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…

Good research means looking beyond disciplinary boundaries, said Professor of Molecular and Cellular Biochemistry Remus Dame in his inaugural lecture on 10 May. Processes that take place on DNA shouldn’t only be researched in a test tube but also in living cells, for instance.

Professor Johan Rooryck will be examining cognition and core knowledge systems and how possession is expressed in different languages. Rooryck and fellow researchers have been awarded two NWO grants totalling 2.75 million euro to carry out two research programmes: 'Knowledge and Culture' and 'Lend me…

A night sky of more than 40 petabytes in size, simulating young star clusters and understanding how the body inhibits viruses: three Leiden projects have received computing time on one of the national computer systems.

One used 3D cell models to study colorectal cancer, while the other used machine learning for more efficient blood donation. For these achievements, Marieke Vinkenoog and Simon Christian Hansmann were awarded the Krijn Rietveld Memorial Innovation Award on Tuesday 2 September.

Bird, butterfly, fish: when you look through a children’s book, you usually don’t think about the fact that humans divided these animals, depicted in bright colours, into categories. Yet, this division has been discussed for centuries. In her PhD dissertation, Didi van Trijp shows how natural scientists…

While health data is essential for scientific research, that data also needs to be protected. In her doctoral thesis, Irith Kist found a balance between protecting the individual and exchanging health data.

The Dutch Research Council (NWO) has rewarded four projects in which Leiden researchers are bringing science and society closer together. What are these projects?

The Clinical Epidemiology department at the LUMC has set up a series of lectures for asylum seekers. The series has become a huge success.

Individuals suffering from social anxiety disorder (SAD) consistently avoid eye contact. However, in a non-clinical population, gaze avoidance in socially anxious individuals depends on social situations, Jiemiao Chen saw in a series of experiments, for which she used wearable eye-trackers. On 25 April…

Comparing individual health data with group data allows doctors to give personalised advice and patients to learn from one another's experiences. Wessel Kraaij, Professor of Applied Data Analytics, shows how personal data can have a valuable predictive function. Inaugural lecture 24 February.

A Leiden Groningen student team has reached the European finals of the BISC-E competition. In this annual competition students have to come up with a sustainable solution to a major social problem. The team invented Suckerspheres: a natural alternative to the plastic microbeads that are still widely…

People with relatively high levels of lipids in their blood are less likely to develop allergic conditions such as eczema and asthma. These lipids cause genes that play a key role in allergic reactions to be less active. Researchers from the Leiden University Medical Center (LUMC) have published an…

Tuberculosis stands as one of the most lethal infectious diseases worldwide. A significant challenge in combatting tuberculosis lies in the emergence of antibiotic resistance triggered by genetic alterations, commonly known as mutations. These mutations can diminish the responsiveness to antibiotics,…

From artificial intelligence to letters from the Dutch East Indies and from breast-cancer gene BRCA-1 to the collaboration between government and opposition: nine researchers from Leiden University have been awarded a Vidi grant for their research.

Students who have a chronic lack of sleep have lower grades and find it harder to concentrate. Around a third of students do not feel well rested enough to be able to study properly.

Paco Barona Gomez is the newest associate professor at the Institute of Biology Leiden (IBL). The Mexican researcher is fascinated by the evolution of natural products: compounds made by microbes, but also plants and animals. ‘It’s like we investigate chemical dark matter.’

Parents’ talk about new stimuli such as persons or objects strongly affects how avoidant or fearful their child will react. No stronger effect was found when parents had an anxiety disorder or in children with fearful temperaments. Publication by a team of Leiden psychologists in 'Clinical Child and…

LUCL is pleased to announce that Professor Johan Rooryck has been awarded both an NWO Horizon Grant for his project entitled 'Knowledge and culture', and an NWO Vrije Competitie Grant for his project entitled 'Lend me your ears: the grammar of (un)transferable possession' for a total of €2.75m.

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…

Archaeological finds off the coast of Java, Indonesia provide insight into the world of Homo erectus, 140,000 years ago. Skull fragments and other fossil remains provide a unique picture of how and where these early humans lived, says Leiden archaeologist Harold Berghuis.

Aisha Hassan came to the Netherlands when she was two months old. Her mother had fled Somalia and made a new home here. Aisha doesn't remember much about that time, but her mother’s stories about Somalia ignited a lifelong interest in developing countries. ‘Her stories have always fascinated me.’

Newts of which half of the offspring die before birth. Evolutionary biologist Ben Wielstra is investigating how this can exist in nature. In his research he collaborates with Naturalis Biodiversity Center.

Different groups of hominins probably learned from one another much earlier than was previously thought, and that knowledge was also distributed much further. A study by archaeologists at Leiden University on the use of fire shows that 400,000 years ago knowledge and skills must already have been exchanged…

‘A challenging rollercoaster, but also a very bonding and insightful experience,’ that’s how the team of iGEM Leiden 2022 wraps up their participation in the iGEM contest. The contest for synthetic biology climaxed during the Grand Jamboree in Paris. The team ended up in the top 10 of over 360 teams…

A child who receives fewer nutrients in the womb than their identical twin brother or sister is more likely to have developmental problems later in life. This is what researchers from the Leiden University Medical Center (LUMC) write in The Lancet Child & Adolescent Health. This study shows that unfavourable…

An international group of scientists has discovered that certain cells of our immune system – the so-called T cells – communicate with each other and work together as a team. To fight an infection they stimulate each other’s growth, but at the same time, they inhibit each other when there is a surplus…

A new LUMC study has changed our understanding of how cells work. Researchers have discovered that the CFAP20 protein acts as a kind of ‘traffic controller’ on DNA. Without this protein, chaos ensues, potentially causing cancer. Their findings have been published in the prestigious journal Nature.

Leiden researchers have found clues to why a rare pregnancy disorder is mild in some babies but life-threatening in others. Their discovery opens the door to a test that could identify severe cases during pregnancy. Fortunately, a treatment already exists.

Ben Wielstra strives to unravel the evolution of balanced lethal systems. On 1 February he started his own lab at the Institute of Biology Leiden. Wielstra is one of five researchers at Leiden University who has been awarded an ERC Starting Grant in 2018 by the European Research Council. ERC Starting…

Evidence that the right diet can prevent or alleviate depression is weak. In literature reviews on the subject, the authors often reach strong conclusions, nonetheless. This is what Florian Thomas-Odenthal, a master’s student in Psychology at Leiden University, discovered in his thesis research. Publication…
