BioTorsdag: Parasitoider – Aliens, men på ordentlig! UiO Realfagsbiblioteket 2024-10-15 | Velkommen til foredrag ved universitetslektor Petter Bøckman fra Naturhistorisk museum. I anledning halloween skal Petter snakke om parasitter som dreper verten. Vi lover småskummel stemning. Er du en av dem som har hatt mareritt om monsteret fra "Alien", men trøster deg med at dette bare skjer i skumle filmer? Da har vi dårlige nyheter. Dessverre er den biologiske virkeligheten vel så drøy. Parasitter utnytter verten sin i et mer eller mindre langvarig forhold, men tar sjelden livet av verten sin. Parasittoiden derimot, dreper eller steriliserer verten idet den utvikler seg til neste livsstadium. Velkommen til parasittodenes verden!_____________________________Arrangementet er åpent for alle, og det vil bli servert kaffe og te.

GeoOnsdag: Drones, a unique perspective on features of the natural world UiO Realfagsbiblioteket 2024-10-15 | Welcome to the talk "Drones, a unique perspective on features of the natural world", by senior engineer at Department of Geosciences Luc Girod.Gathering data is an essential step in any scientific research. In geosciences, we mostly do that either through in-situ fieldwork, or through satellite remote sensing. These two methods leave a gap in either ground coverage or ground resolution, that drone based data acquisition neatly fills: square kilometer scale, centimeter resolution. This allows the study of landscape features in a way that was simply impossible before. In this talk, we will explore a number of field campaigns performed in partnership with the recently founded DroneLab@UiO, highlighting the various capabilities of the equipment that was deployed, from photogrammetry cameras, to LiDAR and thermal imagery systems.Luc Girod has been employed at the University of Oslo for over a decade, first as a PhD candidate focusing on the use of photogrammetry in cryospheric sciences, then as a Senior Engineer in charge of remote sensing and surveying data processing, and is now leading the activities of the DroneLab@UiO.___________________________Once a month, researchers at the Department of Geosciences, University of Oslo, will tell about their research and introduce the geociences to a wide audience, from first-year undergraduates, colleagues to interested in general. It is possible to ask questions after the lectures. Coffee/tea are served. Everyone is welcome!https://www.ub.uio.no/english/courses-events/events/mednat/ureal/2024/241023geowednesday.html

GeoOnsdag: Bringing rocks from Mars to Earth – why, how and are we ready for it? UiO Realfagsbiblioteket 2024-09-25 | Welcome to the talk Bringing rocks from Mars to Earth – why, how and are we ready for it?, by geologist and planetary scientist at Department of Geosciences Agata Krzesinska.We live in exciting times for space exploration when one of Humanity's most ambitious desires is becoming reality. Since February 2021, the Perseverance rover has been exploring Mars, analysing rocks and searching for evidence of past or present martian life hidden in geological record. Unlike previous rovers, Perseverance is drilling into the martian surface to prepare small samples for the first-ever return to Earth. These samples will enable scientists to study Mars in ways previously unimaginable... But it is a long way ahead before we are sure we are ready to work with them.Agata Krzesinska is a geologist and planetary scientist at the University of Oslo. She specializes in studies of meteorites that give insights into Earth's formation and early evolution. Her research includes examining martian meteorites to understand the formation of martian volcanoes and the presence of water on Mars. She currently serves on a NASA-ESA committee tasked to define an optimized sequence of scientific investigations on the future returned martian samples. Additionally, she curates a collection of terrestrial rocks analogous to those to-be-returned from Mars, which is crucial to run engineering and technology tests.___________________________Once a month, researchers at the Department of Geosciences, University of Oslo, will tell about their research and introduce the geociences to a wide audience, from first-year undergraduates, colleagues to interested in general.

