Netcasting spiders hurl a stretchy net to capture prey, a net that can double in size during full extension. A study explores how the silk achieves such impressive elasticity without sacrificing strength. In PNAS: https://ow.ly/qRYu50Y5z8x

Gustatory sensitivity to amino acids in bumblebee mouthparts | Royal Society Open Science Bees rely on amino acids from nectar and pollen for essential physiological functions. While nectar typically contains low (less than 1 mM) amino acid concentrations, levels in pollen are higher but variable (10–200 mM). Behavioural studies suggest ...

🚨 Our study from @bethbees.bsky.social lab is out in @royalsocietypublishing.org . We show that bumblebees taste some amino acids (valine), but not others (lysine). Bees might choose flowers not just by how sweet they taste! #bees 🐝 #taste 👅 #pollen #nectar 🌺 #protein 🥩
