• There has been a sharp plunge in the population of honey bees, which pollinate about 70 percent of global crops, or one-third of food that humans eat including fruits and vegetables, raising fears over food security.
  • The tiny sensors, which are lighter than pollen that bees collect, allow researchers to analyze the effects of stress factors including disease, pesticides, air pollution, water contamination, diet and extreme weather on the movements of bees and their ability to pollinate.
  • "We're also investigating what key factors, or combination of factors, lead to bee deaths on mass. The sensors, working in partnership with Intel technology, operate in a similar way to an aeroplane's black box flight recorder in that they provide us with vital information about what stress factors impact bee health." Gary Fitt from Australia's national science agency CSIRO told AFP.
