Elon Musk’s Biggest Worry 26 April 2022
A brief history of artificial intelligence 30 August 2021

In the summer of 1956, a group of researchers set out to try to reproduce human intelligence in a machine. More than sixty years later and despite enormous progress, that goal is still out of reach. Just how far, nobody knows.
An introduction to artificial intelligence for a new publication series put out by Aventine, a non-profit research institute that studies how rapid technological advancements and disruptive change will affect life in the decades to come.

Room-temperature superconductivity has been achieved for the first time 15 October 2020

It was in a tiny sample under extremely high pressure, so don’t start dismantling the world’s energy infrastructure quite yet.
Room-temperature superconductors—materials that conduct electricity with zero resistance without needing special cooling—are the sort of technological miracle that would upend daily life. This is a short news story about the first announcement of their fabrication.
