Houseplants Can Improve Air Quality Indoors, But By How Much?

Share This Post

If you live or work in a small, poorly ventilated space, consider getting a few potted plants. Although they don’t really help reduce carbon dioxide levels, houseplants remove significant amounts of nitrogen dioxide (NO2), which can weaken one’s respiratory system. Some houseplants that researchers have found to have this striking ability are the peace lily, dragon tree, and ZZ plant. They were found to have reduced peak NO2 concentrations by 20% in a small, poorly ventilated space, while larger and better-ventilated areas have reduced effects. Read full article here

AI Predicts Crime A Week In Advance With 90 Per Cent Accuracy

An artificial intelligence model built by Ishanu Chattopadhyay and his colleagues analysed crime data in Chicago from 2014 to 2016 and managed to predict future levels of crime down to the nearest 300 metres, a week before they actually happened. While extremely useful, this artificial intelligence has been shown to expose racial prejudice in law enforcement. Hopefully, as the study’s data and methodology have been made available for others to evaluate, these prejudices can be avoided in the next iteration. Read full article here


Automated Identification Of Chicken Distress

Did you know that chickens make distinct sounds when they’re stressed? Chicken raisers painstakingly identify these calls manually to figure out how their chickens are faring—a sort of state of the chicknation, if you will. However, those days of manual identification might be nearing an end after a group of researchers developed an AI primed to identify stressed chicken noises. Called light-VGG11, the AI seems like a promising solution for those with large flocks of chickens after it accurately identified chicken distress calls among other recorded chicken calls.
