The discovery raises the possibility that researchers could increase crop yields by inserting a gene that encourages crowded crop plants to flourish in shade cast by neighboring plants.

Blacksuburg, Va. -- Some caterpillars can adjust the color of their chrysalids, or pupae, from brown to green to camouflage them in their environment, so it's no wonder butterflies have evolved to mimic toxic butterflies to save themselves from predators. In Batesian mimicry, non-toxic butterflies ...At last: Just three cell types detect light in the eye
