Scientific methods and techniques have been employed in archaeological research since the very birth of the discipline. It is impossible to imagine modern archaeology without this expertise in archaeological sciences. These archaeological sciences take centre stage in the new temporal exhibition at…

Planet formation is a surprisingly homogeneous process that does not take place gradually from inside out, but that occurs everywhere at the same time in a proto-planetary disc, as Dave Lommen has discovered. He will obtain his doctorate this week based on his research into the dust around young stars…
