    Feb 1 2026

    TWiV reviews the finding in Sweden that immunization against cervical cancer with human papillomavirus vaccine also protects the non-immunized, and methyl salicylic acid as a key volatile molecule that attracts parasitoid wasps to rice and other crops to destroy destructive leafhoppers, and is down-regulated by virus infection to enable virus spread.
