A team of European astronomers under Leiden leadership has discovered that dust particles around a star already coagulate before the star is fully grown. These agglomerated dust particles are the first step in the formation of planets. The research publish their discovery in the journal of Nature As…

An international team of astronomers, with researchers at Leiden Observatory playing a leading role, has mapped the fuel for galaxy formation in the iconic Hubble Ultra Deep Field. The results of the research have been accepted for publication in The Astrophysical Journal.

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

The Dutch cabinet formation – a process that has now been underway for five months – is at a standstill for the time being. Formation discussion leaders Elbert Dijkgraaf and Richard van Zwol are due to publish their report in mid-May. Wim Voermans, Professor of Constitutional Law, updates listeners…

Brain activity changes as people age, which can lead to cognitive decline. By measuring and comparing brain data from mice and humans, the researcher will investigate how the brain’s noise levels change with age and affect choice behavior.

Knowledge and culture subproject 4:

Cognitive decline (amongst other problems with attention, concentration, memory) is a common symptom in patients with a variety of brain disorders and has been related to healthy ageing as well. People suffering from cognitive deficits are often significantly hampered in their day-to-day functioning…

The effectiveness of the skin barrier underlies the outer layer of the skin: the stratum corneum (SC). However, in several skin diseases this barrier is impaired. In two inflammatory skin diseases, atopic eczema and Netherton syndrome, an increased level of monounsaturated fatty acids (MUFAs) has been…

‘It was a discovery we did not expect,’ says Remko Offringa, professor of Plant developmental genetics. Today he publishes a new trait of a versatile gene in Current Biology: it makes the difference in plants between herbaceous and woody stem growth. A useful feature to prevent dehydration.

When a star is born in our Galaxy, it is quite likely that it has formed within a massive cluster, which hosts numerous high-mass stars bathing their lower mass neighbours in UV radiation.

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

Developmental considerations in the design and delivery of cognitive-behavioural therapy for adolescent school refusal

Pieter Omtzigt, leader of the ‘Nieuw Sociaal Contract’ (‘New Social Contract’) party, has withdrawn from talks to form a new Dutch government. Government finances are a divisive issue, and Ronald Plasterk’s decision to withhold documents on government finances seems to have particularly broken trust.…

This thesis examines the link between simple molecules and the underlying structure and chemistry within protoplanetary disks - the birthplaces of planets.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

My work focuses on a class of astronomical objects called protoplanetary disks.

As humans we have a tendency to judge certain actions as either right or wrong. Where does our moral sense come from? We found evidence that infants who are only one year old prefer those who comfort as opposed to ignore another who is sad.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

The ALMA Local Expertise Group (Allegro) is located in the Leiden Observatory (Sterrewacht). Professor Ewine van Dishoeck: ‘The Netherlands has played an important role in establishing ALMA. Thanks to this subsidy, we can now reap the scientific benefits.'

Syntacticians study how words combine into larger units (phrases and sentences) in human languages and how the combinatorial possibilities determine word order and grammatical relations between parts of a sentence.
