An article about extracting hydrogen from water using sunlight and a super molecule made up of ruthenium and rhodium from the Technology Review. Maybe fuel cells will become a practical reality someday.
I knew that investment in the ruthenium mine would pan out some day ;-)
This article from the Technology Review is interesting too. The Light Clock Promises Finer Time in fact it's so accurate that it won't lose a second in the lifetime of the universe.
On the practical side it may help improve the accuracy of GPS.
