huisje afsluiten met spinsel en materialen. Vervolgens verpoppen ze zich in drie tot vier weken. Na een paar weken is de pop een schietmot geworden. Het diertje bevrijdt zich uit de koker en vliegt er vandoor. Door zijn koker gaat hij helemaal op in zijn omgeving en is het moeilijk voor vijanden om hem te spotten. Kokerjuffers vervellen vier keer voordat ze hun huisje afsluiten met spinsel en materialen. Vervolgens verpoppen ze binnen drie tot vier weken. Na deze transformatieperiode verschijnt de kokerjuffer als een schietmot\, die zich uit zijn koker bevrijdt en wegvliegt. Wil je bijdragen aan het in kaart brengen van de biodiversiteit van wateren en leren over de vele fascinerende waterdieren in Nederland\, waaronder de kokerjuffer? Doe dan mee en ga naar waterdiertjes.nl om je waarnemingen door te geven. \nLinks:\n2024: jaar van de kokerjuffer

SUMMARY:#CERN70
DESCRIPTION:2024 holds special significance for the European Organization for Nuclear Research (CERN) (/sɜːrn/; French pronunciation: [sɛʁn]; Conseil européen pour la Recherche nucléaire)\, as the Organization celebrates its 70th anniversary on 29 September 2024. \nCERN is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954\, it is based in Meyrin\, western suburb of Geneva\, on the France–Switzerland border. It comprises 23 member states. Israel\, admitted in 2013\, is the only non-European full member. CERN is an official United Nations General Assembly observer. The acronym CERN is also used to refer to the laboratory; in 2019\, it had 2\,660 scientific\, technical\, and administrative staff members\, and hosted about 12\,400 users from institutions in more than 70 countries. CERN’s main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research – consequently\, numerous experiments have been constructed at CERN through international collaborations. CERN is the site of the Large Hadron Collider (LHC)\, the world’s largest and highest-energy particle collider. The main site at Meyrin hosts a large computing facility\, which is primarily used to store and analyze data from experiments\, as well as simulate events. As researchers require remote access to these facilities\, the lab has historically been a major wide area network hub. CERN is also the birthplace of the World Wide Web. \nLinks:\nCERN70 \nSpecial anniversary edition of CERN Courier magazine \nExperimenteren met ongrijpbare antimateriedeeltjes – Op bezoek bij de antimateriefabriek van CERN

SUMMARY:Sudan Road Access: Logistics Cluster : Help humanitarians deliver aid in Sudan - Citizen science
DESCRIPTION:The Zooniverse’s Planetary Response Network needs your help to map floods in the Sudan — check out this project: Sudan Road Access: Logistics Cluster. \nThe Zooniverse’s Planetary Response Network is partnering with Logistics Cluster\, which is part of the cluster system established by the UN’s Inter Agency Standing Commitee. Logistics Cluster is helping to coordinate humanitarian aid work in Sudan\, and one of the biggest barriers they face is flooding during about half the year. Sudan is criss-crossed by dry riverbeds that are not yet well mapped\, and during the rainy season they intermittently and unpredictably flood the network of roads used by humanitarian organizations to deliver key supplies and aid across remote regions. Our first task is to complete the map of road-riverbed crossings over the large area of interest for humanitarian aid in Sudan. Once we have a full map of all the potential flood sites\, we will know where to focus our monitoring efforts during the rainy season\, which is just starting. Sudan is big\, so we need your help to find dry riverbeds (called “wadis”) along roads and measure the size of the crossings. \nLinks:\nSudan Road Access: Logistics Cluster \nSudan Logistics Cluster

