A new kind of light bulb

March 26, 2015 8:25 am | by Univ. of Southern California | News | Comments

How many researchers does it take to change a light bulb? And how many lives could they save by changing it? The answer to both questions is larger than you might expect. In the developing world, light bulbs might as well be insect magnets. The light they emit, particularly the blue wavelengths of LED lights, is attractive to a range of insects, drawing them out from the night and straight to people's homes.

Sewage could be a source of valuable metals, critical elements

March 23, 2015 8:42 am | by American Chemical Society | News | Comments

Poop could be a goldmine, literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys. Now researchers are looking at identifying the metals that are getting flushed and how they can be recovered. This could decrease the need for mining and reduce the unwanted release of metals into the environment.
