World fuel consumption is shifting more and more to diesel at the expense of gasoline. A recently published article in Nature Chemistry by a research team at Stockholm University and the Polytechnic University of Valencia in Spain presents a new porous material that evinces unique properties for converting gasoline directly into diesel. The material has a tremendously complex atomic structu

New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published today (1 February 2012) in Nature Geoscience.

Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases.

For decades, chemists considered a chemical pathway known as the formose reaction the only route for producing sugars essential for life to begin, but more recent research has called into question the plausibility of such thinking. Now a group from The Scripps Research Institute has proven an alternative pathway to those sugars called the glyoxylate scenario, whic

Graphene leaves a rather modest impression at a first sight. The material comprises nothing but carbon atoms ordered in a mono-layered "carpet". Yet, what makes graphene so fascinating for scientists is its extremely high conductivity. This property is particularly useful in the development of photodetectors. These are electronic components that can detect radiation and transform it into electrica

Atomic-level defects in graphene could be a path forward to smaller and faster electronic devices, according to a study led by researchers at the Department of Energy's Oak Ridge National Laboratory.

Hydrogen molecules may act as a kind of energy sink that strengthens the magnetic grip that causes sunspots, according to scientists from Hawaii and New Mexico using a new infrared instrument on an old telescope.

Researchers at Rice University are using carbon nanotubes as the critical component of a robust terahertz polarizer that could accelerate the development of new security and communication devices, sensors and non-invasive medical imaging systems as well as fundamental studies of low-dimensional condensed matter systems.

To the lengthy list of serendipitous discoveries – gravity, penicillin, the New World – add this: Scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered why a promising technique for making quantum dots and nanorods has so far been a disappointment. Better still, they've also discovered how to correct the problem.

Using computer simulations, a RUB researcher has shown that the oxygen molecule (O2) is stable up to pressures of 1.9 terapascal, which is about nineteen million times higher than atmosphere pressure. Above that, it polymerizes, i.e. builds larger molecules or structures. "This is very surprising" says Dr. Jian Sun from the Department of Theoretical Chemistry. "Other simple molecules like nitrogen
