A stick-on gel for plants could offer a simple, safe and targeted way to treat diseases and pests. It can be loaded with substances, such as medicines, and applied directly onto a plant to deliver those materials into its tissues. In tests, the gel was used to clear a plant's bacterial infection.

In this model of a 1D material, researchers demonstrate a new way to remotely change a material's stiffness using sound waves. The team was co-led by the University of California San Diego, University of Michigan, and the French National Center for Scientific Research (CNRS) at Laboratory of Acoustics of Le Mans University.