Kepler Seminars: Survivorship Bias and the Diversity of Planets UiO Realfagsbiblioteket 2024-08-30 | By Erik Asphaug Professor, Lunar and Planetary Laboratory, University of ArizonaThe main asteroid belt between Mars and Jupiter is phenomenally diverse, and is sparse by factors of thousands compared to the primordial population thought to have existed there. These aspects are probably related. The largest asteroids are too massive to have been catastrophically destroyed by later impacts, which has led to theories for a fossilized system of bodies that grew rapidly by some form of primary growth, and then was scattered by planetary migration. But this framework is insufficient to explain the diameters of the largest asteroids, their distribution of rotation rates, their striking diversity, and the petrological complexities of meteorites. These are better explained if the main belt, or the inner solar system at large, underwent a concluding epoch of hierarchical, pairwise mergers that lasted a few Myr until planet formation stirred up the relative velocities beyond the accretion threshold. Even in the slowest encounters, only about half of binary collisions are effective mergers; the other half are "hit and run" collisions of various kinds. As planetesimals merge and attempt to merge, this creates a powerful survivorship bias among the unaccreted. To be accreted is the common outcome, but removes those bodies from the sample, whereas avoiding accretion happens in multitudinous ways (the "Anna Karenina principle"). I apply stochastic representations of this process to make predictions for the diversity of final bodies as a decreasing function of their mass, and show that the main belt asteroids are consistent with this mode of formation, followed by dynamical depletion. These models also provide a framework for understanding the exhumation of iron and stony-iron meteorites from deep inside of planetesimals, and potentially the origin of chondrules. I will discuss asteroid (16) Psyche in this context, the 220-km metallic target of the NASA Psyche mission that is enroute. To stimulate conversation I will argue that the diversity of terrestrial planets around the Sun is similarly related to its sparsity compared to the tightly-packed exoplanetary systems that are so common, and that a "late stage" hierarchy of formation, as ended here with the origin of the Moon, is essential to complex life.https://www.mn.uio.no/phab/english/news-and-events/events/kepler-seminars/2024_autumn/erik-asphaug.html
Kepler Seminars: How anomalies drive scientific discovery UiO Realfagsbiblioteket 2024-05-31 | Moving beyond definitions in the search for extraterrestrial life by Carol Cleland, Professor of Philosophy, University of Colorado BoulderIt is often claimed that astrobiologists need a definition of life in order to search for extraterrestrial life: How else can one recognize alien life if one is fortunate enough to encounter it? Yet, as I briefly discuss, definitional approaches face serious logical problems. This talk explores an alternative strategy for searching for extraterrestrial life: Search for potentially biological anomalies (as opposed to life per se) using tentative (vs. defining) criteria. The function of tentative criteria is not, like that of defining criteria, to decide the question of life. Instead, it is to identify phenomena that are especially difficult to classify as living or nonliving as worthy of further scientific investigation for the possibility of novel life. While the proposed strategy resembles that of current life-detection missions, insofar as it advocates the use of a variety of lines of evidence (biosignatures), it differs from these approaches (including so-called “agnostic” biosignatures) in ways that increase the likelihood of noticing truly novel forms of life, as opposed to dismissing them as just another poorly understood abiotic phenomenon. Last but not least, the strategy under consideration would be just as effective at detecting forms of life closely resembling our own as a definition of life.https://www.mn.uio.no/phab/english/news-and-events/events/kepler-seminars/2024_spring/carol-cleland.html
dScience Lunch Seminar: Capitalizing on Norwegian health registry data UiO Realfagsbiblioteket 2024-05-23 | Welcome to our dScience lunch seminar in the Science Library with Hedvig Nordeng.PresentationNorway is home to some of the world's most comprehensive and well-maintained health care registries. These registries contain valuable data on patient demographics, diagnoses, treatments, and outcomes, and as demonstrated during the pandemic, represent a great opportunity for researchers to gain insight into the effectiveness and safety of pharmaceuticals for patients in real-world settings.The Pharmacoepidemiology and Drug Safety Research (PharmaSafe) group, led by Professor Hedvig Nordeng at the Dpt. Pharmacy, MN Faculty, UiO has over fifteen years’ experience working with Norwegian health care data. They have built expertise in linking and analyzing data from health care registries and national cohorts to perform real-world, observational studies on use and safety of pharmaceuticals, especially among vulnerable patients. Over the past years, they have put great efforts into creating a data analytical pipeline at the University of Oslo for rapid analysis of urgent pharmacovigilance signals. Multidisciplinary collaboration across UiO departments, especially with researchers at IFI and the IT department (e.g., TSD) has been essential in this achievement.In this presentation, Professor Hedvig Nordeng will share their experience with developing data analytical pipelines for Norwegian linked health registry data using different Common Data Models (e.g., OMOP, Nordic CDM, ConcePTION) to answer public health questions about use and safety of pharmaceuticals. The Data Analysis and Real World Interrogation Network (DARWIN EU®) project will be presented.SpeakerHedvig Nordeng is a Professor at the Section for Pharmaceutics and Social Pharmacy at the University of Oslo. She has a PhD in pharmacoepidemiology and pharmacotherapy on drug use during pregnancy, Faculty of Medicine, University of Oslo in 2005. Her expertise is in perinatal pharmacoepidemiology and pharmacotherapy in pregnancy and lactation.

