Dear Reader, Hi, I'm health and medicine editor Tanya Lewis, filling in for Sunya Bhutta. In today's newsletter, we've got a story about how plant hormones (yes, plants have hormones!) can help respond to stressors such as pests or drought and how tweaking them could improve the food supply. We also have an article about the mystery of why the orbit of Saturn's moon Titan is expanding slightly each year. Finally, we have a piece about NASA's newest Mars rover, whose mission is to bring back rocks from the Red Planet and eavesdrop on Martian sounds.
