Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Agate is a microcrystalline variety of quartz, chiefly chalcedony, cryptocrystalline form of silica.  Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks but can be common in certain metamorphic rocks. Most agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly  by siliceous matter deposited in regular layers upon the walls.

The protein responsible for Alzheimer's disease has recently been identified. It has been suggested that plaques formed by amyloid-β sheets may interfere with transmission at neuronal synapses. This image uses images of the plaques and the atrophied brain caused by Alzheimer's disease as a backdrop to illustrate the horror of the disease and the realistic phenomenon in vivo.
