Producing offspring of a crop without sowing and that is even bigger than the parent plant. According to Leiden researchers this can be achieved by overstimulating a single gene that rejuvenates cells, including bringing them back to the embryonic phase.

Reputation literature has provided crucial insights about the evolution of the US regulatory state. Daniel Carpenter’s influential account painstakingly demonstrates the relevance of reputation to bureaucratic ‘power’ and to early institutional state-building in the US context. We argue that adopting…

In this thesis, I studied the origin and evolution of the non-thermal radiation in merging galaxy clusters.

Asexual procreation in female wasps leads to an accumulation of genetic mutations, and the shrivelling of their sex organ. Leiden biologist Ken Kraaijeveld published this discovery in Evolution. His research is one of the first experimental studies into the consequences of asexual procreation.

If male budgerigars can successfully open a puzzle box with food, they become more attractive to females. Biologist Carel ten Cate and Chinese colleagues published experimental evidence for this in a paper in Science on 11 January. Various Dutch and international media wrote about the paper.

Leiden evolutionary biologist Maurijn van der Zee has co-operated on an enormous international project to describe the genetic material of the pea aphid Acyrthosiphon pisum. The more than 100 authors involved in the project have published their findings in the online magazine PLoS Biology.

Harvesting rice from the same field, without planting new rice plants? A discovery may bring this scenario closer. Leiden scientists have discovered a gene that allows annual plants to grow after flowering, instead of dying. Publication on 13 April in Nature Plants.

Cut marks on the bones of bears show that people in North-West Europe used bearskins to keep warm 300,000 years ago.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

In the past years access to EU law has been significantly enhanced via services such as EUR-Lex. This development not only allows for easy retrieval of individual legal acts, but for collecting information about the evolution of EU law in the aggregate as well.

Archaeologist Dr Gerrit Dusseldorp's research project was covered by a South African newspaper. Dusseldorp and his team investigate the evolution of human behaviour through artefacts dug up in South African caves.

Merijn de Bakker and colleagues of the IBL-research group of Prof. Mike Richardson provide a unique view on digit evolution in crocodiles and birds in their recent study published in Nature.

In an unpredictable environment bacteria evolve the same strategy as shareholders who try to protect themselves against unpredictable swings in the stock market. Experimental evolution biologist Dr Bertus Beaumont published an article on this discovery on 5 November in the journal Nature.

The SNP genotyping line offers flexible genotyping for small and large projects at affordable price and high quality. The use as SNPs as molecular markers is very versatile and can be used for a wide variety of scientific questions ranging from paternity analysis, conservatuion genetis towards QTL…

This interdisciplinary research project explores several adaptive machine learning methods which can give insight into the interaction between human and machine. The ultimate goal is open and natural communication between humans and AI that should result in mutual trust, cooperation and coordination…

Recent studies of Neandertal body mass and skin surface indicate raised energetic requirements in this lineage compared to anatomically modern humans.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

The Role and Effectiveness of the G20. In this article, published in The Changing Global Order part of the United Nations University Series on Regionalism book series, author Jaroslaw Kantorowicz discusses the evolution of the G20.

Within the two-year Astronomy master’s programme, you can choose from seven specialisations, ranging from fundamental or applied astronomy research in cosmology, instrumentation or data science, to combinations of astronomy research with education, management or science communication.

This project investigates the well-preserved agricultural terraces of the Inn valley and the evolution of resource use in the inner Alps.

The central theme of Rik Mom’s research group is to identify what the electrode-electrolyte interface looks like when electrocatalysis is taking place. Using specialized forms of Raman and X-ray spectroscopy, we study the chemical state and bonding environment of the electrode surface and near-surface…

As the flagship journal of the National Academy of Sciences USA, PNAS publishes several special features each year highlighting topics that are expected to engage the interest of the journal’s broad readership. Archaeologist Wil Roebroeks was invited by the Editors of PNAS to contribute a paper on the…

LUCIS Visiting Fellow Lecture

From black holes to artificial intelligence and from drug research to data science: welcome to the fascinating world of the Faculty of Science. Our researchers, students and guests regularly give public lectures about their work. You are welcome to attend.

Political scientist Matthew Longo (Leiden University) takes a detailed look at the evolution of border security in the United States after 9/11. Far from the walls and fences that dominate the news, he reveals borders to be thick, multi-faceted and binational institutions that have evolved greatly in…

The Department of History and Art History externe link at Utrecht University is looking for a candidate for the PhD-project “The (R)evolution of Reconstruction: an analysis of digital facsimiles”. This project analyses the value of digital facsimiles for researchers, heritage institutions, and museum…

Two years ago, Amanda Henry joined the Faculty of Archaeology’s Archaeological Sciences department. She investigates diet and human evolution, with a specific focus on plant foods. ‘Most of the studies on the prehistoric diet focus on meat and hunting. This just didn’t make sense to me.’
