Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.

Leiden physicists have managed to detect a single molecule called dibenzoterrylene in a new crystal, and found that it is a candidate component for a quantum network. Future quantum computers will need such a network to work together while maintaining their advantages. Publication in ChemPhysChem jo…

In this thesis, the focus lies on studying glucocorticoid receptor dynamics in living cells with the aim of understanding how this transcription factor finds its DNA target sites to regulate transcription.

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

A group of single-celled organisms organises its DNA in a similar way to higher organisms such as plants, animals, and fungi. However, the way packaged DNA is read out differs between the two related groups, Bram Henneman discovered. PhD defence on 5 December.

Individual molecules are extremely hard to see through feeble fluorescence. Tiny gold nanorods serve as new antennas to intensify their signal 500 times. Publication on 24 February in Angewandte Chemie.

Single-celled organisms have stiffer DNA than multicellular lifeforms like humans and rice. Theoretical physicists managed to simulate the folding in full genomes for the first time to reach this conclusion. Publication in Biophysical Journal on February 7.

Ferritin is a spherical metalloprotein, capable of storing and releasing iron in a controllable way. It is composed of a protein shell of about 12 nm and within its cavity, iron is stored in a mineral form.

The last blog of Leiden Law Blog of 2018 was written by Ladislav Kováč. He discusses the proposal for the Single-use Plastics Directive of the EU which was agreed upon on 19 December.

On Friday 17th September 2021 an inaugural lecture was held by prof.dr.ing. Bram Klievink entitled: 'Hollen én stilstaan: hoe data en digitalisering de overheid veranderen'.

Sense Jan van der Molen is vanaf 1 maart de nieuwe wetenschappelijk directeur van het Leiden Instituut voor Onderzoek in de Natuurkunde.

The findings in this thesis improve the understanding of 1) the relationship between exposure characteristics and toxicity of ENPs, 2) the joint toxic action of ENP mixtures and the comparison to metal salt mixtures, 3) how NOM affects the individual and joint toxicity of ENPs, 4) the extent of trophic…

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

Caspar van den Berg was asked by Dutch news programme EditieNL for a reaction to the new coalition agreement and the ministerial team. Some ministries are set to have two ministers. Can that go well? View the excerpt.

Paleobotanist Menno Booi discovered that 250 previously described fossil tree species are objectively not distinguishable; they belong to only one single species.

Healthy aging is one of the prime goals in today's society and atherosclerosis is among the greatest causes of morbidity in elderly. Cardiovascular disease patients receiving treatment are often of advanced aged and have an aged immune system, which limits translating experimental findings to the pa…

Fate and toxicity of copper nanoparticles was related to the water chemistry of the environment and pristine size.

Emily den Boer of LAPP visited the Canal Cups Expo, displaying the plastic cups cleaned up by students after Leidens Ontzet.

The adsorption of D2 and CO2 on catalyst surfaces is studied using a molecular beam in ultra-high vacuum.

Astronomers who simulate galaxies do not always get the same result, even when they start from identical conditions. New research from Leiden University shows that this is not a flaw, but a consequence of how galaxies behave — and how they are modelled.

In this paper, Sarah Giest and Bram Klievink highlight the effects of AI implementation on public sector innovation. This is explored by asking how AI-driven technologies in public decision-making in different organizational contexts impacts innovation in the role definition of bureaucrats.

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.
