LENS is engaged in the drawing up a cartography of the mediascape, past and present, researching the dispositifs and ecologies of image production and presentation, which stretch across diverse geo-political areas as well as institutional, discursive and technological fields.

Abbas provides an in-depth analysis of the complex interplay between Zionism, Jewish identity, power dynamics, and the Israeli-Palestinian conflict.

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

This article investigates how temporary coalitions of non-state actors engage in international negotiations on environmental issues.

On the 28th of June, Laura Smorenburg successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Laura on this achievement!

Systems pharmacology aims to apply techniques from systems biology to pharmacological models.

Reactions and reaction times in cognitive tasks.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

Patterned detectors are an existing technology that can be found in almost all color cameras.

In this opinion article published in World Development, the authors present five research and policy priorities. While it is clear that ‘pluriversal’ designs need to guide the way forward (Kothari et al 2019), defining a set of key pillars can provide direction and purpose across this pluriversality.…

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

This study seeks to partially fill the knowledge gap about national culture in Africa, basing its research on data on ethnolinguistic groups (instead of administrative regions).

Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

This dissertation explores how Large Language Models (LLMs) can effectively and responsibly contribute to complex decision-making processes. By combining AI and human intelligence, Hybrid Intelligence (HI) emerges, allowing the strengths of both humans and machines to be utilized.

This book presents an understanding of the concept of Countering Violent Extremism from a critical terrorism studies perspective using case studies from different countries while examining the issues it raises.

From 1550 onwards, a great interest in the natural world developed across Europe. This interest was not only stimulated by a growing knowledge of local flora and fauna, but also by the import of numerous exotic animal and plant species. Think, for instance, of researches and collectors like Gessner…
