A team of researchers from Leiden Institute of Advanced Computer Science (LIACS) recently hosted a big international conference (EMO 2023). At the conference, computer scientists discussed algorithms that are important in areas such as drug discovery, industrial production planning, and sustainable…

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The Institute of Public Administration is located in The Hague.

In otherwise energetic desserts at the bottom of the sea, researchers have found oases where microbes can harvest energy. Remarkably, the microbes first have to be buried under starving conditions for 80,000 years. An international group of researchers, amongst them José Mogollón from the Insitute of…

Predictors of work functioning in persons with multiple sclerosis

Astronomers led by Pieter van Dokkum have discovered a galaxy that barely contains any dark matter, which actually proves that dark matter does indeed exist. The research results will be published this week in Nature.

Monday June 18th the department of European Prehistory of the Faculty of Archaeology started a five-year research (2018-2022) of two newly discovered barrow groups: Baarlo-De Bong and Venlo-Zaarderheiken (northern Limburg).

Harvesting rice from the same field, without planting new rice plants? A discovery may bring this scenario closer. Leiden scientists have discovered a gene that allows annual plants to grow after flowering, instead of dying. Publication on 13 April in Nature Plants.

Controlling fire was a turning point in the development of human civilisation. But how did fire become part of the human toolkit? The BBC radio show CrowdScience discusses the topic with Leiden archaeologists Andrew Sorensen and Kathy MacDonald.

Leiden University researchers have discovered by chance a note from 1783 in Papiamento. They are working on a linguistic study on confiscated Dutch letters. The ‘Letters as loot’ project is headed by Professor Marijke van der Wal.

Research question

Over the past few years, citizen scientists from the Heritage Quest project have scoured the entire Veluwe and Utrechtse Heuvelrug areas for unknown archaeological heritage. One of the results of this research is that the number of known burial mounds in this area has doubled.

Astronomers from the Leiden Observatory and from the University of Rochester (in the US) have discovered that the planetary ring system that covered the very young sun-like star J1407 is actually of enormous proportions. In fact, it’s much larger and heavier than the ring system surrounding Saturn.…

After almost twenty years the record for the most distant radio galaxy has been broken. A team of astronomers led by Leiden PhD candidate Aayush Saxena has discovered a radio galaxy from the time when the universe was just one billion years old. The galaxy is at a distance of 12 billion light years…

In dribs and drabs, first-year students in The Hague are discovering their new student town and the University buildings. We followed a group of Security Studies students during the HOP introduction week.

A marvelous mosaic synagogue floor has been discovered at the Israeli excavation site of Horvat Kur. The timeworn stones of the mosaic clearly form the name ‘El’azar’. Leiden University researcher Jürgen Zangenberg and a group of Leiden students played a role in the excavation. ‘El’azar was likely an…

The number of students at Leiden University in The Hague is growing every year. From 21 to 25 August more than a thousand new students were given an introduction to The Hague during the HOP week. From museums to embassies and from international organisations to a day at the beach: The Hague has it…

The Leiden wall formulae, Einstein's sink or the signature wall of Ehrenfest. It are just a few of Leiden's hidden science treasures. Alumnus from the Leiden Observatory Alex Pietrow described a few of these places on travel website Atlas Obscura.

During the Masterclass “Archaeology from the Sky”, participating students have used small drones to acquire aerial photos from the Italian landscape of Molise. With sometimes amazing results.

A single tiny molecule that can destroy flu, corona, HIV and Zika viruses? Yes, it really does exist. Biophysicist Niek van Hilten, who will receive his doctorate on 14 September, contributed to this discovery.

Psychologist Hilmar Zech found that overweight people are actually more attracted to food pictures after eating than before. He did so using an old research method that he revamped for use on smartphones. Zech will defend his PhD on 30 April.

Scientists have long assumed Neanderthals simply lost the evolutionary race against humans. But their disappearance may be a bit more complex. In Discover Magazine, Gerrit Dusseldorp sheds light on this illusive question.

A team of laboratory astrophysicists from Leiden University managed to make glycerol under conditions comparable to those in dark interstellar clouds. They allowed carbon monoxide ice to react with hydrogen atoms at minus 250 degrees Celsius. The researchers publish their findings in the Astrophysical…

A flake of limestone (ostracon) inscribed with an ancient Egyptian word list of the fifteenth century BC turns out to be the world’s oldest known abecedary.
