Using solar and astronomical image processing techniques and mathematical theory we have developed novel image analysis techniques to track the growth of tumours and other cell-based structures, which can be crucial for advancements of therapeutics to treat diseases such as cancers.
The visual similarities between coronal mass ejections and the outward invasion of cells from a tumour spheroid are striking. This study aims to help us better understand changes in the tissue architecture which are associated with tumour growth.

One can notice the depth of the ocean floor, on a global scale, ranges between -2000 and -6000 meters. In some regions though like the Pacific exceed this range and reach 11 kilometers below the sea surface. One such region is the deepest point on Earth, the Mariana trench as shown below followed by a map for a perspective of its location.

The Photograph shown is the raw image with no alterations. The image depicts a flat plate wing, which is simultaneously pitching and translating rapidly over a short distance through water at a Reynolds number of 10,000. This work is targeted towards understanding the aerodynamics of small insects with an intended application for Micro-Air Vehicles. The vortices are visualised by injecting a dye composed of milk and water. The milk has good reflective properties and is neutrally buoyant so follows the real flow faithfully. The inspiration for using milk came while pouring milk into a cup of tea at breakfast one morning! The photograph was taken by myself using a Nikon D7000 digital SLR camera, with the shutter speed and ISO adjusted to maximise the light entering the camera and allow the vortex structures to have a high contrast against the background. There are reflections of the vortex structures on the surface of the wing and some air bubbles are also visible on the dye injection needle on the wing’s surface.
