London Zoo scientists have laid the groundwork for the world’s first plant selfie – a pioneering scientific trial in the Zoo’s Rainforest Life exhibit which will try out how microbial fuel cells power a plant to take its own picture. This they hope will lead to using plants to power camera traps and sensors in the wild allowing conservationists to monitor habitats remotely.(Protesters in Hong Kong are seen wearing helmets and gas mask while looking at their phone.
