Perhaps most surprising of all, in addition to offering a different way to think about mechanisms of disease, these findings shed light upon the behavior of familiar inert condensed substances that remain poorly understood, including pastes, foams, emulsions, and granular m...Bumblebees copy one another when contending with unfamiliar flowers
Researchers have reported findings that offer a surprising new twist to our understanding of how bumblebees, a vital floral pollinator, select the flowers from which they collect nectar.

(Kingston, ON) Seabirds are the surprising culprits in delivering pollutants through their guano to seemingly pristine northern ecosystems, a new Canadian study shows.
