Het begrijpen van de wereld om ons heen hangt af van het vermogen om de wereld te ontleden in verschillende objecten en deze in hun geheugen op te slaan. Dit proces wordt gedefinieerd als object individuatie. Onderzoek wijst uit dat dit voor baby’s niet altijd gemakkelijk is.

Als mensen hebben we de neiging om bepaalde handelingen als goed of fout te beoordelen. Waar komt ons morele besef vandaan? We hebben bewijs gevonden dat baby's van slechts één jaar oud de voorkeur geven aan degenen die troosten in plaats van negeren wanneer iemand verdrietig is.

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

At the moment, over 350.000 chemicals are registered worldwide for production and use. Their application, however, may harm human health and the environment.

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…
