Employees of Japanese weather forecasting company Weathernews display some of the 1,000 pod-shaped pollen counting robots called “Pollen-robot”, which are ready to be shipped as nationwide monitors to observe pollen levels ahead of the coming hay fever season, at the company's headquarters in Chiba, suburban Tokyo on January 28, 2014. The Pollen-robot, which has two LED eyes and glows a range of five different colours to indicate pollen levels, will be placed outside houses and can send reports recording pollen, temperatures, humidity and air pressure to the company through the internet. The company will start to count PM2.5 particles for air polution with the pollen robots from this year. (Photo by Yoshikazu Tsuno/AFP Photo)
