Two PhD defences on 9 June by behavioural biologist Errol Neo and underwater acousticianan Özkan Sertlek relate to measuring noise in the North Sea and the harm this noise can do to aquatic animals and their surroundings. Little is known about how harmful human noise can be to aquatic animals.

‘What I find most alluring about soil life is that you can steer it,’ researcher Martijn Bezemer of the Institute Biology Leiden (IBL) reveals. ‘You can ask: What do you want? And then I can transform the soil into something you need. At least, that is what we thought.’

With the search for new antibiotics becoming increasingly urgent, artificial intelligence offers valuable help. Smart software developed by Leiden PhD candidate Alexander Kloosterman searched genomes of bacteria and found clusters of DNA that code for proteins that have an antibiotic effect. ‘This new…

Few researchers see potential in research on glioblastoma, an incurable brain tumour. Alexander Kros brought together colleagues who are up to the challenge. European research funder ERC recently made 10.6 million euros available, a year earlier NWO provided 3 million euros. ‘In six years, we certainly…

Read all about YAL membership and the members of the Young Academy Leiden.

The school curriculum is often geared towards teaching the next generation of scientists, but in many ways, children already are natural scientists. Their curiosity pushes them to constantly question the world, and their creativity drives them to novel conclusions. However, too many children believe…

Anne Veens is on a mission. She wants secondary school students to get acquainted with anthropology, and think about the value it can have in the development and implementation of policy. To achieve this, she has developed a teaching package. Last July, she successfully ran the first pilot. 'Most pupils…
