Een sterrenstelsel kan groeien door gas uit zijn directe omgeving naar binnen te trekken. Maar astronomen weten nog niet precies hoe dit gebeurt. Sterrenkundige Joop Schaye gaat met een Europese onderzoekssubsidie van 1,5 miljoen euro op zoek naar antwoorden.

Van onderwijs tot een verrijkende ervaring

Does knowledge of environmental performance change farmer's behaviour?

Wat doet de Universiteit Leiden om haar gebouwen en campussen toekomstbestendig en onafhankelijk van fossiele energie te maken?

Dankzij een slimme nieuwe techniek zijn Leidse astronomen er voor het eerst in geslaagd om de atmosfeer van een exoplaneet gedetailleerd te onderzoeken. De resultaten van hun onderzoek worden op 28 juni gepubliceerd in het tijdschrift Nature.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Do selenium nanoparticles in fish food cause subtle alterations in behavior of fish: effect of particles size and concentration?

A common method to solve expensive function evaluation problem is using Bayesian Global Optimization, instead of Evolutionary Algorithms.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.

Dissolving microneedles are a subgroup of microneedle types that completely dissolve within the skin. During this dissolving process the vaccine, stored in the needle matrix, is released into the skin.

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

The aim of the research presented in this thesis was to develop new methods forchallenging systems in liquid-state NMR using paramagnetic effects generated by thetwo-armed probe CLaNP-5.

Large carnivore population is globally declining as a result of the fragmentation of habitat, large prey depletion and retaliatory killing by pastoralists.
