Language can be a time machine: we can learn from ancient texts how our ancestors interacted with the world around them. But can language also teach us something about people whose language has been lost? PhD candidate Anthony Jakob investigated whether the languages of prehistoric populations left…

The Netherlands Organisation for Scientific Research has awarded a grant of 750,000 euros to the 'Visualising the Unknown in 17th-century Science and Society' project.

Where does Dutch come from? Newly appointed Professor Alwin Kloekhorst looks for an answer to that question in millennia-old languages from Anatolia, the Asian part of present-day Turkey. 'A new interpretation in one of the Anatolian languages can have consequences for dozens of other languages.'

From lectures by Robbert Dijkgraaf to a telescope on the ocean floor: during his double bachelor’s in Physics and Astronomy, Jelle Oonk discovered that the path to big cosmic answers sometimes runs through the smallest, hardest-to-catch particles—neutrinos.

New publication reviews Dutch colonial sources on the Indigenous Brazilian Tapuia people: ‘For them the Dutch were another piece on the political chess board’

How can we tell whether and how a prehistoric weapon was used? How can we better understand the dexterity and combat skills involved in Bronze Age spear fighting?

Lions in Kenya respond very differently to human land use, climate and conservation practices. That is the conclusion of thesis from Leiden biologist Monica Chege. A uniform approach is therefore insufficient. ‘Effective conservation only works when management is tailored to local conditions and developed…

Hunter-gatherers caused ecosystems to change 125,000 years ago. These are the findings of an interdisciplinary study by archaeologists from Leiden University in collaboration with other researchers.
