High in the Swiss Alps and the Arctic, scientists have discovered microbes that can digest plastics–importantly, without the need to apply excess heat. Their findings, published this month in the journal Frontiers in Microbiology, could one day improve plastic recycling. It's no secret that plastic pollution is a big, global issue. Since its production exploded during and after World War II, humans have created more than 9.1 billion tons of plastic–and researchers estimate that less than one tenth of the resulting waste has been recycled. To make matters worse, the most common recycling option–when plastic is washed, processed and turned into new products–doesn't actually reduce waste: The recycled materials are often lower quality and might later end up in a landfill all the same. Researchers are looking for solutions to the plastics problem. One process they've experimented with is breaking down plastics using microorganisms. Enzymes from the microorganisms found in the Arctic and Swiss Alps ... were able to break down biodegradable plastics at 59 degrees Fahrenheit. "These organisms could help to reduce the costs and environmental burden of an enzymatic recycling process for plastic," co-author Joel RĂ„thi [said]. Of the total 34 types of microbes examined, 19 were successfully able to break down a form of plastic called polyester-polyurethane, and 17 could break down two types of biodegradable plastic mixtures.

Stefano Mancuso is a pioneer in the plant neurobiology movement, which seeks to understand "how plants perceive their circumstances and respond to environmental input in an integrated fashion". Mancuso teaches at the University of Florence, his alma mater, where he runs the International Laboratory of Plant Neurobiology. He has written five bestselling books on plants. "Communication means you are able to emit a message and there is something able to receive it, and in this sense plants are great communicators. If you are unable to move, if you are rooted, it's of paramount importance for you to communicate a lot," [said Mancuso]. "Plants are obliged to communicate a lot, and they use different systems. The most important is through volatiles, or chemicals that are emitted in the atmosphere and received by other plants. It's an extremely sophisticated form of communication, a kind of vocabulary. Every single molecule means something, and they mix very different molecules to send a specific message. My approach to studying consciousness in plants ... started by seeing if they were sensitive to anaesthetics and found that you can anaesthetise all plants by using the same anaesthetics that work in humans. This is extremely fascinating. We were thinking that consciousness was something related to the brain, but I think that both consciousness and intelligence are more embodied, relating to the entire body."
