RMKRB3A5–Over the course of three days (Mar. 5-7, 2012), a single, large active region blasted out over a dozen solar flares. STEREO (Behind) spacecraft caught the action in extreme UV light. Saving the best for last, it erupted with an X5 flare (X is the largest category) and a storm of charged particles as part of a coronal mass ejection. We'll be tracking this region around the far side of the Sun with STEREO and be ready if the Sun's rotation carries the existing activity back into view around March 28th.

Foraminifera are amoeba-like, single-celled protists (very simple micro-organisms). They have been called ‘armoured amoebae’ because they secrete a tiny shell (or ‘test’) usually between about a half and one millimetre long. They get their name from the foramen, an opening or tube that interconnects all the chambers of the test. Fossilised tests are found in sediments as old as the earliest Cambrian (about 545 million years ago) and

RMK1FB8E–Using the direct fluorescent antibody (DFA) staining technique, this photomicrograph depicts the histopathologic characteristics associated with a case of amebic meningoencephalitis due to Naegleria fowleri parasites. Naegleria fowleri infects people when water containing the ameba enters the body through the nose. This typically occurs when people go swimming or diving in warm freshwater places, like lakes and rivers. The Naegleria fowleri ameba then travels up the nose to the brain where it destroys the brain tissue. Image courtesy CDC/Dr. Govinda S. Visvesvara, 1980.

PROTOZOA 183 The amoeba, like other one-celled organisms, reproduces by the process of fission. A single cell divides by splitting into two others, each of which resembles the parent cell except that they are of less bulk. When these become the size of the parent amoeba, they in turn each divide. This is a kind of asexual repro- duction. When conditions unfavorable for life come, the amoeba, like some one-celled plants, encysts itself within a membranous wall. In this condition it may becom
