Lucia is celebrated each year on 13th December, with a choir consisting of Lucia herself (wearing candles in the hair), terns, staffans, nomes and other creatures. This year Lucia did not show up at the Biology Department, but the traditional beverages and ginger cookies were consumed as usual. Also members of the flight lab participated in the celebrations, taking a break from a brain-storming activity during the weekly lab-meeting. What should we like a new PIV-system to do for us? - that is the question.
