Evolution and development of flowers, fruits and inflorescences of Phalaenopsis and other orchid species
The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

Beoordeling van troostend gedrag door twaalf maanden oude baby's: een keuze-experiment
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.
