A close-up image of a cancer cell, caught in the act of dividing, has won an international photography prize.
Dr Paul Andrews, from the University of Dundee, was one of only two winning entries from the UK in the Nikon Small World Competition.
The School of Life Sciences researcher took the photo using a digital deconvolution microscope.
A university spokesman said understanding the way cells segregate was critical for cancer studies.
Dr Andrews' image shows a cancer cell dividing its chromosomes (shown in white) into two new cells.
The international microscopy competition is open to all disciplines of science and received more than 1,700 entrants.
