Summary

Story summary

Researchers at Saitama University identify the DmMSL10 chemical ion channel as essential for Carolina-native Venus fly traps' touch sensitivity.
The channel amplifies weak electrical signals from touch, enabling leaves to close on prey.
Engineered traps lacking DmMSL10 show reduced responses to stimuli.
In a lab ecosystem, ants closed more traps with DmMSL10 than without.
