A full overview of BPOC/SSNMR PhD theses.

The Horizon 2020 project Sybil-AA (Systems Biology of Alcohol Addiction) focuses on modeling and validating disease state networks in human and animal brains for understanding pathophysiology, predicting outcomes and improving therapy in alcohol addiction. Alcohol addiction, the most severe form of…

The aim of ANCIENT CHARM was to develop neutron-imaging techniques and the associated equipment, and help establish neutron imaging as a mainstream archaeological analytical technique. In particular, one of the goals was a new imaging technique which called neutron resonant capture imaging combined…

Research groups in the Quantum Matter & Optics programme investigate electronic properties of matter and light-matter interactions with emphasis on quantum information.

Together with researchers from over the world, the ENIGMA-Anxiety Working Group endeavors to unravel the neurobiology of anxiety disorders and related constructs.

This month the University and several partners signed the rental contract for the brand-new Spui building. What will this location mean for the future of Campus The Hague, Leiden University and the population of The Hague? Martijn Ridderbos explains in his column.

Can a proposed new radiofrequency approach to graphene biosensors lead to groundbreaking changes in genome mapping?

How do practice and theory reinforce one another in neuroscience? Professor Birte Forstmann’s inaugural lecture on 2 October will be about building interdisciplinary bridges between cognitive neuroscience and cognitive models. Her approach may lead to brain research with fewer side-effects for patie…

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

With his ice-cold nano force sensor, Tjerk Oosterkamp searches for the boundary between the quantum world and the everyday world. The Leiden physicist has received an NWO subsidy of 600,000 euros.

On the 15th of July Sawako Takemura successfully defended a doctoral thesis and graduated.

How do you fit two meters of DNA in a tiny compartment and at the same time are able to access the right parts of it at the right times?

PURPOSE: To determine the effect of elasticity on the skin permeation of ketoprofen from surfactant-based vesicular formulations and elastic liposomes.

Nuclear Magnetic Resonance (NMR) Spectroscopy is a non-destructive analytical technique that is used to study the nature and characteristics of molecules with an atomic level precision. It has a wide range of applications especially in synthetic chemistry, biological and biochemical research groups…

Can metabolomic profiling be used to predict resistance against insect herbivores in plants?

The death of George Floyd at the hands of the police may have sparked the Black Lives Matter protests in the United States and here in the Netherlands, but they are about more than that alone. We asked Karwan Fatah-Black, a historian who specialises in the Dutch colonial history, for his analysis. ‘We…

Vocal learning is a trait shared by songbirds and humans. It is also a trait that is restricted by the brain rather than by a species' vocal apparatus. In this dissertation, functional MRI is employed in both species in order to explore potential common neural mechanisms underlying the ability to develop…

Mathilde Mechling defended her thesis on 28 january 2020.

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-…

Mazène Hochane and Xueying Fan have won the fourth annual LION Image Award. They created a detailed colour image of a human kidney in development.

This dissertation examines what network in the human brain is involved in the perception of prosody and whether activity within this network is modulated by the personality trait alexithymia.

Promotor: Prof.dr. T. Schmidt, Co-promotor: Dr. ir. S. J.T. van Noort

This project investigates the transposition of natural historical material, knowledge and vision, between different media (collection, scientific drawing, academic texts, the visual arts and/or literature) – a transmission that happens in the borderline between the traditional, emblematic worldview…

Molecules are extremely hard to see in visible light, especially without using fluorescence. Leiden physicists have now made their optical technique sensitive enough to image the molecules of their interest in all sizes. Publication in Nanoletters.

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.

The Joan van der Waals colloquium is an ongoing bi-weekly lecture series.

Four years of protracted negotiations and bitter warfare passed between the declaration of Indonesian independence on 17 August, 1945, and the official transfer of sovereignty on 27 December, 1949.

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.

How do you microscopically image zebrafish larvae? The new free online course ‘Imaging the Vertebrate embryo’ teaches you all about it. Leiden PhD candidates Salomé Muñoz Sánchez and Radoslaw Gora contributed to the course.

2020 was an eventful year. You can see that in our photos: one and a half metres distance, an empty university, attending ceremonies online and working from home. The image editors have selected the twelve most eye-catching photos of the past year..

The winning picture by Sander Blok in the annual Physics Image Award has made it to Leidsch Dagblad. The runner-up image by Jelmer Wagenaar has been selected as Beeld van de Week in De Volkskrant.

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…

Research groups in the Biological & Soft Matter Programme unravel mechanisms in biological processes and develop novel bio-inspired soft materials.

To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…
