A full overview of all loans and debts between banks would help preventing a new financial collapse. But banks do not provide this information. An econophysics model by Diego Garlaschelli and collaborators reconstructs the most probable situation and finishes first place in two independent tests.

Book on Dutch mayors governing local order and public safety.

How can we reduce CO2 emissions from industry? Leiden psychologists Emma Mors and Christine Boomsma are examining the public perception and acceptance around the capture and storage of carbon dioxide. This is part of the ALIGN CCUS European research programme.

De laatste puntjes en komma’s worden gezet op het hoofdlijnenakkoord van de beoogde coalitie. De betrokken partijen presenteren morgen hun plannen, waarna volgende week een afrondend debat volgt met de informateur. Staatsrechtgeleerde, Wim Voermans duidt de zaak in een uitzending van Sven op1.

What if we start taxing carbon-intensive products such as electricity and gasoline, and at the same time compensate low-income households? Hauke Ward and colleagues did just that in a computer simulation for Peru, with a remarkable outcome. Not only does the approach tackle climate change, but it could…

In this paper, Kantorowicz argues that reverse party favoritism exists. He exploits the fact that during the SARS-CoV-2 pandemic crisis, the Polish government was keen to launch postal voting in the presidential elections scheduled for May 2020.

Researchers from the Plant Ecology and Phytochemistry group at the Institute of Biology Leiden (IBL) received an STW (Stichting Technologische Wetenschappen) grant for applied studies in plant herbivore resistance with potential for a novel resistance test.

During his PhD research, mathematician Tyron Lardy worked on a new approach to hypothesis testing. Instead of the traditional p-value, he uses so-called e-values. These turn out to be more flexible – especially when you want to look at your results midway through the study.

Knowing whether or not a treatment is working just by wearing your watch? Data scientist Ahnjili ZhuParris has identified a lot of opportunities for the use of machine learning in clinical research to monitor test subjects at home.

Does gravity work the same when you look at the largest scales in our universe? That’s what Leiden physicist Alessandra Silvestri will study with a 2 million euro ERC Consolidator grant. ‘We assume that it does, but we don’t actually know.’

The two instruments of ESA's space telescope Euclid have taken their first test images. The first images indicate that the space telescope will achieve the scientific goals for which it was designed - and possibly much more. Euclid will create a 3D map of a third of the sky, allowing scientists to study…

Children could do better at school if they exercise during their maths, English and science lessons, a study has suggested. Researchers reviewed 42 studies that looked at the benefits of physical activity in the classroom for youngsters.

How to innovate education? In this series, the Honours Academy highlights examples from their educational testing ground that aim to inspire. Today: pioneering with podcasts. What are the do's and don'ts? Two teachers and a student share their thoughts.

Jianfeng Ge and Milan Allen of Leiden University look for majorana quasiparticles using shot noise measurements

Leiden PhD candidate Jo-Anne Verschoor discovered that nearly twenty percent of the bacterial strains she studied could degrade plastic, though they needed some encouragement to do so. ‘Bacteria are just like people,’ says Verschoor. Her research was published in the journal Communications Biology,…

PhD candidate Sibel Bahtiri is one of the new Faces of Science. In videos and blogs, she will show what life is like as a young researcher.

This dissertation is about Bayesian learning from data. How can humans and computers learn from data?

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

In this PhD-thesis several new and existing data science application are described that are particularly focused on applications for tax administrations.
