The Green algae Chara as model system for intra and inter cellular transport processes.

A couple of years ago, theoretical physicist Carlo Beenakker tracked down the Majorana particles and inspired Leo Kouwenhoven from TU Delft to try to create them in a superconducting nano-structure. He succeeded in doing so in 2012, and the news made headlines around the world. But a lot of work still…

These are the proposed research projects for LEAPS 2019. Please note that not all projects will go ahead and some may still be added in the near future. Final funding decisions lie with the Faculty sponsors. And please make a note that if you are interested in an ESA project, to check if your state…

The emergence of new players on the world market such as India, Brazil, China, Turkey and the Gulf States gives Africans more choice in who they work with and under which terms. At the same time, African multinationals are choosing to work with regional partners and are thus furnishing old political…

Many hot, rocky planets outside of our own solar system started out as large, gaseous Neptunes. This is what astronomers at Leiden University contend in a recent online publication.

A revolutionary supercomputer with energy-efficient parts that are available in the shops. Professor of Computational Astrophysics Simon Portegies Zwart has been awarded an NWO Medium Grant to build this processing giant, which will have the power of a supercomputer but requires only one percent of…

This Saturday will be the first Kaiser Spring Lecture of this year! - A series of public lectures on Astronomy in the Old Observatory.

Mathematical and computational analysis of the dynamics of polar transport of the plant hormone auxin.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

Researchers from Leiden University will develop a new approach to study the biomarkers of Alzeimer’s disease. This approach focusses on the molecular messengers of the cells. The project, led by Thomas Hankemeier and coordinated by Yuliya Shakalisava (Leiden Academic Centre for Drug Research, LACDR),…

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

Exponential population growth and rapid urbanisation are prompting the development of gigantic African metropolises that must be supplied with resources such as food, water and energy. This creates economic opportunities, drives migration and presents political challenges. Researchers from Leiden combine…

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…

The European Commission has started an investigation into possible illegal state aid from the Netherlands to Nike. It is high time that agreements between Tax Authorities and multinationals are made public, says Associate Professor in Tax Law Jan Vleggeert.

For the next six months the Van Vollenhoven Institute of Leiden University, together with The Asia Foundation (TAF), will develop a tool for evidence-based land policy in Timor-Leste.
