Fish, amphibians, reptiles, and birds make them in a similar organ called the interrenal gland. Like all steroid hormones, glucocorticoids and mineralocorticoids produce effects by docking with receptors on the cell's membrane surface or inside the cell in the liquid cytoplasm. Binding in either location triggers different chemical signaling systems.
SPACEWAR. A space-combat simulation game for the PDP-1 written in 1960-61 by Steve Russell, an employee at MIT.SPACEWAR was inspired by E. E. Doc Smith's Lensman books, in which two spaceships duel around a central sun, shooting torpedoes at each other and jumping through hyperspace.MIT were wondering what to do with a new vector video display so Steve wrote the world's first video game.Steve now lives in California and still writes software for HC12 emulators. SPACEWAR aficionados formed the core of the early hacker culture at MIT.PACEWAR was inspired by E. E.

Spacewar! worked perfectly well from the test word switches on the console, except that the CRT was off to one side, so one player had a visual advantage. More to the point, with two excitable space warriors jammed into a space meant for one reasonably calm operator, damage to the equipment was a constant threat.imilarly, the torpedoes were not quite consistent with the Spacewar! universe after the heavy star was in place. The gravity calculations for two ships was as much as the program could handle; there was no time to include half a dozen missiles as well.
