 Breaking News
  • New discovery may lead to the development of super premium gasolineIn contradicting a theory that's been the standard for over eighty years, researchers have made a discovery holding major promise for the petroleum industry. The research has revealed that in the foreseeable future products such as crude oil and gasoline could be transported across country 30 times faster, and the several minutes it takes to fill a tank of gas could be reduced to mere seconds.
  • Why We Need a Distributed Computing System And Hadoop EcosystemIn this article, you will learn why we need a distributed computing system and Hadoop ecosystem.
  • Uncovering the secrets of water and ice as materialsWater is vital to life on Earth and its importance simply can't be overstated -- it's also deeply rooted within our conscience that there's something extremely special about it. Yet, from a scientific point of view, much remains unknown about water and its many solid phases, which display a plethora of unusual properties and so-called anomalies that, while central to water's chemical and biological importance, are often viewed as controversial.
  • Amber specimen offers rare glimpse of feathered dinosaur tailResearchers have discovered a dinosaur tail complete with its feathers trapped in a piece of amber. The finding helps fill in details of the dinosaurs' feather structure and evolution.
  • Researchers able to study individual defects in transistorsScientists have developed a method for studying individual defects in transistors. All computer chips, which are each made up of huge numbers of transistors, contain millions of minor ‘flaws’. Previously it was only possible to study these flaws in large numbers. However, fundamental research has now made it possible to zoom in on defects and study them individually. In due course, this knowledge will be highly relevant to the further development of the semiconductor industry.
  • Applicability of dynamic facilitation theory to binary hard disk systemsGlasses are amorphous (non-crystalline) solids that are widely used in everyday life and in technological instruments. It is important to understand the behavior of materials that form glasses; that is, to study the dynamics of their glass transition, which is the transition from the liquid state to a glass one with decreasing temperature or increasing pressure. Multiple theoretical models have been developed to explain the relaxation dynamics of materials that form glasses. One such model is the dynamic facilitation theory, which predicts that the dynamics of systems are heterogeneous and relaxation displays parabolic behavior.
  • Hidden images created with commercial inkjet printersResearchers have developed a way to use commercial inkjet printers and readily available ink to print hidden images that are only visible when illuminated with appropriately polarized waves in the terahertz region of the electromagnetic spectrum. The inexpensive method could be used as a type of invisible ink to hide information in otherwise normal-looking images.
  • Blocks of ice demonstrate levitated and directed motionResembling the Leidenfrost effect seen in rapidly boiling water droplets, a disk of ice becomes highly mobile due to a levitating layer of water between it and the smooth surface on which it rests and melts. The otherwise random rotation and translation (sliding) of the ice block can be directed by controlling the flow dynamics of the melted ice-turned-water close to the disk surface.
  • Conservation effort spreads seeds of destruction across the MidwestWeed scientists in at least two Midwestern states have been reporting for years that a conservation program meant to provide habitat for pollinating insects is sowing bad seeds -- including seeds of the potentially devastating agricultural weed Palmer amaranth -- along with the good. Now, researchers have traced the weed seeds to at least one source: pollinator habitat seed sold by a company in the Midwest.
  • Bacteria produce aphrodisiac that sets off protozoan mating swarmScientists have demonstrated that bacteria can drive mating in eukaryotes raises possibility that environmental bacteria or bacterial symbionts may influence mating in animals.
