The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

The relevance of intentionality to the interpretation of Aristotle was first suggested by Brentano in his Psychology from an Empirical Standpoint. Here we take our starting point from Brentano and investigate how Brentano’s concept of intentionality is rooted in Aristotle.

How did toxin genes evolve from harmless physiological genes?

Can we tailor catalysts at the atomic scale by means of high-school chemistry and geometry rules?

Evolution & Biodiversity is one of the four research themes of the Institute of Biology Leiden.

The central subject of this dissertation is the influence of Fichte’s theory of self-consciousness on Søren Kierkegaard's philosophical notion of the self in the way Kierkegaard describes the self in his philosophy in the writing 'The Sickness unto Death' (1849). The main question this dissertation…

The HARVEST project explores the dietary choices that our hominin ancestors and relatives made, by recovering information on what they consumed, and how factors like environmental variation, intrinsic biology, and development of food processing technologies could have influenced their decisions.

Female and male songbirds sing equally elaborate songs in some species, but in others, females do not sing like males or not at all. How did such pronounced differences in male and female communication evolve?

The Great Rift Valley in Africa is a real treasure trove for discovering early human fossils. The fossils found in this part of Africa have determined our view of human evolution. But was the Great Rift Valley really the place where evolution took place or just a place where fossils are well preserved…

Studies in Human Evolution is a series of the Faculty of Archaeology, Leiden University and The Max Planck Institute for Evolutionary Anthropology, Leipzig.

Why do plants produces always produced so many slightly differing metabolites within a particular chemical class?

Microbial Sciences' contribution to the Evolution & Biodiversity research theme focuses on understanding how bacteria sense and respond to their environment, and how bacterial diversity and evolution is influenced by cooperative and antagonistic interactions taking place between microbes.

Animal Sciences’ contributions to the Evolution & Biodiversity research theme include evo-devo research, the evolution of cognitive and behavioural traits, and the evolutionary mechanisms of stress adaptation. This research involves both indoor and outdoor studies.

Plant Sciences' contribution to the Evolution & Biodiversity research theme is to understand what are the key drivers of plant biodiversity during evolution with a focus on plant life history and resilience traits and develop tools to restore and maintain plant biodiversity.

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

Negotiation can only really be an alternative to warfare, if the parties agree on a framework of rules and procedures. And if the confidence of the partners may increase in another. But negotiations continue to wage war by peaceful means.

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

In order to compare languages, it is important to have a thorough knowledge of the specific languages you are studying. Gijsbert Rutten and his team are investigating the origin of Standard Dutch and the repression of ‘non-standard’ variants between 1750 and 1850.

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Sustainable energy from wind and solar is most readily available near the sea.

What the Sex Lives of Bugs, Birds, and Beasts Tell Us About Evolution, Biodiversity, and Ourselves, Menno Schilthuizen reports from the front lines of evolutionary biology, on a quest to make sense of the origins, workings and evolution of our and other species’ reproductive selves.

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

A study by a Leiden-Wageningen group shows that present-day humans are biologically poorly equipped to deal with the toxins they are regularly exposed to in smoky environments: compared to earlier hominins, we modern humans are probably even worse off. The study appeared in Molecular Biology and Evolution.…
