Nature Science Update posted an article about an experiment showing that a perovskite (LaFe0.57Co0.38Pd0.05O3) can reduce the amount of precious metal currently used to break down harmful vehicle exhaust gases by up to 90%. Check out the article for more details, as I'm not familiar enough with this area to write about it.

It appears that new technology isn't always as useful as it appears. A similar discovery was made using a "prehistoric" transistor to produce "better than excellent" sound from a stereo system. Change is bad. ;)
