Predicting key property in Andromeda's satellites

Posted: 14 Feb 2013 09:06 AM PST

Using modified laws of gravity, researchers have closely predicted a key property - velocity dispersion - measured in faint dwarf galaxies that are satellites of the nearby giant spiral galaxy Andromeda.

World's most sensitive plasmon resonance sensor inspired by ancient Roman cup

Posted: 14 Feb 2013 08:16 AM PST

Utilizing optical characteristics first demonstrated by the ancient Romans, researchers have created a novel, ultra-sensitive tool for chemical, DNA, and protein analysis.

What green algae are up to in the dark

Posted: 14 Feb 2013 07:38 AM PST

How do green algae produce hydrogen in the dark? Biologists have now uncovered a mechanism for the production of the gas which has hardly been examined before; usually, researchers are interested in light-driven hydrogen synthesis.

Unlocking the mystery behind Saturn's moonlets

Posted: 14 Feb 2013 07:37 AM PST

New research by physicists casts new light on Saturn's moonlets -- and could help solve some of the mysteries surrounding planet formation. Saturn's F ring has long been of interest to scientists as its features rapid change on timescales from hours to years, and it is probably the only location in the solar system where large scale collisions happen on a daily basis.

A quantum dot energy harvester

Posted: 14 Feb 2013 04:56 AM PST

A new type of nanoscale engine has been proposed that would use quantum dots to generate electricity from waste heat, potentially making microcircuits more efficient. The engines would be microscopic in size, and have no moving parts. Each would only produce a tiny amount of power but by combining millions of the engines in a layered structure, enough of them could make a notable difference in the energy consumption of a computer.
