As part of budget deal, Congress blocks light bulb efficiency standards

"Unfortunately, efficiency for small items is one case where the free market doesn't typically work. Individually, light bulbs draw very little power, and replacing one won't make any notable difference in a consumer's monthly bills. In addition, the replacement bulbs are more expensive up front and take years to pay off. As a result, there's unlikely to be rapid adoption of more efficient technology, leading to an extended period of wasted energy. By repealing the standards, Congress has ensured that the waste will go on even longer."

If it didn't work, I could write a short, snarky post dismissing it as hokum. If it did work, my eyes would be more comfortable.

Gold Nanoparticles Transform Trees Into Street Lights

"Street lights are an important part of our urban infrastructure — they light our way home and make the roads safe at night. But what if we could create natural street lights that don’t need electricity to power them? A group of scientists in Taiwan recently discovered that placing gold nanoparticles within the leaves of trees, causes them to give off a luminous reddish glow.