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:Fentale Volcano - signs of possible eruption 2024 - 2025
DESCRIPTION:Starting from late September 2024\, Ethiopia has experienced series of earthquakes ranging from 4.8 to 5.8 Richter magnitude scale with initial epicenter from Afar Region‘s Awash Fentale and spread across much of central Ethiopia. \nOn 6 October 2024\, a series of earthquakes with 4.9-magnitude tremor occurred starting to Afar Region‘s Awash Fentale area and spread into Oromia Region\, causing widespread concern. The epicenter was about 23 km northeast of Awash as the tremor occurred at the depth of 10 km and the shaking was felt across central Ethiopia. Over 30 homes collapsed in Afar while thousands fled to neighboring area as refuge. Pubic officials responded by shutdown of transportation infrastructure in the tremor zone to investigate the damage and power outages were likely to be measured. On 13 October\, a magnitude of 4.6 quake happened in Oromia Region at around 07:37. The shaking affected throughout central and eastern Ethiopia\, such as southern Afar\, southern Amhara\, and central Oromia regions\, northwestern Somali Region\, and the capital Addis Ababa. Also on 16 October\, an earthquake was observed in Metehara area in Oromia at 23:11 local time with 4.8 magnitude registered. The Volcano Discovery discovered that the tremor struck at the shallow depth of 10 km beneath the Earth surface. The German Research Centre for Geosciences (GFZ) was the first to detail seismic event\, providing crucial data for understanding its effects. According to initial reports\, residents nearby the epicenter were likely saw a quake\, though caused minimal damage. \nOn 29 December\, an earthquake reoccurred in afternoon and until in the morning 5.1 magnitude. Prior to this\, two earthquakes occurred in a week. In January 2025\, 10 earthquakes were recorded within 24 hours in a week. According to the US Geological Survey\, these multiple quakes were 4.3 to 5.1 on the Richter scale occurred around Fentale volcano in Awash. Since 3 January 2025\, signs of a volcanic eruption began to appear\, prompting authorities to move residents to temporary shelters. The Ethiopian Geological Institute posted a video in Facebook page depicting dust and smoke emerging from a volcano in Awash Fentale in Afar region. On that day\, another quake strike with the magnitude 5.8 in epicenter of Addis Ababa. It was at a shallow depth of 10 km according the US Geological Survey and the German Research Centre for Geosciences. \nLinks:\n“Ethiopia rocked by series of earthquakes in 24 hours”. The East African. \n“Ethiopia: Over 30 Homes Collapse in Afar As Earthquakes Intensify in Awash Fentale”. Addis Standard.  \n“Ethiopia: A magnitude-4.9 earthquake occurs in the Oromia Region Oct. 6”. Ethiopia: A magnitude-4.9 earthquake occurs in the Oromia Region Oct. 6 | Crisis24.  \n“Ethiopia: Over 30 Homes Collapse in Afar As Earthquakes Intensify in Awash Fentale”. Addis Standard.  \n“Ethiopia: A magnitude-4.9 earthquake occurs in the Oromia Region Oct. 6”. Ethiopia: A magnitude-4.9 earthquake occurs in the Oromia Region Oct. 6 | Crisis24.  \n“Ethiopia: Magnitude-4.6 offshore earthquake occurs south of Awash\, Afar Region\, at around 07:37 Oct. 13”. Ethiopia: Magnitude-4.6 offshore earthquake occurs south of Awash\, Afar Region\, at around 07:37 Oct. 13 | Crisis24.  \n“Earthquake Shakes Oromiya\, Ethiopia: Residents Feel Tremors In Addis Ababa”. ebc.et.  \n“Earthquake hits Awash Fentale Area again”. Borkena Ethiopian News \n“Ethiopia rocked by series of earthquakes in 24 hours”. The EastAfrican. 2025-01-03.  \n“Risk of Ethiopian volcano eruption prompts evacuation of residents”. Al Arabiya English. 2025-01-03.  \n“Volcanic eruption hits central Ethiopia’s Afar region amid frequent tremors”. www.aa.com.tr.  \n“Earthquake of magnitude 5.8 strikes Ethiopia”. Deccan Herald.

SUMMARY:Evolutie Dag / The Origin of Species – publicatie (1859) 2024
DESCRIPTION:De oorsprong der soorten of Het ontstaan van soorten (Engels: The Origin of Species) (volledig: Over het ontstaan van soorten door natuurlijke selectie of het behoud van bevoordeelde rassen in de strijd om leven)\, waarvan de eerste druk op 24 november 1859 verscheen\, is het bekendste boek van de Britse bioloog Charles Darwin. \nIn het boek zet Darwin zijn evolutietheorie uiteen. Die stelt dat al het leven op aarde een gemeenschappelijke afstamming heeft\, en dat natuurlijke selectie het belangrijkste mechanisme is voor de evolutie van soorten. \nLinks:\nDarwin – Het ontstaan der soorten (1860) \nDarwin Dag / Darwin Day / Charles Darwin geboortedag (1809) \nDarwin-Manuskripe verschwunden
