What started as an idea during a social gathering led to an unexpected breakthrough in research on resistant bacteria. Biologists and chemists from Leiden developed a new substance that proves to be effective against bacteria resistant to antibiotics. They published their discovery in Nature Chemist…

Nathaniel Martin, Professor of Biological chemistry, wondered what would happen if you take an antibiotic that has been known for 70 years and try to improve it with the latest tools of modern chemistry. Turns out it can become up to a hundred times more potent and prevent the growth of some drug-resistant…

For the first time, it was shown in living cells how the bacterium E. coli regulates genes that help it survive in a new environment. Biochemist Fatema Zahra Rashid managed to do this using a technique she fine-tuned. Her research into changes in 3-dimensional chromosome structure offers clues for ways…

It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden PhD candidate Samuel Schwab has found that the histones in these organisms are much more diverse than previously thought. Schwab and his colleagues describe…

Not experiments and lab coats, but computers and artificial intelligence: this year's Nobel Prize in Chemistry went to the inventors of the groundbreaking AI model, AlphaFold. This programme accurately predicts protein structures based on their genetic code—a crucial step in understanding biological…

Archaeologist Tuna Kalayci investigates roads in a recent edited book. What happens if we think of roads not only as containers of action but also as dynamic and complex phenomena, as the action itself? This question inspired Dr Tuna Kalayci to bring together various studies across a wide range of epochs…

Dr. Joris Larik, Assistant Professor at LUC The Hague, has been selected for a fellowship at the Netherlands Institute for Advanced Study (NIAS) in Amsterdam. During his fellowship, Larik will conduct research on a fundamental question: Was Brexit worth it when it comes to striking trade deals around…

The English taught interdisciplinary minor Violence Studies looks into various facets of interpersonal violence. Is this minor for all Leiden students? These two 'colleagues' are certain of it.

Four researchers from Leiden University will receive funding from arthritis foundation ReumaNederland over the next five years. This should facilitate long-term research into arthritis.

Why do some people with adverse childhood experiences develop mental health conditions whereas others do not? A Leiden research project is looking for volunteers aged between 18 and 24 to help us understand more about human resilience.

The European Commission has selected a consortium of major European launcher and satellite manufacturers, operators and service providers, as well as policy and legal research centres and institutes to study and provide guidelines and recommendations on Space Traffic Management (STM). The IIASL of Leiden…

It was while wearing clogs at a Dutch theme park in Japan that Cindy Heijdra really got to know Japan. Over 20 years later, she is studying again: to be a primary school teacher.

Despite considerable progress in the design of multifunctionalized nanoparticles (NPs) that selectively target specific cell types, their systemic application often results in unwanted liver accumulation. The exact mechanisms for this general observation are still unclear.

On Tuesday 12 January 2021, the Leiden Law School thesis prizes were awarded at the New Year’s event.

Chronic pain, nausea or vomiting due to chemotherapy. If you suffer from such ailments, medicinal cannabis can be a godsend. Though a downside is that it can make patients high. Therefore, Leiden researchers from the Oncode Institute are investigating alternatives that do not make you high. In Nature…

What role did inequality play in the past? On Friday 5 December, Master's students in history presented their answers at a conference they organised themselves.

The more than 370 sensors that have been hung up in Leiden University buildings to count the people present will not be switched on again. The equipment will eventually be removed from the buildings.

How do opinions form and change in large groups of people? That's not just a sociological question, it's a mathematical one. PhD candidate Federico Capannoli studied opinion dynamics. He defended his thesis on November 19.

When hobby divers revisited a nearly 400-year-old shipwreck off the coast of Texel, they discovered more than 1,000 objects in wooden boxes. Eight years later, postdoc Janet Dickinson used recovered books to compile a profile of the mysterious owner.

Ambroise Paré, Thomas Sydenham and Herman Boerhaave: all were great medical innovators in their time. We know far less about the 19th-century Russian physician and scientist Nikolay Ivanovich Pirogov. PhD candidate Inge Hendriks researched him in Dutch and Russian archives and collections. She discovered…

There seem to be genes that influence how our brains develop over time. A large international consortium has discovered this with an extensive study. The results of the study were recently published in Nature Neuroscience.

Prison and student life are worlds apart. But in the Learning Behind Bars project, Leiden criminology students get the chance to study inside prison walls with people incarcerated there.

The Choose a Language Day was created to make high school students enthusiastic about choosing a linguistic profile and further education. Third-years were able to learn about different language studies at the Faculty of Humanities.

To increase the accuracy of climate models, it is crucial that they include past human land-use and human-driven vegetation changes. Here archaeology can make an important contribution. Current models are based on reconstructions of past vegetation. However, their accuracy is limited because it does…

For two decades, language experts were certain that babies were able to learn language rules from as young as the age of seven months. However, recent research carried out by a consortium of four Dutch baby labs led by researchers from Leiden cast doubts on this certainty. We spoke to researchers Andreea…

Ambassador Hyoung Chan Choe of South Korea paid his first visit to Leiden University Nov. 22, where he was received by President Annetje Ottow and Professor of Korea Studies Remco Breuker.

At the Leiden Institute for Area Studies (LIAS), scholars have been studying the Indian subcontinent with attention and expertise for more than 100 years. This part of South Asia is an economic giant with a population of over two billion. Nira Wickramasinghe, Professor of Modern South Asian Studies,…

A major new study of ancient DNA has traced the movement of people into southern Britain during the Bronze Age. In the largest such analysis published to date, scientists examined the DNA of nearly 800 ancient individuals. Publication in Nature on December 22, 2021.

Some bacteria, it turns out, have proteins much like ours that organise the DNA in their cells. They just do it a bit differently. This is revealed by new research from biochemists at the Leiden Institute of Chemistry and the Max Planck Institute for Biology. The discovery helps us better understand…

Organisations like the UN and the EU should be given more powers to combat transboundary problems. This is the message of a report published by the Swedish SNS Democracy Council, whose authors include Prof. Jan Aart Scholte of Leiden University. The researchers also wrote the following article.
