Weird news: Scientists have taught spinach plants to send emails, and it could warn us about climate change

It may sound like something out of a futuristic science fiction film, but scientists have managed to engineer spinach plants which are capable of sending emails, according to a news piece published by Euronews.com.

Through nanotechnology, engineers at MIT in the US have transformed spinach into sensors capable of detecting explosive materials. These plants are then able to wirelessly relay this information back to the scientists.

When the spinach roots detect the presence of nitroaromatics in groundwater, a compound often found in explosives like landmines, the carbon nanotubes within the plant leaves emit a signal. This signal is then read by an infrared camera, sending an email alert to the scientists.

This experiment is part of a wider field of research which involves engineering electronic components and systems into plants. The technology is known as “plant nanobionics”, and is effectively the process of giving plants new abilities.

“Plants are very good analytical chemists,” explains Professor Michael Strano who led the research. “They have an extensive root network in the soil, are constantly sampling groundwater, and have a way to self-power the transport of that water up into the leaves.”

“This is a novel demonstration of how we have overcome the plant/human communication barrier,” he adds.

“Plants are very environmentally responsive,” Strano says. “They know that there is going to be a drought long before we do. They can detect small changes in the properties of soil and water potential. If we tap into those chemical signalling pathways, there is a wealth of information to access.”
