Imagine a construction site where the bricks are individual molecules and the "cranes" are microscopic needles so sharp they can feel a single atom. For decades, building at this scale was a laborious, time-consuming task ...

As proteins are made in a cell, they are folded into the 3D structure that allows them to work, but sometimes this process can go wrong. When it does, the misfolded proteins lose some or all of their function and usually ...
