Due to technological and societal developments, we are being flooded with more information than our brains can process. How does this affect our decision-making, both as individuals and as a society? And can we learn to make better choices? This is what Lotte van Dillen will explore with her profess…

Having a bachelor's, a master's and a PhD in Chemistry, Elena Sánchez López shifted to a more biological field of research for her postdoc. She completed all her studies at the University of Alcala, in Spain, before applying for a LEaDing fellowship at Leiden University, a Marie Sklodowska-Curie Cofund…

Danen will work together with biologists and theoretical and experimental physicists from Dutch Universities. ‘Understanding these…

‘We didn’t find any mechanisms in the brain for transmitting child abuse from generation to generation. What we did find is that experiences of neglect and abuse affect the brain differently,’ concludes Lisa van den Berg (Clinical Psychology). PhD defence 30 June.

People who have negative expectations about a treatment actually experience more pain. Merve Karacaoglu discovered in her PhD research that anxious and pessimistic individuals are particularly susceptible to this nocebo effect. However, this sensitivity comes with a silver lining.

The effects on local government of the financial crisis that began in 2007 are still largely unknown. As a case study, Jan Porth conducted statistical analyses of the implications for Dutch municipal finances. The crisis became most apparent in the sale of municipal land to private companies and households.…

An international team of laboratory astrophysicists and astrochemical modellers has shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in space. The results have been published this week in Nature Astronomy and…

Claartje Levelt is professor of First Language Acquisition. She researches how babies and toddlers learn their mother tongue. Besides her work, she enjoys being involved with music.

AI can help scientists to collect data about the earth faster. This saves them a lot of time on trying to figure out how to analyze all the data they collect. Julia Wasala, PhD student at the Leiden Institute of Advanced Sciences(LIACS), tells us how AI can be used to save time.

The United Nations (UN) made history in October 2000 when Resolution 1325 on Women, Peace, and Security (WPS) was unanimously adopted.

The placebo effect was completely new to her when Lingling Weng began the PhD project in Leiden. She is now a postdoc in China. 'It would be great to investigate the underlying mechanisms of placebo and nocebo effects with my current knowledge of EEG and fMRI.' PhD defence on 17 October.

An international group of scientists has discovered that certain cells of our immune system – the so-called T cells – communicate with each other and work together as a team. To fight an infection they stimulate each other’s growth, but at the same time, they inhibit each other when there is a surplus…

The Repository from the Drug Disease Model Resources (DDMoRe) consortium provides a home to a collection of computational models of disease and drug action that have been used in pharmaceutical and/or academic research. This publically available open-access resource will make it easier for researchers…

A flu virus could cause a pandemic. And then we would be poorly armed because flu viruses are starting to become resistant to flu medications like Tamiflu. Chemist Merijn Vriends successfully worked on an improved version of such medications. He will be awarded his doctorate on September 12th.

The Veni grant is awarded annually by NWO (Netherlands Organisation for Scientific Research). This year, multiple researchers from Leiden University and 2 researchers who will soon be working at the university will receive a Veni grant from the NWO. Thanks to this grant, which can amount to up to 320,000…

Two bacterial species team up inside the plant root system to rescue their host from fungal infection. This was discovered by a team of microbiologists and bioinformaticians from the Netherlands Institute of Ecology, Wageningen University, and the Institute of Biology Leiden. They also identified the…

For the first time, it was shown in living cells how the bacterium E. coli regulates genes that help it survive in a new environment.

International courts and tribunals depend on state funding, creating a potential risk of undue state interference in judicial processes. In her doctoral thesis, Maria Manolecsu explores mechanisms that safeguard judicial independence, ensuring that courts can adjudicate without external pressure or…

The fact that scientists are increasingly better able to access molecular cell and tissue data also brings with it a new challenge: how can scientists find the information they need for research among the vast amount of data available?

Catalysts are indispensable in everyday life. We know what they do and more or less how they do it, but we still lack a fundamental understanding about their functioning at an atomic scale. Therefore, Irene Groot from the Leiden Institute of Chemistry develops new measuring techniques to unravel the…
