Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Lysosomal glycosidases are acid hydrolases that fragment glycoconjugates in lysosomes.

This research note argues that the “lone wolf” typology should be fundamentally reconsidered.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

Sewer pipes are an essential infrastructure in modern society and their proper operation is important for public health. To keep sewer pipes operational as much as possible, periodical inspections for defects are performed.

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

Cognitive psychology is the study of cognitive functions such as attention, memory, consciousness, emotion, language and action control. The goal is to understand the complex relationships between brain, mind and behavior.

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

With the dramatic growth of the image data on the web, there is an increasing demand of the algorithms capable of understanding the visual information automatically.

Cyber security is one of the critical challenges in our inter-connected world. Organizations are being constantly targeted by adversaries. Various critical systems become exposed on the Internet. Users can find that their data has been stolen from a company that they were not even aware of.

The overall objective of this project is to identify novel drug candidates that are capable of slowing down the progression of neurodegeneration in the subset of Parkinson’s disease (PD) patients with overt mitochondrial dysfunction. Multimodal phenotypic characterisation of cohorts of monogenic PD…

The University’s Vision on Student Well-Being outlines how the University plans to promote student well-being in the coming years.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

More than 5,000 exoplanets have been found over the past couple of decades. These exoplanets show a tremendous diversity, ranging from scorching hot Jupiters, common super-Earths, to widely separated super-Jupiters on the planet/brown dwarf boundary.

In a new study, we found that when we are exposed to potential harm to the other person, it improves our automatic attentional processes to avoid harm to that person.

PhD candidate Wouter Verschoof-van der Vaart has received the Stichting Elise Mathilde Fonds grant from the Leids Universiteits Fonds (LUF) to work on a research project focusing on the landscapes of the Second World War. ‘We will combine citizen science with deep learning to uncover traces of the c…

To develop a new generation of brain science (and train scientists) focused on explaining complex real-world behavioural patterns.

A 35-year-old uranium crystal will not disclose its secret: what causes a dramatic phase transition at 17.5 Kelvin? Thanks to a new artificial intelligence approach, half of the possible explanations are excluded, but the definitive answer remains to be found. 'It is very frustrating', says physicist…

In the future, physicians may be able to identify dementia much earlier than they can today because a computer algorithm will be able to predict from brain scans how our memory is going to develop.

What is the role of auxin in the initiation and process of somatic embryogenesis?

What is the population size/structure and distribution of tiger and leopard inside the Bardia National Park (BNP) compared with the population outside? What is the movement and home range and conflict pattern in time and space of tigers and leopards inside the BNP compared with outside? What constitutes…

Joost Batenburg is a mathematician and computer scientist who works to build bridges to other disciplines. He hopes to bring intelligent software to fields where it can make a difference. Conversely, he also seeks connections to the disciplines that are needed to make AI a success.

Leiden University researchers and their collaborators report the development of new research frameworks that use day-to-day smartphone behavior gathered from a large sample of healthy people to help understand aging, and how aging alters with epilepsy and stroke. These reports occupy two back-to-back…

Grammatical gender is famously the most puzzling of the grammatical categories. We have a solid typology of gender systems, yet exciting and unexpected patterns keep turning up which defy easy classification and straightforward analysis. Some of these question, stretch or threaten to cross the outer…

The main research objective is to map the cities of Roman Asia Minor in terms of location, size, urban amenities and juridical status, with the specific aim to understand the reasons how this urban settlement pattern arose.

Radiation can be used to determine the isotope ratio of a skeleton. This provides information about where our ancestors lived and what they consumed. Dr Andrea Waters has developed a revolutionary method that can trace patterns of consumption from tens of thousands of years ago.

How is the development of physiological responses to social evaluation in adolescence affected by other normative developments, such as pubertal, socio-cognitive and psychosocial development? Are social anxiety and public speaking anxiety associated with characteristic patterns of stress responses…
