Why sounds and smells are as vital to cities as the sights

When David Howes thinks of his home city of Montreal, he thinks of the harmonious tones of carillon bells and the smell of bagels being cooked over wood fires. But when he stopped in at his local tourism office to ask where they recommend that visitors go to smell, taste, and listen to the city, he just received blank stares.

“They only know about things to see, not about the city’s other sensory attractions, its soundmarks and smellmarks,” says Howes, director of Concordia University’s Center for Sensory Studies, a hub for the growing field often referred to as “sensory urbanism.”

Around the world, researchers like Howes are investigating how nonvisual information defines the character of a city and affects its livability. Using methods ranging from low-tech sound walks and smell maps to data scraping, wearables, and virtual reality, they’re fighting what they see as a limiting visual bias in urban planning.

These scientists want to capture more carbon with CRISPR crops

The news: Plants are the original carbon capture factories—and a new research program aims to make them more effective by using gene editing. The Innovative Genomics Institute, a research group founded by CRISPR co-inventor Jennifer Doudna, has announced a new program to use the revolutionary gene-editing tool on agricultural crops to boost their aptitude for carbon storage. 

How it’d work: One of the primary goals will be to tweak photosynthesis so plants can grow more quickly. By altering the enzymes involved, researchers could cut out energy-sapping side reactions, including some that release carbon dioxide. The researchers also hope they can find ways to store more carbon in the soil, for example by encouraging larger, deeper root systems. 

Bigger picture: It’ll be a significant challenge to make these techniques work, but the research is part of a growing effort by scientists to find ways to vacuum up the carbon dioxide already in the atmosphere in order to slow climate change. Read the full story.
