How chromosomes shape up for cell division

EMBL scientists have shown how overlapping loops of DNA stack upon each other in dividing cells to give rise to rod-shaped chromosomes.

27 October 2020 Microscopic image of a cell, nucleus visible in bright green, cell membrane stained with a purple dye against black background.

Party at the nucleus?

The nucleus of this cell fluoresces in bright green thanks to GFP-labelled nucleoporin proteins. EMBL scientists use engineered nucleoporins as 3D reference standards to improve super-resolution microscopy.

Fishing games gone wrong

When an egg cell is being formed, the cellular machinery which separates chromosomes is extremely imprecise at fishing them out of the cell’s interior, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have discovered. The unexpected degree of trial-and-error…

Intelligent microscopy

The sight of a researcher sitting at a microscope for hours, painstakingly searching for the right cells, may soon be a thing of the past, thanks to new software created by scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Presented today in Nature Methods, the…

Better imaging from bench to bedside

From microscopy to computer tomography (CT) scans, imaging plays an important role in biological and biomedical research, but obtaining high-quality images often requires advanced technology and expertise, and can be costly. Euro-BioImaging, a project which launches its preparatory phase today,…

Each of these large images of dividing cells is composed of several microscopy images of human cells in which different individual genes were silenced. The smaller images are placed according to genes’ effects: images for genes that affect chromosomes make up the chromosomes (red/pink), while the mitotic spindle (green) is composed of images for genes that affect it.
