Acetate is a very common chemical compound that you can find in vinegar and hair care products. Aside from making our food taste good and keeping our hair lush, it may also be the key to growing food without sunlight. Researchers discovered that crops like lettuce can use pure acetate to synthesise their food without sunlight. How? Well, acetate formed from carbon dioxide and carbon monoxide through electrochemical processes is both a carbon and energy source; normally plants use sunlight as an energy source to transform carbon into food.
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
