At first glance, this may look like the latest view from a telescope, but it was taken by looking not out at the vastness of space, but into a human cell. What could pass for stars or distant galaxies are actually gates to the genome that is locked up inside the cell's nucleus, as imaged by a super-resolution microscope.
By combining images of thousands of these gates, called nuclear pore complexes, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have solved a decade-old controversy over how the pieces that form each pore's ring are arranged.