GeoOnsdag: Mammuten – Istidens kjempe UiO Realfagsbiblioteket 2024-05-08 | Velkommen til GeoOnsdag. Denne gangen får vi foredrag fra Johan Petter Nystuen, professor emeritus i geologi ved Institutt for geofag, Universitetet i Oslo. Den ullhårete mammuten, Mammuthus primigenius, karakteriserte kvartærtidens megafauna på den nordlige del av den nordlige halvkule de siste 400 000 år, fram til slutten av siste istid. Den siste mammuten døde ut på Vrangeløya i nord-østre Sibir for omkring 4000 år siden. Mammuten, en slekt i elefantfamilien, har sin opprinnelse i Namibia. Den vandret ut av Afrika for 4 millioner år siden og gjennomgikk videre evolusjon i Eurasia og Nord-Amerika, under stadig kaldere klima og endringer i vegetasjon og landskap. Den ullhårete mammuten var tilpasset ekstrem kulde. Dens kinntenner, molarer, var spesialisert for tygging av gress og urter som vokste på en enorm steppe, mammutsteppen, i Eurasia og Nord-Amerika. Mammuten levde sammen med en rekke andre store planteetere og rovdyr, i et komplisert økologisk system. Mennesket begynte med jakt på store dyr da Homo erectus vandret ut fra Afrika for ca. 1,8 millioner år siden. Neandertalerne jaktet på mammut fra omkring 400 000 år siden og fram til for ca. 40 000 år siden, da neandertalerne døde ut. Det moderne menneske, Homo sapiens, jaktet på ullhåret mammut fra omkring 45 000 år siden. Forskning de siste ti år viser at mammuten og mange av de andre store dyrene i dets følge døde ut, ikke primært på grunn av jakt, men først og fremst på grunn av de meget raske klimaendringene ved slutten av siste istid, for omkring 18 000 – 10 000 år siden. Habitatene ble endret, splittet opp, eller forsvant helt. Det gjøres forsøk på å gjenskape mammutsteppen og å lage en «mammofant», en hybrid mellom indisk elefant og mammut.Johan Petter Nystuen er professor emeritus i geologi ved Institutt for geofag, Universitetet i Oslo. Han har erfaring i flere geologiske fagdisipliner, spesielt innen geologisk utviklingshistorie, med studier i Norge, Grønland, Svalbard, USA, Spania og Portugal. Hans doktorgrad (1983) hadde hovedvekt på den neoproterozoiske «Snowball-Earth» istiden i Skandinavia. Nystuen har undervist i allmenn og historisk geologi ved Norges landbrukshøyskole (nå NMBU) og i sedimentologi og sekvensstratigrafi ved UiO, her han har veiledet master- og PhD-studenter. Foruten vitenskapelige publikasjoner har Nystuen forfattet bidrag til flere populærvitenskapelige bøker, nå sist i 2023 med boka «Mammut og menneske – En reise gjennom 66 millioner år», sammen med Ole Nashoug. Om GeoOnsdagEn gang i måneden vil forskere i geofag ved UiO fortelle om sin forskning og introdusere geofagene til et vidt publikum, fra førsteårs bachelor-studenter til nysgjerrige kolleger på universitetet, i en hyggelig atmosfære på Realfagsbiblioteket.

