Giant galactic outflows and shocks in the Cosmic Web
The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Nucleosome stacking in chromatin fibers probed with single-molecule force- and torque-spectroscopy
In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

Terug naar de scanner: hersenwetenschap in coronatijd
Veel neuropsychologen maken voor hun onderzoek gebruik van de hersenscanners in het LUMC. Toen de coronacrisis uitbrak werden de toegangseisen voor het ziekenhuis flink aangescherpt, en dreigde heel wat psychologisch onderzoek in de soep te lopen. Dankzij goede protocollen kunnen de onderzoekers nu…

The Role of Linker DNA in Chromatin Fibers
The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

Werking versterkstoffen MRI in kaart gebracht
Speciale versterkstoffen kunnen MRI-scanners honderden malen gevoeliger maken. Leidse fysici hebben nu een methode gevonden om hun efficiëntie te toetsen. Gevoeligere MRI-scans kunnen bijvoorbeeld taaislijmziekte of Parkinson begrijpelijker maken. Publicatie op 18 januari in PCCP.

Knots in plasma
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.

Plasmonic enhancement of single-molecule fluorescence under one- and two-photon excitation
This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…
