The Cribellate Nanofibrils of the Southern House Spider: Extremely Thin Natural Silks with Outstanding Extensibility

Advanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
Nanofibrils are considered the universal building blocks of spider silks. In this work, the thinnest natural spider silk nanofibrils are imaged, measured, and mechanically tested for the first time. Gaining insight into the mechanics of silk at the nanoscale is important.

Ecological trait divergence over evolutionary time underlies the origin and maintenance of tropical spider diversity

Ecography, Volume 2025, Issue 4, April 2025.
Relative to its size, tropical Asia is likely to be the richest region in terms of biodiversity. However, the factors of species diversity formation and maintenance in Southeast (SE) Asia and neighboring regions remain poorly understood. Here we infer the evolutionary relationships within psilodercid spiders by incorporating fossil information into a ...