Rosseland lecture 2024: Novelties in Stellar Evolution: Asteroseismology of Fast Rotators UiO Realfagsbiblioteket 2024-04-25 | Each spring, near the date of Svein Rosseland's birthday, the Institute of Theoretical Astrophysics invites everyone to a guest lecture by an internationally renowned astrophysicist as a remembrance for our great astrophysicist Svein Rosseland (1894-1985), founder of our institute.Novelties in Stellar Evolution: Asteroseismology of Fast RotatorsSpace asteroseismology - the study of waves inside stars from high-precision space data - saw its birth less than two decades ago, yet has already revolutionized the theory of stellar structure and evolution. In this talk, 2022 Kavli laureate Conny Aerts will introduce the basic principles of asteroseismology and explain its capacity to probe the internal physics and chemistry of stars. She will highlight how various forces acting upon the stellar gas imply waves of different nature and probing power, covering a wide range of wave frequencies. Applications to sun-like stars and red giants are meanwhile standard practise and briefly discussed. The second part of the talk focuses on applications to stars of intermediate and high mass, which tend to be fast rotators. We discuss how gravito-inertial modes lead to estimates of the internal rotation and chemical mixing in the deep interior of the stars. We illustrate how gravito-inertial asteroseismology triggers opportunities for better stellar evolution models. We end with exciting opportunities for this booming research field of astrophysics, from data-driven modelling based on the integrated exploitation of the ongoing NASA TESS and future ESA PLATO space missions, Gaia astrometry, and ground-based spectroscopic surveys.The Rosseland Lecturer 2024This year’s Rosseland Lecture will be held by Professor Conny Aerts from the Institute of Astronomy, KU Leuven (Belgium)Conny's research covers stellar astrophysics, including stellar structure & evolution and variable stars. She is a pioneer of asteroseismology, which received a major boost thanks to the CoRoT (2006+), Kepler (2009+), and TESS (2018+) space missions. Prior to high-precision space photometry, Conny developed rigorous mathematical methods to detect and identify non-radial stellar oscillations in high-resolution time-series spectroscopy. Her team also designed and applied statistical classification methods in a machine-learning context, discovering numerous gravity-mode pulsators in space photometry. As Chair in Asteroseismology at the Radboud University Nijmegen, Conny introduced herself into the topic of subdwarf stars, their binarity and pulsations, with current focus on development and exploitation of BlackGEM in tandem with gravitational wave studies.

GeoOnsdag: Tining av permafrost og tilbakekoblinger til det globale klimaet UiO Realfagsbiblioteket 2024-04-10 | Velkommen til GeoOnsdag. Denne gangen får vi foredrag fra førsteamanuensis Sebastian Westermann, Institutt for geofag, UiO. Permafrostjord inneholder store mengder organisk karbon som har samlet seg i den frosne bakken i årtusener. Når permafrosten tiner på grunn av klimaendringene, kan mikrober bryte ned dette organiske materialet, noe som kan frigjøre ytterligere klimagasser til atmosfæren. Til tross for en betydelig forskningsinnsats det siste tiåret, er de nåværende modellprognosene for denne "permafrost-karbon-tilbakekoblingen" dårlige.Presentasjonen gir en oversikt over dagens kunnskap om permafrost og karbonkretsløpet i permafrosten. Vi rapporterer også om pågående forskningsaktiviteter ved Senter for biogeokjemi i antropocen (CBA) og Institutt for geofag, fra satellittbasert kartlegging av den globale permafrosttilstanden til undersøkelser av karbonsyklusen i palsmyrer i Nord-Norge.Sebastian Westermann er førsteamanuensis ved Institutt for geofag og CBA. Han arbeider med modellering, fjernmåling og feltmålinger av permafrost, spesielt i Nord-Norge, Svalbard og Mongolia.Om GeoOnsdagEn gang i måneden vil forskere i geofag ved UiO fortelle om sin forskning og introdusere geofagene til et vidt publikum, fra førsteårs bachelor-studenter til nysgjerrige kolleger på universitetet, i en hyggelig atmosfære på Realfagsbiblioteket.

GeoOnsdag: Havstrømmene i nord: Noen uløste mysterier UiO Realfagsbiblioteket 2024-03-14 | Velkommen til GeoOnsdag. Denne gangen får vi foredrag fra professor Pål Erik Isachsen ved Institutt for geofag, UiO. Havstrømmene i nord er viktige for Norge og verden, både fordi de transporterer næringsstoffer rundt i det rike marine økosystemet utenfor kysten vår og fordi de er med på å regulere klimaet på jorda. I dette foredraget dykker vi innom begge aspektene. Vi zoomer først inn på småskala-strømmer rundt Lofoten og Vesterålen, for å se på hvordan de påvirker det tidlige livsløpet til torskeyngelen som klekkes i Vestfjorden. Deretter zoomer vi ut og ser på hvordan de store havstrømmene i Arktis oppfører seg ganske anderledes enn strømmer lengre sør på planeten. I begge tilfeller blir det tydelig hvor viktig bunntopografien---formen på havets bunn---er for å styre det som skjer. Men over hundre år etter Helland-Hansen og Nansens første studier av havsirkulasjonen i nord gjenstår ennå store mysterier.Pål Erik Isachsen er professor i oseanografi ved Institutt for geofag ved UiO.Om GeoOnsdagEn gang i måneden vil forskere i geofag ved UiO fortelle om sin forskning og introdusere geofagene til et vidt publikum, fra førsteårs bachelor-studenter til nysgjerrige kolleger på universitetet, i en hyggelig atmosfære på Realfagsbiblioteket.

