Massimo Pigliucci on Rationallyspeaking.org asks some questions about the US Prison system and why we lock people up. This is despite violent crime in the US going down – which could have interesting causes as Kevin Drum writes on Mother Jones. Do we need to be asking the same questions in Australia? There are currently about 30,000 people in Australian gaols. That’s only 0.1% of the population but the number of people in gaol is growing at almost double the speed of population growth, even though in Australia violent crime is also down.

I often forget living in the city with its bright lights and pollution how beautiful the nights sky can be. As an example I’ve come across this video of time lapse photography at the Very Large Telescope in Chile. It’s pretty amazing. Check out Phil Plait’s blog for some commentary.
