During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).

A consortium of researchers from the Leiden Institute of Physics (LION), the Institute of Biology Leiden (IBL), and the Leiden Institute of Chemistry (LIC) received a FOM program grant to develop a novel way of studying individual proteins inside a cell using gold nanorods.

What are the genes and molecular mechanisms involved in bacteria-mediated plant drought tolerance?

Donald Trump’s re-election: it could become reality after the November 2024 elections. According to various experts across Europe and the US, Europe needs to prepare for the potential implications of this scenario for European security. Professor Luuk van Middelaar, an expert in European Law, discussed…

The year 2023 saw the earthquake in Turkey and Syria, the Wagner Group rebellion and wildfires and floods as all the weather records were smashed. Our most-read stories were about the climate crisis and the elections: here’s the list.

History student Mitchell Wiegand Bruss is taking part in the water council elections. Whereas until recently he had no idea what the governing body stands for, he now wants to create awareness among other students about the political body.

Physicist Daniël Geelen has developed a new microscope that uses low-energy electrons. Those are less harmful to biological and organic materials. Geelen defends his PhD thesis on May 31st.

This thesis describes the synthesis, analysis of various tetrazine bearing compounds and use in bioorthogonal chemistry.

China is a one-party regime, yet elections are held for the local congresses. PhD candidate Wang Zhongyuan investigated how the Communist Party uses this democratic instrument to strengthen the authoritarian regime. PhD defence 31 January.

Professor Joke Bouwstra has been elected as member of the Koninklijke Akademie van Wetenschappen (KNAW, The Royal Dutch Academy of Sciences). This is a very prestigious recognition and a great honor for Joke. You can find the announcement by the KNAW below (short version) and as an attachment.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

We investigate the molecular basis underlying health and disease and provide answers to existing and emerging health problems. Within this theme, we study diseases ranging from rare genetic disorders to cancer and infectious diseases. We make use of a wide variety of model systems and pursue diverse…
