| Bright nearby double star Fomalhaut is actually a triple Posted: 03 Oct 2013 05:50 PM PDT The nearby star system Fomalhaut -- of special interest for its unusual exoplanet and dusty debris disk -- has been discovered to be not just a double star, as astronomers had thought, but one of the widest triple stars known.  |
| Physicists 'entangle' microscopic drum's beat with electrical signals Posted: 03 Oct 2013 11:26 AM PDT Extending evidence of quantum behavior farther into the large-scale world of everyday life, physicists have "entangled" -- linked the properties of -- a microscopic mechanical drum with electrical signals.  |
| Chemistry with sorted molecules: Reaction rate of many molecules depends on their shape Posted: 03 Oct 2013 11:26 AM PDT Most molecules occur in several shapes, which may behave very differently. Using a sorting machine for molecules, chemists can now for the first time directly measure the various reaction rates of different forms of the same compound.  |
| 3-D printing: The greener choice Posted: 03 Oct 2013 10:23 AM PDT A life cycle impact analyses on three products, an orange juicer, a children's building block and a water spout, showed that making the items on a basic 3-D printer took from 41 percent to 64 percent less energy than making them in an overseas factory and shipping them to the US.  |
| 3-D dynamic imaging of soft materials Posted: 03 Oct 2013 10:22 AM PDT Through a combination of transmission electron microscopy and ta unique graphene liquid cell, researchers have recorded the three-dimensional motion of DNA connected to gold nanocrystals, the first reported use of TEM for 3D dynamic imaging of soft materials.  |
| New small-molecule catalyst does the work of many enzymes Posted: 03 Oct 2013 10:22 AM PDT Researchers report that they have created a human-made catalyst that is an "enzyme mimic." Unlike most enzymes, which act on a single target, the new catalyst can alter the chemical profiles of numerous types of small molecules. The catalyst -- and others like it -- will greatly speed the process of drug discovery, the researchers say. Their findings appear in the Journal of the American Chemistry Society.  |
| Great potential for faster diagnoses with new method Posted: 03 Oct 2013 08:02 AM PDT The more accurately we can diagnose a disease, the greater the chance that the patient will survive. That is why many researchers are working to improve the quality of the diagnostic process. Researchers have discovered a method that will make the process faster, cheaper and more accurate. This is possible, because they are combining advanced tools used in physics for research in biology at nanoscale, two scientific disciplines usually very distant from each other.  |
| The art of amplification: A desktop-size 10 terawatt laser Posted: 03 Oct 2013 06:30 AM PDT A compact new generation optical amplifier has been constructed. The apparatus is extremely efficient and small enough to fit on a desktop and is able to generate over 10 terawatt light pulses.  |
| New MRI technique detects genetic condition that attacks the heart, brain, nerves Posted: 02 Oct 2013 03:56 PM PDT A genetic condition that attacks multiple organs and usually results in fatal heart problems can be detected using a new MRI technique. The discovery of this new diagnostic tool has resulted in updated clinical guidelines for the diagnosis and treatment of Fabry disease in Canada.  |
| Imaging system can help diagnose disease, monitor hazardous substances Posted: 02 Oct 2013 08:24 AM PDT To meet demands for ever smaller imaging systems, researchers are working to create entirely unconventional ways of focusing light. In pursuit of this vision, engineers have built a novel type of imaging system inspired by the elegance and relative mechanical simplicity of the human eye.  |
