Hitting Europa Hard Could Have A Real Impact - SpaceDaily  Jupiter's moon Europa is one of the most intriguing places in the solar system to Astrobiologists. An icy shell overlies a deep water ocean, and tidal flexing from Jupiter's gravity may provide energy for life. Karl Hibbetts (KH):  It's a projectile that would go really fast into the surface of Europa, creating a curtain of ejecta. So we could make measurements that reach beneath the solid surface of the moon, measurements that are not possible to make from orbit.? Astrobiology Magazine (AM): How fast could you get it to fall to the surface of Europa? KH: 13 kilometers per second. That's how fast Europa is going around Jupiter. You can come in faster than that if you want, but around 10 kilometers per second is reasonable, and that is actually how fast the Deep Impact mission went into comet Tempel 1.    
BabyBot -- Robot Modelled On Two Year-old Child -- Takes First Steps - Science Daily  BabyBot, a robot modelled on the torso of a two year-old child, is helping researchers take the first, tottering steps towards understanding human perception, and could lead to the development of machines that can perceive and interact with their environment. Called the synthetic methodology, it is essentially a method of understanding by building. There are three steps: model aspects of a biological system; abstract general principles of intelligent behaviour from the model; apply these principles to the design of intelligent robots. Model, test, refine. And then repeat.     

World-leading Microscope Shows More Detail Than Ever - Science Daily  Left:  Computer-enhanced image of viverravus acutus jaw constructed from data produced by the new microscope. (Image courtesy of Engineering and Physical Sciences Research Council.  The device could lead to advances in a range of areas, such as healthcare (in furthering, for instance, the understanding of conditions such as osteoporosis), the development of better construction materials, improved oil extraction methods and even the study of fossils. A unique 3-dimensional microscope that works in a new way is giving unprecedented insight into microscopic internal structure and chemical composition. It is revealing how materials are affected, over time, by changes in temperature, humidity, weight load and other conditions.  Like a number of other microscopes, the new microscope harnesses X-rays to provide information about an object's internal structure down to micron scale. X-ray microscopes can produce 3-d internal pictures of an object by taking a large number of 2-d images from different angles. However, the new microscope's combining of this technique with time delay integration is completely unique. Through averaging out imperfections in the image across all pixels, this approach enables the microscope to produce clearer and bigger pictures than previously possible
