Paint-on solar cells developed Posted: 21 Dec 2011 06:13 PM PST Imagine if the next coat of paint you put on the outside of your home generates electricity from light -- electricity that can be used to power the appliances and equipment on the inside. Scientists have just created an inexpensive "solar paint" that uses semiconducting nanoparticles to produce energy.

Astronomers discover rare galaxy at dawn of time Posted: 21 Dec 2011 06:12 PM PST Astronomers have discovered that one of the most distant galaxies known is churning out stars at a shockingly high rate. The blob-shaped galaxy, called GN-108036, is the brightest galaxy found to date at such great distances and is 12.9 billion light-years away.

Breakthrough in treatment to prevent blindness Posted: 21 Dec 2011 11:07 AM PST A new study shows a popular treatment for a potentially blinding eye infection is just as effective if given every six months versus annually. This randomized study on trachoma, the leading cause of infection-caused blindness in the world, could potentially treat twice the number of patients using the same amount of medication.

Astronomers discover deep-fried planets: Two Earth-sized planets around dying star that has passed the red giant stage Posted: 21 Dec 2011 11:03 AM PST Two Earth-sized planets have been discovered around a dying star that has passed the red giant stage. The discovery marks the first known case of planets surviving being engulfed by their parent star and may shed new light on the destiny of stellar and planetary systems, including our solar system.

Single cell endoscope: Researchers use nanophotonics for optical look inside living cells Posted: 20 Dec 2011 12:40 PM PST Researchers have developed a nanowire endoscope that can provide high-resolution optical images of the interior of a single living cell, or precisely deliver genes, proteins, therapeutic drugs or other cargo without injuring or damaging the cell.
