The quantum computer: it doesn't exist yet, but still we understand increasingly better what problems it can solve
How do we know what a quantum computer is good for when it hasn't been built yet? That's what PhD candidate Casper Gyurik investigated by combining two terms you often hear: quantum computing and machine learning.

Special telescope measures neutrino with highest energy ever
Even with state-of-the-art technology, it is almost impossible to see: a cosmic neutrino. Yet scientists have managed to image this particle with a deep-sea telescope. And that could help to better understand our universe. Leiden particle physicists collaborated on this ambitious project, published…

Ineke Sluiter: ‘Accessibility, diversity and inclusion are a matter of doing the right thing’
For two years, Ineke Sluiter was president of the Royal Netherlands Academy of Arts and Sciences (KNAW). Now, she is returning to the university full time. ‘I always carry themes like accessibility, diversity and inclusion with me.’

FLAMINGO: dark matter, ordinary matter, and neutrinos in the biggest cosmological simulation ever
Not only dark matter, but also ordinary matter and dark energy are tracked in the largest ever cosmological computer simulation ever. In the FLAMINGO simulations, you can see virtual galaxies and clusters of galaxies emerging over the course of billions of years. This is no easy task: with more than…

Looking for atmospheres in the ultimate quest for extraterrestrial life
To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations.…

Space telescope Euclid makes first test images - astronomers are full of anticipation
The two instruments of ESA's space telescope Euclid have taken their first test images. The first images indicate that the space telescope will achieve the scientific goals for which it was designed - and possibly much more. Euclid will create a 3D map of a third of the sky, allowing scientists to study…

How can academics be supported in the face of threats on social media?
'Academics who share their knowledge with the outside world on social media are often insulted or even threatened. Especially female academics and academics of colour seem to regularly be the victim of sexist and racist comments.' This is what Ineke Sluiter, Professor of Greek Language and Literature…

How minority governments could benefit the Netherlands
Minority governments only become an option when attempts to form a government collapse. PhD candidate Corné Smit explored why such governments have become rare in the Netherlands and what advantages they might offer. ‘Broad majority coalitions often fail to make substantial progress on key issues.’

A blue or gold background? NICAS grant awarded for research on restoration
Should the background of the painting remain blue or be restored to its original gold colour? PhD candidate Liselore Tissen will be using 3D prints and eye-tracking software to answer this question. NICAS is giving her a grant of 18,000 euros to accomplish this.

Real-life data ask for strong algorithms: Mitra Baratchi designs them
How do we deal with large sources of greenhouse gases? Do schools provide a socially-inclusive environment for all children? And how can we protect Earth’s nature? These questions have two things in common: they are complex global challenges, and data can help answer them. Mitra Baratchi is computer…

Widespread cultural diffusion of knowledge started 400,000 years ago
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…

New research reveals link between finger tapping and Alzheimer's
Suddenly getting lost, failing to recognise family members, or forgetting words and names are well-known symptoms of Alzheimer's disease. Psychologists have now discovered that the disease also manifests in more subtle ways: through the rhythm of finger tapping.

Algorithms descend into our sewers to improve inspections
They never cross our minds until, that is, they become damaged and then they’re a huge problem: our sewers. Their maintenance could be much faster and more accurate, PhD candidate Dirk Meijer has discovered. Algorithms are also proving to be a godsend deep underground.

Using AI to track greenhouse gas emissions
PhD candidate Julia Wąsala searches for greenhouse gas emissions in satellite data. As a computer scientist, she bridges the gap between computer science and space research. ‘We really can't do this research without collaboration.’

Motion of stars near Milky Way's central black hole is only predictable for few hundred years
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…

Managing chronic pain? ‘With a data driven approach you can tailor treatment to the individual’
Exercising less, skipping parties and struggling at work: the expectation of chronic pain and itching can lead to avoidance behaviour. But this is by no means the case for everyone with chronic pain, as PhD candidate Gita Nadinda discovered. What does this mean for healthcare?

‘Als onderzoeker leer je veel van projecten die verder reiken dan je eigen expertisegebied’
Als nieuwe hoogleraar Ontwikkelingspsychologie pleit Anna van Duijvenvoorde voor meer samenwerking in de wetenschap. Daarom moedigt ze jonge onderzoekers zich aan te melden bij een netwerk. ‘Het biedt je een bredere blik op de wetenschappelijke wereld.’

Ethics and student research: 'Students have the same questions as researchers'
When do you submit a thesis proposal to the Ethics Committee? And how do you ensure that students save their data properly? On 9 June, thesis supervisors will be able to ask these questions at the Ethics Education Afternoon. Professor Herman Paul and policy officer Marcel Belderbos will tell us more…
