Cognitive enhancement is het gebruik van elke methode of techniek met als doel het verbeteren van cognitieve prestaties.

This multidisciplinary minor provides students with knowledge on how and why humans became the way they are. The minor focuses on the evolution of the species Homo sapiens from other hominin lineages and animal ancestors, and on the various factors shaping this process. Not only is human evolution of…

In this course, you will develop an understanding of evolutionary processes and their formative power. You will see how evolution has shaped biodiversity, and continuously influences our daily life.

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

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

Op 1 april 2020 verdedigde Marc Broekema zijn proefschrift 'Cognitive Bias in the Judgment of Business Valuations and Valuators'. Het promotieonderzoek is begeleid door promotor prof. dr. J.I. van der Rest.

In my research, I used a comparative wood anatomical approach to address wood evolution of the (largely) tropical flowering plant families Apocynaceae and Sapotaceae.

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.

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

Veel kinderen leren niet op een niveau dat aansluit bij hun potentieel om te leren. Diagnostiek in de leerlingbeleiding zou daarom inzicht moeten geven in hoe een kind begeleid kan worden in het verder ontwikkelen van zijn of haar sterke kanten terwijl het tegelijkertijd handvatten biedt voor het ondersteunen…

Electrocatalysis allows for storing electricity or converting it into chemical bonds, producing chemical building blocks and fuels using renewable resources.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

One of the most important puzzles in modern astrophysics is the nature of dark matter.

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.

The role of the interfacial environment during electrochemical reactions has been increasingly valued, especially for those reactions involving protons or hydroxyl ions.

Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.

The investigation into the bidirectional communication between the gut and its host is a rapidly growing area of research, attracting considerable attention for its potential to provide crucial insights into health and disease.

Planets are formed in disks of gas and dust around young stars.

Op 12 october promoveert Fatemeh Tabassi Mofrad. Het Leiden University Centre for Linguistics feliciteert Fatemeh!

This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

In this study, we investigated the electrochemical behavior and surface evolution of Au(111) electrode under different conditions and electrochemical techniques, using a homemade electrochemical scanning tunneling microscope (EC-STM), revealing the intricate interplay between surface roughening, atom…

Bernard Bernards onderzoekt beperkingen op innovatie door te focussen op cognitieve onzekerheid als toestand die innovatief werkgedrag kan beïnvloeden.

On 4 and 5 November 2021 an ICOG-workshop will be held on the cognitive turn in history. It is possible to attend this workshop online. The participants of the workshop are cultural and intellectual historians of the pre-modern periods and/or of the historiography of academia from a long-term perspective,…

The logic seems inescapable indeed. The bigger the population, the higher the probability it contains an Einstein. Hence, bigger populations are more likely to develop complex culture.

The explosive radiation and diversification of the advanced snakes (superfamily Colubroidea) was associated with changes in all aspects of the shared venom system. Morphological changes included the partitioning of the mixed ancestral glands into two discrete glands devoted for production of venom ormucous…
