PNAS publication on protein encounter complexes

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

How do we experience electronic music? How does electronic music operate on perceptual, cognitive and affective levels? What are the common concepts activated in the listener’s mind when listening to electronic music? Why and how are these concepts activated?

From The Cognitive Continuum of Electronic Music: "The use of the electronic medium to compose music entails a variety of cognitive idiosyncrasies experienced by both the artist and the audience."

The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

The aim of this facility is to accelerate biomedical research by providing access to advanced light and electron microscopy and by sharing expertise about sample preparation, imaging modalities, data storage and image analysis.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

The principal aim of this research is to explore the confrontation between voice and electronics. These are often seen as being radically different from one another and many characteristics seem to be in opposition between them. However, they also have characteristics in common and they can influence…

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

The dissertation describes TEM experiments on heterogeneous catalysts.

My research focusses on site-specific compositional and performance practices of music for organ and electronics and their musical-spatial values.

Over the past decades the role of writing in the development of human civilizations has been the subject of much discussion. The adoption and development of literate skills has been linked to many developments in human history, be they cultural, social or even cognitive.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

What is the effect of practicing with electronic books on reading skills for grade 1 students?

Physicist Daniël Geelen has developed a new microscope that uses low-energy electrons. Those are less harmful to biological and organic materials. Geelen defends his PhD thesis on May 31st.

The main aim of this project is to investigate the various ways in which language categorizes possession, how these are morphosyntactically encoded across and within languages, and how this distinction should be represented in a model of the language faculty.

For the first time, physicists have visualized the ‘melting’ of electrons inside a special class of insulators. It allows electrons to move freely and turns the insulator into a metal and possibly later into a superconductor. Publication in Nature Physics.

Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.

The use of a new type of detector has generated a strong improvement in the resolution of electron microscopes. The 'low-energy electron microscope' (LEEM) can now be used for research on the thinnest possible materials. The tests with the detector represent the first result of the ESCHER project.

The Netherlands Organisation for Scientific Research (NWO) has made a subsidy of 17 million euros available to further develop a Netherlands network for electron microscopy (NEMI). The network comprises five UMCs and eight universities, with Utrecht in the coordinating role. From Leiden, the Institute…

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

Science Magazine has published three back-to-back papers on an important discovery in solid state physics. Leiden physicist Jan Zaanen wrote a Perspective article on the subject in the same issue of 4 March.
