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…

Overview of all dissertations published by PhD candidates from CML.

Former dean and physicist Frans Saris writes in his new book ‘Darwin’s combination lock’ how our culture enabled us to dominate nature and about the corresponding responsibilities. Together with Joris Berkhout he will talk about his book during the This Week’s Discoveries on 27 February.

From underground heat exchangers at the Bio Science Park to drinking taps to replace water coolers. With its new environmental policy plan, Leiden University will become greener in the coming years.

Photosynthesis is the origin of life on earth, but it is a phenomenon that is still barely understood. Take, for example, the extremely efficient mechanism of electron transport. Leiden researchers demonstrate for the first time where one particular cause of this might be found.

The Sustainable City Lab The Hague will be a hub that connects organisations in The Hague that work on sustainability with the research and teaching at Leiden University. ‘We’re going to set to work on complex sustainability challenges in our own backyard,’ says project leader Eefje Cuppen.

A stretchy sheet over a bowl representing space, a marble on it's surface creating a dimple, deforming space. Simple classroom experiments like these are featured in new educational videos by AstroEDU. In the videos Leiden astronomers Maria Cristina Fortuna and Henk Hoekstra explain what we know of…
