Sophisticated electron-imaging technique reveals widespread "destruction," offering clues to how material works as a superconductor
It's a basic technique learned early, maybe even before kindergarten: Pulling things apart - from toy cars to complicated electronic materials - can reveal a lot about how they work. "That's one way physicists study the things that they love; they do it by destroying them," said Séamus Davis, a physicist at the U.S. Department of Energy's (DOE) Brookhaven...Read Full Story

A research group led by ETH Zurich has now, for the first time, visualized the motion of electrons during a chemical reaction. The new findings in the experiment are of fundamental importance for photochemistry and could also assist the design of more efficient solar cells. In 1999, Ahmed Zewail was awarded the nobel prize in chemistry for his studies of chemical reactions using ultrashort laser pulses. Zewail was able to watch the motion of atoms and thus visualize transition states on the...Read Full Story

A gene is a segment of DNA containing the code used to synthesize a protein. A chromosome contains hundreds to thousands of genes. Every human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is usually determined by more than one gene. Some traits are caused by abnormal genes that are inherited or that are the result of a mutation. Proteins are probably the most important class of material in the body. Proteins are not...Read Full Story
Our cells are filled with complexes that can contain dozens of proteins, all with precise interactions that ensure the complex comes together and functions in a consistent manner. These complexes, which can contain dozens of individual proteins, often have activities that mimic those of human-produced equipment, and have earned the nickname "molecular machines" accordingly.
If a molecular machine requires so...
An inflammation-promoting protein triggers deactivation of a tumor-suppressor that usually blocks cancer formation via the NOTCH signaling pathway, a team of researchers led by scientists at The University of Texas MD Anderson Cancer Center reports today in Molecular Cell.
Optical techniques enable us to examine single molecules, but do we really understand what we are seeing? After all, the fuzziness caused by effects such as light interference makes these images very difficult to interpret. Researchers have now adopted a "reverse" approach to spectroscopy which cleaned up images by eliminating background noise.
Among them are the German Heart Center, one of the most renowned transplantation centers, the Max-Delbrück-Center for Molecular Medicine and the Max-Planck-Institute for Molecular Genetics. The scientific research at these institutions is complemented by ...
