Several single-stranded RNA viruses make use of Xrn1-resistant RNAs in their 3’ untranslated regions of their genome RNAs in order to increase their pathogenicity.

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

In de zomer van 2023 trokken geïnteresseerden eropuit om de luchtkwaliteit in Leiden in kaart te brengen. Met behulp van een techniek van Brits kunstenaar Robin Price maakten ze het onzichtbare zichtbaar om zo het gesprek over het belang van goede luchtkwaliteit te kunnen starten.

Where and how are critical materials currently used and how can this information be used to develop scenarios about their future demand.

The Institute of Environmental Sciences has carried out and participates in several projects that deal with the analysis of energy systems.

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

Animal diet studies are critical for understanding ecological processes such as trophic interactions, energy flow, and nutrient cycling. By examining what animals consume, ecologists gain insights into species specialization, predator-prey relationships, and ecosystem management.

Although nanoparticles are extensively used in various applications like consumer products and have most probably entered the environment, little is known about the effects of these particles on living organisms.

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

My work focuses on a class of astronomical objects called protoplanetary disks.

Like a mixture of oil and water, lipid membranes separate into two liquid phases.

In order to gain a better insight into the basis of the rapid jasmonic acid (JA)-mediated stress response, an integrated approach using a targeted high-resolution mass spectrometry-based (HRMS) platform, was conducted to monitor the metabolism of JA using the model system of cell suspension cultures…

This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

Plant-microbe interaction resulted in different physio/chemical responses by host plant and interacting rhizobacteria.

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

In de Faculteit der Sociale Wetenschappen is de verwevenheid van onderzoek, onderwijs en impact vanzelfsprekend.

Microbiome composition of the spermosphere and the rhizosphere of wild and modern bean accessions grown in an agricultural and a native soil from Colombia was characterized by metagenomics and cultivation-dependent approaches.

The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…
