What are pollinators?

Rowers are known to employ all manner of trickery to attract pollinators, from taking the shape of an insect mate to emitting wafts of rotting flesh. A South African flower lures in its main pollinators, Desmometopa flies, with the scent of a fresh meal. The flower produces a cocktail of chemicals that mimics those released by a wounded honey bee, drawing flies into a pollen-coated chamber.

Anyone who has struggled to pinpoint his or her location in a mall, airport or urban canyon amid skyscrapers has experienced a GPS gap firsthand. In fact, the global positioning network is filled with them-, buildings, jammers and the landscape itself can block a signal’s path between GPS satellites and receivers in a smartphone or other digital device.
