All spiders spin silk, with glands that produce custom blends of proteins with different "motifs" that impart just the right properties—toughness, flexibility, stickiness, etc.—for a wide range of uses. Different silks make up distinct parts of a web, for example. Other are used to wrap prey or encase eggs. As this graphic shows, the silks exit the abdomen through spigots on so-called spinnerets.

The Biomedical Use of Silk: Past, Present, Future
TLDR
This progress report provides a critical but detailed insight into the biomedical use of silk, including the development pipeline of this new industry for clinical use.
Spider-web inspired multi-resolution graphene tactile sensor.
TLDR
Graphene with porous and densely-packed microstructures to integrate into a multi-resolution graphene tactile sensor that can integrate discrepant electronic properties with remarkable flexibility will attract enormous attention for electronic skin, wearable devices and human-machine interactions.
