Happy Holidays from LACDR

With the help of the JEDI fund, Fatima al Moufridji and Thijs Porck went in search of cultural contacts between early medieval England, Northern Africa, and the Middle East. Together they made four knowledge clips that can now be seen on YouTube.

Psychologen laten zich horen over de plannen om de internationale bacheloropleidingen op te heffen in de Randstad en Tilburg. Het inititatief #Ikbeneenpsycholoog van Judith Schomaker op LinkedIn vindt navolging. Lees een selectie van de posts en ook het blog van Eiko Fried over de consequenties.

An international team of astronomers led by Ardjan Sturm of the Observatory has made the first two-dimensional inventory of ice in a planet-forming disk of dust and gas surrounding a young star. The researches, including Melissa McClure, used the James Webb Space Telescope and publish their findings…

Not only dark matter, but also ordinary matter and dark energy are tracked in the largest ever cosmological computer simulation ever. In the FLAMINGO simulations, you can see virtual galaxies and clusters of galaxies emerging over the course of billions of years. This is no easy task: with more than…

Could water be present in planet-forming disks before the formation of rocky planets? The James Webb Space Telescope may have found evidence for that. Webb has for the first time observed water in the inner disc around young star where at greater distance, giant planets have already formed. The research…

The supermassive black hole at the center of the Circinus galaxy is being fed with gas by two spiral arms. This is what PhD candidate Wout Goesaert discovered. But only a small percentage disappears into the black hole, the rest is ejected.

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star at which planet formation has finished, while the same-aged companion star still has a planet-forming disk. The researchers…

Associate professor Salvador Santino Regilme spoke in various media outlets about the tensions between the United States and Venezuela.

Sufyan Al Karaimeh, a guest researcher at the Faculty of Archaeology, is currently involved in the Aerial Archaeology in Jordan (AAJ) Project. Over the past 25 years, the individuals involved in this project have not only compiled an expansive collection of photographs but have also helped discover…

Researchers need to work in specialized environments when they work with dangerous bacteria and viruses. These microbes spread easily, so only in labs with a high biosafety levels they can be studied. Unfortunately, to look at the microbes properly, expensive microscopes are needed that are not always…

Generative AI such as Chat GPT has been part of our working and learning environment since 2022. This AI use in the educational setting by students, teachers and staff members comes with a number of new challenges. The creative process of writing a "classic paper" for instance, can be carried out partly…

Jus post bellum, the body of laws and norms governing the transition from armed conflict to peace, has emerged as a crucial issue for international law scholars, governments, and all concerned with building a just and sustainable peace. The Jus Post Bellum Project, funded by the NWO and hosted by the…

Jasper Knoester startte op 1 januari als onze nieuwe decaan. Hoe gaat het met hem, wat doet hij precies en hoe ziet zijn dag eruit? In elke nieuwsbrief geeft Jasper een inkijkje in zijn leven als decaan.

In a recent study, Dr. Moji Aghajani and colleagues show that adolescents with a severe form of Conduct Disorder (CD) -with limited prosocial emotions- require an unusually large amount of brain capacity to read emotional faces. These effects were found in comparison to CD youth without limited prosocial…

In a new article in the journal Scientific Reports, Leiden archaeologist Wei Chu and colleagues report on recent excavations in Western Romania at the site of Româneşti, one of the most important sites in southeastern Europe associated with the earliest Homo sapiens. The site gives an important glimpse…

The Indonesian government has been trying to enforce marriage and divorce laws for some time. These efforts are encountering resistance from both local communities and the Indonesian Supreme Court. PhD candidate Al Farabi investigated where this resistance comes from.

A widely publicized research article in Nature Metabolism by scientist from the University of Pittsburgh, suggests a high protein diet which is popular among for instance fitness enthusiasts, may be harmful to the cardiovascular system. National media outlets such as NRC Handelsdagblad and NPO 1 Radio…

In de maanden maart, april en mei organiseerde het programma Transparantie in Informatie, van de ministeries van Economische Zaken en Klimaat (EZK) en Landbouw, Natuur en Voedselkwaliteit (LNV), gesprekken over de veranderopgave naar een Open Departement. De sessies hadden als doel om een eerlijk en…

Buried beneath a Suffolk forest, archaeologists have uncovered the earliest known human-made fire. A fire that was sparked 400,000 years ago. This stunning UK discovery may rewrite our evolutionary story, potentially pushing fire-making back by more than 350,000 years.

Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.

Astronomers led by Leiden PhD candidate Richelle van Capelleveen have, for the first time, discovered an exoplanet that has carved a bright gap in the protoplanetary disc around its star. This rare observation provides new insights into how young planets shape their surroundings.

Ward Hoskens started ten years ago as an intern at one of Leiden's most iconic buildings: the Pieterskerk. Now he is doing his PhD on the question of how the function of this 'church that is no longer a church' changed over recent centuries.

A patent for what may be a potent, new antibiotic. And: a clear overview of promising approaches to overcome a crucial resistance tactic employed by bacteria. In the span of one week, two researchers from Leiden are receiving their PhDs, each of them on an important step in the battle against bacteria…

Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of…

Astronomers led by Simon Portegies Zwart used simulations to reconstruct how three stars were ejected from the star cluster R136, 60,000 years ago. The analysis reveals that five stars were involved in the event in the Tarantula Nebula.

Inspectors at the Dutch Tax and Customs Administration can require people to provide more information relating to their tax returns. Esther Huiskers-Stoop from the Tax Law department investigated the rules in place to protect us when we are required to provide information to the tax authorities.

Dr. Salwa El-Awa delivers a talk on Wednesday, November 2nd, on "Ambiguity in the Qur'an".

The shock wave triggered by one of the five galaxies making up the iconic Stephan’s Quintet appears to be less disruptive than previously thought, with the shock likely being cushioned by dust particles in the surrounding gas. This is according to the analysis of the first scientific observations of…

For the first time, astronomers have observed in three dimensions that gas from spiral galaxies is blown upwards and downwards at high speed, far out of the galaxy. They thereby confirm the theory of galaxy evolution: that star-forming galaxies create intergalactic gas flows by discharging gas along…

The members of the Board of ALTEX Edition, the ALTEX Editorial Board and ALTEX Editorial Office elect the winner of the annual award out of all main articles published in the previous year; articles including members of the Board of ALTEX Edition or ALTEX Editorial Office as first authors are excluded.…

In the days following Christmas, Christa Tobler gave a series of interviews to Swiss newspapers and Swiss radio about the new Trade and Cooperation Agreement between the EU and the UK and about what it might mean for Switzerland-EU relations and the draft EU-Swiss institutional framework agreement.

An international team of scientists, including Xander Tielens of Leiden Observatory, has used space telescope Hubble and the ALMA observatory to show that UV radiation from massive stars can prevent planets from forming. The researchers publish their findings on 1 March in the journal Science.
