How are supermassive black holes born? That is the question astronomer Elena Maria Rossi is trying to answer. But how do you investigate something you cannot see?

‘There is no such thing as a timeless Japanese soul,’ says newly appointed Professor in Modern Japan Studies Katarzyna Cwiertka. The first month of her professorship turned out to be a crucial test: Japan was hit by a destructive earthquake and tsunami, and Cwiertka had to keep her head in the midst…

For many a first-year, student life has well and truly begun. This also applies to students in The Hague, who were thrown in at the deep end during the HOP introduction week. We paid them a visit on a sunny afternoon at Landgoed Clingendael.

Sander Kok (35) was a hit as a model for Armani and he is now making a name for himself as a writer. His philosophically tinted first novel 'Smeltende vrouw' was acclaimed as a literary sensation. How do Literature Studies and Art History benefit him today?

For a number of years, two ‘boxes’ in the Canary Islands and Chile have been scouring the skies for exoplanets that orbit bright stars. PhD candidate Geert Jan Talens helped develop these ‘MASCARA’ telescopes and has made the first discoveries with them. Together with him, we answer the main questions…

Astronomers and surgeons from Leiden are collaborating with industry to develop an optical instrument that delivers faster, more accurate imaging of tumour tissue and abnormal blood flow during surgery.

A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

Whether finding signals of dark matter or discovering hydrogen in the vicinity of exoplanets, Leiden astronomers are world players in their field, and they are part of a long tradition: Leiden was the first university in the world to have its own observatory.

It is a warm day. The sun is shining brightly while biologist Marco Roos makes his way through the bushes towards a peculiar little plant. Insects buzz, birds chirp. In the background rises the LUMC: at the Bio Science Park in Leiden, people and nature come together in a special way.

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.

When the government introduced its corona measures, the future of EL CID suddenly looked uncertain. But this annual introduction week will start on 5 August after all. How did the EL CID board pull this off? A glimpse behind the scenes through the eyes of chair Mirte Haanappel.

Lecturers had a week to convert their courses to online teaching. An enormous challenge because remote teaching definitely wasn’t commonplace at Leiden University, and some lecturers have to share their ‘lecture hall’ with their children or partners. Alexander Pleijter, a lecturer in Journalism and…

Our lecturers had just a week to convert their lessons into online formats. It was an enormous challenge because by no means everyone at Leiden University was involved in online teaching. Professor of Korea Studies Remco Breuker has found that doing everything on line takes a lot more time. 'I've also…

To read Chekhov in the ‘original’. That was what motivated Arie van der Ent to study Slavic languages and literature with Karel van het Reve at Leiden University. ‘My love for Chekhov hasn’t faded,’ says Van der Ent from his home 60 kilometres south of Kyiv. ‘But it has for the rest of Russia.’

How has evolution shaped our curiosity? And how does that curiosity ensure that we now have the technological ability to discover whether we are alone in the universe? This was all covered during the celebration of Leiden University’s 449th Dies Natalis.

Wouter Moerland is on a two-year secondment as ecology adviser at the Municipality of Leiden. This biology alumnus talks animatedly about his work. ‘We’re working hard to increase nature’s chances in town.’

The new academic year is on its way and for most students it takes some getting used to being present at the KOG every day. What about international students? We spoke with three internationals who have been studying at Leiden Law School since this academic year.

Imagine we could do what green plants can do: photosynthesis. Then we could satisfy our enormous energy needs with deep-green hydrogen and climate-neutral biodiesel. Scientists have been working on this for decades. Chemist Chengyu Liu will receive his doctorate on 8 June for yet another step that brings…

The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic. As a result, researchers cannot predict with confidence where they will be in about 462 years. ‘That is astonishingly short,’ says astronomer Simon Portegies Zwart who collaborated on the r…

Many primary school children suffer from anxiety and their numbers are increasing. Psychologists from the Knowledge Center Anxiety & Stress (KAS) are developing and researching preventive training.

Her new book, Rebels and Conflict Escalation,…

The Dutch Research Council (NWO) has awarded Vidi grants to Leiden researchers.

On the 442nd anniversary of the foundation of Leiden University, and at the start of the Leiden Asia Year, lawyer Jan Michiel Otto, an expert in the field of law in developing countries, delivered the first Dies lecture. He compared demagogues in Asia who call upon Muslims to turn against their governments…

Wija Wijayanto and Arum Perwitasari both were Indonesian PhD students at Leiden University, funded by the Leiden-DIKTI Graduate Scholarship Programme. With the help of this scholarship, literally thousands of students travel abroad to write their dissertations. During their research period, Arum and…

At the Faculty of Science, forty per cent of the employees are of a non-Dutch nationality. Amongst PhDs that is even sixty per cent. How are they doing in a time of working at home in a different culture, when travelling is not possible? Clinical pharmacologist Lu Chen is the third in this series to…

The first full-colour images of the cosmos from ESA's space telescope Euclid were presented today. Never before has a telescope been able to take such crystal-clear astronomical images of such a large part of the sky and so far into the deep universe. The five images illustrate Euclid's full potential;…

Following our Leiden Brussels Alumni Event, I (external officer M. Blaauw, ed.) met our very own Leiden Law alumna Helena-Loutas Paraskeva. An Australian who works for the European Commission. Interesting, how did she get this job, what does she do and how did her Master in Leiden affect or influence…

If you study law, you won’t necessarily end up striding round a law firm in tailor-made suits. Alumnus Harrie Schoffelen certainly hasn’t: he made the conscious decision to follow another path in life. Together with his fiancée he runs a successful food truck on the tropical island of Bonaire. ‘Return…

Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.

Nineteen researchers who have recently been awarded their PhD are to receive a Veni grant of up to 250,000 euros. Science funding agency NWO has awarded a total of 158 Venis in this round; Leiden University's share of the awards is 12 percent.
