Incredibly ancient supermassive black holes have stumped scientists since their discovery. Their rate of growth seemed impossible according to current knowledge. But a team of researchers suggest that perhaps collapsing dark matter halos — invisible matter surrounding galaxies that make up the bulk of its mass — create massive seed black holes. These baby black holes then feast upon the remaining gas and stars once bound together by the dark matter halos and grow into supermassive black holes.

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
