Thu, 10 Jul 2008 Early Warning System For Earthquakes: Seismic "Stress Meter" Warned Of Earthquake 10 Hours In Advance. Although measurement techniques surrounding earthquakes have improved enormously over the last few decades, it has remained very difficult to measure changes in the crust that could enable earthquake prediction. Now, scientists have measured interesting changes in the speed of seismic waves that preceded two small earthquakes by 10 and 2 hours. These measurements are an encouraging sign that hold promise for the field of earthquake prediction. more

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 Lower Crop Yields Due To Ozone A Factor In World Food Crisis. Heat waves, droughts and fuel prices are just a few reasons for the current global food crisis that is making headlines around the world. New research indicates that rising background levels of ozone in the atmosphere are a likely contributor to the problem, lowering the yield of important food crops, such as wheat and soybeans.more
