Pete the Plant is a maidenhair fern living in the Rainforest Life exhibit at the London Zoo, but Pete the Plant isn't like other plants. Pete the Plant is also a budding photographer. Scientists in the Zoological Society of London's (ZSL) conservation tech unit has been teaching the plant how to take selfies.

The ZSL held a competition in partnership with Open Plant, Cambridge University, and the Arribada Initiative for the design of a fuel cell powered by plants. Plant E in the Netherlands produced the winning design. The prototype cell creates electricity from the waste from the plant's roots. The electricity will be used to charge a battery that's attached to a camera. Once Pete the Plant grows strong enough, it will then use the camera to take a selfie. Not too bad for a plant.

"As plants grow, they naturally deposit biomatter into the soil they're planted in, which bacteria in the soil feeds on – this creates energy that can be harnessed by fuel cells and used to power a wide range of conservation tools," Al Davies, ZSL's conservation technology specialist, explains.

Christina Hunger, 26, is a speech-language pathologist in San Diego, California who believes that "everyone deserves a voice."

"If dogs can understand words we say to them, shouldn't they be able to say words to us? Can dogs use AAC to communicate with humans?" she wondered.
