Spatial Data Objects. The geometry and geography data types support sixteen spatial data objects, or instance types. However, only eleven of these instance types are instantiable; you can create and work with these instances (or instantiate them) in a database.
Rewiring the grain. Metabolic engineering. Golden Rice technology is based on the simple principle that rice plants possess the whole machinery to synthesise Î²-carotene, and while this machinery is fully active in leaves, parts of it are turned off in the grain.
They figured out that the golden color was caused by a single change in one gene (called a mutation). It turns out that humans have a gene that is similar to the one changed in golden fish. To test whether this gene does the same thing in humans and fish, scientists put the human gene into golden fish.
