Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.
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.

Raspberry rust is a malignant disease caused by the phytoparasitic fungus Phragmidium rubi-idaei. This pathogen forms small ulcers on the leaves through which a huge mass of orange spores breaks through. Under a microscope, this pathogen does not look so sinister.

Photomicrograph of Volvox globator, a green algae in various stages of development. Dark green spots are daughter colonies forming inside of parent colony. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. 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.
