    New approach to modeling power system aims for better monitoring and control of blackouts Нанотехнологии
    Major power outages are fairly infrequent, but when they happen they can result in billions of dollars in costs – and even contribute to fatalities. Now research from North Carolina State University has led to the development of an approach by which high-resolution power-system measurements, also referred to as Synchrophasors, can be efficiently used to develop reliable models of large power systems, which would help us keep an eye on their health.
    Fastest movie in the world recorded: Scientists develop a method to film nanostructures Нанотехнологии
    When we catch a cold, the immune system steps in to defend us. This is a well-known biological fact, but is difficult to observe directly. Processes at a molecular level are not only miniscule, they are often extremely fast, and therefore difficult to capture in action.
    Preoperative breast MRI suggests high cancer yield Нанотехнологии
    The use of preoperative Breast MRI detects otherwise occult cancer with a relatively high degree of accuracy when applied to a diverse population of patients newly diagnosed with breast cancer, according to a study in the January issue of the American Journal of Roentgenology.
    Elastography helps identify patients who need biopsy Нанотехнологии
    A new ultrasound technique is proving valuable in distinguishing malignant from benign breast lesions in some patients – results that could mean fewer unnecessary breast biopsies, a new study shows.
    Research shows emotional stress can change brain function Нанотехнологии
    Research conducted by Iaroslav Savtchouk, a graduate student, and S. June Liu, PhD, Associate Professor of Cell Biology and Anatomy at LSU Health Sciences Center New Orleans, has shown that a single exposure to acute stress affected information processing in the cerebellum – the area of the brain responsible for motor control and movement coordination and also involved in learning and memory formation. The work is published in the January 12, 2011 issue of The Journal of Neuroscience.
    Rebooting the brain helps stop the ring of tinnitus in rats Нанотехнологии
    NIH-funded researchers were able to eliminate tinnitus in a group of rats by stimulating a nerve in the neck while simultaneously playing a variety of sound tones over an extended period of time, says a study published today in the advance online publication of the journal Nature. The hallmark of tinnitus is often a persistent ringing in the ears that is annoying for some, debilitating for others, and currently incurable. Similar to pressing a reset button in the brain, this new therapy was found to help retrain the part of the brain that interprets sound so that errant neurons reverted back to their original state and the ringing disappeared. The research was conducted by scientists from the University of Texas at Dallas and MicroTransponder Inc., in Dallas.
    Cracking a tooth: 3-D map of atoms sheds light on nanoscale interfaces in teeth, may aid materials design Нанотехнологии
    Teeth and bone are important and complex structures in humans and other animals, but little is actually known about their chemical structure at the atomic scale. What exactly gives them their renowned toughness, hardness and strength? How do organisms control the synthesis of these advanced functional composites?
    Astronomers discover close-knit pairs of massive black holes Нанотехнологии
    Astronomers at the California Institute of Technology (Caltech), University of Illinois at Urbana-Champaign (UIUC), and University of Hawaii (UH) have discovered 16 close-knit pairs of supermassive black holes in merging galaxies.
    Cosmic magnifying lenses distort view of distant galaxies Нанотехнологии
    Looking deep into space, and literally peering back in time, is like experiencing the universe in a house of mirrors where everything is distorted through a phenomenon called gravitational lensing. Gravitational lensing occurs when light from a distant object is distorted by a massive object that is in the foreground. Astronomers have started to apply this concept in a new way to determine the number of very distant galaxies and to measure dark matter in the universe. Though recent progress has been made in extending the use of gravitational lensing, a letter published in Nature on Jan. 13 makes the case that the tool may be even more necessary than originally thought when looking at distant galaxies.
    Quantum quirk contained: Discovery moves quantum networks closer to reality Нанотехнологии
    Researchers at the University of Calgary, in Canada, collaborating with the University of Paderborn, in Germany, are working on a way to make quantum networks a reality and have published their findings in the journal Nature. A similar finding by a group at the University of Geneva, in Switzerland is reported in the same issue.
