Physicists tweak quantum force
Cymbals don’t clash of their own accord – in our world, anyway. But the quantum world is bizarrely different. Two metal plates, placed almost infinitesimally close together, spontaneously attract each other.

Room temperature superconductivity
Scientists at the University of Cambridge have for the first time identified a key component to unravelling the mystery of room temperature superconductivity, according to a paper published in today's edition of the scientific journal Nature.

Fascinating analysis of pioneer anomaly
Another blogger here, who is generally so far off the mark that I don't want to point to his earlier discussion, had some odd things to say about the "Pioneer anomaly," the unexplained deviation of the two Pioneer spacecraft from their predicted trajectory as they pass through the outer reaches of the solar system.
A much more cogent discussion has just appeared.
