Oceanic Volcanoes Reveal Signs Of Ancient Earthen Crust
2013-04-25 07:27:13

For a long time now, scientists have been convinced that lava that has erupted from certain oceanic volcanoes contains material from the crust of early Earth, but decisive evidence has been elusive.

Waste Sulfur Transformed To Improve Batteries
2013-04-15 11:06:40

A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for electric cars, reports a University of Arizona-led team. The new plastic has other potential uses, including optical uses.

Fluffy Antarctic Snow Provides New Insights On Climate Cycles
2013-02-26 10:35:56

A team of scientists has found particles from the upper atmosphere trapped in a deep pile of fluffy Antarctic snow that hold clear chemical traces of global meteorological events.

Cooking Up Our Solar System, What's The Recipe?
2013-02-21 05:05:42

A research team from the University of California, San Diego is hoping to learn how our solar system evolved by studying the origins of different isotope ratios among the elements that make up today’s smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust.

The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's.

New Study May Hold Clue To Proving the Gaia Theory
2012-05-18 04:30:16

The Gaia Hypothesis proposes that the Earth is actually a giant living organism, and a University of Maryland (UMD) study might have found the key to unlocking this mystery.
