A consortium of international researchers comes with a unique solution to the energy problem. By mimicking photosynthesis, they aim to produce sustainable fuels out of sunlight, water, and CO2. Their secret? ‘Soap bubbles’, says Leiden chemist Sylvestre Bonnet, who is part of the consortium.

A team of laboratory astrophysicists from Leiden University managed to make glycerol under conditions comparable to those in dark interstellar clouds. They allowed carbon monoxide ice to react with hydrogen atoms at minus 250 degrees Celsius. The researchers publish their findings in the Astrophysical…

The enormous adaptability of the cholera bacterium explains why it is able to claim so many victims. Professor Ariane Briegel from the Leiden Institute of Biology has now discovered that this adaptability is due to rapid sensory changes in the bacterium. Publication in PNAS.

Regular users of cannabis are less aware of their own mistakes, and they are not good at creative thinking. This is the conclusion drawn by psychologist Mikael Kowal from his research on the effects of cannabis. PhD defence 6 October.

The brains of adolescents react more responsively to receiving rewards. This can lead to risky behaviour, but, according to Leiden University research, it also has a positive function: it makes learning easier. Publication in Nature Communications.

In high school, Tim van Erven read about an artificially intelligent algorithm that could solve mazes. From that moment on, he was sold: ‘There’s something magical about algorithms. With a list of fixed rules you can make them learn the most diverse things.’ This year, he won a Vidi grant, which he…

Mimicking photosynthesis to produce bioplastics sustainably and efficiently. Researchers from the Institute of Biology Leiden (IBL) and the Leiden Institute of Chemistry (LIC) will assess this new approach. ‘An exciting opportunity to explore a new, appealing research topic in a collaboration between…

Previous research has shown that extreme shyness is hereditary, but because shyness is such a broad concept it is difficult to identify specific genes. Anita Harrewijn has discovered particular brain measurements that can help. PhD defence 18 January.

Data and information should be stored in a way that computers can understand, says Barend Mons, professor of Biosemantics at the Leiden University Medical Center and Chair of the High Level Expert Group for the European Open Science Cloud. We speak with him about FAIR data, knowlets and nanopublicat…

Despite the promising effects of technology in assessment and treatment, the actual use of novel technologies in juvenile justice context remains limited. We want to inspire researchers to develop and investigate technological applications for assessment and treatment for justice involved youth.

Neanderthals were able to make fire on a large scale with the aid of pyrite and hand-axes. This means they could decide when and where they wanted fire and were not dependent on natural fire, as was thought earlier. Archaeologist Andrew Sorensen has discovered the first material evidence for this. Publication…
