In our weekly news filter ‘What We’re Clicking On’, we share our thoughts on the most interesting articles relating to the future of cities, buildings and interiors.

In several cities such as Mexico City and the Dutch cities of Amsterdam and Den Bosch, air pollution is fought by ‘planting’ trees in the city. Project Via Verde has the aim to filter more than 27,000 tons of harmful gas yearly and to capture more than 5,00 kg of dust and process more than 10,000 kg of heavy metals yearly. Critics of the project state that the real problem of air pollution, excessive ownership of private cars, should be directly aimed instead. Amsterdam and Eindhoven planted CityTrees, artificial trees that filter polluted air. Other cities wait for the results before they decide to implement the technology.

Research conducted among 2,318 children in southern California, published in the journal Environmental Health shows traffic pollution is a major risk factor for the development of obesity in children. They found that by age 10, children suffering high early exposure were almost 1 kg heavier on average than those with low exposure. The study is not the first in its kind as earlier studies also linked pollution and child obesity. One of the possible ways in which polluted air can increase weight gain is through inflammation of body systems, such as the lungs. In turn, the inflammation may spill over to the brain which regulates appetite and changes in fat metabolism. Read more about this and other research in The Guardian




Cryptocurrency millionaire Jeffrey Berns (Blockchains LLC) purchased an 67,00-acre plot in the Nevada desert to found an ‘experimental community’ which revolves around crypto currency and other new technologies. Berns believes cryptocurrency Etherieum will give people a way to control their identity and online data without any governments or companies involved. The identy of every resident will be translated into an Etherieum address that will be used to vote on local measures and store personal data. By creating a real-world laboratory, Berns hopes that some of the primary problems that come with crypto communities, such as security, can be tackled. Other technologies Berns want to incorporate are 3D printing, nano technology and AI. Read & see more about the project here.
