Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Full size digital screening mammogram of a new breast tumor in the retroareolar region of the right breast causing nipple retraction. An ultrasound guided biopsy was performed diagnosing invasive ductal carcinoma. This is the most common type of breast cancer, accounting for nearly 80% of cases. Breast cancer treatment has come a long way in the last few decades, seeing more funding than any other human disease. The first step to a cure is catching it early with screening mammograms such as this case so that the tumor can be removed before it spreads (metastasizes) out of the breast.
