What Does Water Looks Like To DNA?
2013-11-20 09:41:53

American Institute of Physics New computational method described in the Journal of Chemical Physics allows researchers to predict how biological molecules interact with water A team of biochemists and mathematicians have developed a sophisticated geometric model to predict how a biological molecule will interact with water molecules, computing the results up to 20 times faster than other existing approaches. This new approach may help researchers find new drugs to treat human...

Physicists Discover New Kind Of Friction
2013-05-15 14:09:56

Technische Universitaet Muenchen Whether in vehicle transmissions, hip replacements, or tiny sensors for triggering airbags: The respective components must slide against each other with minimum friction to prevent loss of energy and material wear. Investigating the friction behavior of nanosystems, scientists from the Technische Universitaet Muenchen (TUM) have discovered a previously unknown type of friction that sheds new light on some previously unexplainable phenomena. Friction is...

Cloud Computing Code Speeds Processing Of Data-intensive Microscopy Data
2013-02-01 10:33:43

Salk Institute In this week's Nature Methods, Salk researchers share a how-to secret for biologists: code for Amazon Cloud that significantly reduces the time necessary to process data-intensive microscopic images. The method promises to speed research into the underlying causes of disease by making single-molecule microscopy of practical use for more laboratories. "This is an extremely cost-effective way for labs to process super-resolution images," says Hu Cang, Salk assistant...

Researchers Create And Image Smallest 5-Ring Molecule
2012-05-28 07:21:59

[ Watch the Video ] A collaboration of three groups is responsible for creating and imaging the smallest structure ever -- a billionth of a meter across and nearly 100,000 times thinner than a human hair. The structure, called olympicene, because of its five-ringed shape being similar to that of the Olympic symbol, was first synthesized by University of Warwick, UK researchers, who worked closely with IBM Research - Zurich to bring the molecule to life, employing a combination of...

Researchers from the Georgia Institute of Technology and University of California San Francisco have advanced scientists' ability to view a clear picture of a single cellular structure in motion. By identifying molecules using compressed sensing, this new method provides needed spatial resolution plus a faster temporal resolution than previously possible. Despite many achievements in the field of super-resolution microscopy in the past few years with spatial resolution advances, live-cell...

Researchers Increase Speed Of Single-molecule Measurements
2012-03-19 04:22:15

New integrated circuit design could lead to cheaper, faster DNA sequencing As nanotechnology becomes ever more ubiquitous, researchers are using it to make medical diagnostics smaller, faster, and cheaper, in order to better diagnose diseases, learn more about inherited traits, and more. But as sensors get smaller, measuring them becomes more difficult–there is always a tradeoff between how long any measurement takes to make and how precise it is. And when a signal is very weak, the...

'Identity check' selectively screens single molecules passing through nanopores A novel type of sensor, based on nanometer-scale pores in a semiconductor membrane, is a step closer to practical use in applications such as analyzing the protein contents of a single cell. Researchers pioneering single-molecule nanopore sensor technology at the Technische Universität München (TUM) have shown its potential through a succession of experiments over the past few...

A new study in the Journal of General Physiology (www.jgp.org) uses state-of-the-art fluorescence microscopy to provide a striking 3-D picture of how class V myosins (myoV) "walk" along their actin track. The myosin superfamily of mechanoenzymes, more commonly referred to as molecular motors, play an important role in muscle contraction and other basic cellular processes. MyoV, one of the most highly studied molecular motors, has the ability to travel long distances by taking multiple...

Experimental confirmation of a fundamental physical theorem The so-called ergodic theorem formulates a fundamental physical principle relating to the behavior of dynamical systems. Essentially the theorem states that in a multiparticle system each individual particle behaves just as “chaotically” as does the system as a whole. In other words, one can extrapolate from the behavior of a single element to that of the whole system. Strangely enough, in spite of its wide-ranging...


Word of the Day
glogg
  • Scandinavian punch made of claret and aquavit with spices and raisins and orange peel and sugar.
This word comes from the Swedish 'glogg,' which is an alteration of 'glodgat,' mulled (wine).
