France’s nuclear energy spending was 60% of what Germany spent on renewables. France gets about 400 Terawatt hour per year from nuclear but Germany gets 226 Terawatt-hours each year. 45 Terawatt-hours of Germany’s renewable power comes from burning biomass which generates air pollution.
Microsoft and Warner Brothers collaborate to store and retrieve the 1978 'Superman' movie on a piece of glass roughly the size of a drink coaster.

This study examines how vehicle speed influences the probability that a pedestrian struck by a vehicle will sustain severe injuries or die.
We argue that an ideal simulation of the same task can be performed on a classical system in 2.5 days and with far greater fidelity.
