| At small scales, tug-of-war between electrons can lead to magnetism Posted: 29 Jun 2011 02:12 PM PDT At the smallest scales, magnetism may not work quite the way scientists expected, according to a recent article.  |
| 'Odd couple' binary makes dual gamma-ray flares Posted: 29 Jun 2011 02:12 PM PDT In December 2010, a pair of mismatched stars in the southern constellation Crux whisked past each other at a distance closer than Venus orbits the sun. The system possesses a so-far unique blend of a hot and massive star with a compact fast-spinning pulsar. The pair's closest encounters occur every 3.4 years and each is marked by a sharp increase in gamma rays, the most extreme form of light.  |
| Posted: 29 Jun 2011 10:25 AM PDT Scientists have used lasers to peek into the complex relationship between a single electron and its environment, a breakthrough that could aid the development of quantum computers.  |
| Scientists use 'optogenetics' to control reward-seeking behavior Posted: 29 Jun 2011 10:25 AM PDT The findings suggest that therapeutics targeting the path between two critical brain regions, the amygdala and the nucleus accumbens, represent potential treatments for addiction and other neuropsychiatric diseases.  |
| Universe's most distant quasar found, powered by massive black hole Posted: 29 Jun 2011 10:25 AM PDT A team of European astronomers has used European Southern Observatory's Very Large Telescope and a host of other telescopes to discover and study the most distant quasar found to date. This brilliant beacon, powered by a black hole with a mass two billion times that of the Sun, is by far the brightest object yet discovered in the early Universe.  |
| Scientists develop sensitive skin for robots: Intelligent machines develop 'self-awareness' Posted: 29 Jun 2011 09:30 AM PDT Robots will soon be able to feel heat or gentle touching on their surfaces. Researchers in Germany are now producing small hexagonal plates which when joined together form a sensitive skin for "machines with brains." This will not only help robots to better navigate in their environments, it will also enable robot 'self-perception'. A single robotic arm has already been partially equipped with sensors and proves that the concept works.  |
| 'Sensing skin' could monitor the health of concrete infrastructure continually and inexpensively Posted: 29 Jun 2011 09:28 AM PDT Civil engineers and physicists have designed a new method for the electronic, continual monitoring of concrete infrastructure. The researchers say a flexible skin-like fabric with electrical properties could be adhered to areas of structures where cracks are likely to appear, such as the underside of a bridge, and detect cracks when they occur. Installing this "sensing skin" would be as simple as gluing it to a structure's surface.  |
| Moving microscopic vision into another new dimension Posted: 29 Jun 2011 07:21 AM PDT Scientists who pioneered a revolutionary 3-D microscope technique are now describing an extension of that technology into a new dimension that promises sweeping applications in medicine, biological research, and development of new electronic devices.  |
