Image of the Week

FEBRUARY 2018

Week 07 (18 - 24)

The image shows a colony of the Flavobacterium IR1, 2 cm in diameter, growing on a nutrient agar plate. The cells in the colony are highly organised, thus forming a 2-D photonic crystal that interferes with light. This results in structurally coloured bright and angle-specific hues with a concentric ring pattern indicating subtle changes in organisation. The older cells of IR1 in the colony centre are more disorganised and therefore loses colour. IR1 can be genetically modified from this wild-type strain to create new, living photonic structures.

During mitosis, microtubule-organizing centers assemble the spindle fibers that separate the copying chromosomes of DNA. Researchers are now trying to decipher their molecular architecture. Integrative structure model of the yeast spindle pole body core, showing the proteins: Cnm67 (green), Spc42 (blue), Spc110 (red), Spc29 (purple) and Cmd1 (yellow).

Week 04 (28 - 03)

New machine learning algorithm uncovers time-delayed interactions in cells. The Sliding Window Inference for Network Generation, or SWING, algorithm puts together a more complete picture of cause-and-effect interactions among genes.
