    Here is the @Cornell Chronicle article about our @PNASNews paper on the evolution of milkweed toxins (N,S-cardenolides), to which the monarch butterfly is sensitive, despite being co-evolved with milkweeds!
    Cornell researchers have uncovered a new strategy milkweed uses to fight monarchs: upgrading the structure of its toxins.

    Wow wonderful discovery on how small changes in olfactory receptors of the agricultural pest Drosophila suzukii explain the shift to prefer laying eggs in ripe fruit instead of overripe fruit due to better detection of ester fruits volatiles 🤩 Huge congrats @hdweck99 and Dr Xue

    I am very happy to share that the latest work from the lab, led by Dr. Qi Xue (@Qi_Xue_94), has been published in PNAS and is now online: pnas.org/doi/10.1073/pn…

    My first podcast 😅 on how decoding the smell of organisms could help us to find solutions to protect crops in agriculture, and improve plant, animal, and human health by detecting diseases before symptoms appear! @Cornell @CornellEnto @CornellAgriTech