The quest for artificial general intelligence and the limits of science UiO Realfagsbiblioteket 2024-03-08 | Lecture by John Lennox, Professor Emeritus of Mathematics at the University of Oxford and Emeritus Fellow in Mathematics and the Philosophy of Science at Green Templeton College, Oxford. We humans are insatiably curious, and have always been asking questions, such as the hard questions about origin and destiny. With the rise of artificial intelligence, these questions have become even more daunting. On the one hand, we live in a time of rapid scientific progress that holds enormous promise for many of the problems we face as humankind. So much so, in fact, that many see no need or use for other ways of solving the mysteries of our universe. They assume that science can explain everything. On the other hand, popular answers to questions about artificial general intelligence differ wildly: from utopian vistas of superhumans working alongside superintelligent Al to Orwellian outcomes where humans are controlled or outcompeted by superintelligent machines or superior versions of themselves.Lennox argues that the ethical considerations that we bring to bear on these questions is worldview dependent and has serious implications for our thinking about the future of humanity.John Lennox, Emeritus Professor of Mathematics at the University of Oxford and Emeritus Fellow in Mathematics and Philosophy of Science at Green Templeton College has written many books on religion, ethics, and the relationship between science and God and has had public debates with atheists including Richard Dawkins and Christopher Hitchens. Lennox will be interviewed by Sverre Holm, Professor of Physics, and the topic is taken from Lennox’ two books “2084: Artificial Intelligence and the Future of Humanity” (2020) and “Can science explain everything?” (2019). https://www.ub.uio.no/english/courses-events/events/mednat/ureal/2024/240307lennox.html
Kepler Seminars: Chicxulub, Deccan, Tanis, and the Demise of T. rex and Friends UiO Realfagsbiblioteket 2024-03-01 | Chicxulub, Deccan, Tanis, and the Demise of T. rex and Friends by Mark Richards, Professor of Earth and Space Sciences at the University of Washington in Seattle.The Deccan Traps flood basalt eruptions were approximately time-coincident with the Chicxulub impact in Yucatan, Mexico, which was likely the main cause of the end-Cretaceous (K-Pg) mass extinction that exterminated the non-avian dinosaurs at about 66 Ma. The Deccan eruptions were well underway at K-Pg time, but geological and geochronological evidence suggests that the magnitude Mw ~11 earthquake due to Chicxulub may have accelerated the Deccan eruptions at exactly K-Pg time. Although it is unlikely that outgassing associated with the Deccan eruptions was primarily responsible for the mass extinction, it is possible that these eruptions contributed to the climate disturbance that resulted in a prolonged recovery period.Recently, a remarkable paleontological discovery in North Dakota, USA, suggests that seismic waves from the Chicxulub impact also caused a tsunami-like deposit along the existing Western Interior Seaway, capturing literally the last ~2 hours of the Cretaceous (or the first 2 hours of the Paleocene, depending on your point of view) in stroboscopic detail, including freshwater fish ingesting impact spherules from the water column before they were killed by ~10-meter water surges up a large river channel. Modeling and understanding the nature of this event, and likely similar events worldwide, promises to advance our understanding of the K-Pg mass extinction event. The excitation of Deccan eruptions by the Chicxulub impact likewise lacks detailed explanation. In other words, we have new and tantalizing clues as to events at K-Pg time that are perhaps much richer than previously imagined.About:Mark Richards is a professor of Earth and Space Sciences at the University of Washington in Seattle, where he also served the past five years as Provost and Executive Vice President. Prior to this position he was a professor of Earth and Planetary Science at the University of California, Berkeley, where he also served as Dean of Mathematical and