The taming of fire, permitting the thermal processing of vegetable foodstuffs in particular, extended enormously the number of natural products that could be used as foods by humans and gave a tremendous impulse to the extraordinary dif￾fusion and development of the human population in almost every region of the world (De Bry, 1994). Foodstuffs can be roughly divided in two classes, those that are or are not edible in their raw form. The most important naturally edible foods are meat and milk, which are heated mainly for eliminating dangerous microorganisms, and some fruits, used by plants to attract animals for diffusing

Human Visual Orientation in Weightlessness Charles M. Oman Man Vehicle Laboratory, Massachusetts Institute of Technology, Cambridge, MA 02139 Abstract: An astronaut's sense of self-orientation is relatively labile, since the gravitational “down” cues provided by gravity are absent and visual cues to orientation are often ambiguous, and familiar objects can be difficult to recognize when viewed from an unfamiliar aspect.

Skeletal Consequences of Spaceflight Background Early flights: very little idea of physiological changes to expect -big concerns: respiration, cardiovascular -bone probably wasn't a serious consideration What has been learned in the past 37 years of human spaceflight?
