How an herbivore hijacks a nutrient uptake strategy of its host plant  

Maize plants release secondary metabolites into the soil that bind to iron and thereby facilitate its uptake by the plant. The Western corn rootworm (Diabrotica virgifera), the economically most important maize pest worldwide, is attracted by these complexes, extracts the bound iron from the maize plant and uses it for its own nutrition. With these insights, researchers provide a new explanation for the extraordinary success of the Western corn rootworm as a global maize pest.

Novel research optimizes both elasticity and rigidity in the same material without the usual tradeoffs  

In the world of materials, rigidity and elasticity are usually on opposite ends of the continuum. Typically, the more elastic a material, the less able it is to bear loads and resist forces. The more rigid it is, the more prone it is to rupture at lower strains when the load or force exceeds its capacity. A goal for many materials scientists is to create a material that brings together the best of both worlds.
