Cooking up clear, UV-proof glasses
PENN STATE (US)—Adding cerium oxide to phosphate glass rather than the commonly used silicate glass may make eye glasses that remain colorless, block ultraviolet light, and have increased resistance to radiation damage. (more…)

Move over trees. Here comes the sun
Scientists are exploring new ways to tap the sun’s energy directly, without the help of plants, to create potential fuel sources. “The main problem with current solar power technology is that if the sun’s not shining, you’re out of luck,” says Tom Meyer. “Solar fuels give us the ability to collect and stockpile that energy.”

Solar cells nano-inked onto rooftops
A team of engineers is using nanoparticle “inks” (as shown here) to develop cheap solar cells. Lead researcher Brian Korgel says the inks, which are semitransparent, could help realize the prospect of having windows that double as solar cells.
