XXY versus autism: evidence from neuroimaging
Brain development in children with an extra X chromosome as compared to children with autism: evidence from MRI

Self-interest versus group interest
People are less willing to give up an interest when in a negotiation situation than when they can do it of their own free will, as Leiden University psychologist Eric van Dijk discovered. Knowledge of this kind can be used by policy makers, for instance, to motivate people to adopt certain desirable…

Wild versus domestic prey in the diet of tigers
A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

Digiuseppe & Poast, ‘Arms versus Democratic Allies’
In theory, states can gain security by acquiring internal arms or external allies. Yet the empirical literature offers mixed findings: some studies find arms and allies to be substitutes, while others find them to be complements. Political scientists Matthew Digiuseppe (Leiden University) and Paul Poast…

Young suns and infant planets: Probing the origins of solar systems
Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

European Lone Actor Terrorists Versus “Common” Homicide Offenders: An Empirical Analysis
The term “Lone Actor” has been applied to a variety of violent individuals who are thought to act out of ideological motivations using terrorist tactics.

Rubicon for ‘Artificial Sun’
Physicist Christopher Berg Smiet, who recently obtained his PhD in Leiden, has been awarded an NWO Rubicon. The grant allows him to conduct postdoctoral research for two years at the Princeton Plasma Physics Laboratory (PPPL) in the United States.

Marc Stevens and colleagues reveal weak spot in internet security
Marc Stevens, PhD student of Ronald Cramer, and colleagues have found a weak spot in internet security. As a consequence of this weak spot in the infrastructure of digital certificates forged certificates can be issued that can be fully trusted by the usual web browsers. The results have been presented…

Giant planet at large distance from sun-like star puzzles astronomers
A team of astronomers led by Dutch scientists have directly imaged a giant planet orbiting at a large distance around a sun-like star. Why this planet is so massive, and how it got to be there, is still a mystery. The researchers will publish their findings in the journal Astronomy & Astrophysics.

Ab Initio Molecular Dynamics Calculations versus Quantum-State-Resolved Experiments on CHD3 + Pt(111): New Insights into a Prototypical Gas–Surface
The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

AI versus corona
It’s all hands on deck at the moment to resolve the COVID-19 crisis. Researchers from various disciplines are helping where they can, also from the field of artificial intelligence (AI). AI offers great opportunities both at the frontline of the crisis and in its expected aftermath. Leiden professor…

Cheering for the sun at the Leiden Observatory
Staring into the clouds hoping for a glimpse of the sun, cheering in encouragement, video recordings: there was no shortage of things to do at the Leiden Observatory. More than 600 visitors witnessed the last, almost complete solar eclipse of the decade..

Chemical bond versus electromagnetic waves
Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the chemical bond at the surface thereby appears to be less important than previously…

Protostellar jets and planet-forming disks: Witnessing the formation of Solar System analogues with interferometry
The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

What are we defending? Steven Pinker on the core values of NATO and the Enlightenment
NATO not only safeguards our security and stability, but also defends Enlightenment principles, promoting prosperity, health and freedom. This is what eminent psychologist and thinker Steven Pinker argued to a packed Great Auditorium.

Traces of building block of life found around infant suns
ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate - a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery…

‘The sun never sets on our university'
Leiden University has partnerships in the local region, in the Netherlands, in Europe and with countries on almost all the world's continents. Students and researchers benefit from these partnerships, but society is also a beneficiary, says Rector Carel Stolker.

Dynamics of the Oort Cloud and Formation of Interstellar Comets Santiago Torres Rodriguez
The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.
