Oldest Bird Was Actually a Dinosaur - For 150 years, Archaeopteryx held the "world's oldest known bird" record, but scientists now believe this animal was a dinosaur. - A new, small dinosaur from China shares traits with Archaeopteryxand likely evolved from it. - Many dinosaurs experimented with flight and feathers, but only some evolved into birds and survived extinction. Archaeopteryx, widely regarded as being the world's oldest known bird, has just been knocked off its scientific perch, since new research concludes this feathered animal was, in fact, a dinosaur. The study, published in the latest issue of the journal Nature, falls on the 150th anniversary of Archaeopteryx's discovery. With Archaeopteryx likely removed from the bird family tree, a few other prehistoric species now become the world's oldest known birds.

Technology The same image data drives both RGB stripe and PenTile RGBW™ displays. However, conventional RGB stripe displays render (draw) images by assigning a color and luminance (brightness) to an entire RGB-triplet as a whole pixel, adjusting its three RGB subpixels to set a single addressable point. Images on a PenTile RGBW™ panel are subpixel rendered, meaning they are drawn at the subpixel level (the individual points of light), rather than to the whole pixels of an RGB stripe display. Subpixel rendering dramatically increases addressability and enables the sophisticated image processing used in PenTile RGBW™ displays.
FRIDA Robot will Make your Gadget Meet FRIDA – a two handed concept robot for industrial assembly applications. This striking creation might be able to bridge the gap between fully manual assembly and fully automated manufacturing lines. The Frida project was started back in 2007 with a core team of Swiss researchers from ABB team that was then complemented by other teams from Sweden, Norway, Germany, the United States and China. The prototypes were manufactured and assembled in Sweden but many students from different universities around the world were also involved in different stages of the development. FRIDA was created in order to meet changing scenarios frequently encountered in the consumer electronics industry and other sectors. FRIDA come as dual-arms which are integrated into the torso of the unit. Key technology features: Currently several prototypes have left the lab and are being tested in pilot applications, with more work required to reach a fully agile assembly scenario.
Justin - Humanoid Robot Catches with Two Hands German researchers developed a robot that can perform complex tasks such as catching a ball in mid flight. The new robot called “Justin” is described as a two-arm-system for investigation of two handed manipulation. The development of humanoid robots has made significant progress in recent years. Although several systems have impressive walking abilities, when it comes to their abilities to manipulate objects or interact with their surrounding they are quite limited. To overcome this limitation, researchers from the German Aerospace Center (DLR) Institute of Robotics and Mathematics developed a human-like torso with two arms and two hands. The researchers see the future of humanoid robots in household assistance as well as in space environments. Justin does not have human-like legs; instead it uses wheels to move from one place to another. More information on the project can be found on the DLR website.
Martian Rivers and Lakes Giant cracks that crisscross to form polygons have been imaged on the floors of hundreds of Martian impact craters by NASA’s Mars Reconnaissance Orbiter. Scientists have been aware of them for years, but assumed they resulted from the expansion and contraction of the craters’ floors due to temperature fluctuations. A closer look at the Martian crater polygons shows cracks on both large and small size scales. unification, spacetime foam, quantum vacuum, quantum fluctuations Physics of the early Universe is at the boundary of astronomy and philosophy since we do not currently have a complete theory that unifies all the fundamental forces of Nature at the moment of Creation. In addition, there is no possibility of linking observation or experimentation of early Universe physics to our theories (i.e. it's not possible to `build' another Universe). Our theories are rejected or accepted based on simplicity and aesthetic grounds, plus their power of prediction to later times, rather than an appeal to empirical results. This is a very difference way of doing science from previous centuries of research. Our physics can explain most of the evolution of the Universe after the Planck time (approximately 10-43 seconds after the Big Bang). Another way of seeing this problem is trying to reproduce the Greek philosophers thinking about matter, as applied to spacetime.
