What has Curiosity found on Mars?

 Popular Science says to expect some earth shattering news from Mars in the next few weeks:

"Curiosity’s principal investigator, John Grotzinger, was quoted on NPR Tuesday morning saying the team might have some very big news soon. “Earthshaking” was the word of choice from NPR’s science correspondent, Joe Palca. Palca was apparently in Grotzinger’s office when some of the data from SAM started streaming in through the Deep Space Network last week."

Simple Math Could Bridge Quantum Mechanics and General Relativity

One of the great problems of modern physics has been the failure to reconcile the theory of quantum mechanics, which deals with the behavior of fundamental particles, with Einstein’s general theory of relativity, which describes gravity and therefore the behavior of things on a larger scale.  There are some inherent contradictions in the two theories that suggest areas where our understanding is incomplete.

This article at the Scientific American website discusses a recent paper that uses "simple math" to "present a straightforward way for quantum particles to move smoothly from one kind of ‘topological space’ to a very different one."  The article notes that while this may present progress in the reconciliation of the two theories, there is no claim the the theories have been brought together in unifying a theory of quantum gravity:

The analysis does not model gravity explicitly, and so is not an attempt to formulate a theory of ‘quantum gravity’ that brings general relativity and quantum mechanics under one umbrella. Instead, the authors, including Nobel laureate Frank Wilczek of the Massachusetts Institute of Technology (MIT) in Cambridge, suggest that their work might provide a simplified framework for understanding the effects of gravity on quantum particles, as well as describing other situations in which the spaces that quantum particles move in can radically alter, such as in condensed-matter-physics experiments.
