Researchers from the Kavli Institute of TU Delft and EMBL Heidelberg filmed how a single protein complex called condensin reels in DNA to extrude a loop. By extruding many loops in long strands of DNA, a cell effectively compacts its genome so it can be distributed evenly to its two daughter cells. The findings were published online in Science on 22 February.

Retreating sea ice has allowed increased shipping in the harsh conditions of the Barents Sea and the Arctic Ocean. On-board safety is mainly affected by sea spray freezing on contact with the ship deck. Funded by the NWO Polar Programme, researchers from TU Delft are studying the very basics of sea spray formation.
