When people and tigers use the same forest, their ability to cope and co-adapt to the influences of the other is much higher than currently understood. This is one of the conclusions drawn by Leiden BioSocial researcher Shekhar Kolipaka, who researched whether tigers can survive in human-dominated…

Leiden astronomer Xander Tielens has been awarded a Spinoza prize, the highest scientific prize in the Netherlands. Tielens is Professor in the Physics and Chemistry of Interstellar Space. He studies large and complex, often organic, molecules found in interstellar space. The Spinoza prize carries a…

The oldest forms of literature and law originate from Mesopotamia (3000 BC until AD 70), as do important discoveries in science and technology. All these developments were recorded in cuneiform texts on clay tablets. There is still a lot to learn from the study of cuneiform texts, says Professor of…

Just about every student wrestles with these questions, and Lisanne and Wilbert are no exception. They called on the help of the University's…

The balance is positive: the faculty is growing faster than expected, reserves have been built up, and new programmes are attracting many students. At the same time, rapid growth requires realistic budgets, targeted staff expansion and agility in changing circumstances.

A plant that takes metal from the ground all by itself: a natural way to mine or to clean the soil. PhD student Roderick Bouman (Hortus Botanicus Leiden) described a new plant species from Sabah, Borneo, which can be used to extract nickel. In an open access article in Botanical studies, he and the…

This is at the heart of immunotherapy, the most promising progress in cancer treatment in recent years. In order to drive this development further, the Netherlands Cancer Institute-Antoni van…

Why have some European countries responded faster to the coronavirus outbreak than others? While in some countries the lockdown had already been declared when relatively few cases were known, others did not take action until thousands of people were already infected and hundreds were already dead. What…

Exactly a century ago, astronomers observed the first two diffuse interstellar bands (DIBs) in space. A DIB manifests itself as a colour of light that is missing in the radiation from stars behind an interstellar cloud. Although about 500 DIBs are yet discovered, they remained inexplicable until recently.…

An international team of astronomers including Leiden scientists publishes the image of a young star with a surrounding dust disk that is still being fed from its surroundings.

Peter Akkermans, Professor of Archaeology of the Middle East, cannot say for certain how much damage the destruction by IS has caused in Palmyra.

Neanderthals were able to make fire on a large scale with the aid of pyrite and hand-axes. This means they could decide when and where they wanted fire and were not dependent on natural fire, as was thought earlier. Archaeologist Andrew Sorensen has discovered the first material evidence for this. Publication…

Skåne University Hospital, Lund University and Leiden University Medical Center will work together to expand their research, teaching and development relating to Advanced Therapy Medicinal Products. That is the essence of a Memorandum of Understanding signed at SciLifeLab near Stockholm on Wednesday…
