Het onderzoek van Anne Helder toont aan wat in het brein gebeurt als lezers een tekst lezen waarin iets staat dat niet klopt. Promotie 15 november.

Hoe kunnen mensen hun prestaties verbeteren en hun creatieve potentieel benutten? Dat is het onderwerp van het nieuwe Journal of Cognitive Enhancement. Dit interdisciplinaire wetenschappelijke tijdschrift is een initiatief van de Leidse psycholoog Lorenza Colzato. Eerste publicatie maart 2017.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

Triplet superconductivity refers to a condensate of equal-spin Cooper pairs (pairs of electrons with equal spin).

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

Endocannabinoids are lipid messengers that modulate various physiological functions by activating the cannabinoid CB1 and CB2 receptors. While the metabolism of endocannabinoids and their action at the CB receptors is fairly well studied, the molecular mechanisms governing their release and transport…

Galaxies in the Universe are distributed along the intricate framework of the Cosmic Web. Groups and clusters of galaxies comprise the densest regions in this network, and therefore, are excellent cosmic laboratories to study different aspects of galaxy evolution in extreme environments.

The Low Frequency Array enables studies of low-frequency carbon radio recombination lines with unprecedented sensitivity, spectral and spatial resolution.

An assessment approach that tailors to children’s instructional needs

Het ProMiSe project heeft als doel om de ontwikkeling van kinderen met het Coffin-Siris syndroom en FOXP1 syndroom te onderzoeken. Deze kennis is belangrijk om ouders en zorgprofessionals beter te kunnen informeren en hen te ondersteunen bij de opvoeding.

Het onderzoek van de sectie Cognitieve Psychologie is onder te verdelen in twee domeinen.

Lorenza Colzato wil onderzoeken of het gebruik van probiotica en tryptofaan de sociaal-cognitieve achteruitgang die optreedt bij het ouder worden, kan vertragen. Daarvoor ontvangt Colzato samen met haar collega's in Duitsland en Spanje een JPI 'A Healthy Diet for A Healthy Life' Joint Transnational…

Hoogleraar cognitieve psychologie Mariska Kret ontvangt de Dr. Hendrik Muller Prijs van de Koninklijke Nederlandse Akademie van Wetenschappen (KNAW) voor haar vernieuwende onderzoek naar emoties. Kret: ‘Deze prijs biedt een mooie kans om het emotie-onderzoek een boost te geven.’

Standaard schooltesten als de CITO-toets laten vooral zien wat kinderen al goed kunnen. Dynamische testen geven juist inzicht in hun potentieel om te leren, ontdekte Mirjam de Vreeze in haar promotieonderzoek. Vooral bij kinderen met leerproblemen als dyslexie of faalangst biedt dat perspectief.

De ziekte van Parkinson is een neurodegeneratieve aandoening die niet alleen wordt gekenmerkt door motorische symptomen, maar vaak ook gepaard gaat met cognitieve problemen. In deze pilotstudie zal worden onderzocht in hoeverre digitale thuistesten een haalbare en effectieve aanvulling kunnen zijn op…

To contribute to the body of knowledge aiming at a better coverage of ecosystem service assessment in LCA studies, this thesis dives into the challenges of incorporating existing ecosystem service methods within the impact assessment phase of the conventional LCA framework.

Mechanical metamaterials are carefully engineered materials whose properties are controlled by their structure, not by their composition, which allows using metamaterials to study and control physical effects in detail⁠.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

Promotores: C. J. ten Cate; M. A. Ainslie. Co-promotor: W. Slabbekoorn

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

In een virtuele wereld gaan Artis-chimpansees op zoek naar voedsel, waarbij ze zelf keuzes maken en hun nieuwsgierigheid laten zien. Onderzoeker en Artis-hoogleraar Karline Janmaat vergelijkt dit gedrag met dat van chimpansees in het wild. Hierover en meer vertelt Karline Janmaat in NRC.

Geldzorgen hebben impact op je brein. Wie denkt eigen schuld, dikke bult, heeft het mis. Gedrags- en neurowetenschapper Mirre Stallen legt in een video van Universiteiten van Nederland uit waarom schulden niet altijd je eigen schuld zijn.
