What does the evidence actually tell us about insect sentience?
Join us on March 11 as @viveknityananda.bsky.social examines frameworks for investigating insect welfare, including key debates around insect emotions and pain.

Come hear me stir up some controversy* next month with my take on the evidence for insect sentience.

Netcasting spiders modulate silk thread stiffness via a tailorable multi-fibre meta-structure to construct a web that is hyperelastic and high load-bearing at the same time.

Multiple anthropogenic stressors can negatively impact species but can a single stressor also have multiple, concurrent impacts? Here we show that light pollution creates several simultaneous impacts to the nocturnal movement ecology of a moth and a spider: tinyurl.com/5eku5bff (1/5)

Meet our Plenary Speaker Daniela Rößler
Fueled by curiosity and a deep love of natural history Daniela discovered a REM-like sleep state in spiders and uses integrative field, lab and comparative approaches to investigate the function, ecology, and evolution of sleep across the spider tree of life.
