Spider Silk Protein Forms Amyloid‐Like Nanofibrils through a Non‐Nucleation‐Dependent Polymerization Mechanism

open access: yesSmall, Volume 19, Issue 46, November 15, 2023., 2023
Both spidroin and Alzheimer's disease associated amyloid‐β peptide capped by spidroin terminal domains can assemble into silk‐like fibers that consist of straight nanofibrils in normal physiological‐like buffer. Spidroins′ unique primary structures have evolved to allow functional amyloid‐like properties, and at the same time direct their ...

Sexual selection and predation drive the repeated evolution of stridulation in Heteroptera and other arthropods

open access: yesBiological Reviews, Volume 98, Issue 3, Page 942-981, June 2023., 2023
ABSTRACT Acoustic and substrate‐borne vibrations are among the most widely used signalling modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs generating acoustic sound and/or substrate‐borne vibrations, and are fundamental to our broader understanding of the evolution of animal signalling.

Global expansion of a solitary‐social tropical spitting spider shaped by multiple long‐distance dispersals

open access: yesEcography, Volume 2023, Issue 3, March 2023., 2023
The spitting spider Scytodes fusca is a species complex well known for its unusual hunting technique which involves spitting a venomous sticky silken substance over its prey. Previous studies supposed that S. fusca was native to Central and South America but had expanded to the tropics of almost every continent.
