During their holidays, students bio pharmaceutical sciences and computer science visited special summer schools in China. ‘China is a global player that we should…

A staggering 6.5 billion chicks are killed worldwide every year. These are generally male chicks that are of no economic value. In Ovo has developed technology that can quickly determine the sex of a chick, to ensure that only female chicks are hatched. The first 150,000 chicks have now hatched in this…

A vaccine based on sugar coats does have the potential to combat a multi-resistant staphylococcus. That is what Jeroen Codée and his colleagues from Utrecht state in Nature. In doing so, they are contradicting the earlier conclusions of German colleagues.

The CML of Leiden University, together with the Netherlands Environmental Assessment Agency (PBL), TNO, Utrecht University and RIVM, is investigating what is needed to achieve…

For medical research, researchers often recreate tissue in the lab. Organ-on-a-chip technology emulates organs, right down to the blood that flows through them, thus creating a realistic test model for drugs or research into disease processes. Researchers from the LUMC are coordinating an NWO Gravitation…

Leiden University is 444 years old this year! And we have big plans to celebrate this special birthday in 2019 - together with the people of Leiden and The Hague.

Those pesky raindrops that get you wet on your way to work, are formed high up in the sky from clouds of water vapour. The process of nucleation describes the way this happens. Edgar Blokhuis of the Leiden Institute of Chemistry developed a theory to describe this transition more precisely. Chemists…

To facilitate the search for new antibiotics. That is the aim of Gilles van Wezel, professor molecular biotechnology at the Institute of Biology Leiden (IBL). He wants to do this by looking at similarities in the DNA of antibiotic-producing bacteria. Van Wezel has been awarded an ERC Advanced grant…

The Phase 3 clinical trial results of the promising Covid-19 vaccine of Johnson & Johnson are expected this month. The Dutch electron microscopy facility NeCEN helped develop the company’s vaccine, and they have now published their scientific findings in Nature Communications.

Cramming from a book, making notes or learning summaries. In the past these were about the only ways to memorise your course material. But that has long since changed. Multimedia is the code word. But is it effective?

As an international employee at Leiden University, it can be hard to settle into the workplace, the city, or generally, the Netherlands. The Leiden International Centre can help international employees land comfortably and make living abroad just a little bit easier. Jenny Willcock, coordinator at the…

Imparting students with a critical attitude and cross-curricular skills. That is what Rawi Ramautar wants to strive for as the new programme director (OD) of the bachelor of Bio-Pharmaceutical Sciences. 'A programme director has to create a programme of which students say: I find it challenging and…
