Risk-taking and sensation-seeking are typical behaviour for adolescents. Research by Leiden psychologist Barbara Braams and her colleagues published in NeuroImage shows that the social context also plays an important role.
A consortium including Leiden University has been awarded 12 million euros for their participation in the design of the Square Kilometre Array (SKA). The SKA will be the world’s largest and most powerful radio telescope.
On an excavation site in Oegstgeest Leiden University archaeologists discovered a very rare silver bowl from the first half of the seventh century.

People from an ‘honour culture’ often respond more aggressively to insults and provocations than those from a ‘dignity culture’. Saïd Shafa examined the underlying mechanisms and discovered how such responses can be avoided. PhD Defence 26 June.
When learning to read and do arithmetic it is important for a child to be able to remember instructions and complete assigned tasks. The development of these sorts of functions is a good predictor for reading and arithmetic skills, concludes Neely Anne Davidse. Hyperactivity and lack of concentration do not necessarily mean a child should spend longer in infant school. Dissertation defence on 25 June.
In five years, South Africa should have access to a wide range of scientific information, raw material for determining what direction the country needs to move in. Leiden University is participating in the Centre of Excellence (CoE) set up especially for science and innovation. Leiden professor Robert Tijssen: ‘We are going to produce a clear picture.’
Lecturers are not always successful at integrating research into their teaching, despite the popularity of this trend around the globe. Is that sort of integration always desirable and possible? PhD candidate Yanjuan Hu interviewed Dutch and Chinese lecturers and found that they did not differ much from each other. Dissertation defence on 26 June.
Evolutionary biologist Menno Schilthuizen looks for evolutionary patterns behind asymmetric forms in animals. In practically no animal is the left half exactly the same as the right half.

History can be found in utensils and in interviews with ordinary citizens. ‘With the reconstruction of everyday life, an anthropological approach works better,’ thinks historian Jan-Bart Gewald. Inaugural lecture on 6 June.
Leiden PhD student Sreenivasa Ramaiahgari is the first person to develop a 3D model of the liver. His model could result in big savings: in terms of damage to patients, animal suffering and a lot of money.
Of the four Spinoza prizes this year, two have been awarded to Leiden scientists: physicist Dirk Bouwmeester and archaeologist Corinne Hofman. This was announced by the NWO on 6 June during the Bessensap science event in Utrecht.
The Lisbon Treaty (2007) was partially intended to bolster the European Union’s democratic legitimacy. But regulations are increasingly originating from the European Commission, an institution with no democratic mandate. This is what Leiden legal scholars Wim Voermans and Josephine Hartmann write in the Journal of Theory and Practice of Legislation.
Researchers and students in Journalism and New Media at Leiden University have presented a study on Europe in the Dutch media. Their report was published just two weeks before elections for the European parliament.
Soil bacteria can produce a wealth of antibiotics that are new to us, claims Gilles van Wezel. His group has developed a method that can rapidly identify and produce these unknown compounds. In Chemistry & Biology (Cell Press, online from 8 May) the researchers demonstrate that the approach works.
Can online treatment benefit patients with chronic physical disorders? Cognitive behavioural therapy via internet has been shown to be effective. Health psychologist Sylvia van Beugen writes in the 'Journal of Medical Internet Research' about the effects of Ehealth therapy for physical disorders.
Archaeologist Wil Roebroeks and his American colleague Paola Villa dispute the validity of the arguments for the supposed inferiority of Neandertals to modern humans.
