A new way to analyze human reaction times shows that the brain processes data no faster than 60 bits per second.
The optional solar roof on Toyota’s 2010 Prius may not provide a watt of mobility.
If electric cars become popular quickly, the demand for charging them is likely to exceed supply. Now mathematicians have worked out how electricity companies can distribute their power fairly to car owners. But the price–accurate information about driving habits–may be too much to ask.
