In one of the projects they took smallpox, which has otherwise disappeared from the world, and found a way to genetically introduce into it, without reducing its efficacy as smallpox, either Ebola virus or equine encephalitis viruses. Nobody seems to know what happened to those experi .....

.... as energy reserves also. It provides a quick-release energy source that keeps us going between meals. Small amounts of carbohydrates are also used for structural purposes and others are attached to outer surfaces of cell membranes to guide cellular interactions. For many cells, sugars are the most important source of energy. Lipids are important because they function as structural components of cell membranes, sources of insulation, and a mean of energy storage. The lipid molecules are most well known as forming basic structures of cell membranes and as energy storage molecules as well. In this group of lipids, there are about three main .....

It is used, on Earth, for those who's hearts have problems with pumping blood. Pens that write upside-down are used in space, where there is no gravity and writing with pens would otherwise be impossible.