Physical Sciences and Executive Dean of the College of Letters and Science. Mark is a geodynamicist who has worked on the large-scale structure of mantle convection and its relation to plate tectonics, as well as the dynamics of mantle plumes and their expressions as flood basalts (such as Deccan) as well as hotspot tracks (such as Hawaii, La Reunion, and Galapagos). His current research includes geological and biological co-evolution in the Galapagos archipelago, continuing work on flood basalt eruptions and events at the K-Pg boundary, as well as modeling glacio-isostatic adjustment processes in North America and Fennoscandia following the most recent Ice Age. He has also made significant contributions to promoting diversity in science and engineering at American research universities.https://www.mn.uio.no/phab/english/news-and-events/events/kepler-seminars/2024_spring/mark-richards.html

GeoOnsdag: Hva kan seismisk overvåkning brukes til? Fra jordskjelvmåling til skredvarsling UiO Realfagsbiblioteket 2024-02-15 | Velkommen til årets første GeoOnsdag. Denne gangen får vi foredrag fra forskningsleder i Stiftelsen NORSAR, Volker Oye, om seismisk overvåkning. NORSAR er en forskningsstiftelse med kjernekompetanse i seismologi og anvendt geofysikk. De gjennomfører forsknings- og rådgivningsprosjekter knyttet til disse fagområdene over hele verden. De bruker deres kompetanse til å løse et bredt spekter av oppgaver. Den viktigste er ivaretakelsen av Prøvestansavtalen (CTBT), der de er ansvarlig for driften av den norske delen av et av verdens mest avanserte overvåkningsanlegg. Dette bruker de til å lytte etter og skille mellom jordskjelv og mulige atomprøvesprengninger. Basert på kunnskapen i jordskjelvmåling, analyse og tolkning videreføres kunnskapen til samfunnsrelaterte anvendelser. I foredraget blir det vist frem eksempler fra deteksjon av sprengninger ved Nordstream pipelines, seismisk overvåkning av situasjonen i Ukraina, bruk av seismisk overvåkning for sikker CO2 lagring og anvendelser for skredvarsel. Volker Oye er forskningsleder i Stiftelsen NORSAR og leder avdelingen for anvendt seismologi. Oye er seismolog og har jobbet mest med små jordskjelv, altså jordskjelv som ikke er følt av mennesker. Forskningsfeltet som er mest interessant her er å skille mellom naturlige og menneskeskapte jordskjelv.Om GeoOnsdagEn gang i måneden vil forskere i geofag ved UiO fortelle om sin forskning og introdusere geofagene til et vidt publikum, fra førsteårs bachelor-studenter til nysgjerrige kolleger på universitetet, i en hyggelig atmosfære på Realfagsbiblioteket.

Kepler Seminars: Formation of Archean continental crust UiO Realfagsbiblioteket 2024-02-02 | Formation of Archean continental crust by Nicholas (Nick) Arndt, Emeritus Professor ISTerre, University Grenoble AlpesThe process that generated the continental crust has long been debated. One school argues that, through most of geological time, the crust formed at convergent margins like most modern granitoids. The other school promotes a model in which, from the Hadean to at least 2.5–3.0 Ga, the continental crust grew within a stagnant or sporadically mobile lid. In one version of this model, the lower part of thick mafic crust partially melts to produce felsic magma. In another, a process called sagduction operates: the lower part of a thick pile of mafic rocks converts to eclogite, sinks into the mantle, and partially melts to form the felsic magmas that build the continental crust.In this paper, I argue that the latter processes are implausible. The lower part of thick oceanic crust consists of ultramafic cumulates and these rocks are dry. Missing is basalt and water, both of which are needed to produce granitic melt. Hydrated volcanic rocks never are deeply buried, and any water released during their dehydration migrates upwards into cooler rocks where it cannot trigger partial melting.Subduction probably operated on Earth from at least 3.8 Ga. Archean subduction zones may have been shallow, short-lived and transient but they were capable of transporting hydrated oceanic crust to depths of 100 km, which is all that is needed for the formation of granitoid magmas. The presence of subduction