The article describes how spider silk is a really strong material, stronger than steel and kevlar. Not enough spiders to produce silk commercially so must make it themselves by inserting spider silk proteins into goat cells. When goats become pregnant the material is spun. So it provides a description of the process and a description of the motivation for studying it.
It's using comparisons to already existing materials, right down to the molecular structure of the material. The development is following bunch of steps, like in a recipe.
The perspective is that of someone who is interested in the development of technology from someone who is educated and reporting on someone else's work. It describes the researchers' hopes for where their work is going.
I'm not syure the thesis is strong, though. They talk about making stringer materials but to what end do they need such materials is not explained. The sources are university researchers reporting in a journal.
