Computer scientists develop new approach to sort cells up to 38 times faster Posted: 02 Oct 2013 11:11 AM PDT A team of engineers led by computer scientists has developed a new approach that marries computer vision and hardware optimization to sort cells up to 38 times faster than is currently possible. The approach could be used for clinical diagnostics, stem cell characterization and other applications.

Seamless photography: Using mathematical models for image stitching Posted: 02 Oct 2013 09:55 AM PDT Panoramic photographs were invented to capture large objects or scenes that could not otherwise fit within the constraints of a single photo. Panoramic photography is achieved through image stitching, a process that combines two or more photographs, seamlessly blending input images with overlapping regions into one picture.

New method allows quantitative nanoscopic imaging through silicon Posted: 02 Oct 2013 08:24 AM PDT Scientists have figured out how to quantitatively observe cellular processes taking place on so-called "lab on a chip" devices in a silicon environment. The new technology will be useful in drug development as well as disease diagnosis, researchers say.

Discovery of charged droplets could lead to more efficient power plants Posted: 02 Oct 2013 07:33 AM PDT In a completely unexpected finding, researchers have discovered that tiny water droplets that form on a superhydrophobic surface, and then "jump" away from that surface, carry an electric charge. The finding could lead to more efficient power plants and a new way of drawing power from the atmosphere, they say.

Measuring height by connecting clocks Posted: 02 Oct 2013 07:30 AM PDT How far above sea level is a place located? And where exactly is "sea level"? It is one objective of the geodesists to answer these questions with 1 cm accuracy. Conventional measurement procedures or GPS technologies via satellites, however, reach their limits here. Now optical atomic clocks offer a new approach, because the tick rate of a clock is influenced by gravity.

Spinach and nanodiamonds? nanodiamond biosensor for detection of iron-level in blood Posted: 02 Oct 2013 06:22 AM PDT Popeye, the comic book hero, swears by it as do generations of parents who delight their children with spinach. Of course, today it is known that the vegetable is not quite as rich in iron as originally thought, but that iron is nevertheless essential for our physical well-being is undisputed. Lack of iron -- caused by malnutrition -- can lead to anemia while an increased level of iron may signal the presence of an acute inflammatory response. Therefore, the blood iron level is an important medical diagnostic agent. Researchers have now developed a novel biosensor for determination of iron content that is based on nanodiamonds.

Graphene with aroma: New production method broadens prospects for 'magic' material Posted: 01 Oct 2013 06:13 AM PDT New production method broadens the prospects for an improved use of the "magic material" -- many different forms are possible.
