The BLRN members have published extensively in recent years. In addition to the BLRN book series, dissertations of BLRN members published in the E.M. Meijers Institute Series, you will find below a selection of our publications. For a more complete overview of publications of each BLRN member, please…

Joost Beltman (LACDR, Leiden University) has provided novel insights in the way T cells migrate towards virus-infected cells. This was accomplished by a combination of experimental research in the group of Ton Schumacher (Dutch Cancer Institute, NKI) and computer simulations in collaboration with Rob…

Philosophical pragmatism has found more and more applications. But thus far it has not been applied to political crisis management. Political scientist Martin Bartenberger linked these two together and discovered that pragmatism, or the lack thereof, can help to explain how governments and public agencies…

Professor Carlo Beenakker has been awarded a FOM Projectruimte subsidy to build a theoretical model of a majorana gun, a very promising instrument for quantum computers.

Five promising researchers at Leiden's Faculty of Science have received a Veni award from NWO. They can use the award - of up to 250,000 euros - to carry out research over a three-year period. Of the total of seventeen Leiden Venis, four went to Leiden Observatory and one to Institute for Biology Le…

The many thousands of small celestial bodies beyond Neptune’s orbit may have ended up there due to a star that passed close to the solar system billions of years ago. This is shown by Leiden simulation expert Simon Portegies Zwart, along with his German and Dutch colleagues. ‘We are answering several…

A night sky of more than 40 petabytes in size, simulating young star clusters and understanding how the body inhibits viruses: three Leiden projects have received computing time on one of the national computer systems.

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…
