Bumblebees carry up to seven times more toxic metals than honeybees, even when feeding in the same fields; study finds |

Bumblebees may be carrying a far heavier burden of toxic metals than honeybees, even when both species forage in the same countryside. The research found that pollen collected by bumblebees contained between two and seven times higher concentrations of several harmful metals, including arsenic, chromium, lead and tin, compared with pollen gathered by nearby honeybees.

Honeybees just helped scientists build tiny drones that navigate without GPS and find their way home |

Most drones rely on GPS and powerful computers to find their way around. That makes them heavy, expensive, and power-hungry, basically not practical for anything small. But honeybees? They navigate perfectly with brains smaller than a grain of rice. Now, scientists at Delft University of Technology have figured out their secret and built drones that […]
