Researchers split water into hydrogen, oxygen using light, nanoparticles

Posted: 15 Dec 2013 01:09 PM PST

Researchers have found a catalyst that can quickly generate hydrogen from water using sunlight, potentially creating a clean and renewable source of energy. Their research involved the use of cobalt oxide nanoparticles to split water into hydrogen and oxygen.

Deep-sea corals record dramatic long-term shift in Pacific Ocean ecosystem

Posted: 15 Dec 2013 01:09 PM PST

Long-lived deep-sea corals preserve evidence of a major shift in the open Pacific Ocean ecosystem since around 1850, according to a new study. The findings indicate that changes at the base of the marine food web observed in recent decades in the North Pacific Subtropical Gyre may have begun more than 150 years ago at the end of the Little Ice Age.

Nanoscale friction: High energy losses in the vicinity of charge density waves
