New method of monitoring protein molecules using gold nanoparticles Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have developed a new method of observing individual proteins. Detailed knowledge of the dynamics of proteins is necessary in order to understand the related biological processes that occur on the molecular level. To date, this information has been obtained by means of labeling proteins with fluorescent substances, but unfortunately this changes the proteins...

Individual cells modified to act as sensors using fluorescence are already useful tools in biochemistry, but now they can add good timing to their resumé, thanks in part to expertise from the National Institute of Standards and Technology (NIST). With the added capability to track the timing of dynamic biochemical reactions, cell sensors become more useful for many studies, such as measurements of protein folding or neural activity. As described in the Journal of the...

Max Planck scientists in Göttingen have for the first time made finest details of nerve cells in the brain of a living mouse visible. To explore the most intricate structures of the brain in order to decipher how it functions — Stefan Hell´s team of researchers at the Max Planck Institute for Biophysical Chemistry in Göttingen has made a significant step closer to this goal. Using the STED microscopy developed by Hell, the scientists have, for the first...

Study finds protein's entwined arm movements may control fate of potentially toxic payload Like a magician employing sleight of hand, the protein mitoNEET -- a mysterious but important player in diabetes, cancer and aging -- draws the eye with a flurry of movement in one location while the subtle, more crucial action takes place somewhere else. Using a combination of laboratory experiments and computer modeling, scientists from Rice University and the University of California, San Diego...

University of Illinois researchers have shown that by tuning the properties of laser light illuminating arrays of metal nanoantennas, these nano-scale structures allow for dexterous optical tweezing as well as size-sorting of particles. "Nanoantennas are extremely popular right now because they are really good at concentrating optical fields in small areas,” explained Kimani Toussaint, Jr., an assistant professor of mechanical science and engineering at the University of Illinois at...

SINGAPORE, Dec. 27, 2011 /PRNewswire/ -- The Intellectual Property portfolio of TIGR® Matrix Surgical Mesh has been further complimented with the granting of a second U.S. patent related to material degradation and mechanical behaviour. TIGR® Matrix was developed based on the hypothesis that soft tissue positively remodels in response to the stimulus of increased mechanical load - a process known as 'mechanotransduction', which is the physiological process by which cells...

Supercomputer simulations at the Department of Energy's Oak Ridge National Laboratory are giving scientists unprecedented access to a key class of proteins involved in drug detoxification. Jerome Baudry and Yinglong Miao, who are jointly affiliated with ORNL and the University of Tennessee, have performed simulations to observe the motions of water molecules in a class of enzymes called P450s. Certain types of P450 are responsible for processing a large fraction of drugs taken by humans....

Model shows that signal clarity only improves if specific energy conditions are met Scientists have shown the energy conditions, under which a weak signal supplied to a physical system emerges as a stronger signal at the output thanks to the presence of random noise (a process known as stochastic resonance), in a paper that has just been published in EPJ B´. Stochastic resonance goes against the intuitive idea that where noise is present, the signal tends to fade. It occurs in...

[ Watch the Video ] A biological model system that dead-ends in an 'absorbing state' Supplied with sufficient energy, a freight train would ride the rails as far as they go. But nature also knows systems whose dynamics suddenly turn into a kind of endless loop. Like in a hamster wheel, a train caught up in such a system would continue running, but without moving forward. Scientists from the Cluster of Excellence Nanosystems Initiative Munich have now succeeded in building a simple model...