zones does not necessary imply the operation of plate tectonics. A hybrid situation is possible in which a mobile or partially mobile lid covered most of the planet, but localized, shallow, transient subduction zones operated to generate the felsic magmas that built the continental crust.All the changes that are said to signal a major change in geodynamic regime around 3 Ga are better explained as the nexus of several ongoing processes: (1) progressive growth of felsic crust, particularly during major mantle-generated pulses at 2.7 and 2.5 Ga; (2) the emergence of land that allowed erosion and generation of detrital sediments; and (3) a decline of temperatures in mantle and crust, which changed the style of intracrustal deformation.https://www.mn.uio.no/phab/english/news-and-events/events/kepler-seminars/2024_spring/nick-arndt.html
BioTorsdag: A small peptide that could save the horseshoe crab UiO Realfagsbiblioteket 2024-01-26 | Welcome to 2024's first BioTorsdag! This time, Professor Dirk Linke at the Department of Biosciences will unravel the intricate relationship between molecular biology, medicine, and the conservation of biodiversity.Our research group tries to understand bacterial adhesion.As part of our work on the molecules that mediate adhesion to host cells and to medical implants, we serendipitously identified a peptide that can bind lipopolysaccharides with extremely high affinity.Lipopolysaccharides (LPS) act as endotoxins, and are key molecules in causing septic shock - "blood poisoning". Our peptide might be useful in developing sensitive assays for endotoxin detection, and for removing endotoxins from biopharmaceutical production pipelines or even from patient blood.In this lecture, I will describe how this connects to the horseshoe crab, a living fossil and endangered species.https://www.ub.uio.no/english/courses-events/events/mednat/ureal/2024/bio-thursday-2024-01-24.html
BioTorsdag: Antibiotika i dyrefôr - kan det påvirke vår helse? UiO Realfagsbiblioteket 2023-11-30 | Velkommen til semesterets siste BioTorsdag. Denne gang er det instituttleder Roger Simm ved Institutt for biovitenskap som skal snakke om i hvilken grad bruk av antibiotika i dyrefôr påvirker antibiotikaresistens hos mennesker. Antibiotikaresistens er et økende problem i hele verden og en stor trussel mot moderne medisin og menneskets helse. Resistente bakterier finnes overalt i mennesker, dyr og miljøet, men ansees oftest ikke å være et problem før de forårsaker sykdom som ikke kan behandles hos mennesker. Hvordan utvikles og spres resistens blant bakterier? Kan resistente bakterier i dyr være en risiko for mennesker? I dette foredraget tar vi utgangspunkt i et forskningsprosjekt som undersøker hvorvidt bruk av fôrtilsetning i kyllingfôr kan øke antallet resistente bakterier, og diskuterer om resistente bakterier i dyr utgjør en trussel mot muligheten for behandling av infeksjoner i mennesker, og om det finnes måter å forhindre dette på._____________________________Arrangementet er åpent for alle, og det vil bli servert kaffe og te.

GeoWednesday: No Seal, no deal UiO Realfagsbiblioteket 2023-10-18 | Geological storage of CO2 in saline aquifers or depleted oil/gas reservoirs is a paramount solution to reduce human-induced CO2 emissions into the atmosphere. Many nations are planning large-scale CO2 storage projects worldwide to follow the Paris Accords to keep global warming below 1.5 to 20C. Seal or caprock quality is highly critical for any safe and successful CO2 storage. This presentation will focus on seal quality assessment of potential CO2 storage in 3 exploitation licenses EL001 (Aurora), EL002 (Smeaheia) and EL004 (Luna), in the Troll area, offshore Norway. The ultimate goal is to show how the seal units of saline aquifers and depleted hydrocarbon reservoirs are characterised using multi-disciplinary techniques of geology, geophysics, petrophysics, rock physics, geomechanics and machine learning.___________________________Once a month, researchers at the Department of Geosciences, University of Oslo, will tell about their research and introduce the geociences to a wide audience, from first-year undergraduates, colleagues to interested in general.

