Master's Open Day at UNU-MERIT
UNU-MERIT will host a Master’s Open Day on Saturday 7 October 2017. Our top-ranked MSc in Public Policy and Human Development (MPP) emphasises the connection between public policy and decision-making processes, as well as the principles of good governance.

Students who successfully complete our Master’s programme receive a double degree issued by the United Nations University and Maastricht University. Several information sessions will be offered throughout the day and visitors will have the opportunity to talk with staff and students.

    New research on how bees perceive colour could be put to good use in our digital cameras, meaning photos shot by drones or phones would look more natural than ever.

    It's all to do with colour constancy, the way that bees (and humans) can tell a flower is red no matter what the colour or quality of the light - a mental trick that the digital cameras of today really struggle with.

    Researchers from RMIT University in Australia found that bees are using two colour receptors in their ocelli, the three extra eyes on the top of the head, that judge the colour of ambient light, in combination with two main compound eyes that detect flower colours more directly.

    In the past it was thought bees might use some kind of chromatic adaptation, like humans, to make colour constancy corrections. It's similar to adjusting the white balance on a photo to correct for the ambient light. What the new research suggests is that bees are doing something different: the scientists traced neural activity from the ocelli, discovering that information was passed to the key colour processing areas of the bee brain.

    Those three tiny upward-facing eyes measure the light coming from the sky and can make adjustments accordingly, correctly identifying flower colours. The team then set down some mathematical principles behind this mix of data from the ocelli and compound eyes, principles which could eventually be used to program the same trick into a smartphone camera or an exploratory robot.

    As well as making your pictures look more realistic in unusual lighting situations, this model could help robots trek through sunlight and shade without getting confused about what they're looking at.
