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…

Archaeology is also digging with computers. This digital quest to find out how we humans lived in the past is what Karsten Lambers likes doing most. He is the first Professor of Digital and Computational Archaeology in the country. ‘A dream come true.’

Leiden researchers, led by Sebastian Pomplun developed a new method to screen hundreds of thousands of molecules for drug discovery, using mass spectrometry instead of DNA tags. ‘We wanted to make drug discovery faster and more accessible.’

For the first time, we’re seeing what Euclid sees. The telescope’s initial observations have provided a wealth of new information about our universe. But according to cosmologist Alessandra Silvestri, this is just the beginning. The research helps us gain a deeper understanding of the past, present,…

To streamline all these new initiatives and create new student well-being activities, a Student Well-Being Officer has recently…

17 November is all about high tech. From consultations with ASML and a component for the world's largest telescope to our high-tech education. Oh right, and a conversation with the new rector magnificus.

Did he dare take a gamble with his PhD research? Jeroen Methorst didn’t have to think long about it. It could fail or turn out very well. The latter is the case. Methorst developed a computer system that helps researchers find the protein they need. ‘Our whole group is now using this program.’ Methorst…

Registering your hypothesis and analysis plan online before starting your study – why should researchers bother? Henk van Steenbergen, a researcher in cognitive psychology, decided to give it a try. 'I used it as an exercise in open science.'

Over the past few years, citizen scientists from the Heritage Quest project have scoured the entire Veluwe and Utrechtse Heuvelrug areas for unknown archaeological heritage. One of the results of this research is that the number of known burial mounds in this area has doubled.

Maak kennis met digitale veiligheid in de podcast over de BSc Cybersecurity & Cybercrime. Experts bespreken actuele thema’s zoals ransomware en online fraude.

It often takes longer for women with heart problems to get the right diagnosis. In her Annie Romein-Verschoor Lecture, Professor Hester den Ruijter will talk about how hormones influence the heart and the importance of medical research that focuses specifically on women.

More severe droughts that will also last longer: this will primarily be a problem for irrigated croplands, as discovered by environmental scientist Qi Chen. Mixed forests with a variety of plant species will be the least vulnerable. Chen compared the effects of drought on different ecosystems across…

Dutch mosquitos are more resilient to saltwater than previously thought. Environmental scientist Sam Boerlijst discovered this during his PhD research at the Hortus botanicus. This knowledge is crucial for understanding how mosquito-borne disease transmission might change in the future.

Learn how silence can benefit your well-being during Work Stress Week from 11 to 15 November. It’s no surprise that we sometimes need a bit of peace and quiet, says Professor of Auditory Culture Marcel Cobussen. ‘Our brain is exposed day and night to auditory stimuli.’

How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

Seven Leiden professors have been elected as members of the Royal Netherlands Academy of Arts and Sciences (KNAW). In total 23 new members will be inaugurated on Monday 13 September.

Early diagnosis, new treatments, and personalised care: all of these are possible if we can better unlock the wealth of information hidden in health data. Unfortunately, this data is often poorly organised, difficult to access, and not interoperable. The new international Leiden Institute for FAIR and…

Jasper Knoester is the dean of the Faculty of Science. How is he doing? What kinds of things is he doing and what does his day look like? In each newsletter Jasper gives a peek into his life as dean.

Alumnus José Figuerero tells us about how a Criminologist can work at Booking.com and why he would have liked to have had more law-related courses in his master's programme.

Aram Segaar, Corporate Information Security Officer in the Information Management Department, works every day with his team to create and maintain a secure working environment at Leiden University. October is ‘Cybersecurity Month’. Aram explains how the university stays safe and the conscious (and unconscious)…

Crucial information about research, funding or how university rankings are created is often not freely accessible. The Barcelona Declaration on Open Research Information calls for such information to be made open. Professor Ludo Waltman is one of its initiators. What needs to change?

In the MS Cognitietour, psychologists and neuroscientists from Leiden University discuss the latest scientific knowledge with MS patients and their loved ones. This leads to insights: 'One lady told how much stress she felt from all those caregivers around her bed.'

Imagine scanning lion dung or a mouse dropping and instantly knowing exactly what and how much the animal has eaten. Thanks to new DNA techniques, this is becoming increasingly feasible. PhD student Kevin Groen tested how effective these techniques are at unraveling the diets of wild animals.

Leiden Observatory has achieved a rare feat: two of its research teams have been awarded prestigious ALMA Large Programmes, allowing them to study how galaxies formed and evolved in the early Universe using cutting-edge telescope observations.

An international team of astronomers led by Dutch scientist Martijn Oei has discovered the largest pair of jets from a black hole ever seen. The 'jumbojets' extend a combined length of 140 Milky Ways. The Leiden Observatory played a prominent role in this research. The publication will feature on the…

If a forged Vermeer or Rembrandt is discovered, it is world news. Yet tracing fakes has long been a low priority in art history. University lecturer Anna Tummers will receive an ERC grant of almost two million euros to change that.

A pandemic of lianas is sweeping through tropical forests, reducing their ability to store carbon and limiting their role in mitigating climate change. Two recent studies from Leiden University highlight the issue. ‘We now understand why lianas are visible in satellite imagery.’

For the first time, an international group of astronomers have seen the heat glow of two ice giant planets colliding. They could also observe the resultant dust cloud move in front of the parent star several years later. Led by Leiden astronomer Matthew Kenworthy, they monitored the star's brightness…

How did early humans use their hands, and what can that tell us about our shared past? Cora Leder, newly awarded recipient of the NWO PhD in the Humanities grant, is set to find out.
