^{Ca2+ ATPase}

^{Ca2+ ATPase is a protein which enables active transport of Ca2+ across the membrane of cells. This active transport allows the cells to maintain a low concentration of Ca2+ ions in the cytostol which is important for proper inter-cellular signalling.}

^{Hydrolysis of ATP is the powerhouse for this process, as it allows the binding of Ca2+ ions with a ratio of one ATP hydrolysed for each Ca2+ ion bound.}

^{Here you can see Ca2+ATPase in a cellular membrane.}

The Fermi Gamma-ray Space Telescope orbits Earth with a complicated motion. This map shows the position of a particular pulsar (the Vela pulsar) inside the field of view of the telescope as it orbits around the Earth rocking north/south; rolls to keep its solar panels facing the Sun; and processes around its axis once ever 54 days. It is a compound of these three motions that gives rise to this image.

Designing my firs ever muppet-style puppet to eventually flesh out in fur, fleece and foam! This is the official CRITTER design, what “Miss Critter” is all about.

Now to choose a color…

STILL WORKING

Although, I finally got my Map printed! Not exactly ‘done done’ but close enough that it looks finished! I’ll still work on it though …later.
