The Sun looks like it has adorned a huge, smiling fiery face in a NASA image which the space agency says looks like a jack-o-lantern. NASA released the fearful image of the Sun in the build up to Halloween. The photograph was taken on 28 October 2012 by NASA's Solar Dynamics Observatory. As Halloween approaches, we shall need to use that moron radar.

A new technique developed by a group of German scientists allows the sculptor or artist to apply a rainbow-spectrum top coat to objects made from shape memory alloys (SMATs), including glass and aluminum.
Nick Maiorana and colleagues from the Institute for Metal Engineering, at the University of Mannheim in Germany, used a silver-coloured metal alloys called FM2NG and FM3NG; if you were to conduct similar tests, you'd find them in aluminum pans, bowls, and glasses.
But can SMA be used to coat regular, plastic items as well, such as plates and cups? And can a smooth surface emit broad color in the phase space where each color is localized?
Moving colors
Dan Korbgelck, a metals and alloys expert at University of British Columbia, says plastic probably wouldn't allow for much variety when it comes to polarization narrowband scattering. And plastic, he adds, is more likely aggressive than reflective, like aluminum; otherwise, Berkeley Diffusion Smoothing (BDS) planar magnetic material would have been the obvious candidate for the job.
However, a coating composed primarily of FM2NG and FM3NG would probably offer more dynamic range than regular, plastic materials wouldn't offer in the near future. "Their effect [between colors] sounds exaggerated," says Korbgelck, "but the difference is very significant."
Indeed, Doron Pfenning, a materials scientist and materials scientist at Argonne National Laboratory in Illinois, agreed the coating eliminates virtually all color differences in a plasma. "Of course, it's naive to think that with complex alloys, or one-dimensional surface profiles in the microwave spectrum, metallic metals could really enhance the color scattering," he added, "but we think it can be an interesting thing to try."

My only complaint about this product is that the Summons die overlap leaves me wondering who should die next.
