Caspase-1 initiates apoptosis, but not pyroptosis, in the absence of gasdermin D
Caspase-1 triggers programmed necrosis called pyroptosis by gasdermin-D (GSDMD) cleavage.

A new way of making complex structures in thin films
Self-assembling materials called block copolymers, which are known to form a variety of predictable, regular patterns, can now be made into much more complex patterns that might someday be useful for making optical or plasmonic devices (in which electromagnetic waves interact with electrons), according to an MIT study.
