Yeast cells before (left column) and after (right column) protein knockdown. In each row, a different representative of a protein family (marked in green) was knocked down that was found to shape the structure of mitochondrial organelles (marked in purple). In total, 220 different proteins were discovered whose absence causes structural disruptions in these essential organelles.

Secrets, cracks and fractures

It turns out that the shorter a crack in brittle materials - the more resistant they are to it, which can help in the design and use of applications that are based on brittle materials
