Stepping Back To The Moon - Space.com   "While obviously updated with new composite materials and vastly improved computing power, the new moonships specified by the likely contractors are, as new NASA chief Mike Griffin recently stated: like ‘Apollo on steroids’. As we approach this still highly risky endeavor, we should resort to established and proven technology to get there… as well we might have used had we chosen to continue our brilliant course moonward and beyond in the 1970’s," Pyle stated.     
Past gives clue to climate impact  - BBC  The reason why temperatures shot up during the Permian-Eocene Thermal Maximum are unclear; but carbon dioxide concentrations in the atmosphere appear to have been extremely high, about a thousand times higher than currently. The suspicion is that some kind of feedback mechanism may have been involved. One theory is that an initial warming changed the distribution of heat in the oceans so that deposits of gas hydrates on the sea floor were released, with carbon dioxide and methane rising to the surface and entering the atmosphere, causing further greenhouse warming.    

Getting A Handle On Minimal Surfaces - Science Daily  Left:  The top image is a traditional helicoid. The bottom one has a hole in it that would become a handle if the shape were completely untwisted into a flat surface. (Image courtesy of Indiana University)  A twisted soap bubble with a handle? If you find that hard to visualize, it's understandable. Experts had thought for more than 200 years that such a structure was not even mathematically possible. But no longer. In a paper published in the Nov. 15 issue of Proceedings of the National Academy of Sciences, mathematicians Matthias Weber of Indiana University, David Hoffman of Stanford University, and Michael Wolf of Rice University presented a proof of the existence of a new minimal surface they call a genus one helicoid. "This proof tells us that our intuition was not quite right about what is possible and what is not possible," Weber said. "Probably one reason it was not discovered sooner is that no one imagined that something like this could exist."
