This is my super spectacular (mostly) space blog!! I also enjoy math, Doctor Who, Supernatural, Cowboy Bebop, Fullmetal Alchemist, jellyfish, Detroit, Futurama, and cats.

Blank Slate
29 creeping into more numbers and still not a third of the way in. hopefully. building upon shaky foundations and seeing the choices made...

Couple more sweet Comic Con scores.

Le Birthday presents :D although I still have to more yet to come
Red blood cells and platelets. Coloured scanning electon micrograph (SEM) of human erythrocytes (red blood cells) and a platelet aggregate (purple). Platelets are fragments of white blood cells that under normal circumstances are small and biconcave in form. However, if there is a break in the surface of a blood vessel the platelets come into contact with molecules they are not used to and become activated. They become amorphous in form, with long projections (pseudopodia) that help them adhere to other cells and each other, forming a clot. Magnification: x4000 when printed at 10 centimetres wide.

Malaria infected red blood cell. Coloured scanning electron micrograph (SEM) of a erythorocytes (red blood cells). The cell at upper right is misshapen due to infection with a Plasmodium falciparum protozoan. This is the merozoite stage of the protozoan parasite. It invades red blood cells after the sporozoite stage is injected into the blood by an Anopheles mosquito. The merozoites replicate and destroy the red blood cell, causing anaemia. They may then invade more red blood cells, causing the severe cyclic fevers of malaria. The infected red blood cells may clot and block blood vessels. Magnification: x7,000 when printed at 10 centimetres wide.
Ruptured venule. Coloured scanning electron micrograph (SEM) showing stacks (rouleaux) of red blood cells exposed inside a torn venule. A venule is a very small blood vessel in the microcirculation that allows deoxygenated blood to return from the capillary beds to the larger blood vessels (veins). Red blood cells are the most abundant cell in the blood. They have no nucleus and are about 7 micrometers across. Magnification: x2300 when printed at 10 centimetres wide.
Blood cells. Coloured scanning electron micrograph (SEM) of red blood cells (erythrocytes) and a white blood cell (leucocyte, pink, upper centre). Red blood cells are biconcave, disc-shaped cells that transport oxygen from the lungs to body cells. They circulate around the body in the blood and also remove carbon dioxide to the lungs for exhalation. Their red colour comes from the oxygen-carrying protein haemoglobin. Red blood cells are the most abundant cell in the blood. They have no nucleus and are about 7 micrometres in diameter. White blood cells perform functions ranging from cleaning up cellular debris, to defending the body against bacteria and other pathogens.
