Summary

Story summary

Australian researchers led by Fiorella Ramirez-Esquivel showed bee stingers pump venom via dual pistons.
High-speed cameras captured alternating piston motion in a gel that mimics skin.
The valve system maintains continuous venom flow for up to 15 minutes after detachment.
Researchers built a mechanized model reproducing the pumping behavior, suggesting micro-pump designs.
The study was published in the Proceedings of the National Academy of Sciences on Monday.
