Airbnb rentals linked to increased crime rates in London neighborhoods – study

A recent study from University of Cambridge and University of Pennsylvania found a positive association between Airbnb rentals and police-reported robberies and violent crimes in thousands of London neighborhoods between 2015 and 2018. An additional 1,000 robberies per year would correspond to a 10% increase in active Airbnb rentals.

Physicists discover first “black hole triple”

Astronomers have observed a black hole triple system for the first time, featuring a central black hole consuming a star and a distant companion that orbits every 70,000 years. The discovery raises questions about the origins of the black hole itself.
