Wed, 02 Jul 2008 Super Atoms Turn Periodic Table Upside Down. Researchers have developed a technique for generating atom clusters made from silver and other metals. Surprisingly enough, these so-called super atoms (clusters of 13 silver atoms, for example) behave in the same way as individual atoms and have opened up a whole new branch of chemistry.more

Tue, 01 Jul 2008 New Electrostatic-based DNA Microarray Technique Could Revolutionize Medical Diagnostics. Researchers have invented a technique in which DNA assays -- the key to personalized medicine -- can be read and evaluated with no need of elaborate chemical labeling or sophisticated instrumentation. Based on electrostatic repulsion that yields images visible to the naked eye, the technique could revolutionize the use of DNA microarrays for both research and diagnostics. more

Tue, 01 Jul 2008 Physicists Create Millimeter-sized "Bohr Atom". Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, physicists have created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved. The scientists used lasers and electric fields to coax potassium atoms into a precise configuration with one point-like, "localized" electron orbiting far from the nucleus.more

Mon, 09 Jun 2008 Magnet-controlled Camera In The Body. Images from inside the body? It can be done with tiny cameras which the patient has to swallow. In the past there was no way of controlling the device as it passed through the body. Now it can be steered and stopped where desired, and even deliver images of the esophagus.more