What path leads us through the 13.8-billion-year history of the Universe, connecting the particles and energy of the Big Bang to the formation of galaxies like the Milky Way, stars like the Sun and planets like the Earth?The James Webb Space Telescope, built by NASA in partnership with the European and Canadian Space Agencies, was designed to answer fundamental questions about the origins of galaxies, stars and planets, and to help us find our place in the Universe. Webb was launched on Christmas Day 2021 after 25 years of planning, design, development, construction, and testing.Following a six-month deployment and commissioning period, the first science results from Webb have engaged the public and surprised the scientists. Webb’s science goals address our origins and the history of the universe: the first stars and galaxies that formed after the Big Bang; the sizes, shapes, and components of galaxies as they evolve; the formation of stars and planetary systems; and exoplanets, the history of our own Solar System, and the conditions for life on other planets. In its first year of scientific operations, Webb has already found the most distant galaxies ever seen.The light from these galaxies has been traveling for 13.5 billion years of the 13.8 billion years since the Big Bang, allowing us to study early galaxies that formed under very different conditions than we see today. Webb has made the first detection of carbon dioxide in the atmosphere of an exoplanet and has examined the interactions between giant stars and the planets that are forming near them. I will review Webb’s construction, launch, and deployments, and discuss the commissioning of the telescope and its instruments.https://www.ub.uio.no/english/courses-events/events/mednat/ureal/2023/210923physicsatthelibrary.html
Klimafølsomheten: Det store spørsmålet i klimaforskningen UiO Realfagsbiblioteket 2023-09-20 | Velkommen til semesterets første GeoOnsdag. I denne utgaven er det professor Terje Koren Berntsen fra Institutt for geovitenskap ved Universitetet i Oslo som skal holde foredrag.Hvis verdenssamfunnet skal oppfylle målet i Parisavtalen om å begrense oppvarmingen til 1.5 grader, må politikerne få vite hvor mye utslippene totalt må reduseres og hvor raskt. Fordi endringene i klima fra våre utslipp påvirker hele systemet (slik som skyer, vanndamp, havstrømmer, vegetasjon, snø, is, osv) har det vist seg veldig vanskelig å beregne dette nøyaktig. Foredraget gir en oversikt over hvordan moderne klimaforskning prøver å forbedre dette ved bruk av observasjoner og klimamodeller.Om GeoOnsdagEn gang i måneden vil forskere i geofag ved UiO fortelle om sin forskning og introdusere geofagene til et vidt publikum, fra førsteårs bachelor-studenter til nysgjerrige kolleger på universitetet, i en hyggelig atmosfære på Realfagsbiblioteket. Det er mulig å stille spørsmål etter foredraget.https://www.ub.uio.no/kurs-arrangement/arrangementer/mednat/ureal/2023/230020geoonsdag
dScience Lunch Seminar: Large language models under the hood UiO Realfagsbiblioteket 2023-09-07 | Welcome to our dScience lunch seminar in the Science Library, where Andrey Kutuzov will talk about ChatGPT.In the last few years, radical increase in the scale of deep neural language models (both in terms of the size of the training data and the size of the models themselves) has led to impressive achievements in various natural language processing tasks. "Celebrity" models, like ChatGPT, LLaMa, BLOOM or PaLM are already sometimes described to as "approaching artificial intelligence", although the reality can differ from over-hyped media coverage.In this talk, Kutuzov will describe the foundations of the technology behind large-scale language models. Two most important components behind their success are 1) state-of-the-art deep learning architectures (in particular, Transformer) and 2) the availability of tremendous amount of textual data used to train such models. The interaction of these two poses intricate theoretical and practical questions, also linked to issues with unequal distribution of computing resources. Do we have enough good-quality training data for languages other than English? Is "data poisoning" with automatically generated texts is a real danger? Why is it important to open source both training data and model weights?SpeakerAndrey Kutuzov (PhD, UiO, 2020) is an Associate Professor in the Language Technology Group at the University of Oslo. He currently serves as the Norwegian on-site manager of the High-Performance Language Technology (HPLT) project. His academic interests include Computational linguistics and natural language processing, semantic change detection and diachronically aware language models, distributional semantics, machine learning and large-scale language models. In 2022, Kutuzov received the Norwegian Artificial Intelligence Research Consortium (NORA) award as a Distinguished Early Career Researcher.https://www.uio.no/dscience/english/news-and-events/events/23-ls-sep7.html

GeoOnsdag: Mineralreaksjoner under lupen UiO Realfagsbiblioteket 2023-04-12 | Denne gangen får vi foredrag fra førsteamanuensis Kristina Dunkel ved UiO Institutt for geofag om mineralreaksjoner.Når det kommer til mineraler er ikke alt hugget i stein – mineraler er stadig i forandring. Vi skal se hvordan vi kan studere mineralreaksjoner for å lære om historien til Norges nasjonalstein. Du vil også få høre om hva slags mineraler som finnes i vaskepulver og hvorfor, og hvordan gruveavfall fra Røros kan brukes til å ta tak i miljøproblemer. Kristina Dunkel er geolog og førsteamanuensis i metamorf petrologi ved Institutt for geofag (UiO). Hun forsker vanligvis på mineralreaksjoner og -deformasjoner som skjer dypt i jordskorpen, men hun liker å komme opp i ny og ne for å studere reaksjoner som skjer litt nærmere oss menneskene på overflaten.https://www.ub.uio.no/kurs-arrangement/arrangementer/mednat/ureal/2023/230412geoonsdag
