Image Cache: Every year, the Wellcome Trust rounds up the best biomedical images of the last twelve months as part of its Image Awards. This year, the pictures are a reminder of just how beautiful biology can be. Browse through the cool photos, animations and diagrams in Gizmodo's Image Cache here.
There are 20 winning images in the awards this year and we've chosen a handful to show you here. Our particular favourite is the image above, which looks like it could be an aerial photo of a city -- but is in fact a fluorescein angiography image of the blood vessels in the retina of the human eye.
This next image, which looks like a Gustav Klimt painting, is a microscopic view inside the curling structure of a leaf cluster from a young maize plant.

This thermal imaging shot reveals with stark clarity the symptoms of Raynaud's disease -- a condition which causes less blood to flow in the hands and feet. The disease leads to numbness and pain, tending to occur when sufferers are cold, anxious or stressed.

Any biomedical photo collections needs something a little grizzly -- and this time it's blisters on the forearm, the result of an allergic reaction to a black henna tattoo. Standard henna is an orange-brown, but extra pigments -- in this cased used to provide a darker colour -- can sometimes give rise to extreme reactions.

This is a lone human stem cell, the image captured using cryogenic scanning electron microscopy. It's sat in a mixture of chemicals designed to replicate the conditions of the human body.
Sílvia A Ferreira, Cristina Lopo and Eileen Gentleman, King's College London
A level of Doom? Nope: This is in fact an optical coherence tomography image of inside the back of a human eye. The tunnels are actually blood vessels.
Peter Maloca, University of Basel
Not a heart of stone -- but the heart of a cow. This is a preserved specimen, stored in formalin in a Perspex container held at the Anatomy Museum of the Royal Veterinary College in London. The heart is about four times larger than a human heart, measuring about 28cm top to bottom.
Michael Frank, Royal Veterinary College
This last image looks like it could be a baggage scan of some sausages, but it's actually two rod-shaped bacteria on a thin sheet of graphene. The image was captured by chance, when non-sterile water was used to wash the surface of the graphene sheet.
