Summary

Story summary

UC Riverside researchers exposed fruit flies to hypergravity, finding 4 G increased activity while 7 G, 10 G and 13 G suppressed it.
Ysabel Giraldo reported that a 24-hour 4 G exposure kept flies hyperactive for up to 80 days before fading.
Ten generations under high gravity showed movement deficits without clear genetic adaptation, with flies exhibiting altered brain energy decisions and fat storage, according to Arumugam Amogh.
